Abstract
The disclosure describes, in part, techniques for designing, fabricating and installing structural caps with a core and composite sleeves to be coupled to structural members of a foundation, such as an installed radial array of batter angled micropiles. These structural caps with sleeves are lightweight and, thus, more portable to difficult-access sites. Once at the sites, operators may fixedly couple these caps to the micropiles or other structural members to form a foundation for a structure to be installed at the difficult-access site.
Claims50
A structural cap for anchoring a leg of a tower to a radial array of micropiles, the structural cap comprising;
- a body having a center and a perimeter;
- a mounting member attached to and protruding from the body substantially at the center of the body, the mounting member for receiving the leg of the tower;
- a bearing flange disposed on the perimeter of the body;
- and
- a sleeve configured to couple to the bearing flange and defining a void to:
- (1) receive a portion of one micropile of the radial array of micropiles, and (2) receive a cementitious mixture about the portion of the micropile for fixedly coupling the sleeve to the portion of the micropile, wherein:
- the sleeve includes a plate at an end of the sleeve for fastening the sleeve to the bearing flange, the plate of the sleeve including an aperture disposed substantially proximate to a center of a perimeter of the plate for receiving another portion of the micropile distal to the portion received by the void of the sleeve;
- and
- the bearing flange includes an aperture for also receiving the another portion of the micropile distal to the portion received by the void of the sleeve.
