U-shaped combined type concrete prefabricated box culvert

Abstract

The invention discloses a U-shaped combined type concrete prefabricated box culvert and belongs to the technical field of box culvert engineering. The U-shaped combined type concrete prefabricated box culvert aims at solving the problems that during box culvert field pouring, construction is complex, the construction period is long, an overall prefabricated box culvert is difficult to transport, and lifting is difficult. An upper box culvert and a lower box culvert are U-shaped concrete prefabricated box culverts. The height of the U-shaped side wall of the upper box culvert is smaller than that of the U-shaped side wall of the lower box culvert. Transverse installation grooves are formed in the top face of the upper box culvert and the bottom face of the lower box culvert. Multiple longitudinal installation grooves are formed in the top face of the upper box culvert and the bottom face of the lower box culvert, and the longitudinal installation groove in the upper box culvert are in one-to-one correspondence with the longitudinal installation grooves in the lower box culvert. A through hole is formed between every two corresponding longitudinal installation grooves. The through holes are located in the side walls of the upper box culvert and the lower box culvert. Longitudinal PC steel bars are arranged in the through holes. The upper box culvert and the lower box culvert are connected through the longitudinal PC steel bars. The U-shaped combined type concrete prefabricated box culvert can be prefabricated and assembled, transportation is convenient, damage brought by soil sedimentation can be resisted, and the sealing performance is high.

Description

technical field [0001] The invention relates to a concrete box culvert, in particular to a U-shaped combined concrete prefabricated box culvert, which belongs to the technical field of box culvert engineering. Background technique [0002] The comprehensive pipe corridor is the comprehensive corridor of underground urban pipelines, which is composed of concrete box culverts. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. The main box culvert of the comprehensive pipe gallery is mainly divided into two types: cast-in-place concrete box culvert and factory prefabricated type. The cast-in-place concrete box culvert has...
