In the embodiment of the present application, the second portion end of the steel pipe 2 is screwed with the ball valve 3.
In the embodiment of the application, the transparent tube 4 is a U-shaped tube, a first end of the U-shaped tube is connected with the ball valve 3, and a second end of the U-shaped tube is arranged upwards; or the first end of the U-shaped pipe is connected with the ball valve 3, and the second end of the U-shaped pipe faces the enclosure structure 1.

In the embodiment of the present application, the transparent tube 4 is a glass tube or a plastic tube. The water level inside the tube can be seen through the glass tube or the plastic tube.
The underground water level monitoring method for the starting stage and the receiving stage of the shield tunneling machine has the following advantages:
(1) the mode of reserving the holes on the enclosure structure is changed into the mode of burying steel pipes on the enclosure structure, so that the risk of the enclosure structure caused by reserving the holes is avoided;
