Introduction
Non-excavation guided drilling pipe laying method is a construction technology that uses cliff soil drilling tools, pipeline detection and other technical means to lay, repair, and replace underground pipelines without trenching on the surface. It uses a drilling rig placed on the surface to form a hole by means of water jet or squeeze, and receives a signal from the drill bit at the surface to control the drilling trajectory. There are three stages of dragging back.
