| 摘要 |
The invention relates to a hydraulic guillotine including a blade and a method of cutting reinforced concrete piles at grade. The blade is a metal plate having a beveled cutting edge extending across most of one edge, bordered by unbeveled side portions, adapted to slide in channels. The blade may be demountable from a pusher plate, which enables the blade to be changed. The hydraulic guillotine comprises a rear plate adapted to hold one or two hydraulic cylinders to actuate the pusher plate. Two hydraulic cylinders are preferred, because they have less tendency to jam the blade, during use. An anvil or stop extends across the outer ends of the channels, and is preferably removable. The rear plate is preferably mountable on a construction vehicle boom, which allows leveling and raising and lowering the cutter. Methods of cutting using the device are described.
