Earth pressure balance pipe jacking machine

Abstract

The invention discloses an earth pressure balance pipe jacking machine, which comprises: a cutting cutterhead, a soil bin is arranged on the back of the cutting cutterhead; a cutterhead driving mechanism, the cutterhead driving mechanism includes a central cylinder, a ring, and a power source for driving the force transmission ring to rotate; the force transmission ring is connected to the back of the cutting cutter head, and the central cylinder communicates with the soil bin; the shell, the shell It is cylindrical, and the front end of the casing is connected to the drive box; the screw conveyor extends into the interior of the casing from the rear end of the casing, and communicates with the central cylinder body. The earth pressure balance pipe jacking machine of the present invention has the advantages of compact structure, reliable performance, convenient operation and high degree of automation. Under the condition of harsh construction space, the available space of pipe jacking can be fully utilized, and the overall size of the main engine can be greatly reduced without reducing any functions.

Description

technical field [0001] The invention belongs to the field of building construction and relates to an earth pressure balance pipe jacking machine. Background technique [0002] With the development of urban construction, the population density has increased significantly, and there are more and more means of transportation. Urban traffic congestion restricts urban development. The pipe-curtain underground excavation method has become the research focus of underground space excavation. The pipe curtain construction method is a kind of non-excavation process. During the excavation process, the jacking device of a small-diameter pipe jacking machine is used to insert steel pipes horizontally into the space to be excavated to form a pipe curtain. [0003] At present, the pipe curtain method construction is also widely used in China, but the equipment is often relatively simple, mainly relying on construction experience and human operation to ensure the accuracy and efficiency of ...
