WATER PIPING DEVICE
Document Type and Number:
Japanese Patent JPH09184165
Kind Code:
A
Abstract:

To make it possible to execute piping work on the water without using any drum and to reduce a construction cost by connecting two pairs of floats with flexible float connection belts, and providing pipe flexible pipe fixing belts for surrounding the outside of a pipe.

Floats 1 are spread on the ground on a state to remain unexpended, and the floats 1 and 1 are developed with flexible center float connection bodies 3 as the center in a bisymmetrical state. Then, one piece of pipe 2 is laid on the central part of both floats 1 and is installed. Then, under such a state, after compressed air is supplied from air supply inlets 11 of the floats 1 to expand the floats 1, they are fastened in a state to surround the outside of the pipe 2 with pipe fixing belts 4. As a result, the pipe 2 is positioned between the floats 1 and 1 on both sides to be expanded and pipe fixed belts 4 and is ensured in such a state. When such work is repeated to mount the floats 1 and 1 to a plurality of pipes 2, the pipes 2 are connected to each other through flanged of the ends of the pipes 2.
