Excavation equipment suitable for small shallow foundation pit construction and excavation method thereof

In order to solve the problems that an existing small and shallow foundation pit is low in construction efficiency and poor in construction quality, the excavation equipment suitable for small and shallow foundation pit construction comprises a control system, a driving arm, a rotary excavation structure and a cutting structure, and the rotary excavation structure is arranged at the center position of a mounting base and is in communication connection with the control system; the cutting structures are arranged on the periphery of the mounting base and are in communication connection with the control system. The excavation equipment is reasonable in overall design, simple in structure and convenient to construct, the labor intensity of operators is reduced through the excavation equipment of the structure, the construction efficiency of the small and shallow foundation pit is effectively improved, meanwhile, the construction quality of the small and shallow foundation pit can be ensured when the excavation eq
