Prefabricated part, assembled socket type square pipe culvert and construction method of assembled socket type square pipe culvert

Abstract

The invention provides a prefabricated part, an assembled socket type square pipe culvert and a construction method of the assembled socket type square pipe culvert. The prefabricated part is provided with a hole, and the hole enables the prefabricated part to form an enclosed pipe wall; a plurality of first reinforcing steel bars and a plurality of second reinforcing steel bars are arranged in the pipe wall, the plurality of first reinforcing steel bars are sequentially enclosed in the pipe wall with the same cross section along the shape of the pipe wall, and the plurality of first reinforcing steel bars are arranged at intervals along the length direction of the prefabricated part; the multiple second steel bars connect the multiple first steel bars arranged at intervals in the length direction of the prefabricated part, and the multiple second steel bars are arranged at intervals in the cross section shape of the pipe wall. One end of the prefabricated part is provided with a concave bell mouth, the other end of the prefabricated part is provided with a protruding insertion opening, and the bell mouth is matched with the insertion opening in appearance. Compared with the prior art, the construction problems that the municipal drainage pipe culvert needs cast-in-place after on-site formwork erecting, and formworks are difficult to dismantle are effectively solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated component, an assembled socket-type square pipe culvert and a construction method thereof. Background technique [0002] The construction of pipes and culverts in existing municipal projects mostly adopts the traditional cast-in-place concrete process, which is backward in technology, and the site excavation area is large, requiring support formwork. When the size of some pipes and culverts is small, it is difficult to dismantle and recycle the formwork. When pouring concrete on site, a large construction operation surface is required, which seriously pollutes the site environment and destroys vegetation. [0003] Most of the current similar prefabricated components are designed according to the "Precast Concrete Integrated Pipe Gallery Manufacture and Construction" 18GL205. This atlas is suitable for large-scale prefabricated pipe galleries, and rel...
