Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic engineering, in particular to an assembled ecological cofferdam and a construction process thereof. BACKGROUND

[0002] In river regulation, soil and water conservation and slope protection engineering, ecological cofferdam is a common structure. Traditional ecological cofferdam or slope protection technology focuses on single physical protection function or simple vegetation restoration, which gradually exposes many limitations in actual application and long-term maintenance.

[0003] In the integration of ecological function and engineering structure, the existing technology is often fragmented. Common concrete block revetment or pure stone revetment has stable structure, but the surface is hardened, which blocks the natural exchange of soil and water, air, destroys the original riverbank ecological corridor, and makes it difficult for vegetation to grow naturally, resulting in a decrease in biodiversity. While some use direct soil covering and grass planting methods, although they are more ecological, the soil erosion resistance is weak, and water and soil loss is easily caused under the erosion of rainwater or water flow. The durability of the revetment structure is poor, and the ecological benefits are difficult to maintain for a long time. That is, the existing scheme is difficult to ensure the safety and stability of the project while achieving truly sustainable ecological restoration.

[0004] In terms of water resource management and utilization, the existing cofferdam design generally lacks intelligent and efficient integrated systems. Many projects rely on natural precipitation or external artificial irrigation to maintain slope vegetation, which is prone to withering in dry seasons, resulting in a loss of ecological function. Some structures with water storage facilities often lack effective automatic regulation and recycling mechanisms, either lacking sufficient water storage capacity or failing to discharge excess water in time during heavy rain, which may increase the seepage pressure inside the slope body, affecting stability, and failing to achieve water resource recycling and conservation, resulting in high maintenance and management costs.

[0005] In terms of construction efficiency and structural adaptability, traditional construction methods often require a large amount of site pouring or masonry, long construction period, and large site environmental disturbance, and the standardization of components is low. The anchoring or reinforcing method is mostly one-time implantation (such as precast piles or simple anchor rods), which cannot be adjusted according to actual geological conditions or stress changes after embedding. It lacks sufficient adaptability and anchoring force compensation ability for complex and variable foundation soil, which may pose a long-term safety risk to the entire cofferdam structure.

[0006] Therefore, it is an urgent need to develop a new type of ecological cofferdam structure that can deeply integrate ecological and engineering functions, has self-adaptive water cycle management capability, and can be quickly assembled and flexibly reinforced, to solve the above industry pain points.

Detailed Implementation

[0049] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0050] Example 1:

[0051] This invention provides a prefabricated ecological cofferdam, as shown in the attached figure. Figure 1 As shown, the cofferdam includes a slope 100 and a protective net 800. The protective net 800 is installed above the slope 100 near the river channel for personnel protection. The slope 100 serves as the load-bearing foundation of the entire cofferdam, providing a carrier for the installation of all functional components. Its sloping structure directly determines the protection angle and stability of the cofferdam. The modified slope surface can effectively disperse the impact pressure of the water flow and reduce the risk of soil erosion. The core function of the protective net 800 is personnel protection, preventing personnel from accidentally falling into the river channel during construction and subsequent maintenance. At the same time, it can also help block some floating debris from contacting the slope 100, reducing the impact damage of debris on the slope surface and components, and improving the safety of the cofferdam.

[0052] As attached Figure 2 As shown, the pad assembly 200 is set at the slope of the slope 100 to compact the slope surface; it includes a slope protection plate 201 set on the slope of the slope 100, with embedded grooves 202 equidistantly through the slope protection plate 201, and a mesh groove 203 arranged laterally on the slope protection plate 201. Slope protection bricks 204 are installed in the embedded grooves 202, and greening holes 205 are through the middle of the slope protection bricks 204. The slope protection board 201 compacts the slope surface, improving the overall integrity and flatness of the slope structure and preventing weathering and erosion caused by direct exposure of the slope soil. The equally spaced embedding grooves 202 on the board provide precise installation positioning for the slope protection bricks 204, while the horizontally set mesh grooves 203 provide channels for rainwater infiltration, irrigation water flow, and subsequent irrigation component 500 pipeline layout. The embedding grooves 202, through their equally spaced through-hole design, ensure that the slope protection bricks 204 are laid evenly, forming a stable overall structure with the slope protection board 201 and preventing the displacement of individual slope protection bricks 204. At the same time, the reserved installation gaps can accommodate minor soil settlement, improving the structural adaptability. The mesh grooves 203 can guide rainwater to quickly infiltrate to the lower planting soil layer 300, preventing rainwater from accumulating on the slope surface and forming runoff that erodes the slope. On the other hand, they provide space for the layout of the inclined pipes 502 and nozzles 503 of the irrigation component 500, ensuring that the irrigation water can accurately act on the green area above the planting soil layer 300. The slope protection brick 204 further enhances the slope compaction effect and disperses the external forces borne by the slope. The greening hole 205 that runs through the middle provides a carrier for ecological planting, allowing the roots of the green plants to penetrate the slope protection brick 204 and reach the lower planting soil layer 300, realizing the combination of engineering protection and ecological slope stabilization. The roots of the green plants can also further entwine the soil and improve the stability of the slope 100.

