Technical Field
The utility model relates to the technical field of pipeline construction, in particular to a supporting device for a micro-caliber pipeline trenchless pipe splicing corrugated steel lining plate.
Background
Along with the development of cities, the utilization rate of urban land areas is concerned more and more, and various underground buildings, pipelines and other projects reflect the utilization of underground spaces by people. This patent mainly introduces a construction technology of pipe is pieced together to no excavation of micro-bore pipeline.
In the non-excavation industry, the utilization of underground space is mainly reflected in the development of underground pipelines for water supply and drainage, and the water supply and drainage pipelines mainly adopt three modes of open trench digging, pipe jacking and pipe pulling to lay various pipelines. The open trench digging method occupies a large area of the working surface, and is not suitable for cities and areas with heavy traffic. The construction mode of the top pipe and the pull pipe can greatly reduce the occupied area of the working surface, but is limited by factors such as soil layer, soil covering thickness and the like, and is not suitable for all construction environments.
