DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a retaining wall block which is laid up, down, left and right over a slope to prevent collapse of a slope such as a road, a river, a shore, along a railroad track. Further, the present invention relates to a retaining wall block having an insert coupling structure, and further relates to a retaining wall construction method using the retaining wall block having the insert coupling structure.

[0002]

2. Description of the Related Art It is known to install a retaining wall block on a slope such as a road, a river, a shore, along a railroad track, or the like in order to prevent the slope from collapsing.
Conventionally known retaining wall blocks have been devised in various ways in order to improve the workability.

For example, in a conventionally known installation operation, individual retaining wall blocks are suspended by a crane, transported to a predetermined position, and sequentially stacked. In order to speed up the installation work, it is important that each retaining wall block is lightweight and has a self-standing structure. To reduce the weight of the retaining wall, it is preferable to use a wall block made of a plate.

[Problems to be solved by the invention]

[0004] However, in the case of a retaining wall using a conventionally known wall block made of a plate, the individual wall blocks cannot stand on their own, which takes time for installation work, and inevitably increases the cost and the construction period. Was.

[0005] Also, vegetation could not be formed with the above-mentioned conventionally known retaining wall. Furthermore, it was difficult to determine the angle of inclination of the wall block. In addition, to hold the wall block,
It is necessary to provide a support from the front and the back, which increases the work cost.

Accordingly, an object of the present invention is to improve the disadvantages of the conventionally known wall block made of a plate body, to simplify the construction work, to shorten the construction period, and to reduce the cost. It is an object of the present invention to provide a retaining wall block having a coupling structure and a method of constructing a retaining wall using the insert coupling retaining wall block. Another object of the present invention is to provide a method for constructing a retaining wall using an insert-coupled retaining wall block that enables vegetation.

[0007]

The feature of the present invention lies in the following constitution. That is, in a retaining wall block installed on an inclined surface such as a road, a river, a shore, or along a railroad track, the retaining wall block includes a base block and a wall block that is insert-coupled to the basic block. A retaining wall block having an insert connection structure, comprising a head having a groove and an anchor portion embedded in the ground, wherein the wall block is inserted into an insert groove of a head of the base block.

[0008] Another feature of the present invention is that:
One or more basic blocks are provided for one wall block, and more preferably two basic blocks are provided for one wall block.

Another feature of the present invention resides in that an anchor is provided on the wall block.

Another feature of the present invention is a method of constructing a retaining wall block installed on an inclined surface such as a road, a river, a shore, or along a railroad track. , The wall block is inserted into an insert groove provided in the head of the base block to assemble and stand alone, and then a backfill material is injected into the back surface of the wall block and compacted. The construction method of the retaining wall using the joint retaining wall block.

Another feature of the present invention is that a plurality of basic blocks are arranged again on the backing material, and the wall block is inserted again into an insert groove provided in a head of the basic block. The self-assembly is performed, and then a backfill material is put into the back of the wall block again and compacted, and two or more steps are combined.

Another feature of the present invention is that
One wall block is provided for two or more basic blocks, and one wall block is provided for two basic blocks.

Another feature of the present invention resides in that an anchor is provided on the wall block, and that the plant is vegetated on the front part not covered by the base block and the wall block.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing an insert coupling structure of a retaining wall block according to one embodiment of the present invention, FIG. 2 is a front view of the retaining wall, and FIG. 3 is a plan view of the retaining wall of FIG.

The retaining wall block 1 of this embodiment is installed on a sloped surface S such as a road, a river, a shore, along a railroad track, etc., in which the front surface is leveled. The retaining wall block 1 comprises a base block 2 and a wall block 3 which is insert-coupled to the base block 2. The base block 2 includes a head 2A having an insert groove 4 and an anchor 2B buried in the ground. The anchor portion 2B also has the function of receiving earth pressure from above. The insert groove 4 formed in the head 2A is perpendicular or slightly inclined with respect to the vertical direction. The wall block 3 is inserted into the insert groove 4 of the head 2A of the base block 2.

One or more basic blocks 2 are provided for one wall block 3. In this embodiment, two basic blocks 2 are provided for one wall block 3. . Anchor 5 is provided on wall block 3,
An end of the anchor 5 is embedded in the inclined surface S.

The front part which is not covered by the base block 2 and the wall block 3 is a green part, and suitable plants are vegetated.

The construction method will be described with reference to FIG. A plurality of first-stage basic blocks 2 are arranged by leveling the front surface of a slope S such as a road, a river, a shore, or along a track. And
The wall block 3 is inserted into an insert groove 4 provided in the base block 2, and is assembled and self-standing. Next, the backfill material 6 is put into the back surface of the wall block 3, and the anchor 5 is attached and compacted as needed.

Next, the second-stage basic block 2 is placed on the backfill material 6. Then, the second-stage wall block 3 is inserted into the insert groove 4 provided in the base block 2, and the assembly is made independent. Next, a second-stage backfill material 6 is put on the back surface of the wall block 3, and an anchor 5 is attached and compacted as necessary. These steps are combined in a required number of steps to construct a retaining wall having an insert coupling structure.

It is to be noted that an appropriate number of steps can be selected as long as the number of steps of the retaining wall is one or more. Further, the anchor 5 of the wall block 3 can be omitted as necessary.

Next, if necessary, the front part not covered by the base block 2 and the wall block 3 is used as a greening part, and appropriate plants are vegetated.

[0022]

According to the present invention described above, the following effects can be obtained. According to the present invention, since the individual wall blocks can stand alone, the installation work is simplified, and the cost and the construction period are reduced. In addition, since the front can be easily vegetated, a greening retaining wall can be obtained. Furthermore,
Since the wall block is inserted into the insert groove, it is easy to set the inclination angle of the wall block constant. Further, it is not necessary to provide a support from the front surface or the rear surface in order to insert-hold the wall block in the insert groove, so that the operation cost is reduced.
