要(yao)想(xiang)保證非(fei)開(kai)挖工(gong)(gong)程(cheng)的(de)(de)(de)質量，非(fei)開(kai)挖施工(gong)(gong)工(gong)(gong)程(cheng)公司，施工(gong)(gong)單位應(ying)(ying)做好(hao)充足的(de)(de)(de)準備工(gong)(gong)作(zuo)。施工(gong)(gong)單位應(ying)(ying)對施工(gong)(gong)場所進行(xing)嚴格的(de)(de)(de)現場勘(kan)查，包括地(di)下土(tu)層、管(guan)(guan)線(xian)(xian)和地(di)上(shang)的(de)(de)(de)河(he)流、橋梁(liang)、建(jian)筑物、綠化環境(jing)等(deng)。工(gong)(gong)程(cheng)地(di)質和水文(wen)地(di)質條件沿管(guan)(guan)線(xian)(xian)土(tu)層變(bian)化頻繁，所以(yi)在(zai)頂(ding)管(guan)(guan)施工(gong)(gong)前必(bi)須(xu)了解土(tu)層的(de)(de)(de)變(bian)化情(qing)況:此外對于要(yao)經(jing)過(guo)回填(tian)土(tu)地(di)段，需要(yao)提前加(jia)固處理，以(yi)防頂(ding)管(guan)(guan)施工(gong)(gong)后地(di)表有(you)過(guo)大的(de)(de)(de)下沉。非(fei)開(kai)挖工(gong)(gong)程(cheng)穿越河(he)流、湖(hu)泊、重(zhong)要(yao)交(jiao)通干線(xian)(xian)、重(zhong)要(yao)建(jian)筑物，實現對諸如(ru)供水、煤氣、、污水、電信電纜等(deng)公用管(guan)(guan)線(xian)(xian)的(de)(de)(de)檢測、鋪設、修復與更換的(de)(de)(de)施工(gong)(gong)技術。

由于(yu)地質(zhi)強度不(bu)(bu)同(tong)，需選用(yong)不(bu)(bu)同(tong)的(de)機頭。強度大巖(yan)層，需選用(yong)具有破巖(yan)機頭；普通土(tu)質(zhi)，可以選用(yong)泥(ni)水均衡頂(ding)(ding)管機械進行(xing)施(shi)工(gong)即可。頂(ding)(ding)管機械選型取決于(yu)地質(zhi)勘探(tan)和管徑(jing)。管徑(jing)有800-5000mm鋼筋混凝(ning)土(tu)管，玻璃(li)纖維夾砂管，鋼管之類，依據管徑(jing)大小和資料(liao)不(bu)(bu)同(tong)，選擇不(bu)(bu)同(tong)頂(ding)(ding)進機頭。無論是任務井，亦(yi)或是接納井，均需采用(yong)2次澆(jiao)筑成型的(de)施(shi)工(gong)方案，當次混凝(ning)土(tu)澆(jiao)筑強度到達設計要求，才干停止(zhi)上(shang)部混凝(ning)土(tu)井壁(bi)的(de)澆(jiao)筑，但必需保證延(yan)續澆(jiao)筑，不(bu)(bu)允許(xu)存在施(shi)工(gong)縫(feng)狀況。

頂管(guan)(guan)施(shi)工(gong)(gong)(gong)前(qian)應對管(guan)(guan)道通過(guo)地(di)帶的地(di)質情況認真(zhen)調查(cha)，設置測力裝(zhuang)置，指導糾偏(pian)。糾偏(pian)應按照勤測量(liang)、勤糾偏(pian)、小量(liang)糾的操作(zuo)方法(fa)進(jin)(jin)行(xing)。頂管(guan)(guan)機(ji)(ji)是(shi)(shi)一種使(shi)用(yong)油介質的，所(suo)以需要做好油和機(ji)(ji)器的保(bao)養的工(gong)(gong)(gong)作(zuo)，防止出(chu)現堵塞或(huo)者是(shi)(shi)漏油的現象。在應用(yong)頂管(guan)(guan)機(ji)(ji)的時候，施(shi)工(gong)(gong)(gong)人員要做好隨時觀(guan)察(cha)的工(gong)(gong)(gong)作(zuo)，確認機(ji)(ji)器正常運轉(zhuan)，防止頂管(guan)(guan)機(ji)(ji)出(chu)現故障(zhang)。土(tu)壓平衡式矩(ju)形(xing)(xing)頂管(guan)(guan)頂進(jin)(jin)工(gong)(gong)(gong)法(fa)是(shi)(shi)利(li)用(yong)土(tu)壓平衡矩(ju)形(xing)(xing)頂管(guan)(guan)機(ji)(ji)完成矩(ju)形(xing)(xing)斷面的隧(sui)道施(shi)工(gong)(gong)(gong)，其結構斷面的合(he)理性可減少土(tu)地(di)征(zheng)用(yong)量(liang)和掘(jue)進(jin)(jin)面積，降低(di)工(gong)(gong)(gong)程造(zao)價。可用(yong)于建造(zao)地(di)鐵(tie)車站、地(di)鐵(tie)及水底隧(sui)道旁(pang)通道等(deng)。
