In the course of construction, no deformation, no movement and how to control the design thickness, evenness and vertical elevation of the horizontal slope of concrete. In order to achieve the purpose, we Pojiulixin, absorption and application of new advanced techniques, the use of the new technology.
A method of cleaning the bridge surface by a laser leveling machine. The original deck passes through the installation of beam and plate, and the concrete is filled with the seam. After the completion of these processes, there are debris, mortar and concrete blocks remaining on the deck.
The construction lofting is in the form of dense mesh layout, pile location and type lofting, for the purpose of solving the space location and anchoring positioning control of reinforcing steel net, the height control of paving machine's walking track, the control of the thickness of concrete mixture, and the lofting of network layout for the construction lofting.
Laser leveling machine cleaning technical requirements. A. sundries sweep clean; B. residue attached concrete and mortar chisel clean; C. with high pressure water rinse the surface, no residual sand dust.
Therefore, the bridge deck must be cleaned before the pavement, the method is to chisel, shovel, sweep, and water.
