1.After the foundation treatment, commissioning of laser screed machine. According the original level point to make a fixed datum level point. Then laying plastic film, lashing steel mesh (according to the design needs), setting the edge mold; Set up laser emitter, according to the original level point to import the terrace elevation into the laser leveling machine.
2.Transportation of concrete: commodity concrete, transport to the construction site with concrete truck.
3.Elevation check: Check the elevation of the floor with a handheld receiver, import the elevation into laser leveling machine, and adjust the datum point on the leveling machine (±0.00).
4.Concrete paving: In the effective range of work head, artificial laying the concrete higher than elevation 1-2 cm (Specific height depends on concrete slump), then use the concrete laser leveling machine to complete the vibration, compaction, leveling operation.
5.Smoothing: When the concrete poured reaches the initial solidification, smoothing by concrete grinder, and then smoothing manually.
6.Maintenance: After the smoothing, do not move heavy objects on the concrete at least 7 days, and s should maintain a moist curing state, spray curing agent (According to design requirements). In order to achieve a good maintenance effect, the surface should be covered up, so that the isolation of concrete and external, in the maintenance period, before the strength of the concrete surface is not up to the requirements, it is strictly prohibited to stand or pass though.
7.Joint cutting: The cut should be according to the design requirements, after the completion of the surface treatment of the concrete surface, which is, before the final solidification of concrete, the gap spacing, width, depth to meet the requirements of the design and construction standards.
8.Others: Joint filling, protection, until the concrete reaches the available strength
