Underground excavation construction method of assembling corrugated steel plate underground comprehensive pipe corridor

Abstract

The invention relates to an underground excavation construction method of an assembling corrugated steel plate underground comprehensive pipe corridor, and belongs to the technical field of municipalunderground facility construction methods. The underground excavation construction method of the assembling corrugated steel plate underground comprehensive pipe corridor is used for carrying out underground excavation construction on the underground pipe corridor, and has the technical scheme that the method comprises the steps of perpendicularly excavating a vertical shaft, placing a vertical shaft helical bellow in the vertical shaft, connecting one side of the vertical shaft helical bellow to a helical bellow tee, excavating a horizontal pipe corridor along the horizontal direction of thehelical bellow tee, tunneling and assembling corrugated steel plates at the same time so as to form the horizontal pipe corridor, then grouting through a grouting port, and forming an integrated structure through grout and the assembling corrugated steel plate of the horizontal pipe corridor. The underground excavation construction method of the assembling corrugated steel plate underground comprehensive pipe corridor provided by the invention is the pioneer for carrying out underground comprehensive pipe corridor construction by using assembling corrugated steel plate materials, so that the problem that a municipal underground comprehensive pipe corridor needs to be open-excavated is solved; and compared with a traditional concrete-structure comprehensive pipe corridor, the steps of initially lining and temporary supporting are saved, so that the method is simple, convenient and fast, the construction speed is greatly improved, the construction cost is saved, and the method has a great popularization and application value in municipal construction engineering.

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.
