When the point moves down, the benchmark 8 moves down accordingly. By observing the benchmark 8, the settlement change of this point can be known, so as to facilitate timely adjustment of the construction plan; after the monitoring of this point is completed, the benchmark 8 is moved out, and the guide rod 9 and the sliding frame 10 are moved again to transfer it to the next point, without reinstallation and disassembly, the operation is simpler and more convenient, and the progress of the project is accelerated.

The slider 7 slides in the first through slot 11 on the cross bar 1, driving the guide rod 9 to move along the cross tube, facilitating the adjustment of the position and improving the working efficiency.

[0026] According to a further optimized solution, a motor 13 is embedded in the cross bar 1, and a lead screw 14 is fixedly connected to the output shaft of the motor 13.

The end of the pointer 20 away from the connecting plate 19 faces the side with scales written on the benchmark 8. When the benchmark 8 is installed, the scale pointed by the pointer 20 is recorded. When the monitoring is completed, the scale pointed by the pointer 20 is recorded again. The difference between the two scales is the settlement amount, which is convenient for construction personnel to refer to.
