城市下凹立交雨水泵站系统的升级改造

Upgrading and Reconstruction of Rainwater Pumping Station at Urban Underpass

城市下凹立交雨水泵站作为桥区积水的抽升设施,对城市的安全运行起着非常重要的作用。M雨水泵站通过对收水系统、提升系统、退水系统及部分附属设施的全面升级改造,其收集排放雨水的重现期设计标准由P=3年提高至P=10年,设计水量由1.1 m3/s提升至2.2 m3/s。

The rainwater pumping station at urban underpass is the pumping facility for standing water, and it plays a very important role in urban safety. The upgrading and reconstruction of harvesting, pumping and discharging systems and part of ancillary facilities of the Rainwater Pumping Station M were conducted. The design standards of recurrence interval for harvesting and discharging rainwater were improved from P = 3 years to P = 10 years, and the design pumping capacity was improved from Q = 1.1 m^3/s to Q = 2.2 m^3/s.
