Description

Technical Field

[0001] This invention belongs to the field of retaining wall technology, specifically a reinforced gravity retaining wall earthquake-resistant structure. Background Technology

[0002] Reinforced gravity retaining walls, as an important structural form for slope protection and roadbed protection, directly affect the safety of engineering structures, the lives and property of personnel, and the stability of surrounding facilities due to their seismic performance. With the increasing demand for engineering construction in earthquake-prone areas and the continuous improvement of seismic design standards, the professionalism and reliability requirements for the seismic construction of reinforced gravity retaining walls are growing. Their structural design involves multiple aspects, including the coordinated stress distribution between the reinforcement materials and the wall body, the seismic stability of the foundation, and the overall deformation control of the structure. This places specific requirements on the seismic adaptability of the wall structure, the effectiveness of force transmission, and the coordination of deformation.

[0003] A Chinese invention patent with publication number CN118207902A discloses a seismic-resistant structure for a reinforced gravity retaining wall, relating to the technical field of retaining walls. The structure includes a seismic-resistant device comprising several movable parts, several first elastic parts, and several abutting parts; it also includes a driving device comprising several sliding parts and several linkage components. The sliding parts are slidably connected to the column. The movable parts can drive the abutting parts to contact and abut against the wall panel, and the direction of the force exerted by the abutting parts on the wall panel is the same as the direction of reinforcement of the wall panel by the bolts. At this time, the first elastic parts are compressed, and the first elastic parts have a tendency to drive the abutting parts away from the movable parts. This application can reduce the collision between the wall panel, column, and base plate caused by vibration, thereby reducing the wear of the wall panel, column, and base plate during vibration, and thus reducing the impact of vibration on the reinforced gravity retaining wall.

[0004] However, the above technologies often have the following drawbacks: the above foundation structures mostly adopt conventional gravity foundations or simple spread foundations, without targeted optimization for the dynamic response characteristics of the foundation soil under seismic action and the seismic connection nodes between the foundation and the superstructure, which can easily lead to problems such as foundation slippage, overturning or uneven settlement, and thus cause the overall seismic performance of the retaining wall to fail.

[0005] Therefore, the present invention provides a reinforced gravity retaining wall earthquake-resistant structure. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a reinforced gravity retaining wall seismic-resistant structure, including a first hinge plate, a shaft connection end on one side surface of the first hinge plate, a second hinge plate movably connected to the first hinge plate through the shaft connection end at the tail end, a similar shaft connection end on one side surface of the second hinge plate, the first hinge plate and the second hinge plate being connected end to end, a bottom partition panel being fixedly installed on the surfaces of both the first hinge plate and the second hinge plate by bolts, a through groove being provided on the surface of the bottom partition panel, a connecting surface being provided inside the through groove of the bottom partition panel, one side of the first hinge plate and the second hinge plate being respectively installed on the connecting surface, seismic-resistant components being fixedly installed at the four corners of one side surface of the bottom partition panel, a seismic isolation plate being fixedly installed on one end face of the seismic-resistant component, a recessed hole being opened on one end face of the seismic isolation plate, the seismic isolation plate and the bottom partition panel being placed parallel to each other, and a blocking plate being fixedly installed on the surface of the seismic isolation plate.

[0008] The baffle plate is provided with side ears at all four corners. The surface of the side ears is provided with threaded holes and is fixedly installed on the surface of the vibration isolation plate through bolt holes. The vibration isolation component includes a support cavity fixedly installed at the four corners of the bottom panel. The bottom of the outer arc surface of the support cavity is provided with a rubber bottom ring.

[0009] The outer arc surface of the support cavity is provided with an arc-shaped spring plate. The top of the arc-shaped spring plate has a through hole. The bottom side ear of the blocking plate passes through the vibration isolation plate and is fixedly connected to the bending area on the surface of the arc-shaped spring plate. The vibration isolation plate is disposed between the blocking plate and the arc-shaped spring plate.

