Description

Technical Field

[0001] This utility model belongs to the field of retaining wall technology, specifically relating to an anti-slip reinforced retaining wall. Background Technology

[0002] A reinforced retaining wall is a type of retaining wall that enhances soil stability through the interaction between reinforcing materials (such as strip reinforcement, geogrid, etc.) and the fill soil.

[0003] Existing reinforced retaining walls have high requirements for foundation strength. The bearing capacity and stability of the foundation directly affect the safety of the wall. If the foundation is not properly treated, the wall is prone to instability. In addition, compared with other types of retaining walls, existing reinforced retaining walls have relatively low bearing capacity and are prone to displacement or collapse under the action of soil piles. Specifically, the bearing capacity of reinforced retaining walls within the rammed earth layer is poor, so they can only be used in relatively flat areas, thus limiting their applicability. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes an anti-sliding reinforced retaining wall. In this invention, when the soil pile pushes the retaining plate forward, the rammed earth in the rammed earth layer is pushed into the soil storage area formed by the pressure plate and the two side plates, thereby generating a downward pressure on the pressure plate. This, in turn, causes the retaining wall to exert downward pressure on the foundation and gradually sink, increasing the friction between the retaining wall and the foundation. This reduces or prevents the retaining wall from continuing to move, avoiding displacement or collapse, and thus preventing the soil pile from becoming unstable.

[0005] According to some embodiments, this utility model provides an anti-sliding reinforced retaining wall, which adopts the following technical solution:

[0006] An anti-sliding reinforced retaining wall includes a pressure plate, a baffle, and side plates inclinedly arranged on both sides of the baffle.

[0007] The two side plates are brought together on the side away from the baffle; one end of each side plate extends out of one end of the baffle, and guide grooves are respectively opened at the positions where the two side plates extend out of the baffle; the two ends of the pressure plate can be respectively inserted into the two guide grooves.

[0008] Furthermore, the side plate is a trapezoidal plate.

[0009] Furthermore, the guide groove slopes downward from the end closest to the baffle to the end furthest from the baffle.

[0010] Furthermore, the baffle is provided with a plurality of buttresses, and a base plate is provided at one end of the buttresses near the buttress.

[0011] Furthermore, both the buttress panel and the side panel are provided with connecting holes, and ribs are provided in the connecting holes.

[0012] Furthermore, the baffle is an arc-shaped baffle, and the rib is an arc-shaped rib.

[0013] Furthermore, the baffle is a planar baffle, and the rib is a straight rib.

[0014] Furthermore, the pressure plate has multiple rib grooves on its body.

[0015] Furthermore, the guide groove and the pressure plate are installed in the rammed earth layer of the foundation pit.

[0016] Furthermore, concrete is laid on top of the rammed earth inside the foundation pit.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model features side plates inclined on both sides of a baffle, with the sides of the two side plates furthest from the baffle approaching each other. One end of each side plate extends beyond one end of the pressure plate, and guide grooves are inclinedly formed at the points where the side plates extend beyond the pressure plate. The two ends of the pressure plate can be inserted into the two guide grooves respectively. In use, when the soil pile pushes the baffle forward, the rammed soil in the rammed soil layer is pushed into the soil storage area formed by the pressure plate and the two side plates, thereby generating a downward pressure force on the pressure plate. This causes the retaining wall to exert downward pressure on the foundation and gradually sink, increasing the friction between the retaining wall and the foundation. This reduces or prevents the retaining wall from moving further, avoiding displacement or collapse of the retaining wall, and thus preventing the soil pile from becoming unstable.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] Retaining walls are supporting structures used in civil engineering to stabilize soil or fill material. Their core function is to resist lateral pressure on the soil through their own structure, preventing landslides or deformation instability. The main types include gravity retaining walls, cantilever retaining walls, buttress retaining walls, anchored retaining walls, and reinforced retaining walls. Reinforced retaining walls are a type of retaining wall that enhances soil stability through the interaction between reinforcing materials (such as strip reinforcing bars, geogrids, etc.) and the fill material.

[0030] Existing reinforced retaining walls have high requirements for foundation strength. The bearing capacity and stability of the foundation directly affect the safety of the wall. If the foundation is not properly treated, the wall is prone to instability. In addition, compared with other types of retaining walls, existing reinforced retaining walls have relatively low bearing capacity and are prone to displacement or collapse under the action of soil piles. Therefore, they can only be used in relatively flat areas, thus limiting their applicability.

[0031] To solve at least one of the above problems, such as Figure 1 and Figure 3 As shown, this application provides an anti-sliding reinforced retaining wall, including side plates 1, baffles, bottom plates 4, wall panels, reinforcing bars, and pressure plates 8.

