Description

MULTI RETAINING WALL BLOCK APPLICABLE VARIOUS STIFFENER AND RETAINING WALL CONSTRUCTING METHOD USING THIS}

The present invention relates to a retaining wall block, and more particularly, even if a crack is generated in the rear block or the front block due to the unbalanced load after the construction of the retaining wall, the crack does not proceed to the other block and the crack is generated. It is easy to replace only the old blocks, so that the retaining wall repair work can be performed at the minimum maintenance cost, and the weight of the retaining wall block itself can be distributed to the rear block and the front block to greatly improve handling and construction. In addition, the present invention relates to a multi retaining wall block capable of applying various reinforcing materials that can share different types of reinforcing materials (anchor blocks, mesh grids, foot grids, etc.) and a retaining wall construction method using the same.

In general, the retaining wall refers to a wall made so that the soil of the land or incision surface does not collapse or flow due to soil pressure. In this case, the structure is constructed to prevent ground collapse.

Such conventional retaining wall is formed by weaving and installing reinforcing bars in horizontal and longitudinal directions on the ground or incision surface, wrapping them with formwork, and then forming concrete in the formwork to form walls. The walls were constructed in such a way that the reinforcement soils including soil, crushed stone and rubble were filled on the back surface of the wall.

However, such a reinforced concrete retaining wall has a disadvantage in that the construction process is very complicated and a lot of construction period is consumed, thus enormous construction cost.

In order to solve such a conventional problem, a retaining wall construction technique has recently been proposed in which a plurality of retaining wall blocks are stacked in a longitudinal direction and a transverse direction along a fill surface or an incision surface, and then built in such a manner as to fill rubble on the back surface thereof. .

However, there is a problem in that the retaining wall constructed using the conventional retaining wall block is not beautiful because the whole is made of concrete.

Accordingly, the present inventors recently proposed a retaining wall block to which a front natural stone is attached as a patent application No. 2008-0131833.

The prior art of the patent application No. 2008-0131833 is coupled to the front of the retaining wall block body by combining a separate engaging piece, and attaching a natural stone plate on the front of the technology, which is an advanced step than the existing retaining wall block, Since it is made of a single body, the weight is heavy, there is a problem that handling is inconvenient and poor workability.

In general, in the land, incisions, etc., a retaining wall that supports earth pressure on one side or prevents the collapse of the slope is constructed to withstand the earth pressure acting on the retaining wall.

Such a retaining wall refers to a wall that prevents soil from collapsing by resisting soil pressure, and is a structure made to prevent ground collapse when a stable slope of the ground surface is steeper than that.

The conventional retaining wall is formed by arranging reinforcing bars forming the skeleton of the retaining wall in the form of a retaining wall or incision surface, wrapping the reinforcing bars with formwork, and then curing by pouring concrete in the formwork to form walls. It was constructed by filling reinforcement soils including soil, crushed stone, rubble, etc.

However, such a reinforced concrete retaining wall has a disadvantage in that the construction process is very complicated and the construction period is consumed a great deal of cost.

In order to solve the problems of the conventional retaining wall, a retaining wall construction using a retaining wall block has recently been disclosed. Retaining wall construction method using such a retaining wall block is constructed by stacking a plurality of retaining wall blocks in the transverse direction along the fill surface or incision surface and then fill the rubble with the back surface.

However, the retaining wall constructed by using such a conventional retaining wall block has a problem in that the whole is made of concrete to promote the upper urban aesthetics.

Thus, a technique of attaching natural stone material using a stone bond or mortar on the front surface of the retaining wall block has been disclosed to improve the aesthetics of the retaining wall block.

However, such a conventional retaining wall block has the following problems.

Retaining wall using retaining wall block sporadically cracks the retaining wall block after a certain period of time after construction, and natural stone slabs are easily removed, resulting in damage to the city's aesthetics and creating a sense of pressure on the retaining wall collapse for nearby residents. .

In addition, in order to repair the retaining wall block in which the crack has occurred, there is a problem in that a high maintenance cost is required because the entire retaining wall block in which the crack has occurred is replaced.

On the other hand, the retaining wall is embedded in the retaining wall block, the filling material filled in the rear of the retaining wall block (between the retaining wall block and the slope) and the filling material in multiple stages, and the front end is connected to the retaining wall block, and the retaining wall block is connected to the retaining wall block. It is composed of supporting reinforcement, and the reinforcement is a variety of products such as anchor block, concrete grid having a plurality of holes, foot grid is used, and the retaining wall block is configured to use only one of the reinforcement of the conventional reinforcement Accordingly, there is a problem in that various retaining wall blocks cannot be used and restrictions on using the retaining wall blocks and reinforcement materials are provided.

The present invention is to solve the problems described above, even if the crack occurs in the rear block or the front block due to the unbalanced load after the construction of the retaining wall so that the crack does not proceed to the other block and at the same time By simply replacing the generated blocks, the retaining wall repair work can be carried out with minimal maintenance cost, and the weight of the retaining wall block itself is distributed to the rear block and the front block to greatly improve handling and construction. The purpose of the present invention is to provide a multi retaining wall block and a retaining wall construction method that can be applied to various reinforcement materials that can share different types of reinforcement materials (anchor blocks, mesh grids, foot grids, etc.).

According to the multi retaining wall block and the retaining wall construction method using the same according to the present invention, when a crack is generated in the rear block or the front block due to the unbalanced load after the construction of the retaining wall, the rear block and the front block and Since the decorative plate is composed separately, the crack generated in one block does not proceed to the other block, and only the corresponding block in which the crack is generated can be easily replaced, thus maintaining the retaining wall with minimum maintenance cost. It is possible to install different types of reinforcement materials (anchor blocks, mesh grids, foot grids, etc.) selectively to the first to third reinforcement joints, so that various reinforcements can be shared and the retaining wall block and reinforcement can be selected when constructing the retaining wall. Has the effect of widening.

And, when the reinforcement is fixed together to the front block and the rear block through the first reinforcement connecting portion, the separation of the front block and the rear block by the external force (earth pressure, etc.) by increasing the binding force of the front block and the rear block together with the connection of the reinforcement. There is an effect that can be prevented.
