A steel cap 7 for structurally connecting together a new foundation and an existing tower is disclosed. The new foundation includes at least one foundation element 9 positioned in the ground. The existing tower includes an existing foundation 5 and a tower structure 3 extending from and supported by the existing foundation. The steel cap comprises (a) a first element 11 for connecting the cap to the new foundation element or foundation elements and (b) a second element 13 for connecting the cap to the existing tower and thereby, in use, connecting together the new foundation and the existing tower.

A collection tank for mounting under a floor of a building for collecting water from an area under the floor comprises upper and lower tank portions removably securable by rotatable mating of tabs in cavities. Additionally, a pump platform of the tank is formed by a plurality of ridges which form therebetween a channel so that the water is collectable in the tank between the ridges. Furthermore, the upper and lower tank portions are separable, and a width of the top of the upper tank portion is smaller than a width of the open top of the lower tank portion such that the upper tank portion can be received in the lower tank portion in an inverted orientation, in which the collection tank is inoperable for collecting the water, so as to decrease a height of the collection tank.

The invention relates to a pile upending system for upending a pile such as a monopile for the foundation of offshore wind turbines, the pile upending system comprising; a pivotally mounted pile support frame having a seat for engaging an outside wall of a pile, the pile support frame being pivotable around a support frame axis of rotation for allowing the seat to support the pile during upending, a cable system for supporting an, in use outboard, end of a pile, comprising one or more tensioned or tensionable cables having an outboard end provided with a hoisting member for supporting the outboard end of the pile during upending of said pile, an outboard support system comprising a frame member for, in use, extending outboard and supporting the hoisting member of the cable system,
wherein the outboard support system is arranged with respect to the pile support frame such that the frame member extends transverse with respect to the support frame axis of rotation for arranging the hoisting member at a distance from the seat and aligned with the seat such that a pile may engage the hoisting member upon longitudinal movement of the pile along the seat.

A hybrid foundation structure includes a first perforation hole formed in the ground, at least one second perforation hole formed adjacent to the first perforation hole on a side surface of the first perforation hole, and a first pile and a second pile formed by mixing and injecting soil and soil solidifying agent into the first perforation hole and the second perforation hole.

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 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.
