非開挖管道拆除如何工作？

與(yu)其他非開挖技術（例如頂管和水平定向鉆(zhan)井(HDD)）一(yi)樣，非開挖管道拆除(chu)需要以入口和出(chu)口坑的(de)形式進行相(xiang)對(dui)較(jiao)小(xiao)的(de)開挖。這些坑提供了(le)一(yi)個工(gong)作區，以容(rong)納設(she)備放(fang)置并(bing)促進移除(chu)操(cao)作。

由于土壤與(yu)管道之間的(de)(de)(de)(de)摩擦（即表面摩擦）非常大，忻州(zhou)管道工程，因(yin)此拆(chai)(chai)除埋地管道是一項相當復雜的(de)(de)(de)(de)操作。可以通過考慮(lv)該(gai)摩擦值（以及其他(ta)因(yin)素）來計(ji)算在不(bu)開挖地下管道的(de)(de)(de)(de)情(qing)況下拆(chai)(chai)除地下管道所需(xu)的(de)(de)(de)(de)拉(la)力。然(ran)而(er)，摩擦提供的(de)(de)(de)(de)阻(zu)力通常會導高(gao)（甚至不(bu)切(qie)實際）的(de)(de)(de)(de)拉(la)力。

為了(le)促(cu)進 非開挖拆除工(gong)作，我(wo)們開發了(le)一種去除摩擦(ca)系(xi)統，該(gai)系(xi)統減小了(le)退役管道的直徑，雨水管道工(gong)程多少錢，從而大大降低(di)了(le)周圍土壤和管道之間的摩擦(ca)力(li)。

小編為您分(fen)享(xiang)管道(dao)工程相(xiang)關知識：

頂(ding)管施(shi)工中的頂(ding)管法能夠分為以下幾種：

(1)靜壓式頂管，即(ji)單純運(yun)用給進油(you)缸頂推(tui)及(ji)后拉(la)套管；

(2)水(shui)力沖刺(ci)靜壓式頂管(guan)，即選用高壓水(shui)力沖刺(ci)破土，油缸頂推套(tao)管(guan)，管(guan)外少量排(pai)渣(zha)；

(3)螺(luo)(luo)旋式頂管(guan)是運用(yong)(yong)螺(luo)(luo)旋鉆進行(xing)施工(gong)(gong)的一種辦法(fa)，施工(gong)(gong)時，先預備頂進坑，將(jiang)螺(luo)(luo)旋鉆機水(shui)平安裝在坑內(nei)，再運用(yong)(yong)螺(luo)(luo)旋桿傳輸鉆壓和扭矩(ju)，雨(yu)水(shui)管(guan)道工(gong)(gong)程施工(gong)(gong)，推進頂管(guan)機機頭前進。

運用鉆(zhan)(zhan)機的(de)頂進油缸向前(qian)頂進管節，機頭掘削下來(lai)的(de)土通過(guo)螺(luo)旋鉆(zhan)(zhan)桿從管中(zhong)輸送到坑(keng)內(nei)。

頂(ding)距在(zai)60m以內(nei)。其長(chang)(chang)處(chu)是施(shi)工時無轟動、噪音小(xiao)、重(zhong)量(liang)輕、操作(zuo)便利(li)、施(shi)工人員(yuan)少(shao)、基坑(keng)小(xiao)。管長(chang)(chang)2m時，選用(yong)3.6m長(chang)(chang)、1.5m寬的頂(ding)進坑(keng)即(ji)可(ke)。
