小編為您分(fen)享頂管施(shi)工相關知識(shi)：

頂管(guan)施(shi)工(gong)在施(shi)工(gong)之前，首先要針對施(shi)工(gong)現場(chang)環境以及(ji)地下(xia)水位(wei)進行(xing)嚴格的監測，分析(xi)是否(fou)存在復雜的地下(xia)管(guan)線，了解周邊建構筑物的實際(ji)情(qing)況，泥水平衡頂管(guan)施(shi)工(gong)，再結合監測結果，進行(xing)現場(chang)施(shi)工(gong)材料(liao)以及(ji)人員團隊(dui)的布置。

頂管(guan)施工(gong)前對工(gong)程區地(di)下物進行調查、探測，要嚴格標(biao)明地(di)下已(yi)建的(de)管(guan)道(dao)和具體的(de)位置(zhi)，做好標(biao)識，并(bing)且分析管(guan)道(dao)的(de)種類和高程，針對需(xu)要重點(dian)保護的(de)既有良好之物，必(bi)須要由專人進行看護，并(bing)且設置(zhi)明顯標(biao)識和防護欄。未知的(de)管(guan)線必(bi)須要及(ji)時報告相關部門定(ding)位，及(ji)其具體用途和保護方案。對于開(kai)挖(wa)區域(yu)內需(xu)要拆除的(de)地(di)上物，在正式開(kai)挖(wa)前，拆除清理完畢后，方能進行土方開(kai)挖(wa)。

頂管(guan)施工(gong)開(kai)挖(wa)(wa)前(qian)，測(ce)量人員根據(ju)控制網的測(ce)設(she)開(kai)挖(wa)(wa)上開(kai)口線(xian)和(he)溝槽底邊線(xian)，用白灰線(xian)醒目標記(ji)，以此指(zhi)導(dao)機械開(kai)挖(wa)(wa)人員進行作業(ye)。開(kai)挖(wa)(wa)時自(zi)上而下進行，施工(gong)過程中(zhong)(zhong)要(yao)嚴格(ge)結合前(qian)期方(fang)案以及(ji)圖紙的實際要(yao)求(qiu)進行，在施工(gong)過程中(zhong)(zhong)要(yao)嚴格(ge)落實邊坡的控制，避免出現(xian)(xian)超挖(wa)(wa)現(xian)(xian)象(xiang)以及(ji)欠挖(wa)(wa)現(xian)(xian)象(xiang)，滿(man)足施工(gong)圖紙要(yao)求(qiu)的坡度和(he)平整(zheng)度。

小編為您(nin)分享頂管(guan)施工相關知識(shi)：

頂(ding)管(guan)施工(gong)，首先(xian)一定要做好地質工(gong)程的(de)勘察工(gong)作(zuo)，因(yin)為土質發生變化非常頻繁，所以需(xu)要由施工(gong)的(de)人員行土層(ceng)的(de)監(jian)測。如果有回填土，要提(ti)前進行加固，路面頂(ding)管(guan)施工(gong)，防(fang)止后(hou)期(qi)施工(gong)的(de)時候出現下(xia)沉(chen)的(de)問題，給(gei)施工(gong)人員帶(dai)來一定的(de)威脅。

頂管施工地(di)下(xia)水(shui)位距離管底不(bu)能小(xiao)于(yu)0.5m，不(bu)然需要根據現場情況及實地(di)勘測，應做好打(da)井(jing)降水(shui)工作，這對保證工程質量和安全起著非(fei)常(chang)重(zhong)要的作用，井(jing)點必須布(bu)置(zhi)在中(zhong)軸線的兩(liang)端，鑿井(jing)深度應做準(zhun)確的計算。

頂管(guan)施工如(ru)果遇到挖土工作面塌方或(huo)遇到障礙物、后(hou)背變形或(huo)傾斜、管(guan)位偏差超限、頂力突然增大時應(ying)停(ting)止工作，處理后(hou)再施頂。
