Supporting Facilities And Technical Support For Concrete Laser Leveling

Tell you how effective the concrete laser leveling machine is! Many consumers are still hesitating whether they should buy a concrete laser leveling machine, because they have no concept of the construction effect of the equipment. Today we will introduce the use effect of the equipment. First of all, the biggest feature of this equipment is that it is fast, and the time-consuming is 1/10 of manual work, which is enough to make many construction teams excited; secondly, it is flat, and the ground level error after paving is small , is almost negligible. 1. Requirements for concrete and formwork ① Concrete:  Concrete must be produced, conveyed or pumped to the flooring site by a commercial concrete production plant. ② Concrete specifications: C25~C30 concrete, the strength of which is not less than 25MPa in 28 days, according to the design requirements. ③ Water-cement ratio: N o more than 0.5, no water can be added during the feeding process. ④ Cement: Use ordinary Portland cement with a grade of not less than 42.5. ⑤ Aggregate: Well-graded aggregate should be used. Crushed granite or pebbles are used as coarse aggregate, and the maximum diameter is not more than 25mm. The fine aggregate is clean river sand with a fineness modulus of 2.4-2.7. ⑥ Concrete mix ratio: The amount of cement is not less than 350Kg/m3. In order to avoid surface quality problems, the sand rate should be controlled at 35% to 40%. ⑦ Concrete slump: 14±2cm, maximum 16cm. ⑧ Setting time: The initial setting time should be controlled within 3-5 hours. In order to avoid the excessive deviation of the surface elevation affecting the joints, the formwork should be steel formwork. The height of the formwork should be controlled within +0 and -2mm, and the steel formwork should be within 1-1.2 meters from the surrounding walls. 2. Construction cooperation requirements ① The concrete feeding speed should be determined according to the ground thickness and pouring area to determine the minimum hourly feeding speed. For a floor with a thickness of 200 mm, if the width of one-time pouring reaches 40 meters, the minimum feeding speed should reach 40 cubic meters per hour, otherwise there will be cold joint problems, which will affect the quality of ground construction. ② Manually coordinate the concrete sent to the platform, and workers need to remove it as soon as possible and roughly level it. In addition, the areas around the formwork, walls, columns, trenches, equipment foundations, floor drains or around pipelines that cannot be leveled require manual cooperation for local leveling. Generally, 3-4 workers are required to cooperate with the construction (provided by Party A). ③ Other precautions In order to ensure the flatness of the ground, attention should be paid to: 1) The slump of concrete sent to the platform must be consistent each time. 2) Ensure that the concrete feeding speed reaches 40 cubic meters per hour or above, and the initial setting time of each batch of concrete must be consistent. 3) Ensure that the formwork elevation is accurate and cannot be disturbed during construction. 4) Environmental cooperation. The concrete floor that has just been constructed cannot be exposed to sunlight, wind, rain, etc. that are unfavorable to concrete health. ④ Other requirements: A. In order to avoid random cracks in the floor, the cutting time of shrinkage joints should be carried out as early as possible (within 24 hours). B. At the same time as the construction of the laser leveling machine, there should be no electric welding machines on site, and no reflective objects (such as glass windows). C. The foundation must reach a certain hardness to ensure that the laser leveling machine does not collapse when working on the ground. D. The height of the ground in the factory building shall be calibrated by Party A, and the points must be evenly distributed, and there must be no error in the levelness. E. Pouring concrete must be operated according to the requirements of Party B's technicians.

