用工匠精神铸就精品工程
2017-09-01 08:21:28 中国青年网
本报讯(记者黄仕强 通讯员文笑一 詹树高)“把工人的士气鼓起来,让青年突击队的旗帜飘起来……”8月底,经中建隧道500多名参建职工4多年的奋战,重庆市郊铁路(重庆轨道延长线)控制性工程缙云山隧道顺利贯通,为全线通车打下了坚实的基础。
隧道贯通的背后,是中建隧道缙云山隧道项目部的一次次攻坚克难。“回顾一路走过来的1500多天,困惑、坚强、快乐,难以释怀。”该项目部生产经理陈宇波对记者说。
缙云山隧道是重庆市郊铁路尖璧段重要节点工程,全长3635米,最大埋深约220米,开挖宽度11~12米,开挖高度9~10米。隧道穿越断层破碎带、石膏岩断面、煤层及饱和粉细沙层、高压地下水区、地热异常区、岩溶发育区、煤矿采空区等,地质复杂,素有“西南地质博物馆”之称。
为了实现工程安全质量管控目标,项目部进场之初就提出了“首件验收、样板引路”的工作思路,执行“一岗双责”,加大巡检力度,始终坚持不蛮干。缙云山隧道特殊的地理环境是施工管控的重点和难点,技术人员采取“反压回填、初支加固后注浆、增设锁脚及系统锚杆”等方法,确保工程的顺利推进。
针对隧道渗漏水等问题,项目部组建专家队伍、技术小组发起攻坚,采用新技术、新工艺、新材料、新设备,研发了“皮肤式防水”新方法,实现了建设单位提出的“三零”(隧道零渗漏、人员零伤亡、环境零投诉)管控目标。
该项目组建以来,先后获得“重庆市青年文明号”“重庆市优秀突击队”“重庆市重点工程劳动竞赛先进班组”“重庆市交通建设工会工人先锋号”“安全文明标准化示范工地”等荣誉10多项。
