Abstract
PURPOSE: To prevent the collapse of soil with high operation efficiency, by forming cut beams, which are provided with contact surfaces making up divided arcs in the upper and lower directions toward the outside, so that the cut beams continually maintain tangent contact with sheathing master pillars.
CONSTITUTION: Circular arc material assemblies 39, 39 and a cut beam assembly, which both sides are equipped with mounting plates, are unified through mounting flanges 34, 36 of the cut beam assembly, which face each other. A horizontal distance D between pressure contact circular arc surfaces, the longest length of the cut beam, is obtained by adjusting the total length by the operation of a turnbuckle in value gained by subtracting the sum total 2W of the thickness of left-and-right pressure contact ditch materials from an inner surface horizontal distance l of master pillars, which face each other. A plurality of cut beams that curvature radii in the vertical directions of the circular arc surfaces of both ends are (l-2W)1/2 are installed in parallel between mutual cut beams between a pair of master pillars, which face each other. Thus, the collapse of soil is prevented because the cut beam side causes rolling contact with the sinking of a sheathing plate.
