Abstract
The invention relates to an integral irrigation and drainage pipeline system. The integral irrigation and drainage pipeline system is characterized in that irrigation pipelines are penetratingly arranged in drainage pipelines and are integrated with the drainage pipeline to form farmland integral drainage and water collection pipe and water delivery pipe main pipelines; prefabricated concrete four-way anchor piers are arranged on the main pipelines in a sectioned manner, two other opposite ends of each prefabricated concrete four-way anchor pier are butted to the corresponding drainage pipeline and the corresponding irrigation pipeline of a branch pipeline and are integrated with the corresponding drainage pipeline and the corresponding irrigation pipeline to form a farmland integral drainage and water collection pipe and water delivery pipe branch pipeline; prefabricated concrete three-way anchor piers are arranged on the various farmland integral drainage and water collection pipe and water delivery pipe branch pipelines at intervals, water supply vertical pipes are arranged on water supply vertical pipe passing holes in the prefabricated concrete three-way anchor piers, and water supply hydrants are mounted on the water supply vertical pipes. The integral irrigation and drainage pipeline system has the advantages that two pipe networks can be nested with each other, the utilization coefficient of irrigation water can be increased, good drainage and waterlogging reduction effects can be realized, and the integral irrigation and drainage pipeline system has good ecologicaland economical benefits for salinized farmland improvement.
Description
technical field [0001] The invention belongs to the technical field of agricultural water and soil engineering and the technical field of soil improvement, and in particular relates to an integrated irrigation and drainage pipeline system and a construction method for saline-alkali farmland. Background technique [0002] In the improvement of saline-alkali land and the construction of farmland water conservancy projects in saline-alkali land, in order to irrigate crops, irrigate salt pressure, and drain water to reduce waterlogging, it is generally necessary to bury irrigation pressure pipes and drainage hidden pipes (seepage pipes) respectively. Irrigation pipes are used for irrigation and salt pressing, and drainage pipes are used to remove groundwater and lower the excessively high water table. Irrigation pipes and drainage pipes use different pipe materials, different buried depths, different pipe diameters (drainage pipes have large diameters), and different buried dept...
