頂(ding)管(guan)施(shi)工(gong)(gong)就是(shi)非開(kai)挖(wa)(wa)(wa)施(shi)工(gong)(gong)方(fang)法，是(shi)一種不開(kai)挖(wa)(wa)(wa)或(huo)者少開(kai)挖(wa)(wa)(wa)的(de)管(guan)道埋(mai)設(she)施(shi)工(gong)(gong)技術。頂(ding)管(guan)法施(shi)工(gong)(gong)就是(shi)在工(gong)(gong)作(zuo)坑(keng)內(nei)借(jie)助(zhu)于頂(ding)進(jin)(jin)設(she)備產生(sheng)的(de)頂(ding)力(li)，克服管(guan)道與周圍(wei)土(tu)(tu)壤(rang)的(de)摩擦(ca)力(li)，將管(guan)道按設(she)計的(de)坡度頂(ding)入(ru)土(tu)(tu)中(zhong)(zhong)，并將土(tu)(tu)方(fang)運走。一節管(guan)子完成頂(ding)入(ru)土(tu)(tu)層(ceng)之(zhi)后，再下第二節管(guan)子繼(ji)續頂(ding)進(jin)(jin)。其原(yuan)理是(shi)借(jie)助(zhu)于主頂(ding)油缸及管(guan)道間(jian)、中(zhong)(zhong)繼(ji)間(jian)等推(tui)力(li)，把工(gong)(gong)具(ju)管(guan)或(huo)掘進(jin)(jin)機(ji)(ji)從工(gong)(gong)作(zuo)坑(keng)內(nei)穿過土(tu)(tu)層(ceng)一直推(tui)進(jin)(jin)到(dao)接(jie)收坑(keng)內(nei)吊起。管(guan)道緊隨工(gong)(gong)具(ju)管(guan)或(huo)掘進(jin)(jin)機(ji)(ji)后，埋(mai)設(she)在兩坑(keng)之(zhi)間(jian)。
