Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically a slope protection device with an anti-erosion structure. Background Technology

[0002] Slope protection refers to the measures taken to support, reinforce, and protect slopes to ensure their safety and the safety of their environment. These measures can effectively prevent disasters such as landslides and debris flows.

[0003] Most current slope protection methods are similar in their overall construction, typically using anchor bolts and metal mesh to construct the base, followed by concrete to build the slope surface, which is then reinforced to form support. However, in practical use, there are some functional shortcomings and room for improvement. For example, the slope support generally fits snugly against the slope surface, with less protection for the top of the slope. During heavy rainfall, rainwater seeps down from the top of the slope, increasing the water content of the soil and its overall weight, thus increasing the load on the support. Furthermore, prolonged erosion can easily cause gaps between the support mesh and the slope surface, which will affect the stability of the support in the long run. It also lacks the function of providing graded protection against erosion at the top of the slope.

[0004] Now, a novel slope protection device with an anti-erosion structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a slope support device with an anti-scour structure to solve the problem mentioned in the background art of not having the function of graded anti-scour protection at the top of the slope.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slope support device with an anti-scour structure, comprising multiple sets of longitudinal anchors and transverse anchors, with wire mesh bound and fixed between the longitudinal and transverse anchors, and reinforcing mesh bound and fixed to the outer side of the wire mesh. Multiple sets of concrete slope panels are fixedly connected to the outer side of the reinforcing mesh, with straight water-blocking strips fixedly connected to the front and rear ends of the outer side of the concrete slope panels, and two sets of curved water-blocking strips fixedly connected to the outer side of the concrete slope panels. Multiple planting openings are provided inside the concrete slope panels, and a buffer water-guiding component that can mitigate scour by heavy rainfall is provided at the top of the reinforcing mesh.

[0007] The buffer water guiding assembly includes multiple sets of flat water guiding plates, which are fixedly connected to the top of the steel mesh. A slope water guiding plate is fixedly connected to the right side of the flat water guiding plate. Multiple sets of V-shaped grooves are opened at the top of the flat water guiding plate and the slope water guiding plate. Two sets of anchor bolt holes are opened at the top of the flat water guiding plate.

[0008] As a further technical solution of this utility model, the concrete slope panel and the slope guide plate have the same slope, and the concrete slope panel and the slope guide plate are fixedly connected.

[0009] As a further technical solution of this utility model, the inner diameter of the anchor bolt hole is adapted to the outer diameter of the longitudinal anchor bolt, and the anchor bolt holes are symmetrically distributed about the vertical center line of the flat water guide plate.

[0010] As a further technical solution of this utility model, the longitudinal anchor rod and the transverse anchor rod are filled with concrete grout, the longitudinal anchor rod and the transverse anchor rod have the same outer diameter, and the longitudinal anchor rod, the transverse anchor rod and the steel mesh are fixedly connected.

[0011] As a further technical solution of this utility model, an internally threaded fixing ring is welded to the left side of the transverse anchor rod, and the bottom end of the outer side of the longitudinal anchor rod is threaded. The longitudinal anchor rod passes through the interior of the internally threaded fixing ring, and the threads on the outside of the longitudinal anchor rod and the threads inside the internally threaded fixing ring are matched.

[0012] As a further technical solution of this utility model, an inner steel pipe is vertically arranged inside the longitudinal anchor rod. A grouting port is fixedly connected to the top of the inner steel pipe. A one-way valve is installed at the bottom inside the inner steel pipe. Multiple sets of grout outlet holes are opened at the bottom outside the one-way valve. A pointed cone head is welded to the bottom of the inner steel pipe. The bottom of the inner steel pipe is lower than the bottom of the longitudinal anchor rod. The vertical center lines of the longitudinal anchor rod, the inner steel pipe, and the pointed cone head coincide.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the slope support device with anti-scour structure not only realizes the function of graded anti-scour protection of the slope top, but also realizes the function of increasing strength through anchor connection, and also realizes the function of improving stability through grouting and splitting.

