  CPVC電(dian)力(li)管(guan)施(shi)工有很多的(de)講究,煙臺(tai)電(dian)力(li)管(guan)廠家為(wei)您分享(xiang)一下吧(ba)。

  先(xian)是(shi)套管選(xuan)擇,通常套管內徑應(ying)大(da)于或(huo)等(deng)于電纜(lan)外(wai)徑的(de)(de)150%.電壓等(deng)級越(yue)高應(ying)選(xuan)用(yong)(yong)較大(da)內徑套管。橫(heng)越(yue)馬(ma)路、橋梁下(xia)方(fang)、河床下(xia)方(fang)等(deng)應(ying)采用(yong)(yong)環剛度(du)(du)等(deng)級高的(de)(de)套管;特殊環境(像是(shi):化工廠)應(ying)選(xuan)用(yong)(yong)高環剛度(du)(du)管材;綠(lv)化帶、居民區、人行道下(xia)、工礦企業非行車道下(xia)可(ke)選(xuan)用(yong)(yong)環剛度(du)(du)較小的(de)(de)套管,可(ke)節省投入。

   施(shi)工時(shi)溝(gou)漕的(de)開(kai)挖(wa)要按設(she)(she)計單(dan)位的(de)設(she)(she)計開(kai)挖(wa),溝(gou)底應整平夯實,再均(jun)勻鋪(pu)設(she)(she)一(yi)(yi)層(ceng)(ceng)(ceng)厚度(du)150mm水泥沙(sha)漿找平。最上層(ceng)(ceng)(ceng)套(tao)管(guan)(guan)距地面應大于(yu)或(huo)等于(yu)700mm,套(tao)管(guan)(guan)兩(liang)邊留寬200~300mm.并(bing)在套(tao)管(guan)(guan)安(an)裝時(shi)注意套(tao)管(guan)(guan)一(yi)(yi)般長為(wei)6m,原(yuan)則上管(guan)(guan)枕平均(jun)間距為(wei)1.5m左右,管(guan)(guan)枕離管(guan)(guan)端不大于(yu)0.6m.套(tao)管(guan)(guan)根據(ju)施(shi)工圖分(fen)層(ceng)(ceng)(ceng)安(an)裝。

  可(ke)(ke)再(zai)套(tao)管(guan)(guan)(guan)(guan)(guan)兩端配合施工(gong)(gong),在(zai)(zai)套(tao)管(guan)(guan)(guan)(guan)(guan)擴(kuo)口部裝(zhuang)(zhuang)上(shang)套(tao)管(guan)(guan)(guan)(guan)(guan)生產(chan)廠家(jia)配套(tao)提供(gong)的密封圈,在(zai)(zai)密封圈內壁(bi)與(yu)套(tao)管(guan)(guan)(guan)(guan)(guan)插入端外壁(bi)涂上(shang)肥皂水或水性潤(run)滑(hua)劑,禁(jin)止使(shi)用(yong)潤(run)滑(hua)油(you)進(jin)行潤(run)滑(hua)!兩人協力(li)使(shi)用(yong)插管(guan)(guan)(guan)(guan)(guan)機將(jiang)管(guan)(guan)(guan)(guan)(guan)插入至(zhi)限位線,也(ye)可(ke)(ke)用(yong)大(da)木板墊于套(tao)管(guan)(guan)(guan)(guan)(guan)另(ling)一端,用(yong)大(da)錘均勻敲擊,將(jiang)管(guan)(guan)(guan)(guan)(guan)插入,因(yin)為PVC-C套(tao)管(guan)(guan)(guan)(guan)(guan)有較(jiao)大(da)脆性,不可(ke)(ke)野蠻施工(gong)(gong),大(da)力(li)沖擊,否則套(tao)管(guan)(guan)(guan)(guan)(guan)可(ke)(ke)能斷(duan)裂、開拆、缺口。建議安(an)裝(zhuang)(zhuang)作業工(gong)(gong)人在(zai)(zai)施工(gong)(gong)前(qian)應尋求(qiu)適當(dang)培訓。

  回(hui)(hui)(hui)填(tian)(tian)(tian)物(wu)應以(yi)散熱性(xing)能(neng)好,固態穩定性(xing)好為原則。建議(yi)采(cai)用(yong)直徑不(bu)大于5mm的(de)清潔(jie)河砂(sha)回(hui)(hui)(hui)填(tian)(tian)(tian),每鋪一(yi)層(ceng)(ceng)套管,用(yong)人工分層(ceng)(ceng)夯(hang)實(shi),不(bu)能(neng)多層(ceng)(ceng)安裝后一(yi)次回(hui)(hui)(hui)填(tian)(tian)(tian)。禁止采(cai)用(yong)生活垃圾、有/機物(wu)等物(wu)回(hui)(hui)(hui)填(tian)(tian)(tian),回(hui)(hui)(hui)填(tian)(tian)(tian)物(wu)應超過頂層(ceng)(ceng)套管200~300mm后方(fang)可(ke)采(cai)用(yong)機械夯(hang)實(shi)。
