Description

Technical Field

[0001] The present invention relates to the technical field of gardening and greening, and in particular to an integrated greening retaining wall combined with a sponge city. Background Art

[0002] In road or highway projects, there are usually tall vertical retaining walls. Retaining walls play a positive role in stabilizing slopes and preventing river bank erosion. However, due to the long exposed parts of tall retaining walls, they are not well coordinated with the surrounding environment and do not meet ecological and environmental protection requirements and aesthetic needs. For this type of vertical retaining wall, vertical greening plants or climbing plants are often planted for greening coverage. On the one hand, climbing plants grow slowly, and on the other hand, the length of the plants themselves is not enough to cover the entire wall, resulting in serious wall exposure. In addition, in areas with large traffic, measures such as external flower boxes are also tried to achieve greening coverage, but this type of flower box requires external support or requires a large amount of water for irrigation, which will greatly increase costs for areas that lack external irrigation systems.

[0003] Therefore, there is a need for a green retaining wall that can combine rainwater drainage and integrated design. Summary of the invention

[0004] In view of this, an embodiment of the present application provides an integrated green retaining wall combined with a sponge city, which can be combined with rainwater discharge to achieve greening irrigation.

[0005] The first aspect of the embodiment of the present application provides an integrated green retaining wall combined with a sponge city, including a wall body and a support body integrally and hierarchically arranged on the wall body, a side wall flower trough for planting is detachably arranged between the support body and the wall, a water storage tank is formed between the side wall flower trough and the support body, a grass planting ditch is arranged on the top of the wall body, a rainwater irrigation pipe for collecting rainwater is buried in the grass planting ditch, the rainwater irrigation pipe extends downward along the wall surface and is connected to the water storage tank.

[0006] The embodiment of the present application forms a support body through integrated casting, which can reduce construction costs and form multi-layered flower beds, which have integrity from the facade. The detachable design of the side wall flower beds not only provides flexibility and modularity, but also facilitates later maintenance and replacement. The top grass-planting ditch and rainwater irrigation pipe increase the rainwater collection capacity, provide a stable irrigation water source, reduce dependence on artificial irrigation, and ensure the effective use of water resources.

[0007] In one embodiment, a cantilever body is provided at a position corresponding to the top of the wall body and the support body, and a top flower trough for planting is formed between the cantilever body and the wall body, and the top flower trough has a top opening.

[0008] The embodiment of the present application increases the space utilization of the top flower trough through the design of the cantilever body, avoiding the structural instability problem that may be caused by the traditional external flower box. The top flower trough with an open top simplifies plant planting and daily maintenance work, and improves the convenience and efficiency of greening. This design optimizes the use of space, improves the safety and aesthetics of the overall structure, and makes the integrated green retaining wall combined with the sponge city more visually coherent and harmonious.

[0009] In one embodiment, the rainwater irrigation pipe penetrates the wall and extends into the top flower trough to irrigate the top flower trough. The rainwater irrigation pipe penetrates the bottom of the top flower trough and extends downward along the wall.

[0010] The embodiment of the present application realizes a comprehensive irrigation system from top to bottom by designing that the rainwater irrigation pipe runs through the wall and extends into the top flower trough. This method not only ensures sufficient irrigation of the top flower trough, but also because the irrigation pipe runs through the bottom of the top flower trough and extends down along the wall, it can effectively distribute water to the water storage tanks at all levels, promoting uniform water supply of the entire vertical greening system. This design improves irrigation efficiency and reduces the problem of uneven water supply caused by different positions.

[0011] In one embodiment, the support body is tilted on the wall, a V-shaped angle is formed between the upper surface of the support body and the wall, the side wall flower groove is embedded in the V-shaped angle, and a V-shaped planting area with a top opening is formed between the upper surface of the side wall flower groove and the wall, and the V-shaped planting area is used to fill the planting matrix.

