山家寨输水管道设计及施工

Water transmission pipeline design and construction in Shanjiazhai

为了保证水质和水量,管道输水在水利工程跨区域输水中的运用越来越广。管道输水既能保证水质、减少泄漏,同时又能适应地形起伏,其在输水工程中的优势越来越明显。本文结合夹岩水利枢纽及黔西北供水工程中的山家寨输水管道设计情况,通过对长距离、大管径输水管道的布置,水力计算以及管道敷设设计的介绍,为类似工程提供一定参考。

To ensure water quality and water quantity, applications of pipeline water delivery in crossregional water conservancy projects are more and more extensive, pipeline water delivery can not only ensure the water quality and reduce leakage, but also can adapt to the ups and downs of the terrain, its advantages are more and more obvious. In this paper, design of water transmission pipeline in Shanjiazhai of Jiayan water conservancy and water supply project in Northwest Guizhou including layout of long distance and large diameter pipeline, hydraulic calculation and pipeline laying design is introduced to provide a reference for similar projects.