[0014] (1) By setting up flat water guide plates, slope water guide plates, V-shaped grooves and anchor bolt holes, when in use, the slope surface is modified into a multi-level slope surface, and multiple sets of horizontal and vertical anchor holes are opened on the slope. The longitudinal anchor bolts and horizontal anchor bolts are inserted along the anchor holes. The gap between the anchor holes and the anchor bolts is filled by grouting. Then, steel wire mesh and steel mesh are tied on the slope surface, and the steel reinforcement skeleton of the concrete slope panel is tied on the steel mesh. The concrete is then poured to form the structure. At the top of the slope and the steps of the slope surface, the water guide plates formed by the flat water guide plates and slope water guide plates can protect the top of the slope. The rainwater is guided to the concrete slope panel through the V-shaped groove. After passing through the straight water blocking strip and the curved water blocking strip, the flat water guide plate can block the gap between the top of the slope and the steel wire mesh and steel mesh, avoiding separation caused by scouring. The function of graded anti-scouring of the top of the slope is realized.

[0015] (2) By setting longitudinal anchors, transverse anchors and internal threaded fixing rings, when in use, the longitudinal anchors and transverse anchors are inserted along the anchor holes, the longitudinal anchors are inserted into the internal threaded fixing rings at the ends of the transverse anchors and locked by the threads, the longitudinal anchors, transverse anchors and wire mesh and steel mesh form a right triangle, which increases stability and firmness and realizes the function of increasing the strength of the anchor connection;

[0016] (3) By setting an inner steel pipe, grouting port, one-way valve, grout outlet and pointed cone, when in use, as the longitudinal anchor rod and the transverse anchor rod are inserted into the anchor hole, the grouting pump is connected to the grouting port at the top of the inner steel pipe and the concrete grout is continuously injected. The concrete grout goes down along the inner steel pipe and overflows from the grout outlet, splitting the soil layer below. When the concrete grout solidifies, it can form a tree-like concrete component, further increasing stability and realizing the function of grouting splitting to improve stability.

[0023] Example: Please refer to Figure 1-4A slope protection device with an anti-scour structure includes multiple sets of longitudinal anchors 1 and transverse anchors 2. A wire mesh 3 is tied and fixed between the longitudinal anchors 1 and the transverse anchors 2. A reinforcing mesh 4 is tied and fixed to the outer side of the wire mesh 3. Multiple sets of concrete slope panels 5 are fixedly connected to the outer side of the reinforcing mesh 4. Straight water-blocking strips 6 are fixedly connected to the front and rear ends of the outer side of the concrete slope panel 5. Two sets of curved water-blocking strips 7 are fixedly connected to the outer side of the concrete slope panel 5. Multiple planting openings 8 are opened inside the concrete slope panel 5. A buffer water-guiding component that can alleviate the scour of heavy rainfall is set at the top of the reinforcing mesh 4.

[0024] Please see Figure 1-4 A slope support device with an anti-scour structure also includes a buffer water guiding component. The buffer water guiding component includes multiple sets of flat water guiding plates 9, which are fixedly connected to the top of the steel mesh 4. A slope water guiding plate 10 is fixedly connected to the right side of the flat water guiding plate 9. Multiple sets of V-shaped grooves 11 are opened at the top of the flat water guiding plate 9 and the slope water guiding plate 10. Two sets of anchor bolt holes 12 are opened at the top of the flat water guiding plate 9.

[0025] The concrete slope panel 5 and the slope guide plate 10 have the same slope. The concrete slope panel 5 and the slope guide plate 10 are fixedly connected. The inner diameter of the anchor bolt hole 12 is matched with the outer diameter of the longitudinal anchor bolt 1. The anchor bolt hole 12 is symmetrically distributed about the vertical center line of the flat guide plate 9. The longitudinal anchor bolt 1 and the transverse anchor bolt 2 are filled with concrete grout. The outer diameter of the longitudinal anchor bolt 1 and the transverse anchor bolt 2 are the same. The longitudinal anchor bolt 1, the transverse anchor bolt 2 and the steel mesh 4 are fixedly connected. The water guiding capacity is improved by grading and top shielding.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the water guide plate composed of the flat water guide plate 9 and the slope water guide plate 10 can protect the top of the slope. The rainwater is guided to the concrete slope panel 5 through the V-shaped groove 11 and discharged through the straight water blocking strip 6 and the curved water blocking strip 7. The flat water guide plate 9 can block the gap between the top of the slope and the wire mesh 3 and the steel mesh 4 to avoid separation caused by erosion.

