土(tu)工(gong)布(bu)(bu)(bu)又稱土(tu)工(gong)織(zhi)物，它是由合(he)成纖維通過(guo)針(zhen)刺或編織(zhi)而成的透水性土(tu)工(gong)合(he)成材料。成品為布(bu)(bu)(bu)狀，一般(ban)寬度(du)為4-6米，長度(du)為50-100米。土(tu)工(gong)布(bu)(bu)(bu)分為有(you)紡土(tu)工(gong)布(bu)(bu)(bu)和無(wu)紡土(tu)工(gong)布(bu)(bu)(bu)。土(tu)工(gong)布(bu)(bu)(bu)具有(you)優秀的過(guo)濾、隔(ge)離、加固防護作用、抗(kang)拉強度(du)高(gao)、滲(shen)透性好、耐(nai)高(gao)溫、抗(kang)冷凍(dong)、耐(nai)老化、耐(nai)腐蝕。

土工(gong)(gong)布主要有(you)六(liu)大功能：1.隔離 2.過濾 3.排水(shui)(shui)(shui) 4.加筋(jin) 5.防(fang)(fang)護 6.封閉。可應用于四(si)大領域1、水(shui)(shui)(shui)利工(gong)(gong)程(cheng)：海堤(di)、江(jiang)堤(di)、湖堤(di)達(da)標工(gong)(gong)程(cheng)；水(shui)(shui)(shui)庫加固(gu)工(gong)(gong)程(cheng)；圍墾工(gong)(gong)程(cheng)；防(fang)(fang)汛搶險(xian)。 2、公路鐵路航空(kong)港(gang)工(gong)(gong)程(cheng)：軟基加固(gu)處理；邊(bian)坡(po)防(fang)(fang)護；路面防(fang)(fang)反射裂(lie)縫結(jie)構(gou)層(ceng)；排水(shui)(shui)(shui)系統；綠化(hua)隔離帶。3、電工(gong)(gong)工(gong)(gong)程(cheng)：核電站(zhan)基礎工(gong)(gong)程(cheng)；火電灰壩(ba)工(gong)(gong)程(cheng)；水(shui)(shui)(shui)電站(zhan)工(gong)(gong)程(cheng)。4、港(gang)口航道(dao)工(gong)(gong)程(cheng)：港(gang)口。你所說的透(tou)水(shui)(shui)(shui)就是(shi)排水(shui)(shui)(shui)吧。是(shi)為了排除多余的水(shui)(shui)(shui)分，防(fang)(fang)止水(shui)(shui)(shui)土流失！
