目前(qian)土(tu)工(gong)(gong)(gong)(gong)膜的應(ying)用領域(yu)非常(chang)廣泛(fan)，對于鋪設土(tu)工(gong)(gong)(gong)(gong)膜施(shi)工(gong)(gong)(gong)(gong)要求(qiu)越來越高，只(zhi)有做好土(tu)工(gong)(gong)(gong)(gong)膜的質(zhi)量(liang)檢(jian)測、前(qian)期準備工(gong)(gong)(gong)(gong)作以及施(shi)工(gong)(gong)(gong)(gong)中(zhong)(zhong)拼(pin)接工(gong)(gong)(gong)(gong)作，才能保證(zheng)工(gong)(gong)(gong)(gong)程質(zhi)量(liang)。土(tu)工(gong)(gong)(gong)(gong)膜在公路路基(ji)中(zhong)(zhong)的施(shi)工(gong)(gong)(gong)(gong)質(zhi)量(liang)控制為了保證(zheng)土(tu)工(gong)(gong)(gong)(gong)膜在公路路基(ji)中(zhong)(zhong)的應(ying)用效果(guo)，應(ying)該對其(qi)施(shi)工(gong)(gong)(gong)(gong)質(zhi)量(liang)嚴格把控。

　　一要做好(hao)質量檢測工作(zuo)。

　　在選擇土(tu)工(gong)(gong)膜(mo)(mo)時，要對土(tu)工(gong)(gong)膜(mo)(mo)進行各項(xiang)技術指標應采用隨機抽取的(de)(de)方式檢(jian)測每一(yi)個(ge)進貨(huo)批次的(de)(de)樣品質量(liang)，剔(ti)除(chu)不(bu)合(he)格的(de)(de)土(tu)工(gong)(gong)膜(mo)(mo)。

　　第二施工前將施工組織設計和施工作(zuo)業指導書準備好(hao)。

　　施工前，對項目(mu)的地形以(yi)及土壤情況等進行綜合分析，結合工程(cheng)(cheng)項目(mu)的實(shi)際需求和情況，向(xiang)生產廠(chang)商(shang)進行詳細咨詢，確保施工方案的科(ke)學性、合理性，在施工過程(cheng)(cheng)中，要(yao)明(ming)確施工的重(zhong)點，對施工重(zhong)點進行監督，保證土工膜的正確鋪設。

　　第三(san)施工(gong)前，試(shi)焊操作(zuo)土工(gong)膜(mo)的(de)焊接。

　　在(zai)對土工(gong)(gong)膜進(jin)行(xing)拼接前，要(yao)與生(sheng)產(chan)廠商進(jin)行(xing)溝(gou)通(tong)，生(sheng)產(chan)廠家派技術人(ren)員為(wei)施工(gong)(gong)人(ren)員詳細(xi)介紹爬焊機的性能(neng)特點(dian)，讓施工(gong)(gong)人(ren)員能(neng)在(zai)施工(gong)(gong)時根據其(qi)行(xing)走速度和施焊溫度靈活(huo)操作施工(gong)(gong)。

　　第四(si)檢測土(tu)工膜(mo)的焊接質(zhi)量。

　　施(shi)工(gong)中，通(tong)過檢(jian)(jian)(jian)測及(ji)時解決土工(gong)膜的(de)焊接問題(ti)，對于(yu)破損的(de)土工(gong)膜，要予以(yi)(yi)修補。現(xian)場檢(jian)(jian)(jian)測，有兩(liang)個檢(jian)(jian)(jian)測方法(fa)，一是目測;二是充氣檢(jian)(jian)(jian)測。為了保險起見，先用(yong)頭一種實施(shi)檢(jian)(jian)(jian)測，再用(yong)第二種進行檢(jian)(jian)(jian)測。目測，即查看焊縫的(de)完(wan)整度，如若存在漏接、燙損、褶皺以(yi)(yi)及(ji)空腔寬度不均勻(yun)的(de)現(xian)象，應以(yi)(yi)指出(chu)。充 氣檢(jian)(jian)(jian)測，即封閉待測焊縫兩(liang)端(duan)，按照0.1MPa～0.15MPa的(de)標準用(yong)氣針充氣，查看60s，確認壓力(li)表壓力(li)值。

　　第五施工要(yao)在干(gan)燥晴朗的白(bai)天進(jin)行，不能(neng)選擇下雨或者(zhe)晚上進(jin)行，以免由于天氣原因對鋪設質量造成(cheng)影響。土(tu)工膜鋪設的每(mei)個段落要(yao)控制在250~300m之間。

　　第六，抽樣檢測

　　對鋪設(she)完成(cheng)(cheng)的(de)土工膜進行(xing)抽樣檢測(ce)，施(shi)工進行(xing)中的(de)破損和接縫(feng)位置，以確保整(zheng)個工序的(de)完整(zheng)性和完成(cheng)(cheng)度。
