Method of building a grid system wherein a plurality of modular apparatuses can be arranged at a structure site. The plurality modular apparatuses can have a central tubular member having an inner bore formed between a proximal end and a distal end, and a plurality of vanes having a lateral width at least equal to a diameter of the central tubular member. The one or more modular apparatuses can be positioned above a surface of the structure site. Each of the plurality modular apparatuses can be connected with at least two adjacent modular apparatuses of the plurality of modular apparatuses via a locking lug on one of the plurality of vanes slidingly engaged with a locking channel on an adjacent modular apparatus. The plurality of modular apparatuses can then be driven into the structure site wherein the inner bore receives earthen formation therein.

The invention relates to a cover for use on public roads, comprising an outer body (2) that houses at least one reinforcement (1). Preferably, said outer body (1) is made of a plastic material, e.g. injected plastic material, and said at least one reinforcement (1) is connected by means of said outer body (2) to form a single piece.

The cover according to the invention is lighter than that conventional covers, given that it is made with less metal and with lighter materials. Moreover, the cover cannot be easily recycled and hence is not at risk of theft.

A cooling tower structure having a concrete perimeter foundation wall with a perimeter rebar grouping. The structure includes at least four columns formed of CMU blocks with at least two columns being freestanding and positioned approximate corners of the foundation wall. Each column further includes a column rebar grouping being tied into the perimeter rebar grouping. At least three bond-beams formed of CMU blocks are connected between the columns at least four feet above the foundation. The bond-beams include beam rebar groupings tying into at least one of the column rebar groupings. The structure includes housing walls formed of CMU blocks extending upward from the bond beams. At least one fan is on at least one pedestal column positioned within the foundation wall, with a pedestal rebar grouping extending though the pedestal column from a concrete pedestal footing. A series of water collection troughs are positioned within the cooling tower above the fan and fill media is positioned in the cooling tower above the collection troughs.

A plant-based construction block (2) for a building element (1), for example a wall. The plant- based construction block (2) comprises a uniform recess (3) extending between two opposite faces (5) of the plant-based construction block (2). The recess comprising first and second interlocking portions (4a, 4b) disposed on opposite sides of the recess (3) such that an interlocking portion of a further identical plant-based construction block can be received in the recess (3) and engage the first interlocking portion (4a), and such that an interlocking portion of a second further identical plant-based construction block can be received in the recess (3) and engage the second interlocking portion (4b).

A method of installing a reusable security barrier is presented that allows quick installation and removal. In one embodiment, the method comprising providing precast concrete panels having a rectangular profile elevation, digging a trench having a length equal to or longer than the panel width, lifting and placing the panel such that a portion of the panel is inserted inside the trench and a portion extends vertically upward from the trench forming a barrier, with a narrow opening between the panels, and filling and packing the trench unfiled by the panels with a filler to provide a solid foundation. The method can comprise utilizing multiple panels placed side edge to side edge with their bottom inserted inside a trench to form a longer barrier. The method can further comprise removing the panels from the trench for reuse in a second site when the original security barrier is no longer needed.