[0053] As attached Figure 3As shown, the planting soil layer 300 is located below the slope protection slab 201, and consists of a pebble layer 301, a fine soil layer 302, and a sand and gravel layer 303 arranged sequentially from top to bottom to provide an ecological planting foundation. The pebble layer 301 filters impurities in rainwater and irrigation water, preventing them from clogging the pores of the lower soil layer. Simultaneously, its larger particle spacing improves soil aeration and water permeability, providing sufficient oxygen for plant root respiration and mitigating the erosion of the lower fine soil layer 302 by water flow, thus protecting the planting foundation. The fine soil layer 302 serves as the core nutrient layer for plant growth. The first layer, rich in organic matter and nutrients needed for plant growth, provides a carrier for plant roots to attach to and absorb nutrients. Its fine particles can store an appropriate amount of water, balance soil moisture, and ensure water supply for plants during dry periods. The gravel layer 303 has larger particles and a loose structure, which is used to improve the drainage performance of the planting soil layer 300 and prevent rainwater or irrigation water from accumulating at the bottom of the fine soil layer 302, which can lead to root rot. At the same time, it can enhance the overall bearing capacity of the planting soil layer 300, prevent the upper soil from settling and deforming, and provide stable support for the entire planting soil layer 300.

[0054] As attached Figure 3 As shown, the water storage and drainage assembly 400 is installed inside the slope 100 to store water inside the slope 100 and discharge excess water when necessary. It includes a first water storage tank 401 located at the upper end inside the slope 100, a connecting pipe 402 equidistantly arranged on one side of the first water storage tank 401, a second water storage tank 403 arranged at the other end of the connecting pipe 402, and a drain pipe 404 equidistantly arranged on one side of the second water storage tank 403. The second water storage tank 403 serves to divert water and increase the water storage capacity of the entire water storage and drainage assembly 400.

[0055] One end of the connecting pipe 402 is located at two-thirds of the height of the first water storage tank 401, and the other end is connected to the side of the second water storage tank 403 to achieve water balance between the two water storage tanks. When the water volume of the first water storage tank 401 reaches two-thirds of the height (safe water storage threshold), the excess water flows into the second water storage tank 403 automatically through the connecting pipe 402 to prevent the water volume of the first water storage tank 401 from overflowing and causing the soil moisture content of the slope 100 to be too high, which may lead to softening and landslide.

[0056] One end of the drainage pipe 404 is located at two-thirds of the height on the other side of the second water storage tank 403, and the other end is connected to the river channel. It is used to discharge excess water and prevent excessive water volume in the two water storage tanks from causing excessive internal pressure in the slope 100. When the water volume in the second water storage tank 403 reaches two-thirds of the height, the excess water is automatically discharged back into the river channel through the drainage pipe 404 to realize water resource recycling and at the same time ensure the structural safety of the slope 100.

[0057] As attached Figure 3As shown, the irrigation component 500 is located at the middle interval of the pad assembly 200 and is used to irrigate the ecological planting environment; it includes a first water pump 501 located at the bottom of the inner cavity of the first water storage tank 401 and the second water storage tank 403. The output end of the first water pump 501 is equipped with an inclined pipe 502, which penetrates the slope 100 and the mesh trough 203 and is equipped with a nozzle 503. The nozzle 503 is disc-shaped and has spray holes equidistantly opened on the side. The first water pump 501 is used to pump water stored in the water storage tank and deliver it to the inclined pipe 502. Its installation at the bottom can maximize the use of water resources in the water storage tank and avoid water waste. At the same time, the stable pumping power ensures uniform pressure of irrigation water flow. The inclined pipe 502 is used to deliver irrigation water flow. Its inclined layout is adapted to the slope angle of the slope 100 and can accurately guide the water flow to the green area of ​​the slope. At the same time, the design of the through mesh trough 203 avoids the pipe from being exposed and damaged, and improves the service life of the pipe. The disc-shaped nozzle 503 can make the water flow cover a wider range.

