EARTH RETAINING SUPPORT, SUPPORT REMOVAL METHOD, AND SUPPORT COMPONENT

PROBLEM TO BE SOLVED: To provide an earth retaining support that increases efficiency of earth retaining support removal work, a support removal method, and a support component.SOLUTION: An earth retaining support 1 includes: a plurality of tiers of support parts 3 which comprise a wale 5 horizontally extended along an earth retaining wall 101 and a backfilling material 9 for filling a clearance between the wale 5 and the earth retaining wall 101, and which are arranged in parallel in a vertical direction; and a connection member 11 for vertically connecting the backfilling materials 9 of the support parts 3 in the different tiers. In work for removing the earth retaining support 1, the plurality of connected backfilling material 9 can be continuously recovered by being pulled up from above.SELECTED DRAWING: Figure 1 【課題】土留支保工の撤去作業の効率を向上させる土留支保工、支保工撤去方法、及び支保工部品を提供する。【解決手段】土留支保工１は、土留壁１０１に沿って水平に延在する腹起し５と、腹起し５と土留壁１０１との間隙を埋める裏込充填材９と、を備え鉛直方向に並列して配置された複数段の支保部３と、異なる段の支保部３の裏込充填材９同士を上下方向に連結する連結部材１１と、を備える。土留支保工１の撤去作業では、連結された複数の裏込充填材９を上方から引き上げるようにして連続的に回収することができる。【選択図】図１
