[Means for Solving the Problems]
Y-shaped pressure receiving plates are arranged upside down, hexagonal auxiliary members are interposed between the Y-shaped pressure receiving plates at the same stage, and trapezoidal auxiliary members are interposed between the outer legs of the left and right Y-shaped pressure receiving plates. This is a slope stabilization method in which the next-stage Y-shaped pressure receiving plates are arranged in an inverted manner to form a honeycomb as a whole.
Y-shaped pressure-receiving plates are arranged upright, trapezoidal auxiliary members are interposed between the uppermost pressure-receiving plates, hexagonal auxiliary members are installed on the Y-shaped legs, and the next-stage Y-shaped pressure-receiving plates Is a slope stabilization method in which the slabs are arranged in an upright shape and have a honeycomb shape as a whole.
This is a slope stabilization method in which a polygonal auxiliary member is interposed between units in which upright and inverted Y-shaped pressure receiving plates are combined to form a tortoiseshell pattern.
This is a slope stabilization method in which a polygonal auxiliary member is arranged between units in which Y-shaped pressure receiving plates are horizontally and symmetrically combined to form a turtle shell pattern.

DETAILED DESCRIPTION OF THE INVENTION
The pressure-receiving plate 1 is made of concrete and has a Y-shaped planar shape. The length of one side of the Y-shape is 2-3 m, the center thickness is 400-600 mm, and the end thickness is 250-350 mm. The thickness is thin. A concave portion is formed in the central portion of the pressure receiving plate 1, and a ground anchor insertion hole penetrating the lower surface and a grout filling hole are formed at appropriate positions on each side on the bottom surface of the concave portion. A plurality of grooves are provided on the bottom surface of the pressure receiving plate 1 to increase the adhesion and stabilize the pressure. Furthermore, an appropriate number of suspension bolts are provided for lifting work during construction.

【The invention's effect】
According to the present invention, a honeycomb pattern or a turtle shell pattern can be formed on a slope by using an auxiliary member for the Y-shaped pressure receiving plate. In addition, the distance between the legs of the pressure plate is reduced compared to the slope stabilization method using a conventional pressure plate such as a cross, and the shoulder is pressed by the Y-shaped pressure plate, making it difficult to collapse. .
