PROBLEM TO BE SOLVED: To provide a riprap throwing work supporting device allowing a worker to accurately determine the next throwing position and the next amount of ripraps to be thrown because the worker can predict a shape of piled-up ripraps (a shape of mound) on the sea bottom immediately after throwing ripraps on a computer screen and guide a grab for throwing ripraps to the throwing position on the computer screen to form a target shape of piled-up ripraps (the shape of mound) on the sea bottom efficiently. SOLUTION: This riprap throwing work supporting device is composed of a ship position detection sensor 11, a grab riprap throwing position detection sensor 12, a grab riprap throwing time detection sensor 13, a sea bottom piled-up riprap mound shape inferring means 15 incorporated into a computer 14 to compute and infer the sea bottom piled-up riprap mound shape formed on the ground on the sea bottom after piling up ripraps, and a display unit 16 for displaying the sea bottom piled-up riprap mound shape.
