Description

[Detailed Description of the Invention] This invention relates to a completely new method for forming a lightning-extinguishing road surface for easily eliminating snowy or frozen conditions on airport runways, roadways, sidewalks, etc. in snowy areas. .

The methods that have been commonly used to create a lightning-extinguished road surface include the use of lightning-extinguishing vibrators to constantly sprinkle ground water, road heating with heat wires embedded in advance, etc. Alternatively, methods such as chemical spraying have been effective to some extent depending on the application.

However, with these conventional methods, it is almost impossible to easily create a lightning-extinguished road surface whenever necessary or to reliably eliminate a large amount of snow that has occurred in a short period of time. It cannot contribute in any way as a method of extinguishing lightning in places where economic activity requires countermeasures against snow damage, such as runways in rural areas, bridge surfaces that are prone to ice, roads and parking lots with no snow removal space in urban areas, etc. Ta.

In view of these current circumstances, the present invention aims to develop and provide an effective method for reliably forming a lightning-extinguished road surface in locations where conventional means cannot be used.

The details of the configuration will be explained below along with each figure shown to explain this invention.

First of all, this invention basically consists of a snow melting device 2 and a snow melting groove 3 arranged below a large number of prismatic roadbed blocks 1. This is achieved by forming the roadbed in areas that require lightning extinguishing. That is, the snow melting groove 3 is formed below the road surface at the location where lightning extinguishing is required, at least in a space that is larger than the space in which the subgrade block 1 (described later) can rotate around its axis. . As shown in the second side sectional view, this snow melting groove 3 has a bearing that supports the shaft centering of the subgrade block l.
In addition to forming a snow melting groove 3 made by pouring concrete that also serves as the foundation structure of the roadbed itself, although not shown in the drawings, when forming the bearing recess 4 as an independent foundation structure, etc. In particular, it can also be formed as a simple excavated trench without having to pour concrete all over. Above the snow melting groove 3 formed to a predetermined width and depth,
In the bearing section 4, a large number of prismatic roadbed blocks 1 each having their axis 12 ends supported are horizontally arranged side by side, and each roadbed block 1° 1... has a negative surface 11. When the old .

This roadbed block 1 is shown in the cross-sectional view shown in the first figure.
In addition to being constructed of triangular prism-shaped blocks with a substantially triangular cross section, it can also be realized by square prism-shaped blocks or other prismatic blocks as shown in Figure 4, but each subgrade block 1
．． 1. Guarantees the rotation of..., and its - side 11.11
A triangular prism shape is most suitable in order to minimize the gap between each roadbed block when forming a flat roadbed surface by making it continuous. Then, the width dimension of one side of this prismatic roadbed block l (i.e.,
Of course, the length of one side in the cross-sectional shape is not particularly limited, but for general roads etc., it is slightly smaller than 1~
Approximately 2ffi, or 3-5m more on runways etc.
It is made of prestressed concrete or steel.

This prismatic roadbed block 1 is supported by a bearing section 4 at both ends of its axis ν, and is arranged horizontally in large numbers, and a rotating device is installed for each subgrade block 1, or Or the first
As in the example shown in the figure, several roadbed blocks 1.1...
When desired, each roadbed block 1.1... is rotated by equipping a rotation device (drive motor) 5 which is linked with a transmission shaft or a chain belt 51 etc. It is planned to ensure implementation.

In addition, if necessary, as in the first example, a connecting plate 13 is formed which can be freely inserted into and taken out from one subgrade block l to the other adjoining subgrade block l, and a reversible motor or hydraulic device is provided. If it is linked to 14, each of the parallel subgrade blocks 1, 1, 11, 11, 11, etc. will ensure a flat roadbed surface in the form of a continuous plate It will be formed as follows. In the example shown in FIG. 4, the connecting plate 15 corresponds to the connecting plate 13, the chain gear shown in the figure, → indicates the tension bolt for assembling the roadbed block, and 41 indicates the transmission core.

On the other hand, each roadbed block 1. formed as described above.
1. A snow melting device 2 consisting of a heat pipe or the like is formed below the subgrade block 1 at a position that does not impede the rotation of the subgrade block 1 and is closest to the subgrade block 1. Thermal energy is supplied as necessary to the other surfaces n', n'', . In addition, for the purpose of increasing the thermal efficiency of this snow melting device 2, for example, a heat pipe is used.