[0012] The embodiment of the present application uses a design in which the support body is tilted and forms a V-shaped angle with the wall, so that the side wall flower trough is embedded therein, forming a unique V-shaped planting interval. This helps to enhance the overall stability and shear resistance of the retaining wall, and also provides a natural growth environment for the plant roots, which is conducive to the healthy growth of plants. The open design of the V-shaped planting interval facilitates the filling of the planting matrix, simplifies the construction process, and reduces the difficulty and time of construction.

[0013] In one embodiment, a water absorption strip is provided between the upper surface of the side wall flower groove and the planting matrix, and the water absorption strip is used to absorb the liquid in the water storage tank into the planting matrix.

[0014] The embodiment of the present application realizes water transfer between the water storage tank and the planting matrix through the water absorption strip, which can effectively and evenly absorb the water in the water storage tank into the planting matrix, ensuring that the roots of the plants are continuously and appropriately supplied with water. This not only improves the utilization rate of water resources, but also reduces plant growth problems caused by excessive or insufficient irrigation, ensures the healthy growth of plants, and also reduces maintenance costs.

[0015] In one embodiment, the support body and the wall body are connected by connecting embedded reinforcement and are cast as one body.

[0016] The embodiment of the present application significantly enhances the connection strength and durability between the support and the wall by combining the connection of the embedded reinforcement and the integrated casting process. It eliminates the safety hazards of the traditional external hanging method, prolongs the service life of the structure, and also provides a solid foundation for subsequent greening projects. The integrated casting also improves the construction speed and quality control level, reduces the uncertainties in the construction process, and ensures the quality of the project.

[0017] In one embodiment, the grass-planting ditch has a top opening, and the inside of the grass-planting ditch is used to fill a planting matrix. The surface of the planting matrix of the grass-planting ditch is provided with a rainwater filter body for covering the inlet of the rainwater irrigation pipe to filter rainwater.

[0018] The embodiment of the present application effectively intercepts and filters impurities entering the rainwater irrigation pipe by setting up a rainwater filter in the grass-planting ditch, prevents pipe blockage, and ensures the long-term stable operation of the irrigation system. The existence of the filter not only protects the irrigation system, but also improves the environmental performance of the entire integrated green retaining wall combined with the sponge city, reducing maintenance frequency and cost. In addition, the filter can also improve water quality and provide a healthier growth environment for plants.

[0019] In one embodiment, the rainwater irrigation pipe includes a rainwater main pipe and a rainwater branch pipe. One end of the rainwater main pipe is buried in the grass planting ditch, and the other end extends downward along the wall surface. The rainwater branch pipe is provided at the corresponding position of the side wall flower groove on each floor, and is used to connect to the water storage tank.

[0020] The embodiment of the present application ensures that each layer of water storage tanks can be evenly and stably supplied with water by adopting a hierarchical irrigation network composed of rainwater main pipes and branch pipes, which is conducive to maintaining the normal growth of plants.

[0021] In one embodiment, the top flower trough is used to sequentially arrange a water storage layer, an isolation layer and a planting matrix from bottom to top, and the isolation layer is made of a permeable material.

[0022] The embodiment of the present application sets a layered structure of a water storage layer, an isolation layer and a planting matrix inside the top flower trough, providing good growth conditions for plants. The isolation layer made of permeable material can not only maintain soil moisture, but also prevent excessive water loss, maintain a suitable soil environment, and prevent soil from falling into the water storage layer to affect water storage. This structure optimizes the respiration of plant roots, ensures the water storage capacity of the water storage layer, and also helps to maintain the stability of the soil structure and reduce the risk of soil erosion.

[0023] In one embodiment, the cantilever body is provided with a first overflow pipe at a specified height and connected to the water storage layer of the top flower trough, and the support body is provided with a second overflow pipe at a specified height and connected to the water storage tank.

[0024] The designs of the first overflow pipe and the second overflow pipe in the embodiment of the present application correspond to the water storage layer of the top flowerbed and the water storage tank of the support body, respectively, ensuring that excess water can be quickly discharged when the rainfall is too heavy, preventing suffocation of plant roots and other damage caused by accumulated water, and can achieve layer-by-layer irrigation through the overflow pipe, effectively utilizing water sources and avoiding waste of water resources.

