| Abstract: | The auto-march-extruding perforator in soil stratum is an equipment for geotechnical construction, which has a shape as a shell. The perforator extrudes and passes through the soil stratum, then a hole is made. The perforation diameter, speed as well as the power supply required are closely related to physical and mechanical properties of soil stratum. In this paper, the design principles, structures and applications of the perforator. The engineering applications showed that this perforator has many advantages, for examples, simple in structure and operation, applicable for various kinds of soil stratum. |
