Embodiment Construction

[0138] Below in conjunction with the accompanying drawings, the technical solutions of the slope field sprinkler irrigation system engineering pipeline network and pipeline design improvement method provided by the present invention will be further described, so that those skilled in the art can better understand the present invention and be able to implement it.

[0139] When the surface slope exceeds 6%, it is more difficult to use traditional surface irrigation. Due to the influence of terrain undulations and slopes, slope field sprinkler irrigation systems are more cumbersome and complicated than flat fields in terms of engineering design parameter settings, planning and design methods, and operation management. Planning a water-saving and efficient irrigation project for sloping fields and providing guaranteed irrigation conditions for large-scale and intensive economic crops is an effective way to develop characteristic agriculture. The present invention focuses on the o...

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...
