Device for embedding objects such as continuous pipes into water bottoms

A device for embedding objects such as continuous lengths of pipes on water bottoms, comprising a support frame, a drive track carried by said support frame and engageable with the water bottom to advance said frame along the bottom, pipe drive roller means on said frame spaced laterally of said drive track and including at least one drive roller frictionally engageable with the object to be embedded for advancing said frame therealong as said drive track moves said frame relative to the water bottom, and a bottom trenching device carried on said frame and being engageable in the water bottom to form a trench for the object to be embedded as said frame is advanced along said bottom and said object, said bottom trenching device comprising a ground mill having a rotor with an axis which is inclined in a vertical plane extending in a travel direction with the lower part of the rotor being advanced in the travel direction in respect to the upper part, a supporting arm on said support structure carrying said ground mill so as to position said ground mill outside said supporting structure, said guide roller means being carried on said support structure in alignment with said drive track.

A device for embedding objects such as continuous lengths of pipes on water bottoms, comprising a support frame, a single drive track carried on one side of said support frame and engageable with the water bottom to advance said frame along the bottom, pipe drive roller supporting means supporting the other side of said frame spaced laterally of said drive track and engageable with each side of the object to be embedded and including at least one drive roller frictionally engageable with the object to be embedded for advancing said frame therealong as said drive track moves said frame relative to the water bottom, and a bottom trenching device carried on said frame between said drive track and said drive roller means and being engageable in the water bottom to form a trench for the object to be embedded as said frame is advanced along said bottom and said object.
