頂(ding)管技(ji)術(shu)是(shi)一項用于市政施(shi)工(gong)(gong)的非開挖掘進式管道鋪(pu)設(she)施(shi)工(gong)(gong)技(ji)術(shu)。優點(dian)在于不影響周圍(wei)環(huan)境(jing)或(huo)者影響較(jiao)(jiao)小(xiao)，施(shi)工(gong)(gong)場(chang)地小(xiao)，噪(zao)音小(xiao)。而且能夠深(shen)入地下(xia)作業，這是(shi)開挖埋管無法比擬的優點(dian)。但是(shi)頂(ding)管技(ji)術(shu)也有缺(que)點(dian)，施(shi)工(gong)(gong)時間較(jiao)(jiao)長，工(gong)(gong)程造價高等。

頂(ding)管(guan)(guan)施工(gong)(gong)(gong)是繼盾(dun)構施工(gong)(gong)(gong)之后而發(fa)展起來(lai)的一種地(di)(di)(di)下(xia)管(guan)(guan)道(dao)(dao)(dao)(dao)施工(gong)(gong)(gong)方(fang)法(fa)，頂(ding)管(guan)(guan)非開挖工(gong)(gong)(gong)程施工(gong)(gong)(gong)公司(si)不需要開挖面層，并(bing)且能夠穿(chuan)越公路、鐵道(dao)(dao)(dao)(dao)、河川(chuan)、地(di)(di)(di)面建筑(zhu)物、地(di)(di)(di)下(xia)構筑(zhu)物以(yi)及各種地(di)(di)(di)下(xia)管(guan)(guan)線(xian)等。頂(ding)管(guan)(guan)施工(gong)(gong)(gong)借助于主(zhu)頂(ding)油(you)缸及管(guan)(guan)道(dao)(dao)(dao)(dao)間(jian)中(zhong)繼間(jian)等的推(tui)力，把工(gong)(gong)(gong)具(ju)管(guan)(guan)或掘進機(ji)從工(gong)(gong)(gong)作井內穿(chuan)過土層一直推(tui)到接收井內吊起。與此同時，也就(jiu)把緊隨(sui)工(gong)(gong)(gong)具(ju)管(guan)(guan)或掘進機(ji)后的管(guan)(guan)道(dao)(dao)(dao)(dao)埋設(she)在兩井之間(jian)，以(yi)期實現非開挖敷(fu)設(she)地(di)(di)(di)下(xia)管(guan)(guan)道(dao)(dao)(dao)(dao)的施工(gong)(gong)(gong)方(fang)法(fa)。
