本公司跟您一起分享非(fei)開挖施(shi)工(gong)知(zhi)識：

非開挖頂管工程(cheng)需(xu)要(yao)進(jin)行技術準備，主要(yao)包括對(dui)地下管線(xian)使用現狀(zhuang)的(de)勘察，以準確地掌握(wo)管線(xian)及其他基(ji)礎設施的(de)分布情況；

頂管(guan)工(gong)程按(an)照施工(gong)區域的(de)地(di)形、路線(xian)定出鉆孔軸線(xian)，進行區域地(di)形地(di)貌的(de)勘測(ce)與測(ce)量；對需鉆孔的(de)工(gong)作區域進行地(di)層地(di)質(zhi)的(de)現場(chang)勘查。

非(fei)開挖頂管(guan)工程進行施工場(chang)地(di)的準(zhun)備，對施工場(chang)地(di)進行機(ji)械、機(ji)具等安(an)裝(zhuang)于(yu)堆放；開挖入射作業坑，做好支護(hu)與降水工作；進行施工機(ji)械進場(chang)工作及安(an)裝(zhuang)；借助(zhu)導(dao)航(hang)儀進行探頭導(dao)向的開展(zhan)。

非(fei)開挖頂管工程進行以開孔(kong)、造斜鉆進、保直鉆進為主的(de)導向施(shi)工以及包含孔(kong)徑(jing)設計、分(fen)級擴孔(kong)、孔(kong)壁加固(gu)、回(hui)拉敷管的(de)回(hui)拉擴孔(kong)的(de)兩(liang)個施(shi)工步(bu)驟(zou)。

本公司(si)主營：太(tai)(tai)(tai)原(yuan)頂(ding)(ding)管(guan)(guan)施(shi)(shi)工(gong)(gong)、山(shan)西(xi)(xi)非開挖施(shi)(shi)工(gong)(gong)、山(shan)西(xi)(xi)非開挖管(guan)(guan)道施(shi)(shi)工(gong)(gong)、山(shan)西(xi)(xi)人工(gong)(gong)頂(ding)(ding)管(guan)(guan)施(shi)(shi)工(gong)(gong)、山(shan)西(xi)(xi)過路頂(ding)(ding)管(guan)(guan)施(shi)(shi)工(gong)(gong)、山(shan)西(xi)(xi)巖(yan)石頂(ding)(ding)管(guan)(guan)工(gong)(gong)程、太(tai)(tai)(tai)原(yuan)定向鉆頂(ding)(ding)管(guan)(guan)施(shi)(shi)工(gong)(gong)、山(shan)西(xi)(xi)非開挖頂(ding)(ding)管(guan)(guan)施(shi)(shi)工(gong)(gong)、太(tai)(tai)(tai)原(yuan)泥水(shui)平衡頂(ding)(ding)管(guan)(guan)施(shi)(shi)工(gong)(gong)、頂(ding)(ding)管(guan)(guan)工(gong)(gong)程

本公司跟您一(yi)起分享(xiang)以下內容：

在露天管(guan)道架設工(gong)程中，非開挖(wa)頂(ding)管(guan)施工(gong)工(gong)程在各種土質條(tiao)件下的施工(gong)好，因(yin)此其(qi)應用越來越普遍。但是(shi)(shi)，非開挖(wa)頂(ding)管(guan)施工(gong)中，泥漿管(guan)沉淀堵塞怎么辦？非開挖(wa)施工(gong)中泥管(guan)被(bei)泥沙淤積(ji)堵塞，主要表現是(shi)(shi)泥管(guan)內(nei)泥漿活(huo)動不夠順暢，導致頂(ding)管(guan)機推進不夠順暢。

通(tong)常，頂管(guan)施(shi)工(gong)工(gong)程(cheng)中的泥(ni)漿(jiang)管(guan)會因沉降而堵塞。可(ke)(ke)能的原因包括泥(ni)漿(jiang)泵效率低導(dao)致流量不足，泥(ni)漿(jiang)管(guan)內速度(du)低于(yu)臨界速度(du)，泥(ni)水(shui)沉淀。也可(ke)(ke)能是由于(yu)頂管(guan)機(ji)停止頂推(tui)前對管(guan)道沖洗不，水(shui)泥(ni)管(guan)頂管(guan)工(gong)程(cheng)，也可(ke)(ke)能導(dao)致泥(ni)漿(jiang)沉淀。

假設在(zai)含水(shui)量少的(de)粘土層中頂(ding)管施(shi)工(gong)(gong)工(gong)(gong)程(cheng)，中間繼頂(ding)管工(gong)(gong)程(cheng)，粘土會變成(cheng)泥團，較(jiao)大的(de)泥團會在(zai)管道的(de)彎頭和閥門位置堵塞管道。無論(lun)哪種(zhong)(zhong)情況導致(zhi)管道堵塞，都會影響頂(ding)管機(ji)的(de)正常推進。如果長時間出現這(zhe)種(zhong)(zhong)情況，頂(ding)管機(ji)會下沉，頂(ding)管工(gong)(gong)程(cheng)招標，頂(ding)管質(zhi)量會受到影響。
