Description

Technical Field

[0001] This utility model relates to the field of tunnel lining energy dissipation and vibration reduction technology, specifically to a tunnel lining energy dissipation and vibration reduction structure suitable for seismic zones. Background Technology

[0002] Tunnel lining refers to a permanent support structure constructed with reinforced concrete and other materials around the tunnel body to prevent deformation or collapse of the surrounding rock. Its main functions include reinforcement and support, optimization of the route drainage system, beautification of appearance, and facilitating the installation of communication, lighting, monitoring and other facilities to meet the requirements of modern highway tunnel construction. In earthquake-prone areas, tunnel lining needs to be energy-dissipating and vibration-damping in order to ensure its service life and safety.

[0003] Currently, the energy dissipation and vibration reduction structure for tunnel linings generally involves filling the space between the tunnel lining and the support plate with flexible material. The elasticity of the flexible material achieves vibration reduction in the tunnel lining. However, this method has a short service life, and the flexible material is easily damaged, affecting its energy dissipation effect. Furthermore, filling the space between the tunnel lining and the support plate with vibration-damping material can also reduce the connection strength between the lining and the support plate. Therefore, we propose an energy dissipation and vibration reduction structure for tunnel linings in seismic zones to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an energy dissipation and vibration reduction structure for tunnel linings in earthquake zones, in order to solve the problems mentioned in the background art, such as the low energy dissipation and vibration reduction effect of tunnel linings on the market and the impact on the robustness of tunnel linings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tunnel lining energy dissipation and vibration reduction structure suitable for seismic zones, comprising a tunnel lining layer, a first tunnel support plate disposed on the outer side of the tunnel lining layer, a second tunnel support plate disposed on the outer side of the first tunnel support plate, an energy dissipation component installed between the first tunnel support plate and the second tunnel support plate, an internal damper hinged to the side of the first tunnel support plate away from the tunnel lining layer, and the end of the internal damper away from the first tunnel support plate hinged to the second tunnel support plate;

[0006] The first tunnel support plate is provided with a reinforcement component for improving the connection strength of the tunnel lining layer. A top plate is installed on the top of the side of the tunnel lining layer away from the first tunnel support plate. A first external damper and a second external damper are hinged below the top plate. The lower ends of the first external damper and the second external damper are both hinged to the inner wall of the tunnel lining layer.

[0007] Preferably, the reinforcement component includes a connecting column connected to the sidewall of the first tunnel support plate, the end of the connecting column away from the first tunnel support plate being connected to a connecting seat, and the end of the connecting seat away from the connecting column being connected to a rubber seat.

[0008] Preferably, the energy dissipation component includes a first structural frame column, a flexible connecting plate, and a second structural frame column. The first and second structural frame columns are respectively connected to the second tunnel support plate and the first tunnel support plate, and a flexible connecting plate connects the first and second structural frame columns.

[0009] Preferably, the connecting column, connecting seat, and rubber seat are all hollow, and the connecting column penetrates the side wall of the first tunnel support plate.

[0010] Preferably, the energy dissipation components are distributed between the two sets of internal dampers, and the positions of the energy dissipation components and internal dampers are staggered from the positions of the connecting columns.

[0011] Preferably, the first external damper and the second external damper are staggered and distributed at equal intervals on the first tunnel support plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This structure is applicable to tunnel lining energy dissipation and vibration reduction in seismic zones. It uses an internal damper, a first external damper, a second external damper, and energy dissipation components to dissipate energy and reduce vibration on different sides of the tunnel lining. While dissipating energy and reducing vibration on the tunnel lining layer, it can distribute the residual force to various locations of the tunnel lining layer, avoiding the residual force from being concentrated in a certain place of the tunnel lining layer and causing damage to the tunnel lining layer.

[0014] (2) This structure is applicable to tunnel lining energy dissipation and vibration reduction in seismic zones. When the tunnel lining layer is poured, the concrete is simultaneously attached to the second tunnel support plate along the hollow connecting column, connecting seat and rubber seat to form a concrete column that connects the second tunnel support plate and the tunnel lining layer, thereby improving the connection strength of the tunnel lining.

[0021] 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 protection scope of the present utility model.

