Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a slope protection structure for a spoil disposal site. Background Technology

[0002] Spoil disposal sites typically consist of solid waste such as excavated soil, slag, and construction debris generated during construction projects, commonly found in mining, water conservancy projects, and road construction. When the accumulated solid waste in a spoil disposal site reaches a certain quantity, it can easily pose a threat to the surrounding environment, especially in the natural environment. Heavy rains and debris flows are the main factors threatening the stability of spoil disposal site slopes. These natural disasters have strong impact and erosive capabilities, capable of destroying the soil structure of spoil disposal site slopes in a short period of time, leading to slope instability. Especially in mountainous areas or areas with complex geological conditions, heavy rainfall rapidly increases the water content of the slope, reducing the shear strength of the soil, while the impact of debris flows further exacerbates slope erosion and loosening of deep soil. Once a spoil disposal site slope becomes unstable, it will not only cause severe damage to the natural slope but may also trigger a chain reaction, leading to large-scale collapses. The collapsed soil and rocks may directly block roads, disrupt transportation, and even threaten the lives and property of nearby residents. In addition, slope instability at spoil disposal sites can also damage the surrounding ecological environment, exacerbate soil erosion, and create a vicious cycle.

[0003] Therefore, in view of this, the inventors proposed a slope protection structure for spoil disposal sites to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a slope protection structure for spoil disposal sites to solve the problem that traditional spoil disposal site slopes are easily affected by heavy rain or debris flow, leading to slope instability and collapse.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A slope protection structure for a spoil disposal site includes slope support components and roadbed support components. The number of slope support components is at least one. The slope support components are laid on the slope surface, and the roadbed support components are located at the bottom of the slope support components.

[0007] The slope support component includes a first anchor, a protective component, and a vegetation component. The vegetation component is installed at intervals on the slope surface. The first anchor is set perpendicular to the slope surface, with one end of the first anchor extending into the slope and the other end of the first anchor connected to the protective component.

[0008] Furthermore, when there are two or more slope protection components, a buffer platform is provided between adjacent slope protection components, and a first intercepting ditch is provided on the buffer platform.

[0009] Furthermore, the first anchor includes a plurality of anchor rods, which are spaced apart along the slope surface, and the length of each anchor rod increases sequentially from bottom to top along the slope surface.

[0010] Furthermore, the anchor rod includes a rod body and a bracket, and there are multiple brackets, with each bracket arranged at intervals along the length direction of the rod body.

[0011] Furthermore, the vegetation component includes a vegetation board and a vegetation substrate. There are multiple vegetation boards, and each vegetation board is evenly installed on the slope surface. The vegetation substrate is filled between adjacent vegetation boards.

[0012] Furthermore, the roadbed support component is a first roadbed base, which includes a first base and a second anchor. The first base is installed obliquely at the bottom of the slope support component. There are multiple second anchors, which are spaced apart. One end of each second anchor is connected to the first base, and the other end of the second anchor extends into the slope.

[0013] Furthermore, the first base includes a plurality of first reinforcing bars and a plurality of second reinforcing bars, which are arranged alternately to form a reinforcing mesh. The first base, with its alternating arrangement of multiple first and second reinforcing bars forming a reinforcing mesh, enhances the overall strength and stability of the first base, providing reliable foundation support for slope protection.

[0014] Furthermore, the roadbed support component is a second roadbed base, which includes a second base, a steel column, and a third anchor. The steel column is fixedly installed at the bottom of the second base. There are multiple third anchors, which are spaced apart. One end of each third anchor is connected to the second base, and the other end of each third anchor extends into the slope.

[0015] Furthermore, the space between the second base and the slope surface is filled with gravel, and the top and bottom of the gravel are covered with mortar.

[0016] According to the above technical solution, the crushed stone layer can effectively enhance drainage performance, while the mortar plays a role in bonding and seepage prevention, preventing the loss of crushed stone. This design improves the stability and erosion resistance of the structure and is suitable for slope reinforcement under complex spoil heap geological conditions.

