CONCRETE RETAINING WALL
PROBLEM TO BE SOLVED: To solve the problem of strongly desiring its solution, since a conventional L-shaped retaining wall has a defect of easily moving by being pushed out to the road side when the sliding effect is caused by earth pressure in an inclined part with the lapse of long time, has a defect of forming a crack by causing stress concentration in a joining part since an inclined bottom plate part is formed at an angle to a vertical part, and also has a defect of becoming long and uneconomical and being difficult in its installation since a taper pin for connecting mutual adjacent retaining walls connect mutual central ribs.SOLUTION: An R bottom plate type retaining wall provides the R bottom plate type retaining wall having a vertical wall part and an R-shaped bottom plate part, and constituted so that a support part is provided in a lower part of the R bottom plate type retaining wall, and the R bottom plate type retaining wall is tiltable and easily installed by small force with here as a fulcrum, and a reinforcement forehead part is provided for reducing weight by increasing strength of the whole.SELECTED DRAWING: Figure 1
【課題】 従来のＬ型擁壁は、長期の時間経過とともに、傾斜部が、土圧により、滑り効果が発生し、道路側に押し出され、移動いやすいという欠点が有り、又傾斜底板部が垂直部に対して、角度をもって形成されているため接合部に応力集中を起こし割れ目が出るという欠点や、また、隣接する擁壁同士を連結するテーパーピンが、中央のリブ同士をつないでいるため、長くなり不経済で、その取付が難しいという欠点も有り、その解決が、強く望まれていた。【解決手段】 Ｒ底板式擁壁は、垂直壁部とＲ形底板部を有しており、Ｒ底板式擁壁の下部には、支持部が設けてあり、ここを支点としてＲ底板式擁壁が小さな力で傾動出来、設置しやすいよう構成されており、又全体の強度を増し重量を減少するため、補強額部が設けられていることを特徴とするＲ底板式擁壁を提供する。【選択図】図１
