由于當時(shi)的(de)(de)頂管(guan)(guan)掘(jue)進機(ji)(ji)的(de)(de)設(she)計(ji)還停留在(zai)比較(jiao)原始的(de)(de)階段，既沒(mei)有完整的(de)(de)設(she)計(ji)施工(gong)理論和工(gong)藝(yi)作指導，也(ye)不考慮具體的(de)(de)地層條件，所(suo)以當時(shi)的(de)(de)頂管(guan)(guan)掘(jue)進機(ji)(ji)還不夠(gou)完善(shan)。土(tu)(tu)壓式頂管(guan)(guan)機(ji)(ji)當時(shi)分為上部出(chu)土(tu)(tu)和下部出(chu)土(tu)(tu)兩種，但都沒(mei)有引(yin)入(ru)土(tu)(tu)壓力的(de)(de)概念。其中，也(ye)搞了(le)一些(xie)水沖(chong)頂管(guan)(guan)的(de)(de)試驗(yan)。1967年(nian)前后(hou)(hou)，上海已(yi)研制(zhi)成(cheng)功人不必進入(ru)管(guan)(guan)子的(de)(de)小(xiao)口徑(jing)遙控土(tu)(tu)壓式機(ji)(ji)械頂管(guan)(guan)機(ji)(ji)，口徑(jing)有700mm-1050mm多種規格。在(zai)他們的(de)(de)施工(gong)實(shi)例中，有穿過鐵路(lu)、公路(lu)的(de)(de)，也(ye)有在(zai)一般道路(lu)下施工(gong)的(de)(de)。這(zhe)些(xie)掘(jue)進機(ji)(ji)，全部是全斷面切削，采用皮帶輸送機(ji)(ji)出(chu)土(tu)(tu)。同時(shi)，已(yi)采用了(le)液壓糾偏(pian)(pian)系統，并且(qie)糾偏(pian)(pian)油缸(gang)伸出(chu)的(de)(de)長度已(yi)用數字顯示。1978年(nian)前后(hou)(hou)，上海又研制(zhi)成(cheng)功適用于軟(ruan)粘土(tu)(tu)和淤泥質粘土(tu)(tu)的(de)(de)擠壓法頂管(guan)(guan)，這(zhe)種方法要求(qiu)的(de)(de)覆土(tu)(tu)厚度較(jiao)大的(de)(de)(大于2倍(bei)的(de)(de)管(guan)(guan)外徑(jing))，但施工(gong)效率(lv)比普通手掘(jue)式頂管(guan)(guan)提高1倍(bei)以上。

長期以來，城市建設(she)過(guo)程中(zhong)，城市道(dao)(dao)路被頻繁開挖(wa)嚴(yan)重影響(xiang)了(le)人(ren)民的(de)生活(huo)。一(yi)項非開挖(wa)施(shi)(shi)工(gong)(gong)(gong)(gong)技(ji)術——頂管(guan)(guan)(guan)施(shi)(shi)工(gong)(gong)(gong)(gong)技(ji)術，不需開挖(wa)地面，并且能夠穿越公(gong)路、鐵路、河道(dao)(dao)、湖泊、建筑物、以及各(ge)種地下管(guan)(guan)(guan)線等(deng)，解(jie)決(jue)了(le)市政(zheng)施(shi)(shi)工(gong)(gong)(gong)(gong)難題，而且，頂管(guan)(guan)(guan)施(shi)(shi)工(gong)(gong)(gong)(gong)隨(sui)著(zhu)城市建設(she)的(de)發展已(yi)越來越普及，已(yi)運用(yong)到給排水、煤(mei)氣(qi)、電力、通信等(deng)管(guan)(guan)(guan)道(dao)(dao)的(de)施(shi)(shi)工(gong)(gong)(gong)(gong)。頂管(guan)(guan)(guan)法施(shi)(shi)工(gong)(gong)(gong)(gong)就是在(zai)工(gong)(gong)(gong)(gong)作(zuo)坑(keng)內(nei)借助于頂進(jin)(jin)設(she)備產生的(de)頂力，克服管(guan)(guan)(guan)道(dao)(dao)與周圍土壤的(de)摩擦力，將管(guan)(guan)(guan)道(dao)(dao)按設(she)計的(de)坡度頂入(ru)土中(zhong)，并將土方運走。一(yi)節管(guan)(guan)(guan)子(zi)完成頂入(ru)土層(ceng)之后，再下第(di)二節管(guan)(guan)(guan)子(zi)繼(ji)續頂進(jin)(jin)。其原理是借助于主頂油缸及管(guan)(guan)(guan)道(dao)(dao)間、中(zhong)繼(ji)間等(deng)推力，把工(gong)(gong)(gong)(gong)具管(guan)(guan)(guan)或掘(jue)進(jin)(jin)機從工(gong)(gong)(gong)(gong)作(zuo)坑(keng)內(nei)穿過(guo)土層(ceng)一(yi)直推進(jin)(jin)到接收坑(keng)內(nei)吊(diao)起。管(guan)(guan)(guan)道(dao)(dao)緊隨(sui)工(gong)(gong)(gong)(gong)具管(guan)(guan)(guan)或掘(jue)進(jin)(jin)機后，埋設(she)在(zai)兩坑(keng)之間。工(gong)(gong)(gong)(gong)作(zuo)井和接收井上(shang)部(bu)采用(yong)人(ren)機配合開完，下部(bu)采取人(ren)工(gong)(gong)(gong)(gong)開挖(wa)作(zuo)法作(zuo)業(ye)。
