小(xiao)編為您(nin)分享馬路(lu)頂管施工相關知識：

頂管法是借助頂推設備將(jiang)工具管或掘進(jin)機從任務坑(始發井)內(nei)穿過(guo)土層(ceng)不斷(duan)推到接納坑(抵達井)內(nei)，依托(tuo)裝置(zhi)在管道(dao)頭部的(de)(de)鉆掘系(xi)統不時(shi)地切削土屑，由出(chu)土系(xi)統將(jiang)切削的(de)(de)土屑排出(chu)，邊頂進(jin)，邊切削，邊保送，將(jiang)管道(dao)逐段向(xiang)前鋪設，與此同時(shi)，把緊隨工具管或掘進(jin)機后的(de)(de)管道(dao)埋設在兩坑之間的(de)(de)一種非開挖施工技術。

人工頂(ding)(ding)管(guan)施(shi)工前應仔細熟習圖(tu)紙，馬(ma)路(lu)頂(ding)(ding)管(guan)施(shi)工每米多少錢，然后(hou)停止(zhi)頂(ding)(ding)管(guan)軸(zhou)線的定位，任務(wu)坑(keng)的 放(fang)樣及(ji)停止(zhi)高(gao)程測(ce)量。依(yi)據己施(shi)放(fang)軸(zhou)線及(ji)立(li)體位臵，預埋導軌。軌道(dao)裝(zhuang)置終了后(hou)即停止(zhi)頂(ding)(ding)管(guan)設(she)備(bei)、液(ye)壓千(qian)斤頂(ding)(ding)的裝(zhuang)置調試(shi)，同時在沉井(jing)上架(jia)設(she)龍門(men)架(jia)起(qi)重(zhong)設(she)備(bei)、液(ye)壓油箱及(ji)動力設(she)備(bei)的裝(zhuang)置。待砼底(di)板(ban)強度到(dao)達設(she)計要求的強度后(hou)開端進行管(guan)道(dao)頂(ding)(ding)進。

小編為您分享馬路(lu)頂管(guan)施工相(xiang)關知(zhi)識：馬路(lu)頂管(guan)施工中地表沉降(jiang)或隆(long)起的(de)原因：

①頂管機正(zheng)面(mian)土(tu)體失衡引起的地面(mian)沉降與隆(long)起。

馬路頂(ding)管施(shi)(shi)工中，受(shou)到土(tu)質變化等(deng)因素(su)影(ying)響不(bu)能正確(que)把握土(tu)壓(ya)所致。另(ling)外非(fei)開(kai)挖施(shi)(shi)工中頂(ding)管機(ji)刀盤(pan)切削面(mian)積過小、推進速度調整不(bu)當等(deng)，也容易造成土(tu)壓(ya)失衡引起地面(mian)沉(chen)降與隆起。

②管道外(wai)周空隙引起的地面(mian)沉降與(yu)隆起。

馬路頂(ding)(ding)管(guan)(guan)(guan)施(shi)工(gong)中，頂(ding)(ding)管(guan)(guan)(guan)機進(jin)行(xing)(xing)糾偏或曲(qu)線頂(ding)(ding)進(jin)時(shi)，馬路頂(ding)(ding)管(guan)(guan)(guan)施(shi)工(gong)流程，往往會形成空隙，忻州(zhou)馬路頂(ding)(ding)管(guan)(guan)(guan)施(shi)工(gong)，周邊(bian)土體填充空隙，則容(rong)易導(dao)致(zhi)地(di)面(mian)沉降(jiang)。若(ruo)采用觸變泥漿(jiang)減摩(mo)技術(shu)進(jin)行(xing)(xing)頂(ding)(ding)管(guan)(guan)(guan)施(shi)工(gong)，注(zhu)漿(jiang)不(bu)及時(shi)也(ye)容(rong)易導(dao)致(zhi)地(di)面(mian)沉降(jiang)。

③管道與周(zhou)圍土體摩擦(ca)引(yin)起(qi)的地面沉降(jiang)與隆(long)起(qi)。

馬路(lu)頂(ding)管(guan)施工中，管(guan)道(dao)在推進時會與周(zhou)圍土體產(chan)(chan)生摩擦，當(dang)管(guan)節外形不整、接口不平(ping)或(huo)管(guan)道(dao)不直順(shun)時，摩擦產(chan)(chan)生的(de)擾動就會加劇，容易引起地面沉降(jiang)與隆起。

④管(guan)道(dao)接口滲漏引起(qi)的地(di)面(mian)沉降與隆起(qi)。

馬路頂管(guan)施工中，管(guan)道接口密封圈安置不(bu)當或管(guan)端受力(li)不(bu)勻而(er)破壞等原因(yin)，都會導致水土流失(shi)，從(cong)而(er)造成地面沉降(jiang)與隆起。

頂管施(shi)工工程的優點(dian)是什么？

1、可(ke)以穿越障(zhang)礙物：

此項目施(shi)工中間線位于綠(lv)化帶內(nei)，而綠(lv)化帶內(nei)多為(wei)高大挺拔的喬木，若(ruo)采用(yong)開槽施(shi)工，則需要全(quan)部進(jin)行移除和回栽(zai)，費(fei)用(yong)較高；

2、建(jian)設公害(hai)少、文明施(shi)工(gong)程度(du)比開槽(cao)施(shi)工(gong)高：

此(ci)項目(mu)為穿越馬路頂(ding)(ding)管(guan)工(gong)程(cheng)(cheng)，采用頂(ding)(ding)管(guan)施工(gong)方案(an)則可以減少(shao)(shao)噪音和振動(dong)，減少(shao)(shao)對附(fu)近居民的(de)生活(huo)干擾(rao)，減少(shao)(shao)建設(she)公害(hai)，大(da)大(da)的(de)提(ti)高了文(wen)明(ming)施工(gong)程(cheng)(cheng)度不同，有效的(de)維護了工(gong)程(cheng)(cheng)形象；
