Abstract

PURPOSE: To prevent, as much extent as possible, shearing force from working on connecting parts by a method wherein the structure for connecting parts is so constructed that a banking reinforcement material can turn downward at the connecting parts when the reinforcement material is connected to a wall surface panel and tensile force only works on the connecting parts. CONSTITUTION: A plurality of anchor metals 9, each having continuous connecting parts extending vertically in a bar-like structure, are provided transversely at specified intervals at the rear of a wall surface panel 2. A horizontal connecting bar 5 is inserted through the connecting parts 9a of the anchor metals 9 and connecting rings 3b, each formed at the end of banking reinforcement material 3. Thereby, the banking reinforcement material 3 can be connected to the anchor metals 9 so that it can be moved pivotally in the vertical direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is embedded in an embankment layer,
The embankment reinforcement that supports the wall panel installed at the tip of the embankment layer slides down at the connection with the wall panel following the sinking of the embankment layer, and rotates downward, thereby The present invention relates to a wall structure of a reinforced earth structure that prevents stress concentration at a connecting portion between a panel and an embankment reinforcement and shear fracture of the connecting portion due to the stress concentration.

2. Description of the Related Art Conventionally, the problems to be solved by the invention
As a reinforcing soil structure such as a retaining wall, for example, as shown in FIG. 16, a wall panel 21 made of a precast concrete plate is installed at the tip of the embankment layer 20, and a fixing bracket 22 is provided on the back surface of the wall panel 21. A plurality of embankment reinforcements 23 made of projecting and geotextile in the embankment layer 20 or reinforced grit, steel, etc. are embedded in a plurality of layers, and the embankment reinforcements 23 are fixed to the wall panel 21 via the fixing brackets 22. It is known that it is constructed by connecting it to the back surface of the (the embankment reinforcement 23 is made of steel in the figure).

However, when a geotextile is used as the embankment reinforcement 23, the geotextile is soft and therefore easily displaced following the displacement of the embankment, so that it is less susceptible to stress concentration, but the elongation and displacement are large.
There is a danger that 21 will easily tilt or move, so geotextile is not suitable as a embankment reinforcement that also functions as a fixing member for wall panels, and the tip of the geotextile is mainly caught at the tip of the embankment layer 20. It was common to green the surface of the embankment layer 20.

On the other hand, when reinforcing bar grit or steel material is used as the embankment reinforcing material 23, the reinforcing bar grit or band (hereinafter referred to as "reinforcing bar grit") has a great effect of restraining the embankment, and has a large strength and bending rigidity. Since it is unlikely to stretch or displace, it is excellent as a embankment reinforcing material that also serves as a fixing member for the wall panel 21, but as it is, since it has a large rigidity, it is difficult to follow the displacement of the embankment and is susceptible to stress concentration.
For this reason, it may be broken by the shearing force before the original tensile strength is fully realized.

Therefore, when installing the reinforcing bar grit or the like, it is necessary to have a structure that receives as little shearing force as possible and only pulling force.

The wall panel 21 is usually made of a rigid material such as concrete. On the other hand, the embankment layer 20 is a granular material, which is easily compressed and deformed during rolling. When the embankment layer 20 is compacted, the connection with 23 is subject to relative displacement and is greatly affected by the movement of surrounding soil particles, and may eventually be destroyed.

Further, it is very economical and desirable to use a locally generated material as the embankment for constructing the embankment layer 20, but if the quality of the embankment is poor, the wall surface is easily displaced due to the large compressibility of the soil. Also, as time passes, the wall panel 21
The stress at the connecting portion between the embankment and the embankment reinforcing member 23 changes, and an unpredictable complicated stress is likely to occur at the connecting portion, and the connecting portion is easily broken.

Generally, the displacement of the wall surface is caused by the compression of the embankment layer 20 due to the compressive load and the expansion in the lateral direction, and further, the slack at the connecting portion between the wall surface panel 21 and the embankment reinforcement member 23 during the compaction is increased. , The deformation of the connecting portion caused by the load, the deformation of the embankment reinforcement 23 and the wall panel 21 connected to the embankment reinforcement 23 due to the compression of the embankment layer 20 due to the overload after rolling, or the stress in the connection Caused by concentration.

In order to solve such a problem, an invention relating to a reinforced soil structure already filed by the applicant of the present invention (Japanese Patent Publication Sho 59)
-20821) is known (see Figure 17).

However, these are all embankment reinforcements 23
The connecting portion 23a of the embankment 23 descends along the vertical rod 24 projecting from the wall panel 21, but when the embankment layer 20 is compressed and settles more than the descending length, the embankment reinforcement 23
There is a risk that a large shearing force will be generated in the connecting portion 23a of the above and the embankment reinforcement 23 will be sheared and broken at the connecting portion 23a.

That is, when a shear load is applied to the connecting portion 23a of the embankment reinforcement 23 installed in the embankment layer 20 along its cross section, the shear force is applied by the shear force before the tensile force of the embankment reinforcement 23 sufficiently acts. It is easily broken. Therefore, it is desirable that the wall structure of the reinforced soil structure is such that such a shearing force does not act on the embankment reinforcing material 23, and only a tensile force acts in the length direction of the embankment reinforcing material 23.

In addition, in this type of wall structure, the function required of the embankment reinforcement 23 is that the embankment layer has no tensile force.
It is to give the tensile strength of the embankment reinforcement 23 to 20, and originally, since the embankment reinforcement 23 can be integrated with the compressible embankment, it is desirable that it has flexibility, so the member cross section is A smaller value is more preferable, and a larger tensile strength is more preferable. In addition, it is of course desirable that the tensile resistance is large.

For these reasons, it is difficult to use a highly compressible cohesive soil such as Kanto loam, which is widely used as a locally generated material in Japan, as the embankment material.

According to the present invention, the connecting portion between the embankment reinforcing material and the wall panel is not only slid downward by the compressive settlement of the embankment layer but also slidable so that the locally generated material having high compressibility can be used as the embankment material. When the embankment reinforcement subsides to the limit, the compressive settlement of the embankment layer further causes the connecting part of the embankment reinforcement to rotate downward, so that shearing force is applied to the embankment reinforcement connection. It is a structure that is hard to act and can withstand only by the tensile force of the embankment reinforcement.

The present invention has been made in consideration of the above point, and the embankment reinforcing material sinks following the compressive settlement of the embankment layer, and when the settlement reaches the limit, the embankment reinforcing material. The object is to provide a wall structure of a bank embankment reinforced structure in which a shearing force does not act as much as possible on the connecting part by making the structure rotate downward at the connecting part with the wall panel so that only tensile force acts. To do.
