Description

Technical Field

[0001] This utility model relates to the field of tunnel construction, specifically a stable structure for tunnel sand layers. Background Technology

[0002] The design of stable structures for tunnels in sandy soil layers requires comprehensive consideration of factors such as geological conditions, design loads, structural form, and construction technology. By selecting appropriate support structures and grouting reinforcement measures, the stability of tunnels in sandy soil layers can be effectively improved, ensuring the safe operation and service life of the tunnels.

[0003] The stabilization structure of sandy soil layers plays a crucial role in tunnel engineering. It not only ensures the stability and safety of the tunnel but also reduces construction and maintenance costs and improves the overall performance of the tunnel. Therefore, when designing and implementing tunnel projects, the characteristics of sandy soil layers and the requirements for stabilization structures must be fully considered to ensure the smooth progress and long-term effectiveness of the tunnel project.

[0004] Existing tunnel sand layer stabilization structures generally use hydraulic support mechanisms to support the inner wall of the tunnel to achieve sand layer stabilization. However, during use and observation, it has been found that this support method is prone to problems during operation. Due to the unevenness of the inner wall of the tunnel, the hydraulic support device cannot flexibly adjust its position to support different locations, which can easily lead to inadequate support of the inner wall of the tunnel and cause safety accidents during construction.

[0005] Therefore, a tunnel sand layer stabilization structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A tunnel sand layer stabilization structure of this utility model includes a slide rail; a support frame is slidably connected to the slide rail; a sliding groove is opened on the support frame; multiple sliders are slidably connected to the sliding groove; a connecting plate is fixedly connected to the slider; a hydraulic cylinder is fixedly connected to the connecting plate; a support plate is fixedly connected to the output end of the hydraulic cylinder. By fixing the support plate to the output end of the hydraulic cylinder, the inner sidewall of the tunnel is supported when the support plate contacts the inner sidewall of the tunnel. By adjusting the position of the slider on the support frame, the support plate can support different positions of the inner sidewall of the tunnel, reducing the situation where the support effect of the inner sidewall of the tunnel is poor when it is uneven.

[0008] Preferably, a pair of auxiliary plates are hinged to the support plate; a telescopic rod is hinged to the auxiliary plate; the other end of the telescopic rod is hinged to the connecting plate. By hinged to the telescopic rod on the auxiliary plate, when the auxiliary plate contacts the inner wall of the tunnel, the telescopic rod supports the auxiliary plate and the inner wall of the tunnel, thereby increasing the contact area between the auxiliary plate and the inner wall of the tunnel and enhancing the supporting effect of the auxiliary plate on the inner wall of the tunnel.

[0009] Preferably, a pair of fixing blocks are fixedly connected to the auxiliary plate; a roller is rotatably connected between the pair of fixing blocks. By rotatably connecting the roller to the fixing blocks, the roller rolls on the inner wall of the tunnel when the auxiliary plate comes into contact with the inner wall of the tunnel, which can reduce the direct contact between the auxiliary plate and the inner wall of the tunnel, thus preventing the auxiliary plate from being scratched or damaged.

[0010] Preferably, multiple fixed columns are fixedly connected to the support plate; the fixed columns are located between a pair of auxiliary plates. By fixing multiple fixed columns to the support plate, when the fixed columns move to a designated position, the fixed columns enter the sand layer of the inner wall of the tunnel, thereby enhancing the fixing effect on the sand layer of the inner wall of the tunnel.

[0011] Preferably, a first elastic cloth is fixedly connected to the support plate; the other end of the first elastic cloth is fixedly connected to the connecting plate; the hydraulic cylinder is located inside the first elastic cloth. By fixing the first elastic cloth to the support plate, the hydraulic cylinder is covered when the first elastic cloth is stretched, which can reduce the situation where dust and debris fall around the hydraulic cylinder during the process of supporting the sand layer on the inner sidewall of the tunnel, causing the hydraulic cylinder to move and get stuck.

[0012] Preferably, a second elastic cloth is fixed between adjacent connecting plates; the second elastic cloth is located between the auxiliary plate and the support frame. By fixing the second elastic cloth between a pair of connecting plates, the support frame can be covered when the second elastic cloth is stretched, reducing the amount of dust and impurities falling into the groove opened on the support frame, which could cause the slider to move and get stuck in the groove.

