受跨河工程影响的河道输水研究

Study on Water Conveyance in River Channel Affected by River-crossing Project

为解决跨河工程中工程建设和河道输水相互制约的问题,以某商业综合体项目为背景,通过河道分区通流、河道绕流和布管引流这3种方案的比选,最终采用了布管引流的方法。通过管径计算,设置伸缩节、法兰和柔性接头等技术措施,加以管道敷设,成功解决了工程建设和河道输水同步进行的问题,实现了下游供水和清流的目标,取得了良好的社会效益,为类似跨河工程的建设提供了参考。

In order to solve the problem of mutual restriction between engineering construction and river water conveyance in a river-crossing project,taking a commercial complex project as the background,the method of pipe drainage was finally adopted through the comparison and selection of three schemes,namely,river flow through zoning,river flow around and pipe drainage.Through pipe diameter calculation,setting expansion joints,flanges,flexible joints and other technical measures,as well as pipeline laying,the problem of synchronization between engineering construction and river water conveyance was successfully solved,the goal of downstream water supply and clean flow was realized,and good social benefits were achieved,which provided a reference for the construction of similar rivercrossing projects.
