Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, and in particular to a buffer structure and a retaining wall. Background Technology

[0002] Retaining walls are used to support roadbed fill or uphill soil, preventing deformation and instability. Soil expands and contracts with seasonal changes, and this effect is exacerbated by rainwater infiltration, which increases soil moisture content. Therefore, the soil pressure on retaining walls is not constant. Most existing retaining walls rely on springs for impact cushioning. However, in practical applications, adding springs significantly increases costs, and their short lifespan makes them impractical. Therefore, effective impact cushioning is a pressing issue.

[0003] For example, Chinese patent CN207582493U, entitled "A Buffer-Type Retaining Wall Block," discloses a scheme that uses lateral movement between blocks to achieve buffering and repositioning, thus solving the problem of achieving buffering without using springs. However, the blocks used have multi-faceted shapes, resulting in a large amount of work during installation.

[0004] Therefore, a buffer structure and retaining wall are proposed to address the above problems. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a buffer structure and retaining wall. The buffer block structure of this invention is simple, the stacking process is simple, and it can significantly reduce the amount of engineering work.

[0006] The technical solution to the problem solved by this utility model is as follows: This utility model provides a buffer structure, including: a plurality of buffer blocks stacked in a staggered manner, wherein the longitudinal buffer blocks are stacked along the slope of the wall back, so that the longitudinal buffer blocks are staggered; the buffer blocks are elongated, and their length extends in the front-back direction of the fixed wall. The top side of the buffer block is provided with a groove, the groove being the same length as the buffer block. The bottom side of the buffer block is connected to a convex rail, the convex rail being the same length as the buffer block, and the convex rail can be embedded in the groove. When stacked, the convex rail of the upper buffer block is inserted into the groove of the lower buffer block, thereby limiting the displacement of the upper and lower buffer blocks, making the tendency of the buffer block to slide back and forth along the groove and convex rail greater than the tendency to slide left and right, and increasing the contact area between the upper and lower buffer blocks, thereby increasing the friction force, so that the buffer block can absorb more kinetic energy when moving. The buffer block is provided with two countersunk holes, the countersunk holes communicating with the groove, the countersunk holes penetrating the convex rail, and the countersunk holes being inclined with the same slope as the wall back of the fixed wall, so as to facilitate the insertion of reinforcing bars in the countersunk holes. As shown in Figures 1 and 2, each buffer block has two countersunk holes spaced apart. One countersunk hole, along with the countersunk hole in the buffer block above it, encapsulates a reinforcing bar. The other countersunk hole, along with the countersunk hole in the buffer block below it, also encapsulates a reinforcing bar. The elasticity of the reinforcing bars allows the upper and lower buffer blocks to return to their original positions. Because the buffer blocks are stacked in a staggered manner, a long reinforcing bar cannot completely penetrate from top to bottom. Therefore, the long reinforcing bar is broken into multiple short reinforcing bars, which are only used to connect the upper and lower buffer blocks.

[0007] As an optimization, the upper end of the reinforcing bar is sealed and fixed to the buffer block by concrete encapsulation. After the concrete encapsulation solidifies, the end of the reinforcing bar can be fixed, thereby confining the reinforcing bar within the two buffer blocks. Furthermore, the buffer blocks are pre-cast concrete, so the use of concrete encapsulation provides good fixation due to the identical material.

[0008] As an optimization, the buffer block is provided with a horizontal hole, which matches a transverse connecting rod. The buffer blocks are connected horizontally by the transverse connecting rod, which further enhances the overall stability of the retaining wall, prevents the buffer blocks from shifting or tilting in the horizontal direction, and enables the retaining wall to maintain stability better when subjected to lateral pressure, thereby improving its resistance to lateral deformation.

[0009] As an optimization, one end of the transverse connecting rod is connected to a plug, and the other end of the transverse connecting rod is provided with a slot that matches the plug. This facilitates the connection and disassembly of the transverse connecting rods, improving the assembly and maintenance efficiency of the retaining wall. Through the cooperation of the plug and the slot, the transverse connecting rods can be quickly connected together to form a stable horizontal connection structure, further enhancing the integrity of the retaining wall.

[0010] As an optimization, the transverse connecting rod is provided with at least one hidden groove corresponding to the slot. A circular plate is provided in the hidden groove, and a spring and a positioning pin are connected to the circular plate. The spring is looped around the positioning pin and is connected to the transverse connecting rod. The lower end of the positioning pin passes through the connecting rod and is positioned in the slot. The insert block is provided with a positioning hole that matches the positioning pin. The positioning pin is inserted into the positioning hole to firmly connect the transverse connecting rods together.

