摘要
对某工程所用的无纺布进行了物理力学特性试验、渗透性试验和淤堵试验,说明此种无纺布能满足排水要求,且用做反滤层时,不会产生不允许的淤堵现象。
This article analysed the experiments of the characters of physical mechanics, the permeability and the siltation for the nonwoven cloth in a certain project. Based on the analysis, a conclusion is drawn that the nonwoven cloth could satisfy the neen of drainage and could not occure the unallowed siltation phenomenon when it is used for filter.
