頂(ding)(ding)(ding)管(guan)(guan)施工(gong)(gong)就是非開挖(wa)施工(gong)(gong)方(fang)法(fa)，是一(yi)種不開挖(wa)或(huo)者少(shao)開挖(wa)的(de)管(guan)(guan)道(dao)(dao)(dao)埋設施工(gong)(gong)技術。頂(ding)(ding)(ding)管(guan)(guan)法(fa)施工(gong)(gong)就是在工(gong)(gong)作坑內借助于(yu)頂(ding)(ding)(ding)進設備產生的(de)頂(ding)(ding)(ding)力，克(ke)服管(guan)(guan)道(dao)(dao)(dao)與(yu)周(zhou)圍土(tu)壤的(de)摩擦力，將管(guan)(guan)道(dao)(dao)(dao)按設計(ji)的(de)坡度頂(ding)(ding)(ding)入土(tu)中，并將土(tu)方(fang)運走。一(yi)節管(guan)(guan)子完成(cheng)頂(ding)(ding)(ding)入土(tu)層之后，再(zai)下第二節管(guan)(guan)子繼續頂(ding)(ding)(ding)進。其原理是借助于(yu)主(zhu)頂(ding)(ding)(ding)油缸及管(guan)(guan)道(dao)(dao)(dao)間、中繼間等推力，把(ba)工(gong)(gong)具管(guan)(guan)或(huo)掘進機從工(gong)(gong)作坑內穿過(guo)土(tu)層一(yi)直推進到接(jie)收坑內吊起。管(guan)(guan)道(dao)(dao)(dao)緊隨工(gong)(gong)具管(guan)(guan)或(huo)掘進機后，埋設在兩坑之間。
