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.
