Vegetation protection slope water and soil conservation structure

Abstract

This application relates to the field of slope protection and soil and water conservation construction technology, specifically to a vegetation-supported slope protection and soil and water conservation structure. The structure comprises multiple concrete frames, each a quadrilateral frame; two adjacent concrete frames are joined together laterally via a first connector; two adjacent concrete frames are joined together longitudinally via a second connector; the thickness of the side components on both sides of each concrete frame gradually increases from its top to its bottom. The proposed solution uses connectors to link adjacent concrete frames laterally and longitudinally, resulting in a more stable connection. By designing the side components on both sides of the concrete frame to gradually increase in thickness from their top to their bottom, the top of the side components is embedded in the soil at a shallow depth when the concrete frame is laid on the slope. This allows the vegetation roots within adjacent concrete frames to intertwine and entwine, further enhancing the stability of the connection between the structure and the slope.

Description

Technical Field

[0001] This application relates to the field of slope protection and soil and water conservation repair technology, specifically to a vegetation slope protection and soil and water conservation structure. Background Technology

[0002] With the deepening of ecological civilization construction, slope protection engineering has shifted from a single structural safety objective to a comprehensive objective that also considers ecological restoration and landscape functions. Traditional engineering slope protection techniques (such as retaining walls, anchor-sprayed supports, and grouted rubble masonry) offer good erosion resistance, but their ecological and landscape effects are relatively poor. In contrast, vegetation-based slope protection combines both protective and environmental benefits; it is not only inexpensive and beautifies the environment, but also reduces soil erosion on slopes and provides long-lasting slope protection.

[0003] Ecological slope protection technology has emerged and become an important part of slope protection engineering. However, relying solely on vegetation for slope protection has natural limitations in terms of structural stability, especially in areas with steep slopes, heavy rainfall erosion, or complex geological conditions. The soil-fixing capacity of vegetation roots is insufficient to meet the safety requirements of the project. Ecological composite slope protection technology, which combines the structural advantages of engineering slope protection with the ecological advantages of plant slope protection, has become the mainstream application direction.

[0004] In engineering practice, precast concrete grid slope protection is widely used due to its convenient construction and reliable structure. However, existing ecological slope protection methods have the following main shortcomings: First, insufficient structural stability. Conventional precast concrete slope protection structures (such as rectangular lattice beams and rectangular frame slope protection) typically have rectangular or trapezoidal cross-sections, resulting in a small contact area with the slope soil. They primarily rely on bottom surface friction to provide anti-sliding force. During long-term service, they are susceptible to uneven settlement, sliding, or overturning due to factors such as rainwater infiltration, freeze-thaw cycles, and soil creep, affecting the long-term safety of the slope protection.

[0005] Second, poor connection reliability The connection between adjacent components is a critical weak point in prefabricated slope protection structures. In existing technologies, the main methods of lateral connection include the following: (1) Rebar connection: Rebars or bolts are inserted into the reserved holes. High construction accuracy is required and the amount of on-site work is large. (2) Reserved through-hole steel bar + cast-in-place sealing anchor: requires on-site formwork or secondary pouring, the process is complicated, and the shear and pull-out resistance of the connection node is limited, and it is easy to loosen after long-term use.

[0006] Third, poor ecological compatibility. Traditional slope protection components are mostly solid concrete structures or frames with small meshes, making it difficult for plant roots to penetrate the concrete layer and extend to the slope soil, thus hindering the horizontal and vertical exchange of soil moisture and nutrients.

[0007] Fourth, in recent years, a technical solution has emerged that involves reserving planting holes in concrete frames. However, the number of reserved holes is limited and their distribution is uneven, making it difficult to form a continuous root channel and water-soil exchange network. As a result, the vegetation coverage and plant survival rate are still not ideal. Summary of the Invention

[0008] The purpose of this application is to design a vegetation-supported slope protection and soil and water conservation structure, aiming to solve the problems of insufficient stability and poor reliability of existing ecological slope protection structures.

