Description

Technical Field

[0001] The invention discloses a surface settlement monitoring system for a tunnel passing through the ground, which is used for monitoring the surface settlement of a tunnel passing through the ground and belongs to the technical field of settlement monitoring systems. Background Art

[0002] The purpose of surface settlement monitoring during tunneling is to ensure the safety of tunnel construction, structural stability, and protection of the surrounding environment and existing buildings. This includes: By monitoring surface settlement, potential soil movement or structural deformation during construction can be promptly detected, allowing measures to prevent accidents; obtaining monitoring data helps assess the stability of the tunnel structure, ensuring that the tunnel can withstand the expected loads during construction and operation; analyzing settlement data allows for the prediction of future settlement trends, allowing preventive measures to be taken in advance to avoid structural damage caused by excessive settlement; and tunnel construction may impact the surrounding soil, groundwater, vegetation, and buildings. Settlement monitoring helps assess and control these impacts, protecting the environment, and more.

[0003] Although there are devices for monitoring ground settlement under tunnels in the prior art, there are the following technical problems:

[0004] 1. It is impossible to accurately inspect and monitor multiple points where settlement monitoring is required;

[0005] 2. The monitoring efficiency of multiple points is low, or multiple devices are required to monitor simultaneously, resulting in high monitoring costs. Utility Model Content

[0006] The purpose of the utility model is to provide a tunnel under the ground settlement monitoring system to solve the problem that the existing technology cannot accurately carry out inspection and monitoring of multiple points that need to be monitored for settlement.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A tunnel underpass surface settlement monitoring system includes a settlement monitoring terminal, a network unit and a user terminal that receives data monitored by the settlement monitoring terminal. The settlement monitoring terminal includes a bracket arranged on both sides of the tunnel underpass surface, two horizontal transverse guide rails arranged on the bracket and two horizontal longitudinal guide rails slidably arranged on the horizontal transverse guide rails via a first moving mechanism, a ranging sensor arranged on the horizontal longitudinal guide rails via a second moving mechanism, and at least one horizontal transverse guide rail and a horizontal longitudinal guide rail are respectively provided with multiple horizontal transverse monitoring point sensing structures and horizontal longitudinal monitoring point sensing structures. The first moving mechanism cooperates with the horizontal transverse monitoring point sensing structure, and the second moving mechanism cooperates with the horizontal longitudinal monitoring point sensing structure.

[0009] Furthermore, the first moving mechanism includes pulleys A respectively provided on the two horizontal transverse guide rails, a mounting plate A provided on the pulleys A of each horizontal transverse guide rail, a drive motor A provided on the mounting plate A for driving the pulleys A to move, and an elastic pressure structure A provided on the mounting plate A;

[0010] The second moving mechanism includes a pulley B arranged on two horizontal longitudinal guide rails, a mounting plate B arranged on the pulley B, a driving motor B arranged on the mounting plate B to drive the pulley B to move, and an elastic pressure structure B arranged on the mounting plate B.

[0011] Furthermore, T-shaped slide grooves are provided on the bottoms of the horizontal transverse guide rail and the horizontal longitudinal guide rail;

[0012] The horizontal transverse monitoring point sensing structure and the horizontal longitudinal monitoring point sensing structure respectively include a T-bolt that slides with the T-shaped slide groove, a nut and a mounting plate C arranged on the T-bolt, and a flexible sensor with a transmitter is arranged on the mounting plate C. The flexible sensor is subjected to the pressing force of the elastic pressure structure A or the elastic pressure structure B to provide signal feedback.

[0013] Furthermore, the elastic pressure structure A and the elastic pressure structure B respectively include a connecting rod A arranged on the mounting plate A or the mounting plate B, a groove body is provided on one end of the bottom of the connecting rod A, a return spring and a connecting rod B with a U-shaped head connected to the return spring are provided in the groove body, a rotating shaft is provided on the U-shaped head of the connecting rod B, and a pulley C is provided on the rotating shaft.

[0014] Furthermore, a convex groove is provided on one side of the bottom of the mounting plate B located between the horizontal longitudinal rails;

[0015] The distance measuring sensor is arranged in the convex groove to measure the distance between the convex groove and the ground surface.

[0016] Furthermore, the pulley C is covered with a rubber protective sleeve.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] First, the utility model sets a horizontal transverse monitoring point sensing structure and a horizontal longitudinal monitoring point sensing structure on the horizontal transverse guide rail and the horizontal longitudinal guide rail, and then drives the horizontal longitudinal guide rail and the ranging sensor to move by the first moving mechanism and the second moving mechanism to cooperate with the horizontal transverse monitoring point sensing structure and the horizontal longitudinal monitoring point sensing structure. Not only can the feedback signals from the horizontal transverse monitoring point sensing structure and the horizontal longitudinal monitoring point sensing structure be used to accurately determine the settlement monitoring point of the ranging sensor, but it also facilitates large-area back-and-forth inspection and detection without the need for multiple monitoring devices, thereby reducing monitoring costs and improving monitoring efficiency.

