Description

Technical Field

[0001] This application relates to the field of revetment pile technology, and in particular to a concrete ecological revetment pile. Background Technology

[0002] Traditional bank protection projects often employ reinforced concrete piles, masonry revetments, or precast concrete blocks, technologies that have played a vital role in soil and water conservation and flood control.

[0003] However, with increasing demands for ecological and environmental protection, traditional bank protection technologies have gradually revealed their insufficient ecological functions. In recent years, ecological bank protection technology has become a research hotspot, mainly improving the ecological benefits of bank protection through methods such as vegetation restoration and porous structure design. However, existing ecological bank protection technologies still have certain limitations in terms of structural strength and durability. To address these issues, a concrete ecological bank protection pile has been proposed. Utility Model Content

[0004] The purpose of this application is to provide a concrete ecological revetment pile, in which the composite revetment pile body and the ecological guidance component work together to improve the survival rate of vegetation and effectively enhance the overall erosion resistance of the revetment, thus solving the problems mentioned in the background art.

[0005] The present application provides a concrete ecological revetment pile with the following technical solution: a concrete ecological revetment pile includes a composite revetment pile body, the composite revetment pile body is a three-layer composite structure, from the inside to the outside are a high-strength concrete core layer, a self-healing concrete layer and a porous recycled concrete layer, the high-strength concrete core layer is pre-embedded with a steel reinforcement skeleton, the self-healing concrete layer is filled with a first filler, and the porous recycled concrete layer is filled with a second filler.

[0006] The composite revetment pile body is equipped with an ecological guidance component inside. The ecological guidance component includes a reserved cavity at the top of the composite revetment pile body. A polymer fiber mesh is fixedly connected to the inner wall of the reserved cavity. Ecological boards are embedded on both sides of the composite revetment pile body. Each ecological board has multiple ecological holes on its inner wall. The multiple ecological holes are arranged in a honeycomb pattern inside the ecological board. The inner wall of each ecological hole is coated with a biocompatible coating. The multiple ecological holes are connected to the reserved cavity. A connecting component is provided on the outside of the composite revetment pile body.

[0007] By adopting the above technical solution, the three-layer composite structure of the composite revetment pile and the ecological guidance components work synergistically. The high-strength concrete core layer provides the strength of the basic structure, the self-healing concrete layer enables the self-repair of cracks, the porous recycled concrete layer creates a plant growth environment, and the steel skeleton enhances the overall bending resistance. This allows the revetment pile to have both structural stability and ecological functionality, effectively solving the problem of balancing strength and ecology in traditional revetment technology. Furthermore, the plant roots can grow laterally through the ecological holes, intertwining with the plant roots inside the adjacent composite revetment pile to form a network structure, enhancing the overall stability.

[0008] Preferably, the reinforcing steel skeleton is made of HRB400 grade threaded steel, the first filler is a mixture of Bacillus pasteurellii and calcium carbonate precursor, and the second filler is a mixture of waste ceramic particles and superabsorbent resin.

[0009] By adopting the above technical solutions, the steel reinforcement cage is made of HRB400 grade threaded steel, which improves the tensile and compressive strength of the composite revetment pile body and works in conjunction with the high-strength concrete core layer to resist the impact of water flow. The mixture of Pasteurella multocida and calcium carbonate precursor in the self-healing concrete layer activates the mineralization reaction when microcracks appear in the composite revetment pile body, generating calcium carbonate crystals to fill the cracks, realizing the self-healing function and extending the service life of the composite revetment pile body. The mixture of waste ceramic particles and superabsorbent resin in the porous recycled concrete layer increases the porosity and maintains soil moisture, providing a good foundation for vegetation growth.

[0010] Preferably, the top of the reserved cavity is filled with a top nutrient soil layer, and the bottom of the reserved cavity is filled with a bottom nutrient soil layer.

[0011] By adopting the above technical solution, the cavity is filled with a top nutrient soil layer and a bottom nutrient soil layer, which provides long-term nutrient supply for surface plants. The top nutrient soil layer collects rainwater or surface water, and the bottom nutrient soil layer is connected to the ecological hole, forming a vertical water and nutrient transport channel, which improves the survival rate of vegetation and is especially suitable for the plant growth needs in areas with fluctuating water levels.

