An elongated narrow bulk delivery and depositing bouyant conveyor belt device is operable to shore up bridges, docks and/or piers in environments having operating space confined by low overhead and narrow berths between adjacent spaced apart pilings. The bouyant conveyor belt structure is alternately extendable and retractable in each of shallow and deep water. The bouyant conveyor belt structure is stabilized by one or between two linear axially extending substantially parallel sides of spaced apart floating platform barges. The barge(s) typically mount hopper and vibratable chute structure receivable of bulk typically rip rap fill material and feedable thereof onto the bouyant conveyor belt structure, thereafter deposited by a revolving of the conveyor belt structure.
