產品詳細介紹

橋式濾(lv)(lv)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)施工(gong)(gong)方法： 1、必須(xu)嚴(yan)格使用(yong)懸吊下(xia)管(guan)(guan)(guan)(guan)(guan)(guan)工(gong)(gong)藝。 2、下(xia)管(guan)(guan)(guan)(guan)(guan)(guan)之前，先要(yao)(yao)仔細檢查(cha)一(yi)(yi)下(xia)濾(lv)(lv)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)有(you)無(wu)破損，還(huan)有(you)規格，必要(yao)(yao)時加以(yi)調(diao)整。 3、泥(ni)漿要(yao)(yao)在(zai)(zai)下(xia)管(guan)(guan)(guan)(guan)(guan)(guan)之前稀釋(shi)好，比重要(yao)(yao)小于1.2T/M3，以(yi)防(fang)堵塞(sai)濾(lv)(lv)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)縫隙，讓管(guan)(guan)(guan)(guan)(guan)(guan)內外形(xing)成較(jiao)大壓(ya)力差(cha)，從而使濾(lv)(lv)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)變形(xing)。 4、濾(lv)(lv)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)，下(xia)管(guan)(guan)(guan)(guan)(guan)(guan)操作(zuo)要(yao)(yao)平(ping)穩，若因(yin)受阻不能順利進入，就不要(yao)(yao)強(qiang)行(xing)下(xia)管(guan)(guan)(guan)(guan)(guan)(guan)。 5、洗井(jing)要(yao)(yao)采用(yong)壓(ya)縮機、潛水(shui)(shui)(shui)(shui)電(dian)泵(beng)洗井(jing)。在(zai)(zai)特殊的(de)(de)情況下(xia)采用(yong)活塞(sai)洗井(jing)時，要(yao)(yao)輕(qing)(qing)放輕(qing)(qing)拉，嚴(yan)禁猛拉猛提，以(yi)防(fang)止濾(lv)(lv)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)變形(xing)。 6、后，要(yao)(yao)根(gen)據地層(ceng)的(de)(de)實際(ji)情況，來選擇濾(lv)(lv)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)外包(bao)材料。通(tong)常以(yi)尼龍(long)過(guo)濾(lv)(lv)網(wang)為主，但必須(xu)要(yao)(yao)根(gen)據地層(ceng)砂粒的(de)(de)粒徑，來選擇尼龍(long)網(wang)的(de)(de)目數. 7.聯(lian)頂節：下(xia)套(tao)管(guan)(guan)(guan)(guan)(guan)(guan)時接(jie)在(zai)(zai)后一(yi)(yi)根(gen)套(tao)管(guan)(guan)(guan)(guan)(guan)(guan)上用(yong)來調(diao)節套(tao)管(guan)(guan)(guan)(guan)(guan)(guan)柱頂面位置，并與水(shui)(shui)(shui)(shui)泥(ni)頭(tou)連接(jie)的(de)(de)短套(tao)管(guan)(guan)(guan)(guan)(guan)(guan)。8.碰壓(ya)：在(zai)(zai)頂替水(shui)(shui)(shui)(shui)泥(ni)漿結束時，膠(jiao)塞(sai)與阻流環相撞而泵(beng)壓(ya)突增的(de)(de)現象。9’侯凝期：指(zhi)水(shui)(shui)(shui)(shui)泥(ni)石強(qiang)度滿足后續施工(gong)(gong)所要(yao)(yao)求的(de)(de)時間。10.套(tao)管(guan)(guan)(guan)(guan)(guan)(guan)程序：是指(zhi)一(yi)(yi)口(kou)井(jing)下(xia)入的(de)(de)套(tao)管(guan)(guan)(guan)(guan)(guan)(guan)層(ceng)數、類型、
