长距离引水是目前解决水危机的方法之一,而管道工程费用在引水工程中所占的比例愈来愈大,合理选择管材、降低造介并确保安全供水是给水行业的一个长期研究的课题。我们结合武汉水司及参与沿海部分地区大口径长距离管道工程设计施工的实践,提出若干问题与大家探讨。 Long-distance water diversion is one of the ways to solve the water crisis at present. However, the proportion of pipeline engineering expenses in water diversion projects is increasing. It is a long-term research topic for the water supply industry to rationally select pipe materials, reduce production costs and ensure safe water supply. . We have combined with the practice of Wuhan Water Division and participated in the design and construction of large-caliber long-distance pipeline projects in some parts of the coastal area and raised some questions to discuss with you.
