Description

Technical Field

[0001] This utility model relates to the field of slope protection, and more particularly to a protective structure for slopes in water conservancy and hydropower projects. Background Technology

[0002] In the field of water conservancy and hydropower engineering, the stability and safety of slopes play a decisive role in the long-term stable operation of the project, the safety of surrounding personnel, and the protection of the ecological environment. Water conservancy and hydropower projects are mostly located in mountainous areas with complex terrain. Slopes are affected by topography, geological conditions, and natural factors such as heavy rainfall and earthquakes, resulting in a high risk of geological disasters such as landslides and collapses. At the same time, as the project operates, the impact of human activities and mechanical operations on slope stability gradually increases.

[0003] Traditional slope protection methods have revealed a series of problems in practical applications. Regarding personnel safety, some protective facilities have simple structures that cannot effectively prevent people from accidentally approaching the slope, leading to frequent falls. In terms of slope stability, some protective structures cannot adapt well to complex terrain, and the slope segmentation and reinforcement effects are inadequate. When encountering heavy rainfall or changes in geological conditions, they are highly susceptible to landslides and other geological disasters, causing serious economic losses. Some protective structures do not consider water accumulation, and accumulated water cannot be drained in time, seeping into the slope soil, reducing soil strength and increasing the risk of slope instability. Regarding debris management, there is a lack of effective garbage collection and protection measures. Debris sliding down the slope not only affects the aesthetics of the project area but may also block the drainage system, further threatening slope stability. Furthermore, when the slope is subjected to external impacts, traditional protective structures lack effective buffering mechanisms, failing to absorb and disperse impact forces, easily leading to damage to the protective structure and reducing its protective effect. Utility Model Content

[0004] The purpose of this utility model is to provide a protective structure for slopes in water conservancy and hydropower projects to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a slope in a water conservancy and hydropower project, comprising a slope, a main guardrail at the top of the slope, several concrete partitions on the slope surface, steps on one side of each concrete partition, a garbage collection structure at the bottom of the slope, an anti-collision net on the side of the garbage collection structure away from the concrete partitions, and a tension buffer structure between the anti-collision net and the main guardrail.

[0006] As a preferred embodiment of this utility model, the main guardrail includes a pair of support posts, with a support foot on the side of the support post away from the anti-collision net, soil nails at the bottom between the support post and the support foot, a backing rail at the top between the pair of support posts, and an arc-shaped guardrail below the backing rail.

[0007] As a preferred embodiment of this utility model, the concrete partition is provided with several diamond-shaped planting holes, and the diamond-shaped planting holes are provided with diamond-shaped protective frames.

[0008] As a preferred embodiment of this invention, a drainage groove is provided between the step and the concrete partition.

[0009] As a preferred embodiment of the present invention, the anti-collision protective net includes a support connector, a pair of rotating rods are movably provided on the support connectors, a pair of support rods are provided on the rotating rods, and a net body is provided between the pair of support rods.

[0010] In a preferred embodiment of this utility model, the tensile buffer structure includes a first hinge block and a second hinge block. The first hinge block is mounted on a support rod, and the second hinge block is mounted on a support column. A buffer cylinder is mounted on the first hinge block, and a limiting cylinder is mounted at the other end of the buffer cylinder. A limiting cavity is provided inside the limiting cylinder. A movable rod is mounted on the second hinge block, and a limiting block is mounted on the movable rod. A buffer cavity is provided inside the buffer cylinder, and the movable rod passes through the limiting cylinder and extends into the buffer cavity. A buffer spring is installed inside the buffer cavity, with one end connected to the buffer cavity and the other end connected to the top of the movable rod. The limiting block is movably disposed within the limiting cavity.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] 1. The main guardrail restricts people from approaching the edge of the slope at will, effectively preventing accidental falls and ensuring personnel safety. At the same time, its stable structure can withstand external impacts, protecting the top of the slope and marking the boundary.

[0013] 2. By arranging concrete partitions on the slope surface and setting diamond-shaped planting holes and diamond-shaped protective frames on them, and setting steps and drainage channels on one side of the concrete partitions, the slope surface is effectively divided, reducing the risk of overall slope slippage and enhancing slope stability. At the same time, the soil is reinforced by plant roots to prevent soil loss in the planting holes and avoid landslides and other disasters caused by reduced soil strength. The drainage channels opened between the steps and the concrete partitions achieve the function of drainage and prevent the strength from being reduced due to water accumulation.

[0014] 3. The garbage collection structure enables the collection of debris and garbage sliding down the slope, preventing them from accumulating and affecting the slope stability or blocking the surrounding drainage system, and also preventing garbage from scattering randomly, making it easier to clean up in a centralized manner.

[0015] 4. By setting a tension buffer structure between the support rod of the crash protection net and the support column of the main guardrail, when the crash protection net is impacted, the movable rod moves in the buffer cavity of the buffer cylinder to stretch the buffer spring to absorb the impact energy. At the same time, the limiting cylinder and the limiting block limit the movement range of the movable rod, ensuring that the tension buffer structure works within a reasonable range and maintaining the stability of the entire protection system.

