頂(ding)(ding)(ding)管(guan)(guan)施(shi)(shi)工就(jiu)是非開挖(wa)施(shi)(shi)工方法，是一(yi)種(zhong)不(bu)開挖(wa)或者少(shao)開挖(wa)的管(guan)(guan)道埋設(she)(she)(she)施(shi)(shi)工技術。頂(ding)(ding)(ding)管(guan)(guan)法施(shi)(shi)工就(jiu)是在工作坑內借助于頂(ding)(ding)(ding)進(jin)(jin)設(she)(she)(she)備產生的頂(ding)(ding)(ding)力，克服管(guan)(guan)道與周圍土(tu)(tu)(tu)壤的摩擦力，將管(guan)(guan)道按設(she)(she)(she)計的坡度(du)頂(ding)(ding)(ding)入土(tu)(tu)(tu)中(zhong)，并將土(tu)(tu)(tu)方運(yun)走。一(yi)節(jie)管(guan)(guan)子完成頂(ding)(ding)(ding)入土(tu)(tu)(tu)層之后，再(zai)下第二(er)節(jie)管(guan)(guan)子繼續(xu)頂(ding)(ding)(ding)進(jin)(jin)。其原理是借助于主頂(ding)(ding)(ding)油缸(gang)及(ji)管(guan)(guan)道間(jian)(jian)、中(zhong)繼間(jian)(jian)等推(tui)(tui)力，把工具管(guan)(guan)或掘進(jin)(jin)機(ji)從(cong)工作坑內穿過土(tu)(tu)(tu)層一(yi)直推(tui)(tui)進(jin)(jin)到接收(shou)坑內吊起(qi)。管(guan)(guan)道緊隨工具管(guan)(guan)或掘進(jin)(jin)機(ji)后，埋設(she)(she)(she)在兩(liang)坑之間(jian)(jian)。
