Description

Technical Field

[0001] The utility model relates to a construction structure, in particular to a construction structure for tunnel collapse support and anti-deformation. Background Technique

[0002] Tunnel engineering is a common engineering form in modern transportation and urban construction, used to cross mountains, rivers or underground in cities, etc. However, during the tunnel construction process, risks such as rock formation collapse and structural deformation may be encountered, which pose serious challenges to construction safety and project quality. To solve these problems, traditional tunnel support structures have adopted simple methods, such as reinforcement of rock formations and simple lining structures. However, the traditional construction structure has the following defects:

[0003] Firstly, the anti-deformation ability is limited. When the traditional support structure faces large rock formation deformation pressure, it often cannot provide sufficient anti-deformation ability, resulting in structural failure and collapse. Secondly, the seismic performance is poor. Some traditional construction structures are easily damaged in natural disasters such as earthquakes and cannot provide sufficient safety protection. In addition, the inner wall of the traditional support is an integral decorative board surface, especially the top surface with a relatively high height. When minor deformation occurs, it is difficult to detect, so that when huge deformation occurs, people cannot escape in time. And when there is leakage and water seepage in the support, due to the random occurrence of water seepage, it is impossible to accurately locate the water seepage part when water seepage occurs, and the maintenance target is poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a construction structure for tunnel collapse support and anti-deformation to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A construction structure for tunnel collapse support and anti-deformation, including a rock formation matrix, the inner side wall of the rock formation matrix is provided with a first anchoring layer, the inner side wall of the first anchoring layer is fixedly provided with a first lining layer, the inner side wall of the first lining layer is fixedly provided with a second lining layer, the inner side wall of the second lining layer is provided with a second anchoring layer, the inner side wall of the second anchoring layer is fixedly provided with a smoothing layer, the inner side wall of the smoothing layer is fixedly provided with a waterproof layer, and the bottoms of the inner side walls on both sides of the waterproof layer are fixedly provided with a decorative board layer;

[0006] Between the top surfaces of the two decorative board layers, there are a plurality of spliced decorative boards. Inner grooves are opened on the spliced decorative boards, and a film package is fixedly connected between two opposite inner grooves. A colored solution is filled inside the film package. The bottoms of one side walls of the two decorative board layers are fixedly connected with collection boxes. One side wall of the collection box is fixedly connected with a thin plate. A plurality of partition plates are fixedly connected to the inner wall of the collection box at equal intervals. The interior of the collection box is divided into a plurality of cavities by the plurality of partition plates. Floating plates are arranged inside the plurality of cavities.

[0007] As a preferred technical solution of the present utility model, both the first anchoring layer and the second anchoring layer adopt prestressed anchor rods. The first anchoring layer penetrates into the rock formation matrix, and the second anchoring layer penetrates through the second lining layer and the first lining layer into the rock formation matrix.

[0008] As a preferred technical solution of the present utility model, the first anchoring layer and the second anchoring layer are arranged at intervals and crosswise.

[0009] As a preferred technical solution of the present utility model, the first lining layer is made of reinforced concrete, and the second lining layer is made of high-strength fiber-reinforced concrete.

[0010] As a preferred technical solution of the present utility model, the leveling layer adopts crack-resistant mortar, and the waterproof layer adopts waterproof coating.

[0011] As a preferred technical solution of the present utility model, the decorative board layer and the spliced decorative board are both fixedly bonded to the inner side wall of the waterproof layer by glue.

[0012] As a preferred technical solution of the present utility model, a plurality of label plates are fixedly connected to the front surface of the collection box. The plurality of label plates respectively correspond to a plurality of cavities, and the top surface of the floating plate is in a slope shape.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting the first lining layer and the second lining layer, the present utility model can reinforce the rock formation and share the ground pressure. The second lining layer made of high-strength fiber-reinforced concrete material has high crack resistance and deformation resistance, covers the surface of the first lining layer, and further increases the stability of the inner wall of the tunnel. By setting a plurality of first anchoring layers and second anchoring layers made of prestressed anchor rods, which are arranged crosswise at a certain interval inside the lining, and through the adjustment and transmission of the tensile force, the overall stability of the lining structure is increased, effectively resisting the deformation pressure of the rock formation, preventing the lining from being damaged and collapsing. At the same time, the waterproof layer and the decorative board layer of the lining can also protect the inside of the tunnel from water immersion and beautify the appearance of the tunnel.

