According to the utility model, ultrasonic waves returned after the ultrasonic waves are transmitted are captured through the ultrasonic probe 1, ultrasonic signals are received and processed through the ultrasonic detection device 4, so that whether foreign matters such as the slag stone 11 exist in a sealing gap or not is displayed in an image mode, when the existence of the foreign matters such as the slag stone 11 exists in the sealing gap is monitored, the slag stone 11 can be judged to invade the inside of a main driving seal, the communication device 5 sends image information to the controller 13 of the shield machine and displays images through the display screen 15 in the main control room 14, meanwhile, the alarm device 6 sends alarm signals, workers can observe and record the diameter, the position, the movement condition and the like of the slag stone 11, then the injection quantity and the main injection area of the grease 10 are regulated according to actual conditions, and whether the invaded slag stone 11 is smoothly discharged out of the main driving seal or not is observed through the grease 10.
The following is one embodiment of the present utility model:

If the ultrasonic detection device 4 detects an abnormal echo signal at a certain moment, it is judged that foreign matters such as slag stones exist in the main drive seal, then the communication device 5 transmits the abnormal signal and the image information to the display screen 15 in the main control room 14, and the alarm device 6 is started at the same time, so that the warning lamp is lighted. As shown in fig. 1, it was confirmed by image information that the slag 11 intruded into the main drive seal, and two abnormal signal sources having a diameter of 10×9mm were provided at the top of the outermost ring monitoring point and the intermediate ring monitoring point, and it was determined that two slag 11 having a diameter of 10×9mm intruded into the main drive seal.

After a period of time, the ultrasonic detection device 4 does not detect that the main driving seal has abnormal echo, and then the seal is judged to be normal, transmission of abnormal signals is canceled, and the warning lamp is turned off. In the tunneling process of the shield machine, the shield machine main driving sealing slag stone intrusion monitoring system is always in a working state, and monitoring of foreign matters such as slag stone 11 and the like is kept.
