Description

Technical Field

[0001] This utility model relates to the field of revetment structure technology, and in particular to a revetment for the recycling of old ground. Background Technology

[0002] With the acceleration of urbanization and infrastructure upgrades, a large number of old concrete blocks are being discarded due to demolition or renovation. Direct disposal not only wastes resources but may also cause environmental pollution. Meanwhile, traditional revetments, mostly constructed of reinforced concrete or stone, while possessing strong flood control capabilities, generally suffer from insufficient ecological function, poor landscape harmony, and low construction flexibility, making them ill-suited to the eco-friendly and sustainable demands of modern urban waterfront spaces. Furthermore, traditional revetments often exhibit insufficient stability or high maintenance costs when dealing with dynamic loads such as water level fluctuations and ship impacts due to their simple structure.

[0003] Chinese patents disclose a revetment (publication number: CN 203256679 U) comprising a crushed stone layer, a fine stone concrete layer, wire mesh, non-woven fabric, a cement mortar bonding layer, a pebble layer, and a concrete retaining wall. The crushed stone layer is 60-80mm thick, and a fine stone concrete layer with a thickness of 100-120mm is placed on top of the crushed stone layer. Wire mesh is placed in the middle of the fine stone concrete layer, and non-woven fabric is laid on top of the fine stone concrete layer. However, this type of revetment has problems such as insufficient ecological function, poor landscape coordination, low construction flexibility, limited impact resistance, and resource waste. Therefore, there is a need for a revetment that recycles old ground. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of insufficient ecological function, poor landscape coordination, low construction flexibility, limited impact resistance and resource waste that are common in traditional revetments in the prior art, and to propose a revetment for the recycling of old ground.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The utility model describes a revetment for the recycling of old ground, comprising a main revetment structure. The main revetment structure is characterized by being formed by mixing and casting old ground concrete blocks with cement-based cementitious materials. An ecological retaining wall module is provided on the water-facing side of the main revetment structure. The ecological retaining wall module is made of concrete blocks. A ground layer is provided on one side of the ecological retaining wall module, and a waterway is provided on the ground layer. By reusing old ground concrete blocks and combining them with cement-based cementitious materials to form the main revetment structure, the resource utilization of waste materials is realized, reducing construction waste generation. The independent ecological retaining wall module on the water-facing side of the revetment can be specifically adapted to the aquatic environment, improving the ecological adaptability and protective function of the revetment. The spatial layout between the ecological retaining wall module, the ground layer, and the waterway forms a natural transition from land to water, helping to achieve multi-functional integration of the revetment, including flood control, ecological restoration, and landscape coordination.

[0006] Preferably, the ecological retaining wall module is composed of multiple retaining units arranged sequentially and interconnected laterally. Each retaining unit has two coaxially corresponding drainage holes distributed on its sidewall. Decomposing the ecological retaining wall module into multiple independent and laterally connected retaining units facilitates construction, assembly, and subsequent maintenance, while also enhancing the structure's adaptability and flexibility. The coaxially corresponding drainage holes on the sidewalls of the retaining units promote lateral flow of water or gas, preventing localized water pressure buildup and improving the stability of the internal environment of the retaining wall. The drainage hole design enhances the interaction between the retaining wall and the surrounding water and soil, contributing to maintaining ecological balance.

[0007] Preferably, the retaining unit has a wedge-shaped structure at its bottom for embedding into the soil, and drainage grooves on both sides of its outer wall. The wedge-shaped structure at the bottom of the retaining unit allows for more effective embedding into the soil, enhancing the bond between the retaining wall and the foundation, and improving the overall resistance to sliding and overturning. The drainage grooves on both sides of the outer wall guide water flow out along the grooves, reducing the direct impact of water pressure on the sides of the retaining wall, while also helping to prevent soil erosion by water flow and enhancing the long-term stability of the retaining wall. This structural design enables the retaining unit to maintain structural strength while possessing good drainage and erosion resistance.

[0008] Preferably, the retaining unit is a long, hollow, elongated structure with a planting trough inside. The elongated, hollow structure of the retaining unit reduces its weight and construction difficulty, while also allowing for the utilization of internal space. The planting trough within the top cavity allows for the direct planting of aquatic plants or slope vegetation, enhancing the ecological function of the revetment and promoting biodiversity. The presence of the planting trough enables the retaining wall to not only provide protection but also participate in the construction of the ecosystem, improving the quality of the surrounding environment.

