Description

Technical Field

[0001] This utility model relates to the field of rain garden technology, and in particular to a prefabricated modular campus green space rain garden module based on sponge city. Background Technology

[0002] As an important part of the city, campuses, characterized by their large area and abundant green space, are crucial sites for the implementation of sponge city construction. Campus green space rain gardens, as a key facility in sponge city construction, play a vital role in collecting, purifying, and utilizing rainwater. They not only effectively reduce urban surface runoff and lower the risk of flooding, but also, on sunny days, pump out the water collected in the rainwater harvesting modules to provide moisture for the plants in the garden, thus improving the campus ecological environment.

[0003] However, during continuous rainfall, the rainwater harvesting modules in existing campus green space rain gardens can cause severe water accumulation in the upper flower beds when their internal water storage capacity reaches saturation. This oversaturation directly leads to secondary damage such as root hypoxia and rot, seriously affecting the ecological efficiency and usability of the rainwater harvesting modules. In addition, the lack of reliable connection and reinforcement structures between existing rainwater harvesting modules makes them prone to displacement under long-term water and soil pressure, reducing their structural stability. Utility Model Content

[0004] This utility model relates to a prefabricated modular campus green space rain garden module based on sponge city, which solves the problem that the existing rainwater collection modules in campus green space rain gardens become saturated with water during continuous rainfall, resulting in severe water accumulation in the upper flower beds, causing damage to plants, thereby reducing ecological efficiency and use value. In addition, the lack of connecting and reinforcing structures between rainwater collection modules makes them prone to displacement under long-term loads, thus reducing stability.

[0005] The first aspect of this utility model provides a prefabricated modular campus green space rain garden module based on sponge city principles, specifically comprising: a campus green space, wherein a foundation pit is opened in the campus green space, and a composite geomembrane is installed in the foundation pit; a rainwater collection device is wrapped inside the composite geomembrane, and a pumping pipe support is provided in the middle of the rainwater collection device; flower bed side stones are laid on the top of the campus green space outside the composite geomembrane, and overflow holes are opened on the flower bed side stones, with the overflow holes located above the rainwater collection device; a permeable geotextile is laid on the top of the rainwater collection device outside the pumping pipe support, and planting soil is provided on the upper surface of the permeable geotextile for planting green plants.

[0006] Furthermore, the rainwater harvesting device includes a rainwater harvesting module, which is installed inside the composite geomembrane. The rainwater harvesting module has a first side plate installed on its left and front sides, and a second side plate installed on its right and rear sides.

[0007] Furthermore, the rainwater harvesting module includes a connecting plate, on which four conical support cylinders are fixedly connected, and the four conical support cylinders and the connecting plate are an integrated structure. The left and front sides of the connecting plate are provided with T-shaped assembly openings, and the right and rear sides of the connecting plate are provided with T-shaped assembly blocks. The upper surface of the connecting plate is provided with a water inlet. The T-shaped assembly openings on the connecting plate can be spliced ​​with the T-shaped assembly blocks provided on another connecting plate.

[0008] Furthermore, two of the conical support cylinders on the connecting plate are provided with positioning holes, and the other two conical support cylinders on the connecting plate are provided with positioning posts. The two positioning posts in the upper rainwater collection module can be inserted into the two positioning holes in the lower rainwater collection module.

[0009] Furthermore, the first side plate is provided with a T-shaped slide bar, and the T-shaped slide bar can be slidably connected with the T-shaped assembly port; the second side plate is provided with a T-shaped slide groove, and the T-shaped slide groove can be slidably connected with the T-shaped assembly block.

[0010] Furthermore, the pumping pipe support includes a support frame, which is located in the middle of the rainwater collection device. A top plate and a bottom plate are fixedly connected to the upper and lower ends of the support frame, respectively. The bottom plate is in contact with the inner bottom surface of the composite geomembrane and is used to install a submersible pump. Four baffles are fixedly connected to the bottom surface of the top plate, and a pumping pipe through hole is opened in the middle of the upper surface of the top plate for the pumping pipe to pass through.

[0011] This utility model provides a prefabricated modular campus green space rain garden module based on sponge city principles, which has the following beneficial effects: 1. This utility model provides an overflow hole on the side stone of the flower bed, located above the rainwater collection device. When the water inside the rainwater collection module reaches the designed capacity, excess rainwater will automatically overflow through the overflow hole, forming a reliable overflow protection mechanism. This prevents excessive water accumulation in the upper flower bed, avoids secondary damage such as oxygen deficiency and rot of plant roots, and effectively improves the ecological efficiency and use value of the rainwater collection module.

[0012] 2. This utility model features an interlocking connection structure with T-shaped assembly openings and T-shaped assembly blocks on the connecting plates. By splicing the T-shaped assembly openings on one connecting plate with the T-shaped assembly blocks on another connecting plate, this interlocking connection method provides a reliable connection and reinforcement between rainwater harvesting modules. This makes the rainwater harvesting modules less prone to displacement during long-term use, thereby improving the structural stability of the rainwater harvesting modules.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1 to 8 : This utility model proposes a prefabricated modular campus green space rain garden module based on sponge city principles, comprising: a campus green space 1, with a foundation pit in the campus green space 1, and a composite geomembrane 3 installed within the foundation pit; a rainwater collection device 4 is wrapped inside the composite geomembrane 3, and a pumping pipe support 5 is installed in the middle of the rainwater collection device 4; flower bed curb stones 2 are laid on the top of the campus green space 1 outside the composite geomembrane 3, and overflow holes 201 are opened on the flower bed curb stones 2, and the overflow holes 201 are located at... Above the rainwater harvesting device 4, when the water inside the rainwater harvesting module 401 reaches the design capacity, excess rainwater will automatically overflow through the overflow hole 201, forming a reliable overflow protection mechanism. This effectively prevents the upper flower bed from accumulating too much water, avoiding secondary hazards such as oxygen deficiency and rot of plant roots, and improving the ecological efficiency and use value of the rainwater harvesting module 401. The top of the rainwater harvesting device 4 is covered with a permeable geotextile 6 outside the pumping pipe support 5. Planting soil is set on the upper surface of the permeable geotextile 6 for planting green plants.

