| Outline of Final Research Achievements |
Nature-friendly canal walls that combine a timber pile foundation with fieldstone walls were built in Ogata-village, Akita. The timber piles, which provide a foundation, were 4 m long and 160 mm in diameter. First, the piles were driven into the bottom of the canal at intervals of 800 to 1000 mm, after which horizontal members were connected to the top of the timber piles using steel pins. This nature-friendly canal wall construction method, combining timber pile foundations and fieldstone walls is economical in comparison with the conventional method using steel sheet piles and concrete blocks. Furthermore, this method produces an attractive result. The safety of the canal wall construction method proposed in this study was demonstrated by a loading test after construction, as well as the results of monitoring of the behavior of the timber piles and fieldstone.
