自吸真空井,是开采浅层地下水(潜水富水区)比较理想的方式,是能开采地下水为农业灌溉服务的有效措施。实践证明:具有结构简单、节省材料、施工容易、占地少、造价低、见效快,很受农民欢迎。自吸真空井在我县是近年来新开展的水利工程。对它的适应范围,影响半径对井距的确定。井管径大小、深度、滤水器长度(透水孔总面积)和井管外包滤网层数等问题进行测试、探究,取得较明确的数据,为推广使用自吸真空井设计提供依据。
Self-priming vacuum wells, is the exploitation of shallow groundwater (submersible water-rich area) is the ideal way to exploit groundwater for agricultural irrigation services effective measures. Practice has proved that: with a simple structure, material saving, easy construction, small footprint, low cost, quick, very popular with farmers. Self-suction vacuum wells in our county in recent years to carry out the new water conservancy project. The scope of its adaptation, the impact of radius on the determination of well spacing. The diameter and depth of the well, the length of the water filter (the total area of the water permeable hole) and the number of the well pipe outsourcing filter layers are tested and explored to obtain more definite data, which provides the basis for popularizing the design of self-priming vacuum wells.
