Self-closing sheet for encapsulating and dumping a bulk of material

a self-closing sheet and bulk material technology, applied in special-purpose vessels, soil-shifting machines/dredgers, transportation and packaging, etc., can solve the problems of unusable practical use, adverse long-term effects, and inability to meet the requirements of use, and achieve low material strength, facilitate the degree of inner sheet extension, and reduce the effect of material strength

Abstract

The invention relates to a sheet (1) to be placed in relation to a split barge (100) for encapsulating a bulk of material (101) to be dumped when the bulk of material is released, the sheet comprising a material containing portion (4) and at least one material free portion (3) extending from at least two opposed sides of the material containing portion, wherein that the immersed sheet encapsulating the bulk of material comprises an encapsulated body (20) encapsulated by the material containing (4) portion and a self-closing portion (22) being at least a part of the material free portion (3) both extending from an assembly point (21), wherein a closing length of the self-closing portion (22) correspond to at least 5% of the circumventing length of the encapsulated body (20), the circumventing length extending from the assembly point (21) to the assembly point (21). The invention further relates to a method of encapsulating a bulk of material by means of a sheet.

Description

FIELD OF THE INVENTION

[0001] The invention relates to a sheet to be placed in relation to a split barge for encapsulating a bulk of material to be dumped when the bulk of material is released, the sheet comprising a material containing portion and a material free portion extending from at least two opposed sides of the material containing portion. The invention further relates to a method of encapsulating a bulk of material by means of a sheet.BACKGROUND OF THE INVENTION

[0002] Dredging—the excavation of materials such as sediment of soil, sand, clay, slit and / or rocks from beneath bodies of water such as rivers and oceans—is a large global industry that makes marine construction projects possible, and supplies a large portion of the world's sand consumption.

[0003] The industry reuses a large portion of the 9 billion cubic meter of matter it excavates every year for construction purposes, coastal feeding or landfilling. However not all material is suitable. Somewhere between 22-25% of t...
