頂(ding)管(guan)施(shi)工(gong)(gong)(gong)(gong)就是(shi)非開(kai)挖(wa)(wa)施(shi)工(gong)(gong)(gong)(gong)方法，是(shi)一種不(bu)開(kai)挖(wa)(wa)或者(zhe)少(shao)開(kai)挖(wa)(wa)的(de)管(guan)道(dao)埋(mai)設施(shi)工(gong)(gong)(gong)(gong)技術。頂(ding)管(guan)法施(shi)工(gong)(gong)(gong)(gong)就是(shi)在工(gong)(gong)(gong)(gong)作坑(keng)(keng)內(nei)借助于頂(ding)進(jin)設備產生的(de)頂(ding)力，克(ke)服管(guan)道(dao)與周圍土(tu)(tu)壤的(de)摩擦力，將管(guan)道(dao)按設計(ji)的(de)坡(po)度頂(ding)入土(tu)(tu)中(zhong)，并將土(tu)(tu)方運(yun)走。一節管(guan)子(zi)完(wan)成頂(ding)入土(tu)(tu)層之后，再(zai)下第二(er)節管(guan)子(zi)繼續(xu)頂(ding)進(jin)。其原理是(shi)借助于主頂(ding)油(you)缸及管(guan)道(dao)間、中(zhong)繼間等推力，把工(gong)(gong)(gong)(gong)具管(guan)或掘進(jin)機從工(gong)(gong)(gong)(gong)作坑(keng)(keng)內(nei)穿過土(tu)(tu)層一直推進(jin)到(dao)接(jie)收坑(keng)(keng)內(nei)吊起。管(guan)道(dao)緊隨工(gong)(gong)(gong)(gong)具管(guan)或掘進(jin)機后，埋(mai)設在兩坑(keng)(keng)之間。
