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

The invention discloses a structure construction method at the intersection of the subway on the pipe gallery. The underground diaphragm wall is constructed at the location; earthwork is excavated to the bottom of the comprehensive pipe gallery, the base of the comprehensive pipe gallery is constructed on the top of the underground diaphragm wall, and the concrete structure of the comprehensive pipe gallery is poured; the remaining underground diaphragm walls on both sides of the subway are constructed to form a continuous foundation pit support Protect the structure; excavate the earthwork of the subway foundation pit, construct the concrete structure of the subway and maintain it, backfill the earthwork, and complete the structural construction of the intersection nodes.
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 related to the present invention and do not necessarily constitute prior art. [0003] At present, more and more subways and integrated pipe corridors are being built in cities. Large underground pipeline structures often overlap or cross up and down. The structure is complex and the construction is difficult. According to the general engineering design, the urban subway is buried deep, and the comprehensive pipe gallery is relatively shallow, mostly located above the subway. When the construction of the upper pipe gallery structure has been completed, when the lower structure is constructed, the completed structure shall be protected to prevent its def...
