A method of underground excavation construction of assembled corrugated steel plate underground comprehensive pipe gallery

Abstract

The invention discloses a method for underground excavation construction of an underground comprehensive pipe gallery assembled with corrugated steel plates, which belongs to the technical field of construction methods for municipal underground facilities and is used for underground excavation construction of an underground pipe gallery. The technical plan is: excavate the vertical shaft vertically, place the spiral corrugated pipe in the shaft, connect the spiral corrugated pipe tee on one side of the vertical shaft spiral corrugated pipe, excavate the horizontal pipe gallery horizontally along the spiral corrugated pipe tee, and excavate one side at the same time The corrugated steel plates are assembled to form a horizontal pipe gallery, and then grouting is performed through the grouting port, and the grouting and the assembled steel corrugated plates of the horizontal pipe gallery form an integrated structure. The invention is the first to use the assembled corrugated steel plate material for the construction of the underground comprehensive pipe gallery, which solves the problem that the municipal underground comprehensive pipe gallery requires open-cut construction. Compared with the traditional concrete-structured comprehensive pipe gallery, the initial lining and The steps of temporary support are simple and fast, which greatly improves the construction speed and saves the construction cost, and has excellent promotion and application value in municipal construction projects.

Description

technical field [0001] The invention relates to a construction method for an urban underground comprehensive utility gallery, and belongs to the technical field of construction methods for municipal underground facilities. Background technique [0002] In the layout of municipal pipelines, the construction of comprehensive pipeline corridors can develop and utilize underground space resources more scientifically and rationally. The construction of comprehensive utility corridors can centrally arrange the six major types of municipal pipelines to form a new type of urban underground facilities management system, which is the current development trend of urban municipal construction. In the construction of underground utility tunnels, corrugated steel structures are more and more widely used due to their advantages of environmental protection, low cost, short construction period, earthquake resistance and disaster prevention, and reliable operation. [0003] At present, the c...

AI Technical Summary

Problems solved by technology

[0003] At present, the construction of many municipal comprehensive utility corridors requires all the pavement to be dug out, then the pipelines are arranged, and finally the pavement is repaired, which is labor-intensive, time-consuming, and expensive.

At the same time, in many areas, because the underground pipelines are generally buried deep, all excavation greatly increases the construction time, greatly affects the traffic in the city, and brings great inconvenience to the lives of citizens.
