摘　　要：针对耒宜高速公路中央分隔带横向排水不畅,雨季容易造成路面大面积积水、危及行车安全的问题,根据道路的结构特点,利用水平定向钻进技术无须开挖道路路面、不影响通车的优势,提出采用水平定向钻进技术。同时,配合泥浆技术与注浆技术解决了施工过程中扩孔困难、路基下沉等可能遇到的施工难题。经过现场试验,达到了非常理想的排水效果。为类似排水改造工程提供了解决思路。For these problems of Leiyang-Yizhang Freeway that central separation belt lateral drainage is not smooth,the rainy season is easy to cause a large area of water on the road,endangering traffic safety,according to structural characteristics of the road,the horizontal directional drilling technology does not need to dig the road surface without effect on traffic,and the horizontal directional drilling technology is proposed.At the same time,cooperating with mud and grouting techniques can solve construction problems of difficult hole expanding,roadbed sinking,etc.Through the field test,ideal drainage effect has been achieved,and the results provide a solution for similar drainage reconstruction projects.
