Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, and in particular to a deformable earthquake-resistant device suitable for tunnel structures. Background Art

[0002] Tunnels refer to passages dug out of existing buildings or earth-rock structures for three-dimensional transportation, crossing mountains and ridges, underground passages, crossing rivers and seas, pipeline transportation, underground cables, water conservancy projects, etc. With the development of cities, more and more places are building tunnels. However, in earthquake zones, due to the frequent and strong earthquake activities in earthquake zones, in order to ensure that the traffic in the area is not easily blocked by earthquakes, the earthquake resistance of tunnels has become an inevitable problem.

[0003] At present, tunnel seismic resistance mainly weakens the earthquake effect by shock-absorbing rings, absorbs part of the energy of seismic waves, and attenuates the seismic energy consumption. The tunnel body is connected in sections, and flexible hinges are used at the section connections. The tunnel body adopts flexible links with the ability to withstand large deformations, so that the dislocation displacement is mainly absorbed by the flexible links, thereby improving the anti-seismic performance of the tunnel structure. However, the misalignment between adjacent tunnel components will directly lead to the rupture of some flexible components and their extrusion from the tunnel body. The existing flexible hinges between the dislocation displacements do not effectively absorb and dissipate the inertial force, axial force and other loads generated by the earthquake in both the vertical and horizontal directions. Once a small-scale depression occurs, it will directly collapse in linkage. The collapsed part of the depression cannot be supported by flexible deformation, and the collapsed part of the tunnel body will spread, making it impossible to safely and effectively support and fix the collapsed body.

[0017] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0018] 1. The tunnel support body and the tunnel base body are flexibly hinged vertically and horizontally through the first seismic component and the second seismic component on the connection block. In the lateral earthquake, the fixed sector plate and the first sector plate cross and are connected to the collapsed tunnel support body, expanding the connection area, greatly improving the stability performance of the tunnel support body.

[0019] 2.

An intersection will occur between the first sector plate and the fixed sector plate on the fixed rod, and the tunnel support body at the collapsed area will be hooked.

[0020] 3. The second rotating cylinder is enabled to rotate through the cooperation of the second rotating rod and the second rotating groove. The rack plate drives the arc plate to move in all directions through the movable holes, causing the triangular clamping blocks on the arc plate to abut against the inner wall of the tunnel support body, so that the collapsed area of the tunnel support body will not easily fall. The collapsed body will be internally supported and fixed by the arc plate in cooperation with the triangular clamping blocks, and the collapsed area will not directly fall or spread. The flexible connection stability of the collapsed area is completed through the cross-expanding arc plate.

[0021] 4. The honeycomb body can enhance the overall load-bearing capacity of the tunnel. Under the action of loads such as inertial force and axial force generated by an earthquake, it can better withstand these additional loads, prevent the tunnel from being structurally damaged or collapsed due to excessive stress, avoid excessive stress concentration in a certain part, reduce the internal force on the key parts of the structure, and improve the seismic performance of the structure. The shock-absorbing columns in the honeycomb body cooperate with the shock-absorbing holes to collapse layer by layer when compressed, dispersing the impact force in multiple directions, with a simple and ingenious design.

[0035] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0036] Embodiment: Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 、 Figure 11 and Figure 12As shown in the figure, it includes a tunnel support body 10. The tunnel is composed of multiple tunnel support bodies 10 and tunnel base bodies 11 at both ends. A number of connection slots 12 are provided between the tunnel support body 10 and the tunnel base body 11. Installation slots 13 are provided on both sides of the connection slot 12 of the tunnel support body 10. A connection block 14 for connecting the tunnel support body 10 is arranged in the connection slot 12. The connection block 14 is provided with a first anti-seismic component in the transverse direction of the tunnel, and the connection block 14 is provided with a second anti-seismic component in the longitudinal direction of the tunnel.

[0037] The first anti-seismic component includes a fixed rod 20 and a first rotating cylinder 21. A honeycomb body 30 is arranged inside the connection block 14. The honeycomb body 30 is welded and connected with a fixed rod 20 that moves outside the connection block 14 through a first spring 22. The connection block 14 is movably connected with the first rotating cylinder 21 through a bearing on the outer periphery of the fixed rod 20. The fixed rod 20 is fixedly installed with a first rotating rod 23 that drives the first rotating cylinder 21 to rotate. The first rotating rod 23 and the first rotating cylinder 21 complete an interleaving movement during the anti-seismic process. A buffer component is arranged between the fixed rod 20 and the honeycomb body 30, and the buffer component is used to enable the tunnel support body 10 connected by the fixed rod 20 to achieve the effect of anti-seismic stretching.

[0038] The second anti-seismic component includes a fixed disk 50, a second rotating cylinder 61 and a support rod 60. The honeycomb body 30 is connected with the support rod 60 through a second spring 62. The connection block 14 is connected with the fixed disk 50 through an L-shaped mounting rod 51. The outer periphery of the support rod 60 is movably provided with the second rotating cylinder 61. The periphery of the fixed disk 50 is connected with an arc-shaped plate 70 through a rack plate 71. The second rotating cylinder 61 drives the arc-shaped plate 70 to expand around the fixed disk 50 through a second rotating rod 63 and a second rotating groove 64. After the arc-shaped plate 70 expands, the collapsed part of the tunnel support body 10 is internally supported and connected, and the collapsed body will not directly fall from the tunnel.

