[0002] Reinforced earth retaining wall refers to a composite structure consisting of fill, a certain amount of strip reinforcement arranged in the fill, and upright wall panels. This structure has interacting internal forces such as wall surface soil pressure, reinforcement tension, and friction between fill and reinforcement. These forces are balanced to ensure the stability of the composite structure. Reinforced earth retaining walls are widely used in transportation, water conservancy, construction and other fields.

[0003] However, when traditional reinforced earth retaining walls are installed, the wall panels and the reinforcement are generally connected by welding, bolting or bayonet connection. This connection method makes the connection point between the wall panel and the reinforcement fixed. When an earthquake occurs, the impact force generated by the earthquake will directly act on this connection point, thereby destroying the connection point, causing the wall panel to fall off and the reinforcement to be pulled out, thereby reducing the stability and safety of the reinforced earth retaining wall.

DETAILED DESCRIPTION

[0031] See also Figure 1 to Figure 7 In an embodiment of the present invention, a reinforced earth retaining wall with shock absorption and energy dissipation includes an assembly panel 1, ribs 2 and an energy dissipation connection component 3, wherein the energy dissipation connection component 3 is fixedly arranged on the assembly panel 1 by bolts, and the other end of the energy dissipation connection component 3 is fixedly connected to the ribs 2;

[0032] The energy dissipation connection assembly 3 includes a fixed seat 31, an energy dissipation block 32 and a deflection block 33, wherein the fixed seat 31 is fixedly connected to the assembly panel 1, a sliding cavity 311 is provided in the fixed seat 31, the energy dissipation block 32 is slidably arranged in the sliding cavity 311, and a gap exists between the energy dissipation block 32 and the sliding cavity 311, a spherical deflection groove 321 is provided in the energy dissipation block 32, the deflection block 33 is rotatably arranged in the deflection groove 321, a connecting rod 331 is fixedly connected to the deflection block 33 by a thread, the connecting rod 331 is fixedly connected to the rib 2, the fixed seat 31 and the energy dissipation block 32 are both provided with a through hole for the connecting rod 331 to pass through, and there is a gap between the connecting rod 331 and the two through holes;

[0033] A gap is provided between the connecting rod 331 and the two through holes, so that when the deflection block 33 rotates, the connecting rod 331 has a deflection space, thereby preventing the connecting rod 331 from hitting the fixing seat 31 or the energy dissipation block 32 and causing damage to the components;

[0034] The deflection block 33 includes a rotating block 332 and a shock absorbing plate 333, wherein the rotating block 332 is spherical and has the same size as the deflection slot 321, the rotating block 332 is rotatably arranged along the deflection slot 321, and the shock absorbing plate 333 is fixedly arranged on the rotating block 332;

[0035] The damping plate 333 is an annular plate and its center coincides with the center of the rotating block 332 . A spherical annular plate 334 is fixedly disposed on the damping plate 333 .

[0036] The energy dissipation block 32 is provided with a T-shaped shock absorbing groove 322, the inner side surface of the shock absorbing groove 322 is a spherical surface, the ring plate 334 fits the inner side surface of the shock absorbing groove 322 and rotates along the shock absorbing groove 322, and a plurality of shock absorbing springs 335 are evenly arranged on both sides of the ring plate 334 in a circumferential manner, and the other end of the shock absorbing spring 335 is fixedly connected to the shock absorbing groove 322;

[0037] It should be noted that the inner side of the shock absorbing groove 322 and the ring plate 334 are set to be spherical, and the center of the shock absorbing plate 333 (i.e., the ring plate 334) is set to coincide with the center of the rotating block 332, so that when the rotating block 332 deflects at multiple angles along the deflection groove 321, the ring plate 334 can also deflect at multiple angles along the shock absorbing groove 322, and can squeeze the shock absorbing spring 1 335 during the deflection process, so that the deflection block 33 can offset the radial force at various angles, that is, ensure that the tensile force generated by the earthquake is absorbed and eliminated;

[0038] A plurality of sliding holes 312 are provided on one side of the fixing seat 31 close to the energy dissipation block 32, a sliding plate 313 is slidably arranged in the sliding hole 312, and a second shock absorbing spring 314 is fixedly arranged between the sliding plate 313 and the sliding hole 312;

[0039] A plurality of guide blocks 323 are fixedly disposed on one side of the energy dissipation block 32 close to the fixed seat 31. The guide blocks 323 are slidably connected with the sliding holes 312 and fit with the slide plate 313, and there is a gap between the guide blocks 323 and the sliding holes 312.

[0040] The assembly panel 1 is rectangular and has L-shaped plates 11 fixedly arranged at the four corners. Two energy dissipation plates 12 are fixedly arranged on the L-shaped plate 11 at intervals. The plurality of assembly panels 1 form a retaining wall by engaging the L-shaped plates 11 and the energy dissipation plates 12 .

