The application of pervious concrete floor in daily life

Concrete laser leveling machine – modern machinery for hardening large areas of cement, can effectively improve the hardness of the cement floor strength flatness. Nowadays, for the construction industry, the simple ground has higher requirements, so there are many companies will produce some machinery to help people to successfully complete the goal they want to achieve. The Vanse concrete laser leveling machine is made with the development of society. Its biggest effect is to help people maximize the strength of the cement after hardening or the levelness of the cement floor. It is an essential machine for modern construction industry. Concrete laser leveling machine is a machine that operates on large floors, or floors that require a very flat surface. After placing it on the ground, it can be leveled manually or automatically. The concrete floor is then hardened and leveled by means of high frequency vibration. This is an extremely efficient and modern way of working. The use of Vanse concrete laser leveling machine can reduce labor costs significantly. Although it costs about tens of thousands of dollars to buy a machine, it basically pays for itself in a few relatively small projects. And then the machine is still your own. This is a very worthwhile investment in modern machinery and equipment. Such a machine and equipment is through a variety of feedback mechanism and a variety of electrical equipment to collect signals. Then on the computer host for processing, and finally feedback to the machine itself and then through the computer analysis and processing to tell the answer to the machine. The Vanse concrete laser leveling machine has a very efficient operation. It can guarantee 24 hours a day non-stop work, and can reduce the length of time and labor costs. This is an essential piece of machinery for modern building construction.

The advent of the concrete laser leveling machine has brought not only high-quality and high-efficiency construction to the floor industry, but also a symbol of technological progress. Compared with the traditional artificial vibrating beam construction, the laser leveling machine has A qualitative leap forward, it is guided by a laser and is easy and convenient to operate. Working principle of concrete laser leveling machine The Laser Transmitter Generates Rotating Laser Light, And The Laser Receiver On The Leveling Machine Receives The Signal, Which Is Analyzed By The Laser Measurement And Control System, And The Deviation Will Be Fed Back To The Sensitive Computer Control System On The Leveling Machine, And The Left And Right Electric Push Rods Will Adjust The Position Of The Scraper. Height To Ensure Leveling Accuracy. Paving, Scraping, Vibrating, And Leveling The Floor Concrete, Mainly Laying The Concrete To An Elevation Higher Than The Design Requirements, And Vibrating And Leveling The Concrete. The floor-concrete laser leveling machine uses a scraper to take away the raised concrete and initially level it to reach the elevation required by the design. The two-wheel automatic walking system is adopted, and the vibration frequency is 4000 times/minute, which drives the entire vibration plate to vibrate the concrete together. The construction width of the floor concrete laser leveling machine is 2.5 meters. The leveling of the laser leveling machine does not need to pull the control line, nor does it need the side template to control the ground elevation, but is controlled by the laser measurement and control system on the leveling machine in real time. As long as the laser transmitter is not disturbed, no matter where the leveling machine moves, It can ensure that the overall elevation of the paved ground will not be affected. Super Flat: Through the combination of concrete laser leveling machine and professional and precise personnel, the flatness level of the (floor) ground can be raised from the current specification of 2 meters by 4mm to the standard of 2 meters by 2mm, and the (floor) ground The levelness can be achieved within the range of ±5mm/100m through the laser detection and control of two laser leveling devices and the leveling of the "Thunder Dragon" laser leveling machine. Super Strong: Through professional floor treatment equipment-single-disc and double-disc drive troweling machines several times, the (building) floor 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. Super Saving: Through the simultaneous construction of the (building) ground concrete, the building (ground) method is completed at one time, which not only saves the materials, labor, and machinery of the second method, but also avoids the "empty drums and cracks" caused by the second method. , 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 turnover caused by the extension of the construction period The rental fees of tools and various equipment save a lot of cost and achieve economic benefits created by super saving. 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, and the cost savings will be more than 30/m2 even after deducting the cost of finished product protection. 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.  

1. Material problems ○ Improper concrete mix ratio, too little cement content or too high mud content in sand will lead to insufficient ground strength and easy sanding. ○ The strength grade of the selected cement is not enough to meet the construction requirements. 2. Construction problems ○ Improper operation of the laser leveler, such as too fast leveling speed, leads to insufficient density of concrete. ○ Poor grasp of the finishing time, too early or too late finishing will affect the quality of the ground. ○ Inadequate maintenance, concrete lacks water during the hardening process, affecting the development of strength. 3. Environmental problems ○ Too high or too low construction environment temperature will affect the coagulation and hardening of concrete and increase the risk of sanding. ○ Low air humidity and too fast evaporation of water on the concrete surface can also easily lead to sanding. 1. Material aspects ○ Optimize the concrete mix ratio, ensure moderate cement content, and control the mud content of sand. ○ Choose cement with appropriate strength grade to ensure the strength requirements of the ground. 2. Construction ○ Operators should be proficient in the use of laser leveling machines, control the leveling speed, and ensure the density of concrete. ○ Accurately grasp the finishing time, generally finishing after the initial setting of concrete and before the final setting. ○ Strengthen maintenance, such as covering with plastic film and sprinkling water to keep the concrete surface moist, and the curing time is not less than 7 days. 3. Environmental ○ Adjust the construction time and maintenance measures according to the ambient temperature to avoid construction under extreme temperatures. ○ In a dry environment, the number of sprinkling water can be appropriately increased to maintain the humidity of the concrete surface.
