為(wei)您介紹品質奧(ao)|特點(dian)多的(de)復(fu)合土工膜|復(fu)合土工膜為(wei)您介紹

　　復合土工膜又(you)(you)有種新型的(de)復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)--經(jing)編(bian)(bian)復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)。經(jing)編(bian)(bian)復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)以(yi)合(he)(he)(he)成纖(xian)維(wei)(wei)(或玻璃纖(xian)維(wei)(wei))為(wei)增強(qiang)材料(liao)，通過與(yu)復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)復(fu)(fu)合(he)(he)(he)而成的(de)新型土(tu)(tu)(tu)工(gong)(gong)(gong)材料(liao)。經(jing)編(bian)(bian)復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)不(bu)(bu)同于一(yi)般復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)。其特點(dian)是經(jing)線(xian)與(yu)緯線(xian)的(de)交叉點(dian)不(bu)(bu)彎(wan)曲，各自處于平(ping)直(zhi)狀(zhuang)態。用(yong)捆綁(bang)線(xian)將(jiang)兩者捆扎牢固，可較均勻同步，承受(shou)外力，分布應力，且當(dang)施(shi)加(jia)的(de)外力撕裂材料(liao)的(de)瞬時(shi)，紗(sha)線(xian)會沿初(chu)裂口擁集，增加(jia)抗撕裂強(qiang)度。復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)經(jing)編(bian)(bian)復(fu)(fu)合(he)(he)(he)時(shi)，即利用(yong)經(jing)編(bian)(bian)捆綁(bang)線(xian)在經(jing)，緯紗(sha)與(yu)短纖(xian)針刺(ci)非織防(fang)(fang)水土(tu)(tu)(tu)工(gong)(gong)(gong)布的(de)纖(xian)維(wei)(wei)層間(jian)反復(fu)(fu)穿(chuan)行，使三(san)者編(bian)(bian)結(jie)為(wei)一(yi)體。因而經(jing)編(bian)(bian)復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)既(ji)具(ju)有高抗拉強(qiang)度，低延伸(shen)率的(de)特點(dian)，又(you)(you)兼(jian)有復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)的(de)防(fang)(fang)水性(xing)能。復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)因此經(jing)編(bian)(bian)復(fu)(fu)合(he)(he)(he)土(tu)(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)是一(yi)種具(ju)在加(jia)筋增強(qiang)、隔離、防(fang)(fang)護作用(yong)的(de)防(fang)(fang)滲材料(liao)。它是當(dang)今上高水平(ping)的(de)應用(yong)土(tu)(tu)(tu)工(gong)(gong)(gong)復(fu)(fu)合(he)(he)(he)材料(liao)。

　　復合(he)(he)土(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)施(shi)工(gong)(gong)(gong)中，首(shou)先要用(yong)(yong)料(liao)徑較小的(de)(de)砂土(tu)(tu)或粘土(tu)(tu)找平基面，然后(hou)再鋪(pu)(pu)設土(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)。土(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)不要繃得太緊(jin)，兩(liang)端埋入(ru)土(tu)(tu)體(ti)部(bu)(bu)分呈波紋狀，復合(he)(he)土(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)。后(hou)在所鋪(pu)(pu)的(de)(de)土(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)上用(yong)(yong)細砂或粘土(tu)(tu)鋪(pu)(pu)一層(ceng)(ceng)(ceng)10cm左右過渡層(ceng)(ceng)(ceng)。砌上20-30cm塊石(或砼(tong)預制塊)作防沖(chong)保護(hu)層(ceng)(ceng)(ceng)。施(shi)工(gong)(gong)(gong)時，應盡力避免石塊直接(jie)(jie)砸在土(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)上，是邊(bian)鋪(pu)(pu)膜(mo)(mo)邊(bian)進行(xing)保護(hu)層(ceng)(ceng)(ceng)的(de)(de)施(shi)工(gong)(gong)(gong)。復合(he)(he)土(tu)(tu)工(gong)(gong)(gong)膜(mo)(mo)與周邊(bian)結構物連接(jie)(jie)應采用(yong)(yong)膨脹螺栓和鋼板(ban)壓(ya)條錨固，連接(jie)(jie)部(bu)(bu)位要涂刷(shua)乳(ru)化瀝(li)青(厚2mm)粘接(jie)(jie)，以防該處(chu)發生滲漏(lou)。
