Application construction method of shield separate launching technology in urban drainage engineering

Abstract

The invention relates to the technical field of civil engineering, in particular to an application construction method of a shield separate launching technology in urban drainage engineering. The application construction method of the shield separate launching technology in the urban drainage engineering is suitable for shield construction of drainage pipeline engineering in an urban area, especially for the engineering that a construction site is narrow and small, and all shield equipment cannot be mounted at a time. The application construction method of the shield separate launching technology in the urban drainage engineering comprises the steps of arranging of a launching shaft, arranging of facilities in the launching shaft, hoisting trying of a shield machine, hoisting-into-shaft ofthe shield machine, reinforcing of tunnel opening soil mass, mounting of a tunnel opening rubber cord fabric, chisel-off of a tunnel opening pouring pile, transport arrangement, shield launching preparation, initial tunneling construction, launching of a shield trolley. The application construction method of the shield separate launching technology in the urban drainage engineering adopts the shield machine separate launching technology, the size of the launching vertical shaft can be effectively decreased, the engineering cost is lowered, and meanwhile, the influence on the surrounding environment can also be reduced to the maximum limit.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a construction method for the application of split originating shield technology in urban drainage projects, which is suitable for the construction of shield tunneling projects in urban drainage pipelines, especially where the construction site is narrow and cannot be installed all at once. Engineering of shield tunneling equipment. Background technique [0002] With the climate change in recent years, extreme rainstorms often occur, and urban waterlogging has become more serious, especially in the old urban areas, where the drainage system has long been unable to meet the drainage needs. With the continuous increase of the diameter of new drainage pipes, the traditional technology can no longer meet the construction requirements of existing projects. Due to the advantages of wide application range and large construction pipe diameter, shield tunneling technology is gr...

AI Technical Summary

Problems solved by technology

However, urban drainage projects are often located in urban areas, and there are few places that can be used for large-scale construction land. In consideration of economic factors, the area occupied by the launch shaft is relatively small, so that the shield machine cannot be launched as a whole in a conventional manner, and must be used split origin