[0058] As attached Figure 4 As shown, the pumping assembly 600 is located inside the slope 100 and below the storage and drainage assembly 400, and is used to pump water from the river to cooperate with the irrigation assembly 500. It includes a second pumping pump 602 installed in the second storage tank 403. The input end of the second pumping pump 602 is equipped with a pumping pipe 601, which is connected to the river. The output end of the second pumping pump 602 is equipped with a water delivery pipe 603, which is connected to the first storage tank 401, and the connection port is located at three-quarters of the height of the side wall of the first storage tank 401. The second pump 602 can draw river water through the pumping pipe 601 and transport it to the delivery pipe 603. It is set in the second water storage tank 403, which can use the protection of the water storage tank to prevent the pump from directly contacting the soil and causing damage. At the same time, it is close to the lower side of the river, which shortens the laying distance of the pumping pipe 601 and improves the pumping efficiency. The delivery pipe 603 is used to transport the pumped river water to the first water storage tank 401. The connection port is set at three-quarters of the height, which can prevent the water flow from directly impacting the bottom of the water storage tank and causing impurities to surge. At the same time, it reserves a certain water storage buffer space for the first water storage tank 401 to ensure water storage safety.

[0059] As attached Figure 5 As shown, the reinforcement component 700 is disposed on both sides of the pad assembly 200 and the protective net 800 to reinforce the pad assembly 200 and the protective net 800; it includes a rod 701, an anchor 702, and a drive component 703; the rod 701 is inserted into the soil of the slope 100; the anchor 702 is disposed in the middle of the rod 701 and is used to open and anchor in the soil to increase the stability of the rod 701 in the soil; the drive component 703 is inserted into the inner cavity of the rod 701 and is used to drive the anchor 702 to open and close by rotation.

[0060] As attached Figure 6As shown, the pole 701 also includes a pole body 7011. An auxiliary tongue 7012 is fixedly installed on the upper outer side of the pole body 7011. Fixing nails 7013 are fixedly installed on both sides of the auxiliary tongue 7012. A first internal thread 7014 is formed on the upper part of the inner cavity of the pole body 7011. A slot 7015 is formed on the middle of the outer side of the pole body 7011. A nail bottom 7016 is fixedly installed on the bottom of the pole body 7011. The pole body 7011 is inserted into the soil of the slope 100 and can directly withstand the lateral pressure of the protective net 800, transferring the pressure to the deep soil and improving the structural stability. The auxiliary tongue 7012, together with the fixing nails 7013, forms a multi-point fixation after the fixing nails 7013 are inserted into the surface soil, further improving the connection between the auxiliary tongue 7012 and the slope 100, and assisting the pole body 7011 in resisting lateral tension and preventing the pole body 7011 from shifting. The opening 7015 provides telescopic space for the support rod 7024 and the anchor plate 7025, allowing the anchor plate 7025 to extend and open from the opening 7015 under the action of the drive component 703, achieving an anchoring connection with the deep soil. The nail bottom 7016 has a pointed design, which facilitates the insertion of the rod 7011 into the deep soil, while enhancing the load-bearing capacity of the bottom of the rod 7011, preventing the rod 7011 from sinking after insertion, and improving the overall stability of the rod 7011.

