Underground oil and gas pipeline excavating device and method

The invention provides a buried oil and gas pipeline excavating device and method, and belongs to the technical field of oil and gas pipeline construction safety. The method mainly comprises the steps that a detection device detects an oil and gas pipeline and an optical cable at a position to be monitored, a control device determines a visual device at a corresponding position according to position information of the oil and gas pipeline and the optical cable, and the corresponding visual device can collect a video picture of the oil and gas pipeline at the position; the control equipment controls the excavating equipment to excavate according to the video picture, and the corresponding water level sensor collects the water level value of the oil and gas pipeline at the position; the control equipment determines whether a pumping signal is generated according to the water level value; the water pumping equipment performs water pumping operation according to the water pumping signal. When the oil and gas pipe
