随着城市交通建设快速发展,城市中的下穿通道也越来越多,下穿通道内渍水不能自排进入城市雨水管道,一般在下穿通道的最低点设置泵站抽排,通道内雨水经抽排后进入城市雨水管涵。本文主要结合襄阳市东内环、南内环东津段的下穿通道工程,总结了下穿通道水泵房沉井法的应用范围和设计经验。 With the rapid development of urban traffic construction, there are more and more underpass tunnels in the city. The waterlogging in the underpass channel can not be drained into the urban stormwater pipeline. Generally, the pumping station pumping and draining water is provided at the lowest point of the underpass tunnel. After pumping into the city storm water culvert. This paper mainly combined with the underpass tunnel project of Donghuan and Xiannong sections in the south inner ring of Yangyang City, summarizes the application scope and design experience of the sinkhole method of underpass tunnel pump house.
