Standard requirements for the flatness of concrete pavement

Can a laser leveler be used to make a "three super" floor? The "three super" floor is the ideal goal we have always wanted to achieve, but there is no way to achieve this standard with traditional operation methods. After all, the continuity of manual operations is not strong and it is very prone to operational errors. Can the laser leveling machine meet the standard of this "three super" floor?   The so-called "three supers" are super flat, super strong and super provincial. Since the 1990s, since the continuous promotion of "clear water concrete" (building) ground and colored wear-resistant (building) ground, after several years of research and exploration and continuous improvement, the process has been integrated through the concrete laser leveling machine. Perfect, the "three super" floors constructed with our company's series of products have reached the domestic or international first-class level.   1. Super flatness: Through the combination of concrete laser leveling machine and professional and precise personnel, the flatness level of (floor) ground can be raised from the current specification of 2 meters by 4mm to 2 meters by 2mm. , (Building) The level of the ground can reach within ±5mm/100m through the laser detection control of two laser sweepers and the imported laser leveling machine.   2. Super strength: Through the professional floor treatment equipment-single-disc and double-disc drive troweling machines several times, the (building) ground forms a real "clear water concrete" surface layer. It is also possible to sprinkle and add color hardening agent during surface construction or to brush liquid concrete sealing and curing agent on the surface of the original slurry "clear water concrete" to improve the surface strength again and truly realize the super strong surface. 3. Ultra-saving: Through the simultaneous construction of the concrete on the (floor) ground, the floor (ground) method is completed at one time, which not only saves the materials, labor, and machinery of the second method, but also avoids the damage caused by the second method. "Empty drums, cracks, peeling, sanding" and other common quality problems; it also reduces the load generated by the materials used in the secondary method between floors, saves the delay in the construction period caused by the secondary method, and greatly saves the construction period. The rental costs of turnover tools and various equipment caused by the elongation have saved a lot of costs and achieved economic benefits created by super-savings. After calculation, the secondary method is based on 6-8cm concrete, and the cost of labor, machinery, and materials required should be more than 40 yuan/m², even if the cost of finished product protection is deducted, the cost savings will be more than 30/m². By solving the concrete surface layer at one time, all the "common quality problems" caused by the second method are completely eliminated. The "three super" floor is flat, clean, dense, high-strength, one-layer overall, with reduced cost, shortened construction period, and absolute durability. It should be said that there is no better method to replace it, whether domestic or foreign.

  There are many specific application cases of laser leveling machines in municipal engineering. Here are some examples: 1. Highway construction: Laser leveling machines are widely used in highway construction, especially in the construction of highways and urban roads. They can help lay the road surface quickly and accurately, ensuring the flatness and stability of the road surface.   2. Municipal facility construction: Laser leveling machines can also be used in municipal facility construction, such as parking lots, squares, parks, etc. These places require large areas of concrete floors, and laser leveling machines can complete this work quickly and efficiently.   3. Subway construction: Subway construction also requires a large amount of concrete floors, so laser leveling machines are also widely used in this field. They can help lay subway platforms, tunnels and other infrastructure quickly and accurately.   4. Pipeline laying: Laser leveling machines can also be used for pipeline laying, especially the laying of large pipelines. They can help ensure the flatness and stability of pipelines and reduce the cost of subsequent maintenance.   5. Bridge construction: Bridge construction also requires a large amount of concrete floors, so laser leveling machines are also widely used in this field. They can help lay bridge panels and other infrastructure quickly and accurately.   In short, laser leveling machines are widely used in municipal engineering, which can help improve work efficiency and quality, reduce construction costs, and at the same time ensure the safety and stability of project quality.

  The construction machinery industry is becoming more and more mature, and various types of construction machinery are increasingly used in my country's consumer market, especially this year, concrete laser leveling machines are increasingly recognized by customers. As the leader of concrete laser leveling machines, the concrete laser leveling machines produced by Shandong Vanse Machinery can achieve large-scale construction. By solving the concrete surface layer at one time, all the "quality problems" brought by the secondary approach are completely eliminated. It truly realizes the "three super" floor of flatness, smoothness, density, high strength, one layer as a whole, reduced costs, shortened construction period, and absolutely durable. Shandong Vanse Machinery Concrete Laser Leveling Machine has several advantages over traditional laser leveling machines: Traditional leveling technology requires template support to control the elevation of the ground and pull the control line. The elevation error is large. The horizontality and flatness of the entire floor cannot be guaranteed. The laser point-to-point transmitter is used, which is suitable for large-area one-time paving. There is a laser measurement and control system to control the elevation in real time. There is no need to pull the line for leveling, and there is no need to support the side plate in the middle to control the ground elevation. Thus, the elevation error caused by the vibration of the formwork (channel steel) during the construction process is avoided, and the elevation error caused by the traditional manual block formwork is also reduced. The traditional process has a large number of construction workers, and it is necessary to support the formwork (channel steel), dot, and spread. It requires about 20 people. The construction area is 700 square meters per day. The total number of people using the concrete laser leveling machine is more than half less than that of the traditional process. It can be operated by one person. The construction area is 2500-3500 square meters per day, which greatly reduces the labor cost. Traditional construction technology, one day of formwork, one day of pouring, can only be skipped one by one, which has great limitations, cannot be operated continuously, and has poor integrity, which is easy to cause cumulative errors in construction joints. The concrete laser leveling machine is more efficient and integrated for a large area of ​​floor paving at one time. The completion of the entire floor makes the ground integrity better, which is completely impossible for traditional construction. The high-frequency vibrator of 4000 times per minute allows the leveling head vibrator to produce uniform high-frequency vibration, making the concrete floor more compact and uniform. Combining the above detailed comparison between ordinary leveling machines and Shandong Vanse Machinery's laser leveling machines, we can know why laser leveling machines are so popular now. In order to better and more effectively serve our customers, Shandong Vanse Machinery will continue to provide customers with safe and reliable products and more complete after-sales services.