[0015] 2. The utility model is provided with a plurality of spliced decorative plates. Once deformation and collapse occur, the large impact force caused by the integral dropping can be avoided. A film package is arranged between the inner grooves, and there is a colored solution inside. When slight dislocation deformation occurs, the leakage of the colored solution can be used to clearly prompt the personnel in the tunnel that the top spliced decorative plate has undergone deformation and dislocation, and emergency evacuation is required, so as to avoid the risk brought by the imperceptible deformation of the top surface of the traditional integral decorative plate. The provided collection box, floating plate and label plate can collect the leaked water at a fixed point. Subsequently, the maintenance personnel can judge the leakage position by observing the water collected in the cavity, and the maintenance target is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

The smoothing layer 6 uses anti-cracking mortar, and the waterproof layer 7 uses waterproof coating.

[0026] In specific use, the utility model provides a tunnel collapse support and anti-deformation construction structure. In actual tunnel support use, a multi-layer lining structure is introduced on the basis of the original single-layer lining structure, including a first lining layer 3 and a second lining layer 4, wherein the first lining layer 3 is located between a rock matrix 1 and the second lining layer 4, for reinforcing the rock layer and sharing ground pressure, the second lining layer 4 covers the surface of the first lining layer 3, for providing support and protection, the second lining layer adopts high-strength fiber reinforced concrete material to increase crack resistance and deformation resistance, prestressed anchor rods are arranged between the rock matrix 1 and the lining layer, these prestressed anchor rods are arranged in an intermittent and cross manner inside the lining, and the overall stability of the lining structure is increased by adjusting and transmitting the tension, the first anchoring layer 2 extends into the rock matrix 1 through the prestressed anchor rods to provide initial tension, the second anchoring layer 5 passes through the second lining 4 and the first lining layer 3 and extends into the rock matrix 1, for providing further tension, so that the lining structure is more tight and resistant to deformation pressure.

[0027] Embodiment 2:

[0028] On the basis of the first embodiment, Figure 1 and Figure 3 , Figure 4As shown, a plurality of spliced decorative boards 10 are provided between the top surfaces of two decorative board layers 8. Inner grooves 17 are formed in the spliced decorative boards 10. A film package 15 is fixedly connected between two opposite inner grooves 17. The film package 15 is made of rubber, corrosion-resistant, but will rupture under external pulling force. The inside of the film package 15 is filled with a colored solution 16. At the bottom of one side wall of each of the two decorative board layers 8, a collection box 9 is fixedly connected. A thin plate 14 is fixedly connected to one side wall of the collection box 9. A plurality of partition plates 11 are fixedly connected to the inner wall of the collection box 9 at equal intervals. The inside of the collection box 9 is divided into a plurality of cavities by the plurality of partition plates 11. A floating plate 12 is provided in each of the plurality of cavities. The decorative board layer 8 and the spliced decorative boards 10 are both fixedly bonded to the inner side wall of the waterproof layer 7 by glue. A plurality of label plates 13 are fixedly connected to the front surface of the collection box 9. The plurality of label plates 13 correspond to the plurality of cavities respectively. The top surface of the floating plate 12 is sloped. When water drops, it will flow along the slope into the inner bottom wall of the cavity. The floating plate 12 is made of a foam board and can float on the water surface, reducing evaporation. In this way, it does not affect the collection of water and greatly reduces evaporation. The timely seepage is very random and flexible, and part of the water can also be collected to clarify the leakage location.

[0029] During specific use, for a construction structure of a tunnel collapse support and anti-deformation of the present utility model, when rock formation deformation occurs, the deformation will act on a plurality of spliced decorative boards 10.

The film package 15 is made of rubber, and the colored solution 16 inside flows out. When the operator is in the tunnel, if it is observed that there is colored solution 16 seeping out between the spliced decorative boards 10 at the top, it indicates that displacement deformation has occurred here, and it is necessary to evacuate and deal with it in time. During daily support use, if the internal waterproof layer 7 leaks, water will seep on the decorative board layer 8. The seeping water will flow into the bottom collection box 9 along the slope. The water at the corresponding position will flow into the cavity at the corresponding position. The floating plate 12 covers the collected water surface, shielding the water surface and reducing evaporation. When the subsequent maintenance personnel patrol, by observing which corresponding cavity has water, the seepage area can be judged, and subsequent maintenance can be carried out at a fixed point.
