頂管(guan)施工(gong)(gong)(gong)(gong)就是(shi)(shi)非開挖(wa)施工(gong)(gong)(gong)(gong)方法(fa)，是(shi)(shi)一種不開挖(wa)或者少(shao)開挖(wa)的(de)管(guan)道(dao)埋(mai)(mai)設施工(gong)(gong)(gong)(gong)技術。頂管(guan)法(fa)施工(gong)(gong)(gong)(gong)就是(shi)(shi)在工(gong)(gong)(gong)(gong)作坑(keng)內借助于頂進(jin)設備產(chan)生的(de)頂力(li)，克服管(guan)道(dao)與周圍土(tu)(tu)壤的(de)摩擦力(li)，將管(guan)道(dao)按設計的(de)坡(po)度頂入土(tu)(tu)中，并將土(tu)(tu)方運走。一節(jie)管(guan)子完成頂入土(tu)(tu)層(ceng)之(zhi)后，再下第二節(jie)管(guan)子繼(ji)續頂進(jin)。其原理(li)是(shi)(shi)借助于主頂油(you)缸及管(guan)道(dao)間(jian)、中繼(ji)間(jian)等(deng)推(tui)力(li)，把工(gong)(gong)(gong)(gong)具管(guan)或掘(jue)(jue)進(jin)機(ji)(ji)從工(gong)(gong)(gong)(gong)作坑(keng)內穿(chuan)過土(tu)(tu)層(ceng)一直推(tui)進(jin)到接收坑(keng)內吊起。管(guan)道(dao)緊隨工(gong)(gong)(gong)(gong)具管(guan)或掘(jue)(jue)進(jin)機(ji)(ji)后，埋(mai)(mai)設在兩坑(keng)之(zhi)間(jian)。
