[0008]

Embodiments of the present invention will be described with reference to the drawings. In the retaining wall construction method according to the embodiment of the present invention, one end of a fixing fixing member such as a steel bar is fixed to a foundation block that is cast at a slope of a landslide or a falling rock slope, and is provided in advance in a stacking direction. A single panel made of a concrete plate or a steel plate provided with a through hole is stacked while penetrating the fixing member through the through hole, and the fixing panel is tensioned to fix the single panel to the base block. A single panel is placed transversely to the slope, and air mortar or concrete is cast between the slope and the retaining wall made of the formed single panel to integrate the retaining wall and the slope, It can form a retaining wall with sufficient strength at a safe and low cost, and can permanently protect a landslide or a falling rock slope.

Further, in the retaining wall construction method according to the embodiment of the present invention, the fixing panel is piled up on the single panel of the retaining wall formed by the above method while further penetrating the fixing panel through the through hole. It is to be fixed to a single panel that has been fixed in tension, the single panel is similarly arranged transversely to the slope, and an air mortar or a mortar is placed between the retaining wall consisting of the formed single panel and the slope. Concrete is cast and the retaining wall and the slope are integrated. Repeat this construction work, stacking and fixing single panels continuously in the vertical and horizontal directions with respect to the slope, constructing the retaining wall integrated with the slope to the predetermined height, and permanently protecting the landslide or rockfall slope Is what you do.

[0010] Air mortar or concrete is cast between the slope and the single panel to achieve integration, but a lock bolt is attached in advance to prevent rock from falling on the slope, and slip and rock fall are prevented. For this reason, it is possible to fix the retaining wall by fixing the permanent anchor, or to make the retaining wall strong by using both the lock bolt and the permanent anchor.

Next, an outline of a retaining wall (permanent formwork for slope embankment) formed by the retaining wall construction method according to the embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional explanatory view showing a schematic cross section of a retaining wall constructed on a rockfall slope according to an embodiment of the present invention, and FIG. 2 is a landslide / rockfall method according to an embodiment of the present invention. It is sectional explanatory drawing which shows the schematic cross section of the retaining wall constructed with respect to the surface. The difference between FIG. 1 and FIG. 2 is that in FIG. 1, a plurality of lock bolts 6a for rock fall prevention are attached to the slope, but in FIG. 2, permanent locks are used instead of the lock bolts 6a. The anchor 6b is fixed, and the concrete outer wall 2 is fixed in tension on the side of the slope.

As shown in FIG. 1, a plurality of lock bolts 6a are previously attached to a slope (rock A) to prevent falling rocks, and the base block 1 is fixed to the bottom of the slope by an anchor member 5. ing. Here, the anchor member 5 is a permanent anchor that is inserted and fixed in a vertical direction with respect to the horizontal ground (bottom), and is tensioned via the base block 1 to be integrally fixed to the rock A on the horizontal ground. Have been.

An end of the fixing member 3 is embedded in the base block 1. Specifically, a part of a fixing fixing member (for example, a PC steel rod) is embedded in the base block 1 and the other end is protruded, and a PC steel rod or the like is attached to the protruding end to fix the fixing member. The member 3 is formed. The fixing members 3 are stacked and added together according to the vertical length of the concrete outer wall (single panel) 2, and finally become longer than the vertical length of the stacked single panel 2. .

The fixing member 3 for fixing is made of, for example, a screw-joint deformed steel rod for installing a precast, and is axially mounted on the lowermost step (specifically, the first step of a plate 3b described later) of the concrete outer wall (single panel) 2. Is what you do. The fixing member 3 for fixing is not limited to a screw-joint deformed steel bar,
A high-strength steel material suitable for applying a prestress, such as a C steel rod, a PC steel wire, or a PC steel stranded wire, may be used.

Further, in order to assemble and dispose the fixing fixing member 3 reliably and to increase the shear strength and the compressive strength of the base block 1, the base end side is wound with a hoop reinforcing bar 3c and embedded in the base block 1. Supported.

The concrete outer wall (single panel) 2 is made of precast concrete or steel plate, and has a through hole 2a through which the fixing member 3 penetrates in the stacking direction. In the example according to the present embodiment, through holes 2 a are provided at two positions on the left and right of the single panel 2. In addition, the single panel 2 is made of a material such as concrete having excellent watertightness and strength, and may have an outer surface (front surface) as shown in FIG. Specifically, a decoration surface such as a horizontal stone pattern is appropriately formed on the front surface side, and the entire surface is configured by a mold frame exhibiting a geometric pattern.

Then, the fixing member 3 is passed through the through hole 2a of the single panel 2, and the plate and the nut (connection nut) are formed.
The fixing member 3 is tensioned with respect to the single panel 2 to fix the single panel 2 to the base block 1. Due to this tension, the single panel 2 becomes independent in the vertical direction. Thus, by tensioning the fixing member 3, the single panel 2 has the same function as the prestressed concrete. That is, the fixing member 3 serves as a PC steel material,
Due to the tension, a compressive force is applied to the unit panel 2 in advance to cancel the tensile force generated inside when a load is received. Thereby, since the single panel 2 is strong in tensile force and can be thin, the weight can be reduced, the material can be saved, the work can be simplified, and the construction can be performed at low cost.
