[0026] It should be noted that some existing subway pit retaining support structures lack the function of monitoring the deformation of the pit sidewalls during actual use. When the pit sidewalls are severely deformed, the multiple supporting steels on the subway pit retaining support structure will be unevenly stressed. In severe cases, collapse may occur, reducing the safety of the subway pit support.

[0027] In this embodiment, when the subway foundation pit is enclosed and supported, the cement board 1 is poured on the side wall of the subway foundation pit, the protective plate 2 is installed in the subway foundation pit, the protective plate 2 and the cement board 1 are in conflict, and multiple support columns 3 are installed in the subway foundation pit.

In the process of supporting the subway foundation pit, the monitoring mechanism 6 is set on the support plate 4, located on one side of the protective plate 2. When the side wall of the subway foundation pit is deformed to a certain range, the protective plate 2 is also deformed by external force. When the protective plate 2 is squeezed to a certain range, it will contact the monitoring mechanism 6, thereby triggering the monitoring mechanism 6 to alarm, so that the staff can timely understand the deformation of the subway foundation pit, and thus make overall rectifications and improvements to the safety of the subway foundation pit enclosure support.

The protective plate 2 is squeezed to the monitoring rod 602. The monitoring rod 602 is squeezed by the force and drives the block 603 to compress the spring 604. As the monitoring rod 602 moves, it will contact the trigger button 605, thereby triggering the buzzer 606 to alarm. In this way, the staff can understand the deformation of the subway foundation pit in time, and thus make overall rectifications to improve the safety of the subway foundation pit retaining support.
