It can be understood that the number and size of the drain openings 21 and the size of the drain openings 22 are considered to meet the requirements of the bottom of the drain member 20 according to the amount of sewage, the elastic member 30, the weight variation, and the like. And a blocking member 31 is provided at one side of the drain member 20 and the rainwater pipe 12 to prevent the sewage from being directly drained into the rainwater pipe 12.

Continuing to refer to fig. 4, the drainage principle of the existing urban road drainage system is disclosed. The two sides of the road are provided with the shops which are close to the street, the shops which are close to the street are provided with the confluence pipeline 11, sewage is discharged into the drainage well 10, the existing drainage well 10 is only communicated with the rainwater pipe 12, namely the existing drainage well 10 is formed by converging the sewage of the shops which are close to the street and ground rainwater, and mixed flow water is collected into the drainage well 10 and discharged through the rainwater pipe 12. According to the current urban road regulations, pollution discharge and rainwater drainage separation are required.

Continuing to refer to fig. 5, the drainage principle of the drainer of the drainage well 10 of the present invention is illustrated. Firstly, a sewage pipe 13 and a rainwater pipe 12 are arranged to form two pipelines. The sewage pipe 13 is arranged at the lower part, so that flowing water from a shop or rainwater on the ground can directly flow into the sewage pipe 13, and the sewage pipe 13 and the rainwater pipe 12 can perform their functions under different conditions to solve the problem. The invention is provided with a lifting drainage device. In the initial state, i.e., the first state, the elastic member 30 makes the blocking member 31 close the rainwater passage in the natural state. Under the normal condition of no rain or the initial stage of rain, the sewage from the street shop and the rain water from the initial stage of rain are discharged into the drainage well 10 through the upstream drainage pipe or water inlet of the street shop, and at this time, the water enters the bottommost sewage pipe 13 through the drainage port 21 of the drainage member 20. Under the condition of large rainfall, rainwater is drained into the inside of the drainage well 10 through an upstream near-street shop drainage pipe or a water inlet, at the moment, the water quantity exceeds the drainage quantity of the drainage port 21 of the drainage member 20, when the drainage member 20 is gradually filled with water, the drainage member 20 starts the elastic member 30 under the action of weight after reaching the early warning quantity, the drainage member 20 moves downwards to the bottom of the drainage well 10, at the moment, the elastic member 30 is in a stretched state, the bottom plate of the bottom structure of the drainage well 10 covers the drainage port 21 for drainage, namely, the bottom of the drainage member 20 is the bottom plate attached to the bottom structure of the drainage well 10 or only small gaps are reserved, so that the bottom plate blocks the drainage port 21 for drainage, the drainage port 21 cannot drain water or the drainage quantity of the drainage port 21 is reduced to be very small. The barrier 31 also follows the descent at this time, thereby opening the rainwater passage and discharging a large amount of rainwater from the rainwater pipe 12. When raining becomes or listening to rain, water in the drainage well 10 is gradually drained by the rainwater pipe 12, when the drainage well 10 reaches the water level line, the rainwater pipe 12 cannot continuously drain, at the moment, more water is stored in the drainage member 20, so that the drainage member 20 is continuously influenced by the weight of the water and is also positioned at the bottom of the drainage well 10, at the moment, the water slowly drains into the sewage pipe 13 from the drainage port 22 at the side part of the drainage member 20, the water level line gradually descends to the lowest position of the drainage port 22, at the moment, the drainage member 20 rises to the initial position due to the restoring force of the elastic member 30, and the blocking member 31 closes the rainwater channel.

The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts of the present invention. It should be noted that there are no specific structures but a few objective structures due to the limited character expressions, and that those skilled in the art may make various improvements, decorations or changes without departing from the principle of the invention or may combine the above technical features in a suitable manner; such modifications, variations, combinations, or adaptations of the invention using its spirit and scope, as defined by the claims, may be directed to other uses and embodiments.
