The invention relates to a self-adaptive laying remote triggering shearer and a laying shearing method thereof.The self-adaptive laying remote triggering shearer is used in cooperation with a traction ROV underwater, the self-adaptive laying remote triggering shearer comprises a shearing device and a laying device connecting the shearing device and the traction ROV, the shearing device is connected with an underwater sound controller, the laying device comprises a base assembly, a hydraulic cylinder and a push rod, and a diameter difference exists between the two end faces of the push rod; the limiting pin set is circumferentially arranged on the outer circle surface of the push rod. In the initial state, the limiting pin set abuts against the outer surface of the large-diameter end of the push rod, the shearing device comprises a pressure resisting tank and a cylinder body, a piston rod is arranged in the cylinder body, and the space in the cylinder body is divided into a rod cavity and a rodless cavity. Wherein an electric explosion valve is arranged in the pressure-resistant tank, and a rodless cavity is communicated with an external seawater environment; the initial state in the rod cavity is a full-oil state, a blade is connected to the end of the piston rod, and a tool apron matched with the blade is arranged at the end of the rod cavity. According to the self-adaptive laying remote triggering cutter, remote control triggering can be achieved, and underwater cable damage is achieved.
