重庆江津至四川合江的江合高速公路上的赵家隧道近日顺利贯通。该隧道虽为分离式双线短隧道,左右洞均仅长406m,但却有其特点:一是小间距,两洞间最小间距为8m;二是浅埋,最小埋深为1.5m;三是多处存在偏压。因此,施工难度大,技术要求高,安全威胁大。该隧道于2006年7月底动工,经过施工单位努力奋战,仅一年多时间,左右双洞近日顺利贯通。由于隧道在施工过程中未发生任何安全和质量等事故,受到了业主和监理单位一致好评。目前隧道正进行内装修,以迎接江合路的胜利通车。
The tunnel between Zhao Jiang and Chongqing Jiangjin to He-He Expressway in Sichuan Province passed smoothly recently. Although the tunnel is a separate two-lane short tunnel, both the left and right holes are only 406m in length, but it has its own characteristics: one is small spacing and the minimum spacing is 8m between two holes; the other is shallow buried with the minimum depth of 1.5m; There are multiple bias. Therefore, construction is difficult, technical requirements, security threats. The tunnel started at the end of July 2006, after construction units work hard, only a year or so, about the smooth passage of the two holes recently. As the tunnel in the construction process did not happen any safety and quality accidents, by the owners and supervision units alike. At present, the tunnel is being renovated to welcome the victory of Jianghe Road.
