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.

[0023] Embodiment: Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 , Fig.11 and Fig.12 As shown, a tunnel support body 10 is included. The tunnel is composed of a plurality of tunnel support bodies 10 and tunnel base bodies 11 at both ends.

The connecting block 14 is provided with a first anti-seismic component in the transverse direction of the tunnel, and the connecting block 14 is provided with a second anti-seismic component in the longitudinal direction of the tunnel. The first seismic-resistant component includes a fixed rod 20 and a first rotating cylinder 21. A honeycomb body 30 is arranged in the connecting block 14. The honeycomb body 30 is welded and connected to the fixed rod 20 movable on the outside of the connecting block 14 through a first spring 22. The connecting block 14 is movably connected to the first rotating cylinder 21 on the outer periphery of the fixed rod 20 through a bearing. 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 interlaced movement during the seismic resistance process. A buffer component is arranged between the fixed rod 20 and the honeycomb body 30. The buffer component is used to enable the tunnel support body 10 connected to the fixed rod 20 to achieve a seismic-resistant stretching effect.

[0024] The second seismic resistant component includes a fixed plate 50, a second rotating cylinder 61 and a support rod 60. The honeycomb body 30 is connected to the support rod 60 through a second spring 62. The connecting block 14 is connected to the fixed plate 50 through an L-shaped mounting rod 51. The second rotating cylinder 61 is movably arranged on the periphery of the support rod 60. The fixed plate 50 is connected to an arc plate 70 around the four sides through a rack plate 71. The second rotating cylinder 61 drives the arc plate 70 to expand and move around the fixed plate 50 through the second rotating rod 63 and the second rotating groove 64. After the arc plate 70 expands and moves, the collapsed part of the tunnel support body 10 is connected by the inner support, and the collapsed body will not fall directly from the tunnel.

[0025] See also Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 A shock absorbing assembly is arranged in the honeycomb body 30, and the shock absorbing assembly includes a shock absorbing column 31 with a regular hexagonal structure. A shock absorbing hole 32 is opened at the center of the shock absorbing column 31, and the shock absorbing hole 32 can also be filled with a rubber body to assist the honeycomb body 30 in earthquake resistance. The honeycomb body 30 is spliced ​​by a plurality of shock absorbing columns 31. The honeycomb body 30 is welded and fixed with triangular blocks 33 at both ends of the fixing rod 20. The first spring 22 is welded and fixed on the triangular block 33. The stress stretching of the fixing rod 20 is completed by the first spring 22 cooperating with the honeycomb body 30.

[0026] 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.

[0027] 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.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 and Fig. 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.

[0029] The tunnel support body 10 is fixedly installed with a mounting block 15 in the mounting groove 13, and an arc-shaped seismic-resistant plate 16 is welded and fixed between the mounting block 15 and the connecting block 14. The tunnel support body 10 and the tunnel base body 11 are provided with deformation grooves 17 around the connecting block 14. The first rotating cylinder 21 and the second rotating cylinder 61 move in the deformation groove 17. The arc-shaped seismic-resistant plate 16 uses its own structure to resist earthquakes, and absorbs and dissipates the deformation energy transmitted by the earthquake by changing its own shape, thereby reducing the destructive effect of the earthquake on the tunnel structure.

[0030] See also Figure 5 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 The fixed plate 50 is provided with an annular groove 52 on one side of the second spring 62, and the fixed plate 50 is slidably connected with a T-shaped slider 53 in the annular groove 52. A rotating gear ring 65 is fixedly installed on the top of the T-shaped slider 53 by bolts, and a second rotating cylinder 61 is fixedly installed on the rotating gear ring 65 by bolts. The support rod 60 is welded and fixed with a second rotating rod 63 inside the second rotating cylinder 61. A second rotating groove 64 is provided on the inner side of the second rotating cylinder 61, and the second rotating rod 63 moves in the second rotating groove 64. The stress stretching movement of the support rod 60 drives the second rotating rod 63 to move synchronously, and the second rotating rod 63 rotates the second rotating cylinder 61 on the fixed plate 50 through the second rotating groove 64.

