摘要： PROBLEM TO BE SOLVED: To obtain a buried snow-depth sensor by which a snow depth can be detected definitely even when a sherbet layer is generated at the lower-layer part of the snow depth. SOLUTION: A sensor is constituted in such a way that the flat surface of a translucent light-transmitting material is buried and installed so as to be nearly flush with a road surface and that a projector 4 and a photodetector 5 in which a light-projecting part and a light-receiving part are directed upward are installed side by side in parts which are lower than the surface of the light- transmitting material. At this time, the projector 4 and the photodetector 5 are set in positions in which the height Hp of a reflection position in which the light-receiving level of the photodetector 5 due to reflected light becomes higher than the surface of the light-transmitting material is situated when light which is emitted from the projector 4 is reflected diffusely at the upper part.

摘要： PURPOSE: To surely make a snow cover detection sensor function and perform effective snowmelt without losing the function and fine view of road by burying the snow cover detection sensor in a road shoulder stone composed of an amplifier built-in type dispersion reflection type photoelectric switch. CONSTITUTION: The snow cover detection sensor is an amplifier built-in type dispersion reflection photoelectric switch, and its sensitivity is adjusted so that it does not detect a black system of a part on a road but detect a white system, and is incorporated in a road shoulder stone. In other words, a light emitting and receiving element which is a main part of photoelectric switch is housed in a protection socket for the photoelectric switch attaching optical material, and buried in the road shoulder stone. The road shoulder stone housing such constituted sensor is set on the boundary of a roadway and a sidewalk, and snow accumulated on the roadway is detected. When the road shoulder stone type snow cover sensor detects that accumulated snow on the side of the roadway reaches a specified height, energy given to a heat generating wire buried in a paved bed or a heat generating body such as a hot water pipe is controlled, and a heating facility can be operated effectively.

摘要： PURPOSE: To heighten the melting efficiency of fallen snow, by a method wherein a heat-generating wire is arranged in zigzag shape and a heat-generating unit in which a range with a small pitch of zigzagging and a range with the large pitch thereof are alternately arranged is embedded under the surface of a road. CONSTITUTION: In an installation for melting fallen snow on a road, in which installation a heat-generating unit formed by arranging a heat-generating wire 3 is embedded under the surface of the road, an electric current is applied to the heat-generating wire 3, and the fallen snow is allowed to melt, the heat-generating wire 3 is arranged in zigzag shape, and a range 4 in which the pitch of a zigzag is small and a range 5 in which the pitch thereof is large are alternately arranged. In the range 4, a heating value per unit area is relatively large and the fallen snow is allowed to melt completely. On the other hand, although a heating value per unit area is relatively small in the range 5, heat from the range 4 with the small pitch of zigzagging diffuses in the range 5. Therefore, the fallen snow becomes in the state of half-melting, is leveled down by pressure owing to the passage of vehicles, and is allowed to melt advantageously. In this way, the fallen snow at a wider area can be allowed to melt with the same capacity of a power equipment, and the melting efficiency of the fallen snow can be heightened.

摘要： PURPOSE:To operate a snow cover sensor without spoiling the function and the appearance of a road and surely by a method wherein the detection part of the snow cover sensor composed of a diffusion-type photoelectric sensor using a photoelectric switch is buried and installed in the road so as to be exposed on the surface of the road and reflected light from snow accumulated on the sensor is detected. CONSTITUTION:In a snow cover sensor 1, a diffusion-reflection-type photoelectric sensor 2 is protected, at its detection part, by an optical material 3 whose light-transmitting degree is high, it is buried in an interlocking block 4 whose material is the same as a paving material for a road. The snow cover sensor forms the same plane and is constituted as a paving material unit. The snow cover sensor 1 is used after it has been connected to a road heating apparatus provided with heat-generating sources B and to a power supply via a cable protective tube 5. The photoelectric sensor 2 uses a photoelectric switch, e.g. a small-sized cylinder photoelectric switch. Since reflected light from snow accumulated on the sensor 1 is detected, the operation of the sensor is not obstructed by covered snow and the sensor is operated surely.

摘要： PURPOSE:To smooth the falling of snow in a tank by self-weight of the snow by providing a constriction to a snow throwing port of the upper part of the snow-melting tank equipped with a heater to the bottom thereof to make small a throwing area, and preventing thrown snow from adhering to the internal wall of the tank. CONSTITUTION:A constriction 8 is provided to the upper part of circumferential wall of a snow-melting tank 2, and the area of a snow-throwing port makes smaller than the inside area of the snow-melting tank 2. Snow is thrown into the tank 2 through a grating 9 provided to an upper opening of the tank 2, thrown snow is heated by a heater 5 on the bottom thereof to change it into water, and snow into the tank 2 is subsequently lowered by self-weight of the snow. After the snow in the tank is melted, it is detected by a sensor 7, and power to the heater 5 is disconnected. Melt water is drained. According to the constitution, snow is not made to adhere to the inside wall of the tank, and the falling of snow can be made smoothly.
