Description

Technical Field

[0001] This utility model relates to the field of water conservancy slope protection technology, and specifically discloses an eco-friendly water conservancy slope protection method. Background Technology

[0002] Slope protection refers to all paving and planting work done on slope surfaces to prevent erosion. In the river section where the bridge is located, the concave bank is subject to erosion by the water flow year after year, causing it to continuously collapse. To protect the safety of bridges and embankments, protective structures must be built on the concave bank. In addition, when the construction of a bridge causes changes in the river's flow direction, eroding the riverbank and endangering farmland and villages, protective structures must also be built on the riverbank.

[0003] For example, patent CN208995983U discloses a green and environmentally friendly ecological slope protection for water conservancy projects, including a wall. A vertical fixing base is provided on one side of the wall. A thickened concrete layer is provided at the upper end of the wall and the vertical fixing base. A horizontal fixing base is provided on one side of the lower end of the vertical fixing base. A triangular soil base is provided at the upper end of the horizontal fixing base. A sand cushion layer is provided at the upper end of the triangular soil base. A wire mesh parallel to the sand cushion layer is provided in the sand cushion layer. Several wire mesh holes are evenly provided on the wire mesh. By providing water passage holes in the slope protection bricks, not only can the soil's resistance to water erosion be effectively improved, but also rainwater accumulated in the hollow grooves of the slope protection bricks can be drained during rainy days, preventing the roots of the green plants at the bottom of the slope protection bricks from rotting. By providing fixing nails, with one end of the fixing nails passing through the green planting layer, the gravel and sand layer, the sand cushion layer, and the wire mesh and extending into the triangular soil base layer, the slope protection can be well fixed, strengthening the stability of the slope protection and increasing its service life.

[0004] Limitations of existing technology:

[0005] Without buffer structures (such as wave walls or riprap foundations) designed for waves or rapid currents, they are easily damaged at high water levels; lacking internal reinforcement layers (such as steel mesh or cement-stabilized base), they may crack after long-term use; relying on surface vegetation without systematically combining permeable materials and layered protection limits ecological benefits, and being frequently eroded by rainwater can easily form gullies that need to be filled regularly.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-5 An eco-friendly water conservancy slope protection method includes a slope protection body 1, which comprises a reinforced slope 2 with one side vertical and the other inclined, and an inclined retaining wall revetment 3 located on the inclined side of the reinforced slope 2. The bottom of the inclined retaining wall revetment 3 is provided with a plain concrete cushion layer 4, which is buried below the ground surface. The bottom area of ​​the inclined retaining wall revetment 3 is larger than its top area. A cement-stabilized crushed stone base layer 5, located within the reinforced slope 2, is inclined downwards in the middle of one side of the inclined retaining wall revetment 3. A flow-blocking dam 6 in the shape of an isosceles trapezoid is located on top of the cement-stabilized crushed stone base layer 5. The upper end of the flow-blocking dam 6 extends above the reinforced slope 2. A wave-breaking wall 7 is vertically installed above the side of the inclined retaining wall revetment 3 away from the reinforced slope 2. A flow-guiding channel 8 is opened on the top of the wave-guiding wall 7. Water-retaining walls 9 are fixedly connected to the inclined retaining wall revetment 3 on both sides of the flow-guiding channel 8. A flow-guiding step 10 is provided between the two water-retaining walls 9. A riprap footing 11 is provided below the side of the inclined retaining wall revetment 3 away from the cement-stabilized crushed stone base 5. The end of the riprap footing 11 away from the inclined retaining wall revetment 3 is higher than the other end, and the top of the riprap footing 11 is curved.

[0027] In this embodiment: the slope protection body 1 adopts a combined structure of reinforced slope body 2 and inclined retaining wall revetment body 3. The retaining wall design with a bottom area larger than the top enhances the overturning resistance. Combined with plain concrete cushion layer 4 and riprap foundation 11, it disperses the impact force of water flow and prevents slope collapse, forming a gravity structure that improves the overturning safety factor. The buried depth of plain concrete cushion layer 4 effectively improves the foundation bearing capacity. The cement-stabilized crushed stone base layer 5 extends into the interior of reinforced slope body 2, forming a composite force transmission system to achieve primary energy dissipation. The guide channel 8 at the top of the wave wall 7 and the water retaining walls 9 on both sides... The water flow is guided to be discharged in an orderly manner along the guide steps 10, avoiding concentrated scouring and mitigating the impact of the water flow in layers. This reduces the water flow velocity and the impact on the inclined retaining wall revetment 3, thus providing protection. The riprap foundation 11 forms a self-compacting structure, improving the resistance to water scouring. At the same time, the cement-stabilized crushed stone base 5 and the flow barrier 6 form an internal drainage channel, reducing the erosion of the slope by rainwater infiltration. Furthermore, the curved design of the riprap foundation 11 and the diversion pipe 23 further disperse the water flow, reducing the risk of bottom scouring, making it less likely to damage the revetment, and eliminating the need for regular filling.

[0028] As a technical optimization of this utility model, the retaining wall revetment 3 on the side facing away from the reinforced slope 2 is composed of a concrete layer 12, a protective cushion layer 13, a transition layer 14, and a main rockfill layer 15 in sequence.

