Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slope stabilization method in which a Y-shaped pressure receiving plate is fixed to a cut slope using a ground anchor to stabilize the cut slope and prevent natural slopes from collapsing and landslides.
[0002]
[Prior art]
The slope stabilization method, as shown in Fig. 5, prevents the landslide by fixing multiple concrete or steel pressure plates with cross-shaped legs to the slope with ground anchors, and stabilizes the slope. To prevent collapse.
Japanese Patent Laid-Open No. 6-346454 describes that a Y-shaped pressure receiving plate is fixed to a slope.
[0003]
[Problems to be solved by the invention]
The present invention proposes an effective slope stabilization method using a Y-shaped pressure receiving plate and an auxiliary member.
[0004]
[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.
[0006]
1 to 4 show a slope stabilization method using a Y-shaped pressure receiving plate 1 and an auxiliary member, and hexagonal or trapezoidal auxiliary members 30 and 31 are interposed between the Y-shaped pressure receiving plate 1. The Y-shaped pressure receiving plates are arranged in a honeycomb shape or a tortoiseshell shape as a whole by performing or placing in place.
In FIG. 1, a Y-shaped pressure receiving plate 1 is arranged upside down, a hexagonal auxiliary member 30 is interposed between the Y-shaped pressure receiving plates 1 and 1 at the same stage, and Y-shaped at the left and right ends. This is a slope stabilization method in which a trapezoidal auxiliary member 31 is interposed on the outer leg of the pressure receiving plate, and the Y-shaped pressure receiving plate 1 of the next stage is arranged upside down to form a honeycomb shape as a whole.
[0007]
In FIG. 2, the Y-shaped pressure receiving plate 1 is arranged upright along the shoulder, and a trapezoidal auxiliary member 31 is interposed between the Y-shaped pressure receiving plates 1 of the same step, This is a slope stabilization method in which a hexagonal auxiliary member 30 is installed between the upright and Y-shaped pressure receiving plates 1 to form a honeycomb shape.
[0008]
FIG. 3 shows a slope in which a trapezoidal auxiliary member 31 or an octagonal auxiliary member 32 is interposed between units in which an upright and an inverted Y-shaped pressure receiving plate 1 are combined to form a tortoiseshell pattern as a whole. It is a stabilization method.
The octagonal auxiliary member 32 may be a hexagonal shape by combining the trapezoidal auxiliary member 31.
[0009]
FIG. 4 shows a slope stabilization process in which trapezoidal or octagonal auxiliary members 31 and 32 are interposed between units in which Y-shaped pressure receiving plates 1 are placed sideways symmetrically to form a tortoiseshell pattern as a whole. Is the law.
The slope stabilization method of the arrangement shown in FIG. 2 and FIG. 3 is such that the distance between the legs of the pressure receiving plate is smaller and the shoulder is Y-shaped pressure receiving plate compared to the conventional method using a cross-shaped pressure receiving plate. There is an advantage that it is pressed and is difficult to collapse.
[0010]
【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. .