[0019] Second, when the first moving mechanism and the second moving mechanism in the present invention move, the elastic pressure structure A and the elastic pressure structure B move synchronously. When they pass through the horizontal transverse monitoring point sensing structure and the horizontal longitudinal monitoring point sensing structure, a pressing force is applied thereto to send a signal, thereby accurately performing horizontal transverse and horizontal longitudinal positioning, thereby ensuring that the ranging sensor performs settlement monitoring at the specified position, thereby improving the accuracy of the monitoring position.

[0020] 3. The horizontal transverse monitoring point sensing structure and the horizontal longitudinal monitoring point sensing structure in the present invention are slidably matched with T-shaped slideways via T-shaped bolts, making it easy to adjust their positions according to actual needs. In addition, a flexible sensor is provided on the mounting plate C, so that the elastic pressure structure B can easily press the flexible sensor and cause the flexible sensor to be subjected to force and feedback a signal to the user end.

[0021] Fourth, when the elastic pressure structures A and B in the present invention pass through the flexible sensor, they are affected by the thickness of the flexible sensor, causing the pulley C and the connecting rod B to press the return spring to contract. At the same time, the return spring presses the flexible sensor to conduct feedback signals to the user end. This not only reduces the wear of the pulley C and the damage to the flexible sensor, but also enables accurate positioning of the ranging sensor.

[0022] Fifth, the utility model sets the distance measuring sensor in the convex groove, which is not only conducive to measuring the distance between it and the ground surface for the user to perform multiple measurements and comparisons, but also has the effect of dustproof and waterproof;

[0023] 6. The present invention provides a rubber protective sleeve on the pulley C to further protect the pulley C and the flexible sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Example 1

[0039] In order to solve the problem that the existing technology cannot accurately inspect and monitor multiple points that need to be monitored for settlement. Figure 1-5 As shown, a tunnel underpass settlement monitoring system is provided, including a settlement monitoring terminal, a network unit, and a user terminal that receives data monitored by the settlement monitoring terminal. The settlement monitoring terminal 1 includes a bracket 2 arranged on both sides of the tunnel underpass, two horizontal transverse guide rails 3 arranged on the bracket 2, and two horizontal longitudinal guide rails 4 slidably arranged on the horizontal transverse guide rails 3 via a first movable mechanism 8. A ranging sensor 5 is arranged on the horizontal longitudinal guide rails 4 via a second movable mechanism 9. At least one horizontal transverse guide rail 3 and horizontal longitudinal guide rail 4 is respectively provided with a plurality of horizontal transverse monitoring point sensing structures 6 and horizontal longitudinal monitoring point sensing structures 7. The first movable mechanism 8 cooperates with the horizontal transverse monitoring point sensing structures 6, and the second movable mechanism 9 cooperates with the horizontal longitudinal monitoring point sensing structures 7. The first movable mechanism 8 and the second movable mechanism 9 can be controlled remotely or electrically connected.

[0040] In practice, the bracket 2 is installed on both sides of the tunnel under the ground to ensure that the subsequent ranging sensor 5 will not sink with the ground surface, and the two horizontal transverse guide rails 3 are installed on the bracket 2, and the first moving mechanism 8 is installed on the two horizontal transverse guide rails 3. After installation, the two horizontal longitudinal guide rails 4 are installed on the second moving mechanism 8, and then the ranging sensor 5 is installed on the two horizontal longitudinal guide rails 4. At the same time, multiple horizontal transverse monitoring point sensing structures 6 and horizontal longitudinal monitoring point sensing structures 7 are respectively installed on the horizontal transverse guide rails 3 and the horizontal longitudinal guide rails 4. When performing settlement monitoring at a specified position, the first moving mechanism 8 is controlled to move to the position of a specified horizontal transverse monitoring point sensing structure 6, and the second moving mechanism is controlled to move to the position of a specified horizontal longitudinal monitoring point sensing structure 7. The user end will receive the feedback signals from the horizontal transverse monitoring point sensing structure 6 and the horizontal longitudinal monitoring point sensing structure 7 through the network unit transmission, and the ranging sensor 5 can be positioned. After positioning, the current distance data measured in real time by the ranging sensor 5 can be read or the ranging sensor 5 can be started to measure the distance to obtain the measured distance data. This embodiment sets a horizontal transverse monitoring point sensing structure and a horizontal longitudinal monitoring point sensing structure on the horizontal transverse guide rail and the horizontal longitudinal guide rail, and then uses the first moving mechanism and the second moving mechanism to drive the horizontal longitudinal guide rail and the ranging sensor to move to cooperate with the horizontal transverse monitoring point sensing structure and the horizontal longitudinal monitoring point sensing structure. Not only can the points monitored by the ranging sensor be accurately determined through the signals fed back by the horizontal transverse monitoring point sensing structure and the horizontal longitudinal monitoring point sensing structure, but it also facilitates large-area back-and-forth patrol inspections without the need for multiple monitoring equipment, thereby reducing monitoring costs and improving monitoring efficiency.

