一、长距离输水管道设计的原则:液体的长距离管道输送是一种发展十分迅速的运输方式。在供水行业中,由于新水源地的开发,取水和用水地距离增加,长距离输水管道发展也同样十分迅速。以天津为例,在近十五年中,由于浜海地区经济发展,已铺设了4条直径D1200mm 源水输水管,每一条长度都超过40Km。最近,还拟新铺设3条。如何在满足使用条件下降低工程
First, the principle of long-distance water pipeline design: long-distance liquid pipeline is a very rapid development of transport. In the water supply industry, due to the development of new water sources, the distance between water withdrawal and water use has increased, and the development of long-distance water pipelines has also been very rapid. Take Tianjin as an example. In the past 15 years, due to the economic development in Binhai, four D1200mm diameter water supply pipes have been laid, each with a length of more than 40Km. Recently, it plans to lay out three new. How to reduce the use of the project to meet the conditions
