防滲膜廠家關于水電站等水利工程中防滲膜的施工中的啟示與建議
1、土(tu)工(gong)(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)施工(gong)(gong)(gong)(gong)(gong)(gong)為精細施工(gong)(gong)(gong)(gong)(gong)(gong)，需要(yao)長期積累經(jing)驗，施工(gong)(gong)(gong)(gong)(gong)(gong)人員(yuan)必須(xu)既掌握土(tu)工(gong)(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)的工(gong)(gong)(gong)(gong)(gong)(gong)程應用原理，又能根據(ju)施工(gong)(gong)(gong)(gong)(gong)(gong)條件處置各種復(fu)雜情況(kuang)!
2、防滲膜(mo)(mo)廠(chang)家對于土(tu)工(gong)膜(mo)(mo)焊接(jie)(jie)、粘接(jie)(jie)等拼接(jie)(jie)工(gong)藝應(ying)展開(kai)較系(xi)統深入的應(ying)用研究，提出(chu)符合我(wo)國(guo)材(cai)料、施工(gong)機具及(ji)施工(gong)環境的施工(gong)導(dao)則!
3、水電站工(gong)(gong)程(cheng)施(shi)工(gong)(gong)是土工(gong)(gong)膜防(fang)滲工(gong)(gong)程(cheng)建設的關鍵環節，土工(gong)(gong)膜施(shi)工(gong)(gong)質(zhi)量(liang)(liang)標準是促進施(shi)工(gong)(gong)工(gong)(gong)藝研(yan)究(jiu)和質(zhi)量(liang)(liang)控制措施(shi)研(yan)究(jiu)的原動力，必(bi)須予(yu)以高度(du)重視(shi)!
4、防滲膜廠(chang)家對于土工膜的(de)錨固、鋪設等(deng)環(huan)節的(de)施工工藝，應展開普遍的(de)工程調查，并(bing)結合室內(nei)試驗和分析計算，形成可(ke)靠(kao)的(de)、完整的(de)工藝方法!
5、土工(gong)膜防滲(shen)工(gong)程的(de)(de)現場監測，尤其(qi)是滲(shen)流監測應予以(yi)提倡(chang)，尤其(qi)對水(shui)頭較(jiao)高、工(gong)程規模(mo)較(jiao)大、防滲(shen)要求較(jiao)高的(de)(de)工(gong)程。
防(fang)滲膜(mo)廠家(jia)HDPE土工膜(mo)的鋪設規定(ding)：
1、通常在(zai)拐(guai)角及畸形地段(duan)，應(ying)(ying)是接縫(feng)長(chang)度(du)盡量(liang)減短。除特殊要(yao)求外，在(zai)坡(po)度(du)大于(yu)1：6的斜坡(po)上距頂(ding)坡(po)或應(ying)(ying)力集(ji)中區域1.5米范圍內，盡量(liang)不設焊縫(feng)。
2、HDPE土工膜在鋪設中，應避免產生人為褶皺，溫度較低時，應盡量拉緊，鋪平。
3、HDPE土工膜裁(cai)切之前，應該準(zhun)確丈量其(qi)相關尺(chi)寸，然后按實際裁(cai)切，一般不宜(yi)按圖示尺(chi)寸裁(cai)切，應逐(zhu)片(pian)編號，詳細(xi)記錄在專用表格(ge)上(shang)。
4、鋪(pu)設HDPE土工膜前應由土建工程(cheng)相應的合格驗收證明(ming)文件。
5、鋪設HDPE土工膜時(shi)應(ying)力求焊縫少，在保(bao)證質(zhi)(zhi)量的前提下，盡(jin)量節約原(yuan)材料(liao)。同時(shi)也容(rong)易保(bao)證質(zhi)(zhi)量。
6、膜(mo)與膜(mo)之間接縫(feng)的搭接寬度(du)一(yi)般不小于10cm，通常(chang)就使焊縫(feng)排列方向(xiang)平行于坡度(du)，即沿坡度(du)方向(xiang)排列。
7、HDPE土工(gong)膜(mo)鋪設(she)完成后，應盡量減少在(zai)膜(mo)面上行(xing)走、搬動(dong)工(gong)具等，凡能對(dui)防(fang)滲膜(mo)造成危(wei)害的物件(jian)，均不應放在(zai)膜(mo)上或攜帶在(zai)膜(mo)上行(xing)走，以(yi)免對(dui)膜(mo)造成意外損傷。
