Abstract
A pipe pier system for use in supporting foundations is provided. The pier system is comprised of a plurality of pipe pier sections and pipe connecting insert members. The pipe sections are adapted to be butted end to end to each other in linear arrangement with the pipe connecting insert member being placed within and connected to respective ends of the butted pipe sections. The pipe sections and insert member have aligning holes to allow for a pin to span their diameters for a stable connection. A removable guide cap is provided for the terminal end of the pier assembly to reduce friction as the pier is driven into the ground.