[0010] The inner arc surface of the support cavity is provided with a partition section in the middle, and the bottom of the inner arc surface of the anti-seismic component is supported by an inner cylinder buffer, and the upper surface of the inner cylinder buffer is provided with an arched convex surface.

[0011] The upper surface of the dividing section is slidably overlapped with an inner cylinder movable column. The bottom of the lower surface of the inner cylinder movable column is provided with an extension end. The outer arc surface of the extension end is provided with an annular groove. The bottom surface of the extension end of the inner cylinder movable column is provided with a hook-shaped part.

[0012] The inner cylinder piston is connected to the arched convex surface through its extended end, and a limiting collar is movably engaged in the inner arc surface of the annular groove. Both the upper and lower end faces of the limiting collar are provided with ball heads.

[0013] The top ball head abuts against the surface of the dividing section, while the bottom ball head on the other side is movably engaged in the annular groove. A damping spring is fixedly installed on the upper surface of the inner cylinder piston.

[0014] A compression cap is fixedly installed at the top of the damping spring, and the upper surface of the compression cap extends through a through hole in the top surface of the arc-shaped spring plate. A vertical sensor is fixedly installed on one side surface of the arc-shaped spring plate by bolts.

[0015] The vertical sensor is placed at the bottom of the barrier plate. There are four supporting cavities, which are symmetrically placed at the four corners of the bottom surface of the barrier plate. An earthen wall is fixedly installed on one side of the barrier plate.

[0016] The beneficial effects of this invention are as follows: 1. Through a multi-level energy buffering mechanism consisting of an arc-shaped spring plate, damping springs, inner cylinder components, and a rubber bottom ring, seismic energy is absorbed and dissipated in layers, reducing the impact of vibration on the structure. Compared with traditional structures, this can effectively reduce the load transfer efficiency under seismic action, reduce structural stress concentration, improve the retaining wall's resistance to sliding and overturning in medium- to high-intensity earthquakes, and ensure the core safety of the structure.

[0017] 2. By adopting a flexible hinge design for the first and second hinge plates, it can flexibly adapt to the lateral and longitudinal deformations caused by earthquakes, effectively avoiding the cracking or breakage problems that are prone to occur in rigid connections. At the same time, the bottom panel firmly ensures the overall stability of the structure through the connection surface, achieving dynamic balance and improving the structural toughness and damage resistance of the retaining wall under complex vibration conditions.

[0018] 3. By using the ball head design of the limiting collar, sliding friction is converted into rolling friction, reducing wear on the inner cylinder piston and the supporting cavity. The pitted holes of the seismic isolation plate disperse the load and reduce local pressure. Combined with the buffer protection of the rubber bottom ring, the risk of rigid collision and erosion between components is reduced, fatigue damage is reduced, the service life of the entire seismic structure is extended, and the frequency of replacement is reduced.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3 As shown, this embodiment of the invention includes a first hinge plate 1. One side surface of the first hinge plate 1 is provided with a shaft connection end 101. The first hinge plate 1 is movably connected to a second hinge plate 2 through the shaft connection end 101 at its tail. One side surface of the second hinge plate 2 is provided with the same shaft connection end 101. The first hinge plate 1 and the second hinge plate 2 are connected end to end. The surfaces of the first hinge plate 1 and the second hinge plate 2 are both fixedly mounted with a bottom plate 3 by bolts. The surface of the bottom plate 3 is provided with a through groove. The inside of the through groove of the bottom plate 3 is provided with a connecting surface 301. One side of the first hinge plate 1 and the second hinge plate 2 are respectively mounted on the connecting surface 301. The four corners of one side surface of the bottom plate 3 are fixedly mounted with anti-vibration components 4. One end face of the anti-vibration component 4 is fixedly mounted with a vibration isolation plate 5. One end face of the vibration isolation plate 5 is provided with a recessed hole 501. The vibration isolation plate 5 and the bottom plate 3 are placed parallel to each other. A blocking plate 6 is fixedly mounted on the surface of the vibration isolation plate 5.

