Description

Technical Field

[0001] The utility model relates to the technical field of road engineering construction, in particular to a combined formwork for road assembled base edge sealing concrete construction. Background Art

[0002] With the advancement of urbanization, urban transportation construction has always been one of the key projects of national development. Improving the efficiency, quality and safety of road construction is the key to urban road construction. In recent years, prefabricated bases of urban roads have been widely used. Edge-sealing concrete needs to be constructed between the prefabricated base of the road and the curb. At present, there are several construction methods for conventional edge-sealing concrete: First, after the installation of the prefabricated base block is completed, the construction width of the edge-sealing concrete is laid out, including the curb foundation, and then the formwork is set up and the concrete is poured. The curb masonry groove is manually cleaned before the concrete is finally set. This construction method requires additional manual cleaning of the curb masonry groove, which causes concrete waste in the process and increases construction costs. Second, the edge-sealing concrete on the inner side of the curb is constructed first, and then the curb foundation is poured. This construction method The first method requires two times of supporting and dismantling the formwork, which increases labor costs. The pouring of the curbstone foundation concrete requires the removal of the edge-sealed concrete formwork on the inner part of the curbstone. The construction period is long, which affects the construction progress. The edge-sealed concrete on the inner part of the curbstone is poured separately from the curbstone foundation concrete; the third method is to first cast the curbstone foundation as a whole, then construct the curbstone, and finally supplement the edge-sealed concrete on the inner part of the curbstone. This method pours the concrete in two times, with a long construction period, which affects the construction progress. The second concrete construction process is prone to curbstone pollution, affecting the appearance quality of the curbstone.
