Reinforcing steel bar structure for intersection of three compartments of pipe galleries

Abstract

The invention relates to the technical field of pipe galleries, in particular to a reinforcing steel bar structure for an intersection of three compartments of pipe galleries. The reinforcing steel bar structure for the intersection of the three compartments of the pipe galleries is located at the intersecting position of the pipe galleries located in two directions, and comprises a partition, a top plate, a middle plate and a bottom plate, wherein the top plate and the middle plate form an upper-layer cavity; the middle plate and the bottom plate form a lower-layer cavity; the top plate, themiddle plate and the bottom plate are made of prefabricated slabs; the structures of the various prefabricated slabs are the same as the structures of cross sections of a first compartment, a second compartment and a third compartment; the partition is used for connecting and supporting the various prefabricated slabs; a pipeline reserved port and a stair reserved port are formed in the prefabricated slab of the middle plate; and hidden beam reinforcing steel bars are distributed on the peripheries of the pipeline reserved port and the stair reserved port. According to the reinforcing steel bar structure for the intersection of the three compartments of the pipe galleries provided by the invention, the stability of the intersecting position of the pipe galleries can be effectively improved, and the intersecting position of the pipe galleries can be conveniently constructed.

Description

technical field [0001] The invention relates to the technical field of pipe corridors, in particular to a steel bar structure for a three-chamber intersection of a pipe corridor. Background technique [0002] Because the traditional direct buried pipeline occupies a lot of underground space on the road, and the laying of the pipeline is often not synchronized with the road construction, resulting in frequent excavation of the road, which not only seriously affects the normal traffic of the road, but also brings serious environmental pollution problems such as noise and dust. , Great inconvenience to people's transportation and living conditions. In order to solve the above problems, there has been a pipe gallery structure for laying underground pipelines. The pipe corridor is a comprehensive corridor of underground urban pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the construction of pipe corridors is generally divided into on-site pouring and prefabricated pipe gallery structures. For the method of on-site pouring, it is necessary to carry out processes such as steel bar processing and binding, formwork support, concrete pouring, maintenance, and formwork removal on the construction site. The process is complex and the construction period is long; for the prefabricated prefabricated pipe gallery structure, the integral prefabricated pipe gallery is often bulky and heavy, and the transportation from the factory to the construction site and on-site hoisting are extremely inconvenient, and the stability of the integral prefabricated pipe gallery is poor. Pipe gallery poured in situ

According to the system layout of the pipe gallery, cross pipe gallery is often encountered. At the intersection of the pipe gallery, the area of ​​the intersection of the pipe gallery increases, and the volume and weight of the prefabricated pipe gallery increase accordingly, thus increasing the difficulty of installation, and Due to the increase in volume and weight at the intersection of pipe corridors, the stability of the integral prefabricated pipe gallery is not high
