水(shui)(shui)鉆頂(ding)(ding)管(guan)(guan)(guan)機(ji)(ji)前(qian)方配有合金鉆頭，即(ji)使是巖石，樓板，非金屬堅固物體(ti)(ti)(ti)，錐(zhui)體(ti)(ti)(ti)式泥水(shui)(shui)平衡(heng)頂(ding)(ding)管(guan)(guan)(guan)機(ji)(ji)，頂(ding)(ding)管(guan)(guan)(guan)機(ji)(ji)也能夠(gou)順利穿過(guo)，遇(yu)到堅固物體(ti)(ti)(ti)時(shi)(shi)，不(bu)跑(pao)偏(pian)不(bu)打滑，但直接影響進(jin)程速度，請使用時(shi)(shi)分(fen)辨(bian)好(hao)地(di)下(xia)是否(fou)有其(qi)他(ta)物體(ti)(ti)(ti)。水(shui)(shui)鉆頂(ding)(ding)管(guan)(guan)(guan)機(ji)(ji)在一(yi)般情(qing)況下(xia)可采(cai)用直頂(ding)(ding)式頂(ding)(ding)管(guan)(guan)(guan)，注：（在口徑小長(chang)(chang)度短的(de)情(qing)況下(xia)）一(yi)般口徑小于30—50MM長(chang)(chang)度不(bu)大于49M的(de)情(qing)況下(xia)可采(cai)用直接頂(ding)(ding)入，不(bu)用注水(shui)(shui)，大大節省了工作時(shi)(shi)間。

頂管施工注意事項

一、由于沙石的(de)比重比較大，要(yao)(yao)求泥(ni)漿(jiang)濃(nong)度(du)要(yao)(yao)高（必(bi)要(yao)(yao)時(shi)要(yao)(yao)造(zao)漿(jiang)：攪拌(ban)膨潤(run)土注入泥(ni)漿(jiang)池），管內水(shui)流的(de)速度(du)要(yao)(yao)快，防止卵石沉(chen)積(ji)堵(du)塞管道。

二、在布置(zhi)排水(shui)管線時(shi)應減少管線彎頭的數(shu)量，每(mei)增(zeng)加(jia)一個(ge)90度(du)彎頭，錐(zhui)體式(shi)泥水(shui)平衡頂(ding)管機批發，管內流速降低10%~20%，錐(zhui)體式(shi)泥水(shui)平衡頂(ding)管機規格，使(shi)用(yong)彎頭也要用(yong)大弧度(du)90度(du)彎頭不(bu)要用(yong)小弧度(du)90度(du)彎頭。
