嘉陵江岸边承压式取水工程设计介绍

Introduction of a pressured riverbank water intake project design of Jialingjiang River

以重庆市江北城CBD区域江水源热泵集中供冷供热项目二号能源站取水工程为例,介绍了嘉陵江岸边采用可被江水淹没的封闭承压式取水方式的设计思路、工程特殊性、主要设计内容,以及在狭小空间内采用两级提升解决流量匹配、取水超越管道运行控制、人员交通和设备起吊、特殊情况下的取水头部等设计难点,并针对岸边承压式取水工程设计及运行中发现的问题提出建议。

Taking the No.2power station water intake project in the water source heat pump centralized cooling and heating project for the CBD of Jiangbei zone of Chongqing as example,this paper introduced the design idea,engineering specifications,major design content of the sealedand-pressured water intake station which was located by the Jialingjiang River bank and might be under water in floods.In addition,some design difficulties were also introduced including twostage lifting system in small space to meet the water quantity requirement,operation of water intake by-pass pipe,stuff transportation and device lifting system,and special water intake design,etc..Some suggestions for the problems found in the design and operation of the pressured riverbank water intake project were brought forward as well.
