供水工程干管连通设计

Design of Main Pipe Connected Water Supply Project

随着现代化建设的发展,人们的生活水平不断提高,社会主义新农村建设的过程中,农村供水问题逐渐凸显出来。农村供水工程在不断地变化和发展的过程中,从传统、简单地以村为单位的集中供水和分散的小规模供水模式逐渐转化成了城乡一体化的自来水供应模式。由于水源直接影响着居民的日常生活,所以加强农村供水工程建设迫在眉睫,而灌区是农村供水工程的重要工程,灌区主要由输水管道组成,干管起到为滴灌系统输送水量的作用。项目区采用两级干管:主干管和分干管,主干管由一条管线构成,分干管由若干条管线组成。项目区为某灌区供水工程,根据工程地质、气象、概况等情况,对干管连通供水工程进行设计,使设计流量可以满足其控制区域所有灌溉系统的同时工作需要。

With the development of modernization and the continuous improvement of people’s living standards, the problem of rural water supply has gradually emerged in the process of socialist new rural construction. In the process of continuous change and development, the rural water supply project has been gradually transformed from small-scale water supply mode with village as the unit, which is traditional and simple centralized and decentralized, into urban and rural integration of tap water supply model. As the water source directly affects the daily life of residents, it is extremely urgent to strengthen the construction of rural water supply projects. The irrigation area is an important project of rural water supply projects. The irrigation area is mainly composed of water pipelines, whose main pipe plays the role of transporting water for the drip irrigation system. The two-stage main pipe is adopted in the project area, which includes main pipe and branch pipe. The main pipe is composed of one pipeline and the branch pipe is composed of several pipelines. The project area is a water supply project in an irrigation area. According to the engineering geology,meteorology and general situation, the main pipe connected with the main pipe is designed, so that the design flow can meet the working requirement when all irrigation systems in the control area work at the same time.
