2. Description of the Related Art Conventionally, at a civil engineering work site, in order to secure a passage for work vehicles, large construction machines, etc., in order to secure a passageway, be sure to make an embankment at a predetermined place, and to roll the portion. A temporary road is constructed by laying an iron plate on the upper part as appropriate.

However, the construction work of the temporary road has the following problems.

In order to carry out embankment, it is necessary to improve the ground and convey a large amount of earth and sand with a dump truck or the like.

A heavy iron plate must be laid one by one on the embankment.

Even if an iron plate is laid on the embankment, if the ground is loose, the embankment (particularly the side surface) gradually sinks or collapses due to repeated traffic of work vehicles and rainfall. Furthermore, this repair is very troublesome because the iron plate must be removed one by one.

After the completion of construction, the embankment must be removed to return to the current state.

As described above, the construction of the conventional temporary road is very troublesome, and thus there are problems that the construction cost is too high and the construction period is extended.

The present invention provides a temporary road that solves the above problems.

The present invention relates to a temporary road characterized by the adoption of.

The temporary road according to any one of claims 1 and 2 relates to the temporary road characterized in that styrofoam is adopted as the foam material 1.

In the temporary road according to any one of claims 1 to 3, when the laying members 2 as the temporary road 6 are two bodies in the width direction of the temporary road and two bodies in the height direction of the temporary road, The present invention relates to a temporary road characterized in that the upper laying member 2 and the lower laying member 2 are arranged in a staggered manner in a vertical cross-sectional view in the width direction of the temporary road.

The temporary road according to claim 4, wherein the laying members 2 are arranged in n steps in the height direction of the temporary road.

[0016]

The temporary road is constructed by appropriately connecting the laying members which are light inside because of the foam material and solid outside because they are made of steel or FRP.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show one embodiment of the present invention.
This will be described below.

A laying member 2 is provided. The laying member 2 is a rectangular parallelepiped box made of steel or FRP and filled with styrofoam as the foam material 1 (appropriate reinforcing member may be arranged inside), and its dimension is (2.0). m × 1.0m
X 0.5 m). Eight through holes 2a extending from the upper surface to the lower surface are provided at appropriate positions of the laying member 2. The openings of the through holes 2a are opened in the recesses 2b formed on the upper surface and the lower surface of the laying member 2. This is to prevent the connecting rod body 3 and the nut 4 from protruding from the surface of the laying member 2 when the connecting rod body 3 described later is inserted into the through hole 2a and the nut 4 is screwed onto the connecting rod body 3. In consideration. Therefore, the passage of the work vehicle is not hindered at all.

Styrofoam is a material weak against gasoline and ultraviolet rays. The laying member 2 of this embodiment is provided with steel or FRP as the hard member 7 on the outside. Therefore, the steel or FRP of this embodiment also plays a role of protecting the polystyrene foam inside.

As the laying member 2 for the end portion, the laying member 5 for the end portion having a width half that of the laying member 2 is prepared. The end laying member 5 has the same structure as the laying member 2, and the through holes 5a are provided at four places.

A connecting rod body 3 is provided. The connecting rod 3 has through holes 2a provided in the laying member 2 and the end laying member 5,
A male screw portion 3a for screwing a nut 4 is formed at both ends of the connecting rod body 3 so as to be inserted therethrough.

Since this embodiment is constructed as described above, a method of constructing the temporary road 6 in which the laying members 2 are arranged in two steps, upper and lower, will be described with reference to FIGS. The connecting rod 3 is inserted from the lower surface side of the through hole 2a and fixed by the nut 4 (the connecting rod 3 is in a state of protruding from the upper surface of the laying member 2 in this state), and the laying member 2 The laying members 2 are arranged side by side in the three-body road direction such that the long sides of the laying members 2 are in the road length direction, and the end laying members 5 are arranged side by side on the left and right ends of the laying member 2. A predetermined number of the laying member 2 and the end laying member 5 are laid in the length direction of the road (lower side in FIG. 1) to form a lower stage.

Then, the connecting rods 3 protruding in the lower stage are fitted with the through holes 2a of the laying member 2 so that the long sides of the laying member 2 are in the width direction of the road, and the connection is made. Stick 3
The nut 4 is fastened to the upper end of the above, the upper stage is laminated to the lower stage, and finally the end laying member 5 is laminated to the end portion in the lengthwise direction of the road, and similarly, the connecting rod 3 and the nut 4 are fastened. When forming the upper tier and the lower tier, the upper tier is arranged so as to deviate from the lower tier in both the road length direction and the road width direction in order to ensure strength (durability).

Since the end laying members 5 are arranged at the lower end of the road in the width direction and the upper end of the road in the length direction, a step difference is caused by disposing the upper part and the lower part offset from each other. Has been resolved.

Therefore, this embodiment has the following effects.

There is no need to perform ground improvement or carry a large amount of earth and sand for embankment as in the conventional case, and the lightweight and solid laying member 2 and end laying member 5 that have been created in advance are used on site. Since it suffices to carry it up to and lay it appropriately, the construction cost and the construction period can be significantly reduced, and the temporary road 6 can be constructed without destroying the natural environment.

Further, after the construction is completed, the lightweight laying member 2
It is only necessary to remove the embankment, which eliminates the conventional embankment and eliminates the need for work to restore it to the current state, further shortening the construction period.

Further, even if the ground is loose, the temporary road 6 has the laying members 2, the laying members 5 for the end portions, and the connecting rods 3.
Also, since the upper and lower tiers are connected to each other vertically and horizontally by shifting, the temporary road 6 does not have to be partly submerged.

Further, since the present embodiment can be constructed by laying the laying member 2, it is possible to easily construct a temporary road having a high height or a temporary road having a large width.

Further, according to this embodiment, since the laying member 2 can be repeatedly used, it can be reused at another construction site after being used at one construction site, which is economically excellent in this respect. It becomes a thing.

[0031]

Since the present invention is constructed as described above,
It will be possible to construct a temporary road very easily.