[0011] As an optimization, some of the buffer blocks are equipped with drainage holes, which are inclined. Corresponding through holes with the same inclination angle should be provided in the fixed wall for installing drainage pipes. This effectively drains accumulated water from the retaining wall, preventing it from affecting the stability of the retaining wall.

[0012] A retaining wall is characterized by comprising a fixed wall body, a wall top, and a base; the slope of the fixed wall body is greater than the slope of the wall back; the fixed wall body has a gravity retaining wall structure that is narrower at the top and wider at the bottom; one end of the buffer block abuts against the wall back of the fixed wall body; the wall top and the base are jointly installed on the top of the fixed wall body and the uppermost buffer block; and the base is jointly installed on the bottom of the fixed wall body and the lowermost buffer block.

[0013] As an optimization, the base forms a wall toe on the wall face side and a wall heel on the wall back side. The structural design of the wall toe and heel increases the contact area between the base and the ground, improving the stability of the base and thus providing a more solid supporting foundation for the entire retaining wall. The shape and size of the wall toe and heel can be adjusted according to factors such as the height, slope, and geological conditions of the retaining wall to meet different engineering needs and ensure the stability and reliability of the retaining wall in various complex environments.

[0014] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0015] (1) The structure of the buffer block of this utility model can convert the impact force of the soil into relative displacement between the buffer blocks, so as to compress the joint between the buffer block and the wall back. The buffer blocks can absorb a large amount of kinetic energy through friction and the rigidity of the steel bars, thereby avoiding the soil from directly damaging the fixed wall. After the impact of the soil is reduced, the elasticity of the steel bars and the splicing force between the buffer block and the wall back can react on the buffer block to reset it.

[0016] (2) The buffer block of this utility model is connected in the horizontal direction by a transverse connecting rod, which enhances the integrity of the retaining wall and prevents the buffer block from shifting or tilting in the horizontal direction.

[0017] (3) The structure of the slow-moving block of this utility model is simple and the stacking process is simple, which can significantly reduce the amount of work. Attached Figure Description

[0029] like Figures 1 to 8As shown in Embodiment 1: A buffer structure includes: a plurality of buffer blocks 3 stacked vertically in a staggered manner. The buffer blocks 3 are stacked longitudinally along the slope of a wall back, resulting in a staggered arrangement between them. Each buffer block 3 is elongated, extending in the front-back direction of the fixed wall 1. A groove 7 is provided on the top side of each buffer block 3, the groove 7 being the same length as the buffer block 3. A convex rail 8 is connected to the bottom side of each buffer block 3, the convex rail 8 being the same length as the buffer block 3 and capable of being embedded in the groove 7. During stacking, the convex rail 8 of the upper buffer block 3 is inserted into the groove 7 of the lower buffer block 3, thereby limiting the displacement of the upper and lower buffer blocks 3. This makes the tendency of the buffer block 3 to slide back and forth along the groove 7 and convex rail 8 greater than its tendency to slide left and right, and increases the contact area between the upper and lower buffer blocks 3, thus increasing friction and allowing the buffer block 3 to absorb more kinetic energy when moving. The buffer block 3 is provided with two countersunk holes 9, which connect to the groove 7 and penetrate the protruding rail 8. The countersunk holes 9 are inclined with the same slope as the wall back slope of the fixed wall 1 to facilitate the insertion of the reinforcing bar 10 into the countersunk holes 9. Figure 3 and Figure 4 As shown, the buffer block 3 has two countersunk holes 9 spaced apart. One countersunk hole 9, together with the countersunk hole 9 of the buffer block 3 above it, encapsulates a steel bar 10. The other countersunk hole 9, together with the countersunk hole 9 of the buffer block 3 below it, also encapsulates a steel bar 10. The elasticity of the steel bar 10 allows the upper and lower buffer blocks 3 to return to their original positions. Since the buffer blocks 3 are stacked in a staggered manner, it is difficult for a long steel bar to completely penetrate from top to bottom. Therefore, the long steel bar is broken into multiple short steel bars, which only connect the upper and lower buffer blocks 3.

[0030] The upper end of the reinforcing bar 10 is sealed and fixed to the buffer block 3 by a concrete encapsulation 11. After the concrete encapsulation 11 solidifies, the end of the reinforcing bar 10 can be fixed, thereby confining the reinforcing bar 10 within the two buffer blocks 2. Furthermore, the buffer block 2 is precast concrete, so the use of concrete encapsulation 11 provides good fixation due to the same material.

[0031] The buffer block 3 is provided with drainage holes, which are inclined. The fixed wall 1 should have a through hole with the same inclination angle as the drainage hole for installing a drainage pipe. This can effectively drain the water accumulated in the retaining wall and prevent the water from affecting the stability of the retaining wall.