[0041] Example 2

[0042] Based on Example 1, the first moving mechanism 8 includes pulleys A10 respectively arranged on the two horizontal transverse guide rails 3, a mounting plate A11 arranged on the pulley A10 of each horizontal transverse guide rail 3, a drive motor A12 arranged on the mounting plate A11 for driving the pulley A10 to move, and an elastic pressure structure A13 arranged on the mounting plate A11; the second moving mechanism 9 includes a pulley B14 arranged on the two horizontal longitudinal guide rails 4, a mounting plate B15 arranged on the pulley B14, a drive motor B29 arranged on the mounting plate B15 for driving the pulley B14 to move, and an elastic pressure structure B16 arranged on the mounting plate B15.

[0043] The drive motor A12 and the drive motor B29 drive the pulley A10 and the pulley B14 to move through transmission methods such as gears or belts. The mounting plate A11 and the mounting plate B15 are set on the pulley A10 and the pulley B14 through connecting parts, such as a sleeve that cooperates with the rotation of the pulley, and a support rod set on the sleeve. Of course, other connection methods in the existing technology are also possible.

[0044] When the driving motor A12 and the driving motor B29 in the first moving mechanism and the second moving mechanism in this embodiment respectively drive the moving pulley A10 and the pulley B14 to move, the mounting plate A11 and the mounting plate B15 on the pulley A10 and the pulley B14 and the elastic pressure structure A and the elastic pressure structure B on the mounting plate A11 and the mounting plate B15 move synchronously. When passing through the horizontal transverse monitoring point sensing structure and the horizontal longitudinal monitoring point sensing structure, the elastic pressure structure A and the elastic pressure structure B apply pressing force to them and send a signal, so that the ranging sensor 5 can be accurately positioned horizontally and vertically to ensure that the ranging sensor performs settlement monitoring at the specified position, thereby improving the accuracy of the monitoring position.

[0045] Example 3

[0046] On the basis of Example 2, a T-shaped groove 17 is provided on the bottom of the horizontal transverse guide rail 3 and the horizontal longitudinal guide rail 4; the horizontal transverse monitoring point sensing structure 6 and the horizontal longitudinal monitoring point sensing structure 7 respectively include a T-shaped bolt 18 that slides in cooperation with the T-shaped groove 17, a nut 19 and a mounting plate C20 arranged on the T-shaped bolt 18, and a flexible sensor 30 with a transmitter (which can have its own battery or an external power supply) is provided on the mounting plate C20. The flexible sensor 30 is subjected to the pressing force of the elastic pressure structure A13 or the elastic pressure structure B16 to provide signal feedback.

[0047] In practice, the T-bolt 18 is fixed to the T-slot 17 by the nut 19 according to the position where settlement monitoring is required. After fixation, the elastic pressure structure A13 or the elastic pressure structure B16 passes through the flexible sensor 30 on the corresponding mounting plate C20 and applies pressure to the flexible sensor 30, and the flexible sensor 30 is conducted to feedback the signal to the user end.

[0048] Example 4

[0049] Based on Example 3, the elastic pressure structure A13 and the elastic pressure structure B16 respectively include a connecting rod A21 arranged on the mounting plate A11 or the mounting plate B15, and a groove body 22 is provided on the bottom end of the connecting rod A21, and a return spring 23 and a connecting rod B24 with a U-shaped head connected to the return spring 23 are provided in the groove body 22, a rotating shaft 25 is provided on the U-shaped head of the connecting rod B24, and a pulley C26 is provided on the rotating shaft 25.

[0050] In practice, when the reset spring 23 is in the reset state, its pulley C26 can just contact the mounting plate C20. When passing through the flexible sensor 30 thereon, the pulley C26 rotates synchronously. The thickness of the flexible sensor 30 will cause the pulley C26 to apply pressure to the pulley C26 and the connecting rod B24 when passing through the connecting rod B, and compress the reset spring 23. At the same time, the reset action of the reset spring presses the flexible sensor to conduct the feedback signal to the user end, which is not only not easy to wear the pulley C, not easy to damage the flexible sensor, but also can achieve precise positioning of the ranging sensor.

[0051] Example 5

[0052] Based on Example 4, a protruding groove 27 is provided on one side of the bottom of the mounting plate B15 located between the horizontal longitudinal guide rails 4; the distance sensor 5 is disposed within the protruding groove 27 to measure the distance between the sensor and the ground surface. Placing the distance sensor within the protruding groove not only facilitates measuring the distance between the sensor and the ground surface for multiple measurements and comparisons by the user, but also provides dust and water protection. Of course, in practice, the distance sensor 5 can also be placed within other sensors used for settlement monitoring.

[0053] Example 5

[0054] On the basis of embodiment 4, the pulley C26 is covered with a rubber protective sleeve 28. The pulley C is covered with a rubber protective sleeve to further protect the pulley C and the flexible sensor.
