高速公路路基边坡及绿化的快速施工

Rapid Construction of Subgrade Slope and Greening of Expressway

随着严守耕地红线与环保意识的不断增强,如何实现路基边坡及绿化的快速施工越来越受到重视。以潍日高速潍坊连接线项目为例,针对不同地质条件,研究土质填方路基边坡及不同岩质挖方路堑边坡快速施工及绿化施工方法。实践证明,对比传统路基边坡施工法,本项目所采用的土质路基边坡模板法可平均降低路基造价0.5万元/km,节约工效1日;不同岩质挖方路堑边坡可通过因地制宜的放坡开挖方式实现边坡的快速施工。在此基础上可实现边坡的快速绿化防护。

With the increasing awareness of environmental protection and observe the red line for arable land strictly,how to realize the rapid construction of roadbed slope and afforestation attracts more and more people's interests.Taking the Weifang connecting line project of Weifang-Rizhao Expressway as an example,according to different geological conditions,this paper explores the rapid construction method of earth-filled subgrade slope and different rock-cut slope,and realizes rapid greening.Practice shows that compared with the traditional roadbed slope construction method,the drawing roadbed slope formwork method adopted in this project can reduce the average cost by 5000 yuan per 1 km roadbed and save 1 day of work efficiency.Different rock cut slopes can be rapidly constructed by means of excavation method according to local conditions.On this basis,rapid greening protection of slope can be realized.
