RUBBLE LEVELER

摘要

PURPOSE:To easily and uniformly finish up rubble-mound of the seabed even in large water depths by a method in which the surface of rubble-mound is scanned to measure the highest raised up place and its amount and leveling operations for the rubble-mound are repeated. CONSTITUTION:A platform is set on a rubble-mound 6 by spuds 23, and the trolleys 17 and 19 of a sensor B are run to locate places where projected amounts are greatest. The informations of the places and raised up amounts are sent to the trolleys 10 and 13. The trolleys 10 and 13 are moved to the places and a weight A is dropped to strike the rubble-mound 6. The projected portions are degraded by the striking and the surface condition of the rubble- mound is changed. When repeating the detection of the projected portions and the striking of the rubble-mound thereafter, even rubble-mound 6 charged to the seabed in large water depth can be easily leveled to uniformly finished state.
