长距离输水管道设计方案

Design Scheme of Long-distance Water Conveying Pipe

在给水工程中,有时会出现长距离输水管道,长度可达十几公里,乃至几十公里。可能途径河流、山谷、丘陵、公路、铁路等障碍物,可能出现地下水、岩石、空洞等地质条件,可能出现几百米的高差,可能设数个加压泵站,设计比较复杂。该文对长距离输水管道设计方案中有关选线、输水管道、加压泵站等问题作了阐述。

In the water supply engineering,there will be the long-distance water conveying pipes with the length from several ten km.to tens km,which will pass the barriers of rivers,valleys,hills,highways,railways and so on,will meet with the geological conditions of underground water,racks,hollows and so on,and there will be several hundred meters of height difference and several booster pumping stations to be constructed along the line.Its design is more complicated.The article sets forth the line selection,water conveying pipe,booster pumping station and so on in the design scheme of long-distance water conveying pipe.
