Concrete paving
In the laser leveling machine leveling the scope of the first effective construction, the first artificial concrete to flat to flat
Elevation 1-2 cm (concrete height in accordance with concrete slump), and then by the concrete laser leveling machine to complete a one-time vibration, compaction, leveling work. Emery surface construction, when the pouring of the concrete to achieve the initial coagulation, the emery aggregate and then spread by the use of specialized mechanical operations completed. Formed diamond surface layer and the basement of concrete to form a whole, with high strength, hardness and can not afford dust characteristics. The main construction process is: to remove the floating pulp, the first fabric: primary concrete before the initial setting 5 to 6 into the dry when the provisions of the amount of 2/3 of the emery, disc grinding machine compaction rubbing, so that infiltration of concrete surface layer. Details of the leveling, the second fabric: after a certain period of time and then the remaining 1/3 of the emery according to the kind of spread, with the disc polishing machine and metal trowel as a whole wipe light. Mechanical trowel operation: Depending on the hardening of concrete at least three times the blade-type polishing machine polishing operation. Finishing of the surface details: the final use of mechanical trowel repeatedly wiping completed.[url=http://doublesteelroller.com]Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery[/url]

Product protection
Ground construction completed within 12 hours, with a dedicated concrete geotextile covered, preferably also in the geotextile layer of a layer of quality, the worst 5mm board, to prevent the floor molding and pounding the upper concrete floor when smashing Bad and concrete pulp pollution products. Conservation, according to the usual water conservation can be 7 days. Cutting, cutting should be in accordance with the design requirements, after the surface finish in the ground, that is, to ensure that the final set before the concrete, cutting the spacing, width, depth to meet the design and construction specifications standards. , Until the concrete strength to be used before.
Quality Control and Precautions during Construction
Wall (column) side of the line and leveling: As the wall can not touch the laser leveling machine, along the wall (template) 40 cm range need to manually leveling, so the need for pay-off, as a manual leveling reference. Along the day pouring the scope of supporting the template (the proposed steel), set aside the power transmission rod holes, control the elevation of the template, so that the joints of different positions of the flatness of a large deviation. (Thickness, position according to design requirements may be), leaving the septum, so as not to crack the concrete floor. Laser emitter set up: the laser transmitter should be erected in the best position, can not have objects blocking the beam; tripod set up to be stable, strong, tripod screws and clamps to tighten; the surrounding can not have a larger vibration source; reasonable set of concrete shop Build direction and leveling direction, to determine a reasonable leveling machine construction walking routes, in order to avoid leveling the blind spot. Feeding: Concrete conveying speed should ensure a certain amount, and feed speed uniform, the middle should be reduced to stop.