[0013] The advantages of this utility model are:

[0014] 1. The tunnel sand layer stabilization structure of this utility model has a support plate fixed to the output end of a hydraulic cylinder. When the support plate contacts the inner wall of the tunnel, it supports the inner wall of the tunnel. By adjusting the position of the slider on the support frame, the support plate can support different positions of the inner wall of the tunnel, reducing the situation where the support effect of the inner wall of the tunnel is poor when the inner wall of the tunnel is uneven.

[0015] 2. The tunnel sand layer stabilization structure of this utility model has a telescopic rod hinged to the auxiliary plate. When the auxiliary plate contacts the inner wall of the tunnel, the telescopic rod supports the auxiliary plate and the inner wall of the tunnel, which can increase the contact area between the auxiliary plate and the inner wall of the tunnel and enhance the supporting effect of the auxiliary plate on the inner wall of the tunnel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a tunnel sand layer stabilization structure includes a slide rail 1; a support frame 11 is slidably connected to the slide rail 1; a groove 12 is provided on the support frame 11; multiple sliders 13 are slidably connected to the groove 12; a connecting plate 14 is fixedly connected to the slider 13; a hydraulic cylinder 15 is fixedly connected to the connecting plate 14; and a support plate 16 is fixedly connected to the output end of the hydraulic cylinder 15. When tunnel support work is required, the slide rail 1 is placed in a designated position, and then the support frame 11 is opened. When the support frame 11 moves to the designated position, the multiple sliders 13 slidably connected to the support frame 11 are opened. When the multiple sliders 13 slide in the groove 12, the connecting plate 14 moves accordingly. When the connecting plate 14 moves to the designated position, the hydraulic cylinder 15 fixed on the connecting plate 14 is activated. When the hydraulic cylinder 15 is activated, the support plate 16 fixed to the output end of the hydraulic cylinder 15 moves accordingly. When the support plate 16 moves to the designated position, the support plate 16 contacts the inner wall of the tunnel. At this time, the support plate 16 deforms to support the sand layer of the inner wall of the tunnel. By fixing the support plate 16 to the output end of the hydraulic cylinder 15, the inner wall of the tunnel is supported when the support plate 16 contacts the inner wall of the tunnel. By adjusting the position of the slider 13 on the support frame 11, the support plate 16 can support different positions of the inner wall of the tunnel, reducing the situation where the support effect of the inner wall of the tunnel is poor when it is uneven.

[0026] like Figure 2 As shown, a pair of auxiliary plates 2 are hinged to the support plate 16; a telescopic rod 21 is hinged to the auxiliary plate 2; the other end of the telescopic rod 21 is hinged to the connecting plate 14. When the auxiliary plate 2 contacts the inner wall of the tunnel, the telescopic rod 21 is compressed. When the telescopic rod 21 is compressed to a specified position, the telescopic rod 21 supports the auxiliary plate 2. When the auxiliary plate 2 is supported, the auxiliary plate 2 and the inner wall of the tunnel are in contact and support the inner wall of the tunnel. By hinged to the telescopic rod 21 on the auxiliary plate 2, the telescopic rod 21 supports the auxiliary plate 2 when it contacts the inner wall of the tunnel, thus supporting the auxiliary plate 2 and the inner wall of the tunnel. This increases the contact area between the auxiliary plate 2 and the inner wall of the tunnel, and enhances the supporting effect of the auxiliary plate 2 on the inner wall of the tunnel.

[0027] like Figure 3 As shown, a pair of fixing blocks 3 are fixedly connected to the auxiliary plate 2; a roller 31 is rotatably connected between the pair of fixing blocks 3. When the auxiliary plate 2 moves towards the inner wall of the tunnel, the roller 31 moves accordingly. When the roller 31 contacts the inner wall of the tunnel, the roller 31 rolls on the inner wall of the tunnel. When the roller 31 rolls to a designated position on the inner wall of the tunnel, the auxiliary plate 2 contacts the inner wall of the tunnel. By rotatably connecting the roller 31 to the fixing blocks 3, the roller 31 rolls on the inner wall of the tunnel when the auxiliary plate 2 contacts the inner wall of the tunnel, which can reduce the direct contact between the auxiliary plate 2 and the inner wall of the tunnel, thus reducing the possibility of scratches and damage to the auxiliary plate 2.