[0025] The integrated green retaining wall combined with the sponge city provided in the embodiment of the present application can reduce the construction cost by forming a support body through integrated casting, and can form a multi-layer flower trough, which has integrity from the facade. The detachable design of the side wall flower trough not only provides flexibility and modularity, but also facilitates later maintenance and replacement. The top grass-planting ditch and rainwater irrigation pipe increase the rainwater collection capacity, provide a stable irrigation water source, reduce dependence on artificial irrigation, and ensure the effective use of water resources.

The rainwater irrigation pipe 2 extends downward along the wall surface and is connected to the water storage tank 5 .

[0039] In application, sponge city is a modern urban stormwater management concept, which aims to make the city like a sponge through a series of measures, so that it has good "elasticity" in adapting to environmental changes and responding to natural disasters. The construction goal of sponge city is to effectively collect, purify and store rainwater through a combination of natural and artificial methods, reduce the risk of urban waterlogging, replenish groundwater resources and improve the urban ecological environment.

[0040] In application, the wall 7 is cast with concrete and has sufficient strength and stability to support the greening facilities above. The support 3 is also made of concrete material and is cast integrally with the wall 7 during construction to form a solid whole. Removable side wall flower troughs 4 are provided between the support 3 and the wall 7. These side wall flower troughs 4 are fixed to the support 3 by specially designed connectors to ensure that they are firmly installed and easy to maintain or replace later.

[0041] In use, a water storage tank 5 is formed between the side wall flower trough 4 and the support body 3, and the water storage tank 5 is used to store the collected rainwater to provide a continuous water supply for the plants. A grass planting ditch 1 is provided on the top of the wall 7, and the grass planting ditch 1 is filled with a matrix suitable for plant growth, and a rainwater irrigation pipe 2 for collecting rainwater is buried. The rainwater irrigation pipe 2 starts from the grass planting ditch 1, extends downward along the wall 7, and finally communicates with the water storage tank 5 of each layer, realizing the effective use of natural precipitation.

[0042] In one embodiment, the support body 3 and the wall body 7 are connected by connecting anchor bars 31 and are cast as one body.

[0043] In application, the support body 3 and the wall body 7 are connected by connecting and embedding bars 31 and cast as one. The connecting and embedding bars 31 are steel bars pre-arranged in the template, and solidify together with the wall body 7 and the support body 3 during the concrete pouring process to form a solid integral structure.

[0044] In the application, the number, diameter and spacing of the connecting anchor bars 31 are determined according to the structural stress analysis, ensuring that the two will not be relatively displaced during long-term use, thereby improving the safety and stability of the entire structure. Integrated casting not only improves the construction speed and quality control level, but also reduces uncertainties in the construction process and ensures the quality of the project.

[0045] In one embodiment, a cantilever body 61 is provided at a position corresponding to the top of the wall body 7 and the support body 3 , and a top flower trough 6 for planting is formed between the cantilever body 61 and the wall body 7 , and the top flower trough 6 has a top opening.

[0046] In application, a cantilever body 61 is provided at the top of the wall body 7 at a position corresponding to the support body 3, and the cantilever body 61 can be connected with the wall body 7 by planting reinforcement and / or integral casting to form a whole. The cantilever body 61 is designed with a reinforced concrete structure to ensure a firm connection between it and the wall body 7. The top flower trough 6 formed between the cantilever body 61 and the wall body 7 has a top opening, which is convenient for plant planting and daily maintenance.

[0047] In use, the top flower trough 6 is sequentially arranged with a water storage layer 64, an isolation layer 63 and a planting matrix 62 from bottom to top. The water storage layer 64 is composed of loose gravel, which helps to improve drainage performance; the isolation layer 63 prevents the upper planting soil from entering the water storage layer; and the planting matrix is ​​used to plant vertical greening plants. A first overflow pipe is reserved at the top of the water storage layer 64. When the water level reaches a certain height, excess rainwater will be discharged in time and enter the next layer of flower troughs.

