根據地質報告，非開(kai)挖頂(ding)管(guan)(guan)(guan)施(shi)工(gong)報價，并結(jie)合(he)的(de)(de)施(shi)工(gong)經驗(yan)，頂(ding)管(guan)(guan)(guan)機(ji)頭決定(ding)采用氣壓平衡(heng)網格(ge)（水沖）式(shi)機(ji)頭進(jin)(jin)行施(shi)工(gong)。該機(ji)頭在頂(ding)進(jin)(jin)過(guo)(guo)程(cheng)中(zhong)(zhong)，通過(guo)(guo)氣壓平衡(heng)正面(mian)土壓穩定(ding)機(ji)頭，減少外部土體對周圍地面(mian)的(de)(de)影響(xiang)。一節(jie)管(guan)(guan)(guan)子完成(cheng)頂(ding)入土層之后，再下第二節(jie)管(guan)(guan)(guan)子繼續頂(ding)進(jin)(jin)。其原理(li)是借(jie)助于主(zhu)頂(ding)油缸及管(guan)(guan)(guan)道(dao)間、中(zhong)(zhong)繼間等推力，把工(gong)具(ju)管(guan)(guan)(guan)或(huo)掘進(jin)(jin)機(ji)從工(gong)作(zuo)坑內穿過(guo)(guo)土層一直(zhi)推進(jin)(jin)到接收坑內吊起。管(guan)(guan)(guan)道(dao)緊(jin)隨(sui)工(gong)具(ju)管(guan)(guan)(guan)或(huo)掘進(jin)(jin)機(ji)后，埋設在兩(liang)坑之間。隨(sui)著我國(guo)經濟持續穩定(ding)地增(zeng)(zeng)長，城市(shi)化進(jin)(jin)程(cheng)的(de)(de)進(jin)(jin)一步加快，我國(guo)的(de)(de)地下管(guan)(guan)(guan)線的(de)(de)需求量也在逐年增(zeng)(zeng)加。加之人們對環境保護(hu)意識的(de)(de)增(zeng)(zeng)強頂(ding)管(guan)(guan)(guan)技術將(jiang)在我國(guo)地下管(guan)(guan)(guan)線的(de)(de)施(shi)工(gong)中(zhong)(zhong)起到越來越重要(yao)的(de)(de)地位和作(zuo)用。非開(kai)挖技術的(de)(de)發展必將(jiang)向規(gui)模化、規(gui)范(fan)化 、國(guo)際化的(de)(de)方向發展。

采(cai)(cai)用通(tong)風裝(zhuang)置(zhi)予以解決(jue)。前探查(cha)地(di)下管(guan)(guan)(guan)(guan)線(xian)盡管(guan)(guan)(guan)(guan)的頂(ding)(ding)管(guan)(guan)(guan)(guan)設備具有(you)在施(shi)工時探查(cha)前進路線(xian)不遠距離管(guan)(guan)(guan)(guan)線(xian)的能力，確保公眾正(zheng)常(chang)生活仍有(you)必(bi)要(yao)。開端啟動(dong)機械，將水(shui)送入(ru)土(tu)層，同時轉動(dong)機頭(tou)，將土(tu)變成(cheng)泥(ni)漿，抽出排出泥(ni)漿，機頭(tou)后方呈現空泛，啟動(dong)千斤(jin)頂(ding)(ding)將管(guan)(guan)(guan)(guan)道和機頭(tou)一(yi)同頂(ding)(ding)入(ru)土(tu)層。如此循(xun)環，將機頭(tou)頂(ding)(ding)至(zhi)承受井，打鑿后，吊出機頭(tou)就完成(cheng)一(yi)段(duan)機械頂(ding)(ding)管(guan)(guan)(guan)(guan)。有(you)毒體(ti)的檢測(ce)與防護頂(ding)(ding)管(guan)(guan)(guan)(guan)施(shi)工的地(di)層一(yi)般會(hui)通(tong)過(guo)淤泥(ni)層，腐爛動(dong)、植物體(ti)會(hui)在地(di)下形成(cheng)有(you)毒體(ti)聚集體(ti)，危害施(shi)工人員(yuan)的健康(kang)和生命，所以有(you)人員(yuan)在頂(ding)(ding)管(guan)(guan)(guan)(guan)內(nei)操作的情況下，需要(yao)定時監測(ce)管(guan)(guan)(guan)(guan)內(nei)有(you)毒體(ti)含(han)量，采(cai)(cai)用通(tong)風裝(zhuang)置(zhi)予以解決(jue)。

頂管(guan)(guan)施工(gong)(gong)是一種在(zai)不開(kai)挖(wa)或許少開(kai)挖(wa)路面的(de)(de)(de)狀況(kuang)下(xia)，埋設(she)管(guan)(guan)道的(de)(de)(de)施工(gong)(gong)技術，可解決管(guan)(guan)道埋設(she)施工(gong)(gong)對城市(shi)建筑(zhu)物的(de)(de)(de)毀壞和形成交通堵塞的(de)(de)(de)難題，在(zai)波動土(tu)層(ceng)和環境保(bao)護(hu)方(fang)具有優(you)勢(shi)。頂管(guan)(guan)施工(gong)(gong)降低工(gong)(gong)程總造價。可浪(lang)費少量土(tu)方(fang)工(gong)(gong)程、溝(gou)管(guan)(guan)基座資料，增加基坑支護(hu)作業的(de)(de)(de)工(gong)(gong)程量，增加開(kai)挖(wa)、回填(tian)和路面修復。由于(yu)地質(zhi)強(qiang)度不同(tong)，需選用(yong)不同(tong)的(de)(de)(de)機(ji)頭(tou)。強(qiang)度大巖層(ceng)，需選用(yong)具有破(po)巖機(ji)頭(tou)；普通土(tu)質(zhi)，可以選用(yong)泥水均(jun)衡頂管(guan)(guan)機(ji)械進(jin)行施工(gong)(gong)即可。
