Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering, and in particular to an ecological slope protection support structure for water conservancy and hydropower engineering. Background Technology

[0002] With the increasing severity of global climate change and soil erosion, the need for ecological environment protection and sustainable development in water conservancy and hydropower projects is becoming increasingly prominent. Against this backdrop, traditional rigid slope protection structures are gradually revealing their shortcomings in ecological restoration, environmental protection, and long-term stability. Traditional slope protection methods mostly rely on non-biological materials such as reinforced concrete and stone. While these materials can effectively prevent landslides and soil erosion in the short term, they lack ecological restoration capabilities and are prone to causing long-term environmental problems such as soil degradation and vegetation loss.

[0003] To overcome the limitations of traditional rigid slope protection structures, ecological slope protection technology has gradually emerged as a new research direction. Ecological slope protection not only enhances slope stability but also improves soil structure, promotes vegetation growth, and facilitates ecosystem restoration. It strengthens the slope soil through the natural growth of plant roots, achieving the dual goals of soil and water conservation and ecological restoration. However, while existing ecological slope protection systems can address soil erosion and ecological restoration issues to some extent, they still suffer from poor structural stability, complex construction, and difficult maintenance, limiting their widespread application in water conservancy and hydropower projects.

[0004] In existing technologies, some ecological slope protection structures have adopted techniques such as planting vegetation or sprayed vegetation to help reinforce the slope through the growth of plant roots. However, these technologies often fail to fully consider the role of plant growth in the connection and structural reinforcement between the dam and the slope. At the same time, existing vegetation slope protection systems also have problems such as poor water drainage and insufficient dam durability. Many projects use permeable concrete for water permeability, but in reality, the internal channels of permeable concrete are complex and narrow, and they are blocked by scale and other substances after a short period of use. Moreover, traditional slope protection structures are often cast in place, which not only has a high site occupation rate but also leads to low standardization of the entire structure and high maintenance difficulty. Utility Model Content

[0005] This utility model aims to provide an ecological slope protection support structure for water conservancy and hydropower projects. The whole structure adopts semi-prefabricated components, which can be wrapped around the dam body by plant roots to tightly integrate it with the slope. It also has the function of water permeability and return flow, making construction convenient and solving the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An ecological slope protection support structure for water conservancy and hydropower projects includes a dam body, on which a vegetation protection system is provided. Counterweight blocks and prefabricated retaining blocks are connected to both ends of the dam body. The vegetation protection system includes vegetation protection components and truss reinforcement components. The vegetation protection components are used to place vegetation bags and utilize plant roots to grow and wrap around the dam body and the slope of the slope. Multiple truss reinforcement components are spaced apart on the vegetation protection components.

[0008] Furthermore, the vegetation dam protection component includes a vegetation board located above the dam body, with both ends of the vegetation board connected to a counterweight block and a precast retaining block, respectively.

[0009] Furthermore, the vegetation board includes multiple vegetation zones and multiple reinforcement zones. The vegetation zones have multiple vegetation holes for placing vegetation bags. The reinforcement zones are equipped with truss reinforcement components. The dam body has multiple fine channels.

[0010] Furthermore, the truss reinforcement assembly includes two baffles vertically mounted on the vegetation board, a first truss between the two baffles, the first truss being connected to the vegetation board, and a load-bearing rod between the first truss and the baffle below.

[0011] Furthermore, a rope hole is provided through the baffle for threading a rope through it.

[0012] Furthermore, a porous reinforcing strip is connected between the vegetation board and the dam body, and the precast block is provided with multiple return holes that cooperate with the porous reinforcing strip.

[0013] Furthermore, the counterweight has a connecting block at one end and a corresponding connecting groove at the other end; a second truss is provided on the connecting block, and the counterweight has a casting hole that passes through the connecting groove.

[0014] Furthermore, the prefabricated block has a square groove, and a third truss is provided on the bottom surface of the square groove. The two ends of the third truss are respectively provided with inserts and slots, and the inserts and slots are provided with corresponding pin holes.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, through the design of a vegetation-based dam protection system, allows the plant roots in the vegetation bags to grow downwards and pass through and wrap around multiple fine channels, tightly integrating the dam body and the slope. It can effectively reinforce the dam body through the root system structure, consolidate the slope soil, reduce soil erosion, promote ecological restoration, improve soil structure, enhance the slope's resistance to erosion, and improve the ecological value of water conservancy and hydropower projects.

[0017] 2. The truss reinforcement components and porous reinforcement strips give the entire slope protection structure higher resistance to shear, bending and water impact, effectively improving the durability of the structure, especially preventing damage to the dam body caused by water impact and erosion.

[0018] 3. The channels and return holes in the porous reinforcement strip work together to form a return flow path, which helps the water flow to infiltrate and discharge effectively. When the permeability of the fine channels is reduced due to the entanglement of plant roots, auxiliary return drainage can be carried out, thereby reducing the erosion of the dam body by water and improving the permeability and long-term durability of the dam body.

