Discussion on floor construction technology using concrete laser leveling machine

  ✨   Taian Yuluoka new plant floor construction project: Yuluoka Mining Safety Engineering Co., Ltd.'s new plant floor project has a total area of about 18,000 square meters. The project uses large laser leveling machines and spreaders for integrated construction. A 10-centimeter-thick C30 concrete cushion is poured on the base layer, a double-layer 0.15mm PE film is laid, a 6# single-layer bidirectional steel mesh is erected, 20-centimeter-thick C30 concrete is spread and steel fiber is added, and wear-resistant aggregate is spread on the wear-resistant surface layer. The project has a tight schedule. With the stable performance of the laser leveling machine and the cooperation of the construction team, the construction was completed with high quality and recognized by the owner. ✨   Beijing Jeep Automobile Co., Ltd. increased its investment in the production of Mercedes-Benz cars: The main plant floor is a 220 mm thick integrally cast metal wear-resistant steel fiber floor with an area of 44,000 square meters. The owner requires that the surface flatness be checked with a 2-meter ruler and the allowable deviation be 3 mm, which is stricter than the national standard. China Construction First Engineering Bureau used a concrete laser screed machine for paving, and a complete set of ground construction technology with a dowel rod system. The actual construction period was only 33 days, which was 67 days shorter than the planned period for manual paving. All indicators such as ground flatness met the requirements, achieving good social and economic benefits. ✨   Flender Plant Phase III Project: This project is an industrial plant for the assembly and testing of transmission components manufactured by Flender, Germany. The steel fiber concrete metal wear-resistant floor area is 22,000 square meters, the ground thickness is 300 mm, and the ground flatness error is required to be controlled within 3 mm, and the bearing capacity is 15 tons/square meter. The construction party used a concrete laser screed machine for construction, and completed the ground construction in only 25 days, and all indicators met the standards. ✨   Anhui Chuzhou Chahe New Energy Industrial Park Phase II Project: This project was undertaken by China Construction Fifth Engineering Bureau Second Company. The plant mainly produces high-performance N-type TOPCon battery cells. There are AGV intelligent logistics robots running in the field, and the ground flatness requirements are extremely high. The project uses a large concrete laser leveler to construct the concrete floor, ensuring that the flatness deviation of the concrete molding surface is no more than 3 mm, and finally achieving a height difference of less than 1 mm within any 2-meter range. At the same time, the floor is in the form of steel fiber plus steel mesh to reduce the risk of floor sinking and cracking, meeting the factory's requirements for ground flatness and bearing capacity. ✨   New Xi'an Harmony High-Power Locomotive Maintenance Section Project: The industrial plant floor area is 55,000 square meters. The user unit has high requirements for ground flatness, crack resistance and wear resistance, and the surface flatness allowable deviation is 3 mm. The construction unit uses a laser leveler to pave the steel fiber concrete wear-resistant floor construction method. By setting up a force transmission rod system and adding steel fibers, the floor flatness and construction continuity are effectively guaranteed, the construction period is shortened, and the subsequent ground coating requirements are met.   Click the below to jump immediately!!!

