Pipe net of sloping field spray-irrigation system project and pipeline design improving method

Abstract

The invention provides a pipe net of a sloping field spray-irrigation system project and a pipeline design improving method. The invention analyzes the pressure characteristics of the sloping field spray-irrigation pipe net aiming at the remarkable terrain characteristics of high terrain and low water source of a sloping field irrigation region and provides a distribution method of a pipeline of the sloping field spray-irrigation system project and a design method of the sloping field spray-irrigation system project. A machine-pressing spray-irrigation tree-shaped pipe net optimizing model isestablished, investment of the pipe network and minimum operation management cost are taken as targets, the length of a standard pipe size and the pump head are taken as decision variables, and integer coding is adopted. Based on an empirical design, a distribution manner of the pipe net is known, the pipe net model is optimized and calculated by virtue of an evolutionary algorithm, and pipe diameters of partial pipe sections are optimized, so that the investment of the pipe network is saved, the utilization efficiency of the pipe net is improved, and the spray-irrigation quality of the sloping field spray-irrigation system project is improved.

Description

technical field [0001] The invention relates to a slope field sprinkler irrigation system engineering pipe network, in particular to a slope field sprinkler irrigation system engineering pipe network and a pipeline design improvement method, and belongs to the technical field of slope field sprinkler irrigation engineering pipe network. Background technique [0002] Agriculture plays a pivotal role in today's social and economic development, especially in the economically underdeveloped mountainous areas. Only by solving the three rural issues reasonably can we escort the stable development of the social economy. Through the transfer of rural land, make full use of idle barren hills and sloping fields, plant commercial crops on a large scale, and develop a modern agricultural economy. Through the development of water-saving and efficient irrigation technology, not only crop yield and quality can be improved, but also good social benefits can be generated. Water is a preciou...
