Description

Technical Field

[0001] This utility model relates to the field of slope treatment technology, specifically to a self-stabilizing gravity retaining wall structure for slope landslide treatment. Background Technology

[0002] Slope landslide control refers to a systematic approach that combines engineering and non-engineering measures to stabilize and prevent landslides that have occurred or have potential risks. Its core objective is to eliminate or mitigate the threat of landslides to human activities and the natural environment. Gravity retaining walls are a common retaining structure in slope control. In practical slope management projects, a frequent challenge is drainage of the slope behind the retaining wall. Both rainwater and seepage from the slope can negatively impact the retaining wall structure, especially water, which creates additional water pressure, leading to changes in the wall's stress and a continuous decrease in its bearing capacity, potentially causing instability. Therefore, this case study addresses these issues in depth. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a self-stabilizing gravity retaining wall structure for slope landslide control, solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-stabilizing gravity retaining wall structure for slope landslide control, comprising concrete piles embedded at the foot of the slope, a wall foundation constructed on top of the concrete piles, the wall foundation having a conical cross-section with one lower end at an acute angle on one side of the slope, a vertical retaining wall integrally cast on the wall foundation, permeable holes provided along the inclined direction on the vertical retaining wall, seepage guiding components inserted into the permeable holes, and the side of the vertical retaining wall... A pressure-bearing protrusion is constructed on one side of the slope. The pressure-bearing protrusion and the upper part of the seepage diversion component are backfilled with sand and gravel to form a sand and gravel permeable zone. The top of the sand and gravel permeable zone is filled with gravel and compacted to form a gravel zone. Geotextile is laid at the bottom of the sand and gravel permeable zone. The slope soil is backfilled on the gravel zone to form a soil zone. A concrete slope is set on the top of the soil zone along the inclined direction. A water-blocking ditch is set on the top of the vertical retaining wall near the bottom of the concrete slope. An open channel drainage ditch is constructed on the lower part of the vertical retaining wall above the wall foundation.

[0005] The aforementioned water permeation guiding component includes a permeable flower pipe arranged along an inclined direction. The outside of the permeable flower pipe is covered with a filter cloth, and a water guide pipe is provided at one end of the permeable flower pipe, which is inserted into the permeable hole.

[0006] A diversion ditch is constructed along the slope direction on the aforementioned concrete slope.

[0007] A stepped gabion mesh is constructed on the side of the slope toe near the wall foundation, and the gabion mesh is filled with crushed stone.

[0008] A diagonal tie bar is provided between the wall foundation and the gabion mesh. One end of the diagonal tie bar is anchored in the wall foundation, and the other end is inserted into the gabion mesh and welded with a cross-shaped limiting block. Beneficial effects

