Conventionally, retaining walls have been formed using a steel material in which connecting joints 4 are provided at both ends of a cross-sectional groove steel 5 as shown in FIG. 1, or an equilateral H-shaped steel 6 as shown in FIG. It is known that a retaining wall is formed using a steel material in which connecting joint portions 4 are provided at both ends of each flange 7. Those using equilateral H-shaped steel 6 are groove steel 5.
The rigidity per unit weight ratio is higher than that of the equilateral H-shaped steel 6, and it is economical because thin-walled steel can be used to obtain the necessary rigidity.
6, if the retaining wall is non-linear in cross section or has corners, when forming these, the flange 7 of the adjacent equilateral H-shaped steel 6 is used as shown in Fig. 3. There was a problem in that the retaining walls were in the way and could not be connected to each other, and therefore it was impossible to form retaining walls that were non-linear or had corners. Also,
When constructing a retaining wall by arranging equilateral H-beams 6 horizontally in the ground, the webs 8 of each steel material will partition the ground, and the bond between the ground on both sides of the web 8 or the bonding force between the steel material itself and the ground will be reduced. There was a problem that I couldn't get enough.

を設けてもよい。 The present invention will be explained in detail below based on examples. The steel material 9 used in the present invention has the following configuration.
In other words, one of the flanges of the conventional narrow H-shaped steel is extended to both sides to create a longer flange 1.
It is as follows. Therefore, the longer flange 1 having this extension has a longer width than the shorter flange 2. A connecting joint 4 having a C-shaped cross section, a hook shape, etc. is further provided at the tips of the extensions present at both ends of the longer flange 1. Here, to show a specific example of the steel material 9 for retaining walls of the present invention, in Fig. 5, A = 400 mm, B = 600 mm,
B' = 200 mm, t 1 = 4.5 mm, t 2 = 6 mm, and t 3 = 18 mm, but it goes without saying that the values are not necessarily limited to the above values. However, the wall thickness of the narrow flange is made thicker than the wall thickness of the wide flange as in the above embodiment. web 3
As shown in FIG. 4, trapezoidal through holes 15, one side of which coincides with the joint with the wide flange 1, are provided at regular intervals along the longitudinal direction. Of course, the position and shape of the through hole 15 are not limited to this, and various shapes as shown in FIGS. 8a and 8b can be applied. The mountain retaining wall is constructed using the steel material 9 having the above-mentioned structure. As shown in FIG. (In some cases, a wall is formed by disturbing the earth and sand), when the soil cement column or soil bentonite column 11 is unhardened, the steel material 9 is inserted and the next steel material 9 is engaged using the connecting joint part 4 as a guide. Adjacent steel members 9 are connected to each other by the connecting joint portion 4, and in the same manner, steel members 9 are connected one after another by the connecting joint portion 4. In this way, the retaining wall is A soil cement wall, a soil bentonite wall, or a disturbed earth and sand wall 12, that is, a mountain retaining wall, is formed using steel material 9 as a core material. Here, the steel material 9 serves as a stress member of the retaining wall and also serves as a water stop member by being connected with the connecting joint portion 4, and when the steel material 9 is installed,
Unhardened wall material, such as the above-mentioned soil cement, bentonite, or disturbed earth and sand enters the through holes 15 provided in the web 3 of each steel material 9, and the web 3
The wall materials on both sides are bonded together through the through holes 15 to enhance the bond between the steel material and the wall material. As shown in FIG. 9, in order to increase the buckling strength of the steel material 9, a rib 16 is provided at the joint part of the wide flange 1 with the web 3, or at a part away from this joint part.

As described above, in the present invention, since one flange is wider than the other flange,
Even if the target retaining wall is non-linear or has corners, the narrower flanges of adjacent steel members can be used to create a wider width without interfering with each other, as shown in Figure 7. Flanges can connect horizontally arranged steel members to each other, and the steel members are built continuously in a soil cement wall, soil bentonite wall, or disturbed earth and sand wall formed in the ground so that adjacent steel members are connected to each other. By using the highly rigid scalene H-beam steel as the core material for soil cement walls, soil bentonite walls, disturbed earth and sand walls, etc., it is possible to form mountain retaining walls with strong strength and water-stopping properties. Of course, the wall thickness of the narrow flange is set thicker than the wall thickness of the wide flange, so even though one flange is made narrow, the strength of the narrow flange is The strength of each part of the scalene H-shaped steel can be balanced, and the strength can be stabilized. In addition, in the present invention, since a plurality of through holes are formed in the steel web along the longitudinal direction, when the steel web is erected, the wall material in the ground enters the through holes and the web The wall materials on both sides can be connected through a through hole, and since it is scalene H-shaped steel, when scalene H-shaped steel members are connected with wide flanges, the wall material in the ground will be connected to the web as shown above. The wall materials on both sides of the wall can be connected through a through hole, and the wall materials outside the scalene H-shaped steel can be connected through the ends of the adjacent narrow flanges. This has the advantage of increasing the bonding strength between the wall material and the steel, allowing the construction of a high-strength mountain retaining wall.
