頂(ding)(ding)管機是一種使用(yong)油(you)介質的(de)(de)，所(suo)以需要(yao)(yao)做好油(you)和機器(qi)(qi)的(de)(de)保養的(de)(de)工作(zuo)，防止出(chu)現(xian)(xian)堵塞或(huo)者是漏(lou)油(you)的(de)(de)現(xian)(xian)象。在(zai)應用(yong)頂(ding)(ding)管機的(de)(de)時候(hou)，施工人員要(yao)(yao)做好隨(sui)時觀(guan)察的(de)(de)工作(zuo)，確認(ren)機器(qi)(qi)正常(chang)運轉(zhuan)，防止頂(ding)(ding)管機出(chu)現(xian)(xian)故障。頂(ding)(ding)管掘(jue)進機前方遇到(dao)障礙；后背墻變形(xing)嚴重；頂(ding)(ding)鐵(tie)發(fa)生(sheng)扭曲現(xian)(xian)象；管位(wei)偏差過(guo)大且校正無效；頂(ding)(ding)力超過(guo)管端(duan)的(de)(de)允許頂(ding)(ding)力；油(you)泵、油(you)路發(fa)生(sheng)異常(chang)現(xian)(xian)象；接縫中漏(lou)泥(ni)(ni)漿(jiang)。現(xian)(xian)在(zai)比較(jiao)常(chang)用(yong)頂(ding)(ding)管施工為(wei)泥(ni)(ni)水平衡(heng)頂(ding)(ding)管施工法，其施工原(yuan)理(li)：通過(guo)導向頭的(de)(de)刀削轉(zhuan)動(dong)功能將(jiang)泥(ni)(ni)土(tu)、砂、石破碎，由一條(tiao)鋼(gang)管注入水量，拌(ban)成漿(jiang)液，由另一條(tiao)鋼(gang)管吸出(chu)漿(jiang)液。

非開挖具有環保(bao)宜居等(deng)競爭優勢。一(yi)個(ge)城市的(de)開挖量超過(guo)一(yi)定比例，必然影響(xiang)交通和(he)市民(min)正常(chang)生(sheng)活。而非開挖施工不阻礙交通、不污染(ran)環境、不破壞植(zhi)被、不影響(xiang)周邊建筑物、不影響(xiang)居民(min)的(de)一(yi)切正常(chang)生(sheng)活和(he)工作秩序。經過(guo)多年的(de)發展，頂管(guan)(guan)(guan)技術在(zai)我國已(yi)得(de)到(dao)大量地實際(ji)工程應用，且保(bao)持著(zhu)(zhu)高速的(de)增長(chang)勢頭，無論在(zai)技術上、頂管(guan)(guan)(guan)設備還(huan)是(shi)施工工藝(yi)上取得(de)了(le)很大的(de)進步，非開挖施工工程有限(xian)公(gong)司，在(zai)某些方面(mian)甚至(zhi)已(yi)達到(dao)了(le)水平。地下管(guan)(guan)(guan)線是(shi)城市基礎設施的(de)重要組成部(bu)分，電(dian)纜管(guan)(guan)(guan)、上下水管(guan)(guan)(guan)網(wang)、熱力(li)(動(dong)力(li))管(guan)(guan)(guan)道同地下鐵道一(yi)起(qi)，被稱為城市的(de)生(sheng)命線，隨著(zhu)(zhu)社會(hui)的(de)發展，地下管(guan)(guan)(guan)線的(de)長(chang)度持續(xu)增加。

根據地質報(bao)告，并結合的(de)(de)施工(gong)經(jing)驗，頂(ding)(ding)(ding)(ding)(ding)管(guan)機頭決定采用(yong)(yong)氣壓平衡(heng)網格（水沖）式機頭進(jin)(jin)行(xing)施工(gong)。該機頭在頂(ding)(ding)(ding)(ding)(ding)進(jin)(jin)過程(cheng)中(zhong)(zhong)，通過氣壓平衡(heng)正面(mian)土(tu)壓穩(wen)定機頭，減少(shao)外部土(tu)體對(dui)周圍地面(mian)的(de)(de)影響。采用(yong)(yong)4臺200噸/臺千斤頂(ding)(ding)(ding)(ding)(ding)作為主頂(ding)(ding)(ding)(ding)(ding)，千斤頂(ding)(ding)(ding)(ding)(ding)行(xing)程(cheng)為1.4米。千斤頂(ding)(ding)(ding)(ding)(ding)動力(li)由油泵提(ti)供。千斤頂(ding)(ding)(ding)(ding)(ding)后端(duan)用(yong)(yong)道(dao)木和分壓環將反力(li)均(jun)勻作用(yong)(yong)于工(gong)作井，前端(duan)頂(ding)(ding)(ding)(ding)(ding)進(jin)(jin)分壓環，頂(ding)(ding)(ding)(ding)(ding)鐵將頂(ding)(ding)(ding)(ding)(ding)力(li)傳(chuan)至管(guan)節。分壓環制作具有足夠(gou)的(de)(de)剛性，與管(guan)端(duan)面(mian)接(jie)觸相對(dui)平整，無(wu)變(bian)形(xing)。在長距(ju)離頂(ding)(ding)(ding)(ding)(ding)進(jin)(jin)過程(cheng)中(zhong)(zhong)，當頂(ding)(ding)(ding)(ding)(ding)進(jin)(jin)阻力(li)超過容許總頂(ding)(ding)(ding)(ding)(ding)力(li)時(shi)，無(wu)法一(yi)次(ci)達(da)到頂(ding)(ding)(ding)(ding)(ding)進(jin)(jin)距(ju)離時(shi)，須設置中(zhong)(zhong)繼(ji)間分段(duan)接(jie)力(li)頂(ding)(ding)(ding)(ding)(ding)進(jin)(jin)。
