9月5日，卡马拉尼(ni)甘大桥成功完成20#主墩首(shou)个(ge)悬浇梁段(duan)的浇筑，项目建设(she)再(zai)次踏(ta)出坚(jian)实(shi)一(yi)步。

卡马拉尼甘大(da)桥悬浇(jiao)箱梁采(cai)用(yong)挂篮(lan)施(shi)工，本次浇(jiao)筑(zhu)为2#梁段，其(qi)长度(du)3.5m，采(cai)用(yong)斜(xie)腹板(ban)式的单(dan)(dan)箱单(dan)(dan)室(shi)箱梁，箱梁顶板(ban)宽度(du)13.42m，梁高4.179m，单(dan)(dan)次浇(jiao)筑(zhu)方量104.8m3，单(dan)(dan)侧重达131T。

由于项(xiang)(xiang)目采用直(zhi)营自管模(mo)式，挂(gua)(gua)(gua)篮(lan)施(shi)工(gong)(gong)(gong)属于高风险(xian)工(gong)(gong)(gong)序，项(xiang)(xiang)目仅部分(fen)中方(fang)员工(gong)(gong)(gong)和技术工(gong)(gong)(gong)人(ren)具备挂(gua)(gua)(gua)篮(lan)施(shi)工(gong)(gong)(gong)经验(yan)，众多菲律宾劳工(gong)(gong)(gong)不仅毫(hao)无(wu)施(shi)工(gong)(gong)(gong)经验(yan)，甚(shen)至(zhi)从未见过(guo)挂(gua)(gua)(gua)篮(lan)。为保证挂(gua)(gua)(gua)篮(lan)悬浇(jiao)(jiao)箱梁施(shi)工(gong)(gong)(gong)的(de)质量(liang)安全可(ke)控，项(xiang)(xiang)目技术管理(li)(li)人(ren)员精心编制施(shi)工(gong)(gong)(gong)方(fang)案，细化三级交底(di)，英文(wen)版交底(di)全覆盖参与挂(gua)(gua)(gua)篮(lan)悬浇(jiao)(jiao)施(shi)工(gong)(gong)(gong)的(de)菲籍工(gong)(gong)(gong)人(ren)，并通过(guo)动画(hua)演示、现场(chang)讲解等多种方(fang)式，向菲籍工(gong)(gong)(gong)程(cheng)师(shi)和现场(chang)工(gong)(gong)(gong)人(ren)强(qiang)调质量(liang)、安全控制要点。在挂(gua)(gua)(gua)篮(lan)安装后(hou)(hou)和混凝土浇(jiao)(jiao)筑前(qian)，项(xiang)(xiang)目管理(li)(li)人(ren)员组(zu)织进行联合检(jian)查(cha)，对挂(gua)(gua)(gua)篮(lan)的(de)后(hou)(hou)锚、吊(diao)杆吊(diao)带(dai)、前(qian)支(zhi)座、主桁连接、模(mo)板(ban)、安全防护、钢筋(jin)、预应力(li)及预埋(mai)件进行逐项(xiang)(xiang)检(jian)查(cha)、整(zheng)改，有力(li)保障首(shou)段(duan)悬浇(jiao)(jiao)箱梁的(de)顺利浇(jiao)(jiao)筑。

下(xia)一步卡马拉(la)尼(ni)甘(gan)大(da)桥主桥的三个主墩(dun)将陆续(xu)进入挂篮悬浇箱梁施(shi)工(gong)阶(jie)段，项目(mu)人员将根据(ju)本次首(shou)件施(shi)工(gong)中遇(yu)到的问题和观测数据(ju)，总结宝(bao)贵施(shi)工(gong)经验，继续(xu)做好大(da)桥建设(she)安(an)全、质量管理(li)，咬定(ding)项目(mu)总工(gong)期目(mu)标，圆满完(wan)成公司首(shou)次“桥品牌(pai)”出海。（长江(jiang)分公司）
