Expressway surface concrete layer leveling equipment and method for avoiding curl of curing film

Abstract

The invention discloses expressway surface concrete layer leveling equipment and method for avoiding curl of a curing film in the technical field of expressway construction, and the equipment comprises a fixing plate, vertical plates are arranged on the front side and the rear side of the top of the fixing plate, and a fixing groove is formed in the left side of the fixing plate; the opposite sides of the two sets of vertical plates are rotationally connected with rotating rollers through bearings, one end of each rotating roller is connected with the power end of a motor, the motors are fixedly connected to the vertical plates, curing films are wound around the outer walls of the rotating rollers, glue solidifies to enable pressing blocks and the curing films to be bonded together, and it can be effectively guaranteed that the pressing blocks press the curing films. The pressing block is arranged, so that the pressing block cannot be moved by external factors, the maintenance film can be pressed after the maintenance film is laid, the edge curling problem of the maintenance film is solved, a subsequent heavy object placing mode is not needed, and the equipment is extremely suitable for being used on a long-distance expressway.

Description

technical field [0001] The invention relates to the technical field of expressway construction, in particular to an expressway surface concrete layer leveling device and method for avoiding curing film curling. Background technique [0002] After the concrete layer on the surface of the expressway is laid, it is necessary to smooth the surface concrete and cover it with a curing film. After the initial setting of the concrete and before the final setting, the curing film is laid to make the concrete curing film and the concrete surface tightly bonded to promote the hydration effect of the concrete. , plays a significant role in preventing cracking and moisturizing during the concrete curing process. Curling is prone to occur after the curing film is laid, which leads to the inability to protect the concrete. However, the existing concrete layer leveling equipment on the expressway surface is laying the curing film Finally, the curing film cannot be compressed, which leads to...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide expressway surface concrete layer leveling equipment and method that avoid curing film curling, to solve the problem that the existing expressway surface concrete layer leveling equipment proposed in the above-mentioned background technology cannot correct the maintenance after laying the curing film. The film is pressed tightly, which leads to the inability to solve the problem of curling. It also needs to be pressed manually by placing heavy objects. It is more suitable for use on short-distance construction roads, but it is more troublesome when used on long-distance expressways.
