〔産業上の利用分野〕
この発明は中空板体を用いて擁壁、特に垂直擁壁を構築
する方法にかかわる。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of constructing a retaining wall, particularly a vertical retaining wall, using hollow plates.
従来、コンクリートの擁壁を構築するには型枠を組み立
て、配筋をしてコンクリートを打設するか、或いは、肉
厚の重力コンクリートブロックを鉄筋で連結しながら積
み上げてきた。Conventionally, concrete retaining walls have been constructed by assembling formwork, arranging reinforcement, and pouring concrete, or by stacking thick gravity concrete blocks connected with reinforcing bars.
〔発明が解決しようとした、問題点
〕従来の方法は前者によれば型枠の組み立てが面倒であ
り、工期も長い。後者によれば重量の大きいブロックの
積み上げ作業と鉄筋の連結作業が面倒であった。[Problem that the invention seeks to solve] According to the former method, assembling the formwork is troublesome and the construction period is long. According to the latter, stacking heavy blocks and connecting reinforcing bars were troublesome.
この発明はこのような問題点を解決するために、一般に
石綿補強のセメント押出し成形による中空板体を用い、
板体側面の集合が擁壁面となるように、多数の中空板体
の側面（側縁面）を外側に向けて、縦に、ないし横積み
にして重ね合わせて設置するものである。In order to solve these problems, this invention generally uses a hollow board made of asbestos-reinforced cement extrusion,
A large number of hollow plates are stacked vertically or horizontally, stacked one on top of the other, with the side surfaces (side edges) facing outward, so that a collection of the side surfaces of the plates forms a retaining wall surface.
このように構築すると中空で軽量な中空板体を設置する
だけでよいから、施工は簡単である。When constructed in this way, the construction is simple because it is only necessary to install a hollow, lightweight hollow plate.
通常の擁壁が必要とした、数十センチの厚みのある中空
板体は生産が難しいが、この方法によれば、擁壁の厚さ
は中空板体の幅であるから、生産は極めて容易である。It is difficult to produce a hollow plate with a thickness of several tens of centimeters, which is required for a normal retaining wall, but with this method, the thickness of the retaining wall is the width of the hollow plate, so production is extremely easy. It is.
又、中空板体を側面を外側にして使用すれば擁壁の力は
中空板体の幅方向に働くので、中空板体の対抗力は大き
い。Furthermore, if the hollow plate is used with the side surfaces facing outward, the force of the retaining wall will act in the width direction of the hollow plate, so the opposing force of the hollow plate will be large.
又、押出し成形板は一般の鋳型成形と違い、長さが数メ
ートルの長尺ものが生産できるので、縦に使用した場合
一本もので継目なく構築が可能なので丈夫な擁壁ができ
る。Also, unlike general mold molding, extrusion molded plates can be produced in long pieces several meters long, so when used vertically, they can be constructed seamlessly as a single piece, creating a durable retaining wall.
〔実施例１〕
第１図に示すように、石綿補強のセメントを押出し成形
により、中５０口、厚さ１５ｃｍ、長さ３〜５ｍで、両
表面には巾Ｉ Ｑ ｃｍ、深さ３ａｎの縞状の凹凸１を

面が同調しており、互いに嵌合できるように構成されて
いる。側面３は擁壁面を構成するので、肉厚に構成し、
押出し成形の段階でロールによる模様付けを施しておく
。[Example 1] As shown in Fig. 1, asbestos-reinforced cement is extruded to form 50 holes, 15 cm in thickness, and 3 to 5 m in length, with a width of IQ cm and a depth of 3 ann on both surfaces. A hollow plate body 2A provided with striped irregularities 1 is formed. The surface and back surfaces of these projections and recesses are aligned so that they can fit into each other. Side 3 constitutes a retaining wall surface, so it is made thick,
A pattern is applied using rolls during the extrusion molding stage.
