頂(ding)(ding)(ding)進(jin)施(shi)工(gong)(gong)進(jin)程(cheng)中應嚴厲留(liu)意(yi)以下內容：頂(ding)(ding)(ding)進(jin)時(shi)，頂(ding)(ding)(ding)鐵上不(bu)準站人(ren)；頂(ding)(ding)(ding)進(jin)就位后(hou)(hou)，應立即回復施(shi)工(gong)(gong)線(xian)路；頂(ding)(ding)(ding)進(jin)施(shi)工(gong)(gong)完成(cheng)(cheng)后(hou)(hou)，施(shi)工(gong)(gong)人(ren)員(yuan)必需對管(guan)道線(xian)路停止片(pian)面修(xiu)整與(yu)穩固，并停止相關實驗。非(fei)開挖(wa)技(ji)(ji)術(shu)是極為重(zhong)要的一種都市(shi)鋪(pu)設(she)管(guan)道的施(shi)工(gong)(gong)手段，采用非(fei)開挖(wa)技(ji)(ji)術(shu)鋪(pu)設(she)管(guan)道具有若干得天獨厚的優勢。在城市(shi)建設(she)中非(fei)開挖(wa)技(ji)(ji)術(shu)已經(jing)成(cheng)(cheng)為了主(zhu)流，但是在實施(shi)非(fei)開挖(wa)工(gong)(gong)程(cheng)時(shi)一定要注意(yi)微(wei)小的細(xi)節，避免出現一些的意(yi)外。這樣不(bu)僅會(hui)耽誤工(gong)(gong)程(cheng)的進(jin)程(cheng)，非(fei)開挖(wa)頂(ding)(ding)(ding)管(guan)施(shi)工(gong)(gong)設(she)備(bei)，造成(cheng)(cheng)成(cheng)(cheng)本，而且還會(hui)給對人(ren)員(yuan)安全造成(cheng)(cheng)傷害(hai)，因(yin)此一定要注意(yi)安全。

非開(kai)(kai)挖工程技術解決了管(guan)(guan)道(dao)埋設(she)(she)施工中(zhong)對城(cheng)市建筑物的破(po)壞和(he)(he)道(dao)路交(jiao)通(tong)的堵塞等難題，在(zai)穩定(ding)土層和(he)(he)環境保護方面(mian)凸顯其(qi)優勢。這對交(jiao)通(tong)繁忙、人口密集、地(di)面(mian)建筑物眾多、地(di)下(xia)(xia)管(guan)(guan)線復雜的城(cheng)市是非常重(zhong)要的，它將為城(cheng)市創造一(yi)(yi)個潔凈(jing)、舒適和(he)(he)美(mei)好的環境。若管(guan)(guan)道(dao)右偏，主頂(ding)(ding)千(qian)斤頂(ding)(ding)右伸(shen)(shen)左縮，反之亦然(ran)。若高(gao)程與(yu)左右同時有偏差，則(ze)優先(xian)糾正(zheng)偏差大的一(yi)(yi)面(mian)。頂(ding)(ding)管(guan)(guan)放線準(zhun)(zhun)確(que)就能保證頂(ding)(ding)管(guan)(guan)能按設(she)(she)計要求準(zhun)(zhun)確(que)進(jin)洞。它的技術要點在(zai)于(yu)糾正(zheng)管(guan)(guan)子在(zai)地(di)下(xia)(xia)延伸(shen)(shen)的偏差。特別(bie)適用于(yu)大中(zhong)型管(guan)(guan)徑的非開(kai)(kai)挖鋪(pu)設(she)(she)。具有經濟、，保護環境的綜合功能。

目前，頂(ding)管(guan)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)常(chang)(chang)采用(yong)(yong)的施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)方(fang)法(fa)分為敞開(kai)(kai)人工(gong)(gong)(gong)手(shou)掘式(shi)和密封機械式(shi)頂(ding)管(guan)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)方(fang)法(fa)，其中機械式(shi)頂(ding)管(guan)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)常(chang)(chang)用(yong)(yong)的施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)方(fang)法(fa)又有(you)泥水(shui)平(ping)衡(heng)(heng)式(shi)和土壓平(ping)衡(heng)(heng)式(shi)兩種，頂(ding)管(guan)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)常(chang)(chang)用(yong)(yong)的管(guan)材有(you)砼管(guan)、鋼(gang)管(guan)、玻璃夾砂(sha)鋼(gang)管(guan)。非(fei)開(kai)(kai)挖(wa)技術是才開(kai)(kai)始頻繁使(shi)用(yong)(yong)的一個術語，它涉(she)及的是利用(yong)(yong)少開(kai)(kai)挖(wa)，即工(gong)(gong)(gong)作井(jing)與接(jie)收井(jing)要開(kai)(kai)挖(wa)，以及不(bu)開(kai)(kai)挖(wa)，即管(guan)道不(bu)開(kai)(kai)挖(wa)技術來進行(xing)地(di)下管(guan)線的鋪設(she)或更換，頂(ding)管(guan)直徑DN800—4500。頂(ding)管(guan)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)單位施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)設(she)備、技術、管(guan)理水(shui)平(ping)參差不(bu)齊(qi)，在施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)中常(chang)(chang)出現(xian)一些問題，影(ying)響(xiang)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)質(zhi)量。頂(ding)管(guan)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)時不(bu)用(yong)(yong)封路施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)，選用(yong)(yong)的工(gong)(gong)(gong)作井(jing)與接(jie)受井(jing)又位于閑置之處，頂(ding)進過程中路上交(jiao)通照(zhao)常(chang)(chang)通行(xing)。
