成套頂(ding)管(guan)(guan)機械(xie)進(jin)入(ru)現(xian)場后(hou)，將(jiang)控制柜(ju)放在頂(ding)管(guan)(guan)井(jing)一(yi)側，略微(wei)離井(jing)邊(bian)一(yi)點，方便操作人(ren)員看到(dao)井(jing)下頂(ding)進(jin)狀況。先澆(jiao)筑好背(bei)靠墻，裝置導軌，千斤頂(ding)，打鑿好洞(dong)口，吊(diao)管(guan)(guan)下井(jing)，裝置好進(jin)水(shui)管(guan)(guan)和(he)出泥管(guan)(guan)。頂(ding)管(guan)(guan)施(shi)工(gong)是一(yi)種在不(bu)開(kai)挖(wa)或許(xu)少開(kai)挖(wa)路(lu)面(mian)(mian)的(de)狀況下，管(guan)(guan)道(dao)非開(kai)挖(wa)施(shi)工(gong)多少錢(qian)，埋設(she)管(guan)(guan)道(dao)的(de)施(shi)工(gong)技術，可解(jie)決(jue)管(guan)(guan)道(dao)埋設(she)施(shi)工(gong)對城(cheng)市建筑物的(de)毀壞和(he)形成交通(tong)(tong)堵塞的(de)難(nan)題，在波動土(tu)層和(he)環(huan)境保(bao)護方具有(you)優勢。頂(ding)管(guan)(guan)施(shi)工(gong)降(jiang)低交通(tong)(tong)壓力。對城(cheng)市交通(tong)(tong)攪(jiao)擾小(xiao)，施(shi)工(gong)面(mian)(mian)由線縮(suo)成點，占地面(mian)(mian)積小(xiao)，且不(bu)會招致(zhi)路(lu)面(mian)(mian)沉降(jiang)以致(zhi)發生(sheng)裂紋，防止了路(lu)面(mian)(mian)重修。

它能穿(chuan)越公(gong)路(lu)、鐵路(lu)、橋梁、高山、河流(liu)、海峽和(he)地(di)(di)面任何建筑物(wu)。采用(yong)(yong)該技(ji)術施工(gong)，能節(jie)約一大筆拆費(fei)用(yong)(yong)、減(jian)少(shao)對環境污染和(he)道路(lu)的(de)堵塞，具(ju)有顯著的(de)經濟效益和(he)社(she)會效益。通過工(gong)作井(jing)把要頂(ding)進的(de)管(guan)(guan)子頂(ding)入接收井(jing)內，一個工(gong)作井(jing)內的(de)管(guan)(guan)子可在地(di)(di)下穿(chuan)行1500米以上，并且還能曲線穿(chuan)行，以繞開(kai)一些(xie)地(di)(di)下管(guan)(guan)線或障礙物(wu)。頂(ding)管(guan)(guan)施工(gong)技(ji)術是(shi)一種管(guan)(guan)道鋪裝(zhuang)技(ji)術，無(wu)需(xu)開(kai)挖(wa)地(di)(di)面，有具(ju)大推力(li)的(de)液壓(ya)千斤頂(ding)可用(yong)(yong)在有遙控裝(zhuang)置的(de)頂(ding)管(guan)(guan)掘進機(ji)的(de)后方，使(shi)掘進機(ji)及緊隨(sui)其(qi)后的(de)管(guan)(guan)道穿(chuan)越土層，達到預先設計的(de)位置上，這就稱為頂(ding)管(guan)(guan)工(gong)程。
