Description of the Related Art Conventionally, as a structure for embankment of this kind, which is installed for protection of slopes in mountains, valleys, roads, residential areas, riverbanks, etc. and for greening, the inside is filled with earth and sand, rubble and the like. It is known that basket blocks (gabions) containing objects are stacked in multiple stages along the slope of a slope. Such a structure has a cage block made of wire mesh and is packed with stones inside, so it excels in water permeability and can quickly drain moisture in the back soil. Not only is it possible, but the friction between the soil and the back soil is large, and the soil retaining effect that suppresses landslides is also excellent.

おそれがあった。However, in order for the above-mentioned structure to exert an effective retaining effect on the entire back soil behind it, a plurality of stacked car blocks may cause partial displacement or dropping out of the cage blocks. It is important that they are installed so that mutual positional relations can be maintained stably without occurrence. In other words, if some cage blocks locally displace or fall off, not only will it cause other cage blocks to displace, but also local sediment runoff will occur from that part, This is because the structure may be deformed by increasing the displacement of the cage block, and eventually the entire structure may collapse from that portion. However, in this type of conventional structure, a plurality of cage blocks are simply piled up and down, so that each cage block can freely move independently, and local displacement due to subsidence of the ground or the like. And this may lead to collapse of the structure.

落するといったおそれがある。[0004] A method of connecting the stacked car blocks to each other or individually fixing the car blocks to a slope with anchor bolts has been proposed. However, in the former method of directly connecting the cage blocks, the other cage blocks are also misaligned by being dragged by the misaligned cage blocks, and the structure is easily bent and broken at that portion, and the entire cage block is not necessarily stable. It does not lead to transformation. In addition, the latter method of fixing each basket block individually with anchor bolts is opposite to the former method, because the linkage between cage blocks is weak,
There is a risk that some basket blocks will shift or fall off at each anchor bolt.

築堤用構造体を提供することにある。The main problem of the present invention is that a plurality of stacked car blocks can always maintain a stable positional relationship with each other, such as local displacement or collapse of the car blocks. It is an object of the present invention to provide a structure for embankment which is hard to generate, and which is strong and has a high retaining effect.

And a fixing earth pressure resistance member having a vertical length extending over a plurality of cage blocks and being buried substantially in parallel with the slope in the back soil behind the corresponding cage block. Are connected to each other by a connecting member having both ends fixed to a fixed point of the cage block and the earth pressure resistance member, whereby a plurality of cage blocks are fixed to the slope with a common earth pressure resistance member. An embankment structure is provided.

等を生じないため、堅牢で土留効果が非常に高い。In the structure having the above-described structure, the stacked basket blocks are supported by the common earth pressure resistance member via the connecting member, so that the cage block is centered on the fixed point on the earth pressure resistance member side. By merely moving within a certain range, some of the objects alone do not largely displace or fall off, and the overall positional relationship between them is hardly changed. Therefore, the positional relationship between the cage blocks can be always maintained stably, and there is no local displacement or dropping of the cage blocks. Therefore, the cage blocks are robust and have a very high retaining effect.

It is in position. Thus, when the cage block sinks due to subsidence or outflow of the ground, the downward component force of the pulling force acting on the earth pressure resistance member via the connecting member pushes the earth pressure resistance member into the ground. As a result, the supporting force of the earth pressure resistance member is further strengthened, and the support of the basket block is rather stabilized. In the present invention, the upper and lower basket blocks can be interconnected.

に定点５ａを設けることもできる。The connecting member 5 for connecting the basket blocks 2 and the earth pressure resistance member 3 may be made of a flexible material such as a wire rope or a non-flexible material such as a metal rod. ,
Both ends of the connecting member 5 are rotatably connected to the cage blocks 2 and the earth pressure resistance member 3 at fixed points 5a and 5b by bolts or other metal fittings. When the connecting member 5 made of a flexible material is used, it is stretched in a tensioned state. In this case, the position of the fixed point 5a at which the connecting member 5 is connected to the basket block 2 may be at the upper end of the back surface of the basket block 2 or at the lower end as shown in the figure, or in the middle thereof. Or a plurality of these points. The fixed point 5a may be provided at an appropriate position on the upper surface, the bottom surface, or the front surface.

で連結されている。The position of the fixed point 5a on the side of the car block 2 and the position of the fixed point 5b on the side of the earth pressure resistance member 3 may be the same height or one of them may be higher than the other. Preferably, the fixed point 5a on the cage block 2 side is at the same height as the fixed point 5b on the earth pressure resistance member 3 side or at a position lower than that. The reason for this is that, as shown by a chain line in FIG. 1, when the position of the fixed point 5a on the side of the cage block 2 is low when the cage block 2 is displaced due to subsidence of the ground or the like, the earth pressure resistance member 3 side The supporting force of the connecting member 5 always acts on the cage block 2 with the fixed point 5b as a fulcrum, and the cage block 2 is drawn to the earth pressure resistance member 3 side, so that the cage block 2 moves outward of the structure 1A. This is because displacement can be reliably prevented. Thus, the basket blocks 2 of each stage are connected in the same manner by the connecting members 5 to respective corresponding positions on the common earth pressure resistance member 3.

も崩れることがない。In the structure 1A having the above structure, the stacked basket blocks 2 are supported by the common earth pressure resistance member 3 through the connecting member 5, so that Only in the range along the circular arc having the radius of the length of the connecting member 5 with the fixed point 5b as the center, some of the cage blocks 2 are largely displaced by themselves, or may be outside the structure 1A. Even if the ground subsidence or the outflow of the soil occurs partially, the cage block 2 in that part shifts in the direction of being attracted to the earth pressure resistance member 3 without being displaced or falling off. On the contrary, since the soil is pressed down, further outflow of soil can be prevented, and the overall positional relationship between the cage blocks does not collapse.

て強固なものとなる。Therefore, the positional relationship between the cage blocks can be always maintained stably, and there is no local displacement or drop-off of the cage block 2, so that the cage block 2 is robust and has a very high retaining effect. Further, when each cage block 2 sinks due to subsidence or outflow of the ground, a tensile force acts on the earth pressure resistance member 3 via the connecting member 5, but the component force is inclined. , The earth pressure resistance member 3 is pressed more strongly in the ground, and the buried state is further stabilized, so that the support force of the cage block 2 is rather strong.

It is connected to the corresponding earth pressure resistance member 3. In this case, the ends of the two cage blocks 2 and 2 located on both sides of the boundary 7 may be connected by individual connecting members, but the ends of the two cage blocks 2 and 1 are connected by one connecting member 5.