[0022] Please see Figures 1-5 The present invention provides the following technical solution: a tunnel lining energy dissipation and vibration reduction structure suitable for earthquake zones, comprising a tunnel lining layer 1, a first tunnel support plate 2 provided on the outside of the tunnel lining layer 1, a second tunnel support plate 6 provided on the outside of the first tunnel support plate 2, an energy dissipation component 8 installed between the first tunnel support plate 2 and the second tunnel support plate 6, an internal damper 7 hinged to the side of the first tunnel support plate 2 away from the tunnel lining layer 1, and the end of the internal damper 7 away from the first tunnel support plate 2 hinged to the second tunnel support plate 6.

[0023] Furthermore, the energy dissipation component 8 includes a first structural frame column 801, a flexible connecting plate 802, and a second structural frame column 803. The first structural frame column 801 and the second structural frame column 803 are respectively connected to the second tunnel support plate 6 and the first tunnel support plate 2, and the flexible connecting plate 802 is connected between the first structural frame column 801 and the second structural frame column 803.

[0024] The energy dissipation component 8 is distributed between the two sets of internal dampers 7. The positions of the energy dissipation component 8 and the internal dampers 7 are staggered from the positions of the connecting column 3, so that the internal dampers 7 work with the energy dissipation component 8 to reduce vibration and dissipate energy in the tunnel lining.

[0025] The first tunnel support plate 2 is provided with a reinforcement component for improving the connection strength of the tunnel lining layer 1. A top plate 9 is installed on the top of the side of the tunnel lining layer 1 away from the first tunnel support plate 2. A first external damper 10 and a second external damper 11 are hinged below the top plate 9. The lower ends of the first external damper 10 and the second external damper 11 are both hinged to the inner wall of the tunnel lining layer 1.

[0026] Furthermore, the reinforcement component includes a connecting column 3 connected to the side wall of the first tunnel support plate 2, a connecting seat 4 connected to the end of the connecting column 3 away from the first tunnel support plate 2, and a rubber seat 5 connected to the end of the connecting seat 4 away from the connecting column 3.

[0027] Furthermore, the connecting column 3, connecting seat 4, and rubber seat 5 are all hollow. The connecting column 3 penetrates the side wall of the first tunnel support plate 2. When the tunnel lining layer 1 is poured, the concrete connects to the second tunnel support plate 6 along the connecting column 3, connecting seat 4, and rubber seat 5, and the poured concrete column reinforces the tunnel lining layer 1.

[0028] Furthermore, the first external damper 10 and the second external damper 11 are staggered and distributed at equal intervals on the first tunnel support plate 2. The first external damper 10 and the second external damper 11 are used to dissipate energy and reduce vibration on the tunnel lining from the other side, and the remaining force can be distributed on the tunnel lining to reduce damage to the tunnel lining.

[0029] Specifically, the second tunnel support plate 6 is installed into the tunnel using anchor bolts, followed by the installation of the first tunnel support plate 2. An internal damper 7 is hinged between the first tunnel support plate 2 and the second tunnel support plate 6, and an energy dissipation component 8 is connected. During the assembly of the first tunnel support plate 2, the rubber seat 5 rests against the inner wall of the second tunnel support plate 6. Due to the compressive force between the first tunnel support plate 2 and the second tunnel support plate 6, the rubber seat 5 deforms under stress, adapting to the shape of the inner wall of the second tunnel support plate 6 and the second tunnel support plate 6. The plates 6 are tightly fitted together, so that the second tunnel support plate 6 and the connecting seat 4 are sealed and fitted together. Then the tunnel lining layer 1 can be poured. The poured concrete can also be fitted to the second tunnel support plate 6 along the hollow connecting column 3, connecting seat 4 and rubber seat 5. When the tunnel lining layer 1 is poured and formed, the concrete in the connecting column 3, connecting seat 4 and rubber seat 5 is also formed, connecting the second tunnel support plate 6 and the tunnel lining layer 1, and making a shock absorption and energy dissipation layer between the tunnel lining layer 1 and the second tunnel support plate 6.

[0030] During an earthquake, the internal damper 7, the first external damper 10, and the second external damper 11 are used for vibration reduction and energy dissipation. At the same time, the flexible connecting plate 802 between the first structural frame column 801 and the second structural frame column 803 also assists in vibration reduction and energy dissipation. The internal damper 7, the first external damper 10, the second external damper 11, and the energy dissipation component 8 are evenly distributed, which can disperse the force to various positions of the tunnel lining layer 1 while dissipating energy and reducing vibration. This disperses the force on the tunnel lining layer 1, reduces the damage to the tunnel lining layer 1, and strengthens the energy dissipation and vibration reduction of the tunnel lining layer 1. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
