【発明の詳細な説明】 〔産業上の利用分野〕 本発明は複数の壁面パネルを積層して構成された壁体の
背面に補強材を連結し、盛土してなる土留擁壁に係り、
特に壁体の変形が少なく、かつ施工性に優れた土留擁壁
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a soil retaining wall formed by embedding earth by connecting a reinforcing member to the back surface of a wall body formed by laminating a plurality of wall panels.
In particular, the present invention relates to a retaining wall for retaining soil which has little deformation of the wall body and is excellent in workability.
この種の土留擁壁として、従来、帯状補強材やグリッド
を壁体の背面に連結し、盛土してなる補強土擁壁が知ら
れている。As a soil retaining wall of this type, conventionally, a reinforced soil retaining wall is known in which a belt-shaped reinforcing material and a grid are connected to the back surface of a wall body to embank.
これらの補強土擁壁は補強材を盛土の転圧層中に埋設し
て構成されるが、盛土の圧縮に順応できるように、壁面
パネル間にクッション材を挾着する等、壁面パネルにも
可撓性を付与する必要がある。These reinforced soil retaining walls are constructed by embedding a reinforcing material in the compaction layer of the embankment, but also on the wall panels, such as by attaching a cushion material between the wall panels to accommodate the compression of the embankment. It is necessary to give flexibility.
しかし、これらは壁面パネル間へのクッション材の使用
により壁体の変位が大きく、かつ施工時の壁体組立の際
に仮設材を用いて壁面パネルを一時的に直立させたり、
上下の壁面パネル間にくさびを打ち込んだり等の必要が
あり、このため施工が非常に煩雑になり、また、盛土の
転圧によって補強材に生じる引張力が増大し、このため
壁体が盛土側に傾斜してしまう。However, the displacement of the wall is large due to the use of the cushioning material between the wall panels, and the wall panels are temporarily erected by using temporary materials during the wall assembly during construction,
It is necessary to drive a wedge between the upper and lower wall panels, which makes the construction very complicated, and the tensile force generated on the reinforcing material by the rolling compaction of the embankment increases. Will tilt to.
さらに、補強材として波状に曲がった棒状補強材、ある
いは一本の直線状縦棒に複数本の横棒をそれぞれ該縦棒
と交差、並列し、固着させて構成される補強材を用い、
これらをそれぞれ壁体の背面に連結し、盛土してなる土
留擁壁も知られている。(特開平1-151616号公報参
照)。Furthermore, as a reinforcing material, a bar-shaped reinforcing material that is bent in a wave shape, or a reinforcing material that is configured by fixing a plurality of horizontal bars to one straight vertical bar by crossing, juxtaposing, and adhering to each vertical bar,
There is also known a soil retaining wall which is constructed by embedding earth by connecting these to the back of the wall. (See Japanese Patent Laid-Open No. 1-151616).
しかし、前者の場合、補強材が波状に曲がっているの
で、盛土の転圧による圧縮や、土層の下方への移行によ
り補強材が延びて壁体が前面に押し出されてしまい、こ
のため壁体の変形が大きい。However, in the former case, since the reinforcing material is bent in a wavy shape, the reinforcing material extends due to compression due to rolling compaction of the embankment and downward movement of the soil layer, and the wall body is extruded to the front surface. Deformation of the body is large.
また、後者の場合、複数本の横棒の存在のため、転圧時
の圧縮や土層の下方への移行の際に補強材に過剰の引張
応力が生じ、補強材が破断したり、壁体が盛土側に傾斜
したり等、前述と同様に壁体の変形が大きい。In the latter case, because of the existence of multiple horizontal bars, excessive tensile stress occurs in the reinforcing material during compression during rolling or when the soil layer moves downward, and the reinforcing material breaks or the wall Similar to the above, the wall body is largely deformed such that the body is inclined toward the embankment side.
そこで、本発明の目的は補強材に応力集中が生じにく

業性が向上され、上述の公知技術に存する欠点を改良し
た土留擁壁を提供することにある。Therefore, the object of the present invention is to prevent the concentration of stress on the reinforcing material, and to reduce the deformation of the wall body, the workability is improved further workability is improved, the soil retaining wall which has improved the drawbacks existing in the above-mentioned known technology. To provide.

る。The reinforcing material connected in this way can move downward by the gap of the stop plate due to the contraction of the cushion material even if it is compressed during rolling or moves downward in the soil layer. Therefore, the reinforcing member is not broken, and the wall body is not deformed such that the wall body is inclined toward the embankment side, so that the wall body is stabilized. For this reason, when stacking the wall panels, upper and lower lateral groove and vertical groove corresponding to each other are provided on both end surfaces of the wall panels which are vertically overlapped with each other, and a stopper plate of a reinforcing member is fitted so as to straddle the upper and lower horizontal grooves, and The wall is constructed by simply stacking the tip of the reinforcing material along the vertical groove filled with the cushioning material to build a wall body, which does not require temporary materials as in the past and is easy to construct and easy to work with. Be improved. It is also possible to make fine adjustments so that the position of the reinforcing material matches the height of the embankment surface during construction.
