Abstract
The invention relates to a rectangular large section steel structure assembled temporary support pipe joint jack-in mechanism. Pipe-jacking construction is an underground pipeline construction method, a surface layer does not need excavating, but under the restriction of geological conditions and the section size, the pipe-jacking construction is not generally applied. The rectangular large section steel structure assembled temporary support pipe joint jack-in mechanism comprises a working well and a receiving well, a pipe-jacking section is arranged between the working well and the receiving well, and the pipe-jacking section is formed by a plurality of steel pipe joints. Each steel pipe joint is assembled by steel plates in a splicing mode, and the overall section of each steel pipe joint is in a rectangular shape. The surfaces of outer pipes of the steel pipe joints are face plates, and longitudinal rib plates perpendicular to the face plates and parallel to the direction of channels are arranged on the inner surfaces of the face plates. Transverse rib plates which are perpendicular to the longitudinal rib plates and parallel to the cross sections of the channels are arranged between the longitudinal rib plates. An end plate is arranged at the position of one pipe end face of each steel pipe joint. H-section steel is arranged in inner pipes of the steel pipe joints in a transverse and vertical intersection mode. The jack-in mechanism can effectively reduce self-weight and jacking force of a pipe-jacking structure, overcomes the defect that a pipe-jacking heading machine can not be used, and achieves the application of large section steel pipe joint jack-in method process in shallow buried subway auxiliary projects.
Description
Technical field
the invention belongs to subway construction field of engineering technology, be specifically related to a kind of rectangle big cross section steel structure assembling temporary support tube coupling jacking mechanism.
Background technique
Jacking construction is a kind of underground pipeline construction method, and it does not need to excavate surface layer, and can highway crossing, railway, above ground structure and underground utility etc.It starts from the Northern Pacific Railroad laying project construction of the U.S. in 1986 the earliest.It is reported that China's jacking construction starts from Beijing of nineteen fifty-three, Shanghai also started push pipe test in 1956 afterwards.At present, the method for construction that pipe jacking construction technique has become a kind of routine is used, and many pipelines such as running water pipe, gas pipe, power cable, telecommunication cable and the power station circulatory system also use pipe jacking construction technique.In recent years, pipe jacking construction technique is also applied in subway engineering gradually, but be subject to the restriction of geological condition and cross-section size, the application of pipe jacking tunnelling machine in city track traffic engineering is actually rare, only has the stratum based on weak soil such as Shanghai, Hangzhou, just likely use pipe jacking tunnelling machine, and structural type mostly is assembled prefabricated pipe section.
Summary of the invention
The object of this invention is to provide a kind of rectangle big cross section steel structure assembling temporary support tube coupling jacking mechanism significantly reducing dead load and top power.
The present invention has the following advantages:
The present invention performs active well and received well in passage both sides, arranges parados and force transmission rack after push pipe in active well, and push pipe form adopts rectangle big cross section steel structure assembling temporary support tube coupling, arranges temporary supporting system in tube coupling.Steel structure assembling temporary support tube coupling is utilized to replace traditional push pipe prefabricated pipe section, jack force transmission rack replaces pipe jacking tunnelling machine, this mode can effectively reduce jacking pipe structure deadweight and top power, avoid the drawback that can not utilize pipe jacking tunnelling machine, achieve the application of rectangle big cross section steel pipe joint jacking technique in shallow embedding subway appurtenant work, rationally reduce engineering cost.The present invention has higher economic benefit and social benefit, has a wide range of applications in the similar engineerings such as subway, railway, highway, water conservancy.