[0039] Refer to Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In addition, a shock absorption component is arranged inside the honeycomb body 30. The shock absorption component includes a shock absorption column 31 with a regular hexagon structure. A shock absorption hole 32 is opened at the center of the shock absorption column 31, and the shock absorption hole 32 can also be filled with a rubber body to assist the honeycomb body 30 in anti-seismic. The honeycomb body 30 is spliced by a plurality of shock absorption columns 31. Triangular blocks 33 are welded and fixedly installed at both ends of the honeycomb body 30 located at the fixed rod 20. The first spring 22 is welded and fixed on the triangular blocks 33. The stress stretching of the fixed rod 20 is completed through the cooperation of the first spring 22 and the honeycomb body 30.

[0040] The buffer assembly includes a first pillar 40, a second pillar 41, a third spring 42 and a fourth spring 43. The triangular block 33 is movably provided with a buffer plate 44 on the top of the first spring 22. The top of the fixed rod 20 is movably connected to the first pillar 40 through a hinge seat 45. The top of the first pillar 40 is movably provided with a second pillar 41. The top of the second pillar 41 is installed on the top of the buffer plate 44 through the hinge seat 45. The third spring 42 is installed at the bottom of the first pillar 40. The top of the third spring 42 is installed at the bottom of the second pillar 41, and the bottom of the second pillar 41 is movable at the top of the first pillar 40. The stress stretching between the fixed rod 20 and the honeycomb body 30 is assisted by the first pillar 40, the third spring 42 and the second pillar 41, so that the fixed rod 20 is stable during the anti-seismic stretching process.

[0041] The triangular block 33 is provided with a buffer groove 34, and fourth springs 43 are welded and fixed to the triangular block 33 at both ends of the buffer groove 34. A buffer block 35 movable in the buffer groove 34 is fixedly installed between the fourth springs 43, and the top of the buffer block 35 is fixedly installed on the buffer plate 44 by bolts. The fourth spring 43 cooperates with the buffer block 35 to flexibly stretch the buffer plate 44 in the buffer groove 34, and the lateral tensile force is transferred to the vertical tensile force, so that the fixed rod 20 achieves a stable buffering effect during the stretching process.

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 and Figure 9 A first rotating groove 24 that matches the size of the first rotating rod 23 is opened inside the first rotating cylinder 21, and the first rotating rod 23 moves in the first rotating groove 24. A first fan-shaped plate 25 is welded and fixed to the end of the first rotating cylinder 21 away from the first spring 22, and a fixed fan-shaped plate 26 is welded and fixed to the end of the fixed rod 20 away from the first spring 22, and the first fan-shaped plate 25 and the fixed fan-shaped plate 26 are in a horizontal state. When an earthquake occurs, the first fan-shaped plate 25 and the fixed fan-shaped plate 26 form an angle due to the rotation of the first rotating cylinder 21. The first fan-shaped plate 25 and the fixed fan-shaped plate 26 expand the contact area of ​​the collapsed tunnel support body 10, and the collapsed body is fixedly supported by the first fan-shaped plate 25 and the fixed fan-shaped plate 26, so as to effectively prevent the collapsed body from spreading to the surroundings.

[0043] The tunnel support body 10 is fixedly installed with an installation block 15 in the installation groove 13. An arc-shaped seismic plate 16 is fixedly welded between the installation block 15 and the connection block 14. Deformation grooves 17 are formed around the connection block 14 of the tunnel support body 10 and the tunnel base body 11. The first rotating cylinder 21 and the second rotating cylinder 61 are movably arranged in the deformation grooves 17. The arc-shaped seismic plate 16 resists earthquakes by using its own structure, and absorbs and dissipates the deformation energy transmitted by the earthquake through the change of its own shape, thereby reducing the damage effect of the earthquake on the tunnel structure.

[0044] Refer to Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 , on one side of the second spring 62, the fixed disk 50 is provided with an annular groove 52. A T-shaped slider 53 is slidably connected in the annular groove 52 of the fixed disk 50. The top end of the T-shaped slider 53 is fixedly installed with a rotating gear ring 65 through a bolt. The rotating gear ring 65 is fixedly installed with the second rotating cylinder 61 through a bolt. Inside the second rotating cylinder 61, a second rotating rod 63 is fixedly welded to the support rod 60. A second rotating groove 64 is formed on the inner side of the second rotating cylinder 61, and the second rotating rod 63 is movably arranged in the second rotating groove 64. The stress stretching movement of the support rod 60 drives the second rotating rod 63 to move synchronously. The second rotating rod 63 rotates the second rotating cylinder 61 on the fixed disk 50 through the second rotating groove 64.

