How to perform regular inspection and maintenance of consumables of concrete laser leveling machine ※1. Overview of consumables Concrete laser leveling machine is an indispensable large-scale equipment in modern construction. Regular inspection and maintenance of its consumables are of great significance to ensure construction quality and efficiency. Consumables mainly include scrapers, cutting blades, crawlers, filters, hydraulic oil, etc. The condition of these components and materials is directly related to the performance and service life of the leveler. ※2.Inspection cycle setting In order to ensure the stable operation of the leveling machine, a reasonable inspection cycle must be set. It is generally recommended that new machines be inspected every half month in the first three months, and then checked once a month. After one year of operation, it is recommended to be inspected every three months. For equipment with harsh working environment or high frequency of use, the inspection cycle should be shortened appropriately. ※3.Inspection of worn parts Check the wear of scrapers, cutting blades and other easily worn parts, especially those in direct contact with concrete. During inspection, attention should be paid to whether there are cracks, breaks, excessive wear, etc. At the same time, check whether the tracks are worn, broken or loose, and whether there are foreign objects embedded in them. ※4. Consumable replacement standards Establish reasonable replacement standards based on component wear and recommendations in the instruction manual. For example, when the scraper wear thickness exceeds 5mm, replacement should be considered; when the scraper blade is severely deformed or wear exceeds 2mm, it needs to be replaced; when the track wear exceeds 1/3 of the original thickness, new parts should be replaced. Properly setting replacement standards can avoid equipment performance degradation. ※5. Detailed explanation of maintenance steps (1) Cleaning equipment: Regularly clean the dust and concrete residue on the surface of the leveler to keep the equipment clean. (2) Check the oil: Check whether the hydraulic oil, gear oil and other oils are sufficient and clean. If they are contaminated or insufficient, they should be replaced and replenished in time. (3) Tighten loose parts: Check whether all parts of the equipment are loose, and if so, tighten them in time. (4) Replacement of consumables: timely replacement of seriously worn parts and consumables in accordance with set replacement standards (5) Lubrication and maintenance: Lubricate and maintain the parts that need lubrication to ensure smooth operation of the equipment. ※6.Safety precautions (1) When performing inspection and maintenance, be sure to ensure that the equipment has completely stopped running and disconnected from the power supply to avoid accidents. (2) Use appropriate tools and equipment for maintenance to avoid equipment damage or personal injury caused by the use of inappropriate tools. (3) During the maintenance process, pay attention to safety measures such as fire prevention and electric shock prevention to avoid safety accidents. ※7.Performance optimization suggestions (1) Regularly conduct overall performance testing of the equipment, including flatness, speed, accuracy and other indicators to ensure stable equipment performance. (2) Based on the test results, adjust the parameters and settings of the equipment in a timely manner to achieve optimal performance. (3) Strengthen the training of operators to improve operation level and equipment usage efficiency, ※8. Records and reports Establish a complete inspection and maintenance record system to record in detail the time, content, problems discovered and measures taken for each inspection. Major problems and maintenance situations should be reported to superiors in a timely manner so that timely measures can be taken to solve the problems. At the same time, inspection and maintenance records are regularly analyzed and summarized to discover the rules and trends of equipment operation and provide data support for equipment preventive maintenance and fault prediction. In short, regular inspection and maintenance of the consumables of the concrete laser leveling are the key to ensuring stable operation of the equipment and extending its service life.