    Cleaning power trowel blades after working with colored concrete requires extra care. If even a small amount of pigment is left behind, it can contaminate your next job, causing unwanted "ghosting" streaks on a natural or grey slab Here is a step-by-step guide to ensure your blades are thoroughly cleaned and protected for future use. Timing is the most critical factor. Once the pigment dries and bonds with the cement paste on the steel, it becomes incredibly difficult to remove Pressure Wash Immediately: As soon as the machine is off the slab, use a high-pressure washer (at least 3,000 PSI is recommended) to blast the underside of the spider and the blades Focus on Mounting Brackets: Pigment loves to hide in the "pockets" where the blades bolt onto the trowel arms. If these aren't cleaned, they can vibrate loose during the next job and drip old color into your fresh wet concrete If you were working with a reactive acid stain rather than integral color, you must neutralize the acid to stop the chemical reaction Neutralize: Mix a solution of baking soda and water or ammonia and water. Scrub: Use a stiff nylon brush to scrub the blades. This ensures no acid residue remains to react with or stain the next slab If the color has already started to harden on the blades, you'll need to step up to mechanical cleaning Abrasive Scouring: Use a pumice stone or a fine-grit sanding block to manually scour the blades. Avoid Grinders: Do not use a metal grinding disk unless absolutely necessary, as this can create burrs or uneven edges that will "scar" your next floor The "Sand Trick": Some operators run the trowel briefly on a pile of clean, damp sand. The friction acts like sandpaper and "polishes" the blades clean. (Note: Only do this if your machine can handle the torque without stalling) Steel blades rust almost instantly after being pressure washed . Apply Oil: Spray the blades with a light coating of WD-40 or a specialized form release agent . Wipe Down: Wipe off the excess. This prevents "flash rust" (orange dust), which can also stain your next concrete project . To make sure no spot is missed, use this checklist from the guide Component Cleaning Action Why? Blade Surface Scrub with stiff brush + Water Removes bulk pigment Blade Edges Sanding block / Pumice Removes "hardened" color buildup Bolts/Hardware High-pressure blast Prevents "bleeding" on next job Spider Arms Degreaser + Rinse Prevents grease/color drips If you frequently work with colored concrete, many professionals keep a dedicated set of "Color Only" blades and a separate set of "Grey Only" blades. Swapping blades is often cheaper and less time-consuming than trying to remove every speck of pigment from a single set Would you like to know the best neutralizing ratios for specific brands of acid stains?  Contact us NOW   Note: The parameters provided in this document are for reference only and are not mandatory.

In the field of concrete construction, concrete laser leveling machine (concrete laser leveling machine or concrete laser leveler) has become a key equipment to improve construction efficiency and quality. With the vigorous development of the construction industry, the demand for high-precision, large-area concrete construction continues to grow, and the application of concrete laser leveling machine is becoming more and more extensive. According to a market research report, the global concrete laser leveling machine market size is expected to reach US$1.76 billion in 2025, with an annual growth rate of approximately 11.4%. During long-term high-intensity use, how to extend the service life of the concrete laser leveling machine has become the focus of many users. This is not only related to the return on equipment investment, but also affects the smooth progress and cost control of construction projects.   After each operation with a concrete laser leveling machine, timely cleaning is essential. Since the equipment will be exposed to a large amount of concrete, mud and other impurities during operation, if it is not cleaned in time, these substances will adhere to the surface of the equipment and key components, accelerating component wear. For example, the body shell, leveling blade, vibrating device and other parts can be washed with a high-pressure water gun (but it should be noted that it is strictly forbidden to directly aim the water gun at the mesh part of the body to prevent water from entering the body and causing a short circuit) to remove the concrete residue and dust on the surface. For some stubborn stains that are difficult to wash off, use a soft cloth dipped in a neutral detergent dilution to wipe. Do not use strong alkali or strong acid cleaning agents to avoid corrosion of the paint and electroplating layer on the surface of the equipment, affecting the appearance and reducing the protective performance. Regularly check the connection and tightening of each component. During the operation of the equipment, the connecting bolts may become loose or even broken due to factors such as vibration and impact. For example, the connecting bolts of the frame, walking mechanism, laser transmitting and receiving device of the laser leveling machine should be carefully checked before and after each operation. If they are loose, tighten them in time. If the bolts are broken, they need to be replaced immediately. At the same time, check whether there is leakage in all parts of the equipment, including engine oil, coolant, hydraulic oil of the hydraulic system, etc. Once leakage is found, the