頂(ding)(ding)管(guan)(guan)(guan)施工(gong)(gong)就是(shi)非開挖施工(gong)(gong)方法，是(shi)一(yi)種不開挖或者(zhe)少開挖的(de)管(guan)(guan)(guan)道(dao)埋設施工(gong)(gong)技術。頂(ding)(ding)管(guan)(guan)(guan)法施工(gong)(gong)就是(shi)在工(gong)(gong)作(zuo)坑內借助(zhu)于頂(ding)(ding)進設備產生(sheng)的(de)頂(ding)(ding)力，克服管(guan)(guan)(guan)道(dao)與周圍土(tu)壤的(de)摩擦力，將管(guan)(guan)(guan)道(dao)按(an)設計的(de)坡度頂(ding)(ding)入(ru)土(tu)中，并將土(tu)方運走。一(yi)節(jie)管(guan)(guan)(guan)子完(wan)成頂(ding)(ding)入(ru)土(tu)層之后(hou)，再(zai)下第二節(jie)管(guan)(guan)(guan)子繼(ji)續頂(ding)(ding)進。其原理是(shi)借助(zhu)于主頂(ding)(ding)油缸(gang)及(ji)管(guan)(guan)(guan)道(dao)間、中繼(ji)間等(deng)推(tui)力，把工(gong)(gong)具(ju)管(guan)(guan)(guan)或掘(jue)進機從(cong)工(gong)(gong)作(zuo)坑內穿過土(tu)層一(yi)直推(tui)進到接收(shou)坑內吊(diao)起。管(guan)(guan)(guan)道(dao)緊隨工(gong)(gong)具(ju)管(guan)(guan)(guan)或掘(jue)進機后(hou)，埋設在兩坑之間。