[0009] This application relates to a vegetation slope protection and soil and water conservation structure, the conservation structure comprising multiple concrete frames, the concrete frames being quadrilateral frame structures; two adjacent concrete frames along the transverse direction are joined together by a first connector; two adjacent concrete frames along the longitudinal direction are joined together by a second connector; the thickness of the side components on both sides of each concrete frame gradually increases from its top to its bottom.

[0010] In some implementations, the concrete frame is a monolithic reinforced concrete structure; the side members are projected in a triangular shape along the lateral direction.

[0011] In some embodiments, the first connector is a transverse connector; the side component is provided with a connecting groove; the transverse connector is respectively engaged with the connecting groove of the side component of two adjacent concrete frames.

[0012] In some embodiments, the width of the connecting groove gradually increases from its top to its bottom; one end of the transverse connector abuts against one side of the top of the connecting groove, and the other end of the transverse connector abuts against the inner wall of the bottom of the connecting groove.

[0013] In some embodiments, the transverse connector includes a perforated component and a support component; the perforated component has side ears on both sides of its top end, and a pull member is provided between the side ears on both sides; the perforated component has a positioning groove at its bottom end; the support component has a back plate at its bottom end; one end of the support component can be engaged in the positioning groove laterally, and the other end of the support component abuts against the inner wall of the bottom end of the connecting groove through the back plate; the perforated component abuts against one side of the top end of the connecting groove through the pull member.

[0014] In some embodiments, a shallow component is provided on one side of the top of each concrete frame, and a deep component is provided on one side of the bottom of each concrete frame; the thickness of the deep component is greater than the thickness of the shallow component; the shallow component is embedded in the soil layer on the top side of the slope, and the deep component is embedded in the soil layer on the bottom side of the slope, so that the surface of the concrete frame is parallel to the slope; the depth to which the deep component is embedded in the soil layer is greater than the depth to which the shallow component is embedded in the soil layer.

[0015] In some embodiments, the deep component has a connection port; the second connector is a longitudinal connector; the shallow component of the concrete frame can overlap the deep component of the adjacent concrete frame; the longitudinal connector is provided on the deep component and engages with the shallow component overlapping the deep component through the connection port.

[0016] In some embodiments, the upper surface of the deep component is provided with a step; the shallow component of the concrete frame can overlap the step of the deep component of the adjacent concrete frame so that the surfaces of the two adjacent concrete frames are flush with each other.

[0017] In some embodiments, the longitudinal connector includes a lower hook and an upper hook; the lower hook and the upper hook are respectively disposed on both sides of the deep component; one end of the lower hook is provided with a snap-fit ​​portion, and the other end of the lower hook is provided with an abutment portion; the lower hook engages with the bottom of the deep component through the snap-fit ​​portion, and the abutment portion abuts against the shallow component overlapping the deep component; one end of the upper hook is provided with a hook portion; the upper hook engages with the shallow component overlapping the deep component through the hook portion; the lower hook and the upper hook are connected by a butt joint.

