頂(ding)(ding)(ding)管(guan)(guan)施(shi)工設備(bei)主(zhu)要包括頂(ding)(ding)(ding)管(guan)(guan)機（因地(di)質條(tiao)件不同其刀盤不一）、中(zhong)繼間、千(qian)斤頂(ding)(ding)(ding)及(ji)泵站、龍門吊或汽車吊、操作間、導軌。在長距(ju)離(li)頂(ding)(ding)(ding)管(guan)(guan)頂(ding)(ding)(ding)進施(shi)工時，需要安裝中(zhong)繼間以增加頂(ding)(ding)(ding)力完成隧道頂(ding)(ding)(ding)進施(shi)工。當(dang)頂(ding)(ding)(ding)進阻(zu)(zu)力即頂(ding)(ding)(ding)管(guan)(guan)頂(ding)(ding)(ding)進迎(ying)面阻(zu)(zu)力和管(guan)(guan)壁周(zhou)圍摩(mo)擦(ca)阻(zu)(zu)力之(zhi)和超過主(zhu)千(qian)斤頂(ding)(ding)(ding)的允(yun)許總頂(ding)(ding)(ding)力或管(guan)(guan)節允(yun)許的極限壓力或始發(fa)場地(di)背力墻極限反推(tui)力，無法一次達到(dao)頂(ding)(ding)(ding)進距(ju)離(li)要求時，水泥頂(ding)(ding)(ding)管(guan)(guan)廠(chang)家，采用中(zhong)繼接力頂(ding)(ding)(ding)進技(ji)術，實行(xing)分段(duan)實施(shi)使每段(duan)管(guan)(guan)道的頂(ding)(ding)(ding)力降低到(dao)允(yun)許頂(ding)(ding)(ding)力范圍內(nei)。

鋼筋混凝(ning)土(tu)頂(ding)管(guan)(guan)較(jiao)小(xiao)覆土(tu)：一(yi)般要求管(guan)(guan)頂(ding)覆土(tu)大于(yu)(yu)2.5倍的(de)(de)(de)管(guan)(guan)道外直徑，其不得小(xiao)于(yu)(yu)1.5倍的(de)(de)(de)管(guan)(guan)道外直徑。 其次 鋼筋混凝(ning)土(tu)頂(ding)管(guan)(guan)施(shi)(shi)工需防止(zhi)地面(mian)的(de)(de)(de)沉(chen)降或(huo)(huo)隆起：在頂(ding)管(guan)(guan)施(shi)(shi)工沿(yan)線(xian)按一(yi)定(ding)間距布設(she)沉(chen)降觀測(ce)點，監測(ce)頂(ding)管(guan)(guan)頂(ding)進施(shi)(shi)工期間的(de)(de)(de)地面(mian)沉(chen)降量。開挖(wa)端(duan)面(mian)的(de)(de)(de)取土(tu)過多或(huo)(huo)過少，會造成(cheng)地面(mian)的(de)(de)(de)沉(chen)降或(huo)(huo)隆起。為避(bi)免這種不良影(ying)響(xiang)，排污(wu)水泥頂(ding)管(guan)(guan)廠，可采取以下措(cuo)施(shi)(shi)：在壓(ya)漿時要控制好壓(ya)力，恰好能平衡(heng)“泥漿套(tao)”以上土(tu)體的(de)(de)(de)壓(ya)力。嚴格控制管(guan)(guan)道 接口(kou)的(de)(de)(de)密(mi)封質量，防止(zhi)滲漏。在某些管(guan)(guan)節埋藏較(jiao)淺，聊城頂(ding)管(guan)(guan)，離地面(mian)不足1.5米的(de)(de)(de)位置，可采用沿(yan)管(guan)(guan)線(xian)局部壓(ya)鋼板，上堆砂包(bao)加載的(de)(de)(de)形式，防止(zhi)管(guan)(guan)節頂(ding)進時觸變(bian)泥漿上浮使到泥漿套(tao)失效(xiao)。
