无纺土工布材料常用于河道专项治理材料

近年来，土(tu)(tu)工织物已被广(guang)泛(fan)应用于(yu)水(shui)利工程中河堤(di)、护(hu)岸(an)、河道(dao)整治工程及河道(dao)防(fang)渗防(fang)掏刷工程。现场水(shui)利工程中，无纺(fang)土(tu)(tu)工布材(cai)料常用作河道(dao)专项治理(li)材(cai)料，相较于(yu)常规材(cai)料诸如石材(cai)、砌体及混凝土(tu)(tu)，它具有强度较高、耐久性更好、防(fang)渗效(xiao)果(guo)优良等(deng)特点，该材(cai)料虽然具有一定的透(tou)水(shui)性，但满(man)足保水(shui)要求及防(fang)堵(du)塞要求的无纺(fang)土(tu)(tu)工布仅能渗透(tou)通(tong)过土(tu)(tu)体中极为微小的颗粒，因而(er)能有效(xiao)避免河道(dao)流水(shui)对护(hu)岸(an)土(tu)(tu)体的冲(chong)刷。

某工(gong)(gong)(gong)程(cheng)在(zai)多年运(yun)行(xing)过程(cheng)中(zhong)，逐(zhu)渐产(chan)生弯(wan)道(dao)(dao)(dao)水毁及(ji)汊(cha)流问题。在(zai)进行(xing)河流专项治理过程(cheng)中(zhong)，针对(dui)河流沿线(xian)地(di)质多为细砂、石材匮乏、施工(gong)(gong)(gong)期(qi)短问题，合理地(di)应用无纺土工(gong)(gong)(gong)袋丁坝及(ji)无纺土工(gong)(gong)(gong)布(bu)护(hu)岸作为河流弯(wan)道(dao)(dao)(dao)水毁整治措施，并采用土工(gong)(gong)(gong)布(bu)土堤锁坝对(dui)河道(dao)(dao)(dao)汊(cha)流进行(xing)整治，在(zai)完(wan)成河道(dao)(dao)(dao)专项维修养护(hu)工(gong)(gong)(gong)程(cheng)的基础上，有效(xiao)缩(suo)短了施工(gong)(gong)(gong)工(gong)(gong)(gong)期(qi)，并节省(sheng)了工(gong)(gong)(gong)程(cheng)投(tou)资。
