Porous rectangular pipe jacking and open and underground excavation connection pipe gallery joint and construction method thereof

Abstract

The invention discloses a porous rectangular pipe jacking and open and underground excavation connection pipe gallery joint. The joint comprises pipe jacking gallery sections, a working well section,a connecting transition section and an open and underground excavation pipe gallery section which communicate in sequence, wherein the pipe jacking gallery sections are formed by sequentially-connected pipe joints, at least two pipe jacking gallery sections are arranged in parallel, one end of a pipe gallery wall in a working well is connected with a connecting triangular column located in the connecting transition section, the connecting triangular column is in a vertical column shape, the end, close to a clamping wall body, of the connecting triangular column is wider than the other end faraway from the clamping wall body, the two sides of the end, away from the clamping wall body, of the connecting triangular column coincide with the two sides of a wall of an open and underground excavation pipe gallery correspondingly, a transition section wall, an inner lining wall, a top plate and a bottom plate of the working well are coated with waterproof coiled materials, and the waterproofcoiled materials extend from the outer side of the transition section wall to the end, close to a pipe joint, of the inner lining wall. Smooth connection between an open excavation pipe gallery and aporous pipe jacking pipe gallery is achieved, the structure is safe and reliable, the waterproof method at a weak position of closing of the working well and a pipe joint of pipe jacking is simple andeasy to implement, and water is prevented from entering a joint pipe gallery.

Description

technical field [0001] The invention belongs to the field of underground building construction, and in particular relates to a joint between a porous rectangular pipe jacking and an open and dark excavation transfer pipe gallery and a construction method thereof. 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 g...
