Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tunnel and underground engineering technology, and more specifically, it relates to a tunnel support device with water leakage prevention function. Background Technology
[0002] A tunnel support device with anti-leakage function is a support structure specifically designed for tunnel engineering. It is suitable for tunnel construction and operation scenarios in water-rich strata, high-permeability surrounding rock, or tunnels prone to seepage. It can effectively solve problems such as structural erosion and softening of surrounding rock caused by tunnel leakage. However, the drainage system of commonly used tunnel support devices with anti-leakage function may become blocked during use due to impurities such as mud and sand in the water flow, which is inconvenient for workers to clean and affects subsequent construction. Therefore, a new type of tunnel support device with anti-leakage function is needed. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a tunnel support device with anti-leakage function, thereby solving the problem of drainage system blockage that may occur during the use of existing tunnel support devices with anti-leakage function.
[0004] This utility model discloses a tunnel support device with anti-leakage function, which is achieved by the following specific technical means:
[0005] A tunnel support device with water-proof function includes a base plate, a support plate, and a movable frame;
[0006] The base plate has two sets of round holes on its left and right sides, and a set of fixing bolts is installed in each of the four sets of round holes on the base plate. The two sets of support plates are placed on the left and right sides of the base plate, and a set of grooves is provided on the upper side of the two sets of support plates. Two sets of hydraulic rods are installed in the grooves. A set of square holes is provided at the lower end of the two sets of support plates. A set of sliding grooves is provided on the outer side of the two sets of support plates. The two sets of movable frames are respectively installed in the sliding grooves on the outer side of the two sets of support plates, and filter plates A are fixedly connected to the lower end of the two sets of support plates.
[0007] Furthermore, a set of connecting plates is respectively installed in the upper grooves of the two sets of support plates, and a set of top plates is connected to the two sets of connecting plates. An arc-shaped plate is connected to the upper end of the top plate, and seven sets of guide grooves are provided on the arc-shaped plate.
[0008] Furthermore, a set of positioning plates is fixedly connected to the lower end of each of the two sets of support plates, and each of the two sets of positioning plates is provided with two sets of threaded holes, which are threadedly connected to the fixing bolts.
[0009] Furthermore, a set of fixed plates is fixedly connected to the inner side of each of the two sets of movable frames, and a shock-absorbing plate is connected to the outer side of the fixed plate. Five sets of guide grooves are provided on the shock-absorbing plate. A water-absorbing plate is clamped between the fixed plate and the movable frame, and the water-absorbing plate is placed on the upper side of the filter plate A.
[0010] Furthermore, a set of movable parts are respectively installed in the square holes at the lower ends of the two sets of support plates, and a drainage groove is provided on the movable parts, and a filter plate B is fixedly connected inside the drainage groove.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. By setting up a shock-absorbing plate, this utility model is advantageous because the shock-absorbing plate is connected to the outside of the fixed plate. The shock-absorbing plate is provided with five sets of guide grooves. The lower inner side of the five sets of guide grooves on the shock-absorbing plate passes through the shock-absorbing plate, which facilitates the guidance of water seeping from the tunnel sidewall to the filter plate A14 below. This avoids the disorderly diffusion of water on the surface of the support device, reduces leakage points, and at the same time facilitates the absorption plate 12 to absorb the residual water that has not been completely discharged from the guide grooves.
[0013] 2. This utility model has a water-absorbing plate installed between the fixed plate and the movable frame, which helps to absorb excess water leaking from the shock-absorbing plate. At the same time, it is convenient for staff to replace the water-absorbing plate if it is damaged.