[0019] 4. In this utility model, a force-bearing bar is provided between the first truss and the lower baffle. The force-bearing bar can provide an additional force transmission path, so that the water wave impact force is transmitted from the lower outer baffle to the vegetation board to disperse the load and improve the protection effect, thereby improving the stability between the truss reinforcement component and the vegetation board.

[0020] 5. The slope protection support structure of this utility model is entirely prefabricated, manufactured directly in the factory, ensuring standardized forming, proper curing, and stable quality. It also simplifies and streamlines the construction process, reducing on-site construction time. Furthermore, the maintenance of the planting bags is convenient. While watering is needed before the plant roots penetrate the slope soil, this maintenance process can simultaneously cure the concrete of the truss reinforcement components, simplifying the process and improving efficiency.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] This embodiment provides an ecological slope protection support structure for water conservancy and hydropower projects, such as... Figures 1 to 5As shown, the structure includes a dam body 1, on which a vegetation protection system 2 is installed. Counterweight blocks 11 and precast retaining blocks 12 are connected to both ends of the dam body, respectively. Both counterweight blocks 11 and precast retaining blocks 12 are equipped with truss connection mechanisms. The vegetation protection system 2 includes a vegetation protection component 21 and a truss reinforcement component 22. The vegetation protection component 21 is used to place vegetation bags 3, allowing plant roots to grow and wrap around the dam body 1 and the slope. The truss reinforcement component 22 can be maintained simultaneously during plant maintenance. The ecological slope protection support structure is a precast concrete component. By setting the vegetation protection system 2 on the dam body 1, the plants in the vegetation bags 3 can extend their roots to pass through and wrap around the dam body 1, forming a tight bond with the slope, improving the stability of the dam body 1. The roots can also improve the soil looseness of the slope. The truss reinforcement component 22, as a precast template, enhances the load-bearing capacity of the entire structure after concrete pouring, making the slope protection structure more stable and effectively improving the durability of the slope protection project, including shear resistance and erosion resistance. During the initial growth stage of the plants in the planting bags 3, when watering and maintaining the plants, the water may splash or seep onto the cast-in-place concrete of the truss reinforcement component 22, thus curing it. Generally, after the concrete of the truss reinforcement component 22 reaches 3 days of strength, the planting bags 3 can be placed in the planting dam component 21 for plant maintenance. Subsequently, when watering and maintaining the plants, the cast-in-place concrete on the truss reinforcement component 22 can be cured to 28 days of strength.

[0032] Specifically, the counterweight 11 has multiple anchor holes for driving in bolts for initial anchoring; the precast block 12 has a pile at its bottom for embedding in pre-drilled pile holes to improve the overall stability of the structure.

[0033] Furthermore, the vegetation dam protection component 21 includes a vegetation board 211, which is horizontally positioned above the dam body 1, with its two ends connected to a counterweight block 11 and a prefabricated stop block 12, respectively. The vegetation board 211 includes multiple vegetation zones 212 and multiple reinforcement zones 213, which are staggered. The vegetation zones 212 have multiple vegetation holes 2121 for placing vegetation bags 3. The dam body 1 has multiple fine channels 13. The reinforcement zones 213 are equipped with truss reinforcement components 22. The vegetation board 211 helps to distribute external loads and provides vegetation holes 2121 for placing vegetation bags 3. By staggering the vegetation zones 212 and reinforcement zones 213, plant growth and structural reinforcement are effectively combined. The planting bags 3 are placed inside the planting holes 2121 and positioned above the dam body 1. After the planting bags 3 grow, their roots extend through the multiple pores 13 of the dam body 1 and penetrate into the soil, thus wrapping around the dam body 1 and the slope, reinforcing the soil of the slope, promoting soil consolidation, and enhancing the ecological restoration effect of the slope protection. At the same time, the pores 13 also facilitate water infiltration and drainage, thereby improving the durability of the dam body 1.

[0034] Furthermore, the truss reinforcement component 22 includes two baffles 221 vertically mounted on the vegetation board 211, with a first truss 222 between the two baffles 221. The first truss 222 is connected to the vegetation board 211 and includes a load-bearing rod 2221 vertically connected to the lower baffle 221. A channel is formed between the two prefabricated baffles 221. After multiple ecological slope protection support structures are spliced, sealant is applied and the outer side is blocked by another template before concrete pouring. The first truss 222 improves the tightness of the bond between the cast-in-place concrete and the prefabricated vegetation board 211 and enhances its mechanical properties such as bending and shear resistance, forming a more robust structure. The load-bearing rod 2221 provides an additional force transmission path, allowing the force of water waves to be transferred from the outer baffle 221 to the vegetation board 211, thus improving the protective effect.

