Shock excitation device multi-degree-of-freedom support carried on TBM, shock excitation device and method

The invention belongs to the technical field of seismic wave method geological detection, and provides a shock excitation device multi-degree-of-freedom support carried on a TBM, a shock excitation device and a method. The shock excitation device multi-degree-of-freedom support carried on the TBM comprises sliding rails, a base, a control module, a mechanical arm, a rotating flange and a rotatingmodule. The sliding rails are installed on the two sides of the TBM main beam, and the base can move front and back in the axis direction of the tunnel along the sliding rails. The mechanical arm is installed on the base, and the length and the angle of the mechanical arm are adjustable. The rotating flange is installed on the mechanical arm and used for fixing the shock excitation device. The control module is connected with the base and the mechanical arm through corresponding driving mechanisms and used for controlling the movement of the base and the action of the mechanical arm. The control module is further conn