In addition to the heat radiating parts such as hot wire heaters and steam pipes being fixedly installed at the closest location that does not interfere with the rotation of the subgrade block 1 as in the above embodiments, the heat radiating parts themselves are movable, When the subgrade block l rotates, it is moved to a position that does not interfere with its rotation, and it is planned so that it can come into contact with or get very close to the subgrade block 1 only during heat dissipation, or each surface of the subgrade block l Naturally, means such as embedding and fixing a heat dissipating section in advance in the snow melting device 2 of the present invention may also be adopted, such as using the axis of the subgrade block '1 to transport energy. can.

As represented by the above example, when a roadbed is constructed at a location where lightning extinguishing is required, and the roadbed surface of the circuit board becomes snowy or frozen, which poses a problem for the purpose of its use, Rotate each subgrade block 1.1...
One side of the lock 11', 11'
- Rotate until the road surface becomes as horizontal as possible. For this rotation angle control, any known control device that can automatically control the rotation angle to an appropriate angle according to the cross-sectional shape of the roadbed block 1 can be employed.

In this rotation operation process of the subgrade blocks 1, 1..., each subgrade block 1, 1..., as shown in FIG.
...At the same time as a predetermined gap is formed between them, one side 11 of the subgrade blocks that had previously formed the subgrade surface is tilted and reversed, so that the snow or ice mass in the same place naturally moves downward. It falls into snow melting ditch 3. Then, when the predetermined rotational operation is completed, the snow melting device 2 is activated, and the surface of one side 11 of the subgrade block l that had formed the subgrade surface up to that point, and if necessary, a new subgrade surface is added. The surface of the other surface 1 to be formed is also heated at the same time to maintain a dry surface. Due to the heat dissipation of the snow melting device 2 and the running water on the surface of the subgrade block surface 11 released by the heat, the snow or ice blocks that have fallen and accumulated in the snow melting groove 3 are also melted and drained.

In this way, the roadbed surface that had previously been covered with snow or ice turns into a dry roadbed surface, and while it functions as a roadbed surface according to the purpose, it also Since the other surface of the floor block 1 is prepared to form a new road surface, a similar lightning extinguishing road surface can be formed any number of times thereafter at predetermined time intervals.

Of course, when forming a lightning extinguishing road surface by the above method, if the connecting plate 15 or the connecting plate 13 is formed on the subgrade block 1, they can be connected to a reversible motor or oil leveling device, etc. After being retracted by operation, the roadbed block is rotated, and after the rotation is completed, it is pulled out again to form a single plate-shaped roadbed surface as a whole. As diagonally above,
The method for forming a lightning-extinguishing road surface of the present invention involves creating a roadbed by horizontally arranging a large number of prismatic roadbed blocks each having a plurality of surfaces to serve as the roadbed surface, and forming one surface of the plurality of surfaces at an appropriate time. Since it is rotated and used as a roadbed surface every time it is placed,
To surely realize a roadbed surface in an ideal condition when necessary even in an area with heavy snowfall. Moreover, if we try to achieve a roadbed surface close to this state using conventional means (it is impossible to achieve an ideal roadbed surface in a state that can be achieved with the present invention using conventional means, but with this invention, , most of the snow or frozen part falls into the snow melting groove, and only the remaining part needs to be melted, resulting in extremely low thermal energy consumption.Therefore, it is necessary to carry out this invention. Even if the construction of the roadbed that will become The construction of the subgrade block itself can be assembled on-site using E, which is made into a brevap, and all that is required on-site is the construction of the snow-melting groove and the installation of the bearing section (which can also be used as the structure of the snow-melting groove). This is necessary and will lead to a shorter construction period.

In particular, when this invention is adopted as a runway for an airport, a somewhat uneven ground surface is left as it is, and a bearing is constructed on the ground surface in the form of a pedestal. Because it is possible to create a runway in a deck-style manner by passing over the roadbed blocks, it is extremely effective not only in terms of land preparation, but also in terms of work processes and maintenance management during use. To become a. This advantage naturally applies to the case where the roadbed block itself is used as a bridge road surface, etc., and furthermore, it becomes possible to use the roadbed block itself as a bridge girder structure. On the other hand, if it is applied to roads in shopping districts and extremely densely populated old urban areas, it will be possible to completely eliminate snowpack from the roads by blocking traffic only during specific hours, eliminating the need to worry about where to remove snow, and , it is also possible to eliminate the situation where the entire road is flooded with water, which was the case with previous methods. As well as other features of the lightning extinguishing effect,
The economic effects that accompany or spread from it can be said to be immeasurable.
