Technical Field
The application relates to the technical field of pipeline laying, in particular to a propelling device.
Background
In current trenchless construction, for long distance, large diameter pipe penetrations, the main problems are that pipe laying thrust or drag is insufficient and pipe laying discontinuity causes pipe springback. The pipe pusher needs larger starting force when starting, stopping and restarting, pipelines are easy to be blocked due to problems of track bending or boulders and the like, and time waste is caused by pipeline rebounding and pipeline laying pause when the pipe pusher returns in a no-load manner; in the horizontal directional crossing project, due to the fact that geological conditions are complex and changeable, tracks are bent, the hole forming quality and the stability of hole walls are poor, the back dragging resistance is large due to the problems of drill sticking, hole collapse, rock debris accumulation and the like, and the problems of insufficient back dragging force, back dragging failure and the like are easily caused.
