HDPE土工膜的(de)施工方法
首先，HDPE土工膜進行(xing)(xing)將(jiang)(jiang)施工(gong)現(xian)場的地基清理找平夯實，不得有樹根、石(shi)子等硬物(wu)內，以免(mian)硌壞土(tu)工(gong)膜(mo)，其容次將(jiang)(jiang)將(jiang)(jiang)土(tu)工(gong)膜(mo)從坡上往下滾鋪，沿(yan)一定方向(xiang)鋪設，土(tu)工(gong)膜(mo)與(yu)土(tu)工(gong)膜(mo)的直接(jie)(jie)的搭(da)接(jie)(jie)不低于10公(gong)分(fen)，土(tu)工(gong)膜(mo)與(yu)土(tu)工(gong)膜(mo)的接(jie)(jie)觸面應(ying)用布擦拭干凈再焊，用爬(pa)焊機焊接(jie)(jie)，這(zhe)里的爬(pa)焊機又叫雙軌熱熔(rong)焊接(jie)(jie)機，焊接(jie)(jie)完畢后，要(yao)進行(xing)(xing)檢測。
HDPE土(tu)(tu)工膜和土(tu)(tu)工布(bu)的區別
HDPE土工(gong)(gong)(gong)(gong)(gong)膜(mo)又(you)叫hdpe土工(gong)(gong)(gong)(gong)(gong)膜(mo)，具有防滲(shen)、隔(ge)(ge)離(li)(li)的(de)特點(dian)，是由聚乙(yi)(yi)烯(xi)樹脂(zhi)顆(ke)粒(li)為原(yuan)(yuan)料加工(gong)(gong)(gong)(gong)(gong)而(er)成(cheng)；而(er)土工(gong)(gong)(gong)(gong)(gong)布(bu)具有透水(shui)不透土的(de)功能，跟防滲(shen)膜(mo)恰(qia)恰(qia)相反；兩(liang)者的(de)原(yuan)(yuan)材料不同，土工(gong)(gong)(gong)(gong)(gong)膜(mo)的(de)是聚乙(yi)(yi)烯(xi)塑(su)料顆(ke)粒(li)，而(er)土工(gong)(gong)(gong)(gong)(gong)布(bu)的(de)則(ze)是滌(di)綸或丙(bing)綸短纖維；兩(liang)者的(de)生產工(gong)(gong)(gong)(gong)(gong)藝(yi)不一樣，土工(gong)(gong)(gong)(gong)(gong)膜(mo)通國淋膜(mo)機(ji)壓延(yan)工(gong)(gong)(gong)(gong)(gong)藝(yi)和吹膜(mo)吹塑(su)法工(gong)(gong)(gong)(gong)(gong)藝(yi)加工(gong)(gong)(gong)(gong)(gong)，而(er)土工(gong)(gong)(gong)(gong)(gong)布(bu)則(ze)是在無紡梳理(li)機(ji)梳理(li)、反復針(zhen)刺而(er)成(cheng)；兩(liang)者的(de)應用(yong)(yong)范圍不同，土工(gong)(gong)(gong)(gong)(gong)膜(mo)主(zhu)要應用(yong)(yong)于(yu)垃圾(ji)場、礦場、池子(zi)的(de)防滲(shen)、隔(ge)(ge)離(li)(li)；而(er)土工(gong)(gong)(gong)(gong)(gong)布(bu)則(ze)主(zhu)要用(yong)(yong)于(yu)堤壩護坡、市政、地下隧道等工(gong)(gong)(gong)(gong)(gong)程。
當然(ran)土(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)和土(tu)(tu)工(gong)(gong)(gong)膜可(ke)以搭(da)配使(shi)用(yong)在垃圾場、石油化工(gong)(gong)(gong)等(deng)(deng)工(gong)(gong)(gong)程(cheng)中，土(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)和防滲膜可(ke)以經過特殊工(gong)(gong)(gong)藝復合成(cheng)復合土(tu)(tu)工(gong)(gong)(gong)膜，復合土(tu)(tu)工(gong)(gong)(gong)膜分兩(liang)布(bu)(bu)一(yi)膜、一(yi)布(bu)(bu)一(yi)膜等(deng)(deng)，主要用(yong)于河(he)道治理(li)、礦區、人工(gong)(gong)(gong)湖等(deng)(deng)環保(bao)領域。
