Description

Technical Field

[0001] This application relates to the field of wastewater treatment plant construction technology, and in particular to a green space drainage outlet structure for urban wastewater treatment plant construction. Background Technology

[0002] With the acceleration of urbanization, the demand for the construction and renovation of urban sewage treatment plants is increasing. As an important component of sewage treatment plants, the design rationality of green space drainage outlets directly affects drainage efficiency and sewage treatment effect.

[0003] For areas with potentially weak foundations in wastewater treatment plants, conventional lime-soil cushion layers are insufficient to meet the bearing capacity requirements of the supports, easily leading to support settlement and tilting, which in turn causes uneven stress on pipe joints and leakage. Regarding pipes and ancillary structures, the debris-proof devices installed at rainwater inlets are mostly fixed structures, making cleaning inconvenient and prone to long-term debris accumulation and blockage of the inlets. Furthermore, the amount of debris carried by rainwater varies significantly across seasons, and existing fixed protective structures cannot flexibly adapt, easily resulting in poor interception or increased drainage resistance. Utility Model Content

[0004] To address the problems of settlement and tilting in existing sewage treatment plant construction green space drainage pipes, which lead to uneven stress and leakage, this application provides a structure for the drainage outlet of a green space in an urban sewage treatment plant construction.

[0005] This application provides a structure for a green space drainage outlet in the construction of an urban wastewater treatment plant, employing the following technical solution: A drainage outlet structure for a green space in a municipal wastewater treatment plant includes a structural wall, a recessed green space, and drainage components. The structural wall is located on one side of the recessed green space, and the drainage components are installed on the central axis of the recessed green space, with multiple sets of drainage components arranged along the central axis. The recessed green space has a recessed filling section, within which a first stabilizing component laid on undisturbed soil and a second stabilizing component filling the first stabilizing component are provided. One end of each drainage component extends into the second stabilizing component, and the other end extends out of the second stabilizing component. The end extending into the second stabilizing component is connected to a water-flowing component, which is installed on the structural wall. A reinforcing section is also provided around the end of each drainage component extending out of the second stabilizing component, and the reinforcing section is embedded in the second stabilizing component.

[0006] By adopting the above technical solution, setting up multiple sets of drainage components can improve drainage efficiency; the first stabilizing component can evenly transfer the load on the second stabilizing component to the original soil, reducing the settlement and uneven deformation of the entire green space; the reinforcing part can better support the drainage components, avoid their deformation, cracking and positional displacement, and ensure the stable operation of the drainage components.

[0007] Preferably, the second stabilizing component includes an implant portion and a filler portion, wherein the filler portion fills the first stabilizing component and the implant portion is laid on the filler portion.

[0008] By adopting the above technical solution, the filler part is filled on the first stabilizing component, and the planting part is laid on the filler part. The gravel and coarse sand in the filler part can ensure drainage through large pores and enhance overall stability. The planting part can provide nutrients, aeration space and a stable growth environment for vegetation, thereby improving the sand-fixing and soil-stabilizing effect and reducing the amount of sand and soil flowing into the drainage component.

[0009] Preferably, vegetation is planted on the planting section.

[0010] By adopting the above technical solutions, planting vegetation on the planting section can improve the effect of sand prevention and soil stabilization, and reduce the amount of sand and soil flowing into the drainage components.

[0011] Preferably, each set of drainage components includes a drainage component and a filter component for filtering debris. One end of the drainage component is inserted into the second stabilizing component and extends along the surface of the first stabilizing component before being connected to the water flow component. The other end is exposed outside the second stabilizing component. The filter component is rotatably connected to the exposed end of the second stabilizing component and is detachably connected.

[0012] By adopting the above technical solution, the drainage component can be connected with the water flow component to realize the drainage function. The filter component can filter debris and is rotatable and detachable connected to the drainage component, which facilitates cleaning of garbage in the pipe. Together with the structural wall, sunken green space, first stabilizing component, second stabilizing component, and reinforcement component, the drainage function is realized, reducing green space settlement and uneven deformation, and ensuring the stable operation of the drainage component.

[0013] Preferably, the drainage component has a soil-stabilizing part around its center, and the soil-stabilizing part is embedded in the second stabilizing component.

[0014] By adopting the above technical solution, the drainage component includes a drainage component and a filter component. One end of the drainage component is inserted into the second stabilizing component and connected to the water flow component, while the other end is exposed. The filter component is rotatable and detachably connected to the exposed end of the drainage component. The soil stabilizing part is embedded in the second stabilizing component. The geotextile filter membrane wrapped around the soil stabilizing part can filter mud and water, allowing clean water to enter the plastic blind ditch and be discharged, thereby reducing the settlement of the green space.

[0015] Preferably, the drainage component has a bend that contacts the surface of the first stabilizing component; a supporting component is provided at the bend, the supporting component wraps around the bend and is mounted on the first stabilizing component.

[0016] By adopting the above technical solution, the bend of the drainage component contacts the surface of the first stabilizing component, and a supporting component is provided at the bend to wrap around the bend and install it on the first stabilizing component, which can protect the drainage pipe and enhance the stability of the drainage component on the second stabilizing component.

