Mud technology in trenchless construction

If the blade foot is slightly larger than its size corresponding to the outer diameter of the pipe, it is possible to reduce the frictional resistance of the outer wall of the pipe. This prevents the upper layer from directly pressing on the tube body. As long as the soil is hard enough, this method will achieve the desired effect. And if the supporting medium is pressed into the gap formed between the pipe and the soil layer, the effectiveness of this method can be greatly improved, and it can be maintained for a certain period of time, which is enough to push into a relatively long pipeline. While supporting the excavation jacking pipe, the supporting medium can also serve as a lubricant to reduce friction.
