[0002] Before the construction of asphalt pavement, the curbstones must be installed first. After the curbstones are installed, concrete backrests or soil filling and compaction must be constructed. Before the relevant pre-embedded work in the median strip is completed, the soil cannot be backfilled, so a concrete backrest is needed to support it to prevent the curbstones from being squeezed out during the paving and compaction of the asphalt pavement. It is difficult to repair after squeezing out. First, it affects the overall linear shape of the curbstones. Second, repairing the trimming causes waste of resources and increased costs. Third, it causes the road width to exceed the allowable deviation of the specification. Therefore, it is necessary to construct a concrete backrest after the curbstones are installed. At present, when constructing the concrete backrest, most of them are to set a casting template on the outside of the curbstone, and then use a concrete truck to pour concrete between the outside of the curbstone and the template, and then smooth and dry it. However, this is more troublesome and requires disassembly and assembly of the casting template. It is labor-intensive and has low construction efficiency. Utility Model Content
