Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a construction method for a temporary road.
In particular, it relates to a construction method for temporary roads for passing trucks and transporting other equipment at work sites in wetlands and the like.

[Prior art and problems to be solved by the invention] Conventionally,
When heavy goods vehicles such as trucks pass through wetlands etc.
There is a phenomenon in which the trucks are unable to pass through the wetlands and become stuck.

In order to overcome this problem, a service industry has developed that provides day laborers who lay gravel, etc., and workers who lay boards. However, planking requires boards that are 10 to 20 feet long, 1.5 to 2.5 inches thick, and 6 to 8 inches wide, so they are very heavy, and for roads, they are 8 to 8 inches wide. It required manual labor to lay boards over a distance of 14 feet and several miles. This board is by no means cheap, and even after it is used, it requires labor to carry it on board or store it, and the work of separating it is also not easy. - Large nails are usually nailed into boat fishing equipment, and this removal work is often extremely difficult.

Not only does the construction of such plank roads require a great deal of labor, but the weight of the planks also poses great danger in assembly.

Furthermore, the huge number of legs on the board also increases the amount of work.

As mentioned above, board-paved roads have many problems, and their lifespan, such as the number of times they are used, cannot be said to be long from a cost perspective. Furthermore, the fact that they are often destroyed during separation is a major cause of shortening their lifespans.

Therefore, a technical problem arises that must be solved in order to overcome these defects, and the present invention aims to solve this problem.

"Means for Solving the Problems" This invention was proposed to achieve the above object, and is a temporary road for installing or passing equipment and transport vehicles on rough ground, A plurality of screens are provided in which a first screen board and a second screen board are combined as one unit, (
b) The first screen plate constitutes the ten-sided part, and the second screen plate constitutes the lower surface part; (c) And when the screen is attached to waste land, the first screen plate of the first screen and the next screen (c) the first screen plate is configured to be in contact with the second screen plate of the third screen plate, and the first screen plate of the third screen plate is configured to be in close contact with the second screen plate of the second screen plate; The third screen is arranged vertically, and the fifth screen is similarly connected to form the upper or lower surface of the road, and the second screen connects the first screen and the third screen. To provide a construction method for a temporary road, which is characterized in that the second screen board of the first screen and the third screen and the second screen board of the second screen are connected in a mating state. That is.

[Function] The present invention is an improved construction device for boardwalks, and does not require on-site nailing work. In other words, the screeners are manufactured to specifications for each unit, and each screener can be unloaded and connected in the same way at the site, making installation and recovery after use extremely easy. It can be done quickly, saving time and labor costs. Furthermore, the road width can be easily expanded or reduced by adjusting the planking mechanism. Furthermore, the direction of expansion is not limited to the width direction of the road, but may also be radial.

``Example'' Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings. Figure 1 shows the upper screen plate (121) and the lower screen plate (14
) is illustrated. This board set (1
0) will be called a bamboo shoot. The upper screen plate (■ indicates the screen plate) that constitutes this screen. Screen-like plates (1
G (IFF... consists of weight equipment and transport vehicles,
It will support the width and length. As can be seen better in Figure 2, several second lower screen plates (Y) are combined to form the screen plate (A), and the screen-like plates (I [9) are supported in an intersecting manner. The screen boards (A) are arranged at equal intervals, and the reason for this will be understood in the detailed explanation below.

3 and 4 show a temporary road construction device. In FIG. 3, the screen (2) and the screen (2) are combined so as to be in contact with each other, and are connected by a third screen (4) as can be seen from the side view of FIG.

The first screen (A) consists of a two-part screen board (A) arranged at a certain interval, and a lower screen board (1) 021 (B) arranged so as to intersect with the upper screen board. It consists of

Similarly, the first screen (1st screen) consists of a two-part screen board (G) and lower screen boards (40), (42), (44), etc. arranged at appropriate intervals.

These first screen and second screen (b) are separate screens, i.e.,
They will be connected by a third screen to form a road.

This point is an important point of the present invention.

The first fence (2) and the second fence (2) were constructed for temporary road construction.
As mentioned above, the third part (a) that connects 4) is required, but this third part also has the same structure as the first and second screens, and is connected to the first screen indicated by the symbol (48). Board and (50
) (52) It consists of a second screen plate indicated by the symbols (54) and (56). Said second screen board (5 (1
) (52) (54) (56) is a horizontal board and a vertical board (48)
is supported. As shown in Figures 3 and 4, during construction, the third screen board is installed first, but the first screen board is placed on the ground G side, and the second screen board (50) etc. are installed. towards the top
and set it in place. Then, as the next step, the first sanshi (a) and the second sanshi tsutomu are placed in the second position. In that case, sign (a)
The parts of (A) and Tsutomu (4φ) are in close contact with each other, and in addition, they are in contact with the horizontal plates (54) and (52) of the third screen so that they can withstand the longitudinal force of the road. It forms a strong bond.

