填充是(shi)泥(ni)漿在非(fei)開挖(wa)施(shi)工現場(chang)的主要作(zuo)(zuo)用之一，泥(ni)漿在非(fei)開挖(wa)頂(ding)管(guan)施(shi)工中(zhong)的另一個作(zuo)(zuo)用，就(jiu)是(shi)潤滑。頂(ding)管(guan)機(ji)在泥(ni)土中(zhong)進(jin)行頂(ding)進(jin)，大同頂(ding)管(guan)施(shi)工，這個過程中(zhong)，頂(ding)管(guan)與(yu)泥(ni)土之間(jian)會產生摩擦，影響(xiang)頂(ding)管(guan)機(ji)進(jin)入。有了泥(ni)漿作(zuo)(zuo)為潤滑劑，非(fei)開挖(wa)頂(ding)管(guan)施(shi)工方案(an)，頂(ding)管(guan)機(ji)就(jiu)可以順利頂(ding)進(jin)，頂(ding)管(guan)施(shi)工報價，降低施(shi)工難度，縮短施(shi)工時間(jian)，保證工程順利進(jin)行。

非(fei)開挖頂(ding)管(guan)施(shi)工(gong)導向孔(kong)(kong)(kong)施(shi)工(gong)完畢后(hou)，卸下導向鉆(zhan)頭(tou)(tou)，接上擠密式擴(kuo)孔(kong)(kong)(kong)鉆(zhan)頭(tou)(tou)、分動(dong)器、鉆(zhan)桿(gan)進(jin)行逐級擴(kuo)孔(kong)(kong)(kong)。頂(ding)管(guan)施(shi)工(gong)擴(kuo)孔(kong)(kong)(kong)時(shi)要(yao)根據實(shi)際(ji)情況調整(zheng)擴(kuo)孔(kong)(kong)(kong)等(deng)級及(ji)次數，從現場開挖斷面(mian)進(jin)行土(tu)質剖析，該地層(ceng)為含有較高(gao)石英顆粒的紅壤層(ceng)，這樣，咱們(men)按每立方水參(can)加50kg膨潤土(tu)制造泥(ni)漿(jiang)資料，在擴(kuo)孔(kong)(kong)(kong)過程中(zhong)循環注入，市(shi)政頂(ding)管(guan)施(shi)工(gong)，保(bao)持(chi)鉆(zhan)孔(kong)(kong)(kong)穩(wen)定，而且用DN380mm鉆(zhan)頭(tou)(tou)擴(kuo)孔(kong)(kong)(kong)完成后(hou)，如(ru)鉆(zhan)頭(tou)(tou)扭矩小于2000N.M，便可拉管(guan)，不然，需重復擴(kuo)孔(kong)(kong)(kong)，以保(bao)證管(guan)道回拖(tuo)順利。

本公(gong)司跟您一(yi)起分享非開(kai)挖頂(ding)管(guan)施工應注意的(de)問題有哪些？

頂管工(gong)(gong)程施工(gong)(gong)過程中，施工(gong)(gong)單位(wei)應隨時留意氣候變(bian)化，提前搭好(hao)帳子(zi)，并將準備好(hao)的泥漿放在帳子(zi)內，盡(jin)量減少雨水的稀釋。頂管施工(gong)(gong)施工(gong)(gong)現場的安置和運(yun)用的電(dian)纜也應有(you)專人看管，確(que)保雨天不發生漏電(dian)和觸電(dian)事端。

因此，從事(shi)(shi)非(fei)開挖頂管施工(gong)的(de)工(gong)人，應事(shi)(shi)先準(zhun)備滿足的(de)霍香(xiang)正氣水(shui)或等防(fang)暑藥品。一旦(dan)感到不適(shi)，應立(li)即服藥，以免中暑形成更嚴重的(de)結果。

