Lining method for farmland ecological drainage ditch
The invention relates to a lining method for a farmland ecological drainage ditch. The lining method comprises the steps that a gravel cushion layer is laid at the ditch bottom of the drainage ditch;water-permeable geotechnical cloth is laid along the inner wall of the drainage ditch, and the water-permeable geotechnical cloth covers the gravel cushion layer; and finally, a plurality of prefabricated concrete water-permeable grooves are connected end to end inside the drainage ditch. The prefabricated concrete water-permeable grooves are convenient to construct, stable in structure, durable,facilitates flowing of a water body, not easy to deposit and not easy to break; reserved water-permeable holes are formed, surplus water or too high underground water in farmland soil are drained intothe ditch through the holes, aquatic plants are planted or naturally grow at the reserved water-permeable holes, and the effects of waterlogging control, waterlogging reduction, purifying water quality and improving the ecological environment are achieved; and a novel field drainage ditch hardening lining form is provided, has the advantages of being strong in drainage performance, good in slopeprotection effect and long in service life, has the ecological functions of intercepting and reducing pollution, and provides guarantee measures for farmland waterlogging control, waterlogging reduction and non-point source pollution treatment.
本发明涉及一种农田生态排水沟的衬砌方法，在排水沟的沟底铺设碎石垫层；沿着排水沟的内壁铺设透水土工布，透水土工布将碎石垫层覆盖；最后将多个预制混凝土透水沟槽在排水沟的内部首尾相连。预制混凝土透水沟槽的施工方便，结构稳定，持久耐用，便于水体流动且不易淤积，不易发生折断；设置预留透水孔，有利于农田土壤中盈余水分或过高的地下水通过孔洞排入沟中，预留透水孔处种植或自然生长水生植物，具有除涝、降渍以及净化水质、改善生态环境的作用。本发明提出了一种新型田间排水沟硬化衬砌形式，具有排水性能强、护坡效果好、使用寿命长，且兼具截污减污的生态功能，为农田除涝降渍和面源污染治理提供保障措施。
