經過多(duo)年的(de)發展，頂管(guan)技術(shu)(shu)在我國已得(de)到(dao)(dao)大量(liang)地實際(ji)工(gong)(gong)(gong)程應用，且保持著高速(su)的(de)增長勢(shi)頭，無論(lun)在技術(shu)(shu)上、頂管(guan)設(she)備(bei)還是施工(gong)(gong)(gong)工(gong)(gong)(gong)藝上取得(de)了很(hen)大的(de)進(jin)步(bu)，在某些(xie)方(fang)面甚至已達(da)到(dao)(dao)了水(shui)平。頂管(guan)施工(gong)(gong)(gong)借助于主(zhu)頂油缸及(ji)管(guan)道間(jian)(jian)中繼間(jian)(jian)等的(de)推(tui)(tui)力，把工(gong)(gong)(gong)具(ju)(ju)管(guan)或掘進(jin)機從工(gong)(gong)(gong)作井內穿過土層一(yi)直推(tui)(tui)到(dao)(dao)接收井內吊起。與此同(tong)時，也就(jiu)把緊隨工(gong)(gong)(gong)具(ju)(ju)管(guan)或掘進(jin)機后的(de)管(guan)道埋設(she)在兩井之間(jian)(jian)，以期實現(xian)非開(kai)挖(wa)敷(fu)設(she)地下管(guan)道的(de)施工(gong)(gong)(gong)方(fang)法。非開(kai)挖(wa)具(ju)(ju)有環保宜居(ju)等競爭優勢(shi)。一(yi)個城市的(de)開(kai)挖(wa)量(liang)超過一(yi)定比例，非開(kai)挖(wa)施工(gong)(gong)(gong)工(gong)(gong)(gong)程報價，必然影響交(jiao)通(tong)和(he)市民正(zheng)常(chang)生活。而非開(kai)挖(wa)施工(gong)(gong)(gong)不阻礙交(jiao)通(tong)、不污(wu)染環境(jing)、不破壞植(zhi)被、不影響周邊(bian)建筑(zhu)物(wu)、不影響居(ju)民的(de)一(yi)切正(zheng)常(chang)生活和(he)工(gong)(gong)(gong)作秩序(xu)。

頂管(guan)機(ji)通常用于(yu)小直徑斷面巖(yan)石和土體掘進，其(qi)中心就是將(jiang)一(yi)些本來集(ji)成在(zai)盾構機(ji)外部的(de)功(gong)用部件拿出(chu)來，以減少其(qi)尺寸，頂推安裝在(zai)任務井(jing)里(li)。穿(chuan)(chuan)越(yue)建(jian)筑(zhu)時對(dui)(dui)基(ji)(ji)(ji)礎(chu)的(de)探(tan)查頂管(guan)在(zai)建(jian)筑(zhu)物基(ji)(ji)(ji)礎(chu)下施工時，需要(yao)(yao)明確(que)施工施工路線(xian)上所遇(yu)到(dao)的(de)基(ji)(ji)(ji)礎(chu)類型(xing)，對(dui)(dui)于(yu)部分基(ji)(ji)(ji)礎(chu)頂管(guan)頂進前可(ke)采取托換、加固措施。非(fei)開挖(wa)工程穿(chuan)(chuan)越(yue)河流、湖泊、重要(yao)(yao)交(jiao)通干線(xian)、重要(yao)(yao)建(jian)筑(zhu)物，實現對(dui)(dui)諸(zhu)如(ru)供水、煤氣、、污水、電(dian)信(xin)電(dian)纜等公(gong)用管(guan)線(xian)的(de)檢測(ce)、鋪設、修復(fu)與更換的(de)施工技術。

頂管(guan)施(shi)(shi)工(gong)(gong)(gong)(gong)降(jiang)低(di)交通壓力。對城(cheng)市交通攪擾小，施(shi)(shi)工(gong)(gong)(gong)(gong)面由線縮(suo)成(cheng)點，占(zhan)地面積(ji)小，且(qie)不會招致路(lu)面沉降(jiang)以(yi)致發(fa)生裂(lie)紋，防止(zhi)了(le)路(lu)面重修。無論是(shi)任務井，亦或(huo)是(shi)接納井，均需(xu)采(cai)用2次澆(jiao)筑成(cheng)型的(de)(de)施(shi)(shi)工(gong)(gong)(gong)(gong)方案，當次混凝(ning)(ning)土(tu)澆(jiao)筑強度到達設計要求，才(cai)干停止(zhi)上部混凝(ning)(ning)土(tu)井壁的(de)(de)澆(jiao)筑，但必需(xu)保(bao)證延續(xu)澆(jiao)筑，不允許存在施(shi)(shi)工(gong)(gong)(gong)(gong)縫狀況。施(shi)(shi)工(gong)(gong)(gong)(gong)人員更應經(jing)過嚴格培訓(xun)，熟練掌握施(shi)(shi)工(gong)(gong)(gong)(gong)技巧，保(bao)證施(shi)(shi)工(gong)(gong)(gong)(gong)順利進行，人員在頂管(guan)內操作(zuo)的(de)(de)情(qing)況下(xia)，需(xu)要定時監測管(guan)內有毒(du)體含量。