在室外(wai)進行頂管(guan)工(gong)程施(shi)(shi)工(gong)時，頂管(guan)施(shi)(shi)工(gong)工(gong)人應(ying)(ying)留意避開高(gao)溫(wen)期，特別是正(zheng)午，白天(tian)溫(wen)度(du)高(gao)，光(guang)線強(qiang)。這段時間不適合(he)非開挖(wa)頂管(guan)施(shi)(shi)工(gong)。工(gong)人應(ying)(ying)在涼快(kuai)、低溫(wen)的當地歇息，以確保(bao)下午有滿足(zu)的精力進行施(shi)(shi)工(gong)。

公司從(cong)事非開挖施工、頂管(guan)施工，如(ru)果需要(yao)請撥打電話聯系我(wo)們(men)。

本公司跟(gen)您一起分享(xiang)以下內容(rong)：

關于頂管施(shi)工的(de)突出特點(dian)是什么？

頂管施(shi)(shi)工根據(ju)不同(tong)的地質條(tiao)(tiao)件、施(shi)(shi)工條(tiao)(tiao)件和(he)設計要求，選擇(ze)頂管施(shi)(shi)工方法以及如(ru)何正確選擇(ze)頂管掘進機和(he)配(pei)套輔助設備至關重要。

頂管施(shi)工(gong)是繼盾構施(shi)工(gong)后發展起來的地(di)下(xia)管線施(shi)工(gong)方(fang)法(fa)。頂管施(shi)工(gong)不需要開(kai)挖表(biao)層(ceng)，可以穿(chuan)越公(gong)路(lu)、鐵(tie)路(lu)、河流、地(di)面建筑(zhu)、地(di)下(xia)構筑(zhu)物和各種(zhong)地(di)下(xia)管線。

頂管(guan)施(shi)工(gong)(gong)時，借助于(yu)主頂進(jin)(jin)油缸和管(guan)道間中繼室的(de)推(tui)(tui)力，將工(gong)(gong)具管(guan)或掘進(jin)(jin)機(ji)從工(gong)(gong)作井穿過土層推(tui)(tui)到接收井進(jin)(jin)行(xing)提升。同時，將跟隨工(gong)(gong)具管(guan)或掘進(jin)(jin)機(ji)的(de)管(guan)道埋設在兩口(kou)井之間，以實現不開挖鋪設地下(xia)管(guan)道的(de)施(shi)工(gong)(gong)方法。

人工(gong)(gong)(gong)頂管(guan)施工(gong)(gong)(gong)依靠主頂進油(you)缸、管(guan)道(dao)室(shi)、中(zhong)繼室(shi)等的推(tui)力。采用人工(gong)(gong)(gong)開挖，將工(gong)(gong)(gong)具(ju)管(guan)或掘(jue)(jue)進機(ji)從工(gong)(gong)(gong)作(zuo)井穿過土層推(tui)到接收井提升的方法(fa)。同時，將跟隨工(gong)(gong)(gong)具(ju)管(guan)或掘(jue)(jue)進機(ji)的管(guan)道(dao)埋設在兩口井之(zhi)間，以實現不開挖鋪設地下管(guan)道(dao)的施工(gong)(gong)(gong)方法(fa)。

組織施(shi)(shi)工(gong)(gong)人員認真學習施(shi)(shi)工(gong)(gong)技(ji)術(shu)文件，了解施(shi)(shi)工(gong)(gong)范(fan)圍、地形、地貌、地址(zhi)水文條(tiao)件及沿線各(ge)種原有設施(shi)(shi)。掌(zhang)握施(shi)(shi)工(gong)(gong)工(gong)(gong)期、頂管(guan)施(shi)(shi)工(gong)(gong)技(ji)術(shu)規范(fan)、質量標準和要求、安 全措(cuo)施(shi)(shi)等。并向施(shi)(shi)工(gong)(gong)隊(dui)進行頂管(guan)施(shi)(shi)工(gong)(gong)的技(ji)術(shu)交底(di)。