    There are various methods for basement floor construction. Among them, the construction of diamond sand floor and diamond sand floor with curing agent is favored by many real estate projects due to its economic, wear-resistant, pressure-resistant, anti-pollution and easy-to-clean features. However, improper manufacturing processes can also lead to quality issues and potential risks. This article will respectively introduce the diamond sand wear-resistant floor from the perspective of technology and the prevention and control of common problems. 1. Diamond sand floor Compared with ordinary concrete floors, diamond sand floors have better wear resistance, compressive strength and impact resistance, and have a longer service life. However, from the perspective of microstructure, the surface of the diamond sand floor is relatively rough, and the capillary structure of concrete has a low resistance to the penetration, pollution and corrosion of substances such as acids, alkalis and oils. 2. Corundum + cured floor The construction of adding curing agent to the diamond sand floor. When the diamond sand floor is applied with a curing agent, it better makes up for the above deficiencies. Moreover, as the curing agent penetrates and forms a film, it enhances the integrity of the original surface, significantly improving its surface strength and wear resistance. After long-term use, it is obviously superior to the ordinary diamond sand floor in terms of cracking, powdering, and dusting, and is also easier to clean. It has extremely strong wear resistance, pressure resistance and impact resistance The diamond sand floor itself has excellent wear resistance. After adding a curing agent, the strength and hardness of the floor are further enhanced, and its wear resistance, pressure resistance and impact resistance are also significantly improved, and the durability of the floor is greatly enhanced. 2) Prevent sanding and dusting The main advantage of the diamond sand reinforced floor is its ability to prevent sanding and dusting. After the application of the curing agent, the surface hardness (indicated by the diameter of the indentation) and wear resistance (indicated by the length of the grinding pit) can be effectively enhanced. The surface becomes denser and has better integrity, which can effectively prevent sanding and dusting. 3) Waterproof, oil-proof and anti-corrosion The surface of a common diamond sand floor has pores that are hard to see with the naked eye. Water, oil and other corrosive liquids can seep into the interior of the floor through these holes and gaps. The most notable feature of the curing agent is its excellent sealing property, just like coating the floor with a film to prevent erosion. 1. The surface of the floor is firmly combined with the base layer, without any hollowing or sanding phenomena. 2. Surface layer quality: Uniform color, no obvious color difference, no scratches, no slag inclusions. The surface must not have cracks and hollowing is not allowed. 3. Gloss requirements: Achieve medium to high brightness, and the lamp should have a reflective effect when illuminated. 4. Joint: Uniform width, and the inside of the joint should be thoroughly cleaned. 5. The hardness of the floor should reach above 6.5 on the Mohs scale (tested by a hardness tester). 6. The trachoma rate shall not exceed 3 per square meter. 1. The strength of the concrete shall not be lower than C25. 2. The smallest possible water-cement ratio. A water-cement ratio that is too high can cause bleeding on the concrete surface and reduce the compressive strength of the concrete surface. Therefore, the water-cement ratio should be as small as possible, generally controlled below 0.5. 3. Commercial concrete should be used as much as possible. If on-site mixed concrete is used, its slump should be controlled at 1 to 3cm. The slump of commercial concrete is between 12 and 14cm. The diameter of the larger crushed stones shall not exceed 30mm. 4. When the concrete thickness is greater than 8cm, ordinary concrete should be used for pouring; when the concrete thickness is less than 8cm, fine aggregate concrete should be used for pouring. 5. Concrete should be leveled immediately after pouring, with a flatness of no more than 2mm within a 2-meter range. 6. Before the surface layer construction, the base concrete and vibration slurry should be sufficient (not less than 5mm). 7. The mud content of sand and gravel in concrete shall not exceed 2%. 8. After vibration grouting, the bleeding of the concrete should be uniform. If there are water pits, they must be removed and the surface leveled again; otherwise, the flatness of the diamond sand floor construction cannot be guaranteed. 1. Construction of diamond sand floor 1) The ground concrete is poured in sections and leveled immediately after pouring. When multiple locations are being poured simultaneously, pay attention to the construction sequence being carried out in one direction and consider the consistency of the mating surfaces. ② Concrete should be leveled with a long roller or a long straightedge after being pushed flat. Three to five hours after the concrete is poured, it should be observed that there is no bleeding on the surface and it has reached the initial setting state. 