Stakes that has installed in the traditional bridges like Uji-bridge and Togetsu-bridge, have long been used to prevent the stricture of bridges. However, stakes design codes are not established. And little is known about the function of these stakes. In this paper, we focus on the function and performance of stake, and we demonstrate a fundamental experiment. It was found that driftwood passes between piers after rotation about the stake. Consequently, it is approached that stakes should be installed at bridges to divert both driftwood and protect the bridge.
