Abstract

The purpose of this study is to develop a new earth reinforcement technology using spiral bladed drain pipes called "The SDPR" for practical use. The SDPR has both functions of an earth reinforcement to increase a pulling resistance with the spiral shape blades and a drainage pipe to lower a ground water level in the embankment. This paper summarizes the results of the pull-out test and the exposure test for the expressway embankment with inserted SDPRs. The pull-out test confirms that the friction resistance between the SDPR and ground can be provided for the stability design of the embankment with SDPRs. The exposure test confirms the effectiveness of the corrosion prevention by the soil constituent analysis and the microscopic observation.