[0018] The rainwater harvesting device 4 includes a rainwater harvesting module 401, which is installed inside the composite geomembrane 3. A first side plate 402 is installed on the left and front sides of the rainwater harvesting module 401, and a second side plate 403 is installed on the right and rear sides of the rainwater harvesting module 401 to reinforce the edges of the rainwater harvesting module 401.

[0019] The pumping pipe support 5 includes a support frame 501, which is located in the middle of the rainwater collection device 4. The upper and lower ends of the support frame 501 are respectively fixedly connected to a top plate 502 and a bottom plate 503. The bottom plate 503 is in contact with the inner bottom surface of the composite geomembrane 3 and is used to install a submersible pump. Four baffles 504 are fixedly connected around the bottom surface of the top plate 502, and a pumping pipe through hole 505 is opened in the middle of the upper surface of the top plate 502 for the pumping pipe to pass through. The pumping pipe support 5 facilitates the installation of pumping equipment, which transports rainwater from the rainwater collection module 401 to the flower bed or the campus green space 1, so that the plants in the flower bed and the campus green space 1 can be replenished with water in a timely manner on sunny days.

[0020] Example 2, based on Example 1, such as Figures 2 to 7 As shown, the rainwater harvesting module 401 includes a connecting plate 4011, on which four conical support cylinders 4012 are fixedly connected. The four conical support cylinders 4012 and the connecting plate 4011 are an integrated structure. T-shaped assembly openings 4013 are provided on the left and front sides of the connecting plate 4011, and T-shaped assembly blocks 4014 are provided on the right and rear sides of the connecting plate 4011. A water inlet 4015 is provided on the upper end face of the connecting plate 4011. The T-shaped assembly openings 4013 on the connecting plate 4011 can be spliced ​​with the T-shaped assembly blocks 4014 provided on another connecting plate 4011. This interlocking connection method provides a reliable connection and reinforcement between the rainwater harvesting modules 401, making it less prone to displacement during long-term use and improving the structural stability of the rainwater harvesting module 401.

[0021] The connecting plate 4011 has two conical support cylinders 4012 with positioning holes 4016, and the connecting plate 4011 has two other conical support cylinders 4012 with positioning posts 4017. The two positioning posts 4017 in the upper rainwater collection module 401 can be inserted into the two positioning holes 4016 in the lower rainwater collection module 401, so that the upper and lower rainwater collection modules 401 are effectively positioned.

[0022] The first side plate 402 is provided with a T-shaped slide bar 4021, and the T-shaped slide bar 4021 can be slidably connected with the T-shaped assembly port 4013; the second side plate 403 is provided with a T-shaped slide groove 4031, and the T-shaped slide groove 4031 can be slidably connected with the T-shaped assembly block 4014.

[0023] The working principle of this embodiment is as follows: During assembly, a foundation pit is first opened on the campus green space 1, and then a composite geomembrane 3 is installed in the foundation pit. Next, the rainwater collection module 401 is assembled inside the composite geomembrane 3. When assembling the rainwater collection module 401, the rainwater collection modules 401 in the horizontal direction can be spliced ​​by connecting the T-shaped assembly port 4013 opened on the connecting plate 4011 with the T-shaped assembly block 4014 set on another connecting plate 4011. The rainwater collection modules 401 in the vertical direction can be connected by inserting the two positioning pins 4017 in the upper rainwater collection module 401 with the two positioning holes 4016 in the lower rainwater collection module 401, so that the rainwater collection modules 401 can be reliably connected and reinforced.

[0024] After assembling the upper and lower rainwater collection modules 401 together, the first side plate 402 is slidably connected to the T-shaped assembly port 4013 via the T-shaped slide bar 4021, and the second side plate 403 is slidably connected to the T-shaped assembly block 4014 via the T-shaped slide groove 4031, thereby assembling the first side plate 402 and the second side plate 403 onto the outside of the rainwater collection module 401. Then, following the same operation, the rainwater collection module 401 is assembled above the lower rainwater collection module 401. After all the rainwater collection modules 401 are assembled, the pumping pipe bracket 5 is installed in the middle of the rainwater collection device 4. Then, a permeable geotextile 6 is laid on the top of the rainwater collection device 4 outside the pumping pipe bracket 5, and planting soil is set on the upper surface of the permeable geotextile 6. Finally, green plants are planted.

[0025] During rainfall, rainwater seeps through the planting soil and the permeable geotextile 6 on its upper surface and enters the rainwater collection module 401. When the water storage capacity inside the rainwater collection module 401 reaches saturation, excess rainwater will overflow through the overflow hole 201 on the flower bed side stone 2, thereby preventing serious water accumulation in the upper flower bed and avoiding secondary hazards such as oxygen deficiency and rot of plant roots.
