頂(ding)管(guan)(guan)(guan)施(shi)工(gong)(gong)(gong)就(jiu)是非開(kai)挖(wa)施(shi)工(gong)(gong)(gong)方(fang)法，是一(yi)種不開(kai)挖(wa)或者少(shao)開(kai)挖(wa)的(de)(de)管(guan)(guan)(guan)道(dao)埋設施(shi)工(gong)(gong)(gong)技術。頂(ding)管(guan)(guan)(guan)法施(shi)工(gong)(gong)(gong)就(jiu)是在(zai)工(gong)(gong)(gong)作坑(keng)內借助(zhu)于(yu)頂(ding)進(jin)設備(bei)產生的(de)(de)頂(ding)力，克服管(guan)(guan)(guan)道(dao)與周(zhou)圍(wei)土壤(rang)的(de)(de)摩擦力，將(jiang)管(guan)(guan)(guan)道(dao)按設計的(de)(de)坡度頂(ding)入土中，并(bing)將(jiang)土方(fang)運(yun)走。一(yi)節管(guan)(guan)(guan)子完成頂(ding)入土層之(zhi)后，再下第二節管(guan)(guan)(guan)子繼(ji)續頂(ding)進(jin)。其原理是借助(zhu)于(yu)主(zhu)頂(ding)油缸及管(guan)(guan)(guan)道(dao)間、中繼(ji)間等推力，把工(gong)(gong)(gong)具管(guan)(guan)(guan)或掘(jue)進(jin)機從工(gong)(gong)(gong)作坑(keng)內穿過(guo)土層一(yi)直推進(jin)到接收坑(keng)內吊起。管(guan)(guan)(guan)道(dao)緊(jin)隨(sui)工(gong)(gong)(gong)具管(guan)(guan)(guan)或掘(jue)進(jin)機后，埋設在(zai)兩坑(keng)之(zhi)間。
