Because the laser transmitter is fixed after being set up, it can ensure that the construction of a large area of ground does not produce cumulative errors. During construction, the operator uses a hand-held laser receiver to detect the ground after the construction of the machine to ensure that the flatness error is within the controllable range.

Causes and treatment of concrete floor cracks 1. Introduction As an indispensable part of building structures, concrete floors are widely used in various construction sites. However, in actual use, cracks often occur in concrete floors, which not only affects the aesthetics of the floor, but also poses a potential threat to the integrity and safety of the structure. Therefore, it is particularly important to deeply study the causes of concrete floor cracks and take corresponding treatment measures. The formation of concrete floor cracks is a complex process involving many factors such as materials, design, construction, and environment. This paper aims to analyze the specific causes of concrete floor cracks, explore effective treatment methods and preventive measures, and provide theoretical support and practical guidance for crack control in actual projects. 2. Analysis of causes of concrete floor cracks ✔ Material factors The material selection of concrete floors is directly related to the generation of cracks. If the quality of raw materials such as cement, aggregates, and admixtures used is unqualified, or the mix ratio is improperly designed, it may lead to insufficient concrete strength and large shrinkage, thereby causing cracks. In addition, impurities, bubbles, and other defects added to concrete may also become the starting point of cracks. ✔ Design factors Improper design is also an important cause of concrete floor cracks. If the design load calculation is inaccurate, the structural layout is unreasonable, the ground thickness is insufficient or too thick, etc., the concrete floor may produce excessive stress concentration when subjected to force, resulting in cracks. ✔ Construction factors Improper operation during construction is also a common cause of cracks. For example, uneven vibration during concrete pouring leads to voids and stratification inside the concrete; failure to maintain in time after pouring causes shrinkage cracks due to excessive water loss during the hardening process; improper construction joint treatment forms weak links, etc. ✔ Environmental factors Environmental factors also have an important impact on the generation of cracks in concrete floors. For example, thermal expansion and contraction caused by temperature changes cause stress changes inside the concrete; humidity changes cause concrete to shrink or expand; foundation settlement, earthquakes and other natural disasters may also cause damage to the concrete floor and cause cracks. 3. Treatment measures for concrete floor cracks According to the different causes of concrete floor cracks, corresponding treatment measures need to be taken. The following are some common treatment methods: ✔ Surface repair method For cracks with smaller width and shallower depth, surface repair method can be used for treatment. Specific operations include cleaning the crack surface, applying repair materials such as ring gold resin to seal the cracks and restore the flatness and aesthetics of the ground. ✔ Filling method For cracks with larger width and deeper depth, the filling method can be used for treatment. First, clean the inside of the crack, and then use high-strength repair materials (such as epoxy mortar, polymer cement, etc.) to fill it to ensure that the filling is dense and tightly combined with the surrounding concrete. ✔ Pressure grouting method For cracks with larger width and deeper depth, the pressure grouting method can be used for treatment. The repair material is injected into the crack with a certain pressure through the grouting equipment, so that the material can be fully diffused and fill the crack space, thereby achieving the purpose of repair and reinforcement. ✔ Replacement method For cracks that are serious and affect structural safety, the replacement method may be required. That is, the damaged concrete part is excavated and new concrete is poured again to restore the integrity and structural safety of the ground. ✔ Structural reinforcement method While dealing with cracks, the overall structural performance of the concrete floor should also be considered. The crack resistance of the ground can be enhanced by adding steel mesh, increasing the thickness of the ground, and setting expansion joints. 4. Preventive measures In order to reduce the probability of cracks in concrete floors, preventive measures should also be taken from the aspects of design, materials, and construction: ✔ Rationally design the floor structure and thickness to ensure that the use requirements and load conditions are met. ✔ Select high-quality raw materials and strictly control the mix ratio to ensure the quality of concrete. ✔ Strengthen the management of the construction process to ensure the pouring, vibration, maintenance and other process operations are standardized. ✔ Fully consider the impact of environmental factors on the concrete floor and take corresponding measures to prevent it. 5. Case analysis In order to better illustrate the causes and treatment measures of cracks in concrete floors, this paper selects a real engineering case for analysis. During the construction process of this project, cracks appeared on the ground due to uneven vibration and untimely maintenance. After on-site investigation and cause analysis, the construction unit adopted the filling method and strengthened maintenance measures to deal with the cracks, and strengthened the management of the subsequent construction process, effectively preventing similar problems from happening again. 6. Technology development trend With the advancement of science and technology and the continuous accumulation of engineering practice, the technology for handling cracks in concrete floors is also developing. In the future, we can expect the emergence of more efficient, environmentally friendly and intelligent crack handling technologies. For example, using nondestructive testing technology to accurately identify and locate cracks; using new repair materials to improve the repair effect and durability; using intelligent monitoring systems to monitor and warn concrete floors in real time, etc. The application of these technologies will further improve the efficiency and accuracy of concrete floor crack treatment, and provide strong support for ensuring project safety and performance. 7.
