                    义永公路焦山隧道左洞顺利贯通
                    发布时间:2020-01-08   浏览次数:

                    (姜兆)1月8日,义永公路焦山隧道(左洞)顺利贯通,这是义永公路开工建设以来贯通的首条隧道,现场举行了简短而隆重的贯通仪式。

                       焦山隧道位于义乌市赤岸镇三角毛店村附近,为双向六车道分离式隧道。本次贯通的是左洞,自隧道出口(永康端)向进口(义乌端)单头掘进,全长488米,设计时速80公里/小时。该隧道出洞口段围岩体裂隙较发育,岩体呈碎石状松散结构,围岩稳定性差,易发生大坍塌掉块,施工难度较大,是制约整个义永项目进度的关键工程之一。

                       为此,项目部克服重重困难,充分预估风险,周密设计方案,紧绷安全之弦,严格过程控制,确保施工安全和进度。项目组还采用“隧道监控量测”、“隧道超前地质预报”等科技管理手段,首次启用国内先进的湿喷机械手、多臂凿岩机等设备进行隧道作业,降低施工风险,提升施工质量,提高施工效率。

                       目前,义永公路焦山隧道(右洞)、枫坑隧道的施工还在紧张有序地进行着。届时,焦山隧道和枫坑隧道之间将会通过紫溪坑小桥连接,实现全线贯通,直接连通义乌南大门和永康市,促进区域社会经济综合发展。

                    焦山隧道左洞自2019年7月11日开工以来,经过182天日夜不歇的奋战,终于实现大贯通,提前完成了工期目标。这极大地鼓舞了项目的团队士气,也为后续枫坑隧道的施工建设提供了宝贵经验。项目负责人郭飞德表示,新的一年,项目组将继续发扬“善打硬仗、敢于胜利”的正方铁军精神,铆足干劲,紧抓施工,高度重视安全、质量、细化过程控制,力争义永公路早日建成通车。
