2. Description of the Related Art Conventionally, when constructing a specific land for the purpose of civil engineering, construction, etc., it is necessary to secure a road for approaching it, a material storage site for construction, or a building site such as a construction office. . It is good if the land and roads necessary for this purpose are close to or adjacent to each other, but if it is necessary to separately treat them, the fields, soft ground, and the slopes of the adjacent areas are designated as temporary roads or temporary ground. It was constructed, and after construction, it was originally removed and repaired. Soil such as mountain sand and lightweight concrete were used for the construction of this temporary road and temporary ground.
Since various heavy equipments and many transportation and carrying-out means are required, and the cost and labor are great, improvement thereof has been demanded.

For this purpose, for example, there was an idea to use the Styrofoam block used in the EPS method for such an application, but the block is relatively expensive as compared with earth and sand, and is recovered at the time of restoration. The question of what to do with the block remained unresolved. That is, the incineration after the collection, the volume reduction / melting treatment, or the disposal treatment cost becomes too large, which hinders its practical use. Furthermore, even if these blocks are reused, it is difficult to maintain the quality for reuse because the surface is polluted and damaged, and the management for reuse such as collection, storage and transportation is profitable. The reality was that it did not hold true.

FUNCTION AND EXAMPLE The foamed synthetic resin block of the present invention refers to a block-like material made of various kinds of foamed synthetic resin and is not particularly limited. EP in general
For example, foamed synthetic resin blocks such as Styrofoam blocks for embankment which are used in the S construction method and commercially available are exemplified, but not limited to these, and a substantially rectangular shape is used as a representative example, and H type , C type or the like can be used.

Examples of the foamed synthetic resin include styrene resin, ethylene resin, olefin resin such as propylene resin, and synthetic resin such as urethane resin, and the thermoplastic resin is particularly preferable. These synthetic resins are, for example, foamed and molded by using a commonly used foaming agent or the like, for example, by a foam molding method such as a bead method in-mold foaming method. It is not limited by the method.

From the viewpoint of cost and performance, polystyrene or polyolefin such as polyethylene or polypropylene is preferable, and polystyrene is particularly preferable. Examples of the styrene-based resin include polystyrene, polystyrene obtained by copolymerizing styrene with α-methylstyrene, maleic anhydride, acrylic acid, acrylic acid ester, methacrylic acid and methacrylic acid ester, and polystyrene with styrene. -Butadiene rubber (SBR) and the like are appropriately added and modified. Also,
As for the polyolefin, random, block, graft and other copolymers can also be used.

The surface material is a shrinkable synthetic resin film or sheet having a property of shrinking and covering by heat or the like, a so-called polyvinyl chloride, synthetic resin shrink film such as polyethylene, or chloride such as polyvinyl chloride. A synthetic resin film or sheet made of vinyl resin, polyolefin resin such as polyethylene and polypropylene, polyester resin such as polyethylene terephthalate, and other synthetic resins. Also, woven or non-woven fabric made of synthetic fiber or natural fiber, paper, paper base material such as cardboard,
Furthermore, plastic corrugated board and the like are exemplified, but the invention is not limited to these, and a composite material in which these are appropriately combined can also be used.

Of these films or sheets, those obtained by adhering or embedding net-like plastics to reinforce are preferable as the surface material from the viewpoint of strength. It is also possible to coat the surface of the foamed synthetic resin block by winding the surface of the foam synthetic resin block by using one of these surface materials coated with an adhesive or a pressure sensitive adhesive. For example, using a material such as a wide gum tape, the one covering the surface of the foamed synthetic resin block becomes very strong in terms of strength,
The peeling of the surface material after use is simple and is one of the preferred embodiments.

That is, the surface material of the present invention means that when the foamed synthetic resin block of the present invention is used for civil engineering and / or construction applications, sea lake floating surface applications, etc., the surface of the blocks is contaminated, polluted or damaged. Placed in an environment that will be damaged, but protects the surface of the foamed synthetic resin block and contaminates these,
Any object can be used as long as it achieves the purpose of preventing or preventing damage.

The foamed synthetic resin block of the present invention has a part or all of the surface thereof covered with these surface materials. Preferably at least 4 sides, more preferably 6 sides
It is desired that the surface is covered with a surface material. The foamed synthetic resin block is used for civil engineering and / or construction applications, sea lake water floating body applications, etc., and then, with or without removing these surface materials, the surface of the foamed synthetic resin block is contaminated or polluted. Prevent or reduce damage and damage, and cut it to the required size for reuse. Generally, these blocks are often cut by heat generated by energizing a nichrome wire, but when the surface of the foamed synthetic resin block is contaminated with earth and sand, it is difficult to cut it well.

