Problems solved by technology

Generally, in order to reduce the excavation depth of underground engineering and save cost, the vertical distance between the two structures at the intersection is relatively close, and it is difficult to completely isolate the two structures without affecting each other, which greatly increases the foundation pit support at the intersection. and the construction difficulty of the main structure, if the control is not good, the deformation and damage of the existing structure will be caused, resulting in engineering accidents

Abstract

The invention discloses a structure construction method for crossing a subway crossing-joint on a pipe gallery. The structure construction method comprises the following steps that after construction positioning is carried out, steel sheet piles are constructed on two sides of a comprehensive pipe gallery as foundation pit supporting structures, and underground diaphragm walls are constructed at set positions on two sides of a subway; earthwork is excavated to the bottom of the comprehensive pipe gallery, a comprehensive pipe gallery base is constructed at the tops of the underground continuous walls, and a comprehensive pipe gallery concrete structure is poured; the remaining underground diaphragm walls on the two sides of the subway are constructed, and a continuous foundation pit supporting structure is formed; and earthwork of the subway foundation pit is excavated, a concrete structure of the subway is constructed and maintained, the earthwork is backfilled, and structural construction of the cross-joint is completed.

Description

technical field [0001] The invention belongs to the technical field of construction of a pipe gallery crossing a subway crossing node, and in particular relates to a structural construction method for a pipe gallery crossing a subway crossing node. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, there are more and more subways and comprehensive pipeline corridors being built in the city. The large underground pipeline structures often overlap or pass through. The structure is relatively complicated and the construction is difficult. According to the general engineering design, the buried depth of the urban subway is relatively deep, and the buried depth of the comprehensive pipe corridor is relatively shallow, mostly located above the subway. When the upper pipe gallery structure has been constructed, it is necessary to protect the com...
