Description

Technical Field

[0001] This invention belongs to the field of ecological revetment technology, and specifically relates to a construction method for ecological revetment components. Background Technology

[0002] Ecological bank protection refers to a type of riverbank protection that uses plants or a combination of plants and civil engineering to prevent riverbank collapse, allow river water and soil to permeate each other, enhance the river's self-purification capacity, and create a certain natural landscape effect.

[0003] In addition to using traditional rigid materials such as masonry and concrete, the protection of river and lake banks in my country is increasingly adopting green concrete ecological protection technology. While protecting the stability of the shoreline and slope, it also re-establishes the connection between the water and the shore ecosystem, enabling various organisms to survive and reproduce on the protected shore, maintaining the integrity of the shore system and beautifying the shore landscape.

[0004] Currently, the most commonly used protective components are slope-type structures above waterfronts, predominantly hexagonal in shape. However, these components have poor inter-connectivity and are prone to sliding on the slopes of the revetment. To address this technical problem, a utility model patent entitled "Interlocking Composite Ecological Concrete Component" (Authorization Announcement No.: CN202157303U) has been disclosed. This interlocking composite ecological concrete component is suitable for waterfront slope protection, toe protection, and bottom protection requirements. Under the premise of safety and protection, it can better restore the natural, harmonious, and aesthetically pleasing ecological environment of the waterfront.

[0005] In existing technologies, filler material, consisting of crushed stone or pebble aggregate with a particle size of 30-40mm, is placed inside an I-shaped concrete frame. To enhance the water-blocking and protective function of the revetment, the ecological revetment components are often quite tall. However, when these components are lowered onto the sloping slope, they are prone to tipping over. Interlocking ecological revetment components also fail to adequately address these technical problems. Summary of the Invention

[0006] The purpose of this invention is to solve the aforementioned technical problems in the prior art and provide a construction method for ecological revetment components. This method can limit the bottom and sides of the ecological revetment components when they are hoisted onto the slope, ensuring that the components are positioned in the designated locations and preventing them from tipping over or moving. This facilitates the rapid filling of sand and gravel into the cavity two later. Simultaneously, the ecological revetment components can be applied to concrete walls one and two, forming an overall structure with excellent water-blocking and protective functions. Furthermore, the gaps between the sand and gravel filling the cavity two allow for the appropriate filling of soil into the backfill layer, providing rooting space for plants. Under the premise of safety and protection, this method can better restore the natural, harmonious, and aesthetically pleasing ecological environment of the revetment.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A construction method for an ecological revetment component, characterized by comprising the following steps:

[0009] a. According to the construction drawings, pour concrete on the slope to form a sloping concrete bottom foundation, then pour concrete at the bottom of the concrete bottom foundation to form concrete wall one, and then pour concrete at the top of the concrete bottom foundation to form concrete wall two.

[0010] b. Install supporting components: Pour concrete on the concrete bottom foundation to form a concrete fixed foundation. The inclination of the concrete fixed foundation is consistent with the inclination of the concrete bottom foundation. The supporting components are set in the concrete fixed foundation and extend beyond the top surface of the concrete fixed foundation by a set length. The design distance is maintained between two adjacent supporting components. Then, concrete is filled into the cavity of the supporting component to form a reinforcement layer.

[0011] c. Installing ecological revetment components: The ecological revetment components are concrete components with a through-cavity II. The ecological revetment components are hoisted onto the concrete fixed foundation, with one support component corresponding to one ecological revetment component. At the same time, the support components are set in the cavity II. Then, the ecological revetment components are fixedly connected to the concrete wall II.

[0012] d. Pour concrete into cavity two to form a concrete connection layer. The supporting components are placed in the concrete connection layer, so that the supporting components and the ecological revetment components are firmly connected.

[0013] e. Fill the cavity with sand and gravel, which are supported on the concrete bonding layer to form a backfill layer.

[0014] f. Set up formwork 1 in the area between concrete wall 1 and ecological revetment components, fill the area formed by formwork 1 with sand and gravel, and then fill the area with concrete to connect the concrete and sand and gravel into an integral structure to form sand and gravel support layer 1, and then remove formwork 1.

[0015] g. Set up formwork 2 in the area between concrete wall 2 and ecological revetment components, fill the area formed by formwork 2 with sand and gravel, and then fill the area with concrete to connect the concrete and sand and gravel into an integral structure to form sand and gravel support layer 2, and then remove formwork 2.

[0016] h. Based on the height of the concrete wall, backfill the slope with soil and compact it. Then lay blocks on the soil and install guardrails on the soil.

[0017] Furthermore, a threaded post 1 is installed in the concrete bottom foundation, perpendicular to the concrete bottom foundation. After the concrete bottom foundation has cured, a connector 1 is fixed on the supporting member. The connector 1 is L-shaped, and two connectors 1 are symmetrically welded to the inner wall of the cavity 1 of the supporting member. The connector 1 is then placed in the designated position on the concrete bottom foundation. Then, a connector 2 is installed between the connectors 1 of two adjacent supporting members. The connector 2 has a slot and a through hole 1. The slot is used to lock the connector 1, while the threaded post 1 passes through the through hole 1. The connector 2 is supported on the concrete bottom foundation. Then, a nut 1 is screwed into the threaded post 1, and the nut 1 is locked onto the top surface of the connector 2.

