Maintenance of underground parking lot floor

    "Technology brings development" is true. Compared with more traditional floor machinery and equipment, the emergence of laser leveling machines is all the rage. As a mechanical equipment, it can effectively help our floor industry construction workers shorten the construction period and improve the construction quality. Today, let's take a look at the advantages of the DZ25-2 laser leveling machine, which makes us so fascinated by it. The unique hand-held and dual control modes allow our construction workers to control freely and flexibly. Only one person is needed to operate this machine for construction. The two wheels move independently, which is convenient and flexible. Because it is equipped with an electric-driven two-wheel walking system, the wheels can move independently and do not affect the construction of the front leveling head. We can manually control the forward, backward, steering and travel speed of the wheels, which is very convenient to move. The leveling head is composed of scrapers, vibrators, vibration plates and other components, and all materials are made of magnesium alloy used in aviation. The integrated leveling head integrates multiple processes such as leveling, leveling, and vibration, and is completed by the machine at one time. It is both efficient and labor-saving. The high-frequency vibrator of 4,000 times per minute ensures a more stable construction quality. The uniform high-frequency vibration of the vibration plate of the leveling head makes the concrete floor dense and avoids cracking of the floor caused by deformation. It can effectively solve the problems of hollowing, peeling, cracking and inequality of the floor. Some people may ask, what is the magic of the "laser" of the laser leveling machine? Don't worry, the magic will of course be put at the end! Don't you think so? The laser transmitter of the DZ25-2 laser leveling machine is arranged independently, so that we can ensure the consistency of the ground elevation when paving a large area as a whole, without any error. When carrying out large-scale block construction, it can also reduce construction joints, greatly reducing the cost of later maintenance of the ground. Concrete laser leveling machine The most magical laser measurement and control system can automatically control the elevation. This is because the design elevation of the top surface of the floor is automatically controlled by the laser machine computer, which ensures the flatness of the higher ground. It can directly achieve accurate leveling on the concrete layer. The flatness of the ground is not affected by the vibration of the construction template. There is no need to support the template in the middle, which reduces the input of labor and materials, reduces the construction procedures, and speeds up the construction progress. Some people will ask, what is the construction efficiency? 300 square meters of construction area per hour, about 3,500 square meters of construction work per day, don't you like such construction efficiency? I can't wait to get a few machines and put them into construction as soon as possible.

Assessing the smoothness of concrete pavements through quality testing ♢♢♢♢ Introduction The smoothness of concrete pavement is one of the important indicators for evaluating its construction quality and performance. Good flatness not only improves the aesthetics of the road, but also helps ensure driving safety and extend the service life of the road. Therefore, it is crucial to inspect and evaluate the flatness quality of concrete pavement. This article aims to discuss how to evaluate the smoothness of concrete pavement through quality testing, including testing methods, evaluation standards, and improvement measures. ♢♢♢♢ Method for testing the flatness of concrete pavement 1. Ruler method The ruler method is a common method for evaluating the flatness of concrete pavement. This method uses a ruler placed on the road surface and determines the smoothness of the road surface by observing the gap between the ruler and the road surface. The larger the gap, the worse the smoothness of the road surface. The ruler method is simple and easy to implement, but it is greatly affected by human factors and requires experienced inspectors. 2. Laser scanning method The laser scanning method is an advanced flatness detection method. It uses the principle of laser ranging to scan the road surface with high precision through a laser scanner to obtain the three-dimensional topography data of the road surface. Through data processing and analysis, the smoothness index of the road surface can be obtained. The laser scanning method has the advantages of high precision and high efficiency, and is suitable for large-area, high-precision road surface smoothness detection. 3. Level method The level method uses a level to measure the elevation of each point on the road surface, and determines the smoothness of the road surface by comparing the elevation differences between adjacent points. This method has high measurement accuracy, but requires more measurement points and complex calculation processes, and the detection efficiency is relatively low. ♢♢♢♢ Evaluation criteria for concrete pavement smoothness The evaluation standards for concrete pavement flatness are usually formulated according to relevant national and regional specifications. Generally speaking, the evaluation criteria include the following aspects: 1. Maximum gap The maximum gap refers to the maximum gap value between the ruler and the road surface in the ruler method detection. According to the specification requirements, the maximum gap value should be within a certain range. If it exceeds this range, the smoothness of the road surface will be deemed not to meet the requirements. 2. Smoothness index Smoothness index is a comprehensive index obtained by counting and processing the elevation data of multiple measuring points on the road surface. This index can comprehensively reflect the smoothness of the road surface and is an important basis for evaluating the smoothness of the road surface. 3. Driving comfort Driving comfort refers to the smoothness and comfort of a vehicle when driving on the road. A well-smooth road surface should ensure the smoothness and comfort of vehicle driving and reduce vehicle wear and driver fatigue. ♢♢♢♢ Measures to improve the smoothness of concrete pavement 1. Optimize construction technology: Construction technology is one of the important factors affecting the smoothness of concrete pavement. Optimizing construction techniques, such as reasonably controlling the water-cement ratio and using efficient vibration equipment, can improve the compactness and uniformity of concrete, thereby improving the smoothness of the road surface. 2. Strengthen construction quality control: Quality control during the construction process is the key to ensuring the smoothness of concrete pavement. Construction units should strictly carry out construction in accordance with design requirements and technical specifications, and strengthen control over raw materials, construction equipment, construction techniques, etc., to ensure that construction quality meets requirements. 3. Deal with pavement defects in a timely manner: During and after construction, pavement defects, such as honeycombs, pitted surfaces, cracks, etc., should be discovered and dealt with in a timely manner. For minor defects, repair measures can be taken to deal with them; for serious defects, rework should be carried out to ensure the smoothness and flatness of the road surface. 4. Strengthen care and maintenance. Concrete pavement will be affected by natural factors and traffic loads during use, causing the smoothness of the pavement to gradually decrease. Therefore, it is crucial to strengthen the maintenance and maintenance of road surfaces. Regular cleaning of the road surface, timely repair of damaged parts, and preventive maintenance can extend the service life of the road surface and maintain its smoothness and smoothness. ♢♢♢♢ Summary and Outlook The flatness assessment of concrete pavement is a complex and important task involving multiple testing methods and evaluation standards. By rationally selecting testing methods and applying evaluation standards, the flatness of concrete pavement can be accurately evaluated, and corresponding improvement measures can be taken to improve the performance of the pavement. With the continuous advancement of science and technology and the emergence of new detection technologies, the evaluation method of concrete pavement flatness will be more accurate and efficient. In the future, we can look forward to the application of more intelligent and automated testing equipment and methods in concrete pavement flatness assessment, providing strong support for improving pavement construction quality and performance.
