Problems solved by technology

[0003] However, at present, most of the site characteristics in our country belong to the compound stratum structure, so the underground construction often encounters that the equipment used to break the excavated pipes is used in the compound stratum, especially the stratum with cementation characteristics, and its breaking ability is often insufficient. question
[0004] Because most of the existing equipment for breaking and excavating pipelines use the cutting cutter head composed of a plurality of cutting tools to destroy the corresponding geological structure, and the propulsion mechanism with the cutting cutter head as the main tool for destroying the geological structure is usually in a simple geological structure. And under normal conditions, it is indeed possible to efficiently drill and push out the pipeline; however, when it advances in a composite geological structure with uneven

Abstract

The non-contact cementing stratum breaking and pipe pushing mechanism includes one main pushing pipe, one non-contact cementing stratum breaking set mounted in the front end of the main pushing pipe, one hydraulic pushing set applying force to the main pushing pipe to go forward or alter direction, one pumping set to convey the broken cementing material to the well for removing, and one main pushing pipe sealing set to seal the back end of the main pushing pipe. The non-contact breaking set includes one hydraulic slide way inside the main pushing pipe, and at least one hydraulic knife to jet high speed fluid breaking the cementing stratum. The present invention can push forwards in cementing stratum to form ring pipeline without jamming, and is suitable for different geologic frameworks.

Description

technical field [0001] The invention relates to a machine tool used for breaking and excavating pipelines, in particular to a non-contact breaking propulsion mechanism for breaking cemented material sites. Background technique [0002] Constrained by the existing landscape, buildings and facilities in the metropolitan area, as well as avoiding too much impact on the busy traffic in the metropolitan area, as well as avoiding damage to the ecology and surface water and soil conservation, the use of the advancing construction method can effectively suppress this problem, so Underground construction has become an inevitable engineering construction technology for construction operations in urban areas; and when underground construction is in progress, the propulsion mechanism for breaking and digging formed pipelines from the working shaft wall is an indispensable and necessary machine tool. [0003] However, at present, most of the site characteristics in our country belong to ...