[0017] Preferably, the space between the supporting component and the first stabilizing component is filled with the base portion of the stabilizing supporting component.

[0018] By adopting the above technical solution, the structural wall, sunken green space, and multiple sets of drainage components are set up, enabling the drainage components to be rationally arranged for drainage. The filling part of the sunken green space is equipped with a first stabilizing component and a second stabilizing component, which can evenly transfer the load and reduce green space settlement and uneven deformation. The drainage components are reinforced around their extended ends to support them and prevent deformation, cracking, and displacement. The second stabilizing component is equipped with a planting section and a filling section to meet different functional requirements. The planting section is planted with vegetation to prevent sand and soil stabilization and reduce the inflow of sand and soil into the drainage components. The drainage components are equipped with drainage components and filter components, and the filter components are detachable for easy garbage removal. The drainage components are equipped with a soil stabilizing section in the middle to filter mud and water and reduce green space settlement. The drainage components are equipped with a supporting component at the bend to reinforce them and improve stability. The filling base between the supporting component and the first stabilizing component provides a stable foundation for the supporting component and improves the overall support stability.

[0019] Preferably, the foundation includes a soil cushion layer and a lime layer, wherein the lime layer and the soil cushion layer are mixed in a 3:7 ratio to form a lime-soil cushion layer.

[0020] By adopting the above technical solution, a soil cushion layer composed of a 3:7 mixture of soil and lime is set between the support component and the first stabilizing component at the bend of the drainage component. This provides a stable foundation for the construction of the pipe support, improves the overall support stability, strengthens the drainage component, enhances the stability of the green space drainage pipe on the second stabilizing component, and protects the green space drainage pipe.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a green space drainage outlet structure for the construction of an urban sewage treatment plant. (See also...) Figure 1 and Figure 2 The system includes a structural wall 2, a sunken green space 3, and drainage components 4. The structural wall 2 is located on one side of the sunken green space 3. The drainage components 4 are installed on the central axis of the sunken green space 3, and multiple sets of drainage components 4 are arranged along the central axis. The sunken green space 3 has a sunken filling part 31. The filling part 31 contains a first stabilizing component 32 laid on the original soil 1 and a second stabilizing component 33 filled on the first stabilizing component 32. One end of each drainage component 4 extends into the second stabilizing component 33, and the other end extends out of the second stabilizing component 33. The end extending into the second stabilizing component 33 is connected to a water-flowing component (not shown in the figure), which is installed on the structural wall 2. A reinforcing part 5 is also provided around the end of each drainage component 4 that extends out of the second stabilizing component 33, and the reinforcing part 5 is embedded in the second stabilizing component 33.

[0026] Specifically, see Figure 1 and Figure 2 The filling part 31 includes a green space trench opened on the original soil 1. The first stabilizing component 32 includes a geotextile laid on the bottom of the green space trench, which is used to evenly transfer the load on the second stabilizing component 33 to the original soil 1, thereby reducing the settlement and uneven deformation of the entire green space.

[0027] The second stabilizing component 33 includes an implantation part 330 and a filler part 331. The filler part 331 fills the first stabilizing component 32, and the implantation part 330 is laid on the filler part 331.

[0028] The reinforcing part 5 includes pebbles, which fill each set of drainage components 4 to better support the drainage components 4 and prevent the drainage components 4 from being unable to withstand the pressure of the second stabilizing part 33 and the accumulated water, thus preventing deformation, cracking and displacement, and ensuring stable operation of the drainage components 4.

[0029] The planting section 330 is planted with vegetation, which can improve the effect of sand control and soil stabilization, and reduce the amount of sand and soil flowing into the drainage component 4. The planting section 330 includes local high-quality garden soil, decomposed organic matter, and lightweight aggregate. The three materials are mixed to form planting soil, thereby providing nutrients, aeration space, and a stable growing environment for the vegetation.

[0030] The filler layer consists of crushed stone and coarse sand. The crushed stone and coarse sand are mixed to form the filler layer material. The crushed stone can ensure drainage through large pores, while the coarse sand fills the gaps between the crushed stone, preventing the leakage of fine particles from the upper layer of filler, and at the same time enhancing the overall stability.

[0031] Further, see Figure 1 and Figure 2 Each drainage assembly 4 includes a drainage component 41 and a filter component 42 for filtering debris. One end of the drainage component 41 passes through the second stabilizing component 33 and extends along the surface of the first stabilizing component 32 before connecting to the water flow assembly. The other end protrudes from the second stabilizing component 33. The filter component 42 is rotatably connected to the exposed end of the second stabilizing component 33 and is detachably connected. A soil-stabilizing part 6 is provided around the middle of the drainage component 41, and the soil-stabilizing part 6 is embedded in the second stabilizing component 33.

[0032] Specifically, see Figure 1 and Figure 2 The drainage component 41 includes a green space drainage pipe. One end of the green space drainage pipe is inserted into the second stabilizing component and extends along the surface of the first stabilizing component 32 to the structural wall 2, and then connects to the water flow component on the structural wall 2. The other end is exposed outside the second stabilizing component 33.

