Description

Technical Field

[0001] This utility model relates to the field of sponge city technology, and in particular to a replaceable sponge city facility sedimentation basket device. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept. Its core lies in mimicking the natural hydrological cycle, constructing a low-impact development stormwater system through six measures: infiltration, retention, storage, purification, utilization, and drainage. This system reduces surface runoff and waterlogging during heavy rains while storing rainwater for use during dry seasons, achieving natural migration and recycling of water resources. Traditional sedimentation basket devices involve casting a rectangular permeable concrete sedimentation basket on-site, lining the inside with 3-5cm of pebbles, and covering it with a maintenance cover. Rainwater from driveways and sidewalks flows into the sedimentation basket, where it is trapped by the pores between the pebbles and the permeable concrete, trapping large amounts of soil and debris. The filtered surface water is then promptly discharged into the municipal sewer network.

[0003] Traditional sedimentation baskets require on-site cleaning that occupies road space, which is inconvenient, time-consuming, and inefficient for maintenance personnel, often resulting in incomplete cleaning and poor effectiveness. Cleaning debris from the gaps between pebbles within the basket is also cumbersome, requiring maintenance personnel to manually remove the pebbles and debris together, clean the debris on the ground, and then place the pebbles back into the basket. This process is tedious, time-consuming, and inefficient for maintenance personnel, occupies road or sidewalk space for extended periods, and yields unsatisfactory results. Therefore, a replaceable sedimentation basket device for sponge city facilities is proposed to improve the efficiency of manual cleaning, shorten maintenance and road occupancy time, reduce maintenance costs, and improve the performance of sponge city facilities.

It should be noted that the precast permeable concrete box can also be composed of five precast concrete slabs. After being brought to the construction site, the construction workers dig the corresponding pits on the side of the municipal drainage well, and then place the precast concrete slabs at the bottom and around the pits respectively, and then fill and compact the soil. This is more conducive to on-site construction and assembly. Attached Figure Description
