Problems solved by technology

[0003] At present, there are mainly two types of pipe jacking machines used for pipe curtain construction: mud-water balance type and earth pressure balance type. The scope of application of these two types of equipment has certain limitations. The construction site occupies a large space and the efficiency is low. The traditional spiral pipe jacking technology cannot Realize high-precision guidance and deviation correction, but cannot realize fast step change and jacking

Abstract

The invention discloses a spiral pipe jacking machine. The spiral pipe jacking machine comprises a driving device, a spiral casing pipe device, an excavating device and a guiding device, wherein the driving device is connected with the spiral casing pipe device and the guiding device, the guiding device is located at the front end of the spiral casing pipe device, the spiral casing pipe device isconnected with the excavating device, and the excavating device is located at the front end of the spiral casing pipe device and the rear end of the guiding device. According to the spiral pipe jacking machine, high-precision guiding and deviation correction are achieved through the guiding device; and in addition, the spiral pipe jacking machine has the advantages of being small in occupied spaceand high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a screw pipe jacking machine. Background technique [0002] Pipe jacking machines are widely used in the fields of pipe screen construction, pipeline construction and tunnel landslide rescue, and have broad application prospects. [0003] At present, there are mainly two types of pipe jacking machines used in pipe curtain construction: mud-water balance type and earth pressure balance type. The scope of application of these two types of equipment has certain limitations. The construction site occupies a large space and has low efficiency. The traditional spiral pipe jacking technology cannot Realize high-precision guidance and deviation correction, but cannot realize fast step change and jacking. [0004] Therefore, how to provide a screw pipe jacking machine that occupies less space, has high construction efficiency, and can realize high-precision guidance and devia...
