鋼(gang)筋混凝土頂(ding)(ding)管(guan)接(jie)頭形式多樣(yang)，無論采用哪(na)一種接(jie)頭方(fang)式，均可到(dao)達迅(xun)速(su)銜接(jie)的效果，普通幾分鐘即可完成。此外(wai)，還無需停止(zhi)防腐(fu)操作(zuo)(zuo)(zuo)，可大(da)大(da)提(ti)升工(gong)作(zuo)(zuo)(zuo)效率。頂(ding)(ding)進計算(suan)頂(ding)(ding)進計算(suan)其一包括(kuo)準確(que)計算(suan)頂(ding)(ding)進推力，根(gen)據計算(suan)結果選(xuan)定(ding)相應的油缸類型和確(que)定(ding)中繼間的分布;其二(er)是工(gong)作(zuo)(zuo)(zuo)井(jing)設計，根(gen)據計算(suan)得到(dao)的 大(da)頂(ding)(ding)力，提(ti)出(chu)工(gong)作(zuo)(zuo)(zuo)井(jing)的加固方(fang)案。成套(tao)頂(ding)(ding)管(guan)機(ji)械進入(ru)現(xian)場后，將控(kong)制柜(ju)放在(zai)頂(ding)(ding)管(guan)井(jing)一側，略微離井(jing)邊一點，方(fang)便(bian)操作(zuo)(zuo)(zuo)人(ren)員看到(dao)井(jing)下頂(ding)(ding)進狀況。先澆筑(zhu)好(hao)背靠墻，裝置(zhi)(zhi)導軌，千斤(jin)頂(ding)(ding)，打鑿好(hao)洞口(kou)，吊管(guan)下井(jing)，裝置(zhi)(zhi)好(hao)進水管(guan)和出(chu)泥管(guan)。

頂(ding)管(guan)施(shi)(shi)工(gong)(gong)就(jiu)是(shi)(shi)非開(kai)挖(wa)(wa)施(shi)(shi)工(gong)(gong)方(fang)法，是(shi)(shi)一種不(bu)開(kai)挖(wa)(wa)或者(zhe)少開(kai)挖(wa)(wa)的(de)管(guan)道(dao)埋設施(shi)(shi)工(gong)(gong)技術。頂(ding)管(guan)法施(shi)(shi)工(gong)(gong)就(jiu)是(shi)(shi)在(zai)工(gong)(gong)作坑內借助于頂(ding)進設備產生的(de)頂(ding)力，克服管(guan)道(dao)與周圍土(tu)壤(rang)的(de)摩(mo)擦力，將(jiang)管(guan)道(dao)按設計的(de)坡度頂(ding)入土(tu)中，并(bing)將(jiang)土(tu)方(fang)運走(zou)。地(di)下(xia)穿越(yue)是(shi)(shi)社會發展的(de)必然要(yao)求。無論是(shi)(shi)各(ge)行業部門規(gui)劃(hua)不(bu)到位，協調(diao)不(bu)好，還是(shi)(shi)基(ji)建(jian)發展需要(yao)，新的(de)地(di)下(xia)設施(shi)(shi)總在(zai)不(bu)斷增(zeng)加(jia)，這時要(yao)么開(kai)挖(wa)(wa)，要(yao)么非開(kai)挖(wa)(wa)，必然選擇其一。非開(kai)挖(wa)(wa)工(gong)(gong)程技術解(jie)決了管(guan)道(dao)埋設施(shi)(shi)工(gong)(gong)中對城市建(jian)筑(zhu)物的(de)破壞和道(dao)路交通的(de)堵塞等難(nan)題(ti)，在(zai)穩定土(tu)層和環境保護(hu)方(fang)面凸顯其優勢。