[0009] This invention provides a self-stabilizing gravity retaining wall structure for slope landslide control. The self-stabilizing gravity retaining wall structure used for slope landslide control has the following beneficial effects: Concrete piles are driven into the lower part of the slope foot to provide stable support for the retaining wall. The wall foundation is poured on the concrete piles, and the acute end of the wall foundation is compacted by backfilling with soil and rocks to improve the stability of the wall foundation. A vertical retaining wall is integrally cast on the wall foundation as the main body of slope protection. With the bearing protrusions under the backfilled soil and rocks, it can effectively resist the sliding force of the slope soil and rocks. The entire retaining wall achieves self-stabilization under the action of gravity and the pressure of the upper soil and rocks. The seepage diversion components are used to quickly divert the seepage water flowing out of the slope, preventing water from accumulating between the slope and the vertical retaining wall. At the same time, with the cooperation of the top concrete slope, water-blocking ditch and open drainage ditch, surface runoff can be quickly discharged, reducing the erosive impact of surface runoff on the retaining wall and further improving the overall reliability of the retaining wall structure.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Refer to the appendix of the instruction manual Figure 1-3 As can be seen, this application specifically designs a self-stabilizing gravity retaining wall structure for landslide control of slope 1, including concrete piles 2 embedded at the foot of slope 1, a wall foundation 3 constructed on top of the concrete piles 2, the wall foundation 3 having a conical cross-section with one end at an acute angle on one side of slope 1, a vertical retaining wall 4 integrally cast on the wall foundation 3, permeable holes 5 provided along the inclined direction on the vertical retaining wall 4, and seepage guiding components inserted into the permeable holes 5, the side of the vertical retaining wall 4 located at... A pressure-bearing protrusion 6 is constructed on one side of slope 1. The area above the pressure-bearing protrusion 6 and the seepage diversion structure is backfilled with sand and gravel to form a sand and gravel permeable zone 7. The top of the sand and gravel permeable zone 7 is filled with gravel and compacted to form a gravel zone 8. Geotextile 9 is laid at the bottom of the sand and gravel permeable zone 7. Soil from slope 1 is backfilled above the gravel zone 8 to form a soil zone 10. A concrete slope surface 11 is set on the top of the soil zone 10 along the inclined direction. A water-retaining ditch 12 is set at the bottom of the vertical retaining wall 4 near the concrete slope surface 11. Below the vertical retaining wall 4... A drainage ditch 13 is constructed above the wall foundation 3. Concrete piles 2 are driven into the lower part of the slope 1 to provide stable support for the retaining wall. The wall foundation 3 is poured on the concrete piles 2. The wall foundation 3 has a conical cross-section, and the upper part of the acute angle end is backfilled with soil and rocks and compacted to improve the stability of the wall foundation 3. A vertical retaining wall 4 is integrally cast on the wall foundation 3 as the main body of slope protection 1. Together with the bearing protrusion 6 under the backfilled soil and rocks, it can provide... Effectively resisting the sliding force of soil and rock on slope 1, the entire retaining wall achieves self-stabilization under the action of gravity and the pressure of the upper soil and rock; the seepage diversion component is used to quickly divert the seepage water flowing out of slope 1, avoiding the accumulation of water between slope 1 and vertical retaining wall 4; at the same time, in conjunction with the top concrete slope 11, water-blocking ditch 12 and open drainage ditch, surface runoff can be quickly discharged, reducing the erosive impact of surface runoff on the retaining wall, and further improving the overall reliability of the retaining wall structure.

[0016] In the specific implementation process, the above-mentioned seepage diversion component includes a permeable flower pipe 14 arranged along the inclined direction. The permeable flower pipe 14 is covered with a filter cloth 15 on the outside. A water guide pipe 16 is provided at one end of the permeable flower pipe 14. The water guide pipe 16 is inserted into the permeable hole 5. The use of the filter cloth 15 to wrap the permeable flower pipe 14 can effectively prevent mud and sand from clogging the seepage hole on the flower pipe and ensure the drainage effect. After the water inside the slope 1 seeps into the backfill area, the water flows into the open channel drainage ditch 13 through the permeable flower pipe 14 and the water guide pipe 16, avoiding the long-term accumulation of water on the inside of the retaining wall.

[0017] In the specific implementation process, a diversion ditch is constructed along the slope direction on the concrete slope 11. The surface runoff on the upper part of the slope 1 can flow quickly into the water-blocking ditch 12 through the diversion ditch and be discharged through the water-blocking ditch 12, which can effectively reduce the scouring of the vertical retaining wall 4 by the surface runoff.

[0018] In the specific implementation process, a stepped gabion mesh 17 is constructed on the side of the slope 1 near the wall foundation 3. The gabion mesh 17 is filled with crushed stone. A diagonal tie bar 18 is set between the wall foundation 3 and the gabion mesh 17. One end of the diagonal tie bar 18 is anchored in the wall foundation 3, and the other end is inserted into the gabion mesh 17 and welded with a cross-shaped limiting block. The gabion mesh 17 arranged in a stepped manner plays a role in squeezing and supporting the slope 1 toe, which can improve the overall stability of the slope 1 support. The gabion mesh 17 and the wall foundation 3 are strengthened by the diagonal tie bar 18, which can further play a role in pressing down the slope and improving the anti-slip performance of the wall foundation 3.
