Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is an innovative snow removal method that completely changes the conventional snow removal method using water spray nozzles. Water is sprayed in a spray pattern by drilling holes in the pipe in parallel and spraying water from these holes, by burying nozzle pipes in the road surface, or by using various types of disc-shaped water nozzles. This relates to a new spring water snow melting method that aims to melt snow using natural spring water rather than water sprinkling.

[Conventional technology]

Traditionally, snow removal methods for roads, sidewalks, parking lots, etc., involve burying snow-melting water nozzles in the ground in the center or both ends of roads, sidewalks, and parking lots, and spraying water from these nozzles. Snow is removed from roads, sidewalks, parking lots, etc., but if the spouting arches are large, water can splash on pedestrians' clothes or get into their shoes, and the water can be sprayed in large quantities. Water tends to be wasted, and when groundwater is used, this wasteful large amount of watering causes ground subsidence, which is a problem.

[Problem to be solved by the invention]

Rather than using a water spray nozzle, the present invention
This is a completely new snow removal method that uses a water-permeable water-permeable body in the water spraying part, which prevents wasted water and water from splashing on clothes, and achieves efficient snow removal.

[Means to solve the problem]

The present invention will be described below with reference numerals used in the drawings for easy comparison with the drawings showing an example of implementation.

In a snow removal method in which water nozzles are scattered on the road surface and water is melted from the water nozzles to melt snow on the road surface, a water passage body 1 through which water permeates is attached in place of the water spray nozzles, and this water passage body 1 is A snow melting method characterized by supplying a liquid capable of melting snow, such as river water, ground water, hot water, etc. through a water pipe 2, and melting snow around the water passage body 1 with the liquid gushing out from the water passage body 1. This is related.

[Effect]

A liquid capable of melting snow, such as underground water, is introduced from the water pipe 2 to the water passage body 1 arranged in place of the water spray nozzle, and this groundwater etc. gushes out from the water passage body 1, and the snow around the water passage body 1 is melted. Ru.

〔Example〕

The water passage body 1 may be constructed by transporting a water passage block manufactured in advance at a factory to the site and laying it, or the water passage block may be formed on site, or the water passage body 1 may be installed at the location where the water passage body 1 is attached. The water passage body 1 may be filled with aggregate for block molding and hardened and molded on the spot.

Formation at a desired location can be carried out continuously by using a hardening agent such as a two-component resin.

When laying, it can be done manually by mixing the aggregate and the resin used for hardening on site, or it can be done by machine, such as a finisher used for paving.

The water passing body 1 may be formed by mixing a foaming agent when solidifying aggregate such as sand or fine stone with cement, and forming it so that fine voids are created by the foaming agent to form a confectionery-like shape. During molding, gas may be forced into the mold and permeated therethrough, thereby creating fine voids and forming the product in a confectionery-like manner.

The aggregate used for other formations is preferably one with mulch, such as spherical iron slag, to ensure as much water passage as possible, and cheap cement or quick-hardening two-component resin is used for solidification and bonding.

The aggregate used can be colored in any desired color by coloring the two-component cured resin.

Therefore, colors can be selected depending on the situation, such as safe areas, dangerous areas, parks, open spaces, etc.

In any case, it is best to have a void on the average and allow water to flow through the average through capillary action, and various techniques can be considered for forming this.

The water passing body 1 shown in FIG. 1 shows a case in which the water passing body 1 is attached to a channel-shaped water impermeable block 3 made of concrete, for example, and FIG. A case is shown in which a water body 1 is attached, and FIG. 3 shows a case in which a water passing body 1 is attached to the upper surface of a long base-like water impermeable block 3.

When supplying liquid such as river water or underground water to the water passage body 1, a water supply pipe 2' is arranged near the water conduit pipe 2 as shown in Fig. 2, and water is supplied from this water supply pipe 2'. It is also possible to connect water pipe 2 as shown in Figure 3.
The water may be supplied from a water discharge pipe 5 provided in the.

Figure 4 shows a case in which rectangular water passages 1 are dotted around the center of the roadway, and water passages 1 are attached along the entire length of the sidewalks on both sides of the roadway. A case is shown in which the water passage bodies 1 are attached over the entire length, and the rectangular water passage bodies 1 are dotted and attached at the outer ends of the sidewalks at both ends of the roadway.

The water guide pipe 2 shown in FIG. 6 is formed to become gradually thinner as it reaches one end, and small water discharge holes are bored at regular intervals, and a drain valve 6 is provided at the end.

FIG. 7 illustrates a case in which water is not directly discharged from the water conduit 2 but is discharged from the water discharge pipe 5.

In this case, in order to keep the amount of water discharged constant, a short water discharge pipe 5
The water pipe 2 is connected to the water pipe 2 through a branch pipe 7.

This water discharge pipe 5 is provided with a drain valve 6.

Similarly to FIG. 7, FIG. 8 also consists of a water discharge pipe 5 and a water guide pipe 2, and shows a case where the water guide pipes 2 are directly connected to each of the short water discharge pipes 5 to uniformly discharge water.

A drain valve 6 is provided at the end of the water discharge pipe 5.

