In foundation pit engineering, horizontally arranged purlins are generally set on the sides of the retaining members; round steel tube purlins are widely used due to their low cost and high reuse rate. The round steel tube purlins can be connected to anchor rods anchored in the soil layer behind the retaining members, or internal support members can be set between the round steel tube purlins on two opposite sides of the foundation pit to constrain the retaining members. Therefore, the stability of the round steel tube purlins is crucial to ensuring the safety of the entire foundation pit, and the displacement of the round steel tube purlins needs to be monitored at all times.

[0003] The prior art generally uses a displacement sensor and a data acquisition terminal used in conjunction with it to perform monitoring work, that is, the displacement sensor is installed on the round steel tube purlin, and the data acquisition terminal receives the displacement signal emitted by it and displays it for monitoring. If it is necessary to monitor the displacement changes of different horizontal positions on the round steel tube purlin, the displacement sensor must be removed from its original fixed position and then fixed to a new monitoring position; in this way, the entire process of disassembling and then installing the displacement sensor is slow and time-consuming, and the displacement sensor cannot be quickly changed on the round steel tube purlin.

[0004] Therefore, it is extremely important to propose a displacement monitoring device suitable for round steel tube purlins, which can enable the displacement sensor to quickly change position on the round steel tube purlins, so as to realize displacement monitoring of different horizontal positions on the round steel tube purlins.