[0019] The vegetation slope protection and soil and water conservation structure proposed in this application has the following technical advantages: (1) The vegetation slope protection and soil and water conservation structure proposed in this application is connected in the transverse and longitudinal directions of adjacent concrete frames through connectors. In this way, the concrete frame connection of the entire protection structure is more stable and not easy to detach or loosen. When the overall structure is under stress, the load can be transferred and distributed between adjacent concrete frames, avoiding chain failure caused by single-point failure. (2) The vegetation slope protection and soil and water conservation structure proposed in this application is designed so that the thickness of the side components on both sides of the concrete frame gradually increases from the top to the bottom. This makes the soil layer embedded at the top of the side components shallower when the concrete frame is laid on the slope. The vegetation roots in the two adjacent concrete frames can intertwine and entwine with each other, eventually forming an integrated vegetation network on the slope and connecting more stably with the slope. (3) The vegetation slope protection and soil and water conservation structure proposed in this application forms a drop between the top and bottom of the concrete frame. The top is embedded in the top soil layer at a shallow depth, while the bottom is embedded in the bottom soil layer at a deeper depth. This enables lateral water and soil flow and facilitates vegetation growth. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0031] like Figure 1As shown, this application proposes a vegetation-based slope protection and soil and water conservation structure, specifically relating to a vegetation-based slope protection and soil and water conservation structure for use in water conservancy projects, highway slopes, municipal greening, and other fields. Specifically, the protection structure of this application includes multiple concrete frames 1, which are connected to form the protection structure. Each concrete frame 1 has the same structure and is arranged in a grid pattern on the slope surface. The concrete frames 1 are precast concrete frames, which facilitates uniform processing and molding, ensures the accuracy of frame dimensions and concrete quality, and avoids quality fluctuations caused by weather, personnel operations, and other factors during on-site pouring. The concrete frame 1 is a quadrilateral frame structure, which facilitates the connection between adjacent concrete frames 1. The connection structure is relatively flat, allowing the formation of regular transverse cells on the slope. When rainfall or surface runoff flows down the slope, the transverse borders of the quadrilateral frame structure divert and guide the water flow, directing the slope runoff into the frame interior and preventing concentrated erosion of the slope soil. Simultaneously, the transverse cells act as a confinement for the filling soil, preventing the loss of planting soil under rainfall erosion conditions, achieving a soil and water conservation effect of "protecting the soil with the structure." More specifically, in the retaining structure, two adjacent concrete frames 1 are joined together laterally via a first connector, and two adjacent concrete frames 1 are joined together longitudinally via a second connector. This makes the concrete frame connections of the entire retaining structure more stable, less prone to detachment and loosening. When the overall structure is under stress, the load can be transferred and distributed between adjacent concrete frames, avoiding cascading failures caused by single-point failure. Further, refer to... Figure 2 and Figure 8 As shown, the side components 101 on both sides of each concrete frame 1 in this application have the same structure. The thickness h of the side component 101 gradually increases from its top to its bottom. Therefore, the top of the side component 101 is embedded in the soil layer relatively shallowly, allowing the root systems of vegetation in adjacent concrete frames 1 to intertwine and entwine with each other, ultimately forming an integrated vegetation network on the slope, thus maintaining a more stable connection between the structure and the slope. The thickness of the shallow component 103 at the top of each concrete frame 1 is the same as the thickness of the top of its side component 101, and the thickness of the deep component 104 at the top of each concrete frame 1 is the same as the thickness of the bottom of its side component 101. This design allows the shallow component 103 to be embedded in the soil layer at a shallow depth when the concrete frame 1 is laid on the slope, thus allowing water and soil flow below it; while the deep component 104 is embedded in the soil layer at a deeper depth, which can form a limiting and fixing effect in the lateral direction, improving stability.

[0032] like Figure 2 and Figure 8As shown, in some embodiments, the concrete frame 1 is a one-piece reinforced concrete structure. The concrete frame 1, the first connector, and the second connector in this application are all made of high-strength concrete, resulting in good structural durability, low maintenance requirements, reliable connections, and resistance to loosening, thus reducing maintenance costs during operation. More importantly, the vegetation slope protection and soil and water conservation structure proposed in this application promotes the intertwined growth of vegetation roots to form an integrated vegetation network, resulting in rapid vegetation recovery and high coverage, reducing the cost of replanting and repairing the slope later. By combining the structure's long lifespan with the ecosystem's rapid self-repair capability, the overall life-cycle cost is significantly lower than existing solutions. Specifically, the side component 101 is a triangular structure, meaning its transverse projection is triangular. The apex of this triangular structure can embed into the slope soil, changing the traditional rectangular cross-section lattice beam's reliance solely on bottom friction to resist sliding forces, thereby improving the stability of the concrete frame 1. The triangular structure design embeds the concrete frame into the soil, increasing the anti-sliding component embedded in the soil and forming an integrated "anchoring-support" anti-sliding system. Even if the soil moisture content on the slope increases and the friction coefficient decreases, the embedding effect of the triangular structure tip can still provide continuous anti-sliding force, and the anti-sliding capacity can be improved by more than 30%.

