“王者伽罗腿法熟练”西密山隧道贯王者伽罗腿法熟练通 安来高速全线通车又进一步

  中新王者伽罗腿法熟练网11月2日电(记者 张尼)王者伽罗腿法熟练11月1日,由湖北交投集团投资、中铁二十四局集团承建的安来高速公路渝鄂界至建始段重点控制性工程——西密山隧道顺利贯通,这也为安来高速公路全线通车奠定了坚实的基础。

  安康至来凤高速公路是我国“八纵八横”高速公路网重要组成部分,起点位于陕西省安康市,终点位于湖北省来凤县,线路全长446.26公里,经陕西、重庆、湖北3省市,共分为9段分别进行建设。

  近几年来,陕西、重庆境内相对平缓路段相继建成通车,唯有巫山、巫峡段停滞不前,渝鄂界至建始段(以下简称建始北项目)成为446公里的安来高速最后的断点。啃下这块“硬骨头”就可以撬动全国大交通。

  此次贯通的西密山隧道位于湖北恩施州建始县长梁镇,为分离式隧道,隧道全长1825米,最大埋深448米,由碎石土、页岩、砂岩组成。隧道施工时存在顺层开挖、穿越溶洞,施工安全风险极高。

  记者了解到,项目团队自进洞施工以来,严格落实智能化、信息化、数字化、规范化、精细化“五化”管理,全过程做到安全质量双管控。根据工程特点及总体施工方案,坚持“物探与钻探相结合”原则,通过SIR4000型地质雷达扫描、湿喷机械手、自动布料衬砌台车、自行式液压栈桥等工装工艺,加强地质灾害监测、预警工作,根据地层情况严控开挖进尺,采用超前管棚注浆加固地层,坚持监控量测资料反馈指导施工等措施顺利穿越了浅埋段、软弱围岩段,并克服了洞口偏压等难题。

  此外,在施工过程中,项目团队通过配备设置扬尘监测系统、自动喷淋系统和洗车池、雾炮机、洒水车、压滤污水处理等环保系统和设备,将施工过程产生的废料泥饼压干外运处理,同时将过滤出的清水循环利用于生产降尘,有效解决了施工用水困难、河道易污染等问题,实现了资源再利用。

  安来高速建成通车后,穿越巫山连通鄂渝,形成纵贯南北的高速公路大通道,将对带动渝北、鄂西地区深度融入长江经济带高质量发展、西部大开发等国家战略,推动鄂西生态文化旅游圈建设等具有重要意义。(完)