[0041] During implementation, the assembly panel 1 can be pre-made and installed in a snap-fit ​​manner, so that the installation of the reinforced earth retaining wall is faster and more convenient, and the rib 2 is connected to the assembly panel 1 through the energy-absorbing connection component 3, so that the connection point between the rib 2 and the assembly panel 1 can be offset, thereby offsetting the impact of the earthquake, avoiding the wall panel from falling off and the reinforcement from being pulled out. When an earthquake occurs, the tension generated by the vibration is decomposed into radial force and axial force through the deflection of the deflection block 33 and the sliding of the energy-absorbing block 32 along the sliding cavity 311, and the two forces are eliminated. When tension is generated between the rib 2 and the assembly panel 1, the deflection block 33 can rotate along the deflection groove 321, and the ring plate 334 can rotate along the shock-absorbing groove 322, and the deflection force is absorbed by the shock-absorbing spring 335, so that the rib 2 and the assembly panel 1 are in a straight line. The connection between the panels 1 can produce deflection, and at the same time, the energy dissipation block 32 can slide along the sliding cavity 311 and push the slide plate 313 to slide, that is, the energy dissipation block 32 can be displaced axially and absorb this axial force through the shock-absorbing spring 2 314, so as to decompose and absorb the tensile force generated by the earthquake, prevent the connection point between the rib 2 and the assembly panel 1 from breaking, causing the wall panel to fall off and the reinforcement material to be pulled out, thereby improving the stability and safety of the reinforced earth retaining wall. In addition, when an earthquake occurs, the energy dissipation plates 12 between two adjacent assembly panels 1 can be squeezed against each other, and the material of the energy dissipation plates 12 is made of a material with shock-absorbing properties, such as a rubber pad, a polyurethane foam, so that it can effectively absorb and disperse the earthquake energy during the extrusion process, reduce the vibration and damage of the panel, and further improve the stability of the reinforced earth retaining wall.

[0042] In this embodiment, Figure 6 A slip ring 1 315 is slidably arranged in the sliding hole 312, and a plurality of energy dissipation springs 316 are fixedly arranged in a circumference on the slip ring 1 315. A slip ring 2 317 is fixedly arranged at the other end of the energy dissipation spring 316, and the slip ring 2 317 is slidably connected to the guide block 323.

[0043] The slip ring 1 315 and the slip ring 2 317 are arranged so that the guide block 323 can slide radially along the slide hole 312, that is, the energy block 32 can slide radially along the slide cavity 311. When the deflection block 33 deflects along the energy block 32, the direction of the tension generated by the deflection block 33 will change. At this time, the energy block 32 will further deviate under the action of this tension, that is, it will deviate toward the side with tension, and the energy dissipation spring 316 will absorb this displacement force, thereby reducing the pressure applied to the energy block 32 by the deflection block 33, further eliminating the tension generated by the earthquake, and improving the shock-absorbing and energy-dissipating effect.

[0044] A construction method of a reinforced earth retaining wall with shock absorption and energy dissipation, comprising the following steps:

[0045] S1, clamping the assembly panel 1 together through the L-shaped plate 11 and the energy dissipation plate 12, and fixing the connecting rod 331 to the rib 2 and then fixing it to the deflection block 33;

[0046] S2, installing the assembly panel 1, the ribs 2 and the energy dissipation connection assembly 3 layer by layer, and filling and compacting the sand material at the same time until the installation of the entire reinforced soil retaining ring is completed;

[0047] S3. When an earthquake occurs, a tensile force is generated between the assembly panel 1 and the ribs 2. The energy dissipation connection assembly 3 is used to dissipate the tensile force, thereby preventing the reinforced earth retaining wall panel from falling off and the ribs from being pulled out under the influence of the earthquake;

[0048] S3.1, the deflection block 33 deflects along the energy dissipation block 32, and at the same time the ring plate 334 squeezes the damping spring 1 335, thereby offsetting the radial force generated between the rib 2 and the assembly panel 1 through this deflection force;

[0049] S3.2, while the deflection block 33 deflects along the energy absorbing block 32, the energy absorbing block 32 can slide along the sliding cavity 311, and at the same time, the guide block 323 can push the slide plate 313 to slide and squeeze the shock absorbing spring 2 314, thereby offsetting the axial force generated between the rib 2 and the assembly panel 1 through the sliding of the energy absorbing block 32;

[0050] S4. When an earthquake occurs, the energy dissipation plates 12 arranged on the plurality of assembly panels 1 can squeeze each other and absorb the squeezing force, thereby reducing the relative displacement between two adjacent assembly panels 1 and preventing the assembly panels 1 from being damaged.

[0051] To sum up, when the present invention is implemented, the connection between the rib 2 and the assembly panel 1 is no longer fixed through the arrangement of the energy-absorbing connection assembly 3. When an earthquake occurs, the tension applied by the rib 2 to the assembly panel 1 can be offset by the rotation of the deflection block 33 and the sliding absorption of the energy-absorbing block 32, that is, the deflection block 33 and the energy-absorbing block 32 can decompose the tension generated by the earthquake into radial force and axial force, and absorb and offset the radial force through the deflection of the deflection block 33 and the shock-absorbing spring 1 335, and absorb and offset the axial force through the sliding of the energy-absorbing block 32 and the shock-absorbing spring 2 314. In addition, an energy-dissipating plate 12 is arranged on the assembly panel 1, and the seismic energy between the assembly panels 1 is further absorbed and dispersed through the energy-dissipating plate 12, thereby greatly reducing the impact of the earthquake on the assembly panel 1 and the rib 2, avoiding the phenomenon of wall panel falling off and reinforcement material pulling out, and effectively improving the stability and safety of the reinforced earth retaining wall.
