Abstract
A water-bottom rubbles leveling apparatus which includes a main body frame having a plurality of telescopic legs, a first movable frame mounted on the main body frame for movement in the longitudinal direction thereof, and a second movable frame having a plurality of telescopic legs mounted on the first movable frame for movement in the lateral direction of the main body frame. A carrier is mounted on the main body frame for movement in the longitudinal direction of the main body frame. Mounted to the carrier projecting downwardly therefrom are a rake and a leveling roller both for effecting leveling work.

A water-bottom rubbles leveling apparatus, comprising:
- a main body frame having a plurality of telescopic legs mounted thereto;
- a first movable frame mounted on said main body frame for movement in the longitudinal direction of said main body frame;
- a second movable frame mounted on said first movable frame for movement in the lateral direction of said main body frame, said second movable frame having a plurality of telescopic legs mounted thereto;
- means for effecting movement of said first movable frame relative to said main body frame;
- means for effecting movement of said second movable frame relative to said first movable frame;
- means for extending and retracting said telescopic legs of said main body frame and said second movable frame;
- a carrier mounted to said main body frame for movement in the longitudinal direction of said main body frame;
- means for effecting movement of said carrier;
- and
- a rake mounted to said carrier projecting downwardly therefrom.
A method of leveling water-bottom rubbles by using a remote-controlled apparatus which is capable of self-propelling in longitudinal and lateral directions and has a rake and a leveling roller mounted thereto, said method comprising the steps of:
- (a) sinking said apparatus on a water-bottom rubble-mound to be leveled;
- (b) adjusting said apparatus horizontally at a datum level;
- (c) leveling said rubble-mound by moving said rake horizontally in the longitudinal direction of said apparatus;
- (d) moving said leveling roller on the rake-leveled rubble-mound horizontally in the longitudinal direction of said apparatus;
- (e) moving said apparatus back and forth or sideways after completion of the leveling work of the assigned area;
- (f) repeating the above recited steps (c) and (d) for a newly assigned area;
- and
- (g) floating said apparatus above the water after completion of entire leveling of the rubble-mound.
