Detachable multi-angle steel jacking pipe deviation rectifying device

Abstract

The invention relates to the downward deviation problem during the jacking process of a steel jacking pipe and particularly relates to a detachable multi-angle steel jacking pipe deviation rectifyingdevice which comprises a concrete base and an arc-shaped steel plate tripod, wherein each of the concrete base at the lower part and the arc-shaped steel plate tripod at the upper part has the detachable function, is convenient to mount and is recycled; a support steel plate is clamped and connected between clamping grooves in corresponding positions between the lower bottom surface of an arc-shaped steel plate and the upper bottom surface of a bottom steel plate through the arc-shaped steel plate tripod; the support steel plate is clamped at different positions to adjust the angle between thearc-shaped steel plate and the bottom steel plate, so that the problem that the steel jacking pipe falls off to different degrees on engineering is further solved, and different-angle deviation rectification of the steel jacking pipe is realized with high flexibility and convenience; steel balls similar to abaci in shape are configured on the upper surface of a cambered surface steel plate, so that the front end of the steel jacking pipe can conveniently move on the cambered surface steel plate. The detachable multi-angle steel jacking pipe deviation rectifying device can better solve the problem about downward deviation during the jacking process of the steel jacking pipe.

Description

technical field [0001] The invention belongs to the technical field of tunnel and underground engineering construction, and relates to the problem of downward deflection of steel pipe jacking during the jacking process, in particular to a detachable multi-angle steel pipe jacking deviation correction device. Background technique [0002] Pipe jacking construction is a kind of underground pipeline construction technology. It adopts the pipe jacking method and can cross roads, railways, buildings and various underground pipelines without excavating the surface layer. With the continuous development of urbanization in our country, the use of trenchless construction technology is more and more popular. In addition, the pipe jacking technology has the characteristics of no need to block traffic, less demolition workload, and less impact on the surrounding environment, and has been widely used in urban construction. After years of development, my country's pipe jacking technology...

AI Technical Summary

Problems solved by technology

If the operation is improper, it may cause the jacking force to rise rapidly and the pipe joint to be damaged. In severe cases, the pipe cannot be jacked, which will cause serious quality and safety accidents and cause major economic losses.

Therefore, special attention must be paid to the correction of the deviation during the jacking process, especially the problem of the steel pipe jacking during the jacking process, which has always been a major problem in the construction of the pipe jacking. The present invention proposes a detachable multi-angle steel pipe jacking The deviation correction device will effectively solve the downward deviation problem of the steel jacking pipe