2) Use a mechanical trowel to tap the slurry in a round motion. For fine areas, use a wooden trowel to trim the edges. The main purpose is to smooth the concrete surface and reduce the floating slurry. Pay attention to troweling in the same direction as pouring. 3) Sprinkle the wear-resistant aggregate in two batches. In the first batch, evenly spread two-thirds of the wear-resistant material on the already troweled cement floor. 4) For the second time, evenly spread the remaining 1/3 of the wear-resistant material on the surface of the concrete, and use a mechanical trowel with a disc installed to work crisscross and cross at least twice. 5) Use a mechanical trowel (metal disc) to smooth it out multiple times back and forth. For the fine corners and edges, use a manual trowel in coordination with the construction. The time for the next process should be determined based on the temperature and humidity. 6) When the surface of the floor begins to harden, use a mechanical trowel with a metal blade to grind and smooth it, and repeat this operation 3 to 4 times. (Construction workers must wear soft flat shoes to avoid damaging the surface. The fine corners and edges should be polished by hand.) 7) Water curing should be carried out on the polished wear-resistant floor (mainly to prevent the evaporation of surface moisture and ensure the stable growth of the wear-resistant material's strength). The curing period is 7 days. 8) After the surface has cured for a certain period of time (5 to 6 hours after the completion of the wear-resistant material floor), use a mechanical trowel equipped with a metal blade for the final polishing and leveling. 9) Mold and compartment cutting (this can be done according to the actual situation on site and the owner's needs). Mold removal can be carried out the day after the completion of the diamond sand floor. During the operation, be careful not to damage the edge of the floor. The size of the compartments shall be determined by Party A on the third day after the completion of the diamond sand floor. 2. Application of penetrating liquid hardener (commonly known as curing agent) The original color of the diamond sand floor should be cured for more than 14 days, while the colored diamond sand floor usually needs to be cured for 28 days. Only after the color has matured can the penetrating liquid hardener be applied. The specific measures are as follows: Before construction, clean and remove debris, oil stains, paints, curing agents, etc. from the ground. If there are any pits or cracks, they should be repaired in advance with cement-based jointing mortar and maintained for 3 days. If no repair is needed, proceed with the construction directly. 2) Sprinkle water on the base layer until it is fully moistened. Do not sprinkle too much. 3) Use a 50-mesh resin grinding disc to grind the base layer, removing the floating slurry and stains on the base layer to make it free of roughness and gradually smooth. 4) After the 50-mesh grinding is completed, use a 150-mesh resin grinding disc for grinding. After grinding, use a high-power vacuum cleaner to suck up the mud and sewage on the surface of the base layer. 5) Sprinkle water on the surface of the base layer and grind it with a 300-mesh resin grinding disc (the ground should be ground evenly in a grid pattern, and the machine's pushing speed should be one step per second to grind off the remaining materials and fine scratches on the ground). After grinding, grind it with a 500-mesh grinding disc. Then, use a vacuum cleaner to suck up the wastewater and ventilate to dry the base layer. 6) After the base layer is dry, if the surface turns slightly white, apply the concrete sealant and hardener. Sprinkle the material evenly and spread it evenly with a mop. Keep the base layer surface moist for 30 minutes. If there is rapid penetration in some areas and it has dried, sprinkle the material again and use a mop to evenly moisten the base layer. 7) After 30 minutes, the surface of the concrete sealant and hardener begins to thicken. Water should be sprinkled on its surface and pushed back and forth with a long-bristled brush or floor scrubber to dilute the excess hardener and better penetrate into the base layer. After one hour, the excess material and water should be sucked dry with a vacuum cleaner to ensure that the base layer is dry for more than 12 hours. 8) After 12 hours, sprinkle water on the base surface of the completed construction material, and grind it with a 500-mesh resin grinding disc to remove the excess material. Then, grind it with a 1000-mesh grinding process. After grinding, use a vacuum cleaner to suck up the wastewater. 9) After 12 hours, the base layer has basically dried. Then, it is ground and polished with a 2000-mesh resin grinding disc to gradually give its surface a lustrous appearance. 