Abstract

<P>PROBLEM TO BE SOLVED: To provide a paving method for forming a pavement excellent in elasticity and herbicidal properties, and easy to re-form. <P>SOLUTION: The paving method is characterized by superposing the pavement which is a combination of an organic layer formed of organic materials derived from plants, and a herbicidal layer formed of a sheet material having imperviousness, on leveled ground surface. Herein the organic layer means a layer formed of materials derived from plants such as straws and wooden chips, and the wooden chips are produced by cutting waste wood into chips. Either the organic layer or the waterproof sheet layer may be laid on an upper side, but when the waterproof sheet layer is laid on the upper side, an asphalt layer, for instance, is preferably laid on the waterproof layer to protect the same. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、整地面の舗装方法に関する。   The present invention relates to a method for paving a leveling surface.

路床整地面には広くアスファルト舗装が採用されている。
しかし、路床整地面に直接アスファルト舗装すると再舗装や再開発時のアスファルト剥離作業が大変であった。
また、舗装面の弾力性に劣る問題もあった。
特開平11−322386号公報には、穀物種子などの草本植物廃棄物を用いた弾性舗装体を開示するが、弾性舗装体が透水性を有するため整地面(路床)から植物が生育してしまう問題があった。
Asphalt pavement is widely used for roadbed leveling.
However, if the asphalt pavement is directly applied to the roadbed leveling surface, the asphalt removal work during re-paving and redevelopment was difficult.
There is also a problem that the elasticity of the pavement surface is inferior.
Japanese Patent Application Laid-Open No. 11-322386 discloses an elastic pavement using herbaceous plant waste such as cereal seeds. However, since the elastic pavement has water permeability, plants grow from the leveling ground (roadbed). There was a problem.

特開平11−322386号公報JP-A-11-322386

本発明は上記技術的課題に鑑みて、弾力性及び防草性に優れ、再施工しやすい舗装方法の提供を目的とする。   In view of the above technical problems, an object of the present invention is to provide a pavement method that is excellent in elasticity and herbicidal properties and is easy to reconstruct.

本発明の技術的要旨は、植物由来の有機物で形成した有機層と、遮水性を有するシート材からなる防草シート層との組み合せからなる舗装体を整地面の上に積層することを特徴とする。   The technical gist of the present invention is characterized in that a pavement made of a combination of an organic layer formed of a plant-derived organic material and a herbicidal sheet layer made of a sheet material having water shielding properties is laminated on a leveling surface. To do.

ここで有機層とは、藁や木材チップといった植物由来のものを用いて形成する趣旨であり、木材チップは廃材をチップにして用いるとよい。
有機層と防水シート層はどちらを上にして積層しても良いが、防水シート層を上にした場合には防水シート層の上に例えばアスファルト層を設けて防水シート層を保護すると良い。
Here, the organic layer is intended to be formed using plant-derived materials such as firewood and wood chips, and wood chips may be used by using waste materials as chips.
Either the organic layer or the waterproof sheet layer may be laminated on top, but when the waterproof sheet layer is placed on top, for example, an asphalt layer may be provided on the waterproof sheet layer to protect the waterproof sheet layer.

請求項2記載の発明の技術的要旨は、整地面の上に藁むしろ材に除草剤を散布して形成した有機層を形成し、有機層の上に防草シート層を形成し、防草シート層の上にアスファルト層を形成することを特徴とする。   The technical gist of the invention described in claim 2 is to form an organic layer formed by spraying a herbicide on the material on the leveling surface, and to form a herbicidal sheet layer on the organic layer. An asphalt layer is formed on the sheet layer.

請求項3記載の発明の技術的要旨は、整地面の上に防草シート層を形成し、防草シート層の上に木材チップを転圧敷設し、木材チップ層に除草剤とアスファルト乳剤との混合乳剤を散布して有機層を形成することを特徴とする。   The technical gist of the invention described in claim 3 is that a herbicidal sheet layer is formed on the leveling surface, a wood chip is laid down on the herbicidal sheet layer, and a herbicide, an asphalt emulsion, An organic layer is formed by spraying the mixed emulsion.

本発明に係る舗装方法においては、遮水性の防草シート層と植物由来の有機層とを組み合せて整地面に舗装することにより雑草の生育を防止し、適度な弾力性を付加することで歩行感を良くし、また、舗装上の人に伝わる(例えば鉄道高架橋からなどの)周囲からの振動を緩和させることが出来る。   In the pavement method according to the present invention, weed growth is prevented by paving on a leveling surface by combining a water-proof grass-proof sheet layer and a plant-derived organic layer, and walking by adding appropriate elasticity. The feeling can be improved and vibrations from the surroundings (for example, from a railway viaduct) transmitted to people on the pavement can be reduced.

