An asymmetric excavation device for foundation pits based on non-limiting soil pressure and a method of use

Abstract

The application discloses a kind of based on non-limiting soil pressure's foundation pit asymmetric excavation device and use method, it is related to foundation pit excavation technical field;Including support plate, the support plate and support frame lower end edge are equipped with gyro wheel, and support plate inner wall upper end and center position are embedded with third rotating motor, the third rotating motor one end edge is embedded with sliding bead, and third rotating motor output end is equipped with crushing head, the installation slot is opened in support frame one side edge.This based on non-limiting soil pressure's foundation pit asymmetric excavation device can form stable support by support plate and support frame, and can be stable excavation by support column and gyro wheel, operation is stable, and can be efficiently broken and excavated by crushing head, gyro wheel and excavator, efficiency is better, and when excavator rotates, mud can be guided into extraction pipe, so as to be stably and quickly guided out by first rotating motor and auger, avoid blockage, use more conveniently.
