无纺布是多种土工织物中用途最广的一种,具有强度高、寿命长、抗老化、耐酸碱、成本低的优点。它代替砂石料用作水利工程中的滤层,具有明显的实用价值和经济效益。黑龙江省汤原县从1987年开始,在水利工程护坡上采用无纺布做垫层,当年应用790平方米。由于效果很好,1990年扩大应用为1,610平方米,四年合计应用2,680平方米。无纺布的推广应用大大改善了水利工程施工条件,加快了工程进度,节省了工程成本。近三年,全县水利工程由于采用无纺布做垫
Non-woven fabric is the most widely used in a variety of geotextile, with high strength, long life, anti-aging, acid and alkali, low cost advantages. It instead of sand and gravel used as a filter layer in water conservancy projects, has obvious practical value and economic benefits. Tangyuan County, Heilongjiang Province from 1987 onwards, in the water conservancy project to use non-woven fabric cushion, then the application of 790 square meters. As a result of good results, the expanded application in 1990 was 1,610 square meters, with a total of 2,680 square meters for four years. The popularization and application of non-woven fabrics have greatly improved the construction conditions of water conservancy projects, accelerated the progress of the projects and saved the engineering costs. In the past three years, the county water conservancy project due to the use of non-woven mat