このような中空板体を用いて垂直擁壁を施工するには、
第２図に示すように、擁壁を構築する地盤に基礎コンク
リート４を打設する。基礎コンクリートは中空板体の幅
の分だけ掘り下げておく。中空板体を側面の模様付き面
を外側に向け、板体を縦にして重ね合わせるように次々
と建てる。縞状の凹凸は互いに嵌合させる。To construct a vertical retaining wall using such hollow plates,
As shown in Figure 2, foundation concrete 4 is placed on the ground where the retaining wall will be constructed. The foundation concrete is dug down to the width of the hollow plate. Hollow boards are built one after another, with the patterned sides facing outward, and the boards stacked vertically. The striped concave and convex portions are made to fit into each other.
適宜の個所で、板体と板体の間に第３図に示すような、
薄鋼板からなり、縞状凹凸に引っ掛かるようにＬ字状に
屈折し、端部には多数の取付孔５を付設置した長尺の取
付金具６を挟み込む。As shown in Figure 3, between the plates at appropriate locations,
It is made of a thin steel plate, is bent into an L shape so as to be caught on striped irregularities, and a long mounting bracket 6 with a large number of mounting holes 5 is inserted at the end.
第４図に示すように、この垂直擁壁７の背面には盛土８
を行うが、盛土の安定を計るために、盛土の中には水平
方向に丈夫なプラスチックネット９を層状に敷設する。As shown in Fig. 4, an embankment 8
However, in order to ensure the stability of the embankment, strong plastic nets 9 are laid horizontally in layers within the embankment.
ネットの擁壁側の端部は、板体に挟持しである取付金具
６の取付孔５にフックなどを用いて取付け、擁壁と連結
する。The end of the net on the retaining wall side is attached to the attachment hole 5 of the attachment fitting 6 held between the plates using a hook or the like, and connected to the retaining wall.
引張強度の大きいプラスチックネットを用いると、ネッ
トは盛土との摩擦により引抜き抵抗が働くので、擁壁が
ネットによって引っ張られ倒れ難くなる。一方、盛土は
層状に敷設されたネットにより、補強されるので円弧滑
りなどが発生し難くなる。これらの相乗効果により、こ
の発明による擁壁は極めて安定した構造を有する。If a plastic net with high tensile strength is used, the net will exert pull-out resistance due to friction with the embankment, making it difficult for the retaining wall to be pulled by the net and fall down. On the other hand, the embankment is reinforced with a layered net, making it difficult for arcuate sliding to occur. Due to these synergistic effects, the retaining wall according to the present invention has an extremely stable structure.
尚、中空板体の中空部等には適宜コンクリート・モルタ
ル・土などを充填しておいてもよい。Note that the hollow parts of the hollow plate may be filled with concrete, mortar, soil, etc. as appropriate.
垂直でなく、若干の傾斜をもった擁壁を構築する場合に
は、基礎コンクリートに傾斜を付けるとか、中空板体の
端部の角度を予め傾斜角度に合わせて切断しておくこと
などにより、容易に実現可能である。When constructing a retaining wall that is not vertical but has a slight inclination, it is best to slope the foundation concrete or cut the end of the hollow plate to match the inclination angle in advance. It is easily achievable.
曲面擁壁を構築する場合には、第５図に示すように、側
面の厚さの異なる、断面形状が扇形の中空板体２Ｂを準
備し、これを重ね合わせて内曲面・外曲面に対応する。When constructing a curved retaining wall, as shown in Fig. 5, hollow plates 2B with different thicknesses on the side surfaces and fan-shaped cross sections are prepared, and these are overlapped to correspond to the inner and outer curved surfaces. do.
尚、中空板体は表面に溝状の凹凸があることが望ましい
が、必須ではなく、表面の平坦な板体でもこの発明によ
る擁壁の構築は可能である。Although it is desirable that the hollow plate has groove-like irregularities on its surface, it is not essential, and the retaining wall according to the present invention can be constructed using a plate with a flat surface.
又、中空板体はセメント製品が望ましいが、必ずしも押
出し成形板に限定されることなく、例えば、スパンクリ
ートなどでもよい。Furthermore, although the hollow plate is preferably a cement product, it is not necessarily limited to an extrusion molded plate, and may be made of, for example, spuncrete.
