近(jin)日，廣東省重(zhong)點(dian)工程(cheng)(cheng)——明珠灣大橋(qiao)環市(shi)大道立交(jiao)工程(cheng)(cheng)已經吹(chui)響了全面施(shi)工的號角，明珠灣大橋(qiao)工程(cheng)(cheng)已進入全面沖刺(ci)階段。在(zai)施(shi)工現場，兩臺中(zhong)聯重(zhong)科樁工設備正密切配合(he)，忙碌在(zai)一線，為工程(cheng)(cheng)的順利進行提供助力(li)。

據介紹，環(huan)(huan)市大(da)道(dao)(dao)立交(jiao)(jiao)是廣東省重點(dian)工(gong)程(cheng)——廣州明珠(zhu)灣(wan)(wan)大(da)橋工(gong)程(cheng)項目的(de)(de)(de)一部分，是連接(jie)明珠(zhu)灣(wan)(wan)大(da)橋和(he)環(huan)(huan)市大(da)道(dao)(dao)的(de)(de)(de)重要節點(dian)，竣工(gong)后將直接(jie)連通(tong)明珠(zhu)灣(wan)(wan)大(da)橋和(he)環(huan)(huan)市大(da)道(dao)(dao)，進(jin)一步優化交(jiao)(jiao)通(tong)狀況。“環(huan)(huan)市大(da)道(dao)(dao)立交(jiao)(jiao)工(gong)程(cheng)位置現狀為(wei)十字路口，其(qi)中環(huan)(huan)市大(da)道(dao)(dao)為(wei)城市主(zhu)干路，與港(gang)前大(da)道(dao)(dao)共同組成(cheng)了(le)環(huan)(huan)繞南(nan)沙島(dao)的(de)(de)(de)環(huan)(huan)島(dao)交(jiao)(jiao)通(tong)。既(ji)可以通(tong)過(guo)虎門聯(lian)絡道(dao)(dao)連通(tong)莞(guan)佛高速，又能接(jie)入環(huan)(huan)市大(da)道(dao)(dao)，連通(tong)蕉門河中心(xin)區(qu)區(qu)塊、南(nan)沙灣(wan)(wan)區(qu)塊、明珠(zhu)灣(wan)(wan)起(qi)步區(qu)區(qu)塊，極(ji)大(da)地減少來往連接(jie)各地的(de)(de)(de)交(jiao)(jiao)通(tong)時間成(cheng)本。”施工(gong)現場相關(guan)負責人表示。

他還介(jie)紹道：“環市立(li)交(jiao)(jiao)涉及施工(gong)內容多，需克服立(li)交(jiao)(jiao)橋梁基礎緊(jin)鄰營運地(di)(di)鐵(tie)(tie)、臨近南(nan)沙小學校、交(jiao)(jiao)通繁忙、管(guan)線(xian)復雜等諸多難題，并且該(gai)交(jiao)(jiao)叉口下地(di)(di)鐵(tie)(tie)四號線(xian)南(nan)延線(xian)塘坑(keng)地(di)(di)鐵(tie)(tie)站已開通運營。為確保地(di)(di)鐵(tie)(tie)安全(quan)和(he)降(jiang)低對周邊(bian)的影響，我們多次研究施工(gong)方(fang)案，最終確定采用(yong)中聯重科全(quan)回(hui)轉鉆機ZRT210H和(he)旋(xuan)挖鉆機ZR420相(xiang)互(hu)配合，進行全(quan)套管(guan)全(quan)回(hui)轉鉆機工(gong)藝施工(gong)。”

這種施工方(fang)式主要是(shi)利(li)用(yong)(yong)全回轉(zhuan)(zhuan)鉆(zhan)機(ji)(ji)ZRT210H搭載(zai)的(de)裝置進(jin)行(xing)鋼套管(guan)的(de)回轉(zhuan)(zhuan)與下壓起拔(ba)動作(zuo)，并保證(zheng)鉆(zhan)機(ji)(ji)水平及鋼套管(guan)垂(chui)直精度。同(tong)時(shi)，在施工時(shi)邊(bian)回轉(zhuan)(zhuan)邊(bian)下壓，利(li)用(yong)(yong)沖(chong)抓斗、多頭抓爪以及旋挖鉆(zhan)機(ji)(ji)等(deng)進(jin)行(xing)鋼套管(guan)內部取(qu)土(tu)作(zuo)業，這不僅可以大(da)大(da)減小鋼套管(guan)回轉(zhuan)(zhuan)下壓動作(zuo)時(shi)的(de)摩擦阻力，還能(neng)大(da)大(da)提高施工效率。

“中(zhong)聯(lian)(lian)(lian)重(zhong)(zhong)科(ke)的(de)鉆機性能強大(da)，施(shi)工(gong)(gong)(gong)精度也很(hen)高，施(shi)工(gong)(gong)(gong)質(zhi)量有保障！”現場(chang)操(cao)作(zuo)機手表示。值得一提的(de)是，此項目(mu)工(gong)(gong)(gong)程(cheng)(cheng)恰逢中(zhong)聯(lian)(lian)(lian)重(zhong)(zhong)科(ke)全(quan)(quan)回(hui)轉(zhuan)全(quan)(quan)國免費巡檢活動，中(zhong)聯(lian)(lian)(lian)重(zhong)(zhong)科(ke)服務工(gong)(gong)(gong)程(cheng)(cheng)師對(dui)設備進行了現場(chang)檢測(ce)，并針對(dui)全(quan)(quan)套(tao)管全(quan)(quan)回(hui)轉(zhuan)鉆機施(shi)工(gong)(gong)(gong)、橋梁灌注樁工(gong)(gong)(gong)法(fa)做指導(dao)講解，盡心(xin)盡責掃除隱患，為明珠灣大(da)橋環市(shi)大(da)道立(li)交(jiao)工(gong)(gong)(gong)程(cheng)(cheng)項目(mu)保駕護航(hang)。
