Description

Siphoning type floor drain and grid type rainwater recovery system

Technical Field

The utility model relates to a facility is retrieved to ground rainwater and relevant part, especially the rainwater on basement roof soil layer retrieves facility.

Background

The method has the advantages that the sponge city construction is promoted, urban waterlogging is effectively prevented and treated, urban ecological safety is guaranteed, water resources are conserved, novel urbanization quality is improved, and the concept of harmonious development of human and nature is promoted, so that the method is in line with the spirit of the guide opinions about promoting the sponge city construction in the office hall (2015) 75 of the state institute.

Compared with the country, the city has the common characteristics that the roof and the hard road surface are more, the vegetation, the soft soil area and the natural water storage and drainage facilities of rivers and lakes are relatively few, and if the artificial drainage facilities are incompletely constructed or lack of functions, the artificial drainage facilities are exposed to heavy rain and heavy rain, the phenomenon of local or large-area water logging is easily caused. One meaning of sponge city is that the city has good water absorbing, storing and releasing functions like sponge. The core of the sponge city lies in the effective absorption, storage and utilization of rainwater in the city, water absorption, water storage, water seepage and water purification in the rainy day, and the 'release' of the stored water is utilized when needed.

The grid type rainwater recovery system mainly aims at facilities of water absorption, water seepage and water storage of top surface soil layers and greening soil layers of underground buildings such as an underground garage and the like, and has the function of draining, recovering and storing rainwater rapidly and orderly for utilization.
