Quality control and consideration during construction of the concrete laser screed machine
1.Line and leveling the wall(column): Because the laser leveling machine can not touch the wall, 40cm area near the wall need to manually leveling, so we need to set the line, as a manual leveling reference.
2.Along the poured area in 24 hours to set the mold plate (recommended to use the steel mold), reserved dowel hole, and control the elevation of the mold plate to avoid the deviation of the joints in different level.
3.Along the wall, equipment foundation, column, and etc. to set the mold plate (thickness and position shall be determined according to the design requirements), set apart seams to avoid cracking of concrete surface.
4.Feeding: The conveying speed of concrete should be guaranteed a certain amount, and the feeding speed should be uniform, reduce pause intervals to prevent cold joints and affect the progress of the project. The concrete used for construction should keep the concrete slump and initial time consistent. The concrete slump should be controlled at 14~16 cm, the initial setting time should be controlled around 3 hours.