[0048] In one embodiment, Figure 4 As shown, the support body 3 is tiltedly arranged on the wall 7, a V-shaped angle is formed between the upper surface of the support body 3 and the wall 7, the side wall flower groove 4 is embedded in the V-shaped angle, and a V-shaped planting area with an open top is formed between the upper surface of the side wall flower groove 4 and the wall 7, and the V-shaped planting area is used to fill the planting matrix 41, 62.

[0049] In application, the support body 3 is tiltedly arranged on the wall body 7, and a V-shaped angle is formed between the upper surface of the support body 3 and the wall body 7. The tilt angle of the support body 3 is precisely calculated, which not only ensures the stability of the structure, but also provides a good embedding space for the side wall flower trough 4. The side wall flower trough 4 is embedded in this V-shaped angle, and a V-shaped planting area with an open top is formed between the upper surface of the side wall flower trough 4 and the wall body 7.

[0050] In application, the V-shaped planting interval is used to fill the planting matrix 41, 62, which provides the necessary nutrients and growth environment for the plants. The open design of the V-shaped planting interval is not only convenient for filling the planting matrix, but also simplifies the construction process, reduces the construction difficulty and time. In addition, the V-shaped angle design enhances the overall stability of the retaining wall, provides a natural growth space for the plant roots, and is conducive to the healthy growth of plants.

[0051] In one embodiment, Figure 5 and 6 As shown, the rainwater irrigation pipe 2 passes through the wall 7 and extends into the top flower trough 6 to irrigate the top flower trough 6. The rainwater irrigation pipe 2 passes through the bottom of the top flower trough 6 and extends downward along the wall.

[0052] In application, the rainwater irrigation pipe 2 penetrates the wall 7 and extends into the top flower trough 6 to irrigate the top flower trough 6. Specifically, the rainwater irrigation pipe 2 passes through the wall 7 from the bottom of the grass-planting ditch 1 and extends obliquely downward into the top flower trough 6.

[0053] In use, the rainwater irrigation pipe 2 runs through the bottom of the top flower trough 6 and extends downward along the wall 7. This design ensures that the rainwater collected from the grass-planting ditch 1 can smoothly reach the top flower trough 6 to achieve comprehensive irrigation. At the same time, the layout of the irrigation pipe 2 takes into account the uniform distribution of water flow, avoiding the problem of excessive or insufficient local water. The inlet of the rainwater irrigation pipe 2 is located in the grass-planting ditch 1. After filtration, the rainwater is collected into the branch pipes 23 at various levels through the main pipe 22, and finally introduced into each water storage tank 5, ensuring that the water supply in the entire system is sufficient and balanced.

[0054] In one embodiment, a water absorption strip 43 is provided between the upper surface of the side wall flower groove 4 and the planting matrix 41 , 62 , and the water absorption strip 43 is used to absorb the liquid in the water storage tank 5 into the planting matrix 41 , 62 .

[0055] In application, the side wall flower trough 4 is made of a water-permeable material, and a water absorption strip 43 is provided between the upper surface of the side wall flower trough 4 and the planting matrix 41, 62. The water absorption strip 43 evenly transfers the liquid in the water storage tank 5 to the planting matrix 41, 62. The water absorption strip 43 is usually made of a material with good water absorption and conductivity, such as cellulose or synthetic fiber. One end of the water absorption strip 43 is fixed to the bottom of the side wall flower trough 4, and the other end extends into the planting matrix 41, 62. This method not only improves the utilization rate of water resources, but also reduces plant growth problems caused by excessive or insufficient irrigation. The length and density of the water absorption strip 43 are adjusted according to the specific plant species and growth requirements to ensure that the plant receives a continuous and stable water supply.

[0056] In one embodiment, the grass planting ditch 1 has a top opening and is used to fill the planting matrix 41, 62. The surface of the planting matrix 41, 62 of the grass planting ditch 1 is provided with a rainwater filter 21 for covering the inlet of the rainwater irrigation pipe 2 to filter rainwater.

[0057] In application, the grass-planting ditch 1 has a top opening, and the grass-planting ditch 1 is used to fill the planting matrix 41, 62. The structure of the grass-planting ditch 1 includes a top opening part and an inner matrix filling part. The top opening part is designed to be of appropriate width to facilitate rainwater inflow and plant planting.