[0032] The drainage pipes are spaced 2-3 meters apart, with staggered upper and lower rows, and use 10cm thick PVC pipes. The bottom row of drainage pipes should be 30cm above the ground level; if it is a retaining wall along a river or in a flooded area, it should be 30cm above the normal water level.

[0033] Example 2: This example further elaborates on Example 1. The buffer block 3 is provided with a horizontal hole 12, which matches a transverse connecting rod 13. The buffer blocks 3 are connected horizontally by the transverse connecting rod 13, further enhancing the overall stability of the retaining wall, preventing the buffer blocks 3 from shifting or tilting in the horizontal direction, and enabling the retaining wall to maintain stability better when subjected to lateral pressure, thereby improving its resistance to lateral deformation.

[0034] One end of the transverse connecting rod 13 is connected to a plug 15, and the other end of the transverse connecting rod 13 is provided with a slot 20 that matches the plug 15. This facilitates the connection and disassembly of the transverse connecting rods 13, improving the assembly and maintenance efficiency of the retaining wall. Through the cooperation of the plug 15 and the slot 20, the transverse connecting rods 13 can be quickly connected together to form a stable horizontal connection structure, further enhancing the integrity of the retaining wall.

[0035] The transverse connecting rod 13 is provided with at least one hidden groove 16 corresponding to the slot 20. A circular plate 17 is provided in the hidden groove 16. The circular plate 17 is connected to a spring 18 and a positioning pin 19. The spring 18 is looped around the positioning pin 19 and is connected to the transverse connecting rod 13. The lower end of the positioning pin 19 passes through the connecting rod 13 and is located in the slot 20. The insert block 15 is provided with a positioning hole 14 that matches the positioning pin 19. The positioning pin 19 is inserted into the positioning hole 14 to firmly connect the transverse connecting rod 13 together.

[0036] The workflow of this embodiment is as follows:

[0037] After the buffer blocks 3 are stacked, the transverse connecting rod 13 is passed through the transverse hole 12 to install the transverse connecting rod 13. When connecting the transverse connecting rod 13, the circular plate 17 is pulled outward by hand. The circular plate 17 stretches the spring 18. The circular plate 17 drives the positioning pin 19 to move, so that the positioning pin 19 is flush with the slot 20. The next insert block 15 connected to the transverse connecting rod 13 is fully inserted into the slot 20. The circular plate 17 is released, the spring 18 returns to its original state, and the positioning pin 19 is inserted into the positioning hole 14.

[0038] A retaining wall is characterized by comprising a fixed wall body 1, a wall top 2, and a base 4. The slope of the fixed wall body 1 is greater than the slope of the wall back, and the fixed wall body 1 has a gravity retaining wall structure that is narrower at the top and wider at the bottom. One end of the buffer block 3 abuts against the wall back of the fixed wall body 1. The wall top 2 and the base 4 are installed together on the top of the fixed wall body 1 and the uppermost buffer block 3, and the base 4 is installed together on the bottom of the fixed wall body 1 and the lowermost buffer block 3.

[0039] Fixed wall 1 should be constructed in sections, each 10-15m long, with expansion joints between sections. Settlement joints should be installed where there are significant changes in terrain, geology, or wall height. Expansion joints and settlement joints should be 2cm wide and filled with mortar. The inner, outer, and top sides of the joints should be filled with asphalt-impregnated hemp, 15cm into the wall.

[0040] Fixed wall 1 is constructed using C25 rubble concrete.

[0041] The base 4 forms a wall toe 6 on the wall-facing side and a wall heel 5 on the wall-backing side. The structural design of the wall toe 6 and wall heel 5 increases the contact area between the base 4 and the ground, improving the stability of the base 4 and thus providing a more solid supporting foundation for the entire retaining wall. The shape and size of the wall toe 6 and wall heel 5 can be adjusted according to factors such as the height, slope, and geological conditions of the retaining wall to meet different engineering needs and ensure the stability and reliability of the retaining wall in various complex environments.

[0042] The workflow of this embodiment is as follows:

[0043] The fixed wall 1 can be constructed using traditional methods by pouring concrete. First, the fixed wall 1 is poured on the base 4. After the fixed wall 1 is formed, pre-made buffer blocks 3 are stacked sequentially from bottom to top against the wall back. During this process, steel bars 10 are embedded in the corresponding countersunk holes 9 with each layer, and the upper ends of the steel bars 10 are sealed with concrete and smoothed to form a concrete seal 11, preventing the protruding rails 8 from failing to embed into the grooves 7. After stacking to the top of the fixed wall 1, it is fixed using wall caps 2.

[0044] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