How to deal with existing cracks in diamond wear-resistant flooring Diamond wear-resistant flooring has been widely used in industrial plants, warehouses, parking lots and other places due to its high wear resistance, high strength and beautiful appearance. However, during use, cracks may appear in the floor due to the influence of various factors such as materials, construction, and environment. Cracks not only affect the aesthetics of the floor, but also the durability and performance of the floor. Therefore, for cracks in diamond wear-resistant flooring that have already appeared, appropriate treatment methods must be adopted. This article will combine actual cases to explore how to deal with cracks in diamond wear-resistant flooring that have already appeared. 1. Crack type and cause analysis Before dealing with cracks in diamond wear-resistant flooring, it is necessary to first analyze the types and causes of cracks. Crack types mainly include transverse cracks, longitudinal cracks, mesh cracks and irregular cracks. The causes of these cracks are varied, and may involve various factors such as material quality, construction technology, temperature changes, humidity changes, foundation settlement, etc. Therefore, different treatment methods are needed for cracks of different types and causes. 2. Preparation before crack treatment Before treating the cracks in the diamond wear-resistant floor, a series of preparations need to be carried out. First, the cracks need to be inspected and recorded in detail, including the length, width, depth and distribution of the cracks. Secondly, it is necessary to clean up the debris and oil in the cracks to ensure that the surface of the cracks is clean and dry. Finally, according to the type and cause of the cracks, a suitable treatment plan is formulated. 3. Crack treatment method ☑ Filling method For cracks with smaller width and shallower depth, the filling method can be used for treatment. First, select the filling material suitable for the floor material, such as elastic caulking agent, polyurethane sealant, etc. Then, apply the filling material evenly on the crack surface to ensure that the filling material fully fills the crack. Finally, use a sharp plate to level the excess filling material so that it is flush with the floor surface. The filling method is simple to operate and low in cost, and is suitable for treating minor cracks. ☑ Expansion method For cracks with larger width and deeper depth, the filling method may not be effective. At this time, the expansion method can be used for treatment. First, use a cutting machine or a drilling machine to widen and deepen the profile joint so that the profile joint forms a V-shaped groove. Then, fill the special floor repair material into the V-shaped groove to ensure that the repair material fully fills the entire crack. Finally, use a scraper to scrape off the excess repair material and maintain it until the repair material is completely solidified. The crack expansion method can effectively improve the quality of crack repair, but the operation is relatively complicated and the cost is high. ☑ Pressure grouting method For cracks with larger width and deeper depth, the crack position is more special, and it is difficult to expand the crack, the pressure grouting method can be used. First, set a grouting hole at one end of the crack and an exhaust hole at the other end. Then, use a grouting machine to inject special grouting materials (such as epoxy resin, polyurethane, etc.) into the crack through the grouting hole. During the grouting process, the grouting pressure and grouting speed are controlled to make the grouting material fully fill the crack. Finally, after the grouting material is solidified, the crack surface is polished and processed. Pressure grouting can effectively improve the density and strength of crack repair, but the operation is difficult and requires professional equipment and personnel. 4. Maintenance and precautions after crack treatment ☑ Maintenance After the crack treatment is completed, the repaired part needs to be maintained. During the maintenance period, heavy objects should be avoided from rolling over and sharp objects should be avoided from scratching the repaired part to avoid affecting the repair effect. At the same time, the repaired part should be kept dry and clean to avoid water or other liquids from penetrating into the repaired part. The maintenance time is generally determined by the curing time of the repair material and environmental conditions. ☑ Precautions (1) When dealing with cracks, the appropriate treatment method should be selected according to the type and cause of the cracks. Avoid blind treatment or inappropriate treatment methods that may cause crack expansion or poor repair effect. (2) When selecting repair materials, ensure that the performance of the repair materials matches the original floor materials. Avoid using inferior or incompatible repair materials that may cause problems such as falling off and cracking at the repaired part. (3) When dealing with cracks, safety protection measures should be taken. Avoid dust and splashes generated during the treatment process that may cause harm to personnel and the environment. At the same time, relevant safety operating procedures must be followed to ensure the safety and stability of the construction process. 5. Case Analysis After a period of use, the diamond wear-resistant floor of a large industrial plant had multiple horizontal cracks and mesh cracks. After a detailed inspection and cause analysis of the cracks, it was found that the cracks were mainly caused by factors such as temperature changes, humidity changes and foundation settlement. In response to this situation, the expansion method was adopted for treatment. First, the cracks were widened and deepened to form a V-shaped groove. Then, a special floor repair material was used to fill the V-shaped groove to ensure that the repair material fully filled the entire crack. Finally, the repaired part was maintained and polished. After treatment, the cracks were effectively repaired, and the flatness and aesthetics of the floor were restored. 