A method for the forming and the deposition in a selected place of a bulk consisting substantially of loose or lightly cohesive material, such as sand or other ground material, for example for use as the core or base of a dam, quay, a bank reinforcement, a jetty or a breakwater, for filing holes or trenches in the bed of a waterway, or for the packaging and storage of contaminated material. The invention has for its purpose to carry out a method of the type in such manner that it can be performed very inexpensively and quickly, while nonetheless ensuring an excellent durability of the formed bulk, both in the short and the long term. This purpose is achieved according to the invention through a method of the kind stated in the heading, which is characterized in that a tank (1) is provided, a sheet or cloth (9) is laid in that tank, the loose or lightly cohesive material (17) is then poured onto the cloth or sheet until the tank is filled to a desired depth, after which the pouring is stopped, the projecting parts of the cloth or sheet are then jointed together, for instance by sewing, such that a substantially closed bag is formed enveloping the poured material, the tank is then positioned above the chosen place, and the bag filled with poured material is removed from the tank and deposited at the chosen place.
A method for depositing in a selected location a bulk material consisting substantially of loose or lightly cohesive material such as sand or other ground material comprising, providing a tank, placing a sheet of material in said tank, placing loose or lightly cohesive material on said sheet until the tank is filled to a desired depth, connecting portions of said sheet to one another to form a substantially closed envelope around said bulk material, positioning the tank substantially above the location where the bulk material is to be deposited, and then removing the envelope from said tank and depositing the envelope with the bulk material therein at said location.
A method for depositing in a selected location a bulk material consisting substantially of loose or lightly cohesive material such as sand or other ground material comprising, providing a tank having movable portions movable between open and closed positions, initially moving said portions to closed position, providing a flexible supporting means and placing said supporting means in said tank, placing a sheet of material on said supporting means in said tank, placing loose or lightly cohesive material on said sheet until the tank is filled to a desired depth, connecting portions of said sheet to one another to form a substantially closed envelope around said bulk material, positioning the tank substantially above the location where the bulk material is to be deposited, moving said movable portions to open position and adjusting the position of one end of said supporting means to remove the envelope from said tank and lower the envelope to said location, and depositing the envelope with the bulk material therein at said location.
Apparatus for depositing in a selected location a bulk material consisting substantially of loose or lightly cohesive material such as sand or other ground material comprising in combination, an envelope containing bulk material therein, said envelope including a sheet of material, connecting means for connecting portions of said sheet to one another to form a substantially closed envelope surrounding the bulk material therein, a tank supporting said envelope, means for moving said tank into position substantially above a location where bulk material is to be deposited, said tank including means for removing and depositing said envelope from said tank, whereby said envelope with the bulk material therein can be deposited at said location.
