The wire drop 6 is suspended on the roof 1 of the tested structure, paying-off holes are respectively formed in corresponding positions of the first floor slab 2, the underground first floor slab 3 and the underground second floor slab 4 of the tested structure, and the wire drop 6 sequentially penetrates through the paying-off holes of the first floor slab 2, the underground first floor slab 3 and the underground second floor slab 4 and hangs into the barrel 11 of the underground third floor 5. Preferably, the barrel 11 is filled with engine oil, and plays a role in damping the swing of the wire weight 6.

In this embodiment, the number of the conductive wires 8 is 8, and each two conductive wires 8 are in a group, and the total number of the conductive wires is 4. Each group of conductive wires 8 are arranged at intervals of 45 degrees in a crossing way to form a Chinese character 'mi'. The 4 groups of conductive wires 8 are erected around the paying-off hole in the directions of east, south, west, north, southeast, southwest, northwest and northeast respectively. The distance between each conductive wire 8 and the wire weight 6 is 1mm.

The invention also provides a monitoring method, which uses the reinforcement engineering monitoring device to measure, and comprises the following specific steps:
s1, forming paying-off holes at the four corners of a tested structure at the corresponding positions of a first floor slab, an underground first floor slab and an underground second floor slab respectively;
