Earth pressure balance push bench

Abstract

The invention discloses an earth pressure balance push bench, which comprises a cutting disk, a disk driving mechanism, a housing and a spiral conveyer, wherein the back surface of the cutting disk is provided with an earth cabin; the disk driving mechanism comprises a central cylinder, a force transfer ring and a power source for driving the force transfer ring to rotate; the force transfer ring is connected to the back surface of the cutting disk; the central cylinder is communicated to the earth cabin; the housing is cylindrical; the front end of the housing is connected to a driving box; and the spiral conveyer extends into the housing from the rear end of the housing and is communicated in the central cylinder. The earth pressure balance push bench dislcosed by the invention is compact in structure, reliable in performance, convenient to operate, and high in automation degree, can make full use of available space of a pipe under the harsh conditions of construction space, and is greatly compressed in whole size of a main engine on the premise of keeping original 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 ...
