商丘市睢阳区位于黄淮平原北部,是一个典型的农业区,在该区农用水井分布广、用量大,在农业生产中有着非常重要的作用,长期以来,由于滤水结构的失效,致使水井报废,损失较大。为了改善这种状况,应用了广泛用于水利工程中的土工织物来代替传统的滤水材料,来提高成井质量,减少水流阻力,达到节水的目的。1 技术原理土工织物又称土工布,是以人工合成的高分子化合物为原料,加工成纤维聚合而成,可分为纺土工织物和无纺土工织物 Located in the northern part of the Huang-Huai Plain, Shangyang is a typical agricultural area. The agricultural wells in this area are widely distributed and heavily used. They play a very important role in agricultural production. For a long time, due to the failure of the drainage structure, Wells scrapped, the loss is greater. In order to improve this situation, geotextiles widely used in hydraulic engineering are used instead of the traditional drainage materials to improve the well-forming quality and reduce the water flow resistance so as to save water. 1 Technical Principle Geotextiles, also known as geotextiles, synthetic polymers are raw materials, processed into fibers from polymerization, can be divided into spinning geotextiles and non-woven geotextiles
