頂(ding)(ding)(ding)管(guan)施工(gong)(gong)就(jiu)是非開(kai)挖施工(gong)(gong)方(fang)法，是一種不(bu)開(kai)挖或者(zhe)少開(kai)挖的管(guan)道(dao)埋(mai)(mai)設(she)施工(gong)(gong)技術。頂(ding)(ding)(ding)管(guan)法施工(gong)(gong)就(jiu)是在工(gong)(gong)作坑(keng)內(nei)(nei)借(jie)(jie)助(zhu)于頂(ding)(ding)(ding)進(jin)(jin)設(she)備產生(sheng)的頂(ding)(ding)(ding)力(li)，克服管(guan)道(dao)與(yu)周(zhou)圍土(tu)(tu)壤的摩(mo)擦力(li)，將管(guan)道(dao)按設(she)計的坡度頂(ding)(ding)(ding)入(ru)土(tu)(tu)中(zhong)，并將土(tu)(tu)方(fang)運(yun)走。一節(jie)管(guan)子(zi)(zi)完成頂(ding)(ding)(ding)入(ru)土(tu)(tu)層之后，再下第二節(jie)管(guan)子(zi)(zi)繼續頂(ding)(ding)(ding)進(jin)(jin)。其原(yuan)理(li)是借(jie)(jie)助(zhu)于主(zhu)頂(ding)(ding)(ding)油缸(gang)及管(guan)道(dao)間、中(zhong)繼間等推力(li)，把工(gong)(gong)具(ju)管(guan)或掘進(jin)(jin)機從工(gong)(gong)作坑(keng)內(nei)(nei)穿過(guo)土(tu)(tu)層一直推進(jin)(jin)到接收坑(keng)內(nei)(nei)吊(diao)起。管(guan)道(dao)緊(jin)隨(sui)工(gong)(gong)具(ju)管(guan)或掘進(jin)(jin)機后，埋(mai)(mai)設(she)在兩坑(keng)之間。