6, 7, and 8 all illustrate the case where a submersible pump is used as the pump 8.

In addition, as shown in FIG.
If a large number of solar heat collecting pipes 9 are installed, underground water is pumped up from a well through the heat collection pipe 9, the groundwater is guided, and then piped back to the well, solar heat can be stored in the ground water in midsummer through the heat collection pipe 9. If this heat-stored groundwater is used in the winter, the warmer groundwater can be used, and the snow-melting effect can be improved.

In addition, when it comes to piping, the principle of double and single piping for conventional sprinkler nozzles is applied as is, and in the case of single piping, the farther away from the pump, the weaker the water pressure becomes, resulting in no spring water on average.

In order to correct this defect, as shown in Figure 2, double piping is made with water conduit 2 and water supply pipe 2', water is sent through thick water conduit 2, and water is branched to water supply pipe 2' for watering. A water volume adjusting pulp is provided for each water supply pipe 2'.

FIG. 9 shows a case where the water supply hole 4 is directly drilled in the water conduit 2, and FIG.
Fig. 11 shows a case where a water discharge pipe 5 with a water supply hole 4 drilled in the water conduit 2 is installed upright, and Fig. 12 shows a case in which a horn type water supply hole 4 is protruded from the water conduit 2 This shows a case where a water discharge pipe 5 is installed upright.

Further, a part of the existing snow-melting device using the water sprinkling method may be changed to the gushing method of the present invention.

〔Effect of the invention〕

The present invention provides a water passing body 1 through which water permeates as described above.
is attached to the water sprinkling surface instead of a water nozzle, and is provided so that liquid such as river water or underground water is supplied into the water passage body 1 through the water conduction pipe 2. When a liquid such as river or marsh water or groundwater is supplied, the liquid such as river or marsh water or groundwater oozes out onto the surface of the water passage body 1 due to the permeability of the water passage body 1, resulting in a state similar to that of getting wet with rain. Snow melts gradually, making it possible to melt snow very efficiently without getting clothes wet with water sprinkled with water nozzles or wasting important groundwater by sprinkling large amounts of water, as in the case of conventional methods. become.

Moreover, the water passing body 1 does not spray water from the nozzle hole like a conventional water sprinkling nozzle, but water oozes out to the surface due to the water permeability of the water passing body 1 itself, so there is no corresponding nozzle hole, so it may become clogged. This phenomenon does not occur at all, and even if the surface is scraped by driving, you only need to repair the scratched areas, such as on asphalt pavement or concrete pavement.Compared to conventional water nozzle replacement work. This can be done extremely easily and efficiently.

In addition, if the snow removal method according to this method is adopted, the following characteristics will also be exhibited.

1● Damage or friction of the nozzle ● Clogging of the nozzle ejection (water sprinkling) hole ● Nozzle adjustment and cleaning inside the nozzle before winter ● Hazard to pedestrians etc. due to variations in the amount of water sprayed by the nozzle ● Water sprinkler facility (water intake facility) - Disadvantages of mechanical snow removal in case of breakdown - Disturbance to the aesthetic appearance of the road surface and traffic safety - Disturbance due to the difference in friction between the asphalt and concrete due to the enlarged excavated cross section - Disturbance due to damage or cracks in the concrete wrapped around the piping - Harmful effects of water leakage from piping joints and nozzle surrounds on the lower and upper roadbeds; Inconveniences of conventional water fountain (water spray) methods using water spray nozzles, such as the inconvenience of replacing nozzles and the inconvenience of raising the height of the nozzles at the same time due to raising the road surface. Irrationality can be resolved all at once.

2. Completely freed from the inconvenience of nozzle repairs and water volume adjustment before winter and measures to prevent traffic accidents, snow can be easily melted with spring water at any time of the year with peace of mind.

3 When installing conventional water spray nozzles, especially on roadways, almost all pipes are made of steel pipes, so changes in temperature or force due to transport loads can cause pipes to break or joints to break, which can be a major cause of water leakage. However, the spring water snow removal water pipe of the present invention is not only an iron pipe but also a resin pipe that can be used freely, and it does not require the use of expensive watering nozzles per piece, and it can be glued. It is possible to use materials that are cheaper than steel pipes, and because it requires almost no maintenance, the so-called initial cost and running cost of construction and maintenance can be lower than the nozzle watering method.

4 The minimum excavated cross section of the road surface in construction is 30cm wide x 30cm deep for nozzle-mounted construction, so at least the concrete width above ground is 30cm wider than that created by nozzle-mounted piping on general roads. Although it may cause a big problem in aesthetic appearance, maintenance, and wheel traffic, in this invention, the width of one water passage on the road is 10 cm instead of 5 cm.
However, it can be made narrower in any way possible, and it also means that when wheels wear out due to traffic or when the road surface is raised, it can be repaired easily and at low cost in a short period of time, reducing work time. This will also help reduce time and prevent accidents.

5 This water passage body 1 can be colored, so it can be colored white or yellow and used as a center line of a roadway, a crosswalk line, a sign written on the road surface, etc.

As mentioned above, this is a snow removal method that exhibits many excellent features.
