頂管(guan)(guan)(guan)施工(gong)(gong)就(jiu)是(shi)(shi)(shi)非開挖施工(gong)(gong)方(fang)法，是(shi)(shi)(shi)一(yi)(yi)種(zhong)不開挖或者少開挖的管(guan)(guan)(guan)道(dao)埋(mai)設(she)施工(gong)(gong)技術(shu)。頂管(guan)(guan)(guan)法施工(gong)(gong)就(jiu)是(shi)(shi)(shi)在(zai)工(gong)(gong)作坑內(nei)借助(zhu)于(yu)頂進設(she)備產生的頂力，克服管(guan)(guan)(guan)道(dao)與周圍土壤的摩擦(ca)力，將管(guan)(guan)(guan)道(dao)按設(she)計的坡(po)度(du)頂入土中(zhong)，并將土方(fang)運走。一(yi)(yi)節管(guan)(guan)(guan)子(zi)完成(cheng)頂入土層之后(hou)(hou)，再下(xia)第二節管(guan)(guan)(guan)子(zi)繼(ji)續頂進。其原理是(shi)(shi)(shi)借助(zhu)于(yu)主頂油缸(gang)及管(guan)(guan)(guan)道(dao)間(jian)(jian)、中(zhong)繼(ji)間(jian)(jian)等推力，把工(gong)(gong)具(ju)管(guan)(guan)(guan)或掘進機(ji)從工(gong)(gong)作坑內(nei)穿過土層一(yi)(yi)直推進到接收坑內(nei)吊起。管(guan)(guan)(guan)道(dao)緊隨(sui)工(gong)(gong)具(ju)管(guan)(guan)(guan)或掘進機(ji)后(hou)(hou)，埋(mai)設(she)在(zai)兩坑之間(jian)(jian)。
