Description

Retaining wall block

The present invention relates to a retaining wall block, and more particularly, to a retaining wall block used for constructing a retaining wall for supporting gravel.

In general, a retaining wall is a wall made of a material that prevents the soil from collapsing against the earth pressure, and is a structure made to prevent the ground collapse that occurs when the steep slope of the ground is set to a steep slope.

One of the methods for stacking such a retaining wall is to stack a plurality of blocks in a layer, and the block used at this time is called a retaining wall block.

If the retaining wall block thus constructed does not have a sufficient supporting force with respect to the toe pressure, there may occur a 'back-burning phenomenon' of the retaining wall which is pushed forward by the back earth pressure.

Accordingly, the conventional retaining wall block includes a separate support structure for having the shear resistance against the soil pressure. Generally, the supporting structure of the retaining wall block is largely a geogrid anchor structure and a resistor anchor structure.

First, the geogrid anchor structure refers to a structure in which reinforcement fibers or steel wires are formed in the form of a mesh and the tip ends thereof are connected to the rear of the retaining wall block. Also, the resistor anchor structure has a structure in which a tensile rod such as a reinforcing bar, a steel bar, or an FRP rod is bent, and the bent portion generated in this way is fixed to an insertion groove formed perpendicularly to a front wall surface or a rear wall surface of the retaining wall block.

However, the conventional support structure is disadvantageous in terms of economical efficiency due to many parts constituting the geogrid and the anchor means, and it takes a long time to construct because the geogrid and the anchor means must be assembled in the retaining wall block in the field.

In order to solve the above problem, a retaining wall block capable of supporting the retaining wall by the block alone has been proposed. Korean Patent Laid-Open No. 10-2011-0037317 discloses a technology related to this. Here, a body formed by extending the left and right portions of the binding portion extending from the front end to the left and the right extends over the respective supporting portions of two retaining wall blocks formed adjacent to each other and extending rearward from the back face of the binding portion, And a support block that is embedded in the block body and supports the block body.

However, in the conventional retaining wall block, the supporting block is a large block, and its weight is considerable, so that it is not only difficult to transport but also has a problem that the efficiency of construction is reduced due to the weight of the retaining block.

It is an object of the present invention to provide a retaining wall block which is excellent in resistance to earth pressure and is light in weight and easy to construct.

According to another aspect of the present invention, there is provided a retaining wall block comprising a plurality of block members stacked one on the other by a connecting pin, An extension portion disposed at the rear of the block portion, the extension portion having a receiving space for accommodating the reinforcing soil therein; And a wedge portion having one side engaged with the block portion and the other side coupled with the extended portion.

Wherein the extension comprises: front and rear panels spaced apart in a back and forth direction; And side panels spaced parallel to each other and connecting the front and rear panels.

In addition, it is preferable that a plurality of recesses are formed on the front side of the upper surface of the block portion, in which one side of the connection pin is inserted. Here, the block portion may be formed at a front side of the lower surface with a receiving groove into which the other side of the connecting pin is inserted.

The block portion may have a first wedge groove formed at a rear end of the block portion so that one side of the wedge portion is inserted and widened forward.

Preferably, the front panel is formed with a second wedge groove in which the other side of the wedge is inserted and widened toward the rear.

According to the retaining wall block according to the present invention, the following effects can be obtained.

First, by extending the longitudinal length of the retaining wall block by disposing the extended portion behind the block portion, the resistance against the earth pressure can be increased by itself.

Secondly, the extension part is provided in a box shape opened to the upper and lower sides to minimize the weight, thereby facilitating the transportation and construction of the retaining wall block.

Third, the front angle can be adjusted, so various types of construction can be done.

Fourth, the wedge portion is fitted to the block portion and the extended portion to maintain a firmly coupled state, and the manufacturing cost can be simplified, thereby reducing manufacturing cost and manufacturing time.
