Description

An overflow well based on sponge city

Technical field

The utility model relates to the technical field of construction engineering, specifically to an overflow well based on a sponge city.

Background technique

Sponge city is a new generation of urban stormwater management concept. It means that a city can be like a sponge and have good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called a "water-elastic city." Like a sponge, it has good "elasticity" in adapting to environmental changes and responding to natural disasters. The international common term is "low-impact development rainwater system construction". When it rains, it absorbs, stores, seeps, and purifies water. When needed, Release and utilize the stored water to realize the free movement of rainwater in the city. The main function of the overflow well is to control the flow of water. In the sponge city, the overflow well is indispensable. The overflow well needs to be integrated into the sponge city. The excess water during the project will temporarily flow into the natural water body through the overflow pipe in the overflow well (or the sewage will be discharged into the rainwater ditch) to avoid flooding the water collection tank and affecting drainage.

When the rainfall is too heavy, if the rainfall exceeds the bearing capacity of the overflow well, the rainwater will not be discharged in time, and the water flow in the underground drainage pipe will exceed the load. The water will flow back from the overflow well and overflow to the surface, and at the same time, various dirty things in the overflow well will be discharged. Dirty substances are brought to the surface, causing pollution to the surface environment.

In view of this, the present utility model is proposed.

The two second connecting rods 14 are away from the floating plate 12. Baffles 15 are fixedly connected to both sides of the sealing plate 8. The baffles 15 are located below the sealing plate 8. When the water flow exceeds the load, the water located inside the overflow well 2 enters the inside of the buffer tank 10 through the overflow tank 9. The buffer tank 10 collects a part of the water, and as the water enters the inside of the buffer tank 10, the water passes through the inside of the water permeable hole 13, and drives the floating plate 12 to move upward through the water. As the two floating plates 12 move, the two floating plates 12 move upward. A second connecting rod 14 drives the two baffles 15 to move upward, and makes the two baffles 15 fit the sealing plate 8. At this time, the entire collection frame 6 is sealed by the two baffles 15 and the sealing plate 8. The water inside the overflow well 2 is blocked to prevent impurities such as sludge at the bottom of the overflow well 2 from being driven to the ground by the water.

As the water enters the inside of the buffer tank 10, the water flows from The inside of the water permeable hole 13 passes through, and the water drives the floating plate 12 to move upward. As the two floating plates 12 move, the two second connecting rods 14 drive the two baffles 15 to move upward, and the two baffles 15 move upward. 15 is fitted with the sealing plate 8. At this time, the entire collection frame 6 is sealed through the two baffles 15 and the sealing plate 8, and the water inside the overflow well 2 is blocked, thereby avoiding the leakage of water in the overflow well. 2. The sludge and other impurities at the bottom are driven to the ground by water.

Therefore, the overflow well based on the sponge city can filter impurities such as fallen leaves by being provided with a collection frame 6 and a filter hole 7 to avoid the accumulation of impurities such as fallen leaves at the bottom of the overflow well 2. By being provided with an overflow tank 9 and the buffer tank 10, when the water flow exceeds the load, the water can enter the interior of the buffer tank 10, and a part of the water can be stored through the buffer tank 10, and pass through the sealing plate 8, the guide rod 11, the floating plate 12, and the water permeable hole 13 The cooperative arrangement of the second connecting rod 14 and the baffle 15 can seal the collection frame 6 when the amount of water is large, preventing various dirty materials such as sludge at the bottom of the overflow well 2 from being brought to the ground. situation, thus avoiding the pollution caused by dirty substances to the surface environment. The one-way valve 18 can prevent the water located inside the overflow well 2 from entering the inside of the buffer tank 10. The submersible pump 16 and the drainage pipe 17 are provided so that the water located in the overflow well 2 can be prevented from entering the buffer tank 10. The water inside the buffer tank 10 can re-enter the inside of the overflow well 2, preventing water from accumulating inside the buffer tank 10, and ensuring the normal buffering function of the buffer tank 10 when the water flow exceeds the load again.
