Description

Technical Field

[0001] The utility model relates to the technical field of slope treatment, in particular to a slope care structure. Background Art

[0002] Slope stability is one of the key issues in the field of engineering geology, especially in water conservancy, hydropower, and transportation projects, where its stability often becomes the key to engineering construction and safe operation. The traditional design solution is to remove all the covering layers on the slope surface until a stable rock slope is exposed. If the rock is relatively broken, reinforcement measures such as spray anchor support are required to ensure slope stability. Alternatively, support measures such as anti-slip piles, anchor frame beams and other strong support measures can be used. Combined with Figure 1 Most existing drainage structures for slope A directly insert drainage pipe A1 into the drainage hole of slope A. When rainfall suddenly increases in extreme weather, the water flow in the mountain will cause great pressure on slope A. However, drainage pipe A1 inserted on slope A can only take in water at the end, and the drainage area is small. Therefore, water can easily flow out from the cracks in the slope, resulting in a high risk of landslide. Utility Model Content

[0003] The utility model discloses a slope care structure, which aims to improve the problems of small drainage area and high landslide risk of existing slope structures.

[0004] The utility model adopts the following scheme:

[0005] A slope care structure includes a slope and a drainage component arranged along the slope of a mountain, wherein a plurality of first drainage pipes are evenly inserted on the slope, and the drainage component includes a second drainage pipe and a plurality of drainage pipes, wherein the second drainage pipe is located at the top of the slope and is arranged along the extension direction of the slope, and water inlets are provided on the ends and side walls of the drainage pipes, and each of the drainage pipes is arranged to be distributed vertically and horizontally along the slope of the mountain to form a grid-like drainage channel, and the ends of each drainage pipe distributed longitudinally are connected to the second drainage pipe, so that after the water flows into the second drainage pipe from the drainage channel, it flows into the drainage ditch or collection pool along the second drainage pipe.

[0006] As a further improvement, the drainage pipe includes a plurality of S-shaped plates, the outer periphery of the drainage pipe is wrapped with a geotextile layer, and a crushed stone layer is laid on the outer periphery of the geotextile layer.

[0007] As a further improvement, water inlets are provided on both sides of the S-shaped plate along its length.

[0008] As a further improvement, the structure of the second drain pipe is the same as that of the drainage pipe.

[0009] As a further improvement, the distance between two adjacent drainage tubes distributed in the longitudinal direction is not greater than 10 m, and the distance between two adjacent drainage tubes distributed in the transverse direction is not greater than 2 m.

[0010] As a further improvement, the second drain pipe is connected to the drainage pipe via a T-shaped joint, and the two crossed drainage pipes are connected via a cross-shaped joint.

[0011] As a further improvement, the second drainage pipe is a bundled pipe, and the outer sheath diameter of the bundled pipe is not less than 1m.

[0012] As a further improvement, the drainage pipe is buried in a drainage ditch dug along the slope of the mountain and is compacted by a rammed earth layer.

[0013] As a further improvement, one end of the first drainage pipe is exposed on the outer wall of the slope, and the other end is at least partially inserted into the interior of the mountain.

[0014] As a further improvement, a pressure sensor is installed in the second drain pipe to monitor the water flow pressure.

[0015] By adopting the above technical solution, the utility model can achieve the following technical effects:

[0016] 1. By evenly placing several primary drainage pipes along the slope, accumulated water can be drained. Simultaneously, drainage components are deployed along the mountain slope, allowing water to flow into a grid-like drainage channel and into the secondary drainage pipes at the top of the slope. This increases the drainage area, improves drainage efficiency, reduces slope pressure, and provides favorable protection for the slope, thereby reducing the risk of landslides. This structure is also suitable for existing slopes. Deploying drainage components on existing slopes can improve slope protection and prevent landslides.

[0017] 2. The outer periphery of the drainage pipe is wrapped with a geotextile layer, and a gravel layer is laid on the outer periphery of the geotextile layer to prevent particles such as mud and sand from entering the drainage pipe and avoid clogging of the drainage pipe. In addition, the drainage pipe is composed of a number of S-shaped plates stacked together, and each S-shaped plate is provided with water inlets on both sides along its length, so that water flows from all angles can enter the drainage channel, that is, water flows from the end and side of the drainage pipe to further improve the drainage efficiency. The S-shaped plate can be formed by extrusion, and the material is lighter, which can improve construction efficiency. Among them, the S-shaped setting can also improve the side pressure resistance and the overall bearing capacity is strong. The arrangement of the S-shaped plates in the drainage pipe can be arranged in a columnar shape along the circumferential direction, or in a rectangular shape. The S-shaped plates can be fixed by glue or welding. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example

[0030] Combine Figures 1 to 4The present embodiment provides a slope care structure, including a slope 1 and a drainage component arranged along the slope of a mountain 2. Several first drainage pipes 11 are evenly inserted on the slope 1. The drainage component includes a second drainage pipe 31 and several drainage pipes 32, wherein the second drainage pipe 31 is located at the top of the slope 1 and is arranged along the extension direction of the slope 1. Water inlets 322 are provided on the ends and side walls of the drainage pipes 32. Each drainage pipe 32 is arranged to be distributed vertically and horizontally along the slope of the mountain 2 to form a grid-like drainage channel, and the ends of each drainage pipe 32 distributed longitudinally are connected to the second drainage pipe 31, so that after the water flows into the second drainage pipe 31 from the drainage channel, it flows into the drainage ditch or the collection pool along the second drainage pipe 31.