[0029] In this embodiment: The concrete layer 12 functions as an anti-seepage layer. The protective cushion layer 13 provides a flat and dense foundation for the concrete layer 12 and transmits the water pressure, playing an auxiliary seepage role. The transition layer 14 is used to protect the protective cushion layer 13 from being damaged; the main rockfill layer 15 plays a supporting role, strengthening the stability of the slope protection body 1 and enhancing the protection strength of the slope protection body 1 for the soil slope.

[0030] As a preferred ecological and environment-friendly water conservancy slope protection of the present utility model, a number of longitudinally parallel joint mortar strips 16 are provided in the concrete layer 12, and a steel mesh 17 is provided between two adjacent joint mortar strips 16. Anchor bars 18 inserted into the protective cushion layer 13 are provided in the steel mesh 17.

[0031] In this embodiment: By arranging the parallel joint mortar strips 16, the large-area concrete layer 12 is divided into several strip-shaped units, effectively reducing the crack expansion caused by temperature change or shrinkage and preventing the generation of penetrating cracks; the steel mesh 17 enhances the structural toughness. The steel mesh 17 is arranged between two adjacent joint mortar strips 16 to form a grid-shaped strengthening system, significantly enhancing the tensile strength and bending resistance of the concrete layer 12 and avoiding fractures caused by local stress concentration; the anchor bars 18 in the steel mesh 17 are inserted downward into the protective cushion layer 13 to form rigid anchoring points, tightly connecting the concrete layer 12 with the lower protective cushion layer 13, preventing the slope protection from delaminating and peeling due to water flow scouring or soil body sliding; enabling the concrete layer 12 to be stressed jointly by the joint mortar strips 16, the steel mesh 17 and the steel bars, with the joint mortar strips 16 restricting the shrinkage deformation of the concrete, the steel mesh 17 evenly distributing the load, and the anchor bars 18 providing the vertical anchoring force. The three work together to significantly enhance the overall stability of the slope protection;

[0032] The joint mortar strips 16 are in a "丄" shape, and the two sides of the joint mortar strips 16 are fixed using the anchor bars 18.

[0033] As a preferred ecological and environment-friendly water conservancy slope protection of the present utility model, a reinforcement base 19 is provided at the bottom of the reinforced slope body 2 and the plain concrete cushion layer 4, and the bottom of the reinforcement base 19 is in a curved surface shape; foundation piles 20 are vertically provided at the bottom of the reinforced slope body 2 and the plain concrete cushion layer 4.

[0034] In this embodiment: The reinforcement base 19 and the foundation piles 20 can more evenly disperse the load of the slope protection structure, reduce the stress concentration of the foundation, and prevent local settlement or collapse; the vertically arranged foundation piles 20 penetrate into the stable formation and are rigidly connected to the reinforced slope body 2 and the plain concrete cushion layer 4, significantly improving the anti-overturning and anti-sliding capabilities, especially suitable for soft soil foundations or high water level working conditions.

[0035] As a preferred ecological and environment-friendly water conservancy slope protection of the present utility model, an impact wall 21 fixedly connected to the top of the slope protection body 1 is inclined on the wave wall 7, and a number of through holes 22 are opened at the top of the impact wall 21.

[0036] In this embodiment: the through hole 22 at the top of the impact wall 21 effectively mitigates the impact of water on the retaining wall 9, weakens the wave impact force, strengthens the base 19 and the foundation pile 20 to improve the bearing capacity of the foundation and prevent settlement.

[0037] As a preferred ecological and environmentally friendly water conservancy slope protection method of this utility model, the side of the riprap foundation 11 away from the inclined retaining wall bank body 3 is provided with a drainage pipe 23 connected to the top.

[0038] In this embodiment, the drainage pipe 23 can transport water to a designated area for use, such as irrigation.

[0039] Working principle and usage process of this utility model:

[0040] The inclined retaining wall revetment 3 adopts a variable cross-section design with a bottom area larger than the top area, forming a gravity structure. By increasing the bottom contact area, the overturning safety factor is improved. The plain concrete cushion layer 4 effectively improves the foundation bearing capacity by increasing the embedment depth. The cement-stabilized crushed stone base layer 5 extends into the interior of the slope, forming a composite force transmission system to achieve primary energy dissipation. The riprap footing 11 forms a self-compacting structure, improving the resistance to water erosion. The retaining wall 9 and the guide steps 10 form a stepped guide channel. Together with the guide channel 8 at the top of the wave wall 7, the water flow impact force can be reduced in layers, the water flow velocity can be reduced, and the water flow can be concentrated to reduce the impact on the inclined retaining wall revetment 3, thus playing a protective role. At the same time, the directional diversion of the guide channel 8 avoids local erosion of the slope toe. The through hole 22 at the top of the impact wall 21 effectively alleviates the impact of water on the retaining wall 9, saturates the retaining wall 9, and is not easy to damage the slope protection, so it does not need to be filled regularly. The slope protection stress can be dispersed by strengthening the base 19 and the foundation piles 20.