[0024] The earthen wall surface 8 is in direct contact with the slope soil. During an earthquake, it first bears the lateral pressure of the soil and the seismic inertial force, and evenly transfers the load to the inner retaining plate 6 to avoid localized stress concentration that could lead to structural damage. At the same time, as the main protective element of the retaining wall, it prevents soil slippage. The retaining plate 6, which is the force transmission and fixing carrier, bears the load transmitted by the earthen wall surface 8. Through the threaded holes on one side of its ear 601, bolts are used to firmly fix the retaining plate 5 and the arc-shaped elastic plate 411, ensuring connection stability. It disperses the concentrated load to the lower seismic isolation plate 5 and the seismic resisting component 4 to avoid excessive local stress.

[0025] The shock-absorbing and force-dispersing isolation plate 5 is located between the blocking plate 6 and the arc-shaped elastic plate 411. On the one hand, it initially absorbs vibration energy through the elastic deformation of its own plate. On the other hand, the pitted holes 501 on its surface can disperse the concentrated load transmitted to the plate surface, reduce local pressure, and enhance the deformation adaptability of the isolation plate 5. It avoids wear caused by rigid collision. The two hinged plates form a movable hinge structure through the shaft connection end 101 at the tail end. When the earthquake causes the retaining wall to deform laterally or longitudinally, the hinged plates can rotate relative to each other around the shaft connection end 101 to flexibly adapt to the structural deformation and prevent the risk of stress concentration caused by rigid connection. At the same time, the two hinged plates are connected end to end to ensure the continuity of the retaining structure.

[0026] The vertical sensor 7 for status monitoring and data feedback is fixedly installed on the surface of the arc-shaped elastic plate 411 and attached to the bottom of the blocking plate 6. It monitors the vertical displacement, vibration frequency and amplitude of the blocking plate 6 in real time during the earthquake and feeds the data back to the monitoring system, providing accurate data support for assessing the working status of the seismic structure, judging whether there is a risk of damage to the structure and subsequent maintenance.

[0027] like Figures 4 to 7 As shown, the baffle plate 6 has side ears 601 at each of its four corners. The surface of the side ears 601 has threaded holes and is fixedly installed on the surface of the vibration isolation plate 5 through bolt holes. The seismic stabilizing component 4 includes a support cavity 41 fixedly installed at the four corners of the bottom panel 3. The bottom of the outer arc surface of the support cavity 41 is provided with a rubber bottom ring 47. The top of the outer arc surface of the support cavity 41 is provided with an arc-shaped spring plate 411. The top of the arc-shaped spring plate 411 has a through hole. The side ears 601 on the bottom surface of the baffle plate 6 penetrate the vibration isolation plate 5 and are connected to the bending area of ​​the surface of the arc-shaped spring plate 411. The vibration isolation plate 5 is fixedly connected between the blocking plate 6 and the arc-shaped elastic plate 411. The inner arc surface of the support cavity 41 is provided with a partition section 412. The bottom of the inner arc surface of the anti-vibration component 4 is supported by an inner cylinder buffer 42. The upper surface of the inner cylinder buffer 42 is provided with an arched protrusion 421. The upper surface of the partition section 412 is slidably overlapped with an inner cylinder movable column 43. The bottom of the lower surface of the inner cylinder movable column 43 is provided with an extension end 431. The outer arc surface of the extension end 431 is provided with an annular groove 432. The bottom surface of the extension end 431 of the inner cylinder movable column 43 is provided with a hook-shaped part 433.