Thus, by using this method, the temporary road will have a three-tiered structure. The second screen plates (lower screen plates) of each screen mesh with each other to create a bonded state, and the first screen plates on the upper and lower surfaces constitute the longitudinal structure of the road. The triple structure with this interlocking mechanism creates a seamless shape in the direction of the road, and has the advantage of applying a uniform force to the ground surface in contact with the road board. Efforts to make the load distribution more uniform are particularly important under soft ground conditions, and are an essential condition for temporary roads.

Although explanations have been omitted in the basic concrete examples shown in Figures 1 to 4, in some cases, it may be necessary to use other methods to connect the screens as described above. do not have. In the basic example, the only connection was the engagement of the second screen board, but by attaching the stakes and receiving chambers to the screen as shown in (10), the stakes of the first screen fit into the receiving chambers of the second screen. In this way, positioning can be performed correctly. This includes:
Various ideas may be possible. As an example, it is effective to place stakes along the center line of the two outer plates of the cross support plate (A) in Figure 2, and install a receiving chamber within the bottom surface of the screen plate (10). It would be a good idea to attach a receiving chamber on a line parallel to (a) of one screen that is offset from the center line, and attach a stake on the opposite side of that line and the center line.Similar to this screen. Next, combine another screen equipped with stakes and receiving chambers so that the stakes and receiving chambers match, and then combine another screen in the same manner.Then, this screen is also a unit that can be replaced. This idea could be extended to include a more reliable bayonet structure for the relationship between the receiving chamber and the pile, or even more securely by using a cable connection method.

Although such a screen has been explained above as being rectangular, the concept is the same whether it is square or fan-shaped which can be expanded radially. In addition to this,
Various applications are possible without departing from the spirit of the invention.

So far, we've talked about using wood boards, but they can be made using other fibers, polyurethane, fiberglass, and similar combinations. It is also effective to selectively use these materials in order to take advantage of the spirit of the present invention.

Furthermore, as stated above, in keeping with the spirit of the invention, the screen may have various dimensions and materials selected depending on the purpose.

I'm not trying to limit things here, but just to give an example, but there are various ways to consider the quality and shape of the materials, such as metals, alloys, lumps, steel, angles, steel plate reinforcing bars, etc. can.

In addition, the screen can be made of fiberglass, plastic, rubber, or a combination thereof, and these can be considered highly desirable applications.

It is also conceivable that the material could be made of old car tires. This can be made to have the necessary strength and durability through various treatments. It can be bonded by a wide variety of bonding mechanisms, solidified, and pressed into a desired shape for use. This material can also be combined with other materials to create a bond between recycled tire rubber and twilled fibers in a process similar to the drawing process used to make fiberglass or the compression process used to make cast concrete. . The method of irregularly mixing fine fibers also allows easy addition and is promising as a method of bonding process performed as a preliminary step to solidification and reinforcement.

Curing of the material can be done in various ways by heating, chemical reaction, or a combination thereof.

Each part of the horizontal and vertical plates can be designed and manufactured by arranging the optimal fiber structure at the optimal position depending on the force to which it is subjected. Fibers that are resistant to longitudinal stress, such as Aramid or EULAR, can be formed into glass fibers by drawing methods. Although it may be better to call such linear fibers or cables, they are also
It is also useful for connecting individual bamboo screens vertically. In this way, if the vertical cables are used effectively, it is structurally possible to connect the entire structure as if it were a single piece and add the necessary strength. Plywood can be used instead of the solid wood shown in the diagram. Screens may also be available as high strength, low density compression casts.

All of the above-mentioned examples are effectively combined and utilized to meet the requirements for the construction of temporary roads with interlocking mechanisms, such as durability, local conditions, soil, cost, transportability, and number of uses. It is desirable that

Although the invention has been described using one particular embodiment, it is in no way meant to be limited thereto. Obviously, technical modifications may be made without departing from the scope of the invention.

[Effects of the Invention] As described in detail in the above-mentioned embodiment, the present invention mainly provides a screen consisting of a first screen plate for supporting a transport vehicle and a second screen plate that connects this screen plate. It is made by preparing many pieces. When installing the first screen with the first screen board facing upward and the second screen board facing downward, install the second screen board upside down and connect the second screen boards so that they interlock with each other. . Place the third screen in the same direction as the first screen, and the fourth screen in the same direction as the second screen, so that they are lined up alternately and fixed to each other.

In this way, the first, third, and fifth screens support the transport vehicle.
The second, fourth, and sixth screens are used as the lower side screens that touch the ground. In this way, the temporary road can be expanded not only vertically, but also horizontally at the same time. Furthermore, it can be manufactured to allow for lateral expansion to create working space. Although in the Preferred Embodiments section the road is depicted as being made of wood, in reality it could be made of any other suitable material, i.e., lightweight, strong fibers or fiber bonding materials. You can also make one.
