[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a snow removal treatment structure capable of easily removing snow removal for which a treatment method is a problem in a snowy area and without incurring the cost for snow melting.

[0002]

[Prior art]

 In snowy areas, the treatment of a large amount of snow removal caused by snow removal becomes a problem every winter. In this case, there is a problem that snow removal must be done on a city road while allowing a large number of cars to pass through smoothly, and there is no place for snow removal at business establishments such as companies and private houses.

For this reason, as a method of removing snow from city roads, large dump trucks are used to transport the snow to a snow dump site. In addition, electric heating or hot water supply type road heating is laid at business offices and private houses to melt snow sequentially, or an embedded snow melting device is installed to melt snow.

[0004]

[Problems to be solved by the device]

 By the way, of the above-mentioned conventional techniques, the method of transporting snow using a large dump truck requires night work to avoid traffic obstacles, and the work time including the transport time becomes long. There is a problem that fuel costs and labor costs are huge every year.Since many rivers are used for snow dumping sites, rivers and estuaries of the sea are polluted with mud, and It is also not desirable from a protection point of view.

On the other hand, when using a road heating system or a snow melting device, operating costs such as electricity and kerosene are incurred every year, and a large amount of snow cannot be processed in a short time because of low snow melting capability. There is a drawback that.

The present invention has been made in view of the above-mentioned problems and drawbacks of the prior art. A snow removal treatment structure capable of treating snow removal at a place where snow has been removed and capable of treating the snow removal at one time. The purpose is to provide.

[0007]

[Means for Solving the Problems]

 A first aspect of the present invention configured to solve the above-mentioned problems includes a snow box for treating snow, which is made of a concrete box having a bottom portion, a side wall portion, and an upper surface portion, and which is buried in the ground. A drainage pipe that is provided in communication with each of the plurality of drainage ports formed in the bottom and extends downward from the bottom, a snow inlet formed in the upper surface, and the snow inlet can be opened and closed. It comprises a closing lid, a safety frame located below the lid and fitted in the snow inlet, and a sewage inlet formed on the upper side of the snow removal treatment tank.

The lid body may be provided with an openable / closable air injection portion communicating with the snow removal treatment tank. Further, it is preferable that a snow discharge guide portion whose upper side surface is an obliquely downward guide surface is located below the safety frame and protrudes from a side wall portion of the snow discharge treatment tank.

Further, a second invention is a snow removal treatment tank which is composed of a tubular body whose upper and lower ends are opened by sidewalls and which is buried in the ground, and an opening on the upper end side of the snow removal treatment tank is opened and closed. A lid body that can be closed as much as possible, a safety frame that is located below the lid body and is provided in the snow removal treatment tank, and a lower portion that is located below the safety frame and has an opening formed in the snow removal treatment tank It consists of a water inlet.

[0010]

[Action]

 According to the first invention, the snow discharge injected into the snow removal treatment tank is gradually melted by geothermal heat, room temperature in the tank, warm rainwater and sewage in summer, and penetrates into the ground through the drainage pipe. . Safety is ensured by the safety frame installed at the snow inlet. By blowing hot air into the snow removal treatment tank through the air injection part, snow melting is promoted. In addition, the snow discharged from the snow inlet hits the snow discharge guide and is scattered into the snow discharge treatment tank. In the second invention, the snowmelt water is discharged into the ground from below the snow removal treatment tank.

[Effect of device]

 The present invention is as described in detail above, and by burying a snow removal treatment tank of a scale suitable for a snow melting location near the snow removal location, it is possible to immediately perform on-site treatment of snow removal. Therefore, it is possible to eliminate the need for transporting snow removal by trucks, etc., and it is possible to significantly reduce the huge snow removal costs such as fuel, labor cost, truck usage fee, etc., which are required every year, and the traffic regulation for snow removal work is minimal. Can be the limit. In addition, the snow discharged into the snow discharge treatment tank can be gradually melted due to the temperature of the ground water, room temperature, and the temperature of rainwater heated by hot summer asphalt and domestic wastewater. . In addition, acid snow, which is currently a problem, can be neutralized, etc., although it is limited to the snow removal tank. Furthermore, since the snowmelt water gradually penetrates into the ground through the drainage pipe, it can help prevent the reduction of groundwater. Furthermore, since the hot air can be supplied into the snow removal treatment tank through the air injection unit, snow melting can be promoted. Furthermore, a snow discharge guide is provided below the snow throwing port to scatter the discharged snow to prevent the formation of snowflakes, so that the snow melting can be performed uniformly and quickly. it can. Also, by constructing the snow removal tank as a cylinder, it can be made smaller for general households and businesses.
