Description

BELT TYPE GLASS FIBER REINFORCEMENTS AND RETAINING WALLS USING THE SAME}

The present invention relates to a strip-shaped glass fiber reinforcement material and a retaining wall structure using the same, and more specifically, to support the wall of the reinforced earth retaining wall by using a strip-shaped glass fiber reinforcement for pulling and supporting one side of the retaining wall or wall, It is related with a retaining wall structure in which the retaining wall is prevented from collapsing.

In general, in the case of supporting a block forming a retaining wall wall using a band-shaped fiber reinforcement, a support wall spaced apart from the rear side of the block by hanging a band-shaped fiber reinforcement on a connecting ring which protrudes from the back of the block. The other end of the band-shaped fiber reinforcement is hung in one end to the connecting ring fixed to the support rod fixed in front of the zigzag continuous installation, and then fill the reinforcement soil between the block and the support wall to form the retaining wall structure.

However, these strip-shaped fiber reinforcement and retaining wall structure has the following problems.

Since the band-shaped fiber reinforcement is supported by the connecting ring protruding from the back surface of each block, a difference occurs in the supporting force for supporting the block by the pulling force when the band-shaped fiber reinforcement is continuously laid in a zigzag. Therefore, there is a problem that the front surface of the retaining wall wall is not evenly formed in the plane.

Then, as time passes, the strip-shaped fiber reinforcement increases due to the continuous load of the block and the reinforcement soil, and thus the retaining wall is broken because the retaining force of the retaining wall is not maintained.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a strip-shaped glass fiber reinforcement and a retaining wall structure using the same supporting force for supporting the block forming the wall of the retaining wall.

Another object of the present invention is to provide a strip-shaped glass fiber reinforcement having excellent strength and durability and a retaining wall structure using the same.

The strip-shaped glass fiber reinforcement according to the present invention for achieving the above object, the glass fiber sheet is densely woven and coated with a glass fiber so as to have a predetermined width, and a cover of nylon material surrounding the glass fiber sheet It is characterized by having a configuration to include.

The glass fiber sheet is formed to have a width of more than 5cm and a tensile strength of 0.5TON or more by forming a glass fiber of more than 1200 tex 14 or more, characterized in that the coating by resin.

The retaining wall structure according to the present invention includes a support wall formed by cutting or filling and having an inclination or verticality, a vegetation block layer formed to be spaced from the support wall, and greening, and across the entire surface of the support wall. A rod-shaped first horizontal supporter to be installed, a rod-shaped second horizontal supporter to be installed across the rear surface of the vegetation block layer, and between the first horizontal supporter and the second horizontal supporter. It includes a strip-shaped glass fiber reinforcement for supporting one side of the vegetation block layer by zigzag connection, characterized in that the support wall and the vegetation block layer is filled with reinforcement soil.

The strip-shaped glass fiber reinforcement is characterized in that it comprises a glass fiber sheet woven tightly to have a predetermined width and the coating is made of a glass fiber sheet and a cover made of nylon covering the glass fiber sheet.

Each of the first horizontal support and the second horizontal support is disposed up and down, and the strip-shaped glass fiber reinforcement includes a first horizontal support and at least one second horizontal support adjacent to the first horizontal support. It is characterized by connecting.

The strip-shaped glass fiber reinforcement and the retaining wall structure using the same according to the present invention have the following effects.

In the retaining wall structure according to the present invention, a rod-shaped first transverse support provided across the front surface of the support wall and a rod-shaped second transverse support provided across the rear surface of the vegetation block layer are provided. And a band-shaped glass fiber reinforcement for supporting one side of the vegetation block layer by zigzag connection between the first horizontal support and the second horizontal support.

The first horizontal support is installed across the front of the support wall, the second horizontal support is installed across one of the rear of the plurality of vegetation blocks.

Therefore, when continuously installing a strip-shaped glass fiber reinforcement in a zigzag between the first cross support and the second cross support, the pulling force is not even applied directly to the block and is evenly distributed by the first cross support and the second cross support. Therefore, the supporting force for supporting the vegetation block forming the wall of the retaining wall has a uniform effect.

In addition, the strip-shaped glass fiber reinforcing material according to the present invention comprises a glass fiber sheet in which the glass fiber is densely woven and coated to have a predetermined width, and a cover made of nylon covering the glass fiber. The glass fiber has less than 5% elongation and is less stretched than other materials such as polyester having 15% or more elongation.

Therefore, the strength and durability is excellent, there is an effect that can continuously support the retaining wall walls without increasing the continuous load of vegetation block and reinforcement soil.
