頂(ding)(ding)(ding)(ding)管(guan)(guan)(guan)(guan)(guan)(guan)施工就是(shi)非(fei)開(kai)挖(wa)施工方(fang)法，是(shi)一(yi)種不開(kai)挖(wa)或(huo)者少開(kai)挖(wa)的(de)管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)埋(mai)設(she)施工技術(shu)。頂(ding)(ding)(ding)(ding)管(guan)(guan)(guan)(guan)(guan)(guan)法施工就是(shi)在工作坑(keng)內(nei)借助于頂(ding)(ding)(ding)(ding)進設(she)備(bei)產生的(de)頂(ding)(ding)(ding)(ding)力，克(ke)服管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)與周圍(wei)土(tu)壤的(de)摩擦力，將(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)按設(she)計的(de)坡度(du)頂(ding)(ding)(ding)(ding)入土(tu)中，并將(jiang)土(tu)方(fang)運走。一(yi)節(jie)管(guan)(guan)(guan)(guan)(guan)(guan)子(zi)完(wan)成頂(ding)(ding)(ding)(ding)入土(tu)層(ceng)之后(hou)，再(zai)下第二節(jie)管(guan)(guan)(guan)(guan)(guan)(guan)子(zi)繼續頂(ding)(ding)(ding)(ding)進。其原理是(shi)借助于主頂(ding)(ding)(ding)(ding)油缸及管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)間(jian)、中繼間(jian)等(deng)推力，把工具(ju)管(guan)(guan)(guan)(guan)(guan)(guan)或(huo)掘進機(ji)從(cong)工作坑(keng)內(nei)穿過土(tu)層(ceng)一(yi)直推進到接收坑(keng)內(nei)吊(diao)起(qi)。管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)緊(jin)隨工具(ju)管(guan)(guan)(guan)(guan)(guan)(guan)或(huo)掘進機(ji)后(hou)，埋(mai)設(she)在兩坑(keng)之間(jian)。
