Description
technical field [0001] The invention belongs to the technical field of excavating hole equipment, and in particular relates to an excavating equipment used for variable-diameter holes. Background technique [0002] At present, in some construction fields, excavation holes with variable diameter structures are required in some places, such as cast-in-place concrete piles. By adopting excavation holes with variable diameter structures, it is beneficial to improve the anti-seismic effect, but existing excavating equipment is difficult to meet the requirements of variable diameter excavation holes. Due to the requirements of hole excavation, multiple constructions must be adopted, which has poor flexibility and is difficult to meet the construction requirements. [0003] Therefore, many customers asked us to invent an excavation equipment for variable diameter holes. Contents of the invention [0004] In order to achieve the above technical purpose, the present invention prov...
