Description

Technical Field

[0001] This utility model belongs to the field of surface runoff treatment technology and relates to a prefabricated biological retention pond. Background Technology

[0002] Sponge cities are a new urban development model that emphasizes the resilience and adaptability of cities in the face of environmental changes and natural disasters. The concept of sponge cities stems from a reflection on traditional urban construction models, which often lead to a series of ecological and environmental problems, particularly in the area of ​​water ecology. Sponge cities aim to simulate natural hydrological conditions to achieve the natural cycle and utilization of rainwater, thereby solving problems such as water scarcity, frequent flooding, and deterioration of the water ecosystem.

[0003] Bioretention ponds are currently the most widely used method, and most landscape designs use them to solve rainwater runoff problems, providing rainwater storage and filtration functions. However, the maintenance of bioretention ponds is quite complex at present. Due to limitations, there are few plant species that are both sun-tolerant and shade-tolerant, and plants need sufficient space to grow. These factors lead to poor implementation and short duration of traditional bioretention ponds. Furthermore, the filler layer in traditional bioretention ponds is generally made of composite proportion filler, which has some effect, but the infiltration effect is not obvious.

[0024] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] This embodiment proposes a prefabricated bioretention tank, including a tank body 1, an overflow well 4, a foundation trough 6, and a decorative panel 8. The tank body 1 is used to store rainwater. When the rainwater in the tank body 1 reaches a certain volume, it is discharged through the overflow well 4.

[0026] like Figures 1-2 As shown, the pool body 1 is made of metal, and the bottom of the pool body 1 is covered with a permeation layer 2, which is made of glass pumice. The metal pool body 1 can be manufactured in a modular and standardized manner, and has a long service life.

[0027] A protective layer 3 is laid on top of the infiltration layer 2. The protective layer 3 prevents rainwater from directly pouring onto the infiltration layer 2 and protects the infiltration layer 2.

[0028] The lower section of the overflow well 4 is buried in the infiltration layer 2, the upper end of the overflow well 4 protrudes from the protective layer 3, and a connecting pipe 5 is provided at the lower end of the overflow well 4. When rainwater accumulates and overflows the overflow well 4, some of the water can enter the municipal pipe network through the connecting pipe 5.

[0029] The foundation troughs 6 are fixedly installed on both sides of the pool body 1, and the bottom of the foundation troughs 6 is in contact with the protective layer 3. The foundation troughs 6 are filled with pebbles 7, which play an energy dissipation role for rainwater entering the bioretention pool. At the same time, they also have a certain effect on beautifying the bioretention pool.

[0030] The decorative panel 8 overlaps between the two base stone troughs 6. The decorative panel 8 can be decorated with patterns to replace green plants, which reduces maintenance costs and increases aesthetic value. It also has advantages in terms of safety compared to traditional biological retention ponds. A retention layer 9 is formed between the decorative panel 8 and the protective layer 3. The retention layer 9 is a water storage area to temporarily store rainwater.

[0031] Furthermore, a blind pipe 10 is provided at the lower end of the overflow well 4, and a through hole 11 that can cooperate with the blind pipe 10 is provided on one side of the pool body 1. The blind pipe 10 ensures the drainage performance of the biological retention pool.

[0032] Furthermore, the protective layer 3 is made of gravel.

[0033] Furthermore, the distance between the upper end of the overflow well 4 and the decorative panel 8 is 5-10cm. Adjusting the distance between the overflow well 4 and the support of the decorative panel 8 according to the actual situation is equivalent to adjusting the height of the retention layer.

[0034] Furthermore, the inner side plate 15 of the foundation trough 6 is provided with a number of seepage holes 12, through which rainwater can enter the pool body 1.

[0035] Furthermore, both the foundation trough 6 and the pool body 1 are made of stainless steel plates. Stainless steel has good corrosion resistance and is more durable than traditional impermeable geotextiles. Compared with traditional concrete-poured protective layers, it is more cost-effective.

[0036] Furthermore, the decorative panel 8 is made of weathering steel plate, which avoids many troubles that require maintenance and management later.

[0037] Furthermore, the foundation trough 6 is connected to the pool body 1 using corner brackets 13.

[0038] Furthermore, the inner sidewalls of the foundation stone trough 6 are respectively provided with support frames 14 that can cooperate with the decorative panels 8, and the decorative panels 8 are connected between the two foundation stone troughs 6 by means of the support frames 14.

[0039] Working principle: When using this utility model, firstly, the installation site needs to be cleaned and leveled to ensure that the ground is firm and flat and meets the installation requirements; on site, the concrete foundation bedding layer is compacted according to the standard, and blind pipes 10 are laid to ensure the stability and drainage performance of the bioretention tank.

[0040] Then, place pool 1 in the designated position according to the design requirements, and insert one end of blind tube 10 into pool 1 through through hole 11;

[0041] An overflow well 4 is installed, and connecting pipe 5 is assembled to the overflow well 4; connecting pipe 5 is then used to connect to various prefabricated biological retention tanks and the municipal pipe network to form a complete drainage system.

[0042] Next, fill the infiltration layer 2 and protective layer 3 into the pool body 1, and fill the base stone trough 6 with pebbles 7. Finally, cover it with the decorative panel. The decorative panel and the support frame can be fastened with connecting bolts.

[0043] It is understood that the above embodiments are merely exemplary models used to illustrate the principles of this utility model, and this utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
