FUNDATION GRAVEL SINKING APPARATUS OF SEA-BOTTOM FOR HARBOR FABRIC CONSTRUCTION

摘要

PURPOSE: A device for sinking a riprap foundation to a sea bottom for constructing a harbor structure is provided to reduce power consumption by tamping foundation riprap through the driving force of a tamping plate. CONSTITUTION: A device for sinking a riprap foundation to a sea bottom for constructing a harbor structure comprises a work vessel, a tamping cylinder, a drive plate(30), a ring-shaped tamping plate(40), and a tamping guide plate(50), and an underwater camera. The tamping cylinder is vertically positioned at the work vessel and ascends and descends the drive plate. The drive plate is installed inside the tamping guide plate and is driven by the tamping cylinder. The tamping plate tamps a riprap foundation. The tamping guide pipe guides the tamping motion of the tamping plate. The underwater camera is installed in the edge of the tamping guide plate.