[0009] Preferably, the retaining unit is equipped with a floating anti-collision module on its top periphery. This floating anti-collision module effectively buffers direct impacts from external forces such as ships and floating objects, reducing the risk of structural damage. Its floating design allows it to move with water level changes, maintaining continuous anti-collision functionality and adapting to protection needs under different water level conditions. This module enhances the safety of the revetment, especially in navigable waterways or areas with frequent human activity, improving the revetment's durability and reliability.

[0010] Preferably, a permeable buffer layer is provided between the ecological retaining wall module and the ground layer, and the permeable buffer layer is composed of a composite of crushed stone and geotextile. The permeable buffer layer between the ecological retaining wall module and the ground layer can effectively regulate the water infiltration rate and prevent structural instability caused by rapid water accumulation or loss.

[0011] The composite structure of crushed stone and geotextile provides good permeability and prevents soil particles from being lost with water flow, thus maintaining the stability of the foundation. As a transition layer, this buffer layer reduces the hard contact between different materials, disperses stress concentration, and improves the overall structural coordination and durability of the revetment.

[0012] The advantages of this utility model are:

[0013] This application utilizes recycled revetment of old ground by mixing waste concrete blocks with cement-based cementitious materials to form the main structure, achieving resource utilization of construction waste and reducing environmental pollution and resource waste. The ecological retaining wall module is composed of multiple horizontally connected retaining units, which not only facilitates construction assembly and subsequent maintenance, but also enhances the gas exchange capacity between the water body and the interior of the retaining wall through the drainage hole design on the side wall, avoiding local water pressure accumulation and improving structural stability. The wedge-shaped structure at the bottom of the retaining unit allows it to be firmly embedded in the soil, enhancing its anti-slip ability, while the drainage channels on both sides of the outer wall effectively guide water flow out, reducing the risk of soil erosion. The design of the hollow top cavity and internal planting troughs enables the retaining wall to have vegetation planting function, promoting ecological restoration and landscape harmony. The floating anti-collision module on the top perimeter can buffer the impact of ships or floating objects, improving the safety and durability of the revetment. The permeable buffer layer between the ecological retaining wall module and the ground layer is composed of a composite of crushed stone and geotextile, which can regulate water infiltration, prevent soil loss, and disperse stress concentration, enhancing the overall structural stability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example

[0020] Please see Figure 1-3 As shown, a revetment for the recycling of old ground includes a main revetment structure 5. The main revetment structure 5 is characterized by being formed by mixing and casting old ground concrete blocks with cement-based cementitious materials. An ecological retaining wall module 4, made of concrete blocks, is provided on the water-facing side of the main revetment structure 5. A ground layer 1 is provided on one side of the ecological retaining wall module 4, and a waterway 11 is provided on the ground layer 1. By reusing old ground concrete blocks and combining them with cement-based cementitious materials to form the main revetment structure 5, the resource utilization of waste materials is realized, reducing construction waste generation. The independent ecological retaining wall module 4 on the water-facing side of the revetment can be specifically adapted to the aquatic environment, enhancing the ecological adaptability and protective function of the revetment. The spatial layout between the ecological retaining wall module 4, the ground layer 1, and the waterway 11 forms a natural transition from land to water, contributing to the multifunctional integration of the revetment, including flood control, ecological restoration, and landscape coordination.

[0021] In this embodiment, the ecological retaining wall module 4 is composed of multiple retaining units 10 arranged sequentially and interconnected laterally. Each retaining unit 10 has two coaxially corresponding drainage holes 7 distributed on its sidewall. Decomposing the ecological retaining wall module 4 into multiple independent and laterally connected retaining units 10 facilitates construction, assembly, and subsequent maintenance, while also enhancing the structure's adaptability and flexibility. The coaxially corresponding drainage holes 7 on the sidewalls of the retaining units 10 facilitate the lateral flow of water or gas, preventing localized water pressure buildup and improving the stability of the internal environment of the retaining wall. The design of the drainage holes 7 enhances the interaction between the retaining wall and the surrounding water and soil, contributing to maintaining ecological balance.