[0045] Four groups of support rotating shafts 54 are movably connected to the inside of the fixed disk 50 through bearings. A connecting gear 55 is fixedly installed on the outer periphery of the support rotating shaft 54. The connecting gear 55 is movably meshed with the rack plate 71. The top of the support rod 60 penetrates and extends to the outside of the fixed disk 50. At the end of the support rod 60 away from the second spring 62, a second sector plate 66 is fixedly welded. The second sector plate 66 increases the area in contact with the collapsed area, making the stress stretching of the collapsed area on the support rod 60 stable. The rotating gear ring 65, the support rotating shaft 54, and the connecting gear 55 cooperate with the limit base 56 to perform a synchronous expansion movement on the rack plate 71.

[0046] Refer to Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 10 and Figure 12 , inside the fixed disk 50, a limit base 56 is fixedly installed through a bolt. A limit sliding groove 57 is formed at the top of the limit base 56. A limit sliding block 58 is slidably connected in the limit sliding groove 57 of the limit base 56. The top end of the limit sliding block 58 is fixedly installed on the rack plate 71, making the rack plate 71 perform a stable diffusion movement along the limit base 56.

[0047] The fixed disk 50 is provided with movable holes 59 around it that match the size of the rack plate 71. The rack plates 71 all pass through the movable holes 59 movably. On the side of the arc plate 70 away from the rack plate 71, a triangular clamping block 72 is fixedly installed. The expanded arc plate 70 cooperates with the triangular clamping block 72 to fix the inner side of the tunnel support 10 around the deformation groove 17, effectively preventing the tunnel support 10 from breaking and falling under the influence of longitudinal waves, thereby expanding the collapse area.

[0048] Working principle: The tunnel is supported and assembled by multiple tunnel supports 10 and two groups of tunnel base bodies 11. The installation block 15 is filled into the installation groove 13, and then the connection block 14 is placed into the tunnel support 10 and the tunnel base body 11. The arc-shaped seismic plate 16 is used to connect between the installation block 15 and the connection groove 12. When an earthquake occurs in the tunnel, when the horizontally generated seismic waves reach between the tunnel supports 10, once the adjacent tunnel supports 10 collapse and sink, the fixed sector plate 26 will drive the fixed rod 20 to be buffer-pulled. The first spring 22 will be stretched for earthquake resistance. The first strut 40 and the second strut 41 between the fixed rod 20 and the honeycomb body 30 cooperate with the third spring 42 to achieve the earthquake resistance energy storage effect. At the same time, the fourth spring 43 on the triangular block 33 cooperates with the buffer block 35 to assist the fixed rod 20 to complete the resistance stretching. During the stretching process of the fixed rod 20, the first rotating rod 23 on the fixed rod 20 will drive the first rotating cylinder 21 to rotate through the first rotating groove 24, causing the first sector plate 25 on the first rotating cylinder 21 to perform a vertical rotation movement, so that an intersection occurs between the first sector plate 25 and the fixed sector plate 26 on the fixed rod 20. In this way, the tunnel supports 10 at the collapse site will be hooked, preventing the tunnel supports 10 at the collapse site from separating due to vibration. The fixed sector plate 26 and the first sector plate 25 cross and connect with the collapsed tunnel supports 10, expanding the connection area and greatly improving the stability performance of the tunnel supports 10;

[0049] When the longitudinal seismic wave longitudinally stretches and expands the tunnel support 10, similarly, the collapsed area pulls the support rod 60 to move through the second sector plate 66. The support rod 60 will also achieve buffer stretching through the second spring 62. At the same time, when the support rod 60 is in the stretching movement, it will drive the second rotating cylinder 61 to complete the rotating movement through the cooperation of the second rotating rod 63 and the second rotating groove 64. At this time, the second rotating cylinder 61 drives the rotating tooth ring 65 on the fixed disk 50 to rotate synchronously. The rotating tooth ring 65 makes a stable rotating movement under the action of the annular groove 52 and the T-shaped slider 53. The rotating tooth ring 65 meshes to drive the connecting gear 55 on the support rotating shaft 54 to rotate. The connecting gear 55 meshes to drive the rack plate 71 on the limit base 56 to move diffusely. The rack plate 71 drives the arc plate 70 to move around through the movable hole 59, so that the triangular clamping block 72 on the arc plate 70 abuts against the inner wall of the tunnel support 10, so that the collapsed area of the tunnel support 10 will not easily fall. The collapsed body will be internally supported and fixed by the arc plate 70 and the triangular clamping block 72. The arc plate 70 expands the connection area of the collapsed body, increases the friction force, and prevents the collapsed body from detaching;

[0050] When the fixed rod 20 and the support rod 60 resist and stretch the longitudinal and transverse seismic waves, the honeycomb body 30 connected by the first spring 22 and the second spring 62 can enhance the overall bearing capacity of the tunnel. Under the action of loads such as inertial force and axial force generated by the earthquake, it can better bear these additional loads, avoid structural damage or collapse of the tunnel due to excessive force, avoid excessive stress concentration in a certain part, reduce the internal force on the key parts of the structure, and improve the seismic performance of the structure. The shock-absorbing columns 31 in the honeycomb body 30 cooperate with the shock-absorbing holes 32 to collapse layer by layer when compressed, and disperse the impact force in multiple directions.

[0051] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art.
