Quality Control And Precautions In The Construction Process Of Concrete Laser Leveling Machine Concrete laser leveling machine is an indispensable equipment in construction machinery, and it is indispensable in the construction of building floors. Doing the following points well during construction will have a great effect on improving the productivity and construction quality of the concrete laser leveling machine. 1. Line setting and leveling on the wall (column): Since the laser leveling machine on the side of the wall cannot be touched, manual leveling is required within 40 cm along the side of the wall (formwork), so line setting is required as a reference for manual leveling . 2. Set up formwork (steel formwork is recommended) along the scope of pouring on the same day, reserve holes for dowel rods, and control the elevation of the formwork to avoid large deviations in the flatness of the joints of different warehouses. 3. Set templates or thin sheets along the walls, equipment foundations, columns, etc. (thickness and position are determined according to design requirements), and leave separation joints to avoid cracking of the concrete floor. 4. Laser transmitter erection: (1) The laser transmitter should be erected at the best position, and there should be no clips to be tightened; (2) There should be no large vibration sources around; (3) Reasonably set the concrete paving direction and leveling direction, and determine a reasonable construction walking route of the leveling machine to avoid leveling blind spots. (4) Feeding: The concrete conveying speed should be guaranteed to be a certain amount, and the feeding speed should be uniform, and the pause interval should be reduced in the middle to prevent cold joints and affect the progress of the project. The slump and initial setting time of the concrete sent to the site each time must be consistent. The concrete slump should be controlled at 14~16cm, and the initial setting time should be controlled at about 3 hours. Note: Some content of this quality control is for reference only, and the actual construction should be formulated according to the floor design requirements and the characteristics of the construction site.

Slump: 120~180mm (about 150mm is appropriate) Applicable scenarios: Applicable to laser leveling machine or paver construction to ensure that the fluidity of concrete meets the requirements of mechanical paving and vibration. High slump: 180~220mm (when adding water reducer) Applicable scenarios: Complex reinforcement structure or high temperature dry environment, it is necessary to improve the fluidity of concrete to avoid segregation. Low slump: 80~120mm (dry hard concrete) Applicable scenarios: Construction with slipform paver, or projects with high early strength requirements.   Laser leveling machine: requires a higher slump (120~180mm) to facilitate mechanical vibration and leveling. Slipform paver: The slump should be strictly controlled at 80~120mm to avoid deformation of the structure due to excessive fluidity. Hot and dry weather: The slump can be appropriately increased (+20~30mm) to reduce the slump loss caused by water evaporation. Low temperature or rainy season: The slump can be appropriately reduced (-10~20mm) to prevent concrete segregation. When the coarse aggregate particle size is large and the grading is poor, the slump needs to be increased to ensure workability. Adding water reducer can reduce the water-cement ratio and improve strength while maintaining the slump.   Each truck of concrete needs to be tested for slump before unloading. If the deviation exceeds ±20mm, it needs to be adjusted (such as adding admixtures or secondary mixing). The mixing and pouring of concrete must be completed before the initial setting (usually ≤2 hours) to avoid slump loss due to too long time. Slump is too large: it is easy to cause bleeding and segregation, which can be improved by adding fly ash or reducing the water-cement ratio. Slump is too small: poor fluidity, it is necessary to add water reducer or increase the water consumption appropriately (need to be verified by the laboratory).   "Technical Specifications for Construction of Highway Cement Concrete Pavement" (JTG/T 3650-2020): The recommended slump is 100~180mm, which is adjusted according to the construction machinery. "Concrete Structure Engineering Construction Quality Acceptance Code" (GB 50204-2015): The slump detection frequency is required to be no less than once every 100m³. Reasonable control of slump can ensure the construction quality, durability and appearance smoothness of concrete pavement. The specific parameters need to be determined in combination with design requirements, construction technology and environmental conditions.