[0031] Four groups of supporting shafts 54 are movably connected through bearings in the fixed plate 50, and a connecting gear 55 is fixedly installed on the outer periphery of the supporting shaft 54. The connecting gear 55 is movably engaged with the rack plate 71. The top of the support rod 60 extends through the outside of the fixed plate 50, and the support rod 60 is welded and fixedly installed with a second fan-shaped plate 66 at the end away from the second spring 62. The second fan-shaped plate 66 increases the area of ​​the collapsed part, so that the stress stretching of the support rod 60 at the collapsed part is stable. The rack plate 71 is synchronously expanded by rotating the gear ring 65, the supporting shaft 54, the connecting gear 55 and the limiting base 56.

[0032] See also Figure 2 , Figure 5 , Figure 6 , Figure 8 , Fig.10 and Fig.12 A limiting base 56 is fixedly installed inside the fixed plate 50 by bolts, and a limiting slide groove 57 is provided on the top of the limiting base 56. The limiting base 56 is slidably connected to a limiting slider 58 in the limiting slide groove 57. The top of the limiting slider 58 is fixedly installed on the rack plate 71, so that the rack plate 71 undergoes a stable diffusion movement along the limiting base 56.

[0033] Movable holes 59 of the same size as the rack plate 71 are provided around the fixed plate 50, and the rack plate 71 is movable through the movable holes 59. A triangular clamping block 72 is fixedly installed on the side of the arc plate 70 away from the rack plate 71. The expanded arc plate 70 cooperates with the triangular clamping block 72 to fix the tunnel support body 10 inside around the deformation groove 17, effectively preventing the tunnel support body 10 from breaking and falling under the influence of longitudinal waves, thereby expanding the collapse area.

[0034] Working principle: The tunnel is supported and assembled by multiple tunnel support bodies 10 and two groups of tunnel base bodies 11. The installation block 15 is filled into the installation groove 13, and then the connecting block 14 is placed into the tunnel support body 10 and the tunnel base body 11. The arc-shaped earthquake-resistant plate 16 is used to connect the installation block 15 and the connecting groove 12. When an earthquake occurs in the tunnel, when the transverse seismic waves reach between the tunnel support bodies 10, once the adjacent tunnel support bodies 10 collapse and the depressions are located, the fixed sector plate 26 will drive the fixed rod 20 to buffer and pull, and the first spring 22 will be seismically stretched. The first pillar 40 and the second pillar 41 between the fixed rod 20 and the honeycomb body 30 cooperate with the third spring 42 to achieve an earthquake-resistant force storage effect. When 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, and during the stretching process of the fixed rod 20, the first rotating rod 23 on the fixed rod 20 will drive the first rotating drum 21 to rotate through the first rotating groove 24, so that the first fan-shaped plate 25 on the first rotating drum 21 will rotate vertically, so that the first fan-shaped plate 25 and the fixed fan-shaped plate 26 on the fixed rod 20 are staggered, so that the tunnel support body 10 at the collapsed position will be hooked to prevent the tunnel support body 10 at the collapsed position from being separated due to vibration. The fixed fan-shaped plate 26 and the first fan-shaped plate 25 are cross-connected with the collapsed tunnel support body 10, thereby expanding the connection area and greatly improving the stability of the tunnel support body 10. When the longitudinal seismic wave longitudinally stretches and expands the tunnel support body 10, the collapsed part pulls the support rod 60 to move through the second fan-shaped plate 66, and the support rod 60 will also achieve buffering stretching through the second spring 62. At the same time, when the support rod 60 is stretched, the second rotating rod 63 cooperates with the second rotating groove 64 to make the second rotating drum 61 also complete the rotation movement. At this time, the second rotating drum 61 drives the rotating gear ring 65 on the fixed plate 50 to rotate synchronously. The rotating gear ring 65 rotates stably under the action of the annular groove 52 and the T-shaped slider 53. The meshing drives the connecting gear 55 on the supporting shaft 54 ​​to rotate, and the meshing drives the rack plate 71 on the limiting base 56 to diffuse, and the rack plate 71 drives the arc plate 70 to move in all directions 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 body 10, so that the collapsed part of the tunnel support body 10 will not fall easily, and the collapsed body will be supported and fixed by the arc plate 70 in cooperation with the triangular clamping block 72, and the arc plate 70 will expand the connection area of ​​the collapsed body, increase the friction force, and prevent the collapsed body from falling off; When the fixing rod 20 and the supporting rod 60 resist 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 the inertial force, axial force and other loads generated by the earthquake, it can better withstand these additional loads, avoid structural damage or collapse of the tunnel due to excessive force, avoid excessive concentration of stress in a certain part, reduce the internal force of 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 under pressure, and disperse the impact force to multiple directions.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
