A construction method for the joint of porous rectangular pipe jacking and open and dark excavation transfer pipe gallery

Abstract

The invention discloses a construction method for the joint between a porous rectangular pipe jacking and an open and concealed excavation handover pipe gallery, which comprises sequentially connected pipe jacking and pipe gallery sections, a working well section, a connecting transition section, and an open and dark digging pipe gallery section; the pipe jacking and pipe gallery section consists of Pipe joints connected in sequence are formed and at least two sections are arranged in parallel. One end of the wall of the pipe gallery in the working well is connected with a converging triangular column located in the transitional section. The converging triangular column is in the shape of a vertical column. The end away from the clamping wall, the two sides of the connecting triangular column away from the clamping wall coincide with the two sides of the wall of the exposed and concealed excavation pipe gallery respectively; Membrane, the waterproof membrane extends from the outside of the transition section wall to the end of the lining wall near the pipe joint. The smooth connection between the open cut pipe gallery and the porous pipe jacking gallery is realized, and the structure is safe and reliable; the waterproof method at the weak position of the working well and the pipe jacking joint is simple and easy to prevent water from entering the joint pipe gallery.

Description

technical field [0001] The invention belongs to the field of underground building construction, and in particular relates to a construction method for a joint between a porous rectangular pipe jacking and an open and dark excavation transfer pipe gallery. Background technique [0002] The underground comprehensive pipe gallery is an important infrastructure and lifeline to ensure the operation of the city. In recent years, my country is vigorously promoting the construction of the urban comprehensive pipe gallery. In the initial stage of the construction of the new urban area, the obstacles of using the open-cut method or the underground method are relatively small, which has obvious technical and economic advantages. However, with the promotion of the construction of the underground comprehensive pipe gallery, the interaction between the underground comprehensive pipe gallery and other important structural facilities is also increasing. Construction methods are also gradually...