[0033] The filter component 42 includes a plastic planting filter screen, which is threadedly connected to the green space drainage pipe and can be detached from the green space drainage pipe. By rotating the plastic planting filter screen, it can be locked onto or detached from the green space drainage pipe, which is beneficial for subsequent cleaning of garbage in the pipe.

[0034] The drainage assembly includes a drainage pipe in structural wall 2, which is fixedly installed on structural wall 2. One end of the green space drainage pipe, which is buried in the second stabilization, is connected to the drainage pipe in structural wall 2.

[0035] The soil stabilization section 6 includes plastic drainage material, which consists of a plastic core and an outer geotextile filter membrane. The plastic core is typically made from polypropylene, polyethylene, or their copolymers. After modification, it is extruded into fine plastic filaments through a nozzle in a hot-melt state. These filaments are then disordered and fused together at the nodes using a molding device, forming a three-dimensional mesh structure, similar to a loofah sponge. This structure gives the core a high porosity, low water flow resistance, and good drainage. The outer geotextile filter membrane surrounding the core filters muddy water, allowing clean water to enter the plastic drainage ditch and drain away, reducing the occurrence of green space subsidence.

[0036] Further, see Figure 1 The drainage component 41 has a bend (not shown in the figure) that contacts the surface of the first stabilizing component 32. A support component (not shown in the figure) is provided at the bend, which wraps around the bend and is mounted on the first stabilizing component 32. The base portion of the stabilizing support component (not shown in the figure) is filled between the support component and the first stabilizing component 32.

[0037] Specifically, the bends include elbows, tees, and plugs of the green space drainage pipes. By constructing supporting components at these locations, the green space drainage pipes can be protected and their stability enhanced. The supporting components include pipe supports, which are fixedly installed on the first stabilizing component 32. The pipe supports are used to reinforce each drainage assembly 4 and improve the stability of the green space drainage pipes on the second stabilizing component 33.

[0038] The foundation consists of a soil cushion layer and a lime layer, which are mixed in a 3:7 ratio to form a lime-soil cushion layer. The soil cushion layer and lime layer are mixed in a specific ratio to form the lime-soil cushion layer, and during installation, it is compacted in layers to achieve a certain thickness, providing a stable foundation for the construction of pipeline supports and improving the overall support stability.

[0039] The working principle of the green space drainage outlet structure in the construction of an urban sewage treatment plant according to this application is as follows: This technology achieves drainage by combining layered stabilization with directional drainage. First, the filling part 31 of the sunken green space 3 is based on the original soil 1, and geotextile is laid at the bottom as the first stabilizing component 32 to evenly transfer the upper load to the original soil 1; the second stabilizing component 33 above it is divided into two layers. The lower filling part 331 (a mixture of crushed stone and coarse sand) uses the large pores of crushed stone to ensure drainage space and coarse sand to prevent fine particles from leaking in. The upper planting part 330 (a mixture of garden soil, decomposed organic matter, and lightweight aggregate) provides vegetation growth, and the vegetation at the same time reduces the amount of sand and gravel entering the soil. Drainage components 4 are laid out along the central axis of the green space. One end of the drainage pipe of each drainage component 4 is inserted into the second stabilizing component 33, extends along the first stabilizing component 32 to the structural wall 2 and connects to the drainage pipe (water flow component) of the structural wall 2. The other end is exposed and connected to the plastic planting filter (filter component 42) through a thread to intercept debris. The plastic blind drain material (soil stabilizing part 6) in the middle of the drainage pipe filters mud and water and assists in drainage. The bends such as elbows / tees are wrapped by pipe supports (supporting parts). The support is stabilized by a 3:7 lime-soil cushion layer (foundation part) that is compacted in layers. Rainwater infiltrates through the planting part 330 and is guided by the filling part 331. After being filtered by the filter, it enters the drainage pipe and is discharged through the drainage pipe of the structural wall 2. At the same time, pebbles (reinforcing part 5) surround the exposed end to enhance the stability of the drainage component 4.

[0040] This technical solution achieves multiple functions of green space drainage, vegetation cultivation, and structural stability. It can efficiently drain accumulated water from green spaces, provide a suitable growth environment for vegetation, and ensure the long-term stability of the drainage system. The layered design of the stabilizing components (geotextile, lime-soil cushion layer, and pipe supports) effectively reduces green space settlement and uneven deformation, preventing the drainage component 4 from deforming and breaking due to load or water pressure. The sand and gravel ratio of the filler section 331, combined with the water-filtering structure of the plastic blind drain material, balances drainage efficiency and anti-clogging effect. The detachable plastic planting filter facilitates subsequent cleaning and reduces the difficulty of pipe maintenance. The dual interception of vegetation and filter reduces impurities entering the drainage system, further reducing the risk of clogging. The core problems solved include the easy displacement of drainage component 4 due to settlement of traditional green space drainage outlets, pipe rupture due to water pressure, and the easy clogging of drainage systems by sand and gravel, making maintenance inconvenient. It also solves the problem of poor synergy between green space soil and drainage structure, making it difficult to balance drainage and vegetation growth.