[0031] It should be noted that in this embodiment, by evenly inserting a number of first drainage pipes 11 on the slope 1, the accumulated water at the slope 1 can be drained. At the same time, drainage components are arranged on the slope of the mountain 2, so that the water flow on the slope of the mountain 2 can enter the grid-shaped drainage channel and flow along the drainage channel into the second drainage pipe 31 located at the top of the slope 1, thereby increasing the drainage area, improving drainage efficiency, reducing the pressure on the slope 1, forming a favorable protection for the slope 1, and thus reducing the risk of landslides in the mountain 2. At the same time, this structure is also applicable to the situation where a slope A already exists. By arranging drainage components on the mountain 2 with an existing slope A, the protection quality of the slope A can be improved, and the occurrence of landslides in the mountain 2 can be avoided.

[0032] In a preferred embodiment, the drainage pipe 32 includes a plurality of S-shaped plates 321, the outer periphery of the drainage pipe 32 is wrapped with a geotextile layer 33, and a gravel layer is laid on the outer periphery of the geotextile layer 33, thereby preventing particles such as mud and sand from entering the drainage pipe 32 and avoiding clogging of the drainage pipe 32. Specifically, the drainage pipe 32 is composed of a plurality of S-shaped plates 321 stacked together, and each S-shaped plate 321 is provided with a water inlet 322 on both sides along its length, so that water flows from all angles can enter the drainage channel, that is, water flows from the ends and sides of the drainage pipe 32, thereby further improving drainage efficiency. The S-shaped plates 321 can be formed by extrusion, and the material is relatively light, which can improve construction efficiency. Among them, the S-shaped setting can also improve the side pressure resistance and the overall bearing capacity is strong. The arrangement of the S-shaped plates 321 in the drainage pipe 32 can be arranged in a columnar shape along the circumferential direction, or in a rectangular shape. The S-shaped plates 321 can be fixed by adhesive or welding.

[0033] In one embodiment, the structure of the second drain pipe 31 is identical to that of the drainage pipe 32, facilitating installation. Using the same pipe material, they avoid misplacement. In another embodiment, the second drain pipe 31 is a clustered pipe with an outer sheath diameter of no less than 1 meter. Multiple microtubes are arranged within the outer sheath, reducing noise generated by water impact. Clustered pipes are also low-cost, reducing the overall cost of the care system.

[0034] In an alternative embodiment of the present invention, based on the above-described embodiment, the spacing between two adjacent longitudinally distributed drainage pipes 32 is no greater than 10 meters, and the spacing between two adjacent transversely distributed drainage pipes 32 is no greater than 2 meters. This ensures effective drainage and prevents the problem of low drainage efficiency caused by excessive spacing. Specifically, the second drainage pipe 31 is connected to the drainage pipe 32 via a T-joint, and the two intersecting drainage pipes 32 are connected via a cross-joint. Each joint includes a geotextile, and a crushed stone layer is laid around the periphery of the geotextile.

[0035] Preferably, the drainage pipe 32 is buried in a drainage ditch dug along the slope of the mountain 2 and compacted by a rammed earth layer. In other embodiments, a concrete layer can also be provided on the rammed earth layer to prevent the drainage pipe 32 from being damaged and causing a problem of blocked drainage channels.

[0036] In another embodiment, one end of the first drain pipe 11 is exposed on the outer wall of the slope 1, and the other end is at least partially inserted into the interior of the mountain 2 to ensure the drainage effect. For example, the first drain pipe 11 is inserted into the drainage hole reserved on the slope 1, and a pressure sensor is installed in the second drain pipe 31 to monitor the water flow pressure. The pressure sensor is electrically connected to the control component, which can be a circuit board, a computer or other terminal. The water pressure in the second drain pipe 31 is detected by the pressure sensor, thereby intelligently monitoring the state of the water flow in the mountain 2 to facilitate the adoption of emergency measures. The circuit principle and circuit structure between the control component and the pressure sensor are prior art and will not be repeated here.

[0037] The implementation of the drainage assembly of this embodiment includes the following construction steps:

[0038] 1. Dig a drainage ditch along the slope of the mountain, lay a gravel layer at the bottom, and lay a standard of 300g / m on the gravel layer. 2 Geotextile layer 33;

[0039] 2. Place the drainage tubes 32 and connect them with joints. Wrap the geotextile layer 33 tightly around the drainage tubes 32 and joints, and then lay the top gravel layer.

[0040] 3. Backfill soil on the top gravel layer and tamp it down;

[0041] 4. Dig the installation trench along the top of the slope 1, lay the bottom gravel layer, and lay the standard of 300g / m on the gravel layer. 2 Geotextile;

[0042] 5. Place the second drainage pipe 31, connect the drainage pipe to the drainage pipe 32 with a T-joint, wrap the geotextile tightly, and then lay the top gravel layer;

[0043] 6. Backfill soil on the top gravel layer and tamp it down.

[0044] It should be mentioned that the construction sequence between the drainage pipe 32 and the second drainage pipe 31 can be carried out simultaneously or one after another, without any specific limitation, and can be flexibly adjusted according to the conditions of the construction site.

[0045] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
