When the side slope is deformed, the tension sensor 5 can transmit information to the control center when the tension sensor is subjected to the tension of the pull wire 62 to displace, the deformation condition of the lattice type anchor rod retaining wall support can be known in real time, and the deformation condition of the side slope support can be accurately and visually monitored. The stress meter 1 is arranged in the reinforced concrete frame 2, so that the change of the internal stress of the reinforced concrete frame 2 can be conveniently monitored, and the structural condition of the reinforced concrete frame 2 can be better monitored.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
