Accordingly, the present invention can reduce the construction site by assembling the block block combining the front cinder, hornblende, and the like on the front and the block block formed only for filling the soil in a modular or unit combining manner, It is possible to reduce the cost, and in particular, it is easy to carry, easy to assemble, and easy to assemble, so that excellent economic efficiency is secured and productivity is greatly improved.

Generally, the blocks used for the retaining walls of rivers are used to build walls that resist soil pressure and prevent the soil from falling down.

Such conventional retaining wall blocks for a river bed are mainly composed of concrete blocks, which are sequentially stacked on slopes and soft grounds of a river side to form a wall, and the river side is structurally reinforced.

Such a conventional concrete retaining wall block structurally reinforces the river side, but has a problem that it is not environmentally friendly.

That is, the conventional concrete retaining wall block covers the river side with the concrete retaining wall, seriously damaging the natural ecosystem of the river.

In addition, the conventional retaining wall block has a problem of securing the quantity of the river at the time of construction, and a problem of generating the oyster of the retaining wall structure due to the acceleration of the water flow, .

In order to solve such a problem, recently, as disclosed in the prior art of the patent application No. 10-2012-0061255, a gabion (gobion) is constructed on the slope of the river, and in such a case, And pumper stone, etc., are used as a retaining wall by laminating rectangular shapes.

Such conventional Gobion retaining wall is widely applied to landscaping retaining walls and landscapes in view of landscapes and nature-friendly aspects. It is easy to acquire in the field, and labor costs are low. .

However, such Gobion retaining wall has a problem in that the natural disruption of the riverside is intensified due to an increase in the number of stubborn stools in the field and the like.

In addition, in the conventional garbage construction method, a filling material such as rubble is put into a hexagonal wire mesh structure, and due to the nature of the construction method, a wire mesh filled with filler experiences a folding phenomenon which is bent outwardly of the wire mesh due to the weight of the filler.

In other words, by stacking the ferroconcrete and the hornblende in the form of a retaining wall in the iron netting, the two stages and the third stage are laminated in the form of a pyramid on the first stage. Since the wire net is broken due to the upper load, And the phenomenon of collapse without forming the shape is occurring.
