DETAILED DESCRIPTION

[0022] The road and bridge settlement detection device in this embodiment is as follows: Figure 1-3 The device shown includes a reference base 1, a detection base 4, a reference liquid storage cylinder 2 and a measuring cylinder 5.

The bottom of the reference liquid storage cylinder 2 is fluid-conducted with a liquid outlet pipe 3, and the bottom of the measuring cylinder 5 is fluid-conducted with a liquid inlet pipe 6. The liquid inlet pipe 6 and the liquid outlet pipe 3 are fluid-conducted. The reference liquid storage cylinder 2 is filled with liquid, and the liquid level in the reference liquid storage cylinder 2 and the liquid level in the measuring cylinder 5 are in the same horizontal plane. A fixed pile 11 is fixedly connected to the bottom of the reference base 1; and a supporting leg 13 is fixedly connected to the bottom of the detection base 4. By setting the reference liquid storage cylinder 2 and the measuring cylinder 5, and connecting the two through a pipeline, using the principle of a communicating vessel, the water level in the reference liquid storage cylinder 2 and the measuring cylinder 5 is the same, and the measuring cylinder 5 at different positions moves with the strata at each position, so that the settlement amount at each position can be quickly detected.

[0023] like Figure 2As shown, a support frame 7 is installed on the top of the reference base 1, and the top of the side wall of the reference liquid storage cylinder 2 is connected to the support frame 7; a fixed ring 8 is coaxially sleeved on the top of the reference liquid storage cylinder 2, and the inner diameter of the fixed ring 8 is larger than the outer diameter of the reference liquid storage cylinder 2. First rotating shafts 9 are fixedly installed on both sides of the reference liquid storage cylinder 2, and two first rotating shafts 9 penetrate the fixed ring 8 and are rotatably connected to the fixed ring 8. In the horizontal plane passing through the axis of the first rotating shaft 9: second rotating shafts 10 are fixedly connected on both sides of the fixed ring 8, and the second rotating shafts 10 are perpendicular to the first rotating shaft 9. The two second rotating shafts 10 are rotatably connected to the support frame 7 respectively. By setting the support frame 7, the fixed ring 8, the first rotating shaft 9, and the second rotating shaft 10, the reference base 1 can swing freely, ensuring that after the reference base 1 changes, the reference liquid storage cylinder 2 can still maintain a vertical downward state, thereby improving the accuracy of measurement; a hose 12 is installed between the liquid outlet pipe 3 and the reference liquid storage cylinder 2; a first scale line is arranged on the side wall of the reference liquid storage cylinder 2 along its height direction.

[0024] like Figure 2-3 As shown, a ball seat 14 is fixedly installed on the top of the detection base 4, and a ball head 15 is movably connected in the ball seat 14. The ball head 15 is tightly fitted in the ball seat 14, and the bottom end of the measuring tube 5 is connected to the ball head 15, and the liquid inlet pipe 6 is fluid-connected with the measuring tube 5; the ball head 15 is a hollow ball, one end of the measuring tube 5 is inserted into the ball head 15, and a second liquid inlet hole 17 is provided on the bottom of the ball head 15, and a first liquid inlet hole 16 that is fluid-connected with the second liquid inlet hole 17 is provided on the bottom of the ball seat 14, and the liquid inlet pipe 6 is fluid-connected with the first liquid inlet hole 16, and the bottom of the measuring tube 5 is fluid-connected with the hollow ball head 15, and a first annular scale line is provided on the outer wall of the ball head 15, and the first annular scale line is connected to the first telescopic The tube 501 is coaxially arranged; the tube walls of the first telescopic tube 501 and the second telescopic tube 502 are both provided with second annular scale lines, and the second annular scale lines are coaxially arranged with the first telescopic tube 501 and the second telescopic tube 502. By arranging the ball seat 14 and the ball head 15, the angle of the measuring tube 5 relative to the ground can be adjusted. When the angle of the detection base 4 changes with the ground, the measuring tube 5 can be adjusted and be in a vertical state, which is beneficial to improve the detection accuracy. Secondly, in conjunction with the scale lines arranged on the ball head 15, when the measuring tube 5 is adjusted to a vertical state, the relative position of the ball head 15 and the base 4 changes. In conjunction with the scale lines on the ball head 15, the angle change of the settlement can be judged.

[0025] like Figure 3 As shown, the measuring tube 5 includes a first telescopic tube 501 and a second telescopic tube 502 . The bottom end of the first telescopic tube 501 is inserted into the ball head 15 , and the second telescopic tube 502 is slidably fitted in the first telescopic tube 501 .

[0026] Working principle: Fix the reference base 1 with the fixed pile 11 on the ground at the position for setting the reference point, and ensure that the position of the reference base 1 is stable and reliable. Install the detection base 4 according to the designed road and bridge settlement detection point. The detection base 4 can be set to multiple, such as Figure 1 As shown, the reference liquid storage cylinder 2 is then installed on the reference base 1 through the support frame 7, and the reference liquid storage cylinder 2 is connected to each measuring cylinder 5 through a pipeline. This device is suitable for flat roads or bridge decks, and can also be used for road and bridge measurements with a smaller slope.

[0027] In the initial state, water is added to the reference liquid storage cylinder 2, and the water flows into the measuring cylinder 5 through the pipeline. Finally, the liquid level in the reference liquid storage cylinder 2 and the liquid level in the measuring cylinder 5 are at the same height. The scale line position of the liquid level in the reference liquid storage cylinder 2 and the scale line position of the liquid level in the measuring cylinder 5 are recorded and recorded.

[0028] As the stratum moves, when settlement occurs, it will synchronously drive the detection base 4 and the measuring tube 5 to move synchronously. When testing again, water is added to the reference liquid storage tube 2 in the same way. In order to ensure the accuracy of the detection, the reference base 1 can be tested before each test to determine whether the reference position has settled. Water enters the measuring tube 5 through the pipeline, and water is continuously added until the water level in the reference liquid storage tube 2 is the same as the position recorded for the first time. The measuring tube 5 settles as the stratum settles, and the liquid level height remains unchanged, but the height of the measuring tube 5 changes, causing the scale position to change. The settlement value can be obtained by comparing the positions of the scales where the liquid levels on both sides are located.

[0029] When the measuring tube 5 is tilted, the plane of the liquid level in the measuring tube 5 is not parallel to the plane of the annular scale lines on the measuring tube 5. At this time, adjust the angle of the measuring tube 5 until the liquid level is parallel to the scale lines, and judge the angle change of the formation settlement by observing the annular scale lines on the ball head 15.

[0030] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