[0033] like Figure 1-2 , Figure 6-7 As shown, in some embodiments, the first connector is a transverse connector 2. Each side component 101 of the concrete frame 1 is provided with a connecting groove 102. The side components 101 and their connecting grooves 102 of two transversely adjacent concrete frames 1 are aligned with each other. Specifically, the transverse connector 2 is respectively engaged with the connecting grooves 102 of the side components 101 of two adjacent concrete frames 1 to join the two transversely adjacent concrete frames 1 together, preventing them from separating and forming a stable joint structure.

[0034] like Figure 6-8 As shown, in some embodiments, the width of the connecting groove 102 gradually increases from its top to its bottom to accommodate the engagement of the transverse connector 2. During installation, the transverse connector 2 is inserted transversely into the connecting groove 102 to form an abutment structure. Specifically, one end of the transverse connector 2 abuts against one side of the top of the connecting groove 102, and the other end of the transverse connector 2 abuts against the inner wall of the bottom of the connecting groove 102.

[0035] like Figure 5-7As shown, in some embodiments, the transverse connector 2 includes a perforated component 201 and a support component 205. The perforated component 201 has side ears 202 on both sides of its top end, and a tie member 203 is provided between the side ears 202. The transverse cross-section of the perforated component 201 is trapezoidal, and the bottom end of the perforated component 201 has a positioning groove 204. The bottom end of the support component 205 has a back plate 206, and the back plate 206 and the support component 205 are an integral structure. Specifically, one end of the support component 205 can be transversely engaged in the positioning groove 204, and the other end of the support component 205 abuts against the inner wall of the bottom end of the connecting groove 102 through the back plate 206, forming an assembly structure. Further, the perforated component 201 abuts against one side of the top end of the connecting groove 102 through the tie member 203, and the two side ears 202 are engaged on the outside of the side component 101, realizing that the transverse connector 2 clamps and fixes the side components 101 of the two concrete frames 1.

[0036] like Figure 1-2 As shown, in some embodiments, a shallow component 103 is provided on one side of the top of each concrete frame 1, and a deep component 104 is provided on one side of the bottom of each concrete frame 1. The second connector is a longitudinal connector 3, which connects the deep component 104 and the shallow component 103 of two adjacent concrete frames 1 in the longitudinal direction to form an overlap for force transmission. This allows the downward force of the upper frame to be transmitted to the lower frame through the longitudinal connector 3, forming a force chain of layered unloading, effectively resisting the overall slope slippage trend. The shallow component 103 is located at a lower position above the slope (near the top of the slope), while the deep component 104 is located at a higher position below the slope (near the bottom of the slope), creating a height difference in the longitudinal direction of the slope. When the transverse water flow encounters the inclined side of the triangular cross-section along the horizontal direction of the slope, the water flow is guided to infiltrate into the slope soil, transforming "surface runoff" into "soil infiltration flow," reducing surface runoff, reducing erosion of the slope soil, and realizing the water and soil conservation function of "guiding flow by shape and retaining water by infiltration". The thickness of the deep component 104 is greater than that of the shallow component 103, allowing the deep component 104 to be embedded deeper into the soil than the shallow component 103. Specifically, the shallow component 103 is embedded in the soil layer on the top side of the slope, while the deep component 104 is embedded in the soil layer on the bottom side of the slope, ensuring that the surface of the concrete frame 1 is parallel to the slope and maintaining the overall flatness of the slope. The deep component 104 of each concrete frame 1 extends outward by a certain width, forming a large surface area in contact with the slope soil, thus improving anti-sliding capacity. The large surface area contact of the deep component 104 effectively reduces the concentration of compressive stress on the slope surface from the concrete frame, preventing localized settlement, while simultaneously increasing the friction between the bottom of the concrete frame and the slope surface, further enhancing anti-sliding stability.