10) For each mesh size, the grinding discs should be cross-ground 3 to 5 times in both the longitudinal and transverse directions. 11) Special treatment ① Corner and edge treatment: Large machinery can only be used for large-scale grinding. For corner and edge positions, a portable Angle grinder should be used for grinding and polishing, following the same method as for large-scale construction. When the base layer has poor strength and severe sanding, it is necessary to reinforce the base layer first, and then proceed with the normal construction process. First, use a 300-mesh resin grinding disc to remove the floating slurry on the surface of the base layer. Then, evenly sprinkle the concrete sealant and hardener to ensure it fully wets and penetrates into the base layer. After 12 hours, when the concrete sealant and hardener has cured and the strength of the base layer has improved, follow the normal process: 50-mesh grinding (water grinding) → 150-mesh grinding (water grinding) → 300-mesh grinding (water grinding) → construction materials → 12-hour drying and curing → 500-mesh grinding (water grinding) → 1000-mesh grinding (water grinding) → 2000-mesh grinding (dry grinding). The aesthetic effect of the floor cannot be achieved without meticulous control during the construction process. Besides strictly adhering to the corresponding techniques and methods, the prevention of common quality problems also requires attention. If the construction is not done properly, many problems will occur during later use. Now let's talk about the common quality problems of the diamond sand wear-resistant floor and how to prevent them. There are mainly three reasons for the color difference of corundum: 1) Material selection issues; 2) The materials were not spread in several portions, the amount of materials used was insufficient, and the thickness was uneven. 3) Maintenance issues: The use of covering with plastic film for maintenance led to uneven evaporation of ground moisture. The area where the film comes into contact with the floor is whitish, while the area where it does not touch the floor is normal in color. Preventive measures Choose a manufacturer with stable and reliable product quality and a good reputation. 2) The spreading of materials should be carried out strictly in accordance with the requirements of the briefing in several portions, with a usage of no less than 5kg/m². 3) Plastic film curing is strictly prohibited. During summer construction, water spraying curing can be adopted in several batches (with an interval of 2 to 3 hours). The allowable deviation of ground flatness is ≤2.5mm/2m in both longitudinal and transverse directions. The reasons for the deviation during construction are: 1) The template setup is out of tolerance; 2) The concrete part was not leveled in accordance with the standard. 3) The wear-resistant material is not evenly spread. Preventive measures 1) Strictly calibrate the elevation lines. Set up steel rods every 2 meters or so. The elevation of the steel rods should be the same as that on the longitudinal seam formwork. Check with a level. 2) The joints should be roughened and leveled in advance. When pouring new concrete, the levelness should be consistent with that of the already poured ground. Any low-lying areas should be replenished and filled in a timely manner. 3) Wear-resistant aggregates should be spread in two portions. The first dosage should be two-thirds of the total dosage. Ensure that the mixture falls evenly. Do not throw it forcefully to avoid the separation of aggregates and cement. After the wear-resistant material has absorbed a certain amount of moisture, it is ground and dispersed with a grinding machine and then combined with the base concrete slurry. For the second spreading, apply the remaining one-third in a direction perpendicular to that of the first spreading. When spreading, first use a straightedge or a straight scraper to measure the levelness, and adjust the uneven areas of the first spreading. After spreading, immediately smooth and polish it, and repeat the grinding machine operation at least twice. When the grinding machine is in operation, it should be carried out alternately in the longitudinal and transverse directions, evenly and orderly, to prevent material accumulation. The third time mainly involves repair treatment. For low-lying areas, materials are replenished and leveled. For corners and edges that cannot be covered by the grinding machine, manual flattening and smoothing are adopted. There are the following situations regarding ground cracks: If the initial setting time of concrete is not well controlled and the diamond sand wear-resistant aggregate is scattered when the moisture content of the concrete is relatively low, it is easy to cause cracks after the construction is completed. 