[0026] like Figure 3 , Figure 6 As shown, the main guardrail 2 includes a pair of support posts 201. The side of the support post 201 away from the anti-collision net 7 is provided with a support foot 202. The bottom between the support post 201 and the support foot 202 is provided with soil nails 203. The top between the pair of support posts 201 is provided with a leaning railing 204. The bottom of the leaning railing 204 is provided with an arc-shaped guardrail 205.

[0027] like Figure 4 As shown, the concrete partition 3 has several diamond-shaped planting holes 301, and the diamond-shaped planting holes 301 are provided with diamond-shaped protective frames 302.

[0028] like Figure 2 As shown, a drainage channel 5 is provided between the step 4 and the concrete partition 3.

[0029] like Figure 3 , Figure 4 As shown, the waste collection structure 6 includes a collection platform 601. One side of the collection platform 601 is fitted with a concrete partition 3. A pair of square columns 602 are provided on the collection platform 601, and a collection net 603 is provided between the pair of square columns 602.

[0030] like Figures 3-5 As shown, the anti-collision net 7 includes a support connector 701, a pair of rotating rods 702 are movably mounted on the pair of support connectors 701, a pair of support rods 703 are mounted on the rotating rods 702, and a net body 704 is provided between the pair of support rods 703.

[0031] like Figure 3 , Figure 5 , Figure 7As shown, the tension buffer structure 8 includes a first hinge block 801 and a second hinge block 802. The first hinge block 801 is mounted on the support rod 703, and the second hinge block 802 is mounted on the support column 201. The first hinge block 801 is equipped with a buffer cylinder 803, and the other end of the buffer cylinder 803 is equipped with a limiting cylinder 804. The limiting cylinder 804 has a limiting cavity 805 inside. The second hinge block 802 is equipped with a movable rod 806, and the movable rod 806 is equipped with a limiting block 807. The buffer cylinder 803 has a buffer cavity 808 inside. The movable rod 806 passes through the limiting cylinder 804 and extends into the buffer cavity 808. A buffer spring 809 is installed in the buffer cavity 808. One end of the buffer spring 809 is connected to the buffer cavity 808, and the other end is connected to the top of the movable rod 806. The limiting block 807 is movably disposed in the limiting cavity 805.

[0032] In practice, the main guardrail at the top of slope 1 consists of a pair of support posts 201. Support feet 202 are provided on the side of the support posts 201 furthest from the crash barrier 7, and both are reinforced at the bottom with soil nails 203. A leaning railing 204 is provided at the top of the support posts 201, and an arc-shaped guardrail 205 is provided below. The main guardrail restricts personnel from approaching the edge of slope 1, preventing accidental falls and ensuring personnel safety. Its stable structural design can withstand a certain amount of external impact, serving as protection and boundary marker for the top of slope 1.

[0033] The concrete partitions 3 distributed on the slope 1 effectively divide the slope surface, reducing the risk of overall slope slippage and enhancing the stability of slope 1. The diamond-shaped planting holes 301 on the concrete partitions 3 provide space for plant growth; the plant roots reinforce the soil, further improving the stability of slope 1. The diamond-shaped protective frames 302 prevent soil loss from the planting holes. Steps 4 on one side of the concrete partitions 3 facilitate personnel access to and from slope 1, meeting the needs of inspection and maintenance. The drainage channel 5 between the steps 4 and the concrete partitions 3 collects and drains accumulated water from slope 1 in a timely manner, preventing water from seeping into the soil and causing soil strength reduction, which could lead to landslides and other disasters.

[0034] The waste collection structure 6 at the bottom of slope 1 consists of a collection platform 601, a pair of square columns 602, and a collection net 603. One side of the collection platform 601 is connected to a concrete partition 3 to collect debris and waste sliding down slope 1, preventing its accumulation from affecting the aesthetics of slope 1 or blocking the surrounding drainage system. The collection net 603 prevents waste from scattering randomly, facilitating centralized cleanup.

[0035] The anti-collision protective net 7 consists of a support connector 701, a rotating rod 702, a support rod 703, and a net body 704. When an object impacts the slope 1, the net body 704 can act as a barrier, while the rotating rod 702 and support rod 703 can rotate flexibly and adjust their angles, effectively buffering the impact force and reducing the damage to the slope 1 and the protective structure.

[0036] The anti-collision net 7 has a tension buffer structure 8 between its support rod 703 and the main guardrail support post 201. When the anti-collision net 7 is impacted, the movable rod 806 moves within the buffer cavity 808 of the buffer cylinder 803, compressing the buffer spring 809 to absorb the impact energy. The limiting cylinder 804 and the limiting block 807 restrict the movement range of the movable rod 806, ensuring that the tension buffer structure 8 functions within a reasonable working range and maintaining the stability of the entire protection system.
