For the spiral winding method, at present, china has a winding device and a grouting device which are independently researched and developed on a non-circular pipeline. For example, the publication number CN204942904U discloses a following type winding machine for trenchless rehabilitation of special-shaped pipelines, the design of a transmission chain mechanism on the following type winding machine is more regular, so that a traction mechanism on the following type winding machine can only realize linear following type driving, and the structure of the existing winding device is not enough to adapt to curves and turns of pipelines.

In mechanical walking spiral winding, the actual site conditions encountered are very complex and irregular. For example, when the special-shaped culvert is wound by a special-shaped culvert, such as a round or rectangular culvert, a horseshoe culvert, a triangular culvert and the like, the culvert is not in a straight line structure or a structure with the same size, and the culvert can change or turn according to obstacles or actual landforms and mines during the extending process. Therefore, the existing common winding chain link cannot adapt to the complex working conditions, and the self-work is difficult to complete in the culvert with the turning diameter change.
