頂(ding)(ding)管(guan)(guan)(guan)(guan)施工(gong)(gong)就(jiu)是非開挖施工(gong)(gong)方法，是一種不開挖或(huo)(huo)者少開挖的管(guan)(guan)(guan)(guan)道埋(mai)設(she)(she)施工(gong)(gong)技術。頂(ding)(ding)管(guan)(guan)(guan)(guan)法施工(gong)(gong)就(jiu)是在(zai)工(gong)(gong)作坑(keng)內(nei)借(jie)助(zhu)于頂(ding)(ding)進(jin)設(she)(she)備產(chan)生的頂(ding)(ding)力(li)，克服管(guan)(guan)(guan)(guan)道與(yu)周圍(wei)土(tu)壤的摩擦力(li)，將管(guan)(guan)(guan)(guan)道按設(she)(she)計的坡度頂(ding)(ding)入(ru)土(tu)中(zhong)，并將土(tu)方運走。一節(jie)管(guan)(guan)(guan)(guan)子(zi)完(wan)成頂(ding)(ding)入(ru)土(tu)層之后(hou)，再(zai)下第二節(jie)管(guan)(guan)(guan)(guan)子(zi)繼續頂(ding)(ding)進(jin)。其(qi)原理是借(jie)助(zhu)于主頂(ding)(ding)油缸及管(guan)(guan)(guan)(guan)道間(jian)(jian)、中(zhong)繼間(jian)(jian)等推(tui)(tui)力(li)，把工(gong)(gong)具管(guan)(guan)(guan)(guan)或(huo)(huo)掘進(jin)機(ji)(ji)從工(gong)(gong)作坑(keng)內(nei)穿過土(tu)層一直推(tui)(tui)進(jin)到(dao)接收坑(keng)內(nei)吊起。管(guan)(guan)(guan)(guan)道緊隨工(gong)(gong)具管(guan)(guan)(guan)(guan)或(huo)(huo)掘進(jin)機(ji)(ji)后(hou)，埋(mai)設(she)(she)在(zai)兩(liang)坑(keng)之間(jian)(jian)。
