Abstract
A device for embedding objects such as continuous pipes into water bottoms comprises a support frame which is movable along the bottom on a drive track which is carried adjacent one side thereof. The support frame also carries a plurality of guide and drive rollers which are engageable with the object to be embedded and which engage the object to move the support frame along the object as the drive track advances along the water bottom. A bottom trenching device in the form of a ground mill with a rotatable cutting head is pivotally mounted on a support between the drive rollers and the drive track and it operates on the bottom to remove material therefrom to form a trench. The material may be subsequently directed backwardly over the object to be embedded after it is positioned in the trench.