6. Summary and Outlook The treatment of diamond wear-resistant floor cracks is a complex and important task. By analyzing the types and causes of cracks and selecting appropriate treatment methods, the quality of crack repair and the performance of the floor can be effectively improved. At the same time, attention should be paid to safety protection and maintenance work during the crack treatment process to ensure the safety of the construction process and the durability of the repair effect. With the continuous advancement of science and technology and the emergence of new materials, the crack treatment technology of diamond wear-resistant floor will be more mature and perfect in the future. For example, advanced non-destructive testing technology can be used to accurately measure and locate cracks to improve the accuracy and efficiency of treatment: more excellent repair materials can be developed to improve the strength and durability of the repaired parts: more environmentally friendly and energy-saving crack treatment methods can be explored to reduce the impact on the environment during the treatment process. In addition, in addition to crack treatment, daily maintenance and care are also the key to keeping diamond wear-resistant floor in good condition. The floor should be cleaned and maintained regularly, and small cracks and damage should be discovered and treated in time to prevent them from expanding and deteriorating. At the same time, care should be taken to avoid collisions with heavy objects and scratches with sharp objects to avoid damage to the floor. In summary, the treatment of diamond wear-resistant floor cracks is a systematic project, which requires comprehensive consideration of the types, causes, treatment methods and daily maintenance of cracks. Only by scientific analysis, reasonable treatment and careful maintenance can the long-term use effect and aesthetics of diamond wear-resistant floor be ensured. In practical applications, we also need to constantly sum up experience and lessons, combine specific engineering practices, and explore crack treatment methods that are more suitable for different environments and needs. At the same time, strengthening the training and education of relevant personnel and improving their professional skills and operation level are also important measures to ensure the quality and effect of crack treatment. In the future, with the continuous advancement of science and technology and the continuous development of floor materials, we have reason to believe that the treatment of diamond wear-resistant floor cracks will become simpler, more efficient and more reliable. This will provide safer, more beautiful and more durable floor solutions for industrial plants, warehouses, parking lots and other places, and provide a more comfortable and convenient environment for people's production and life. In the process of crack treatment, in addition to the traditional methods such as the expansion method and pressure grouting method mentioned above, some new technical means can also be tried. For example, using drones or robots to automatically detect and identify cracks, accurately determine the location and size of cracks through image recognition technology, and improve processing efficiency and accuracy. In addition, it is possible to consider the use of new self-healing materials that can automatically fill and repair cracks when they occur, thereby extending the service life of the floor. At the same time, with the continuous improvement of environmental awareness, attention should also be paid to environmental protection and sustainable development in the process of crack treatment. Select repair materials with excellent environmental performance, reduce waste and pollutants generated during the treatment process, and ensure that the impact of the treatment process on the environment is minimized. In addition, energy-saving technologies should be actively promoted and applied to reduce energy consumption in the treatment process and improve resource utilization efficiency. In short, the treatment of cracks in diamond wear-resistant floor is a field that is constantly developing and improving. Through continuous exploration of new technical means, improving treatment efficiency and accuracy, and focusing on environmental protection and sustainable development, we are expected to provide more high-quality, efficient and environmentally friendly solutions for the treatment of cracks in diamond wear-resistant floor. This will bring a better experience to industrial production and people's daily life. Before ending this article, it should be emphasized that for the treatment of cracks in diamond wear-resistant floor, prevention is always better than treatment. Therefore, in the design and construction stages, factors such as material selection, construction technology, and foundation treatment should be fully considered to avoid the occurrence of cracks as much as possible. At the same time, during use, the maintenance and care of the floor should be strengthened, potential problems should be discovered and dealt with in a timely manner, and the long-term stable operation of the floor should be ensured. Looking to the future, with the advancement of science and technology and the development of floor materials, we look forward to seeing more innovative solutions applied to the treatment of cracks in diamond wear-resistant floor. This will bring a broader development prospect to the flooring industry and make greater contributions to the sustainable development of society.
