頂(ding)管(guan)(guan)施(shi)(shi)工(gong)(gong)(gong)就是(shi)(shi)(shi)非開(kai)挖(wa)(wa)施(shi)(shi)工(gong)(gong)(gong)方(fang)(fang)法(fa)，是(shi)(shi)(shi)一(yi)種不開(kai)挖(wa)(wa)或者少開(kai)挖(wa)(wa)的管(guan)(guan)道埋(mai)設(she)(she)施(shi)(shi)工(gong)(gong)(gong)技術。頂(ding)管(guan)(guan)法(fa)施(shi)(shi)工(gong)(gong)(gong)就是(shi)(shi)(shi)在工(gong)(gong)(gong)作坑內借助于頂(ding)進設(she)(she)備產生的頂(ding)力，克服管(guan)(guan)道與(yu)周圍土(tu)壤的摩擦力，將(jiang)管(guan)(guan)道按設(she)(she)計的坡度頂(ding)入土(tu)中，并將(jiang)土(tu)方(fang)(fang)運走。地(di)下穿越是(shi)(shi)(shi)社會發(fa)展的必(bi)然要(yao)(yao)求。無論(lun)是(shi)(shi)(shi)各(ge)行業部門規(gui)劃不到(dao)位(wei)，協調不好，還(huan)是(shi)(shi)(shi)基建發(fa)展需要(yao)(yao)，新(xin)的地(di)下設(she)(she)施(shi)(shi)總在不斷增加，這時要(yao)(yao)么開(kai)挖(wa)(wa)，要(yao)(yao)么非開(kai)挖(wa)(wa)，必(bi)然選(xuan)擇其(qi)(qi)一(yi)。非開(kai)挖(wa)(wa)工(gong)(gong)(gong)程(cheng)技術解決了管(guan)(guan)道埋(mai)設(she)(she)施(shi)(shi)工(gong)(gong)(gong)中對(dui)城市建筑物的破壞(huai)和道路交通的堵(du)塞等難題，在穩定土(tu)層和環境(jing)保護方(fang)(fang)面凸(tu)顯其(qi)(qi)優勢(shi)。

根據現(xian)場(chang)環境制定 合適的施工(gong)(gong)(gong)方(fang)案(an)，這才是一(yi)家優(you)的頂(ding)(ding)(ding)管(guan)施工(gong)(gong)(gong)廠家的正確做法(fa)，也是保證工(gong)(gong)(gong)程(cheng)(cheng)質量(liang)的首(shou)要前提。沉(chen)井(jing)(jing)，先(xian)施工(gong)(gong)(gong)井(jing)(jing)壁，后(hou)(hou)先(xian)沉(chen)，到設計標高，進(jin)行(xing)封(feng)底(di)；逆(ni)做法(fa)：先(xian)開挖(wa)一(yi)段深(shen)度，后(hou)(hou)做井(jing)(jing)壁，再開挖(wa)一(yi)段深(shen)度，后(hou)(hou)做井(jing)(jing)壁，非(fei)開挖(wa)頂(ding)(ding)(ding)管(guan)施工(gong)(gong)(gong)價格，施工(gong)(gong)(gong)到設計標高進(jin)行(xing)封(feng)底(di)。兩種辦法(fa)各有(you)優(you)點，也有(you)工(gong)(gong)(gong)程(cheng)(cheng)穿插采用施工(gong)(gong)(gong)辦法(fa)。開端啟動機(ji)(ji)械(xie)，將水送(song)入(ru)土(tu)(tu)層(ceng)，同時轉動機(ji)(ji)頭(tou)，將土(tu)(tu)變成泥(ni)漿，抽(chou)出(chu)排出(chu)泥(ni)漿，機(ji)(ji)頭(tou)后(hou)(hou)方(fang)呈現(xian)空(kong)泛，啟動千斤頂(ding)(ding)(ding)將管(guan)道和(he)機(ji)(ji)頭(tou)一(yi)同頂(ding)(ding)(ding)入(ru)土(tu)(tu)層(ceng)。如此循環，將機(ji)(ji)頭(tou)頂(ding)(ding)(ding)至承受井(jing)(jing)，打(da)鑿后(hou)(hou)，吊出(chu)機(ji)(ji)頭(tou)就完成一(yi)段機(ji)(ji)械(xie)頂(ding)(ding)(ding)管(guan)。

頂(ding)管(guan)(guan)(guan)(guan)施(shi)(shi)工(gong)(gong)突出的(de)特點(dian)就是適應性問題(ti)。針對(dui)(dui)不同(tong)的(de)地(di)(di)(di)(di)質情(qing)況、施(shi)(shi)工(gong)(gong)條(tiao)件和(he)設計(ji)要(yao)求(qiu)，選(xuan)(xuan)用與之適應的(de)頂(ding)管(guan)(guan)(guan)(guan)施(shi)(shi)工(gong)(gong)方式(shi)，如何正(zheng)確地(di)(di)(di)(di)選(xuan)(xuan)擇(ze)頂(ding)管(guan)(guan)(guan)(guan)機(ji)和(he)配套(tao)輔助設備，對(dui)(dui)于頂(ding)管(guan)(guan)(guan)(guan)施(shi)(shi)工(gong)(gong)來說將是非常關鍵的(de)。隨著(zhu)我國(guo)經濟持續穩定地(di)(di)(di)(di)增(zeng)長，城(cheng)(cheng)市化(hua)(hua)(hua)進程的(de)進一步加(jia)快，我國(guo)的(de)地(di)(di)(di)(di)下(xia)(xia)管(guan)(guan)(guan)(guan)線的(de)需求(qiu)量(liang)也在逐年增(zeng)加(jia)。加(jia)之人(ren)們對(dui)(dui)環境保護意識的(de)增(zeng)強頂(ding)管(guan)(guan)(guan)(guan)技術將在我國(guo)地(di)(di)(di)(di)下(xia)(xia)管(guan)(guan)(guan)(guan)線的(de)施(shi)(shi)工(gong)(gong)中起(qi)到越(yue)來越(yue)重要(yao)的(de)地(di)(di)(di)(di)位和(he)作用。非開挖技術的(de)發展必(bi)將向規(gui)模化(hua)(hua)(hua)、規(gui)范化(hua)(hua)(hua) 、國(guo)際化(hua)(hua)(hua)的(de)方向發展。地(di)(di)(di)(di)下(xia)(xia)管(guan)(guan)(guan)(guan)線是城(cheng)(cheng)市基(ji)礎設施(shi)(shi)的(de)重要(yao)組成部(bu)分，電(dian)纜管(guan)(guan)(guan)(guan)、上下(xia)(xia)水管(guan)(guan)(guan)(guan)網、熱力(動力)管(guan)(guan)(guan)(guan)道(dao)同(tong)地(di)(di)(di)(di)下(xia)(xia)鐵道(dao)一起(qi)，被稱為城(cheng)(cheng)市的(de)生命線，隨著(zhu)社會的(de)發展，地(di)(di)(di)(di)下(xia)(xia)管(guan)(guan)(guan)(guan)線的(de)長度(du)持續增(zeng)加(jia)。
