The purpose of this research is to develop a new earth reinforcement technology "The SDPR method" having both functions of a single earth reinforcement to increases the embankment strength and a drainage pipe to lower a ground water level in embankment at the same time. This paper summarizes the field test results of pullout test and drainage test of the SDPR method. The main conclusions are as follows: 1) It is possible to install a SDPR by using a conventional boring machine. 2) It was found that by a pull-out resistance test the SDPR integrates entirely bonded to the surrounding ground and the interface resistance between SDPR and the ground had a very high correlation with the representative N-value of the ground. 3) It was found that by installing SDPR into embankment the hail-life of an effective rainfall to match groundwater fluctuation was shorter meaning that SDPR accelerates water pressure dissipation and drainage from embankment. 4) It was found that ultimate effective rainfall increases to improve drainage resistance of embankment by installing SDPR.