[0035] Furthermore, a rope hole 2211 is provided through the baffle 221 for threading ropes. The rope is generally a steel strand, which provides an additional connection function for splicing multiple ecological slope protection support structures. This facilitates the use of steel strands for binding or reinforcement during construction or maintenance, improves overall stability, and makes the construction process more convenient and safer.

[0036] Furthermore, a porous reinforcing strip 14 connects the vegetation board 211 and the dam body 1, and the precast block 12 is provided with multiple return holes 121 that cooperate with the porous reinforcing strip 14. The porous reinforcing strip 14 helps to transfer the load on the vegetation board 211, reduces local stress concentration, and improves the stability of the structure. At the same time, when the root system in the vegetation bag 3 develops and reduces the water permeability of the fine pores 13 of the dam body 1, water can flow down through the upper surface of the dam body 1 under the action of gravity along the multiple small holes of the porous reinforcing strip 14. The return holes 121 connect the outside world with the space between the vegetation board 211 and the dam body 1, allowing the water flowing through the multiple small holes of the porous reinforcing strip 14 to flow out to the outside world and return to the river channel. The return holes 121, in conjunction with the porous reinforcing strip 14, can promote water discharge, reduce water erosion of the dam body 1, and enhance the dam body 1's resistance to water impact.

[0037] Furthermore, the counterweight 11 has a connecting block 111 at one end and a corresponding connecting groove 112 at the other end; a second truss 113 is provided on the connecting block 111, and a pouring hole 114 is opened in the counterweight 11 to pass through the connecting groove 112. The connecting block 111 and the connecting groove 112 are designed to be used for splicing multiple ecological slope protection support structures. After the splicing is completed, a strip template is added behind the counterweight 11, and concrete is poured through the pouring hole 114 to improve the connection strength between multiple ecological slope protection support structures. The second truss 113 is used to improve the bonding strength and mechanical properties of the cast-in-place concrete.

[0038] Furthermore, the precast block 12 has a square groove 122, and a third truss 123 is provided on the bottom surface of the square groove 122. The two ends of the third truss 123 are respectively provided with inserts 1231 and slots 1232, and each insert 1231 and slot 1232 has two corresponding pin holes. The inserts 1231 and slots 1232 on the third truss 123 are used for splicing multiple ecological slope protection support structures. After the insert 1231 is inserted into the slot 1232, a pin is driven into the pin hole; then concrete is poured into the square groove 122, and the insert 1231, slot 1232 and pin are all submerged in the cast-in-place concrete.

[0039] Specific application examples

[0040] Ecological slope protection technology, as an effective means of soil stabilization and protection, is applied in the fields of soil and water conservation and slope reinforcement. With increasing emphasis on environmental protection and sustainable development, traditional hard slope protection is gradually transforming into ecological slope protection to achieve the restoration and protection of ecosystems. By utilizing the natural forces of plant roots and ecological structures, not only can slope stability be improved, but also soil erosion can be effectively resisted, the risk of scouring and erosion reduced, and the durability and environmental friendliness of the project enhanced. This utility model provides an ecological slope protection support structure for water conservancy and hydropower projects, the main body of which is a semi-assembled precast concrete component. The usage method is briefly described below:

[0041] 1. Foundation construction stage

[0042] The slope surface is modified, and the ecological slope protection support structure of this utility model for water conservancy and hydropower projects is placed at the corresponding position on the slope surface. The piles are driven into the soil using the precast pile construction method so that the ecological slope protection support structure fits the slope surface.

[0043] 2. Assembly stage

[0044] Multiple ecological slope protection support structures are spliced ​​along the slope surface; during splicing, the connecting block 111 and the connecting groove 112 should correspond, the insert 1231 of the third truss 123 should correspond to the slot 1232 and the pin should be driven out, and the steel stranded rope passes through the rope hole 2211 on the baffle 221 of the multiple ecological slope protection support structures and is tightened and the outer end is anchored.

[0045] 3. Concrete pouring stage

[0046] A template is installed on the rear side of the counterweight block 11, and templates are pressed on the sides of multiple ecological slope protection support structures. The gaps between multiple ecological slope protection support structures are filled with sealant.

[0047] After the formwork is installed, concrete is poured. This includes pouring into the pouring hole 114, pouring into the square groove 122, and pouring into the truss reinforcement component 22. After pouring, it can be vibrated or hammered with a rubber mallet.

[0048] 4. Installation and maintenance of planting bags

[0049] After the concrete has been poured and hydrated for 3 days (or other), place planting bags 3 into the planting holes 2121 of the vegetation protection dam component 21. Then, regularly water the plants in the planting bags 3 to ensure healthy root growth, allowing them to gradually penetrate and wrap around the fine channels 13 of the dam body 1, extending their roots into the soil between the dam body 1 and the slope. During this process, moisture will seep into the cast-in-place concrete portion of the truss reinforcement component 22, providing a curing effect.