[0012] Preferably, the polymer fiber mesh is located between the top nutrient soil layer and the bottom nutrient soil layer, and the polymer fiber mesh is located above the ecological board.

[0013] By adopting the above technical solution, the polymer fiber net is located between the top and bottom nutrient soil layers and is set above the ecological board. It can effectively block fallen leaves, mud and other debris from entering the ecological holes, avoid clogging of the holes, and at the same time allow water and nutrients to penetrate. While ensuring the unobstructed flow of the ecological holes, it maintains the stability of the plant root growth environment.

[0014] Preferably, the connecting assembly includes two T-shaped connecting blocks fixedly connected to one side of the composite revetment pile body, and two T-shaped connecting grooves are opened on the other side of the composite revetment pile body, with the dimensions of the T-shaped connecting blocks and the T-shaped connecting grooves being compatible.

[0015] By adopting the above technical solution, the T-shaped connecting block and T-shaped connecting groove of the connecting component are matched in size, so that the adjacent composite revetment piles form a mechanical interlocking structure, which enhances the overall rigidity of the revetment. Together with the steel reinforcement skeleton inside the composite revetment pile and the external barbed protrusion, a three-dimensional anchoring system is formed, which effectively resists the scouring force of water flow and improves the overall stability of the revetment project.

[0016] Preferably, the outer surface of the composite revetment pile body is fixedly connected with uniformly distributed barbed protrusions.

[0017] By adopting the above technical solution, the barbed protrusions are evenly distributed on the surface of the composite revetment pile body, increasing the frictional resistance between the composite revetment pile body and the surrounding soil and water flow. When the water flows through, a turbulent zone is formed behind the protrusions, promoting sediment deposition. At the same time, it provides mechanical anchoring points for plant roots. The roots wrap around the protrusion structure to form a "biological-mechanical" composite stabilizing layer, further enhancing the scour resistance and ecological integration of the composite revetment pile body.

[0018] Preferably, the bottom end of the composite revetment pile body is fixedly connected to a bottom anchor block, and the bottom end of the bottom anchor block is fixedly connected to a uniformly distributed bottom anchor cone.

[0019] By adopting the above technical solution, the bottom anchoring block and the bottom anchoring cone work together to expand the contact area between the bottom of the composite revetment pile and the riverbed soil. The bottom anchoring cone penetrates the soil to form a embedding effect. In scenarios with rapid water flow or soft riverbed soil, the overturning resistance of the composite revetment pile is significantly improved, and the safety of the project is enhanced.

[0020] Preferably, the top of the composite revetment pile body has two symmetrical lifting rings.

[0021] By adopting the above technical solution, the lifting ring is pre-embedded in the main body of the composite revetment pile, which facilitates the lifting operation of the main body of the composite revetment pile during prefabrication, transportation and construction, improves construction efficiency, avoids damage to the pile body caused by traditional manual handling, and the lifting ring is integrated with the main structure of the composite revetment pile, so as not to affect the ecological function and structural strength of the top of the main body of the composite revetment pile.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This type of concrete ecological revetment pile utilizes a three-layer composite structure and ecological guidance components in synergy. A high-strength concrete core layer with embedded steel reinforcement provides structural strength. The first filler in the self-healing concrete layer enables self-repair of cracks, while the second filler in the porous recycled concrete layer creates a suitable environment for plant growth. The top and bottom nutrient soil layers within the pre-reserved cavity of the ecological guidance components are connected to honeycomb-distributed ecological pores via a polymer fiber mesh. Combined with a biocompatible coating on the inner wall of the ecological pores, this enhances vegetation survival rates. Furthermore, plant roots can grow laterally through the ecological pores, intertwining with the root systems of adjacent composite revetment piles to form a network structure, thus strengthening overall stability. The T-shaped connecting blocks and T-shaped connecting grooves, along with the barbed protrusions, form a three-dimensional anchoring system. The bottom anchoring blocks and bottom anchoring cones enhance anti-overturning capabilities, and the lifting ring facilitates construction. Overall, this design combines structural stability, ecological functionality, and durability, solving the problems of insufficient durability and difficulty in balancing strength and ecology in traditional revetment technologies.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A concrete ecological revetment pile, referring to Figure 1 , Figure 3 and Figure 4 The system includes a composite revetment pile body 1, which is a three-layer composite structure. From the inside out, it consists of a high-strength concrete core layer 101, a self-healing concrete layer 103, and a porous recycled concrete layer 105. A steel reinforcement skeleton 102 is embedded within the high-strength concrete core layer 101. The self-healing concrete layer 103 is filled with a first filler 104, and the porous recycled concrete layer 105 is filled with a second filler 106. The steel reinforcement skeleton 102 is made of HRB400 grade threaded steel. The first filler 104 is a mixture of Bacillus pasteurellosis and calcium carbonate precursors, and the second filler 106 is waste ceramic particles and highly absorbent materials. The resin mixture and the steel reinforcement skeleton 102, made of HRB400 grade threaded steel, enhance the tensile and compressive strength of the composite revetment pile body 1, working synergistically with the high-strength concrete core layer 101 to resist the impact of water flow. The mixture of Pasteurella multocida and calcium carbonate precursors in the self-healing concrete layer 103 activates a mineralization reaction when micro-cracks appear in the composite revetment pile body 1, generating calcium carbonate crystals to fill the cracks, achieving self-healing and extending the service life of the composite revetment pile body 1. The mixture of waste ceramic particles and highly absorbent resin in the porous recycled concrete layer 105 increases porosity and maintains soil moisture, providing a good foundation for vegetation growth.

