Abstract

The invention belongs to the technical field of agricultural irrigation and particularly relates to a water-saving irrigation pipeline and a construction method thereof. The water-saving irrigation pipeline comprises a spodosol packing layer which is arranged in a foundation trench and a composite flexible pipe which is fixedly arranged in the spodosol packing layer, wherein the composite flexible pipe comprises a flexible pipe base layer, a PVC (Polyvinyl Chloride) coated layer and a PE (Poly Ethylene) thin-film layer from outside to inside. The construction method comprises the steps of material selection, foundation trench excavation, spodosol slotting, pipe laying, pipeline inspection, water-immersion compacting and the like. According to the water-saving irrigation pipeline, the problems such as pipeline breakage, water exclusion and operation difficulty which are brought by the structure and construction problems in the prior art are solved; the water-saving irrigation pipeline has the advantages of water-saving property, energy-saving property, land-saving property, simplicity and practicability in construction, short construction period and the like, and can be popularized in a large area, so that a new way is provided for saving water for the agriculture in China.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, and in particular relates to a water-saving irrigation pipeline and a construction method thereof. Background technique [0002] my country is a large agricultural country, and agricultural irrigation water accounts for more than 70% of the total water consumption. Therefore, it is a very urgent task for farmland irrigation to realize precise irrigation, save agricultural water resources, and increase agricultural production in irrigation areas. At present, pipeline irrigation is one of the important technologies to realize agricultural water-saving irrigation. Generally speaking, pipeline irrigation can save water by 15% to 30%. [0003] In recent years, various localities and departments have successively developed thin-walled PVC plastic pipes, double-walled corrugated plastic pipes, plastic film-lined outer-protected baking pipes, and buried plastic hoses. Among them, flexibl...
