The present invention relates to the field of construction of underground buildings, specifically to an inverse construction method for a deep, large and long pit assembling structure of a suspension-type envelope enclosure. A method includes design and calculation; engineering construction of foundation piles; control over underground water; construction of a pit enclosure; building of a basement reinforcing and anti-seeping layer; inverse construction; and floor structure construction. By the inverse construction method for a deep, large and long pit assembling structure of a suspension-type envelope enclosure of the present invention, the pit construction quality is easily controlled, the basement is well waterproofed and easily monitored, and the quality control, service and maintenance are easy.

A device for forming, reinforcing, joint sealing and edge protecting of a concrete slab panel, wherein the concrete slab panel having a volume, a length, a width, and a surface. The device comprising of an elongated post having a body, a top end and a bottom end with a plurality of elongated grooves extending along the body; a mounting frame has a length, a width and a thickness. The mounting frames having a connecting means to connect the mounting frame to the posts. The present invention eliminates the needs for saw-cut lines for crack inducement and acts as a joint sealer for the concrete slab to relieve the tensile stresses.

A system for positioning and anchoring columns. The system includes a positioning template having a first frame configured to support horizontal panels, jacking mechanisms for leveling the horizontal panels, a first opening defined by the horizontally aligned panels configured to guide a sleeve when driven downward below grade level through the first opening, and a tubular sleeve for passing through the first opening and for receiving a second frame. The second frame includes frame members defining a second opening on each end of the second frame and a plurality of elongated bars spanning between the first end and the second end. The second frame is for guiding a pile when driven downward. A pile having a first end and an opposing second end is configured for receiving a connecting tube of a column. A column having a connecting tube is to inserted into the pile's first end.

A system for installing an array of pilings for an array of solar panels is highly accurate and efficient. The system includes a horizontal laser and a rotating vertical laser that are mounted on a first piling and aligned with a target on a second piling on the opposite side of the array. An alignment template is placed against a piling and aligned with the vertical rotating laser. The aligned template provides a designated location where the next piling is driven. A hammer target on the pile driver allows the installer to precisely install the next piling. After installation, the next piling is measured for accuracy and if errors are found, an alignment bracket is used to correct the error. The process is repeated until the array of pilings is complete.

A reinforced concrete structure including a reinforcement made from a plurality of elongate longitudinal members of fibreglass or like material, disposed substantially parallel with one another in at least one predetermined direction. The elongate longitudinal members are coupled to one another by means of coupling members of fibreglass or formed by a strip of flexible polymer material. Metal and/or synthetic fibres are mixed with the concrete matrix to provide the structure with shear strength, making it possible substantially to reduce the number of coupling members.
