EARTH RETAINING TIMBERING STRUCTURE
To provide an earth retaining timbering structure capable of suppressing downward deflection occurring at a center in a longitudinal direction of a cutting beam with a simple structure and securing a long scale of the cutting beam.SOLUTION: An earth retaining timbering structure includes at least a pair of wales and one or a plurality of cutting beams 3 arranged in a longitudinal direction so as to bridge between the pair of wales. The cutting beam 3 is disposed so as to have a substantially arcuate shape which is convex upward as a whole at least at the time of installation. When connecting the plurality of cutting beams 3, a shim plate 7 for keeping the spacing between upper end edges of end faces 31 wider than the spacing between lower end edges of the end faces 31 is inserted into at least a part between the end faces 31 of the cutting beams 3.SELECTED DRAWING: Figure 1
【課題】シンプルな構造で切梁の長方向中央に生じる下方への撓みを抑制し、切梁の尺を長く確保できる山留支保工構造を提供する。【解決手段】山留支保工構造であって，少なくとも一対の腹起しと，一対の腹起しの間に架け渡すように長手方向に配置された一又は複数の切梁３とを備え，切梁３は，少なくとも設営時に全体で上向きに凸となる略弧状を呈するように配置されている。複数の切梁３を連結する場合，切梁３の端面３１同士の間の少なくとも一部には，当該端面３１の上端縁同士の間の間隔を当該端縁３１の下端縁同士の間の間隔よりも広く保つためのシムプレート７が差し込まれる。【選択図】図１
