ABSTRACT:
This invention relates to a method of splicing pile cages, to a set of components therefor, and to assembled pile cages, and in particular to a method of splicing together two pile cages of a reinforced concrete pile. The method employs two pile cages which are each assembled from a number of cage bars and at least one frame, one of the pile cages having a suspension band adjacent to one of its ends, the other pile cage having at least one support plate adjacent to one of its ends, the support plate having a hole therethrough. One of the pile cages is lifted into a pile hole with its end projecting therefrom, and the second pile cage is lifted over the first pile cage and lowered until a part of the cage bars of the second pile cage overlap a part of the cage bars of the first pile cage, and the hole in the support plate lies below the suspension band. A suspension bolt is inserted through the hole in the support plate so that a part of the suspension bolt lies underneath a part of the suspension band, whereby the first and second pile cages can be lifted together with the suspension bolt engaging the suspension band.