[0027] The left side of the transverse anchor 2 is welded with an internal threaded fixing ring 13, and the bottom of the outer side of the longitudinal anchor 1 is threaded. The longitudinal anchor 1 passes through the interior of the internal threaded fixing ring 13. The threads on the outside of the longitudinal anchor 1 and the threads inside the internal threaded fixing ring 13 match. The connection between the transverse and longitudinal anchors strengthens and improves the strength and stability.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the longitudinal anchor 1 is inserted into the internal threaded fixing ring 13 at the end of the transverse anchor 2 and locked by the thread. The longitudinal anchor 1, the transverse anchor 2, the wire mesh 3, and the reinforcing mesh 4 form a right triangle, which increases stability and firmness.

[0029] The longitudinal anchor rod 1 has an inner steel pipe 14 vertically installed inside. The top of the inner steel pipe 14 is fixedly connected to a grouting port 15. A one-way valve 16 is installed at the bottom inside the inner steel pipe 14. Multiple sets of grout outlet holes 17 are opened at the bottom outside the one-way valve 16. A pointed cone head 18 is welded to the bottom of the inner steel pipe 14. The bottom of the inner steel pipe 14 is lower than the bottom of the longitudinal anchor rod 1. The vertical center lines of the longitudinal anchor rod 1, the inner steel pipe 14, and the pointed cone head 18 coincide. The stability is further increased by grouting and splitting.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, the grouting pump is connected to the grouting port 15 at the top of the inner steel pipe 14 and concrete grout is continuously injected. The concrete grout flows down along the inner steel pipe 14 and overflows from the grout outlet 17, splitting the soil layer below. Once the concrete grout solidifies, it forms a tree-like concrete component, further increasing stability.

[0031] Working principle: When using this utility model, firstly, the slope is modified into a multi-level slope, and multiple sets of horizontal and vertical anchor holes are opened on the slope. The longitudinal anchor rods 1 and the horizontal anchor rods 2 are inserted along the anchor holes. The gaps between the anchor holes and the anchor rods are filled by grouting. Then, wire mesh 3 and steel mesh 4 are tied and constructed on the slope. The steel reinforcement skeleton of the concrete slope panel 5 is tied to the steel mesh 4 and the concrete is poured to form the structure. At the top of the slope and the steps of the slope, the water guide plate composed of the flat water guide plate 9 and the slope water guide plate 10 can protect the top of the slope. The rainwater is guided to the concrete slope panel 5 through the V-shaped groove 11 and discharged through the straight water-blocking strip 6 and the curved water-blocking strip 7. The flat water guide plate 9 can block the gaps between the top of the slope and the wire mesh 3 and steel mesh 4 to avoid separation caused by erosion. Longitudinal anchor 1 and transverse anchor 2 are inserted along the anchor holes. The longitudinal anchor 1 is inserted into the internal threaded fixing ring 13 at the end of the transverse anchor 2 and locked by the thread. The longitudinal anchor 1, transverse anchor 2, wire mesh 3, and reinforcing mesh 4 form a right-angled triangle, increasing stability and firmness. As the longitudinal anchor 1 and transverse anchor 2 are inserted and installed in place along the anchor holes, the grouting pump is connected to the grouting port 15 at the top of the inner steel pipe 14 and concrete grout is continuously injected. The concrete grout flows down along the inner steel pipe 14 and overflows from the grout outlet 17, splitting the soil layer below. Once the concrete grout solidifies, it forms a tree-like concrete component, further increasing stability.