[0032] In one embodiment, the side plate 1 is a trapezoidal plate, with the end for embedding in the foundation 12 having a longer bottom base, which can ensure the foundation area with the rammed earth 11 and concrete 10 in the foundation 12, thus ensuring stability. As the height of the soil mound increases, its soil volume continuously decreases, and the force on the retaining wall also decreases. Based on this, the area of ​​the side plate 1 located outside the foundation 12 decreases as the height increases, saving materials while still satisfying the retaining effect.

[0033] In other embodiments, the side plate 1 may also be configured as a rectangular plate, a triangular plate, a plate of other regular shapes, or a plate-like object of irregular shapes.

[0034] like Figure 1 As shown, in one embodiment, side plates 1 are provided on both sides of the baffle, and the two side plates 1 away from the baffle are brought together to accommodate the installation of the pressure plate 8. The baffle is an arc-shaped baffle 2. By setting the arc-shaped baffle 2, the force in the middle of the soil pile can be dispersed to both sides; when the amount of soil in the middle of the soil pile is large and the force acting on the middle of the baffle wall is large, the force on the baffle wall can be reduced.

[0035] like Figure 2 As shown, in another embodiment, the baffle is a flat baffle 3. By setting the flat baffle 3, the soil pile can be blocked effectively. When the soil volume distribution in each part of the soil pile is relatively uniform, the force acting on each part of the baffle wall is not much different. At this time, the flat baffle 3 can play a better blocking role for the soil pile as a whole.

[0036] The baffle is provided with multiple buttresses, and a base plate 4 is provided between the multiple buttresses and the baffle. The buttresses can be set as trapezoidal plates, and the base plate 4 can be set at an inclination or at a horizontal position, which can be adjusted according to the needs. The buttresses and the base plate 4 are set to increase the structural strength and stability of the retaining wall.

[0037] like Figure 1 and Figure 3 As shown, when the baffle is an arc-shaped baffle 2, the buttress is a first buttress 5; when the baffle is a flat baffle 3, the buttress is a second buttress 9.

[0038] Both the buttress panel and the side plate 1 are provided with multiple connecting holes 102. Reinforcing bars are installed through these connecting holes 102. The reinforcing bars can be one or multiple parallel bars, connecting the buttress panel and the side plate 1, further increasing the structural strength of the retaining wall. When the retaining plate is an arc-shaped retaining plate 2, the reinforcing bars are arc-shaped reinforcing bars 6, matching the arc-shaped retaining plate 2; when the retaining plate is a flat retaining plate 3, the reinforcing bars are straight reinforcing bars 7, matching the flat retaining plate 3. After passing through the connecting holes 102, the reinforcing bars can be fixed or connected by welding or other connection methods.

[0039] like Figure 3 and Figure 4 As shown, one end of each of the two side plates 1 extends out of one end of the baffle, and guide grooves 101 are respectively inclinedly provided at the positions where the two side plates 1 extend out of the baffle; the two ends of the pressure plate 8 can be respectively inserted into the two guide grooves 101.

[0040] Understandable, such as Figure 5 As shown, the pressure plate 8 is inserted into the guide groove 101 on one side of the baffle. Because the two side plates 1, away from the baffle, move towards each other, the two ends of the pressure plate 8 can extend out of the guide groove 101. Furthermore, after being inserted to a certain extent, the front sidewall of the pressure plate 8 can contact the inner wall of the guide groove 101, thus limiting the position of the pressure plate 8. It is understandable that... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the distance between the front ends of the two guide grooves 101 is 'a', and the distance between the rear ends of the two guide grooves 101 is 'b'. Therefore, a > b, and the left-right length of the pressure plate 8 is less than a but greater than b. Let the vertical distance between the front and rear ends of each guide groove 101 be 'c', and the front-rear length of the pressure plate 8 be greater than 'c'.

[0041] In use, the pressure plate 8 can be pre-set in the guide groove 101 and then welded, and then the entire retaining wall can be buried in the foundation pit 121 of the foundation 12. Alternatively, the other parts of the retaining wall, excluding the pressure plate 8, can be buried in the foundation pit 121 and the soil 11 can be compacted first, and then the pressure plate 8 can be hammered into the compacted soil and inserted into the guide groove 101 by hammering or other means, and finally fixed by welding or other operations.

[0042] The guide groove 101, with its end furthest from the baffle gradually decreasing in height, achieves an inclined configuration. After the pressure plate 8 is inserted into the guide groove 101, a soil storage area 13 is formed between the bottom plate 4, the pressure plate 8, and the two side plates 1. The soil storage area 13 is a fan-shaped soil storage area. Figure 6As shown, when the soil pile pushes the baffle forward, some of the rammed soil in the rammed soil layer is pushed into the soil storage area 13, which in turn exerts a downward pressure on the pressure plate 8. This causes the retaining wall to exert downward pressure on the foundation 12 and gradually sink, increasing the friction between the retaining wall and the foundation 12. This reduces or prevents the retaining wall from moving further, avoiding displacement or collapse of the retaining wall and preventing the soil pile from becoming unstable.

