Abstract A method of forming structures by deposition from a pulp, comprising placing drainage means at the base portion of the structure to be formed, the drainage means being associated with means for adjusting the rate of water outflow therefrom, depositing pulp directly on the ground above the drainage means so that water in the pulp outflows through the drainage means while solids in the pulp accumulate above the drainage means and form a deposited structure with upper inclined surfaces. The intensity of the outflow of water from the drainage means is controlled in the course of the depositing operation so as to progressively diminish outflow in the direction from the periphery of the structure being deposited toward the central portion thereof.
A method of forming structures by deposition from a pulp, comprising the steps of laying drainage means at the base portion of the structure to be formed, said drainage means being associated with means for adjusting the rate of water outflow therefrom, depositing pulp directly on the ground above the drainage means so that water in the pulp outflows through the drainage means while solids in the pulp accumulate above the drainage means and form a deposited structure with upper inclined surfaces, and controlling the intensity of the outflow of water from said drainage means in the course of the depositing operation to progressively diminish outflow in the direction from the periphery of said structure being deposited toward the central portion thereof, said pulp, as it is being supplied, being distributed over the front of the formation of the inclined surfaces of said structure.