[0058] In application, the surface of the planting matrix 41, 62 of the grass-planting ditch 1 is provided with a rainwater filter 21 for covering the entrance of the rainwater irrigation pipe 2. The rainwater filter 21 is usually made of non-woven fabrics and other materials that are highly permeable and not easy to rot, which not only ensures a good filtering effect, but also does not affect the smooth passage of water. After preliminary filtration, the rainwater is collected into the branch pipes 23 at various levels through the rainwater main pipe 22, and then introduced into each water storage tank 5 respectively. Each water storage tank 5 is equipped with a corresponding overflow device. When the water level reaches the set height, the excess rainwater can be discharged through the overflow pipe to avoid the accumulation of water from damaging the plant roots. At the same time, the excess rainwater can also be used to irrigate the plants on the next layer.

[0059] In one embodiment, the rainwater irrigation pipe 2 includes a rainwater main pipe 22 and a rainwater branch pipe 23. One end of the rainwater main pipe 22 is buried in the grass planting ditch 1, and the other end extends downward along the wall. The rainwater branch pipe 23 is provided at the corresponding position of each layer of the side wall flower groove 4 for connecting to the water storage tank 5.

[0060] In use, the rainwater irrigation pipe 2 includes a rainwater main pipe 22 and a rainwater branch pipe 23. One end of the rainwater main pipe 22 is buried in the grass-planting ditch 1, and the other end extends downward along the wall 7. The rainwater main pipe 22 is made of corrosion-resistant, high-strength PVC or PE material to ensure that it is not affected by the environment for long-term use.

[0061] In application, the rainwater branch pipe 23 is provided at the position corresponding to the flower slot 4 on each side wall for connecting to the water storage tank 5. This hierarchical pipe network layout not only improves the irrigation accuracy and efficiency, but also facilitates monitoring and maintenance, and reduces the complexity and failure rate of the system. The design of the rainwater main pipe 22 and the branch pipe 23 adapts to different climatic conditions, ensuring that the good growth state of the plants can be maintained even in the dry season, and enhancing the reliability and adaptability of the system.

[0062] In one embodiment, the top flower trough 6 is used to sequentially arrange a water storage layer 64, an isolation layer 63 and planting substrates 41 and 62 from bottom to top, and the isolation layer 63 is made of a water-permeable material.

[0063] In application, the top flower trough 6 is provided with a water storage layer 64, an isolation layer 63 and planting substrates 41 and 62 from bottom to top. The water storage layer 64 is composed of loose gravel, which helps to improve drainage performance; the isolation layer 63 is made of permeable material, which can not only maintain soil moisture, but also prevent excessive water loss, thus maintaining a suitable soil environment.

[0064] In application, the isolation layer 63 is usually made of non-woven fabric or other similar materials to ensure that it has good air permeability and water permeability. The water storage layer 64 is composed of crushed stones with a particle size of 20-40 mm, and the planting matrix can use a mixture of humus soil and perlite.

[0065] In application, the planting substrates 41 and 62 are used to plant vertical greening plants, which provide the plants with necessary nutrients and growth environment. This layered structure optimizes the respiration of plant roots, promotes the healthy growth of plants, and also helps to maintain the stability of soil structure and reduce the risk of soil erosion.

[0066] In one embodiment, the cantilever body 61 is provided with a first overflow pipe 65 at a specified height which is connected to the water storage layer 64 of the top flower trough 6.

The design of the first overflow pipe 65 and the second overflow pipe 24 ensures that when the rainfall is too heavy, the excess water can be quickly discharged to prevent the suffocation of plant roots and other damage caused by water accumulation. The presence of the overflow pipe also enhances the self-regulation ability of the system, adapts to different climatic conditions, and ensures the safety and stability of the entire vertical greening system. The size and position of the overflow pipe are precisely calculated to ensure that it can work normally under different water level conditions, reduce the risk of structural damage caused by water accumulation, and extend the service life of the system.
