土工膜需要针对不同地区的地质条件和施工难度进行施工

利用复合土(tu)工(gong)(gong)膜(mo)的(de)(de)防渗效果，需(xu)要针(zhen)对不同地区的(de)(de)地质条(tiao)件和(he)(he)施(shi)工(gong)(gong)难度进行适当的(de)(de)调整和(he)(he)改(gai)进。在湖(hu)区防渗施(shi)工(gong)(gong)中，我们可以借鉴以往(wang)的(de)(de)成功经验(yan)，但也不能(neng)盲目套用，还(hai)需(xu)要结(jie)合实际(ji)情(qing)况进行分析和(he)(he)判(pan)断。只有(you)通过(guo)合理的(de)(de)设计和(he)(he)施(shi)工(gong)(gong)方法，才能(neng)充分发挥复合土(tu)工(gong)(gong)膜(mo)的(de)(de)优势，达到最佳的(de)(de)防渗效果。

为了提升(sheng)复合土工(gong)膜(mo)的(de)防渗效果并确保(bao)施工(gong)的(de)连续(xu)性，以(yi)提高施工(gong)效果，在正式施工(gong)前(qian)需认(ren)真准备。

（1）在进(jin)(jin)行(xing)(xing)复(fu)合土(tu)工(gong)(gong)(gong)膜施(shi)(shi)工(gong)(gong)(gong)之前，需要进(jin)(jin)行(xing)(xing)适当(dang)的(de)技能(neng)技术(shu)培(pei)训。为了确保施(shi)(shi)工(gong)(gong)(gong)质量，我们会(hui)邀请(qing)复(fu)合土(tu)工(gong)(gong)(gong)膜生产制(zhi)造厂家的(de)专业技术(shu)人(ren)员(yuan)对施(shi)(shi)工(gong)(gong)(gong)人(ren)员(yuan)进(jin)(jin)行(xing)(xing)培(pei)训，确保每(mei)位施(shi)(shi)工(gong)(gong)(gong)人(ren)员(yuan)都能(neng)熟(shu)练掌握复(fu)合土(tu)工(gong)(gong)(gong)膜的(de)施(shi)(shi)工(gong)(gong)(gong)技巧和注意事项。

（2）在(zai)正式进(jin)行(xing)(xing)复合(he)土工(gong)(gong)(gong)(gong)膜施工(gong)(gong)(gong)(gong)之前，必须做好施工(gong)(gong)(gong)(gong)场地的准备工(gong)(gong)(gong)(gong)作。在(zai)此之前，需(xu)要向监理(li)工(gong)(gong)(gong)(gong)程师申(shen)请对基础面进(jin)行(xing)(xing)联(lian)合(he)检查验收工(gong)(gong)(gong)(gong)作，只有在(zai)全(quan)部(bu)验收合(he)格(ge)后，才能(neng)开始进(jin)行(xing)(xing)复合(he)土工(gong)(gong)(gong)(gong)膜施工(gong)(gong)(gong)(gong)。

（3）加(jia)强(qiang)对原(yuan)材料的(de)检验。如果(guo)复合(he)土(tu)工(gong)膜自身(shen)存在质(zhi)(zhi)量(liang)(liang)问题，无论选择何种施(shi)工(gong)技术，都无法保(bao)(bao)证最终的(de)施(shi)工(gong)效果(guo)。因此，在复合(he)土(tu)工(gong)膜进(jin)入施(shi)工(gong)现(xian)场(chang)后(hou)，必须严格(ge)按照相(xiang)关规范(fan)和标(biao)准进(jin)行抽样检验，坚决杜绝质(zhi)(zhi)量(liang)(liang)不(bu)符合(he)标(biao)准的(de)复合(he)土(tu)工(gong)膜用于湖(hu)区防渗施(shi)工(gong)。就案例工(gong)程而言，要(yao)求复合(he)土(tu)工(gong)膜的(de)单位面积质(zhi)(zhi)量(liang)(liang)为(wei)800克/平方米，厚(hou)度为(wei)0.4毫(hao)米，断裂强(qiang)度不(bu)低(di)于16千牛/米，CBR顶破强(qiang)力不(bu)低(di)于2.8千牛，撕破强(qiang)力不(bu)低(di)于0.56千牛，断裂伸长率不(bu)低(di)于70%，以(yi)便(bian)从根(gen)本上保(bao)(bao)证湖(hu)区防渗施(shi)工(gong)质(zhi)(zhi)量(liang)(liang)。
