Problems solved by technology
[0002] In the excavation construction of the pole foundation of the rural power network project, when encountering high water level geology, the hook excavation method is usually adopted; in order to prevent landslides, it is often adopted to expand the working surface, excavate a large pit, and increase the vertical Pole and backfill construction is difficult, time-consuming, high construction cost, difficult construction, poor pole stability
Manual excavation requires prefabricated cement rings, and excavation while pumping water with water pumps, which is slow, inefficient, long in cycle, high in cost, and poor in safety performance
