Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a road surface that is effective for cart roads of golf courses, promenades, parks, gardens of ordinary households, sidewalks of ordinary roads, and the like.

<Conventional technology> As is well known, ordinary roads are made of asphalt or concrete, and crushed stones are laid on the top of the roadbed.
Asphalt or concrete is laid on top of this crushed stone to make it flat.

<Problems to be Solved by the Invention> However, asphalt and concrete roads are too hard, so walking on them for long periods of time can cause foot fatigue, and they are unsightly in parks and on promenades. In addition, on golf course cart roads,
When a player walks wearing golf shoes, the spikes make it difficult and dangerous to walk, so thick rubber mats are placed on the floor, but the rubber mats break after a certain period of time and must be replaced. Also, it takes a lot of time and effort to lay down the rubber mat firmly, and it is expensive.

<Means for Solving the Problems> The present invention was proposed in view of the above, and involves binding a plurality of regularly arranged columnar wooden blocks mid-height with a connecting material made of synthetic resin or other material. Then, a roadbed material is laid in parallel on the sand layer, with gaps formed between adjacent wooden blocks and through holes for water passage and piling formed in the connecting material, and each of the through holes Sand is filled in the space below the connecting member, and a fixing device is driven into the ground through the hole, making it extremely easy to walk on.
This provides a road surface that looks good and can withstand long-term use despite the fact that the roadbed material is made of wood.

<Examples> The present invention will be described below based on examples shown in the drawings.

The roadbed material 1 used for the road surface of the present invention has short columnar wooden blocks 2 arranged regularly, and a connecting material 3 made of synthetic resin, rubber, or other material is installed at the middle of the height of each wooden block 2. The wooden blocks 2 are bound together to form a spacing section 4 made of a connecting material 3 between adjacent wooden blocks 2, and through holes 5 are opened at appropriate positions in each connecting material 3. Therefore, the spacing section 4 is vertically partitioned by the connecting material 3 and includes an upper spacing section 6 located above the connecting material 3, and an upper spacing section 6 located above the connecting material 3.
There is a lower spacing part 7 located below the.

In the roadbed material 1 made as described above, each wooden block 2 may be prismatic or cylindrical. Practically speaking, the wooden block 2 may have a width of 100 to 300 mm, a height of 200 to 400 mm, a width of the interval portion 4 of about 10 mm, and a thickness of the connecting member 3 of 5 to 10 mm.
Further, the through hole 5 may be opened at an appropriate position of the connecting member 3, but it is preferable to open the through hole 5 at a position where each corner of the four wooden blocks 2 gather. , the diameter of the through hole 5 can be about 10 mm. Further, the depth of the upper spacing portion 6 may be approximately several millimeters.

Furthermore, when constructing the roadbed material 1, about 4 to 6 wooden blocks 2 are arranged in a grid pattern on one side to form a square shape, and when the roadbed material 1 with a side of about 1 m is constructed It is practical.

In order to manufacture the above-mentioned roadbed material 1, as shown in FIGS. 4 and 5, holes 9 into which the wooden blocks 2 can be inserted are provided in the flat formwork 8 with the width of the spacing 4, and After the pins 10 corresponding to the through holes 5 are placed upright at appropriate positions on the upper surface of the frame 8 and the upper portions of the wooden blocks 2 are inserted into each hole 9, a fluid is formed within the interval between the adjacent wooden blocks 2 on the upper surface of the form 8. supplying the connecting material 3 of
The connecting material 3 is cured and hardened. Once the connecting material 3 has hardened to the extent that it has strength, the formwork 8 is removed downward, and each wooden block 2 is connected by the connecting material 3 to form the roadbed material 1.

In order to construct a road surface using the roadbed material 1 manufactured as described above, as shown in FIG. 3 to 5 layers of sand c are placed on the top surface of this crushed stone b.
cm thick, and the roadbed material 1 is laid on the top surface of this sand layer c so as to be closely arranged in parallel. Then, sand is poured into the lower space 7 of the connecting member 3 through each through hole 5.
A fixing device 11 such as a resistor or a long nail, which is filled inside the roadbed material 1 or driven from above the roadbed material 1, is passed through the through hole 5 of the connecting material 3 and driven into the ground a. In this case, all through holes 5
It is sufficient to use about 1 to 4 fixing devices 11 for one sheet of roadbed material 1 instead of fixing it through the fixing devices 11 through the roadbed material 1.

When a road surface is constructed from each of the sub-base materials 1 in this way, most of the surface of this road surface is formed by the upper surface of the wooden blocks 2, resulting in a road surface that feels significantly different from conventional concrete or asphalt road surfaces. can be formed. Since each roadbed material 1 is fixed by fixing devices 11, it will not shift laterally even if a vehicle passes over the road surface of the roadbed material 1 or a person walks on it, causing shock or vibration. Even if the moisture impregnated in the sand layer c freezes and expands in volume, each roadbed material 1 will float slightly and the road surface will not be undulated, and frost heaving can be prevented.

In addition, rainwater permeates through the sand and sand layer c in the lower space 7 from the through hole 5, and further passes through the crushed stones b and percolates into the ground a, which not only improves the drainage effect but also improves the underground Moisture always flows from the sand layer c to the lower interval 7
Since it penetrates into the sand inside and comes into contact with the side surface of the wooden block 2, it can prevent the wooden block 2 from drying out and cracking.

Although the present invention has been described above based on the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the claims is not changed. can. For example, a cylindrical wooden block 2 can be used, and the surface of the wooden block 2 can be coated with a corrosion inhibitor or hardening agent that does not have a negative impact on humans and animals, in order to increase its strength against corrosion and wear. It can also be impregnated.

<Effects of the Invention> In summary, according to the present invention, a plurality of regularly arranged columnar wooden blocks are bound mid-height with a connecting material made of synthetic resin or other material, and water is allowed to pass through the connecting material. , the roadbed material is laid on a sand layer with through holes for piling, and sand is filled into the space below the connecting material through each through hole, and fixing tools are driven into the ground through the through holes. As a result, it is possible to construct a road surface that is rich in variety that has never existed before. Since the upper surface of the wooden block actually constitutes the road surface, it has flexibility and elasticity, and is particularly effective for roads where people walk, such as golf course cart roads and promenades.

In addition, the through holes of the connecting material firmly support the roadbed material by driving fixing tools into some of them, so it will not shift or come off due to loads, vibrations, shocks, etc. applied to the upper surface of the road surface, and it will not come off during the cold season. Even if moisture near the ground surface freezes, each subbase material will not freeze up. Furthermore, since the above-mentioned through holes also contribute to the drainage of rainwater, rainwater does not accumulate on the road surface. Furthermore, since the spaces between adjacent wooden blocks are filled with sand, this sand stores rainwater that flows in through the holes, absorbs and retains water and moisture from the ground, and causes moisture to flow into the wooden blocks. can be given. Therefore, the wooden block hardly ever dries out and does not crack or shrink or break, so it can withstand long-term use as a road surface and has extremely high practical value.
