Detailed explanation of concrete laser leveling machine pouring leveling construction and leveling control matters
1. Preparation
1.1 After the base layer is processed, the equipment of the laser paver is debugged, and the fixed reference level point is drawn according to the original level point; the non-woven fabric is laid, the side formwork is supported, the laser transmitter is erected, and the ground level is introduced according to the original level point. Laser leveling machine.
1.2 Conveying concrete
Commercial concrete is used, and the commercial concrete is transported to the entrance and exit of the garage by tank truck, and then transported to the construction site by a three-wheel dump truck.
1.3 Standard calibration
Use a hand-held laser receiver to check the elevation of the floor, introduce the elevation into the laser paver, and adjust the reference point (±0.00) on the leveling machine.
2. Concrete paving
Pouring steps:
(1) After the formwork is supported, the warehouse should be cleaned one day in advance before pouring concrete, rinsed and soaked with water. When pouring is approaching, drain the open water and sweep the cement slurry or interface agent. At this time, no obvious water accumulation is strictly prohibited. If there is, it must be resolutely removed before paving concrete.
(2) After the concrete is put down, it should be preliminarily leveled, and the leveling height should be 3 cm thicker than the elevation. Then level it with a laser paver. The corners that cannot be leveled can be leveled with a gasoline leveler or manually.
(3) When the warehouse near the wall is being poured, after the leveling machine walks over, it must be scraped with a scraper in time. and so on.
(4) For areas where concrete mixer trucks cannot be driven to the site, tractors should be used to transfer concrete. After the pouring is completed, the floor finishing construction begins when the concrete is initially set.

3. During construction, the laser signal received by the receiver of the laser paver (frequency of 10 times per second) automatically adjusts the elevation in real time to ensure that the construction elevation is always at the set standard. 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.
4. During the construction, the operator uses a hand-held laser receiver to detect the ground after the machine is constructed, and again ensures that the flatness error is within the controllable range.
