頂(ding)(ding)管(guan)(guan)(guan)施工(gong)(gong)(gong)就(jiu)是(shi)非開(kai)挖(wa)施工(gong)(gong)(gong)方(fang)法，是(shi)一(yi)種不開(kai)挖(wa)或者少開(kai)挖(wa)的(de)管(guan)(guan)(guan)道埋設(she)施工(gong)(gong)(gong)技術。頂(ding)(ding)管(guan)(guan)(guan)法施工(gong)(gong)(gong)就(jiu)是(shi)在工(gong)(gong)(gong)作坑(keng)(keng)(keng)內借助(zhu)(zhu)于(yu)頂(ding)(ding)進設(she)備產生的(de)頂(ding)(ding)力(li)，克(ke)服管(guan)(guan)(guan)道與周圍(wei)土(tu)(tu)壤(rang)的(de)摩擦力(li)，將管(guan)(guan)(guan)道按設(she)計的(de)坡度頂(ding)(ding)入土(tu)(tu)中，并將土(tu)(tu)方(fang)運走。一(yi)節(jie)管(guan)(guan)(guan)子完成頂(ding)(ding)入土(tu)(tu)層(ceng)之后，再下第二節(jie)管(guan)(guan)(guan)子繼(ji)續頂(ding)(ding)進。其原理(li)是(shi)借助(zhu)(zhu)于(yu)主頂(ding)(ding)油缸及管(guan)(guan)(guan)道間、中繼(ji)間等推(tui)力(li)，把工(gong)(gong)(gong)具管(guan)(guan)(guan)或掘進機從工(gong)(gong)(gong)作坑(keng)(keng)(keng)內穿(chuan)過土(tu)(tu)層(ceng)一(yi)直推(tui)進到接(jie)收坑(keng)(keng)(keng)內吊起。管(guan)(guan)(guan)道緊隨工(gong)(gong)(gong)具管(guan)(guan)(guan)或掘進機后，埋設(she)在兩坑(keng)(keng)(keng)之間。