2) Improper construction methods, insufficient thickness of the wear-resistant layer (corundum layer), rapid water loss (such as excessive construction environment atmosphere, etc.), resulting in volume shrinkage and linear shrinkage, causing cracks or hollowing. 3) Improper maintenance: After the completion of construction, the ground was not maintained within the prescribed time or was not adequately watered for maintenance. When the concrete temperature is relatively high, pouring cold water for curing can also cause cracks. Note: When using only the diamond sand floor, it is recommended to use a maintenance agent (oily and film-forming effect) to maintain the floor. If the corundum is reinforced (or epoxy), water curing can be directly adopted. 4) The contraction joint was cut late, and cracks appeared due to thermal expansion and contraction. Under normal circumstances, it is advisable to cut the expansion joints 24 to 48 hours after the completion of the construction of the corundum floor. If it is too late, as the hardness of the floor gradually increases, the floor is prone to "cracking" and developing cracks during the cutting process. 5) If the spacing of the division joints is too large, cracks may also occur. Preventive measures 1) Strictly control the time of the first sprinkling of materials; 2) The concrete layer and the wear-resistant layer (corundum) are constructed simultaneously. 3) The curing time shall be no less than 14 days; 4) Reasonably control the cutting time; The spacing of the division joints should generally not exceed 6m*6m. Cause of formation 1) The roughening and polishing processes are rough. 2) Inadequate maintenance and insufficient maintenance time; 3) The spreading time of wear-resistant aggregates is not well controlled. Preventive measures 1) Use a grinding machine to thoroughly smooth, compact and roughen the ground for no less than three times, and use a floor trowel to thoroughly smooth and level the ground for no less than three times. 2) The curing time shall be no less than 14 days; 3) Strictly control the spreading time of wear-resistant materials. The timing of spreading wear-resistant materials varies as needed, depending on factors such as climate, temperature, and concrete mix ratio. Spreading too early will cause the wear-resistant material to sink into the concrete and lose its effect. If it is spread too late, the concrete will gradually lose its adhesive force due to solidification, preventing the wear-resistant material from fully bonding with it. The most convenient way to determine the time for spreading wear-resistant materials is to let your feet sink about 5mm when stepping on the ground, and then you can start the first spreading work. The moisture at the edges of walls, columns, doors and formwork disappears more quickly. It is advisable to prioritize the application of water to prevent the effect from being reduced due to water loss. 1. Local damage: Clean the damaged area thoroughly, soak it in water to moisten it, then repair it with a putty made of styrene-butadiene latex mixed with water and a hardener material that has screened out the aggregates. Finally, apply the styrene-butadiene latex mixed with water emulsion. 2. Large-scale damage: According to actual needs, lines can be drawn and sawn on the damaged area, the surface layer and part of the base layer can be chiseled off, then the area can be cleaned and moistened, the plain cement slurry can be swept, concrete can be poured, and finally the surface layer of the diamond sand hardener can be applied. 3. Floor peeling: The surface of the wear-resistant diamond sand floor curls and peels. Remedial measures: Cut and chisel off the peeling area (chiseling it into a pitted surface), spray water on the pitted area to moisten it, then apply repair mortar of the same grade as the concrete and press it down to level the ground. Finally, apply a curing agent. 4. Remedial measures for cracks in diamond sand floor: 1) Cracks in areas with requirements for anti-seepage, impact resistance and wear resistance on the surface should undergo surface treatment. 2) For cracks that can affect the integrity, strength, impermeability and steel bar corrosion of the structure, grouting treatment should be carried out. 3) For cracks that endanger the safe operation of buildings, in addition to grouting treatment, other reinforcement measures should also be taken when necessary. 4) Cracks that are sensitive to temperature should be treated when the crack opening is relatively large in the later stage of the low-temperature season. 5) Flexible materials must be used to treat active cracks.   Note: The parameters provided in this document are for reference only and are not mandatory.
