Description

Technical Field

[0001] This application belongs to the field of tunnel construction monitoring technology, specifically relating to a tunnel construction deformation monitoring device. Background Technology

[0002] In modern transportation infrastructure construction, tunnel engineering, due to its unique spatial structure and complex geological environment, makes the stability of the tunnel itself crucial to project safety and the safety of construction workers' lives and property during construction. Tunnels are highly susceptible to deformation under excavation, support, and external loads. Once the deformation exceeds a critical value, it can lead to serious accidents such as collapse and water seepage. Therefore, real-time and accurate monitoring of deformation during tunnel construction is a key aspect of ensuring the smooth progress of the project.

[0003] Currently, common methods for monitoring tunnel deformation include manual inspection, total station measurement, and fiber optic monitoring. Manual inspection relies on construction personnel periodically checking for superficial phenomena such as cracks and water leakage in the tunnel walls. This method suffers from long monitoring cycles, strong subjectivity, and difficulty in capturing subtle deformations, making it unable to detect potential hazards in a timely manner. While total station measurement can achieve a certain level of displacement monitoring accuracy, its complex equipment setup and susceptibility to environmental interference make it difficult to meet the real-time monitoring needs of dynamic tunnel construction. Although fiber optic monitoring technology offers advantages such as high precision and distributed monitoring, its high cost and extremely demanding installation and maintenance requirements limit its widespread application in ordinary tunnel construction. Utility Model Content

[0004] The purpose of this application is to provide a tunnel construction deformation monitoring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] Tunnel construction deformation monitoring device, including:

[0007] The tunnel body and the monitoring components installed inside the tunnel body, as well as the alarm installed on the inner wall of the tunnel body;

[0008] The monitoring component includes two base plates, each with a mounting base fixedly connected to it. An arc-shaped rod is rotatably connected to one mounting base, and a groove is provided on the arc-shaped rod. A spring is installed inside the groove. An arc-shaped rod is rotatably connected to the other mounting base, and a pin is installed at one end of the arc-shaped rod. A top plate is fixedly connected to the arc-shaped rod and the arc-shaped rod. A contact switch is installed at the top of the inner side of the tunnel body.

[0009] Preferably, the bottom plates on both sides are symmetrically fixed to the inner wall of the tunnel body, and the mounting seats on both sides are symmetrically arranged.

[0010] Preferably, the first arc-shaped rod and the second arc-shaped rod are arranged opposite to each other, and the first arc-shaped rod is attached to the rear side of the second arc-shaped rod.

[0011] Preferably, the spring is movably engaged inside the slide groove, the pin is disposed inside the slide groove, and the pin abuts against one end of the spring.

[0012] Preferably, the contact switch is located at the top of the junction of the first and second arc-shaped rods, and the top of the second arc-shaped rod abuts against the bottom of the contact switch.

[0013] Preferably, the top plates on both sides are attached to the inner wall of the tunnel body.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] (1) Through the fitting design of the arc rod one and arc rod two with the top plate, the subtle deformation of the tunnel body can be sensed in real time, thereby effectively avoiding the blind spots of traditional monitoring methods, accurately capturing the deformation data inside the tunnel, and providing a reliable basis for tunnel safety status assessment.

[0016] (2) It adopts a compact structure with an arc rod and a top plate fitting and a pin and groove matching, which occupies little space inside the tunnel and does not affect normal construction operations. At the same time, the mechanical transmission method does not require complicated wiring and power support, which reduces the cost of equipment installation and maintenance. It is suitable for various complex tunnel construction environments and has high practicality and environmental adaptability.

[0017] (3) Automated monitoring and alarms through mechanical structures reduce the omissions and delays of manual inspections, effectively reduce the risk of accidents such as collapse caused by deformation during tunnel construction, provide reliable safety protection for tunnel construction personnel, and significantly improve the overall safety performance of tunnel construction.

[0026] Example 1:

[0027] Please see Figures 1-2 As shown, the tunnel construction deformation monitoring device includes:

[0028] The tunnel body 1, the monitoring component 2 installed inside the tunnel body 1, and the alarm 3 installed on the inner wall of the tunnel body 1;

[0029] As can be seen from the above, before construction, the monitoring component 2 is installed inside the construction tunnel body 1. The internal deformation of the construction tunnel body 1 is monitored by the monitoring component 2. When the internal deformation of the construction tunnel body 1 occurs, the alarm 3 is activated to alert the workers inside the tunnel body 1.

[0030] Specifically, regarding the aforementioned monitoring component 2, please refer to... Figures 3-5As shown, the monitoring component 2 includes two base plates 21, and mounting bases 22 are fixedly connected to both base plates 21. An arc rod 23 is rotatably connected to one mounting base 22. A groove 24 is opened on the arc rod 23, and a spring 25 is installed inside the groove 24. An arc rod 26 is rotatably connected to the other mounting base 22. A pin 27 is installed at one end of the arc rod 26. A top plate 28 is fixedly connected to the arc rod 23 and the arc rod 26. A contact switch 29 is installed at the top of the inner side of the tunnel body 1.

[0031] As can be seen from the above, before construction, the bottom plates 21 on both sides are symmetrically installed on the inner wall of the tunnel body 1. Then, the arc rod 1 23 and arc rod 26 are respectively rotated and installed on the top of the mounting base 22 on both sides, so that the arc rod 1 23 and arc rod 26 can rotate. At this time, the top plate 28 of the top of the arc rod 1 23 and arc rod 26 is attached to the inner wall of the tunnel body 1. The pin 27 at the end of the arc rod 26 is located inside the slide groove 24. The slide groove 24 restricts the movement direction of the pin 27, so that the pin 27 can move along the direction of the slide groove 24. Subsequently, the spring 25 can return the pin 27 to the initial position.

[0032] Example 2:

[0033] refer to Figure 3 , Figure 4 and Figure 5 As shown, the bottom plates 21 on both sides are symmetrically fixed to the inner wall of the tunnel body 1, and the mounting seats 22 on both sides are symmetrically arranged. The arc rod 1 23 and the arc rod 26 are arranged opposite each other, and the arc rod 1 23 is attached to the rear side of the arc rod 26. The spring 25 is movably engaged in the inside of the slide groove 24. The pin 27 is set in the inside of the slide groove 24 and abuts against one end of the spring 25. The contact switch 29 is set at the top of the junction of the arc rod 1 23 and the arc rod 26, and the top of the arc rod 26 abuts against the bottom of the contact switch 29. The top plates 28 on both sides are attached to the inner wall of the tunnel body 1.

[0034] As can be seen from the above, during monitoring, if the tunnel body 1 does not deform, the top plate 28 at the top of the arc rod 1 23 and the arc rod 26 is attached to the inner wall of the tunnel body 1, so that the junction of the arc rod 1 23 and the arc rod 26 just abuts against the bottom of the contact switch 29; when the tunnel body 1 deforms, the deformation will squeeze the top plates 28 on both sides, causing the arc rod 1 23 and the arc rod 26 to rotate. At this time, the pin 27 moves along the direction of the slide 24, squeezing the spring 25, so that the junction of the arc rod 1 23 and the arc rod 26 can no longer abut against the bottom of the contact switch 29, thus controlling the alarm 3 to run through the contact switch 29; subsequently, the workers will process the deformation of the tunnel body 1, so that the top plates 28 on both sides will return to their original position and be tightly attached to the inner wall of the tunnel body 1, and the pin 27 will move to its initial position under the action of the spring 25, thus monitoring the deformation of the tunnel body 1 again.
