Abstract
Description
Technical Field
[0001] This utility model relates to the field of support device technology, and in particular to a support device for stratum pipe jacking construction. Background Technology
[0002] Pipe jacking is a trenchless construction method, a technology for laying pipelines without excavation or with minimal excavation. In pipe jacking, the jacking equipment in the working pit uses the jacking force to overcome the friction between the pipeline and the surrounding soil, pushing the pipeline into the soil at the designed slope, and then removing the excavated soil. After one section of pipe is pushed into the soil, the second section is pushed in to continue jacking. The principle is to use the thrust of the main jacking cylinder and the pipeline and intermediate sections to push the tool pipe or tunneling machine from the working pit through the soil layer all the way to the receiving pit and lift it out.