[0061] As attached Figure 6 and attached Figure 7As shown, the anchor 702 also includes a movable ring 7021 movably disposed in the lower part of the inner cavity of the rod 7011. The inner side of the movable ring 7021 is provided with a second internal thread 7022. An outer fixing block 7023 is provided on the outer side of the movable ring 7021 and located inside the opening 7015. A support rod 7024 is movably disposed on the outer side of the outer fixing block 7023 via a pin. An anchor plate 7025 is installed on the other end of the support rod 7024 via a pin and a lug. A fixing ring 7026 is fixedly installed in the middle of the inner cavity of the rod 7011. A hinge plate 7027 is fixedly installed on the outer side of the lower end of the fixing ring 7026 and on the inner side of the upper end of the opening 7015. The hinge plate 7027 is fixedly connected to the inner side of the anchor plate 7025. The second internal thread 7022 on the inner side of the moving ring 7021 engages with the second external thread 7034 at the lower end of the drive rod 7031, allowing it to move axially along the rod body 7011 when the drive rod 7031 rotates. This movement drives the support rod 7024 to extend and retract, providing power for the opening of the anchor plate 7025. The axial movement of the moving ring 7021 is converted into the radial extension and retraction of the support rod 7024 by the external fixing block 7023, while limiting the movement trajectory of the support rod 7024 to ensure precise extension and retraction. The support rod 7024 is used to transmit the power of the moving ring 7021, pushing the anchor plate 7025 to open. Its movable connection design can adapt to different opening angles of the anchor plate 7025, improving the adaptability of the anchor 702. Anchor plate 7025 is connected to support rod 7024 via pin and lug, and is fixed to hinge plate 7027 on its inner side. Under the push of support rod 7024, it can open outward around hinge plate 7027, embedding itself into deep soil to form a large-area force-bearing surface, significantly improving the friction and anchoring force between anchor 702 and soil, and preventing rod 701 from being pulled out. Fixing ring 7026 is fixed in the middle of the inner cavity of rod 7011, providing an installation carrier for hinge plate 7027, while limiting the upper limit of movement of moving ring 7021, preventing excessive upward movement of moving ring 7021 that could damage anchor plate 7025 due to excessive opening angle; hinge plate 7027 provides a rotation fulcrum for anchor plate 7025, allowing anchor plate 7025 to open or close smoothly, while also enhancing the connection between anchor plate 7025 and rod 7011, preventing anchor plate 7025 from falling off under stress.

[0062] As attached Figure 6 As shown, the driving component 703 also includes a driving rod 7031, which is inserted into the inner cavity of the rod body 7011. The upper outer side of the driving rod 7031 has a first external thread 7032, which engages with a first internal thread 7014 within the inner cavity of the rod body 7011. A handle 7033 is fixedly mounted on the top of the driving rod 7031, and a second external thread 7034 is provided on the lower outer side of the driving rod 7031, which engages with a second internal thread 7022 on the inner side of the moving ring 7021. The second internal thread 7022 engages with the second internal thread 7022 of the moving ring 7021, converting the rotational motion of the driving rod 7031 into the axial movement of the moving ring 7021, providing precise power output for the opening of the anchor plate 7025.

[0073] The drive rod 7031 is inserted into the inner cavity of the rod body 7011, so that the first external thread 7032 at the upper end of the drive rod 7031 engages with the first internal thread 7014 of the rod body 7011, and the second external thread 7034 at the lower end of the drive rod 7031 engages with the second internal thread 7022 of the moving ring 7021; the operator rotates the handle 7033 at the top of the drive rod 7031, causing the drive rod 7031 to rotate axially along the rod body 7011 and move upward, thereby causing the moving ring 7021 to move upward along the inner cavity of the rod body 7011; during the upward movement of the moving ring 7021, the support rod 7024 is pushed outward by the outer fixing block 7023, and the support rod 7024 extends outward. The pole 7024 drives the anchor plate 7025 to open outward around the hinge plate 7027 until the anchor plate 7025 is fully embedded in the deep soil, completing the anchoring and enhancing the stability of the pole 701 in the soil; the protective net 800 is laid on the slope 100 above the river channel, and the edge of the protective net 800 is fixedly connected to the poles 701 that have been installed on both sides to ensure a firm connection, thereby reinforcing the protective net 800 through the stability of the poles 701; at the same time, the positional relationship between the pad assembly 200 and the pole 701 is checked to ensure that the pole 701 provides lateral support to the pad assembly 200, thereby reinforcing the pad assembly 200.

After the poles 701 of the reinforcement components 700 are installed, lay the protective net 800 at the preset position above the slope 100 near the river channel, adjust the flatness of the protective net 800, and then firmly connect the edge of the protective net 800 to the poles 701 on both sides. The protective net 800 is fixed by the stable structure of the reinforcement components 700, thus completing the installation and reinforcement of the protective net 800.

