Title:
ELECTRIC WALKING PILE DRIVER FOR CONSTRUCTING UNDERGROUND RETAINING WALL
Document Type and Number:
WIPO Patent Application WO/2010/101315
Kind Code:
A1
Abstract:
The present invention relates to an electric walking pile driver for constructing an underground retaining wall to reduce manufacturing and construction costs by using a walking hood instead of the movement means of an electric-drive pile driver equipped with a chain excavating device and to prevent noise and smoke pollution due to excavating work by electric power. The electric walking pile driver for constructing an underground retaining wall comprises: a chain excavating device (500) which is driven by electricity, and a laterally movable walking hood (300) and a forward/rearward movable walking hood (400) which are installed opposite each other on the lower part of a pile driver body (200) in order to move. In the electric walking pile driver for constructing an underground retaining wall, the pile driver body (200) is supported from all sides by the laterally movable walking hood (300) oppositely installed and the forward/rearward movable walking hood (400) oppositely installed so as to prevent the movement of the chain excavating device (500), thereby safely and rapidly enabling excavation. Also, the electric walking pile driver for constructing an underground retaining wall prevents environmental pollution such as noise pollution and smoke pollution due to existing drive methods of an engine by driving the chain excavating device with electricity.
