ROAD SURFACE SPRINKLING SNOW-MELTING SYSTEM CONFIGURATION METHOD AND PIPING STRUCTURE AND PIPE MOUNTING MEMBER

摘要

To provide a road surface sprinkling snow-melting system in which a rising branch pipe 2 is branched at a predetermined interval from a PVC water sprinkling pipe 1 embedded in a state covered with concrete 4, and a sprinkler nozzle 3 provided with a jet tip of snow-melting water on a top surface is connected to the branch pipe to expose the jet tip on the road surface, the system preventing the breakage of the branch pipe due to difference in thermal expansion coefficient between the cover concrete 4 and the water sprinkling pipe 1.SOLUTION: A pipe mounting member 5 is mounted on an outer peripheral surface of an appropriate position of a water sprinkling pipe 1 to provide a concrete coupling projection 53 projecting toward the outer peripheral direction of the water sprinkling pipe 1 so as to harden the cover concrete, so that the water sprinkling pipe 1 is made integrated with the cover concrete 4.SELECTED DRAWING: Figure 6