[0033] Reference Figure 1 , Figure 3 and Figure 4The composite revetment pile body 1 has an ecological guidance component 2 inside. The ecological guidance component 2 includes a reserved cavity 201 at the top of the composite revetment pile body 1. A polymer fiber mesh 205 is fixedly connected to the inner wall of the reserved cavity 201. Ecological boards 202 are embedded on both sides of the composite revetment pile body 1. Each ecological board 202 has multiple ecological holes 203 on its inner wall. The multiple ecological holes 203 are arranged in a honeycomb pattern inside the ecological board 202. The inner wall of each ecological hole 203 is coated with a biocompatible coating 204. The multiple ecological holes 203 are connected to the reserved cavity 201. The top of the reserved cavity 201 is filled with a top nutrient soil layer 206, and the bottom of the reserved cavity 201 is filled with a bottom nutrient soil layer 207. The reserved cavity 201 is filled with the top nutrient soil layer 206 and the bottom nutrient soil layer 207, which are for... The surface plants provide a long-lasting nutrient supply, the top nutrient soil layer 206 collects rainwater or surface water, and the bottom nutrient soil layer 207 is connected to the ecological holes 203, forming a vertically connected water and nutrient transport channel, which improves the survival rate of vegetation and is especially suitable for the growth needs of plants in areas with fluctuating water levels. The polymer fiber net 205 is located between the top nutrient soil layer 206 and the bottom nutrient soil layer 207, and is located above the ecological board 202. The polymer fiber net 205 is located between the top nutrient soil layer 206 and the bottom nutrient soil layer 207, and is set above the ecological board 202. It can effectively prevent fallen leaves, mud and other debris from entering the ecological holes 203, avoiding blockage of the holes, while allowing water and nutrients to permeate. While ensuring the unobstructed flow of the ecological holes 203, it maintains the stability of the plant root growth environment.

[0034] Example 2: A concrete ecological revetment pile, referring to Figure 1 and Figure 2 Based on the same concept as Embodiment 1 above, this embodiment proposes that the composite revetment pile body 1 is provided with a connecting component 3 on its exterior. The connecting component 3 includes two T-shaped connecting blocks 301 fixedly connected to one side of the composite revetment pile body 1, and two T-shaped connecting grooves 302 are opened on the other side of the composite revetment pile body 1. The dimensions of the T-shaped connecting blocks 301 and the T-shaped connecting grooves 302 are matched. The T-shaped connecting blocks 301 and the T-shaped connecting grooves 302 of the connecting component 3 are matched in size, so that the adjacent composite revetment pile bodies 1 form a mechanical interlocking structure, which enhances the overall rigidity of the revetment. Together with the steel reinforcement skeleton 102 inside the composite revetment pile body 1 and the external barbed protrusions 4, a three-dimensional anchoring system is formed, which effectively resists the scouring force of water flow and improves the overall stability of the revetment project.