[0075] S9. Perform system debugging, start the second water pump 602 and the first water pump 501, and check the connectivity of the water pumping and water delivery pipes 603 and whether the irrigation, storage and drainage functions are normal.

[0076] The specific implementation process is as follows:

[0077] During the rainy season: Rainwater falls on the surface of the slope 100 and seeps into the planting soil layer 300 through the mesh grooves 203 of the slope protection board 201. Some rainwater further seeps into the first water storage tank 401 and the second water storage tank 403 inside the slope 100 to collect rainwater. When the water volume of the first water storage tank 401 reaches two-thirds of its height, the excess rainwater flows into the second water storage tank 403 through the connecting pipe 402. When the water volume of the second water storage tank 403 reaches two-thirds of its height, the excess rainwater is discharged back into the river through the drainage pipe 404 to avoid excessive soil moisture content on the slope 100 and to achieve rainwater recycling.

[0078] During the dry season: The second pump 602 of the pumping assembly 600 is activated to draw water from the river through the pumping pipe 601 and transport it to the first water storage tank 401 through the water conveying pipe 603. When the water volume in the first water storage tank 401 reaches three-quarters of its height, pumping is stopped or the water is diverted to the second water storage tank 403 through the connecting pipe 402. The first pump 501 of the irrigation assembly 500 is activated to transport the stored water in the first water storage tank 401 and the second water storage tank 403 to the sprinkler head 503 through the inclined pipe 502. The sprinkler head 503 sprays the water evenly onto the green area to achieve irrigation. Excess irrigation water seeps into the planting soil layer 300 through the mesh trough 203 and then replenishes the water storage tank, forming a water resource cycle to ensure the growth of green plants.

[0079] The reinforcing component 700 has rods 701 installed on both sides of the base plate assembly 200 and the protective net 800. It achieves its own stability through deep anchoring of the anchors 702, thereby providing lateral support for the base plate assembly 200 and preventing the base plate assembly 200 from shifting when impacted by water flow or soil settlement. At the same time, through the fixed connection with the protective net 800, it ensures the installation stability of the protective net 800 and avoids damage to the protective net 800 by water flow or external forces. The stability of the reinforcing component 700 provides structural protection for the entire cofferdam system and ensures that other components can function normally.

[0080] The slope 100 provides the installation foundation for all components. The pad assembly 200 and the planting soil layer 300 achieve slope compaction and ecological planting. The reinforcement assembly 700 ensures the stability of the pad assembly 200 and the protective net 800, and the protective net 800 provides personnel safety protection. The water storage and drainage assembly 400 realizes water resource storage and discharge. The pumping assembly 600 replenishes the water source for the water storage and drainage assembly 400. The irrigation assembly 500 uses the stored water of the water storage and drainage assembly 400 for ecological irrigation. All components support each other and work together to ultimately achieve the functions of slope protection, ecological sustainability and safe use of the cofferdam.

Connect a water delivery pipe to the output end of the second pumping pump, so that the end of the water delivery pipe away from the second pumping pump connects to the first water storage tank, and the connection port is located at three-quarters of the height of the side wall of the first water storage tank, for pumping river water to cooperate with the irrigation assembly. S7. Install reinforcement components on both sides of the pad assembly and both sides of the protective net to reinforce the pad assembly and the protective net. Insert the rod body into the slope soil so that the nail bottom of the rod body is embedded deep into the soil. The auxiliary tongue on the outer side of the upper part of the rod body fits against the slope surface, and the upper part of the rod body is further fixed by the fixing nails on both sides of the auxiliary tongue. Insert the drive rod into the inner cavity of the rod body so that the first external thread on the outer side of the upper end of the drive rod engages with the first internal thread on the upper part of the inner cavity of the rod body, and the second external thread on the outer side of the lower end of the drive rod engages with the second internal thread on the inner side of the moving ring. Rotate the handle at the top of the drive rod to drive the moving ring to move upward along the inner cavity of the rod body, so that the support rod pushes the anchor plate to open outward around the hinge plate, realizing the opening and anchoring of the anchor plate in the soil and increasing the stability of the rod in the soil. S8. Install the protective netting, fix the protective netting above the slope where it is close to the river, and connect and fix it to the poles of the reinforcement components on both sides. S9. Perform system debugging, start the second and first water pumps, and check the connectivity of the water pumping and conveying pipelines and whether the irrigation, storage and drainage functions are normal.
