非洲干旱地区砂性土路基洒水焖料和碾压施工工艺

Construction Technology of Water Spraying and Compacting for Sandy Soil Subgrade in Arid Region of Africa

根据塞内加尔机场高速公路项目实施情况,研究了非洲干旱地区砂性土路基施工工艺及常见的质量问题及防范措施,总结了类似项目路基施工难点及解决措施。砂性土料路基工施工,比一般土料路基施工的难度大,施工工艺和施工方法需严格把控。施工过程中需要把握好洒水量和洒水方法,控制好碾压施工,施工质量才能满足要求。

Based on Senegal Airport Expressway Project,this paper studies the construction technology,common quality problems and preventive measures of sandy soil subgrade in arid areas of Africa,and summarizes the construction difficulties and solutions of similar projects.Construction of sandy soil subgrade is more difficult than that of general soil subgrade.Construction technology and method should be strictly controlled.During the construction process,it is necessary to grasp the sprinkler quantity and method and control the rolling construction so that the construction quality can meet the requirements.
