Reinforced concrete pipe jacking pipe joint and machining die thereof

Abstract

The invention discloses a reinforced concrete pipe jacking pipe joint and a machining die thereof, and belongs to the technical field of reinforced concrete pipe jacking pipe joints. An outer connecting pipe and an inner bearing pipe which are matched with each other are arranged at the upper end and the lower end of an inner thin steel bar pipe, and transverse reinforcing bodies which are annularly distributed are arranged at the joints of the outer connecting pipe, the inner bearing pipe and the inner thin steel bar pipe, so that the connecting strength of the contact positions of every two adjacent transverse reinforcing bodies is improved; after concrete filler is poured, the outer side of the inner thin steel bar pipe is filled with the concrete filler, and the concrete filler is bonded with the transverse reinforcing bodies, so that the overall mechanical strength of the inner thin steel bar pipe, the outer connecting pipe, the inner bearing pipe and a concrete forming layer is further improved; meanwhile, a plurality of elastic buckling bag heads are annularly distributed on the inner connecting part, and the elastic buckling bag heads are matched with buckling grooves in a one-to-one mode, so that the bearing connection of the inner bearing pipe and the outer connecting pipe is realized when the two pipe joints are connected; and through multi-point buckling connection, the strength is enhanced, and the situation that the connecting position of the pipe jacking pipe joint is subjected to friction due to jacking construction operation, so that dislocation movement occurs, and the sealing performance is reduced is not prone to being caused.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete pipe-jacking pipe joints, and more specifically relates to a reinforced concrete pipe-jacking pipe joint and a processing mold thereof. Background technique [0002] Reinforced concrete pipe jacking is a kind of sewage pipe that is made of cement, steel bars, sand, stones, etc. as raw materials and mixed with a centrifuge. It is mainly used for drainage tasks such as urban rainwater, sewage, or farmland irrigation and drainage. It is a municipal construction project. non-excavation submerged pipe jacking technology. [0003] In recent years, with the rapid promotion and application of non-excavation technology, especially pipe jacking technology, pipe jacking technology has been widely used in the field of municipal engineering, in which electric pipe jacking is used for the underground laying of cables, and large-diameter reinforced concrete pipes are used as the Mainly, the interfac...

Problems solved by technology

Pipe jacking construction has high requirements on the waterproof performance of pipe joints, but in many engineering projects, water leakage occurs in pipe joints

[0004] However, in the process of pipe jacking construction, there is inevitably frictional resistance between the outer surface of the pipe jacking and the soil, which will generate force on the surface of the pipe jacking, and for ordinary connected pipe jacking, it will cause shaking between the pipe jacking , which is not conducive to pipe jacking construction, and it is very easy to cause misalignment and movement at the joint joints of pipe jacking, resulting in damage to the lining at the joint of pipe jacking due to excessive force, and loss of sealing at the joint, resulting in pipeline leakage and affecting pipe jacking service life, and at the same time, after the dislocation of the connection of the pipe joint occurs, it will hinder the jacking construction of the pipe joint
