頂(ding)(ding)管(guan)(guan)施工(gong)(gong)就(jiu)是(shi)非開(kai)挖(wa)施工(gong)(gong)方(fang)法(fa)，是(shi)一(yi)種不(bu)開(kai)挖(wa)或(huo)者少開(kai)挖(wa)的(de)管(guan)(guan)道(dao)(dao)埋設施工(gong)(gong)技術。頂(ding)(ding)管(guan)(guan)法(fa)施工(gong)(gong)就(jiu)是(shi)在工(gong)(gong)作坑內借助(zhu)(zhu)于頂(ding)(ding)進(jin)設備產生的(de)頂(ding)(ding)力，克服(fu)管(guan)(guan)道(dao)(dao)與周圍土壤的(de)摩擦力，將管(guan)(guan)道(dao)(dao)按設計的(de)坡度頂(ding)(ding)入土中，并(bing)將土方(fang)運走。一(yi)節管(guan)(guan)子完成頂(ding)(ding)入土層(ceng)之后(hou)，再下第(di)二節管(guan)(guan)子繼(ji)續頂(ding)(ding)進(jin)。其原理是(shi)借助(zhu)(zhu)于主頂(ding)(ding)油缸(gang)及管(guan)(guan)道(dao)(dao)間、中繼(ji)間等(deng)推力，把工(gong)(gong)具管(guan)(guan)或(huo)掘進(jin)機(ji)(ji)從工(gong)(gong)作坑內穿過土層(ceng)一(yi)直推進(jin)到接收坑內吊起。管(guan)(guan)道(dao)(dao)緊隨(sui)工(gong)(gong)具管(guan)(guan)或(huo)掘進(jin)機(ji)(ji)后(hou)，埋設在兩(liang)坑之間。
