頂(ding)管(guan)(guan)施工(gong)就是非開挖施工(gong)方(fang)法，是一種(zhong)不(bu)開挖或(huo)者少(shao)開挖的(de)管(guan)(guan)道(dao)埋設(she)(she)施工(gong)技術。頂(ding)管(guan)(guan)法施工(gong)就是在工(gong)作坑(keng)(keng)內(nei)借助于(yu)(yu)頂(ding)進(jin)(jin)設(she)(she)備(bei)產生的(de)頂(ding)力，克服管(guan)(guan)道(dao)與(yu)周圍土(tu)壤(rang)的(de)摩擦力，將(jiang)管(guan)(guan)道(dao)按設(she)(she)計的(de)坡度頂(ding)入土(tu)中，并將(jiang)土(tu)方(fang)運(yun)走(zou)。一節管(guan)(guan)子完成頂(ding)入土(tu)層之后(hou)，再下第二節管(guan)(guan)子繼續(xu)頂(ding)進(jin)(jin)。其原理(li)是借助于(yu)(yu)主頂(ding)油(you)缸(gang)及(ji)管(guan)(guan)道(dao)間(jian)、中繼間(jian)等推(tui)力，把(ba)工(gong)具管(guan)(guan)或(huo)掘進(jin)(jin)機從工(gong)作坑(keng)(keng)內(nei)穿過土(tu)層一直(zhi)推(tui)進(jin)(jin)到接收坑(keng)(keng)內(nei)吊(diao)起。管(guan)(guan)道(dao)緊隨工(gong)具管(guan)(guan)或(huo)掘進(jin)(jin)機后(hou)，埋設(she)(she)在兩坑(keng)(keng)之間(jian)。
