高速公路改扩建项目临时交通安全设施设置方案探讨

Temporary Traffic Safety Facilities Setting Scheme of Expressway Reconstruction and Extension Project

为了探讨高速公路改扩建项目的临时安全设施设置方案,结合四川省成都市至乐山高速公路改扩建工程项目(以下简称成乐项目)的施工过程及保通要求,分析研究半幅路基封闭施工条件下的临时安全设施设置方案,并对作业区及道路分流引导区的临时安全设施设置方案进行探讨,得到了合理可行的临时交通安全设施设置方案,用以指导高速公路改扩建项目的施工。

In order to discuss the temporary safety facilities setting scheme of expressway reconstruction and expansion project, combining with the construction process and maintenance requirements of Chengdu-Leshan expressway reconstruction and extension project in Sichuan Province(hereinafter referred to as Chengle project), the temporary safety facilities setting scheme under the condition of half roadbed closed construction is analyzed, and the temporary safety facilities setting in the work zone and road diversion guide area is also studied. A reasonable and feasible scheme of temporary traffic safety facilities is obtained to guide the construction of expressway reconstruction and expansion projects.