[0014] 3. This utility model features a movable component that is fitted into a square hole at the lower end of a support plate. A drainage groove is provided on the movable component, and a filter plate B is fixedly connected inside the drainage groove. The filter plate B filters out impurities such as gravel and mud, preventing the drainage groove from becoming clogged, and the drainage groove quickly discharges the accumulated water.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] Example:
[0024] As attached Figure 1 To be continued Figure 5 As shown:
[0025] This utility model provides a tunnel support device with anti-leakage function, including a base plate 1, a support plate 2, and a movable frame 13;
[0026] Two sets of round holes are provided on the left and right sides of the base plate 1, and a set of fixing bolts 9 are respectively installed in the four sets of round holes on the base plate 1. Two sets of support plates 2 are respectively placed on the left and right sides of the base plate 1, and a set of grooves are provided on the upper side of the two sets of support plates 2. Two sets of hydraulic rods 8 are installed in the grooves. A set of square holes are provided at the lower end of the two sets of support plates 2. A set of sliding grooves are provided on the outer side of the two sets of support plates 2. Two sets of movable frames 13 are respectively installed in the sliding grooves on the outer side of the two sets of support plates 2, and filter plates A14 are fixedly connected to the lower end of the two sets of support plates 2.
[0027] Among them, such as Figure 2 As shown, a set of connecting plates 7 are respectively installed in the upper grooves of the two sets of support plates 2, and a set of top plates 3 are connected to the two sets of connecting plates 7. An arc plate 4 is connected to the upper end of the top plate 3. The arc plate 4 is provided with seven sets of guide grooves. The seven sets of guide grooves on the arc plate 4 form a clear drainage channel, which avoids the disorderly seepage of water on the surface of the support device and achieves the dual anti-leakage effect of diversion and drainage.
[0028] Among them, such as Figure 1 As shown, a set of positioning plates 10 are fixedly connected to the lower ends of the two sets of support plates 2, and two sets of threaded holes are provided on the two sets of positioning plates 10 respectively. The threaded holes are threadedly connected to the fixing bolts 9. Through the rigid threaded engagement between the fixing bolts 9 and the threaded holes, a strong pre-tightening force can be provided to ensure that the positioning plates 10 are tightly attached to the bottom plate 1. This is beneficial for evenly distributing the vertical pressure and lateral force borne by the support plates 2, and avoiding the device from tilting or loosening due to excessive force at a single point. It is suitable for complex geological load environments in tunnel construction.
[0029] Among them, such as Figure 4 and Figure 5As shown, a set of fixed plates 11 are fixedly connected to the inner sides of the two sets of movable frames 13, and a shock-absorbing plate 5 is connected to the outer side of the fixed plate 11. The shock-absorbing plate 5 is provided with five sets of guide grooves. A water-absorbing plate 12 is clamped between the fixed plate 11 and the movable frame 13. The water-absorbing plate 12 is placed on the upper side of the filter plate A14. A set of movable parts 6 are clamped in the square holes at the lower ends of the two sets of support plates 2, and a drainage groove is provided on the movable part 6. A filter plate B15 is fixedly connected inside the drainage groove. The filter plate B15 passes through the inner side of the lower end of the five sets of guide grooves on the shock-absorbing plate 5. 5. This facilitates the guidance of water seeping through the tunnel sidewall along the channel to the lower filter plate A14, preventing the water from spreading disorderly on the surface of the support device and reducing leakage points. At the same time, it facilitates the absorption plate 12 to absorb the residual water that has not been completely discharged from the guide channel. When the absorption plate 12 is saturated, the excess water can be discharged into the drainage channel of the movable part 6 through the pores of the filter plate A14 and the filter plate B15. The filter plate A14 and the filter plate B15 work together to intercept impurities such as mud, sand and gravel in the water, preventing the drainage channel of the movable part 6 from being blocked and extending the service life of the anti-leakage component.
[0030] The specific usage and function of this embodiment are as follows:
[0031] like Figures 1 to 5 As shown, in this utility model, the seven sets of guide grooves on the arc plate 4 form a clear drainage channel, which avoids the disorderly seepage of water on the surface of the support device and achieves a dual anti-leakage effect of dredging and diversion. The rigid threaded engagement of the fixing bolt 9 and the threaded hole can provide a strong pre-tightening force, ensuring that the positioning plate 10 and the bottom plate 1 are tightly fitted. This is conducive to evenly dispersing the vertical pressure and lateral force borne by the support plate 2, and avoiding the device from tilting or loosening due to excessive force at a single point. It is suitable for complex geological load environments in tunnel construction.
[0032] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