cause should be promptly investigated and repaired to avoid problems such as poor lubrication and overheating of components due to oil leakage, which will affect the service life of the equipment. The timely replacement of wearing parts is the key to ensuring the continuous and stable operation of the equipment. For example, the leveling scraper, vibrator, tires (or rubber tracks) of the leveling machine will wear faster during frequent use. Generally speaking, the wearing parts should be checked after each use. If the wear exceeds the prescribed limit, they should be replaced immediately. Even if the wearing parts do not seem to be damaged during normal use, it is recommended to replace them every six months to ensure that the overall performance of the equipment is not affected. For example, a severely worn leveling scraper cannot effectively scrape the concrete, which will cause the ground flatness to decrease, and will also increase the workload of other parts of the equipment, accelerating the overall loss of the equipment.   In a high temperature environment, the concrete laser leveling machine faces many challenges. The engine is prone to overheating, resulting in power reduction and increased wear of parts. Therefore, when constructing in high temperatures in summer, first ensure that the engine cooling system is working properly. Before daily operation, check the coolant level and add it in time if it is insufficient; regularly clean the dust and debris on the surface of the radiator to ensure that the heat dissipation duct is unobstructed. When the engine temperature is too high, you should choose a cool area to stop and cool down. Do not rush to add cooling water. You need to let the engine idle for a while and add it after the temperature drops slightly to prevent the engine cylinder from cracking due to excessive temperature difference. At the same time, high temperature will also affect the performance of the hydraulic system. Check the hydraulic oil temperature frequently. If the oil temperature is too high, stop the machine for a rest to avoid long-term operation of the equipment at high temperatures. For example, in some southern regions during summer construction, if you do not pay attention to the heat dissipation of the equipment, it may cause the hydraulic system seals to age faster and leak oil, which will seriously affect the normal use of the equipment. High humidity environment can easily cause the metal parts of the concrete laser leveling machine to rust and corrode, especially when constructing in coastal areas or rainy seasons. To cope with high humidity environments, the equipment should be parked in a dry place and avoid being placed in the open air. If it is unavoidable to operate in a humid environment, anti-rust oil can be applied to the surface of the equipment, especially to parts that are prone to rust, such as the frame and chassis. At the same time, the electrical circuit should be checked regularly to prevent short circuit failures caused by moisture. For the battery of the equipment, it is necessary to keep it clean and dry, check the electrolyte level and density regularly, and replenish distilled water in time to ensure good battery performance. For example, if the laser leveling machine used for a long time in a high humidity environment does not pay attention to anti-rust treatment, it may cause problems such as frame rust and strength reduction in a short period of time, affecting the safety and service life of the equipment. Concrete contains alkaline substances. If the protection is not appropriate during long-term contact, it will cause corrosion to the components of the concrete laser leveling machine. For parts that are in direct contact with concrete, such as leveling blades, vibrating devices, etc., they can be made of corrosion-resistant materials or undergo special surface treatment to improve their resistance to alkali corrosion. After each operation, clean the equipment thoroughly to remove residual concrete and prevent alkaline substances from adhering to the surface of the equipment for a long time. In a high-alkaline environment, attention should also be paid to the lubrication system of the equipment, and lubricating oils and greases with good alkali resistance should be selected and replaced regularly to ensure that all moving parts are well lubricated and reduce the occurrence of failures caused by corrosion and wear. For example, in the construction of some industrial plant floors, due to the strong alkalinity of concrete, if effective protective measures are not taken, the key components of the equipment may be severely corroded in a short period of time, shortening the service life of the equipment.   