Document Type and Number:
WIPO Patent Application WO/2012/165461
Kind Code:
A1
Abstract:
[Problem] Provided are: an air discharge pipe structure for melting snow on a road surface, the air discharge pipe structure being configured so that the air discharge pipe structure can more evenly discharge snow melting air into an area underneath the road surface on which the snow to be melted is present than conventional structures to prevent the uneven melting of the snow, so that the air discharge pipe structure can be built more easily, and so that the air discharge pipe structure can be built in a reduced time and at reduced cost; a road surface material for melting snow; and a system for melting snow on a road surface. [Solution] An air discharge pipe structure for melting snow on a road surface is provided with: perforated pipes (7, 7, ...) which have air ejection holes (6) formed therein and which are laid in a predetermined area underneath the road surface (5) on which the snow to be melted is present; a pair of connection pipes (8, 8) for air flow, connecting the opposite ends of each of the perforated pipes (7, 7, ...) in a pneumatically communicable manner; and an air supply pipe (9) which connects one end of each of the connection pipes (8, 8) for air flow in a pneumatically communicable manner and which is provided with an air supply opening (11) for supplying air. The other end (81) of each of the pair of connection pipes (8, 8) for air flow is connected to each other in a closed state or is connected to each other by an end air-flow pipe (10) in a pneumatically communicable manner.
