Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically a slope protection wall. Background Technology

[0002] In engineering construction, slopes are an important structural element, but their stability is easily affected by internal and external factors. For example, loose soil and external loads can lead to slope instability and thus safety accidents. Support structures can effectively increase the bearing capacity of slopes, improve their stability, and prevent instability accidents.

[0003] Chinese patent discloses a slope support wall with buffer function (authorization announcement number CN221721677U). This patented technology adopts a novel structural design and sets up a buffer component. The buffer component is set between the support plate and the fixed base plate. The buffer component is set up as an outer sleeve and a movable rod that slide against each other. When the support plate is subjected to pressure, the support plate rotates and squeezes the buffer component. At this time, the air inside the outer sleeve is used to achieve the purpose of buffering and increase the effectiveness of the device. However, the stability of the wall and the slope is not good, and the wall is prone to instability. Utility Model Content

[0004] The purpose of this utility model is to provide a slope protection wall to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A slope protection wall includes a foundation layer and a wall body fixedly connected to the foundation layer. An anti-erosion layer is provided on the back side of the wall body, and a filter layer is provided on one side of the anti-erosion layer. An upper waterproof layer is provided on the back side of the wall body above the anti-erosion layer and the filter layer, and a lower waterproof layer is provided on the back side of the wall body below the anti-erosion layer and the filter layer. Several drainage holes are inclined downward inside the wall body, and several reserved holes are provided at the upper part of the interior of the wall body. An anchor assembly is installed inclined upward inside each reserved hole.

[0007] As a further improvement of this utility model: the filter layer is a pebble structure component, and the anti-erosion layer is a geotextile component.

[0008] As a further embodiment of this utility model: both the upper and lower waterproof layers are two-layer structures, with the upper layer being a clay layer and the lower layer being a polyethylene film.

[0009] As a further embodiment of this utility model: the anchor assembly includes an anchor pipe and a tie rod that penetrates the interior of the anchor pipe. The upper end of the tie rod is fixedly connected to a limiting head, and an anchor is sleeved at the lower end of the tie rod. A clamp is sleeved between the tie rod and the anchor.

[0010] As a further improvement of this utility model: the upper part of the anchor pipe is located inside the slope, and the lower part of the anchor pipe is located inside the reserved hole.

[0011] As a further improvement of this utility model: several overflow holes are provided on the outer side of the anchor pipe, and a grouting hole is provided at the lower end of the outer side of the anchor pipe. A limit ring is fixedly connected to the outer side of the anchor pipe near the grouting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a filter layer to trap coarse soil particles flowing with water inside the slope, and an anti-erosion layer to trap fine soil particles that have permeated through the filter layer, thus preventing water from accumulating on the back of the wall and causing slope erosion, deformation, or even displacement and collapse. The upper waterproof layer prevents large amounts of rainwater from seeping into the slope, and the lower waterproof layer prevents groundwater from rising into the slope, thus avoiding excessive water pressure on the wall. By injecting cement mortar into the anchoring assembly, the tie rods, anchor pipes, and slope are bonded together, enabling anchoring of the wall through the anchor pipes and tie rods, thereby improving the overall strength of the retaining wall and the slope.

[0019] Please see Figures 1-4 In this embodiment of the utility model, a slope protection wall includes a base layer 1 and a wall 2 fixedly connected to the base layer 1. An anti-erosion layer 9 is provided on the back side of the wall 2, and a filter layer 7 is provided on one side of the anti-erosion layer 9. An upper waterproof layer 5 is provided on the back side of the wall 2 above the anti-erosion layer 9 and the filter layer 7, and a lower waterproof layer 8 is provided on the back side of the wall 2 below the anti-erosion layer 9 and the filter layer 7. Several drainage holes 3 are inclined downward inside the wall 2, and several reserved holes 4 are provided at the upper part of the interior of the wall 2. An anchor assembly 6 is installed inclined upward inside each reserved hole 4.

[0020] Preferably, the filter layer 7 is a pebble structure component, and the anti-erosion layer 9 is a geotextile component. The filter layer 7 can intercept the coarse soil particles flowing with the water inside the slope, allowing the water to flow smoothly. The anti-erosion layer 9 can intercept the fine soil particles that pass through the filter layer 7, allowing the water to flow smoothly. This allows the water to be discharged from the drainage hole 3 without soil erosion, preventing water from accumulating on the back of the wall 2 and causing slope erosion, deformation, or even displacement and collapse.

[0021] Preferably, both the upper waterproof layer 5 and the lower waterproof layer 8 are two-layer structures, with the upper layer being a clay layer and the lower layer being a polyethylene film. The upper waterproof layer 5 can prevent a large amount of rainwater from seeping into the slope and causing excessive pressure on the wall 2. The lower waterproof layer 8 can prevent groundwater from entering the slope and causing excessive pressure on the wall 2.

[0022] exist Figure 3 and Figure 4In the process, the anchor assembly 6 includes an anchor pipe 61 and a tie rod 66 penetrating the interior of the anchor pipe 61. A limiting head 67 is fixedly connected to the upper end of the tie rod 66, and an anchor 63 is sleeved on the lower end of the tie rod 66. A clamp 64 is sleeved between the tie rod 66 and the anchor 63. The upper part of the anchor pipe 61 is located inside the slope, and the lower part is located inside the pre-drilled hole 4. Before constructing the slope support wall, the anchor pipe 61 and the tie rod 66 are driven into the slope. Then, the anchor 63 is embedded in the lower end of the anchor pipe 61. After tightening the tie rod 66 with external force, the clamp 64 is clamped between the anchor 63 and the tie rod 66. After the external force on the tie rod 66 is removed, the tie rod 66 springs back and pulls the clamp 64 towards the inside of the anchor 63, thereby securely fixing the tie rod 66 and the anchor pipe 61. Together; several overflow holes 65 are opened on the outer side of the anchor pipe 61, and a grouting hole 68 is provided at the lower end of the outer side of the anchor pipe 61. A limiting ring 62 is fixedly connected to the outer side of the anchor pipe 61 near the grouting hole 68. The limiting ring 62 can limit the distance that the anchor pipe 61 can extend into the reserved hole 4, so that the grouting hole 68 is close to the wall side of the wall 2. After the slope support wall is constructed, cement mortar is injected into the anchor pipe 61 through the grouting hole 68 using external grouting equipment. A part of the cement mortar seeps into the interior of the slope from the overflow hole 65. After the mortar solidifies, the tie rod 66, the anchor pipe 61 and the slope are solidified together. The wall 2 is anchored by the anchor pipe 61 and the tie rod 66, which can improve the overall strength of the support wall and the slope, thereby improving the ability of the wall 2 to resist deformation pressure.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
