It is mainly used for drainage tasks such as urban rainwater, sewage or farmland irrigation and drainage. It is a non-excavation jacking technology used in municipal construction. In the construction of reinforced concrete jacking pipe, it is necessary to first dig a working well, and then lower a section of the pipe through the working well, and then push the lowered pipe into the soil layer. Usually it is not directly pushed in. Generally, the machine head is used to drill a hole first, and then it is pushed while drilling. During the entire construction process, the soil drilled out needs to be transported out during the drilling process.