[0018] Furthermore, after nut one is tightened, apply anti-rust oil to the surfaces of connector one, connector two, and support components.

[0019] Furthermore, after the concrete foundation is completed, the length of the supporting components extending beyond the top surface of the concrete foundation is 10-15cm.

[0020] Furthermore, a threaded column 2 is installed in the concrete wall 2, and a connector 3 is installed on the threaded column 2. The threaded column 2 passes through the through hole 2 of the connector 3, and then a nut 2 is screwed into the threaded column 2. The nut 2 is locked onto the connector 3, and the connector 3 is fixed to the concrete wall 2. Then, a connector 4 is installed on the ecological revetment component. After the ecological revetment component is hoisted and placed, the connector 4 and the connector 3 come into contact, and then the connector 4 and the connector 3 are fixedly connected.

[0021] Furthermore, connector four includes a plate, a limiting block, and a connecting column. The limiting block and the connecting column are welded onto the plate. The ecological revetment component is provided with limiting hole one and limiting hole two. When connector four is installed, connector four is placed into cavity two, and then the limiting block is embedded into limiting hole one. At the same time, the connecting column is passed through limiting hole two. The plate is attached to the inner wall of the ecological revetment component, and then the connecting column and connector three are welded together.

[0022] Furthermore, after step c is completed, water is injected into cavity two of the ecological revetment component to moisten the inner wall of the ecological revetment component, and then concrete is poured into cavity two.

[0023] Furthermore, the distance between the top surface of the concrete connection layer and the top surface of the concrete fixed foundation is L1, and the distance between the top surface of the support member and the top surface of the concrete fixed foundation is L2, with L1 being 3-5cm longer than L2.

[0024] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0025] (1) This invention uses a concrete fixed foundation to fix the supporting components. At this time, the supporting components protrude a certain length from the top surface of the concrete fixed foundation. The exposed supporting components are set in the cavity two of the ecological revetment component. Concrete is used to firmly connect the supporting components and the ecological revetment component, thereby connecting the concrete fixed foundation, the supporting components, and the ecological revetment component into an integral structure, which limits the bottom of the ecological revetment component when it is hoisted onto the slope; and the ecological revetment component is fixedly connected to the concrete wall two, which limits the side of the ecological revetment component when it is hoisted onto the slope. This ensures that the ecological revetment component is positioned in the set position and will not tilt or move. It is suitable for tall and heavy concrete ecological revetment components.

[0026] Furthermore, concrete ecological revetment components are relatively heavy. To improve safety, concrete and gravel are laid in the area between concrete wall one and the ecological revetment components, forming a monolithic structure to create gravel support layer one. Similarly, concrete and gravel are laid in the area between concrete wall two and the ecological revetment components, forming gravel support layer two. By applying the ecological revetment components to concrete wall one and concrete wall two, the resulting integrated structure provides excellent water-retaining and protective functions.

[0027] (2) Based on the technical solution of stable fixing of ecological revetment components, this invention can quickly fill the cavity 2 with sand and gravel, which is supported on the concrete connecting layer to form a backfill layer with gaps. Moreover, sand and gravel can be filled into all ecological revetment components layer by layer, and the particle size of the sand and gravel gradually increases from bottom to top within the same ecological revetment component. Soil can be appropriately added to the backfill layer to provide root space for plants. Under the premise of protection and safety, the natural, harmonious, and beautiful ecological environment of the ecological revetment can be better restored. Attached Figure Description

Detailed Implementation

[0045] like Figures 1 to 15 The diagram illustrates a construction method for an ecological revetment component according to the present invention, comprising the following steps:

[0046] a. According to the construction drawings, pour concrete on the slope protection to form a sloping concrete foundation 1 with an inclination angle of 10°. Install threaded post 4 perpendicular to the concrete foundation 1. Then pour concrete at the bottom of the concrete foundation 1 to form concrete wall 2. Next, pour concrete at the top of the concrete foundation 1 to form concrete wall 3. Install threaded post 5 within concrete wall 3. Concrete wall 2 and concrete wall 3 should remain vertical.

[0047] Considering that the supporting components 6 may move during the later pouring of concrete on the concrete foundation 1, causing the ecological revetment components to be misaligned, all supporting components 6 are fixed to the concrete foundation 1 to solve this technical problem. The specific solution is as follows: After the concrete foundation 1 has cured, connector 1-8 is fixed to the supporting components 6. Connector 1-8 is L-shaped, and two connector 1-8s are symmetrically welded to the inner wall of the cavity 7 of the supporting component 6. Connector 1-8 is then placed in its designated position on the concrete foundation 1. Connector 2-9 is then installed between connector 1-8s of adjacent supporting components 6. Connector 2-9 has a slot 10 and a through hole 11. The slot 10 is used to hold connector 1-8 in place, while threaded post 1-4 passes through the through hole 1-11. Connector 2-9 is supported on the concrete foundation 1. Nut 1-12 is then screwed into threaded post 1-4, and nut 1-12 is locked onto the top surface of connector 2-9. After nut 12 is tightened, apply anti-rust oil to the surfaces of connector 8, connector 9, and support member 6 to ensure effective connection of connector 8, connector 9, and support member 6. This ensures that all support members 6 are fixed in a row at their designated positions on the concrete foundation 1. When pouring concrete on the concrete foundation 1, the support members 6 will not move, preventing the later ecological revetment components from being misaligned.

