风积沙地区高速公路排水设施施工技术

Construction technology of highway drainage facilities in aeolian sand area

我国在沙漠地区已修建了大批的高速公路,沙漠地区高速公路水毁问题的研究以及防治问题一直都是世界上许多国家共同面临的难题。为解决这一问题,通过对榆佳高速风积沙地区出现的多处水毁的调查与分析,得出了风积沙地区公路水毁的原因,根据水毁形成原因,结合现场实际情况,给出了风积沙地区高速公路排水系统优化设计方案及施工方案,很大程度上减小了公路因排水不畅而受损的概率,保证了高速公路的使用寿命。

A large number of highways have been built in the desert area in our country,and the research and prevention of the problem of highway water destruction in the desert area has always been a common problem for many countries in the world.In order to solve this problem,through the investigation and analysis of water damage in the aeolian sand area of Yujia highway,the causes of the highway water damage in the aeolian sand area are obtained.According to the causes of the water damage and the actual situation of the site,the optimal design scheme and construction scheme of the expressway drainage system in the aeolian sand area are given,which greatly reduces the probability of the highway being damaged by the poor drainage and ensures the service life of the highway.
