Description

Technical Field

[0001] The utility model relates to the technical field of sponge city construction, and in particular to a sponge city infiltration and drainage structure. Background Art

[0002] Sponge city means that the city can adapt to environmental changes and respond to natural disasters like a sponge, absorbing, storing, infiltrating and purifying water when it rains, and releasing and utilizing the stored water when needed. The construction of sponge city should follow the principle of ecological priority, combining natural methods with artificial measures, and maximize the accumulation, infiltration and purification of rainwater in urban areas on the premise of ensuring the safety of urban drainage and flood prevention, so as to promote the utilization of rainwater resources and the protection of ecological environment.

[0003] A sponge city drainage structure mentioned in the existing Chinese public patent (authorization announcement number: CN218713696U) relates to the field of urban construction technology, improves the existing city drainage shaft, the manhole cover above the usual hinged connection, when the water on the road needs to be quickly drained, the manhole cover is fully opened, which is prone to potential safety hazards, including a drainage shaft opened on the ground, the top of the drainage shaft is fixedly installed with a mounting frame, the inside of the mounting frame is installed with a manhole cover, and the manhole cover is provided with a drainage hole; the bottom of the mounting frame is rotatably installed with a rotating shaft, the bottom of the mounting frame is fixedly installed with a motor, and the output end of the motor is fixedly connected to one end of the rotating shaft. The utility model drives the rotating shaft to rotate by a motor, so that the two screw sleeves move relative to each other, so that the manhole cover is separated from the mounting frame, and the water on the road is quickly drained. Compared with the traditional method of directly flipping and opening the manhole cover for drainage, this method reduces the occupation of road space.

[0004] At present, urban infiltration and drainage also use drainage wells to alleviate flooding. However, when rainwater enters the well, it will carry the garbage remaining on the road into the well, causing blockage in the well and making it impossible to drain the water, affecting the infiltration and purification of rainwater. In actual use, the above patent cannot clean the garbage in the well in time.

[0005] For this purpose, a sponge city infiltration and drainage structure is proposed. Utility Model Content
