  Laser leveling concrete wear-resistant floor refers to the use of laser leveling machines to perform high-precision and rapid leveling operations on concrete, thereby obtaining a concrete wear-resistant floor that meets high standards in terms of flatness, levelness, density and strength.   The concrete laser leveling machine uses laser as the reference plane, and emits rotating laser through the laser transmitter. The laser signal is captured by the laser receiver on the leveling machine. The received signal is deeply analyzed by the laser measurement and control system, and any deviation will be accurately identified and fed back to the highly sensitive computer control system on the leveling machine. Based on this feedback information, the leveling machine will intelligently adjust the height of the scraper or leveling head to ensure the accuracy of the leveling operation. At the same time, the hydraulically driven vibration motor drives the vibration plate to vibrate the concrete to further compact the ground.   (1) Construction preparation Material preparation: Ensure the quality of concrete materials. Polycondensate high-efficiency water reducer can be added to reduce the risk of cracking. At the same time, prepare the required wear-resistant aggregates, interface agents and other materials. Equipment preparation: Transport and place laser leveling machines, trowels, trimmers, vacuum cleaners and other equipment to the designated location on site, and perform maintenance work to ensure that the equipment is in good standby condition. Base treatment: Mill the base to increase the adhesion between the leveling layer concrete and the base. Clean the surface of the concrete base plate and use a high-pressure water gun to thoroughly rinse the floor surface. Sweep mortar or apply special interface agent as needed. (2) Formwork setting and steel bar laying Formwork setting: Set the formwork according to the design requirements, ensure that the formwork support is on the same horizontal line as the elevation, and use a special formwork frame to set it at an inclined angle to facilitate subsequent construction. Rebar laying: Adding steel bars to concrete can effectively increase the tensile strength of concrete and prevent cracking. The steel mesh should be placed 20mm~30mm away from the floor surface, which not only increases the tensile strength of concrete but also protects the surface from cracks. (3) Concrete paving and laser leveling Concrete paving: The mixed concrete is pumped and spread on the crushed stone base. The paving speed should be appropriate, and manual leveling should be assisted quickly. Ensure that the concrete construction thickness meets the design requirements. Laser leveling: Use a laser transmitter to determine the height of the concrete paving construction, and use a laser leveling machine to perform leveling operations. During the leveling process, one person should be responsible for moving the laser leveling machine, and two people should be responsible for the front-end auxiliary leveling to ensure that the concrete surface remains at the designed height (4) Initial grinding and slurry breaking and throwing wear-resistant aggregates Initial grinding and slurry breaking: When the concrete is initially set, use a single-disc and double-disc trowel to repeatedly rub and level the concrete slurry. The best time is when there are no clear footprints left by people on the concrete. Spreading wear-resistant aggregate: Spread the specified amount of wear-resistant material evenly on the surface of the concrete just after the slurry is broken. Special materials can be considered as specific conditions and spread more than twice. After each spreading, use a trowel to grind and compact the aggregate. Finishing and maintenance Finishing operation: Depending on the degree of hardening of the concrete, perform at least three trowel operations without a disc. The speed and angle of the trowel should be adjusted according to the degree of hardening of the concrete. The corners can be manually scraped. Maintenance: After the construction is completed, it takes more than 28 days to maintain. Sprinkle water for maintenance and lay soil cloth to reduce water evaporation and keep the wear-resistant floor after construction in water. (5) Cutting expansion joints and subsequent treatment Cutting expansion joints: After the concrete has been sprinkled with water for a certain period of time (such as 24 hours), cut the expansion joints according to the design requirements. The setting of expansion joints should take into account the expansion and contraction space of concrete to prevent cracking. Subsequent treatment: Clean and fill the expansion joints after cutting to ensure the beauty and practicality of the floor.   The construction requirements of laser-leveled concrete wear-resistant floor are strict, covering material selection, construction equipment, construction process, construction environment and other aspects.

Check whether the laser transmitter and receiver are working properly, ensure that the laser signal has no dead corners, and can monitor and control the ground elevation in real time. Base treatment: The base should be flat, solid, free of oil and debris to ensure good bonding between the concrete and the base. After the base is treated, it should be inspected and accepted, and the next step can be carried out only after it is qualified. ② Matters needing attention during construction Concrete paving: The minimum hourly feeding speed of concrete should be determined according to the ground thickness and pouring area to avoid cold joint problems. When manually assisted leveling, attention should be paid to the uniform distribution of concrete to avoid large piles falling. Laser leveling: When using the laser leveling machine, the measured height of the vertical pole should be accurate to ensure the leveling accuracy. During the leveling process, the laser leveling machine should be integrated with the paving machine to maintain good rigidity and avoid excessive vibration affecting the construction quality. Operators of laser leveling machines need to undergo professional training and be familiar with the performance and operating procedures of the equipment. Spreading of wear-resistant bone materials: Wear-resistant bone materials should be spread evenly in batches, and after each spreading, they should be compacted and polished with a trowel to ensure wear resistance and flatness. Finishing and maintenance: The finishing operation should be polished multiple times according to the hardening of the concrete to ensure that the floor is smooth and flawless. The floor should be kept moist during maintenance, and a maintenance blanket, non-woven fabric or film should be used to cover and moisturize the floor to prevent the concrete from drying out too quickly and causing cracking. ③ Precautions after construction Cutting and expansion joint treatment: After the construction of the laser-leveled concrete wear-resistant floor is completed, the expansion joint should be cut in time to prevent the concrete from cracking due to expansion and contraction. Professional personnel should be assigned to the cutting operation to ensure that the cutting depth and spacing meet the design requirements. Finished product protection: Guardrails and warning signs should be set up for the completed floor area to prevent people from stepping on and contaminating. Use maintenance blankets, non-woven fabrics or films to cover and protect the floor from external damage.