[0043] like Figure 3 and Figure 4 As shown, the plate 801 of the pressure plate 85 is provided with multiple rib grooves 802. The multiple rib grooves 802 can increase the friction between the pressure plate 85 and the compacted soil 11, and improve the interaction effect. The rib grooves 802 can also be through holes, allowing some of the compacted soil 11 to pass through, avoiding damage to the pressure plate 85 when the instantaneous force of the compacted soil 11 increases.

[0044] Optionally, during use, the guide groove 101 and the pressure plate 8 are installed in the rammed earth layer of the foundation pit 12, allowing some of the rammed earth to smoothly enter the storage area 13. Inside the foundation pit 12, concrete 10 is placed on top of the rammed earth 11, further improving the stability of the retaining wall on the foundation 12. Multiple buttress plates 5 form a filling grid 14, which can be filled with materials such as stones to ensure the connection stability between the filling material and the retaining wall.

[0045] One of the working processes of the retaining wall in this embodiment is as follows:

[0046] Depending on the terrain and stress conditions, either an arc-shaped retaining wall 2 or a flat retaining wall 3 is selected. Generally, since the load-bearing capacity of the arc-shaped retaining wall assembly is higher than that of the flat retaining wall assembly, if the load-bearing capacity requirement of the construction area is not high, the flat retaining wall 3 is selected; otherwise, the arc-shaped retaining wall 2 is selected. A foundation pit 121 is excavated on the foundation 12. The bottom of the retaining wall is then lowered into the foundation pit 121, with the outer wall of the arc-shaped retaining wall 2 or the flat retaining wall 3 facing the soil mound, while ensuring that the bottom plate 4 sinks to the bottom of the foundation pit 121. During the lowering of the retaining wall, the lower parts of the two side plates 1 are inserted into the rammed earth 11 located below the foundation pit 121; at this time, the pressure plate 8 has not yet been installed between the two side plates 1. The pressure plate 8 is placed at an angle in the foundation pit 121, positioned on one side of the soil pile. Then, the pressure plate 8 is inserted downwards into the rammed earth 11, positioned between the lower parts of the two side plates 1. The rear edges of the pressure plate 8 gradually extend into the front ends of the two guide grooves 101. To overcome the resistance of the rammed earth 11 to the pressure plate 8, a hammer is used to strike the front edge of the pressure plate 8, causing it to move further downwards and backwards. This moves the rear edge of the pressure plate 8 towards the rear end of the two guide grooves 101, while the front part of the pressure plate 8 gradually enters the two guide grooves 101. When the rear edge of the pressure plate 8 abuts against the rear ends of the two guide grooves 101, the pressure plate 8 can no longer move. At this time, the front edge of the pressure plate 8 is located below the front edge of the base plate 4. The front edge of the pressure plate 8 is fixed to the front edge of the base plate 4 by welding. Concrete 10 is poured into the foundation pit 121. After the concrete 10 has completely solidified, it will firmly fix the retaining wall to the foundation 12. The outer wall of the arc-shaped baffle 2 or the flat baffle 3 will then block the soil pile. Finally, stones or soil blocks are filled into each filling grid 14 to increase strength and weight. After multiple retaining walls are constructed in the same way according to the terrain, the two ends of each arc-shaped rib 6 or each straight rib 7 on each retaining wall are welded to a corresponding arc-shaped rib 6 or a straight rib 7 on two adjacent retaining walls to fix them together. This will fix the multiple retaining walls together.

[0047] Understandably, when the soil pile applies pressure to the retaining wall, it will force the retaining wall to move in the direction of the soil pile's thrust. However, since the pressure plate 8 is inserted at an angle into the rammed earth 11, when the pressure plate 8 moves with the retaining wall, the rear edge of the pressure plate 8 will force the rammed earth 11 around it to enter the soil storage area 13, thereby generating a downward pressure force on the pressure plate 8. This will cause the retaining wall to exert downward pressure on the foundation 12 and gradually sink, thereby increasing the friction between the retaining wall and the foundation 12, thus reducing or preventing the retaining wall from continuing to move, and thus playing a role in preventing the soil pile from becoming unstable.

[0048] This invention significantly increases the bonding force between the wall and the foundation 12 by utilizing the cooperation between the pressure plate 8 and the two side plates 1. This allows the wall to convert the lateral thrust into downward pressure when subjected to the thrust of the soil pile, thereby increasing the friction between the wall and the foundation 12. Simultaneously, it automatically generates a sinking tendency so that the bottom of the wall penetrates deep into the foundation 12, thus reducing the strength requirements of the foundation and effectively preventing instability. In addition, it significantly enhances the load-bearing capacity of the wall to prevent displacement or collapse, thereby expanding its applicability to areas with relatively steep terrain.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