有機層を藁むしろ材を用いて形成した場合には、藁むしろ材を形成する藁が整地面にからみ、舗装強度を高めることが出来る。
また、藁むしろ材に散布した除草剤が整地面から雑草が生えるのを効果的に防止する。
In the case where the organic layer is formed by using a material rather than a material, the material forming the material can be entangled with the leveling surface to increase the pavement strength.
In addition, the herbicide sprayed on the wood effectively prevents weeds from growing on the ground.

有機層を木材チップを用いて形成した場合には、木材チップに除草剤とアスファルト乳剤とを混合した混合乳剤を散布することで木材チップ転圧面に飛来した種子が嵌り込み雑草が生えるのを防止し、周囲からの振動を緩和するように作用するので高速道や鉄道高架下、駅前等の舗装すると効果的である。   When the organic layer is formed using wood chips, spraying a mixed emulsion of a herbicide and asphalt emulsion on the wood chips prevents the seeds flying into the wood chip compaction surface from entering and preventing weeds from growing. Since it acts to alleviate vibrations from the surroundings, it is effective to pave on highways, under railway overheads, in front of stations, etc.

整地面21の上に、藁むしろを敷設して藁むしろ層からなる有機層30aを形成し、その上に防草シート層40を形成し、防草シート層40の上にアスファルト層50を形成する。
整地面21は地面をバックフォー等の建機で削り、余分な砂、石を除去し水平に整地する。
藁むしろ層30aは、整地面に除草剤を散布し、藁むしろ材31を複数枚重ねて、整地面21上に敷設する。
その際に水を撒くと藁むしろ材31が整地面になじみやすい。
防草シート層40は、遮水性を有するビニール製等の防草シート材41よりなり、複数枚の防草シート材41を隙間を生じないように藁むしろ層30a上に並べ、ピン材の打ち込みずれを防止する。
次に、防草シートの上にアスファルト層50を形成し、上を車で移動出来るようにしてある。
アスファルト層50は、隙間の少ない密粒ギャップアスファルトを用いて形成して、水を浸透しにくくし、また、飛来種子が嵌りにくいものを用いるとよい。
藁むしろ材31は藁で編んであるため適度に弾力性があり、藁むしろ材31を複数枚を重ねてアスファルト層の下に藁むしろ層30aとして敷設することで、舗装面に適度な弾力性を付加する。

The leveling surface 21 is ground with a construction machine such as a back fork to remove excess sand and stones and level the ground.
Rather, the layer 30 a spreads the herbicide on the leveling surface and lays the material 31 on the leveling surface 21 by stacking a plurality of materials 31.
At that time, if water is poured, the material 31 is more likely to become familiar with the leveling surface.
The weedproof sheet layer 40 is made of a vinyl-proof grassproof sheet material 41 having a water-impervious property, and a plurality of the weedproof sheet materials 41 are arranged on the layer 30a so as not to form a gap, and a pin material is driven. Prevent misalignment.
Next, an asphalt layer 50 is formed on the weedproof sheet so that it can be moved by car.
The asphalt layer 50 may be formed by using dense-gap asphalt with few gaps so as to make it difficult for water to penetrate and to prevent the flying seeds from fitting.
Rather, the material 31 is moderately elastic because it is knitted with a scissors, and it is moderately elastic on the pavement surface by laying multiple layers of the material 31 as a layer 30a under the asphalt layer. Is added.

アスファルト舗装は、ゴムキャタピラのアスファルトフィニッシャーを使うと防草シートが破れるのを防止する。
アスファルト層50の厚さは3cm以上が良い。
アスファルト層50の周縁部は、防草シート層40及び藁むしろ層30aより拡げて周囲の構造物となじませる。
これにより藁むしろ層及び防草シート層が整地面から雑草が生えるのを防止し、アスファルト層が飛来種子にて雑草が生えるのを有効に防止する。
また、アスファルトの下に有機層が存在するので有機層を境にしてアスファルト層が剥がしやすく、舗装面の撤去が容易になる。
Asphalt pavement uses a rubber caterpillar asphalt finisher to prevent the weedproof sheet from breaking.
The thickness of the asphalt layer 50 is preferably 3 cm or more.
The peripheral portion of the asphalt layer 50 is expanded more than the herbicidal sheet layer 40 and the layer 30a, so that it can blend with the surrounding structure.
As a result, the layer and the weed prevention sheet layer prevent weeds from growing on the leveling surface, and the asphalt layer effectively prevents weeds from growing on the flying seeds.
Moreover, since an organic layer exists under the asphalt, the asphalt layer is easily peeled off at the boundary of the organic layer, and the paved surface can be easily removed.