[0028] like Figure 4 As shown, multiple fixing columns 4 are fixedly connected to the support plate 16. The fixing columns 4 are located between a pair of auxiliary plates 2. When the support plate 16 moves to a designated position, the fixing columns 4 contact the inner wall of the tunnel. When the support plate 16 continues to move towards the inner wall of the tunnel, the fixing columns 4 contact the inner wall of the tunnel and insert into the sand layer of the inner wall of the tunnel. By fixing multiple fixing columns 4 to the support plate 16, when the fixing columns 4 move to a designated position, the fixing columns 4 enter the sand layer of the inner wall of the tunnel, thereby enhancing the fixing effect on the sand layer of the inner wall of the tunnel.

[0029] like Figure 5 As shown, a first elastic cloth 5 is fixedly connected to the support plate 16; the other end of the first elastic cloth 5 is fixedly connected to the connecting plate 14; the hydraulic cylinder 15 is located inside the first elastic cloth 5. When the hydraulic cylinder 15 is opened, it stretches the first elastic cloth 5. When the first elastic cloth 5 is stretched, it covers the hydraulic cylinder 15. By fixing the first elastic cloth 5 to the support plate 16 and covering the hydraulic cylinder 15 when the first elastic cloth 5 is stretched, it is possible to reduce the fall of dust and debris around the hydraulic cylinder 15 during the support of the sand layer on the inner wall of the tunnel, which could cause the hydraulic cylinder 15 to move and get stuck.

[0030] like Figure 5 As shown, a second elastic cloth 6 is fixed between adjacent connecting plates 14. The second elastic cloth 6 is located between the auxiliary plate 2 and the support frame 11. When the slider 13 moves, it drives the connecting plate 14 to move. When the connecting plate 14 moves, it drives the second elastic cloth 6 to move. When the second elastic cloth 6 is stretched, it covers the support frame 11. By fixing the second elastic cloth 6 between a pair of connecting plates 14, the support frame 11 can be covered when the second elastic cloth 6 is stretched, reducing the amount of dust and impurities falling into the groove 12 opened on the support frame 11, which could cause the slider 13 to move and get stuck in the groove 12.

[0031] Working principle: When tunnel support is required, slide rail 1 is placed in the designated position, and then support frame 11 is activated. When support frame 11 moves to the designated position, multiple sliders 13 slidably connected to support frame 11 are activated. As the multiple sliders 13 slide in the slide groove 12, connecting plate 14 moves accordingly. When connecting plate 14 moves to the designated position, hydraulic cylinder 15 fixed on connecting plate 14 is activated. When hydraulic cylinder 15 is activated, it drives support plate 16 fixed to the output end of hydraulic cylinder 15 to move accordingly. When support plate 16 moves to the designated position, support plate 16 contacts the inner wall of the tunnel. At this time, support plate 16 deforms to support the sand layer of the inner wall of the tunnel. When auxiliary plate 2 contacts the inner wall of the tunnel, telescopic rod 21 is compressed. When telescopic rod 21 is compressed to the designated position, telescopic rod 21 supports auxiliary plate 2. When auxiliary plate 2 is supported, the auxiliary plate 2... The auxiliary plate 2 is attached to the inner wall of the tunnel to support it. When the auxiliary plate 2 moves towards the inner wall of the tunnel, the roller 31 moves accordingly. When the roller 31 contacts the inner wall of the tunnel, it rolls on the inner wall. When the roller 31 rolls to a designated position on the inner wall of the tunnel, the auxiliary plate 2 contacts the inner wall of the tunnel. When the support plate 16 moves to a designated position, the fixed column 4 contacts the inner wall of the tunnel. When the support plate 16 continues to move towards the inner wall of the tunnel, the fixed column 4 contacts the inner wall of the tunnel and inserts into the sand layer of the inner wall of the tunnel. When the hydraulic cylinder 15 is opened, it stretches the first elastic cloth 5. When the first elastic cloth 5 is stretched, it covers the hydraulic cylinder 15. When the slider 13 moves, it drives the connecting plate 14 to move. When the connecting plate 14 moves, it drives the second elastic cloth 6 to move. When the second elastic cloth 6 is stretched, it covers the support frame 11.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