[0028] The inner cylinder piston column 43 overlaps the arched convex surface 421 via its extension end 431. A limiting collar 44 is movably engaged in the inner arc surface of the annular groove 432. Both the upper and lower end faces of the limiting collar 44 are provided with ball heads 441. The top ball head 441 abuts against the surface of the partition section 412, and the bottom ball head 441 on the other side is movably engaged in the annular groove 432. A damping shock absorber spring 45 is fixedly installed on the upper surface of the inner cylinder piston column 43. A compression cap 46 is fixedly installed on the top of the damping shock absorber spring 45. The upper surface of the compression cap 46 extends through the through hole on the top surface of the arc-shaped spring plate 411. A vertical sensor 7 is fixedly installed on one side surface of the arc-shaped spring plate 411 by bolts. The vertical sensor 7 is placed at the bottom of the baffle plate 6. There are four supporting cavities 41, which are symmetrically placed at the four corners of the bottom surface of the baffle plate 6. An earthen wall surface 8 is fixedly installed on one side of the baffle plate 6. When the seismic load or earth pressure is transmitted to the blocking plate 6, the force is transmitted through the side lug 601 to the arc-shaped elastic plate 411 and the seismic isolation plate 5, triggering the multi-level buffering and energy consumption mechanism of the seismic component 4. During the elastic deformation and spring damping stage, the arc-shaped elastic plate 411 undergoes elastic bending deformation under pressure, which simultaneously pushes the compression cover 46 downward to compress the damping spring 45. The damping spring 45 absorbs and consumes part of the seismic energy through its own elastic deformation, and then transmits the remaining pressure to the inner cylinder piston 43. The inner cylinder piston 43 moves downward along the support cavity 41 under pressure, and its extension end 431 overlaps the arched convex surface 421 of the inner cylinder buffer 42. Secondary buffering is achieved through the arc-shaped structure of the arched convex surface 421. At the same time, the limiting collar 44 in the annular groove 432 of the inner cylinder piston 43 abuts against the dividing section 412 and the annular groove 432 through the upper and lower ball heads 441, respectively, which not only restricts the movement range of the inner cylinder piston 43, but also reduces the friction loss between components through the rolling of the ball heads.

[0029] The rubber bottom ring 47 at the bottom of the bottom shock absorber and foundation is in contact with the foundation. The elasticity of the rubber is used to further absorb vibration energy, while preventing rigid collision between the support cavity 41 and the foundation due to vibration, thus avoiding the risk of foundation slippage.

[0030] Specific working principle: When vibration occurs, the soil pressure and vibration load on the earth wall surface 8 are first transmitted to the blocking plate 6. The energy buffer and dissipation of the seismic component 4 are achieved by the blocking plate 6 transmitting the force to the seismic isolation plate 5 and the arc-shaped elastic plate 411 through its side lugs 601. The arc-shaped elastic plate 411 undergoes elastic deformation under pressure, and at the same time pushes the compression cap 46 downward to compress the damping spring 45. The spring dissipates some of the seismic energy through elastic deformation. The pressure of the damping spring 45 is transmitted to the inner cylinder piston 43. The inner cylinder piston 43 moves downward along the support cavity 41, and its extension end 431 slides on the arched convex surface 421 of the inner cylinder buffer 42 to achieve secondary buffering.

[0031] The limiting collar 44 in the annular groove 432 of the inner cylinder piston 43 rotates flexibly between the partition section 412 and the annular groove 432 via the ball head 441, which not only limits the range of motion of the inner cylinder piston 43, but also reduces frictional loss between components. The rubber bottom ring 47 at the bottom of the support cavity 41 contacts the foundation, further absorbing vibration and preventing foundation slippage.

[0032] The first hinge plate 1 and the second hinge plate 2 are connected by a shaft connection end 101 to form a hinge connection. When the retaining wall deforms laterally or longitudinally due to an earthquake, the hinge plates can rotate relative to each other to adapt to the structural deformation and avoid stress concentration caused by rigid connection. At the same time, the bottom panel 3 provides installation support for the hinge plate through the connection surface 301 to ensure the integrity of the structure. The vertical sensor 7 installed on the arc-shaped elastic plate 411 monitors the vertical displacement and vibration status of the blocking plate 6 in real time, providing data support for the working status assessment and subsequent maintenance of the seismic structure.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