[0022] In this embodiment, the retaining unit 10 has a wedge-shaped structure 9 at its bottom for embedding into the soil, and drainage grooves 8 on both sides of its outer wall. The wedge-shaped structure 9 at the bottom of the retaining unit 10 can be more effectively embedded into the soil, enhancing the bonding force between the retaining wall and the foundation, and improving the overall resistance to sliding and overturning. The drainage grooves 8 on both sides of the outer wall can guide water flow out along the grooves, reducing the direct impact of water pressure on the sides of the retaining wall, while also helping to prevent soil erosion by water flow and enhancing the long-term stability of the retaining wall. This structural design enables the retaining unit 10 to maintain structural strength while possessing good drainage and erosion resistance.

[0023] In this embodiment, the retaining unit 10 is a long, hollow top cavity with a planting trough 6 inside. The long, hollow structure of the retaining unit 10 reduces its weight and construction difficulty, while also allowing for the utilization of internal space. The planting trough 6 inside the top cavity can be used directly to plant aquatic plants or slope vegetation, enhancing the ecological function of the revetment and promoting biodiversity. The presence of the planting trough 6 allows the retaining wall to not only provide protection but also participate in the construction of the ecosystem, improving the quality of the surrounding environment.

[0024] In this embodiment, a floating anti-collision module 3 is provided on the top periphery of the retaining unit 10. The floating anti-collision module 3 effectively buffers the direct impact of external forces such as ships and floating objects on the retaining wall, reducing the risk of structural damage. Its floating design allows it to float with changes in water level, maintaining the continuity of its anti-collision function and adapting to protection needs under different water level conditions. This module enhances the safety of the revetment, especially in navigable waterways 11 or areas with frequent human activity, improving the durability and reliability of the revetment.

[0025] In this embodiment, a permeable buffer layer 2 is provided between the ecological retaining wall module 4 and the ground layer 1. The permeable buffer layer 2 is composed of crushed stone and geotextile. The permeable buffer layer 2 between the ecological retaining wall module 4 and the ground layer 1 can effectively regulate the water infiltration rate and avoid structural instability caused by rapid water accumulation or loss.

[0026] The composite structure of crushed stone and geotextile provides good permeability and prevents soil particles from being lost with water flow, thus maintaining the stability of the foundation. As a transition layer, this buffer layer reduces the hard contact between different materials, disperses stress concentration, and improves the overall structural coordination and durability of the revetment.

[0027] The implementation principle of this embodiment is as follows:

[0028] Main structural stability: The main body of the revetment is made of old concrete blocks and cement-based cementitious materials. By utilizing the strength of the waste materials and the adhesiveness of the cementitious materials, a stable load-bearing foundation is formed to resist water erosion and foundation settlement.

[0029] Hydraulic regulation of ecological retaining wall module 4: Ecological retaining wall module 4 is composed of multiple horizontally connected retaining units 10. The drainage holes 7 on the side wall allow water and gas to flow laterally, avoiding local water pressure accumulation, while enhancing the interaction between the retaining wall and the surrounding water. The wedge-shaped structure 9 at the bottom is embedded in the soil to improve anti-sliding stability, while the drainage groove 8 on the outer wall guides water flow out, reducing the risk of soil erosion.

[0030] Vegetation restoration and landscape coordination: The hollow cavity at the top of the retaining unit 10 and the planting trough 6 provide growth space for vegetation. The roots of aquatic plants can stabilize the soil and protect the slope, absorb water pollutants, enhance the landscape effect, and promote the natural restoration of the ecosystem.

[0031] Impact Resistance and Safety Protection: The floating anti-collision module 3 uses a flexible or floating structure design to buffer the impact energy of ships or floating objects, avoiding direct damage to the retaining wall. It is suitable for navigable waterways or areas with frequent human activity.

[0032] Dynamic adjustment of permeable buffer layer 2: The gravel-geotextile composite layer between the ecological retaining wall and the ground layer 1 has both permeability and filtration functions, allowing water to slowly infiltrate, regulating the groundwater level, preventing soil loss, dispersing structural stress, and enhancing overall durability.
