Abstract:
An interconnecting member for a sand or soil bag comprises a plate having a first side and a second side. There is a plurality of projections on the first side of the plate and a plurality of projections on the second side of the plate. There is also a pair of serrations on the first side of the plate. The serrations each include a plurality of teeth arranged in a row and extending away from the plate in a first direction, and an end tooth at one end of the row which extends away from the plate in a second direction which is opposite of the first direction.
Abstract:
The invention describes a system for creating potable, porous structures for restoring coastline. The invention provides for a bag with multiple longitudinal pockets. The bag is made of porous natural or synthetic mesh material and the pockets are filled with lightweight, porous manufactured aggregate. In a preferred embodiment, the lightweight aggregate used in this invention is produced by thermal fusion of silicate clays in a rotary kiln. In another preferred embodiment, multiple bags are encased in a flexible grid material to for a mat. In another embodiment, the mat can be rolled into a log. The bags, mats, and logs can be placed on shorelines and other location to restore coastline.
Abstract:
A wall-building unit for use in the construction of sandbag-type walls for erosion control, slope stabilization and similar applications comprises an inner bag filled with a fill material and an outer bag extending longitudinally over it so that the bottom of the outer bag is adjacent to and covers the open top edge of the inner bag. The wall-building unit holds more fill material than a conventional sandbag.
Abstract:
A method for constructing a submarine barrier against shock waves such as Tsunami and/or against high sea waves, the barrier being built at an intended location in the sea, is disclosed wherein the method comprises the steps of: -providing at least one cylindrical framework (3, 12, 14, 16) with sidewalls having an empty inner space and a height sufficient to extend from a seafloor (2) to a mean sea level (1) at the intended location, -depositing the at least one cylindrical framework (3, 12, 14, 16) into the sea at the intended location, wherein the at least one cylindrical framework (3, 12, 14, 16) is empty or mainly empty or flooded with seawater and -filling the empty inner space with filling material (10) at the intended location. This method enables an efficient construction of a submarine barrier.
Abstract:
The present invention relates to a foldable barrier structure comprising a compartment bounded by a pair of opposed side walls and a pair of opposed end walls, at least one pair of opposed side or end walls being formed from a flexible, foldable material incorporating a stiffening element and a means for receiving a hinge member which permits folding of a central region of each opposed side or end wail of the at least one pair of side or end walls. Also provided is a multi-compartmental foldable barrier structure comprising a multiplicity of such compartments connected, affixed or adhered to one another end to end, as well as a flood defence barrier comprising a first multi-compartmental foldable barrier structure provided with a continuous length of water impermeable material extending across the individual structures along at least one side of the barrier; a second multi-compartmental foldable barrier structure provided with a continuous length of water impermeable material extending across the individual structures along at least one side of the barrier; and fastening means for fastening the first multi-compartmental foldable barrier structure to the second multi-compartmental foldable barrier structure.
Abstract:
A reinforced earth structure is constructed from several earth-retaining layers. When applying the layers, anchoring elements (5) are fitted between the layers. Cladding elements (6) are attached to these anchoring elements (5), with, preferably, there being adjusting means (7) between the anchoring means (5) and the cladding elements (6) and a cavity (8) preferably having been formed between a cladding element and the anchoring means.
Abstract:
An erosion control system and method wherein a fabric filter bag is embedded with and/or filled with a flocculating polymer and is positioned on a sloping soil surface to dam and pond water flowing thereacross for settling of the particles in the water, and as the ponding water seeps into the bag the colloidal particles will be filtered or agglomerated for settling. The water then passes through and out of the bag and is further subjected to agglomeration and filtering by a skirt of filter material also impregnated with flocculating polymer, said skirt being anchored to the bag or stacked to maintain the position adjacent and downslope from the bag.

Abstract:
A construction element for making retaining walls and erosion control structures comprises a plurality of sandbags connected together by means of a cord. The bags have flexible walls and holes through which the cord extends. The holes can be in various positions on the bags, and various spacings of the bags on the cord can be used. The construction elements can be used to form retaining walls, structures for protecting underwater shoreline areas from erosion, and other structures in the civil engineering field.
