CONSTITUTION:A water lift Well 1 and an inject well 2 are furnished at a certain spacing on a road surface, and a substratum 3 is formed being filled with granular substance by pressure. A water feed main pipe 4, a returning main pipe 5, and a heat radiating pipe 6 with height adjusting frame 7 are laid on this substratum 3, and are coupled by saddle tube 8. A paving material 9 such as concrete is placed over these pipes 4, 5, 6, and thereover the surface layer 13 of asphalt, etc., is formed. A water lift pump 11 at the tip of a water lift pipe in connection with the water feed main pipe 4 is installed in the abovementioned water lift well 1, and an inject pipe 12 in connection with the returning main pipe 5 is inserted in the mentioned inject well 2. When a snow fall sensor senses precipitation, the pump 11 is actuated, and the heat of the well water is radiated at the pipe 6. This ensures good snow melting efficiency with the heat radiating pipe buried precisely, and allows reduction of the running costs.

Description

[Detailed description of the invention]

[Industrial Application Field] This invention relates to a method for constructing a waterless snow removal facility for melting snow falling on roads in snowy and cold regions and also for preventing road surfaces from freezing. This invention relates to a method for constructing a waterless snow removal facility that can uniformly melt snow falling on the road surface and prevent ice on the road surface by fixing pipes at a predetermined height and burying them in the road surface.

0002

[Prior Art] The conventional construction method for waterless snow removal facilities is to pour the first concrete flatly at a predetermined height on the roadbed, and then fix the heat dissipation pipes on top of it with clasps. After that, a second concrete pour is performed and the heat dissipation pipes are buried in the concrete, or reinforcing bars are placed on the roadbed in a lattice pattern at a predetermined height and the heat dissipation pipes are fixed onto the reinforcing bars using binding wires. Waterless snow removal facilities constructed using this construction method were used to melt the snow falling on the road surface and prevent it from freezing.

0003

[Problems to be Solved by the Invention] However, in the conventional construction method of waterless snow removal facilities, concrete is required to be poured two or more times, and the curing time required for these concrete castings is long, increasing the construction period. It had the disadvantage of being long. In addition, since the heat sink pipes are fixed with binding wires on top of the grid-shaped reinforcing bars set on the roadbed, and then concrete is poured, the grid-like reinforcing bars are deformed by the weight of the concrete, causing the heat sink pipes to sink and change their installation positions. , it was extremely difficult to install the heat dissipation tube flat in a predetermined position due to bending.

[0004] In particular, when burying a heat dissipation tube using a heat pipe, the heat dissipation section (condensation section) of the heat pipe must be installed within the road surface with a certain upward slope. If the heat dissipation section (condensation section) is bent in the middle, heat will not be uniformly transferred to the road surface, resulting in uneven snow removal.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a method for constructing a waterless snow removal facility that is easy to construct by simplifying the construction procedure and is capable of uniformly removing snow from the road surface. The purpose is

[0006]

[Means for Solving the Problems] The present invention provides a method for constructing a waterless snow removal facility to achieve the above object, in which pumping wells and injection wells are drilled deep underground at appropriate intervals above the road surface. a first step of filling and pressurizing granular materials to a predetermined height to create a roadbed, and a second step of laying a water supply main pipe and a return main pipe; and a mount for adjusting the height of the heat dissipation pipe on the roadbed. a third step of installing and fixing a heat dissipation pipe on the mount at a predetermined height and connecting the water supply main pipe and return main pipe to the inlet and outlet of the heat dissipation pipe, respectively, via saddle tubes; , a fourth step of pouring concrete and burying the heat dissipation pipe, the water main pipe and the return main pipe to a predetermined depth, and installing a water pump at the tip of the pumping pipe connected to the water main pipe to pump the water. A fifth step of installing the snowfall detector in the well, and installing an injection pipe at the tip of the return main pipe inside the injection well, and installing a snowfall detector on the ground that issues a signal to start and stop the pump. The method is characterized in that the sixth step and the seventh step of finishing the concrete surface with asphalt, tiles, etc. are carried out in succession.

[Operation] The operation of the present invention with the above configuration will be explained. That is, pumping wells and injection wells are excavated deep underground at appropriate intervals above the road surface, and the roadbed is built by filling and compressing granular materials to a predetermined height, and water mains and return mains are laid. A frame for adjusting the height of the heat radiation pipe is installed on the roadbed, and the heat radiation pipe is installed and fixed at a predetermined height on the base, and the inlet and outlet of the water supply main pipe, the return main pipe, and the heat radiation pipe are fixed. are connected to each other via saddle tubes, and concrete is poured to bury the heat dissipation pipe, water main pipe, and return main pipe at a predetermined depth. A pump is provided and installed in the pumping well, an injection pipe is provided at the tip of the return main pipe and is installed in the pumping well, and a snowfall detector is installed on the ground to issue a signal to start and stop the pump. In order to finish the surface with asphalt, tiles, etc. on the concrete pouring surface, the pump starts operating in response to the snowfall signal generated by the snowfall detector, and pumps warm groundwater from the main water supply pipe to a predetermined location within the road surface. This underground water is sent into heat radiation pipes that are buried and fixed in the ground. Therefore, the heat of this groundwater is evenly transmitted to the road surface and stored, thereby uniformly melting snow falling on the road surface and preventing it from freezing. On the other hand, when the snow removal is completed, the operation of the water pump is automatically stopped by the stop signal issued by the snowfall detector.