Strictly operate in accordance with the rated working parameters of the concrete laser leveling machine to avoid operating in a condition that exceeds the equipment's bearing capacity. Overload operation will cause excessive pressure on the engine, hydraulic system, transmission components, etc., accelerate the wear of parts, and even cause equipment failure. For example, behaviors such as leveling thickness exceeding the maximum thickness specified by the equipment and forced operation on a site with a large slope will cause damage to the equipment. As an equipment manager, you should ensure that the operator is familiar with the equipment performance and operating procedures, and strictly prohibit illegal operations. Before construction, arrange construction tasks reasonably according to actual working conditions to ensure that the equipment operates stably within the normal load range. During the operation of the equipment, try to ensure smooth operation and avoid violent operations such as sudden acceleration, sudden braking and frequent steering. Sudden acceleration and sudden braking will cause the engine and transmission system to bear greater impact force instantly, which may easily cause damage to parts; frequent steering will aggravate the wear of tires (or tracks) and steering mechanisms. After starting the equipment, the engine should be allowed to idle for a period of time to allow all parts to be fully lubricated before operation. During the leveling operation, keep the equipment moving at a uniform speed to avoid speed fluctuations, which can not only ensure the construction quality but also reduce the wear of the equipment. For example, when driving a concrete laser leveler, smoothly controlling the throttle and steering wheel can effectively extend the service life of key parts of the equipment. The correct start and stop sequence also has an important impact on the service life of the concrete laser leveler. Before starting the equipment, check the environment around the equipment to ensure that there are no obstacles; check whether the liquid levels of fuel, engine oil, coolant, hydraulic oil, etc. are normal, and whether the indications of various instruments are normal. When starting, first turn the key to the power-on position, wait for the instrument self-check to complete, and then start the engine. After the engine is started, let it idle for a few minutes, observe the engine sound, vibration and whether the display of each instrument is normal, and then proceed to the next step after confirming that it is correct. When shutting down, first park the equipment on a flat and solid ground, lower the working device to the lowest position, and then turn off the engine. If the equipment is not used for a long time, the equipment should be sealed and maintained in accordance with the requirements of the equipment manual, such as draining fuel and coolant, lubricating and protecting key parts, etc. For example, the wrong starting method, such as forcibly starting the engine before the equipment completes the self-check, may damage the engine control system and affect the normal use of the equipment.   The hydraulic system is an important part of the concrete laser leveling machine, and regular maintenance is essential. Hydraulic oil will be contaminated and its performance will deteriorate during use, so the hydraulic oil should be replaced regularly. Under normal circumstances, the hydraulic oil should be replaced every 1,000 working hours or so. The specific replacement cycle can be adjusted appropriately according to the equipment use environment and the oil quality monitoring results. When replacing the hydraulic oil, use a clean container to hold the oil. The hydraulic oil must be filtered through the oil filter before adding it to the hydraulic oil tank to ensure that the oil is clean. At the same time, clean the hydraulic oil radiator regularly to ensure good heat dissipation and prevent the hydraulic system from malfunctioning due to excessive oil temperature. In addition, the replacement cycle of the hydraulic oil filter should also be appropriately shortened, generally 750 hours is appropriate. When replacing a new filter, check carefully. It is strictly forbidden to use a deformed, contaminated or rusted filter. For example, at some construction sites, due to the harsh environment, the hydraulic oil is easily contaminated by dust and impurities. If the filter and hydraulic oil are not replaced in time, it may cause blockage, leakage and other faults in the hydraulic system, seriously affecting the normal operation of the equipment. Regularly check the electrical system of the concrete laser leveling machine to ensure that all electrical components are firmly connected and the circuits are not damaged or aged. Check the performance of the laser transmitting and receiving device to ensure that the laser signal is stable and accurate. Start the engine once every two months, charge the battery, and run all hydraulic actuators, such as rotary hydraulic motors, telescopic cylinders, etc., to prevent battery loss and rust and jamming of hydraulic system components. Do not remove the battery from the machine at will to avoid the loss of internal software program failures in the equipment control. At the same time, pay attention to check the grounding of the electrical system to ensure that the grounding is good to prevent safety accidents caused by leakage. For example, if the electrical line is aging and damaged, it may cause a short circuit, causing a fire, and endangering the safety of equipment and personnel. Perform a comprehensive performance test on the concrete laser leveling machine every once in a while (such as half a year or a year). The test content includes key performance indicators such as leveling accuracy, work efficiency, engine power, and hydraulic system pressure. Through testing, potential problems with the equipment can be discovered in time, and targeted repairs and adjustments can be made. For example, if the leveling accuracy is found to be reduced, it may be due to laser system failure, wear of the leveling blade, or looseness of the mechanical parts of the equipment. It is necessary to check and repair them one by one to ensure that the equipment always maintains a good working condition and extends its service life.