However, in the present invention, since it is protected by the surface material, this cutting can be performed satisfactorily, and
Since the damage is often small, there are many parts that can be reused, so economic efficiency is also very good. Especially when a good surface material having high strength is used, the recycling rate increases. However, because of cost constraints, the most suitable surface material may be selected according to the purpose.

The cutting is not limited to the nichrome wire, but may be a cutting such as a general circular saw, a saw such as a band saw, or other cutting means, and the cutting means is not limited. . Covering with the surface material covers the whole surface or a part with a shrink film, or a part of the surface of the foamed synthetic resin block by a synthetic resin film or sheet, synthetic fiber or natural fiber woven or non-woven fabric, paper, etc. Alternatively, all means may be covered, or the surface may be attached or adhered, or applied or sprayed.
Further, it is also possible to store in a bag-shaped product made of a synthetic resin film or sheet, synthetic fiber or natural fiber woven or non-woven fabric, paper or the like.

It is preferable that these surface materials can be easily removed after recovery, but there is no particular problem even if they are adhered or attached to the surface without being removed. In this case, it is also possible to wash the soil and the like adhering to the surface of the surface material and then cut the surface material with the surface material adhered or adhered.
Furthermore, if a band-shaped body made of synthetic fiber or natural fiber woven cloth or non-woven cloth is hung or tied at one or more places on the surface of the foamed synthetic resin block covered with the surface material, the surface material and the Or, it can be used for fastening the reinforcing material, and it is convenient to carry one by one, and it is also possible to connect the foam synthetic resin blocks to each other by connecting these strips for each block to each other. Use a crane, etc. to prevent collapse and remove / collect
It is convenient because it can be loaded on a transportation vehicle etc. with a plurality of blocks connected at once.

The reinforcing material of the present invention is, for example, a plywood board,
It is preferable to use a punching metal, expanded spanning board, etc. that has a greater strength than the foamed synthetic resin block, and when using the foamed synthetic resin block, it is more sufficient than the surface material, or in combination with the surface material, the foamed synthetic resin. It is a measure to prevent damage or contamination of the block surface.

The size of the foamed synthetic resin block of the present invention is not particularly limited.
The size and weight convenient for people to carry are naturally decided, and the size of 2m x 1m x 0.5m is commonly used. On the other hand, as the plate-like body used for construction purposes, those having a size of 1820 mm × 910 mm are mainly used due to the general size of building materials.

According to the present invention, when these foam synthetic resin blocks for embankment are used and then cut and reused for construction purposes, the waste amount of the blocks is small and resources are utilized to the maximum extent. It has been found that the cost can be reduced accordingly and the cost can be reduced accordingly.

Even if it is used for purposes such as seawater floating bodies and sea lakes, pollution, pollution, damage, etc. can be prevented and prevented.

Further, since the reinforcing material is interposed between at least one surface of the foamed synthetic resin block and the surface material, the surface strength is further improved and damage by heavy machinery of civil engineering and construction can be reduced. It will be possible. The foamed synthetic resin block of the present invention is used for civil engineering and / or construction applications, sea lake water surface floating body applications, etc., and then by removing the surface material,
The foamed synthetic resin block that prevents or reduces surface contamination, pollution, damage, and damage can be taken out and properly cut into the required size for reuse. Alternatively, after removing stains on the surface material by washing such as washing with water without removing the surface material, the foamed synthetic resin block covered with the surface material can be cut as it is to a size necessary for reuse.

Further, in the present invention, since the foamed synthetic resin block is protected by the surface material and further by the reinforcing material, it is possible to prevent or reduce the contamination of the block surface by removing or cleaning the surface material. It is possible to satisfactorily cut into a size required for reuse without being hindered by contamination due to heat generated by energizing a commonly used nichrome wire. As described above, in the present invention, the foamed synthetic resin block is used for a temporary road or the like in which treatment after removal is particularly problematic, and when cut and reused, damage to the block is small,
Since the amount of the block to be discarded can be small, the resources can be utilized to the maximum. In particular, when a foamed synthetic resin block of the size for embankment is used and then cut and reused for construction purposes, it can be reused very efficiently, so that the cost reduction effect is remarkable. Therefore, the foamed synthetic resin block of the present invention can not only be used for temporary roads, etc., which have not been practically realized until now, but can also contribute extremely effectively to effective use of resources.