[0048] b. Installing Support Component 6: Pour concrete on the concrete base 1 to form a fixed concrete foundation 13. The inclination of the fixed concrete foundation 13 is consistent with the inclination of the concrete base 1. The support component 6 is placed in the fixed concrete foundation 13 and extends beyond the top surface of the fixed concrete foundation 13 by a predetermined length. The length of the support component 6 extending beyond the top surface of the fixed concrete foundation 13 is 10-15cm, and this invention uses 10cm. A designed distance is maintained between adjacent support components 6. Then, concrete is filled into the cavity 7 of the support component 6 to form a reinforcement layer 14, increasing the strength of the support component 6 and preventing its deformation. This allows the support component 6 to be connected to the ecological revetment component through the concrete.

[0049] c. Installation of Ecological Revetment Component 15: The ecological revetment component 15 is a concrete component made of C30 concrete. It has a through-cavity 16. The height of the ecological revetment component 15 is designed to be 250cm. The ecological revetment component 15 is hoisted onto the concrete fixed foundation 13. One support component 6 corresponds to one ecological revetment component 15, and the support component 6 is set in the cavity 16.

[0050] The ecological revetment component 15 is fixedly connected to the concrete wall 2 3. Specifically, a connector 3 22 is installed on the threaded post 2 5, passing through the through hole 2 of the connector 3 22. Then, a nut 23 is screwed into the threaded post 2 5, locking the connector 3 22 and fixing it to the concrete wall 2 3. Next, a connector 4 29 is installed on the ecological revetment component 15. After the ecological revetment component 15 is hoisted down, connector 4 29 and connector 3 22 come into contact, and then the connector 4 29 and connector 3 22 are fixedly connected. The connector 4 29 of this invention includes a plate 17, a limiting block 18, and a connecting post 19. The limiting block 18 and the connecting post 19 are welded to the plate 17. The ecological revetment component 15 is provided with a limiting hole 1 20 and a limiting hole 21. When installing connector 4 29, insert connector 4 29 into cavity 2 16, then embed the limiting block 18 into limiting hole 1 20, and simultaneously pass the connecting column 19 through limiting hole 2 21. The plate 17 is attached to the inner wall of the ecological revetment component 15, and then the connecting column 19 and connector 3 22 are welded together. This method can fix the ecological revetment component 15 to the concrete wall 2 3 one by one, and the fixing node is on the outside of the ecological revetment component 15, which facilitates welding operations. Moreover, this method causes less damage to the ecological revetment component 15.

[0051] After step c is completed, water is injected into cavity 16 of the ecological revetment component 15 to moisten the inner wall of the ecological revetment component 15. Then concrete is poured into cavity 16 to increase the fluidity of the concrete in the later stage.

[0052] d. Concrete is poured into cavity 16 to form a concrete connection layer 24. The support member 6 is placed in the concrete connection layer 24, so that the support member 6 and the ecological revetment member 15 are firmly connected. The distance between the top surface of the concrete connection layer 24 and the top surface of the concrete fixed foundation 13 is L1, and the distance between the top surface of the support member 6 and the top surface of the concrete fixed foundation 13 is L2. L1 is 3-5cm longer than L2. In this invention, L1 is 5cm longer than L2.

[0053] e. Fill the cavity 16 with sand and gravel, which are supported on the concrete connecting layer 24 to form the backfill layer 25. The particle size of the sand and gravel is 30-40mm.

[0054] f. Set up template 1 in the area between concrete wall 12 and ecological revetment component 15, fill the area formed by template 1 with sand and gravel, and fill the area with concrete to connect the concrete and sand and gravel into an integral structure to form sand and gravel support layer 26, and then remove template 1.

[0055] g. Set up formwork 2 in the area between concrete wall 2 3 and ecological revetment component 15, then fill the area formed by formwork 2 with sand and gravel, and then fill the area with concrete to connect the concrete and sand and gravel into an integral structure, forming sand and gravel support layer 27. Then remove formwork 2. At this time, the connecting column 19 of connector 4 29 and connector 3 22 are set in sand and gravel support layer 27, so that connector 4 29 and connector 3 22 are connected into an integral structure, which can protect connector 4 29 and connector 3 22.

[0056] h. Based on the height of concrete wall 23, backfill soil on the slope and compact it. Then lay blocks on the soil for pedestrians to walk on, and set up guardrails 28 on the soil for protection.

[0057] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
