The Civil Engineering Laboratory has designed an improved mechanical pile splice that requires no in-the-field welding or special crane handling requirements. The splice consists of a friction tube pipe with a smaller diameter that forms a press fit against the internal diameter of the piles to be joined together. Tapered insertion guides at each end of the friction tube aid in inserting the splice and driving it into the piles. A short section of pipe, of the same diameter as the piles to be spliced, is welded to the middle section of the friction tube and acts as a bearing ring for seating against the piles. The splice is designed to separate under normal pile pulling tensile loads using a construction crane. This allows pile removal at or below the mud line, eliminating the need to use shaped charges or other methods of cutting for pile removal. The mechanical splice can be dimensioned to fit any size pipe pile. The thickness and lengths of the splice components can be designed to accommodate strength requirements for bending and compressive loads. Special attachments can be welded to the splice for handling if desired.
