Figure 3 The enlarged structure of the floating rod part of the road subsidence measuring device provided by the embodiment of the present invention is shown. Figure 4 FIG. 2 shows an enlarged structure of a cylinder portion of a road subsidence measuring device provided by an embodiment of the present invention. Figure 5 FIG. 2 shows an enlarged structure of a slide plate portion of a road subsidence measuring device provided by an embodiment of the present invention.

[0037] Combination Figures 1 to 5 It can be seen that the present invention provides a road subsidence measuring device, including a bridge deck 1 supported above a road surface to be measured and a driving assembly connected to the bridge deck 1; wherein the driving assembly is used to drive the bridge deck 1 to move forward and backward along the road surface to be measured above the road surface to be measured; a surveying assembly is arranged on the bridge deck 1, the surveying assembly includes a surveying rod 17 and a surveying paper 5 corresponding to the surveying rod 17, and the surveying rod 17 is movably connected to the bridge deck 1; and the surveying rod 17 moves with the bridge deck 1, and rises and falls synchronously with the road surface to be measured below the bridge deck 1.

[0038] In actual use, the driving component can be set on both sides of the sewage pipe backfill area (the road surface to be measured). The driving component drives the entire device to move forward, and the surveying rod 17 can automatically float following the changes in the settlement of the road surface, and draw a concave curve on the surveying paper 5, corresponding to the settlement of the road. By drawing the surveying curve on the surveying paper 5, the road settlement can be understood more accurately and comprehensively, and continuous settlement change records can be achieved; and, through the reciprocating movement of the entire device along the sewage pipe backfill area, the road settlement in the sewage pipe backfill area can be monitored and measured comprehensively, accurately, and multiple times.

[0039] For the driving assembly, in order to realize the driving of the bridge deck 1 by the driving assembly, the driving assembly may include two side support plates 2 fixedly installed at the bottom of both ends of the bridge deck 1, and moving wheels 3 are rotatably installed on the side support plates 2. The moving wheels 3 can be driven to rotate by direct motor drive, thereby realizing the movement of the entire equipment.

[0040] Combination Figure 1 and Figure 3 As shown, in order to enable the surveying rod 17 to move up and down with the ups and downs of the road surface under the bridge deck 1, a transverse groove 9 can be opened horizontally on the bridge deck 1, a slider 10 is slidably connected in the transverse groove 9, a floating rod 11 is movably inserted on the slider 10, a floating wheel 13 is installed at the bottom of the floating rod 11 through a mounting seat 12, and the floating wheel 13 runs on the road surface to be measured; and the surveying rod 17 is fixedly connected to the top of the floating rod 11.

[0041] It should be noted that, in actual use, the lateral position of the floating wheel 13 on the road surface to be measured can be moved by changing the position of the slider 10 in the transverse groove 9, thereby achieving settlement measurement of other positions of the road surface to be measured.

[0042] Furthermore, in order to improve the supporting stability of the floating rod 11, a lower support spring 14 can be mounted on the floating rod 11. The lower support spring 14 is limited between the mounting seat 12 and the slider 10. The lower support spring 14 provides auxiliary support to the floating rod 11 and can have a certain buffering effect.

[0043] In actual use, the moving wheels 3 are located on both sides of the sewage pipe backfill area (the road surface to be measured), and the floating wheels 13 are located on the road surface of the sewage pipe backfill area. The moving wheels 3 drive the entire device to move forward, and the floating wheels 13 can automatically float following the changes in road surface settlement to detect road settlement. Through the reciprocating motion of the entire device along the sewage pipe backfill area, the road settlement in the sewage pipe backfill area can be monitored and measured comprehensively, accurately and multiple times.

[0044] Specifically, when the road sinks, the floating wheel 13 will move downward, and then drive the surveying rod 17 to move downward through the floating rod 11. Since the surveying paper 5 on the two reels 4 is also in motion, the downward movement of the surveying rod 17 will draw a concave curve on the surveying paper 5 (a straight line when it has not sunk). Corresponding to the road sinking, by drawing the surveying curve on the surveying paper 5, the road sinking situation can be understood more accurately and comprehensively, and continuous records of settlement changes can be achieved.

[0045] In addition, in order to realize the connection between the floating rod 11 and the surveying rod 17 , a top cabinet 15 is fixed on the top of the floating rod 11 , a moving block 16 is slidably connected up and down in the top cabinet 15 , and the surveying rod 17 is inserted into the moving block 16 .

In actual use, the position of the moving block 16 in the top cabinet 15 can be adjusted by rotating the knob, so as to adjust the height of the surveying rod 17.

[0047] In another specific embodiment of the present invention, Figure 4 As shown, in order to adjust the relative height between the surveying rod 17 and the surveying paper 5, a cylinder 20 can also be arranged on the top of the top cabinet 15, and the output end of the cylinder 20 extends to the inside of the top cabinet 15 and is fixedly connected to the moving block 16. In actual use, the electric control does not require manual regulation, and the cylinder 20 drives the moving block 16 to move up and down in the top cabinet 15, thereby adjusting the height of the surveying rod 17.

[0048] It should be noted that a top cabinet 15 is fixedly installed on the top of the floating rod 11, and a moving block 16 is set in the top cabinet 15 for sliding up and down. The surveying rod 17 is inserted in the moving block 16. The moving block 16 can adjust the position up and down through the screw rod 19 or the cylinder 20, thereby controlling the up and down position of the surveying rod 17 and making full use of the space of the surveying paper 5.

[0049] In addition, if Figure 5 As shown, a slide plate 21 is fixedly connected to the end of the surveying rod 17 away from the surveying paper 5, and the slide plate 21 is slidably connected to the fixing plate 22, and the fixing plate 22 is fixedly connected to the top of the bridge deck 1. Furthermore, a T-shaped slider 23 is provided on the slide plate 21, and a T-shaped slot 24 corresponding to the T-shaped slider 23 is provided on the fixing plate 22; in this way, the entire slider 10 can also be adjusted left and right to monitor the settlement of different positions on the road surface, and the position of the surveying rod 17 is not affected during the adjustment process.

[0051] The two ends of the surveying and mapping paper 5 are fixedly connected with clamping posts 6, and the outer walls of the two reels 4 are provided with post grooves 7 adapted to the clamping posts 6, and the two clamping posts 6 are respectively clamped in the corresponding post grooves 7. In actual use, after one end of the surveying and mapping paper 5 is fixed on the reel 4 by the clamping post 6, it is wound on the reel 4, and the other end is fixed to the other reel 4 after winding.

[0052] In the present invention, the two reels 4 are rotatably mounted on the bridge plate 1 via a rotating shaft, and the two rotating shafts are connected via a synchronous belt 25, so that the two reels 4 can rotate synchronously; specifically, the rotation of the two reels 4 can be achieved by using a motor to drive a rotating shaft to rotate.

[0053] In addition, if Figure 1 As shown, a paper pad 8 is fixed on the bridge deck; wherein the paper pad 8 is located between the two reels 4 and is used to support the surveying and mapping paper 5 suspended between the two reels 4 .