[0037] like Figure 1-4As shown, in some embodiments, the deep component 104 is provided with at least one connection port 106; the connection port 106 is preferably a U-shaped interface, which facilitates processing and forming. The second connector is a longitudinal connector 3. The shallow component 103 of the concrete frame 1 can be flush-attached to the deep component 104 of the adjacent concrete frame 1; the longitudinal connector 3 is provided on the deep component 104 and engages with the shallow component 103 overlapping the deep component 104 through the connection port 106, thereby joining the two adjacent concrete frames 1 together.

[0038] like Figure 1-3 As shown, in some embodiments, the upper end face of the deep component 104 is provided with a step 107. The shallow component 103 of the concrete frame 1 can overlap the step 107 of the deep component 104 of the adjacent concrete frame 1 so that the surfaces of the two adjacent concrete frames 1 are flush with each other. At the same time, the step 107 can play a limiting role to prevent the two adjacent concrete frames 1 from loosening in the longitudinal direction.

[0039] like Figure 1-4 As shown, in some embodiments, the longitudinal connector 3 includes a lower hook 301 and an upper hook 305. The lower hook 301 and the upper hook 305 are respectively disposed on both sides of the deep component 104, that is, the deep component 104 is clamped between the lower hook 301 and the upper hook 305. One end of the lower hook 301 is provided with a snap-fit ​​portion, and the other end of the lower hook 301 is provided with an abutment portion; specifically, the lower hook 301 engages with the bottom of the deep component 104 through the snap-fit ​​portion, and the lower hook 301 abuts against the shallow component 103 overlapping the deep component 104 through the abutment portion. Furthermore, one end of the upper hook 305 is provided with a hook portion; specifically, the upper hook 305 engages with the shallow part 103 overlapping the deep part 104 through the hook portion; the lower hook 301 and the upper hook 305 are connected by a mating part so that they can engage with each other to clamp the deep part 104 and the shallow part 103 overlapping the deep part 104. Specifically, the snap-fit ​​part includes a side plate 3011, a bottom plate 3012, and a hook plate 3013, which are integral structures. The bottom plate 3012 is connected between the side plate 3011 and the hook plate 3013 and corresponds to the bottom of the deep component 104. The hook plate 3013 is connected to one side of the bottom plate 3012 and forms a preset angle with the vertical surface of the deep component 104. The hook plate 3013 is snap-fitted onto the side of the deep component 104 away from the side plate 3011.

[0040] like Figure 1-4As shown, in some embodiments, the lower hook 301 has a through hole. The upper hook 305 includes a main body 3051, on which a fitting 304 is provided, and the fitting 304 has a threaded hole 3052. The mating member can be a screw 302. The main body 3051 is disposed in the connection port 106; the screw 302 passes through the through hole and connects with the threaded hole 3052, thereby engaging the lower hook 301 and the upper hook 305 together.

[0041] The vegetation slope protection and soil and water conservation structure proposed in this application has the following technical advantages: (1) The vegetation slope protection and soil and water conservation structure proposed in this application is connected in the transverse and longitudinal directions of adjacent concrete frames through connectors. In this way, the concrete frame connection of the entire protection structure is more stable and not easy to detach or loosen. When the overall structure is under stress, the load can be transferred and distributed between adjacent concrete frames, avoiding chain failure caused by single-point failure. (2) The vegetation slope protection and soil and water conservation structure proposed in this application is designed so that the thickness of the side components on both sides of the concrete frame gradually increases from the top to the bottom. This makes the soil layer embedded at the top of the side components shallower when the concrete frame is laid on the slope. The vegetation roots in the two adjacent concrete frames can intertwine and entwine with each other, eventually forming an integrated vegetation network on the slope and connecting more stably with the slope. (3) The vegetation slope protection and soil and water conservation structure proposed in this application forms a drop between the top and bottom of the concrete frame. The top is embedded in the top soil layer at a shallow depth, while the bottom is embedded in the bottom soil layer at a deeper depth. This enables lateral water and soil flow and facilitates vegetation growth.
