Submarine pipe construction

DETAILED DESCRIPTION I claim: 1.
A large diameter pipe adapted to be submerged in a body of water in substantially a vertical direction, said pipe being constructed of a plurality of sections or segments of parallel hollow tubes or pipes arranged with their axes parallel to the axis of the pipe with the diameter of said tubes or pipes being less than the diameter of said pipe, an expansion sleeve positioned in the lower end of each tube of one section and in the upper end of each tube of the subjacent section for connecting and joining the ends of adjacent tubes, a shear sleeve segment provided on a portion of the external surface of said expansion sleeve, a shear clamp engaging said shear sleeves and tension means engaging said clamps for retaining them in engagement with said shear sleeves.
2.
A large diameter pipe as set forth in claim 1 wherein said shear sleeves are formed with flared end portions that engage a portion of the adjacent tubes or pipes.
3.
A large diameter pipe as set forth in claim 2 wherein the external surface of said shear sleeves are provided with serrated teeth.
4.
A large diameter pipe as set forth in claim 3 wherein said shear clamps are formed with a serrated surface engagable with the serrated surface of said shear sleeves.
5.
A large diameter pipe as set forth in claim 4 wherein a tension band engages said shear clamps for holding said serrated surfaces in engagement while making a continuous alignment joint contemporaneous with maintaining all of said tubes in a continuous circle.
6.
A large diameter pipe as set forth in claim 3 wherein the shear sleeve of one expansion sleeve is offset vertically from an adjacent shear sleeve with the serrated surface of said offset sleeve being inclined with respect to the vertical axis of said expansion sleeve and the horizontal plane of the serrated surface of the adjacent shear sleeve with a shear clamp engaging the serrated surface of said sleeves to maintain a stable alignment of the tubes in said large diameter pipe
