定向鉆進穿越施工

1)管道工程(cheng)采(cai)用無線傳(chuan)輸(shu)儀器進行隨鉆(zhan)測(ce)量，免除有線傳(chuan)輸(shu)帶來的距離限制，在井眼(yan)位置(zhi)安(an)裝信(xin)號(hao)接收儀器，及時(shi)反饋軌道監測(ce)數據以及掌握(wo)鉆(zhan)向(xiang)動態。

2)管道工程(cheng)根據(ju)土層情況設(she)定旋(xuan)轉鉆頭方向(xiang)參數(shu)以及孔底馬達的動力參數(shu)，結合遠程(cheng)操(cao)控平臺智能化(hua)進(jin)行(xing)鉆進(jin)穿越施(shi)工。

3)定(ding)向鉆(zhan)進穿越(yue)法適合(he)的地層條件為砂(sha)土(tu)(tu)、粉(fen)土(tu)(tu)、粘性(xing)土(tu)(tu)、卵石等地況(kuang)。在不開挖(wa)地表面條件下，可廣泛應用(yong)于供水(shui)、煤氣、電力、電訊、、石油等管線鋪設施工。

小編為您分享管道工程相關(guan)知(zhi)識：

拉(la)管(guan)施工的質量控制方法及要求

a、路(lu)面(mian)建筑物(wu)及管(guan)(guan)道鋪設區域無塌(ta)陷(xian)，忻州管(guan)(guan)道工(gong)程，施(shi)工(gong)后進行雷達掃描檢測，不得低于90%。

b、管(guan)道工(gong)程管(guan)道鋪設規定要求：PE管(guan)鋪設滿足排氣要求，PE管(guan)無向上的折點。水平大(da)偏差±0.3m。縱(zong)向垂直(zhi)大(da)偏差±0.25m。保(bao)持管(guan)內壁干凈(jing)，拉管(guan)過程中封堵內壁。

c、管道工程(cheng)拉(la)管過程(cheng)中，操作手嚴格按照(zhao)地面(mian)預(yu)布(bu)控制(zhi)樁的平面(mian)位(wei)置和高程(cheng)控制(zhi)鉆頭(tou)走向(xiang)，每隔水平距離3米校核一次。

d、管道(dao)內底高(gao)程(cheng)的復測，管道(dao)拉通后，應(ying)對管道(dao)內底高(gao)程(cheng)進行復合測量。用(yong)鉆(zhan)(zhan)機將裝有探測器(qi)(qi)的鉆(zhan)(zhan)頭在(zai)管道(dao)內拉動，試驗人員根(gen)據探測器(qi)(qi)發出的信(xin)號來確定鉆(zhan)(zhan)頭的深度，經過換(huan)算(suan)后即(ji)計(ji)算(suan)出管內底高(gao)程(cheng)；得出的結果和原始控制軌跡高(gao)程(cheng)進行比較(jiao)，就得到(dao)各樁位高(gao)程(cheng)偏差數(shu)值。

管(guan)(guan)(guan)道(dao)(dao)(dao)工程(cheng)(cheng)過(guo)程(cheng)(cheng)中，由于不(bu)時(shi)受到機頭運動、紅(hong)色偏(pian)差(cha)(cha)等影響，水泥管(guan)(guan)(guan)道(dao)(dao)(dao)工程(cheng)(cheng)報(bao)價，管(guan)(guan)(guan)道(dao)(dao)(dao)軌(gui)跡(ji)呈不(bu)規則曲線(xian)。，因此(ci)管(guan)(guan)(guan)道(dao)(dao)(dao)的曲線(xian)會(hui)發生變(bian)(bian)化(hua)(hua)，但如(ru)果在(zai)頂(ding)進過(guo)程(cheng)(cheng)中不(bu)能控制管(guan)(guan)(guan)道(dao)(dao)(dao)曲線(xian)的變(bian)(bian)化(hua)(hua)范圍(wei)，造(zao)成軌(gui)跡(ji)偏(pian)差(cha)(cha)過(guo)大(da)，會(hui)造(zao)成機頭驗收困難(nan)(nan)，還會(hui)因管(guan)(guan)(guan)道(dao)(dao)(dao)的變(bian)(bian)化(hua)(hua)造(zao)成頂(ding)進困難(nan)(nan)，輸氣管(guan)(guan)(guan)道(dao)(dao)(dao)工程(cheng)(cheng)多(duo)少錢(qian)，在(zai)過(guo)大(da)的頂(ding)進力作(zuo)用下破壞管(guan)(guan)(guan)道(dao)(dao)(dao)。此(ci)外(wai)，在(zai)覆蓋較淺(qian)或地質(zhi)條(tiao)件(jian)較差(cha)(cha)的地區，也(ye)容易造(zao)成空氣變(bian)(bian)形(xing)等二次事故。
