Development of “Headroom restriction Clear Piler for ultra-low overhead clearance” and “steel sheet pile mechanical joint”

Development team：
Japan Water Agency, Japan.
East Japan Railway Company, Japan,
TOTETSU KOGYO CO., Japan
GIKEN LTD., Japan

Outline of Innovative Technology and the reason for awarding：
This project made three significant innovations:
(1) Development of an ultra-low overhead clearance silent piler. The headroom has been reduced from a height of 1365mm for a conventional Clear Piler to 1080 mm for the ultra-low headroom piler.
(2) Development of a special steel sheet pile to be fitted from lateral direction by horizontal feed joints in S-shape for the use with the ultra-low headroom piler.
(3) Application of the new equipment to the installation of a sheet pile wall under a bridge. The headroom was extremely small and the water flow velocity was up to 2 m/s.
Considering the significance of the innovations and potential future applications of the technology, this project deserves an Innovative Technology Award.
