Claims (1)

[Claims for Utility Model Registration] 1. An inspection groove 2A is formed at the center in the longitudinal direction of the snow melting road surface 2, which is a flat snow melting road surface and is composed of asphalt pavement, and within the inspection groove 2A,
A drainage pipe 2D with a thickness and slope that allows drainage to the sewer or underground reinjection well 2C is installed, and within the snow melting road surface, a snow melting pipe 3 is installed with an appropriate slope that allows the snow melting medium water to naturally flow down and drain. The piping 3 has a location where the inspection groove 2A is installed, and is connected to the drain pipe 2D via the same number of energized closed solenoid valves 4 as the number of rows of the snow melting piping 3, and the energized closed solenoid valves 4 Due to a power outage, the solenoid valve 4 is closed when energized.
is opened and the snow melting medium water naturally flows down and drains, and when the electricity is energized, the closed solenoid valve 4 closes to operate the snow melting circulating water, and the snow melting medium water is circulated and drained to prevent freezing. The waterless snow melting device is characterized in that an air vent 3A is provided at the highest part of the snow melting pipe 3 in order to improve the drainage efficiency. 2. Claim 1: The inspection groove 2A is removably fitted with a dot plate 2B for the purpose of not only grasping the state of circulation of the snow melting medium water but also maintaining the road surface and protecting the solenoid valves and drain pipes. The waterless snow melting device described. 3. The air vent 3A is located in an air vent mounting section 2E provided on the snow melting road surface 2, and an inspection protection lid 2F or the like is removably attached to the air vent mounting section 2E to protect the road surface. 2. The waterless snow melting device according to 2. 4. The above-mentioned inspection groove 2A having an inspection panel 2B so that when the snow melting water loses its circulation power due to a power outage etc. on the snow melting road surface 22 which is a slope, the water flows down naturally to the lower part of the slope and concentrates.
A snow melting pipe 3 is installed in the snow melting road surface 22, and the snow melting pipe 3 is connected to the electromagnetic valve 4 that closes when energized.
A waterless snow melting device characterized in that it is connected to a drain pipe 2D in the inspection groove 2A through. 5 The above-mentioned snow melting pipe 3 is a straight pipe, and garbage,
If snowmelt water cannot circulate due to a blockage due to rust, etc., remove the inspection protection lid 2F and use a long hard cleaning wire such as steel wire to pierce and clean the blockage. The waterless snow melting device according to any one of claims 1 to 4.
