Abstract: An earth retention levee system is disclosed which is constructed from spaced apart facing parallel walls of interlocking sheet piles (1, 2) said sheet piles having outside faces (5) and inside faces (4) formed with gridspines (10) along a longitudinal extent thereof, said gridspines (10) being connected to adjacent edges of geogrids (20) which link said parallel walls and stabilise fill (21) disposed therebetween.

Abstract: A metal fin tube foundation includes a pair of coupled metal plates, each plate being comprised of a plurality of flat panels, wherein each panel is positioned at an angle relative to an adjacent panel, and each plate including a fin on each lateral end of each plate, wherein each fin overlaps a fin of the other metal plate forming two pairs of overlapped fins, wherein the plates are coupled along each of the two pairs of overlapped fins; wherein the plurality of panels of the coupled two metal plates form a closed perimeter polygon shape having an open interior and wherein each pair of overlapped fins form a combined fin element which extends away from the perimeter of the polygon.

Abstract: A tsunami breakwater wall of a multilayered steel pipe pile structure 1, includes a multilayered steel pipe pile 2 where a bottom end thereof reaches a predetermined depth of a support layer 28 and is installed to a ground 26 such that an upper end thereof protrudes upward from a ground surface 26a, and a wall body 15 constructed integral with a part of the multilayered steel pipe pile 2 that protrudes upward from the ground surface 26a. The multilayered steel pipe pile 2 is made from a plurality of large diameter steel pipe piles 3-5 of different diameters, an upper end of an inner most side steel pipe pile 3 protrudes upward from the ground surface 26a, and the wall body 15 is constructed to a part of the steel pipe pile 3 protruding upward from the ground surface 26a.

Abstract: An elongated element (1) having a cross-sectional shape permitting the element to be interlocked with adjacent elements, the element having a basic square shape with interlocking members (4,6,8) on at least three sides of the element, wherein the proportions of the element and the interlocking members are such that the elements can be interlocked in side by side and/or overlapping relationship.

Abstract: A concrete retaining wall is disclosed on which flora can be cultured and a method for constructing the same. The retaining wall has a steel skeleton constructed with basal H-beams, aerial H-beams, L-beams, structural steel tubes and steel plates. The basal H-beams and the aerial beams are arranged in a direction parallel with the earth's surface and at a significant angle to the earth's surface, respectively, at such space intervals and dimensions that the retaining wall structure has sufficient bending resistance to overcome active earth pressures. The L-beams, the structural steel tubes and the steel plates are provided as reinforcements between the H-beams. Watertight concrete is applied to the basal H-beams. Wire mesh is attached to the aerial H-beams, the L-beams, the structural tubes and steel plates. The wire-mesh-mounted structure is coated with water-permeable concrete to form a stepped or embossed external surface.

Abstract: A cellular structure, in particular a supporting or sound insulation structure plantable with greenery, one with earth, rock, or bulk material filling (Ed), arranged in particular as cells (Z) in layers, the cells being bounded at least in part by flat flexible, liquid-permeable, and corrosion-resistant material (F), in particular material in the form of netting or a grating, and having at least one dimensionally stable frontal element (FG) also in the form of netting or a grating which is connected to tension bracing (ZA) extending into the cell filling and to support bracing (ZV) ensuring the assigned frontal surface inclination and frontal surface position of the structure, the support bracing (ZV) for the individual front elements having at least one elongated bracing element (AS) which on one side is connected to a front element (FG) and on the other extends into the area of the filler.

Abstract: A subsurface barrier wall having a number of interconnected columns is disclosed. The columns are driven into the subsurface, one next to the other in interlocking fashion, with a percussive drive hammer. A sonic drilling tool is driven ahead of the columns. The columns include interconnecting elements which slidably couple adjacent columns together as a column is being driven into the subsurface. The barrier wall may be used to divert, contain, or remediate the migration of subsurface contaminants.

Abstract: A method for connecting in a liquid-tight manner cooperating lock halves of a locking device of adjacent wall sections of a multi-sectioned wall introduced into a suspension includes providing a first lock half as an inner profiled member and a second lock half as an outer profiled member. The inner profiled member is inserted into the outer profiled member so that the profiled members substantially areally rest at one another and form a capillary gap. An inner groove is cut over the length of the lock halves such that the inner groove extends through the wall of the inner profiled member into the wall of the outer profiled member. The area of the wall of the inner profiled member where the inner groove is located is sealed against the suspension with a sealing material introduced into the gap. The inner and outer profiled members are fused with a fusing material introduced into the inner groove.

Abstract: A foundation for a retaining wall-type of structure acted upon by a principal force tending to slide same in a predetermined direction is anchored by a plurality of slide resisting walls. The slide resisting walls extend parallel to the predetermined direction in which the foundation tends to slide. The upper portions of the slide resisting walls are embedded in a concrete mass. The lower portions of the slide resisting walls project downwardly from the concrete mass into the earth, and are solely in engagement with the earth and not with concrete.