[0017] Furthermore, a slope bottom structure is provided below the roadbed support component. The slope bottom structure includes a roadbed structure layer and a pavement structure layer, and a second intercepting ditch is provided on the roadbed structure layer.

[0018] According to the above technical solution, a second intercepting ditch is opened on the roadbed structure layer to collect and guide slope runoff, prevent water accumulation from affecting the stability of the roadbed and slope, and ensure the safety and durability of the overall slope protection system.

[0019] The beneficial effects of this utility model are:

[0020] This utility model discloses a slope protection component comprising a first anchor, a protective component, and a vegetation component. The first anchor is installed perpendicular to the slope surface, with one end extending into the slope to enhance anchoring force, and the other end connected to the protective component to form a stable support system. The vegetation component is installed intermittently on the slope surface. Through the combination of vegetation boards and vegetation substrate, it protects the slope surface from erosion and promotes vegetation restoration, enhancing ecological benefits. The roadbed support component is located at the bottom of the slope protection component to further reinforce the slope foundation and prevent slope slippage. When there are multiple slope protection components, buffer platforms and intercepting ditches are set between adjacent components to effectively disperse water flow impact and drain water, reducing rainwater erosion of the slope. The overall structure, through the comprehensive design of anchoring, protection, vegetation restoration, and drainage systems, significantly improves the disaster resistance of the spoil heap slope, ensuring project safety and sustainable development of the ecological environment.

Detailed Implementation

[0031] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] This embodiment proposes a slope protection structure for a spoil heap, such as... Figures 1 to 8 As shown, it includes a slope protection component 1 and a roadbed protection component 2. The number of slope protection components 1 is at least one, and the slope protection component 1 is laid on the slope surface. The roadbed protection component 2 is set at the bottom of the slope protection component 1. Preferably, the number of slope protection components 1 is two, both located above the roadbed protection component 2.

[0034] like Figure 1 , Figure 4 and Figure 7As shown, the slope support component 1 includes a first anchor 11, a protective component 12, and a vegetation component 13. The vegetation components 13 are installed at intervals on the slope surface. The first anchor 11 is set perpendicular to the slope surface, with one end of the first anchor 11 extending into the slope and the other end of the first anchor 11 connected to the protective component 12. Preferably, the protective component 12 in this embodiment is a protective net.

[0035] As a preferred embodiment, such as Figure 1 and Figure 4 As shown, when there are two or more slope support components 1, a buffer platform 3 is set between adjacent slope support components 1, and a first intercepting ditch 31 is opened on the buffer platform 3. By opening the first intercepting ditch 31 on the buffer platform 3, the first intercepting ditch 31 effectively collects and guides the slope runoff, prevents water accumulation from affecting the slope, and enhances the overall stability and erosion resistance of the slope to a certain extent by diverting and draining the water.

[0036] As a preferred embodiment, such as Figure 1 and Figure 4 As shown, the first anchor 11 includes several anchor rods, which are spaced apart along the slope surface. The length of each anchor rod increases sequentially from bottom to top along the slope surface. This design can provide gradually increasing anchoring force according to the stress characteristics of different slope heights. The shorter anchor rods at the bottom are mainly used for surface reinforcement, while the longer anchor rods at the top penetrate deep into the slope to enhance overall stability.

[0037] As a preferred embodiment, such as Figure 6 and Figure 7 As shown, the anchor rod includes a rod body 111 and a bracket 112. There are multiple brackets 112, and each bracket 112 is arranged at intervals along the length of the rod body 111. When installing the anchor rod, it is necessary to first drill holes in the slope to form anchor holes 113. After drilling, the brackets 112 are installed on the rod body 111. Then, the rod body 111 and the brackets 112 are inserted into the anchor holes 113. Finally, high-pressure grouting or concrete is poured into the anchor holes 113. The purpose of setting the brackets 112 is to improve the tensile strength of the rod body 111 in the anchor holes 113, so that the rod body 111 is firmly embedded in the anchor holes 113.

