Drainage of large and multi-storey underground parking garage design update: In recent years, due to increased gentrification and private car ownership in residential real estate, the construction of one or more layers in the underground parking garage underground, almost all real estate became imitated hot, and there are signs intensified. However, since this part of the building's underground parking garage that is ground elevation is generally lower than the outdoor ground level, its gravity drainage is not discharged into the municipal sewer network, especially heavy rain season, if poorly designed drainage, often causing rain dang plot, the impact of the garage safety and use. In this regard, we must pay more attention to the design. Underground garage waterproofing and drainage due to the underground garage below the ground level outdoor road elevation, so when the road surface to prevent storm water intrusion is the first issue of drainage design, secondly, the open portion of the vehicle entrances rainwater collection, rinse the ground How water sewage, fire fighting hydrant system and sprinkler system when the exclusion is the focus of the drainage design. According to these waterproofing and drainage characteristics, can be determined as follows drainage scheme: in the underground garage entrance from the slope at a certain elevation for processing, and set the first episode water ditches to block the outdoor terrace instantaneous water intrusion; at the entrance slope Road and then set up the second episode lowest water ditches to intercept rainwater at the ramp; located in the underground garage indoor floor drain and drainage collection buried pipe flushing floor drain; set the right amount of collection wells, buried pipe drainage collected by various drainage, and enhance the use of submersible sewage pump discharge.