[0035] Reference Figure 1 and Figure 2The outer surface of the composite revetment pile body 1 is fixedly connected with uniformly distributed barbed protrusions 4. These protrusions increase the frictional resistance between the composite revetment pile body 1 and the surrounding soil and water flow. When water flows through, a turbulent zone is formed behind the protrusions, promoting sediment deposition. Simultaneously, they provide mechanical anchoring points for plant roots. The roots entwine around the protrusion structure to form a "biological-mechanical" composite stabilizing layer, further enhancing the erosion resistance and ecological integration of the composite revetment pile body 1. The bottom end of the composite revetment pile body 1 is fixedly connected with a bottom anchoring block 5. The bottom end of the bottom anchoring block 5 is fixedly connected with uniformly distributed bottom anchoring cones 6. The bottom anchoring block 5 and the bottom anchoring cones 6 work together... The design expands the contact area between the bottom of the composite revetment pile body 1 and the riverbed soil. The bottom anchoring cone 6 penetrates the soil to form a embedding effect, which significantly improves the overturning resistance of the composite revetment pile body 1 and enhances the safety of the project in scenarios with rapid water flow or loose riverbed soil. Two symmetrical lifting rings 7 are opened at the top of the composite revetment pile body 1. The lifting rings 7 are pre-embedded in the composite revetment pile body 1, which facilitates the lifting operation of the composite revetment pile body 1 during prefabrication, transportation and construction, improves construction efficiency and avoids damage to the pile body caused by traditional manual handling. At the same time, the lifting rings 7 are integrated with the structure of the composite revetment pile body 1 and do not affect the ecological function and structural strength of the top of the composite revetment pile body 1.

[0036] The implementation principle of this application embodiment is as follows: the prefabricated composite revetment pile body 1 is transported to the site through the lifting ring 7 pre-embedded in the top of the high-strength concrete core layer 101. The composite revetment pile body 1 is vertically driven into the riverbed using a hydraulic vibratory hammer. The bottom anchoring block 5 and the bottom anchoring cone 6 penetrate the soil, expanding the contact area between the composite revetment pile body 1 and the riverbed, forming mechanical embedment to resist the overturning of the composite revetment pile body 1. After the composite revetment pile body 1 is driven in, adjacent composite revetment pile bodies 1 are spliced ​​through the mechanical interlocking of the T-shaped connecting block 301 and the T-shaped connecting groove 302 of the connecting component 3. In conjunction with the barbed protrusions 4 evenly distributed on the surface of the composite revetment pile body 1, a turbulent zone is formed behind the protrusions under the action of water flow, promoting sediment deposition and enhancing the overall rigidity and scour resistance between the composite revetment pile bodies 1. In terms of structural function, the HRB400 grade threaded steel reinforcement cage 102 in the high-strength concrete core layer 101 bears the main tensile and compressive loads, and works in conjunction with the three-layer composite structure inside the composite revetment pile body 1 to resist the impact of water flow; when microcracks appear in the composite revetment pile body 1, the first filler 104 in the self-healing concrete layer 103 is activated by water, and produces calcium carbonate crystals to fill the cracks, thus achieving self-repair. The second filler 106 in the porous recycled concrete layer 105 forms a structure with a certain porosity, providing growth space for plant roots on the one hand, and maintaining soil moisture through super absorbent resin on the other. In the ecological guidance component 2, the top nutrient soil layer 206 in the reserved cavity 201 collects rainwater, and the bottom nutrient soil layer 207 is connected to the honeycomb-shaped ecological holes 203. The polymer fiber mesh 205 blocks debris from entering the ecological holes 203 while allowing water to permeate. The biocompatible coating 204 on the inner wall of the ecological holes 203 promotes the chemical bonding between the roots and the concrete. The plant roots grow laterally through the ecological holes 203 and intertwine with the plant roots in the adjacent composite revetment pile body 1 to form a network structure. Combined with the barbed protrusions 4 providing mechanical anchoring points for the roots, the overall stability of the revetment is further enhanced. This design achieves the organic unity of structural strength, ecological function and durability of the revetment project through the synergistic effect of "structural support-self-repair-ecological cultivation-three-dimensional anchoring".