[0038] As a preferred embodiment, such as Figure 7As shown, the vegetation component 13 includes a vegetation board 131 and a vegetation substrate 132. There are multiple vegetation boards 131, and each vegetation board 131 is evenly installed on the slope surface. The vegetation substrate 132 fills the spaces between adjacent vegetation boards 131. The vegetation substrate 132 is made of organic soil or fibrous soil. The vegetation board 131 provides a stable growth base for the vegetation and prevents soil erosion on the slope surface, while the vegetation substrate 132 provides a rooting and growth environment for the plants, thereby enhancing the slope's resistance to erosion. The vegetation cover and root system have a soil-fixing effect, effectively protecting the slope surface and reducing soil erosion.

[0039] Example 1

[0040] The roadbed support component 2 is a first roadbed 21, which includes a first base 211 and second anchors 212. The first base 211 is installed at an angle at the bottom of the slope support component 1. Multiple second anchors 212 are spaced apart, with one end connected to the first base 211 and the other end extending inwards into the slope. The first base 211, located at the bottom of the slope support component 1, provides basic support, while the second anchors 212, with one end connected to the first base 211 and the other end extending inwards into the slope, further enhance the anchoring effect. Through the inclined design and the distribution of multiple anchor points, the first roadbed 21 can effectively disperse slope stress, prevent slope slippage, and improve overall stability. This structure is suitable for reinforcing the bottom of slopes in low and relatively loose spoil heaps, ensuring a tight bond between the support system and the slope, and enhancing anti-sliding and shear resistance.

[0041] Preferably, the first base 211 includes a plurality of first reinforcing bars 2111 and a plurality of second reinforcing bars 2112. The first reinforcing bars 2111 and the second reinforcing bars 2112 are arranged in an alternating manner to form a reinforcing mesh. In this embodiment, the reinforcing mesh and concrete are cured to form the first base 211. The reinforcing mesh is used to enhance the overall strength and stability of the first base 211 and provide reliable foundation support for slope protection.

[0042] Example 2

[0043] The roadbed support component 2 is a second roadbed base 22, which includes a second base 221, reinforcing bars 222, and third anchors 223. The reinforcing bars 222 are fixedly installed at the bottom of the second base 221. Multiple third anchors 223 are spaced apart, with one end connected to the second base 221 and the other end extending inwards into the slope. The reinforcing bars 222, fixed to the bottom of the second base 221, provide vertical support, while the third anchors 223, connected at one end to the second base 221 and extending inwards into the slope, enhance the anchoring effect. Through the synergistic effect of the reinforcing bars 222 and the third anchors 223, the second roadbed base 22 is designed to effectively disperse slope stress, prevent slope slippage, and improve overall stability. Compared to Embodiment 1, this embodiment is suitable for slopes with high gradients in spoil heaps, ensuring a tight bond between the support system and the slope.

[0044] In this application, it is preferred that the structures of the second anchor 212 and the third anchor 223 are the same as those of the first anchor 11.

[0046] As a preferred option, such as Figure 5 As shown, the space between the second base 221 and the slope surface is filled with crushed stone 4, and mortar 5 is provided at the top and bottom of the crushed stone 4; the crushed stone 4 can effectively enhance the drainage performance, while the mortar 5 plays a role in bonding and seepage prevention.

[0047] As a preferred embodiment, such as Figure 5 As shown, a slope bottom structure 6 is provided below the roadbed support component 2. The slope bottom structure 6 includes a roadbed structure layer 61 and a pavement structure layer 62. A second intercepting ditch 611 is provided on the roadbed structure layer 61. By providing a second intercepting ditch 611 on the roadbed structure layer 61, the slope runoff is collected and guided, preventing water accumulation from affecting the roadbed structure layer 61 and ensuring the safety and durability of the overall slope protection system.

[0048] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
