【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、道路や地盤の超軽量盛土施工方法に使用する
盛土用発泡樹脂ブロック及びその製造方法に関する。TECHNICAL FIELD The present invention relates to a foamed resin block for embankment used in an ultralight embankment construction method for roads and ground, and a method for manufacturing the same.
埋め立て地や軟弱地盤に道路等の施設を構築する場合に
問題となるのは地盤沈下と土圧の問題である。地盤沈下
は、土が圧力を受けて圧縮するために起きるものであ
り、その上に盛る盛土の重量も重大なファクターとな
る。When substituting facilities such as roads in landfills and soft ground, problems with land subsidence and earth pressure are problems. Ground subsidence occurs because the soil is pressed and compressed, and the weight of the embankment above it is also a significant factor.
土の密度は、一般的には1.7t/m3であるので、1mの厚さ
の盛土を行うと、地盤には単位面積当たり1.7tの荷重が
かかり、これが地盤沈下の要因となる。また、土圧は土
の重量に関連して、高く盛土すれば、大きな土圧が発生
する。The density of soil, since in general is 1.7t / m 3, when performing the fill thickness of 1 m, the ground load is applied 1.7t per unit area, which is a factor of subsidence. Also, the earth pressure is related to the weight of the soil, and if the earth is filled up high, a large earth pressure is generated.
このように、従来の工法においては、盛土の重量が重い
ために、軟弱地盤等における地盤沈下及び土圧増大の問
題があった。As described above, in the conventional construction method, since the weight of the embankment is heavy, there are problems of ground subsidence and an increase in earth pressure in soft ground.

盛土重量の著しい減少及びこれに伴う地盤沈下の抑制及
び土圧の軽減を達成することが可能となった。In order to solve such conventional problems, the present applicant previously invented a method for constructing a retaining wall using an ultralight material containing a foamed resin (Japanese Patent Application No. 60-285197). By this method,
It has become possible to significantly reduce the weight of the embankment, control the ground subsidence, and reduce the earth pressure.
この先に提案した工法においては、発泡樹脂ブロックを
大量に使用するため、ブロックの材料として新材を使用
した場合、コストがかなり高くなるという問題がある。Since the foaming resin block is used in a large amount in the method proposed previously, there is a problem that the cost becomes considerably high when a new material is used as the material of the block.
本発明は、このような問題点に鑑みてなされたものであ
り、多量に廃棄されている包装用等の発泡樹脂を利用す
ることにより、前記ブロックの低コスト化とともに省資
源化を図ることを目的とする。The present invention has been made in view of such problems, and by using a foaming resin for packaging or the like that is discarded in large quantities, it is possible to reduce the cost of the block and save resources. To aim.
この目的を達成するため、本発明の盛土用発泡樹脂ブロ

構造となっている。FIG. 1 shows an example of the structure on the cut surface when a part of the foamed resin block for embankment of the present invention is cut. As can be seen from this figure, a newly foamed bead foam part 2 is filled around the old foamed resin small piece 1 to form an integrated structure.
本発明においては、前記の構成にてなる発泡樹脂のブロ
ックを地盤に敷き詰め、またその上に該ブロックを積層
することにより所定の高さまでのブロック層を形成し、
その上に覆土をして所定の高さの盛土を行う。In the present invention, a block of foamed resin having the above-mentioned structure is laid on the ground, and a block layer up to a predetermined height is formed by laminating the block on the ground,
Cover the ground with soil and embank it to a specified height.
発泡樹脂、例えば発泡スチロールの密度は0.02t/m3であ
るので、土の1.7t/m3と比較して格段に軽量の盛土を行
うことができる。Foamed resin, for example, styrofoam density since it is 0.02 T / m 3, it is possible to perform a much lighter embankment compared to 1.7t / m 3 of soil.
以下、本発明を、実施例に基づいて具体的に説明する。 Hereinafter, the present invention will be specifically described based on Examples.
本発明において使用する発泡樹脂としては、一般的な発
泡スチロールを用いることができる。As the foamed resin used in the present invention, general polystyrene foam can be used.
