Description

TECHNICAL AREA

The present utility model relates to the technical field of construction of a jacking pipe, in particular a support device for construction of a jacking pipe in underground railway construction.

STATE OF THE ART

The construction of a jacking pipe is a construction method without excavation and it is a construction technique for pipe burying that does not require any excavation or requires little excavation. The construction method of a jacking pipe consists in using the jacking force generated by the jacking system in the work pit, overcoming the frictional force between the pipeline and the surrounding earth, pushing the pipeline into the earth according to the intended gradient and transporting the earth away, whereby after a pipe section in the earth layer has been driven, the second pipe section is driven further. The principle is to use the thrust of the main jacking cylinder, the pipeline station and the intermediate jacking station to drive the tool pipe or the jacking machine out of the working pit through the layer of earth into the receiving pit for hanging, with the pipeline following the tool pipe or the jacking machine, and between the working pit and the receiving pit is buried. It is necessary to support and fix the jacking pipe when it is pushed in. But the existing support device for construction of a jacking pipe has certain disadvantages and certain limitations in use, and cannot apply to different sizes of jacking pipes. In addition, the frictional force between the jacking pipe and the supporting device is too great, which lowers the work efficiency.
