[0033] The angle display assembly 7 is suitable for showing the inclination angle of the bridge body 1;

[0034] The subsidence display assembly 8 is suitable for the subsidence range of the pier body 1. When in use, the two arc-shaped bases 2 are assembled by bolts, are sleeved on the outside of the measured pier body 1 and are connected with the ground. Then, the positioning clamps 3 are fixedly installed on the pier body and are arranged above the two arc-shaped bases 2. The supporting clamps 4 are installed on the positioning clamps 3 through the leveling assembly 5 and can be leveled, so that the tilt display assembly 6 arranged on the supporting clamps 4 is kept horizontal. When the pier body 1 appears subsidence tilt, the supporting clamps 4 also synchronously descend and tilt, so that the workers can clearly and accurately observe the slight tilt of the pier body 1 under the control of the tilt display assembly 6. The angle display assembly 7 can display the tilt angle of the pier body 1 after the workers understand the tilt direction of the pier body 1, and ensures that the tilt angle data of the pier body 1 is accurately displayed. Under the control of the subsidence display assembly 8, the workers can be warned when the subsidence value of the pier body 1 is too large, so that the technical problems that the existing bridge monitoring personnel cannot obtain the bridge subsidence information in time and cannot take safety measures in the first time are solved.

[0035] Optionally, the tilt display assembly 6 comprises two circular-arc sliding boxes 9 symmetrically fixed on the top of the supporting clamps 4 and communicated with each other, two balls 10 arranged in the two circular-arc sliding boxes 9 respectively, and two dustproof cover plates 11 fixed on the top of the two circular-arc sliding boxes 9 respectively. After the two circular-arc sliding boxes 9 are installed, they are in a horizontal state, so that the two balls 10 in the two circular-arc sliding boxes 9 will not displace. The two circular-arc sliding boxes 9 are made of transparent material. When the pier body 1 appears subsidence tilt, the two circular-arc sliding boxes 9 on the supporting clamps 4 are synchronously tilted, so that the two balls 10 in the two circular-arc sliding boxes 9 are moved to the lowest position after the two circular-arc sliding boxes 9 are tilted. Then, the tilt direction of the pier body 1 can be understood by observing the position of the two balls 10. Under the control of the two dustproof cover plates 11, the two circular-arc sliding boxes 9 can be closed to prevent dust from falling into the circular-arc sliding boxes 9 and affecting the movement of the two balls 10.

When the worker observes the direction of the inclination of the pier body 1 displayed by the inclined display assembly 6, the worker can hold the control seat 19 and control the sliding block 18 to move in the annular sliding groove 17, so as to move the control seat 19 to the lowest point of the support hoop 4 after the support hoop 4 is inclined. At this time, the counterweight 21 drives the connecting rod 20 and the indicating needle 23 to remain vertical, and the control seat 19 and the angle scale 22 remain parallel to the support hoop 4.

When the bridge appears to sink, the support clamp 4 is moved downward, the plurality of indicating rods 24 are moved in the plurality of movable grooves 25, and then the sinking distance of the plurality of indicating rods 24 is observed by the staff under the cooperation of the plurality of scale grooves 28, so as to understand the sinking distance of the pier body 1 in different directions. When the sinking value of the pier body 1 is too large, the pressing plate and the contact 27 below it are close to the contact 27 on one of the arc-shaped bases 2, and when the two contacts 27 are in contact, an alarm signal is sent to the staff through the alarm device.

After the two arc-shaped bases 2 are assembled and arranged outside the pier body 1, the plurality of insertion rods 29 on the plurality of arc-shaped bases 2 are inserted into the ground at the position of the pier body 1, so as to fix the two arc-shaped bases 2 above the ground and leave a gap between the two arc-shaped bases 2 and the ground, facilitating the movement of the plurality of indicating rods 24.

[0041] Optionally, the two circular arc-shaped sliding boxes 9 and the two balls 10 are made of glass. The glass balls 10 and the surfaces of the circular sliding boxes are smooth, so as to greatly reduce the resistance of the balls 10 rolling in the circular arc-shaped sliding boxes 9, and the balls 10 can roll in the circular arc-shaped sliding boxes 9 when the two circular arcs are slightly inclined.
