京港澳高速公路南岗洼雨水调蓄泵站设计

对京港澳高速公路南岗洼雨水泵站进行升级改造,使其达到100年一遇排涝标准。工程设计包含新建雨水调蓄泵站及其收水系统的改造,根据现场特殊条件,将雨水调蓄泵站设计为调蓄池后置型,并利用分流井对原泵站和新建泵站进行水量分配。设计贯彻了“低影响开发”及“绿色公路”的设计理念,并在建设过程中避免对现有泵站的影响,保证了高速公路运营安全。

Design of Nangangwa rainwater storage pumping station of Beijing-Hongkong-Macao Highway

Beijing-Hongkong-Macao(Jing-Gang-Ao)Highway Nangangwa storm water station was up graded so as to the recurrence interval for local flooding design can soon reach the once-in-ahundred- year flood.This design included a newly-built rainwater adjusting pump station and the water collection system.In accordance with the special conditions at the spot,the rainwater adjusting pump station was designed at the rear part of the adjusting storage pond,and the former pump station and the newly-built pump station were designed to allocate the amount of water by using the distributing well.This design was done under the concepts of“low impact development“and“green road”,during the construction process,the affect to the existing pumping station was reduced, thus the safe operation of the highway was guaranteed.
