Organism retention device

Abstract

The invention provides an organism retention device. The organism retention device comprises a regulation and storage layer, a filling layer, a planting layer and an impounding layer, the water regulation and storage layer, the filling layer, the planting layer and the impounding layer are arranged from top to bottom in sequence, the device further comprises multiple vertical water absorption materials, the upper end of any water absorption material is located in the planting layer, and the lower end of any water absorption material is located in the impounding layer. According to the organismretention device, the combined structure of the regulation and storage layer, the filling layer, the planting layer and the impounding layer is adopted, the planting layer is arranged at the lower portion of the filling layer, and water-soil loss of the planting layer is effectively reduced; meanwhile, by arranging multiple water absorption materials which are vertically inserted into the planting layer and the impounding layer, rainwater stored in the impounding layer is absorbed into the planting layer, the water needed for the growth of plants in the planting layer is supplemented, it is achieved that the rainwater is automatically recycled and the plants are automatically irrigated, the frequency of manually maintaining the device is effectively reduced, and the maintenance cycle of the device is prolonged.

Description

technical field [0001] The present invention relates to the technical field of bioretention, and more specifically, to a bioretention device. Background technique [0002] With the acceleration of urbanization, problems such as urban waterlogging and black and odorous water bodies have become increasingly prominent, economic losses have become more serious, and the normal life of residents has also been seriously affected. Correspondingly, the concept of "sponge city" with the core of "infiltration, stagnation, storage, purification, utilization, and discharge" and corresponding control measures are also put forward. Among them, bioretention measures not only have good regulation, storage and purification effects, but also have landscape effects, and have been widely used for their efficient water regulation and pollution control functions. [0003] Existing bioretention systems mainly regulate and store and purify runoff rainwater through storage layers, planting soil laye...

Problems solved by technology

However, in the actual operation of the existing bioretention system, because the operation effect of the bioretention facility is closely related to its maintenance, the existing bioretention facility has a higher watering frequency and a shorter maintenance cycle

When bioretention facilities are applied to high flower beds and highway bioretention zones, the maintenance of bioretention facilities is often difficult
