頂管施工中存在由于地質條件變化、地下地上管線、距離構筑物近、有毒有害氣體等復雜作業環境而引發的風險，內蒙古頂管施工是一種非開挖敷設管道的技術，由于它不需要開挖面層，能穿越地面構筑物和地下管線及公路、鐵路、河道，節省大量投資和時間，對城區的交通、噪音、粉塵的危害和影響大大降低，因此，近年來它被廣泛應用于市政工程敷設大量給排水、煤氣、電力和通信管道等工程。

頂(ding)(ding)管(guan)(guan)(guan)施工(gong)(gong)是(shi)在(zai)(zai)管(guan)(guan)(guan)道(dao)的(de)沿線按設(she)計方案設(she)置(zhi)工(gong)(gong)作(zuo)井(jing)和接(jie)收(shou)(shou)井(jing)，工(gong)(gong)作(zuo)井(jing)內設(she)置(zhi)足夠(gou)強(qiang)度的(de)后(hou)靠(kao)背，吊進(jin)工(gong)(gong)具頭(tou)、油(you)壓(ya)千(qian)斤頂(ding)(ding)及(ji)要頂(ding)(ding)進(jin)的(de)鋼管(guan)(guan)(guan)或鋼筋混(hun)(hun)凝土管(guan)(guan)(guan)，接(jie)好照明(ming)、泥(ni)漿(jiang)管(guan)(guan)(guan)、油(you)管(guan)(guan)(guan)等管(guan)(guan)(guan)線，然后(hou)用油(you)壓(ya)千(qian)斤頂(ding)(ding)緩慢頂(ding)(ding)進(jin)，通過(guo)壓(ya)漿(jiang)系統(tong)使管(guan)(guan)(guan)節周圍形成泥(ni)漿(jiang)套(tao)，管(guan)(guan)(guan)道(dao)在(zai)(zai)泥(ni)漿(jiang)套(tao)中(zhong)滑行。在(zai)(zai)頂(ding)(ding)進(jin)過(guo)程中(zhong)通過(guo)激(ji)光經緯儀(yi)測量頂(ding)(ding)管(guan)(guan)(guan)的(de)方向，邊(bian)頂(ding)(ding)進(jin)邊(bian)排(pai)土邊(bian)糾偏，直至(zhi)將鋼管(guan)(guan)(guan)或鋼筋混(hun)(hun)凝土管(guan)(guan)(guan)頂(ding)(ding)至(zhi)接(jie)收(shou)(shou)井(jing)內。
