Abstract:
A pipe pier system comprising a plurality of pipe pier sections and at least one pipe connecting insert member, said pipe sections being adapted to be butted end to end to each other in linear arrangement, said at least one pipe connecting insert member being adapted to be placed within and connected to respective ends of said butted pipe sections, each of said pipe sections having apertures capable of being aligned with apertures in said at least one insert member for receiving a connector therebetween, a disposition of each said respective apertures of said pipe sections and said at least one insert member being such that said connector is capable of being spanned across said pipe section and said at least one insert member through said respective apertures, said apertures in said at least one insert member having a slot shape such that their dimension in an orientation running with a length of said at least one insert member is longer than a dimension of said apertures in said pipe sections running with a length of said pipe sections, whereby a shearing force on said connector is avoided.
