Retaining wall block construction method {METHOD FOR CONSTRUCTING RETAINING WALL BLOCK}

The present invention relates to a method for constructing a retaining wall block, and more particularly, to construct the first concrete layer and the second concrete layer for reinforcing wall to be inclined toward the front from an inclined ground to be inclined at the same time, and at the same time to engage the hollow portion and the engaging protrusion. It is possible to achieve mutually solid assembly, and furthermore, by laying crushed stone or soil in the hollow while stacking blocks to promote mutual support, and making the appearance more beautiful by the combination of vertical stacking and stacking. It relates to a retaining wall block construction method capable of improving the environment by vegetation of landscaping flowers in the hollow part exposed to the outside during stacking.

In general, the retaining wall is a structure for preventing soil from collapsing by resisting soil pressure, and is completed by stacking blocks for suppressing soil on one side of an inclined ground to maintain the difference in elevation.

Gravity retaining walls, for example, are in the form of retaining walls without reinforcement soils that withstand the load of soil confined by the weight of the block itself.

In the case of such a gravity retaining wall, each block is composed of concrete or stone lumps, so there is a disadvantage in that a lot of construction costs are required.

The cantilevered retaining wall typically has a structure of slab piles poured into the soil and is a form of retaining wall that obtains support from the resistance to the rotation of the slab pile under the supported soil.

On the other hand, the retaining wall must be able to withstand the upper structure and earth pressure sufficiently, be durable, easy to secure materials, and easy to install. In general, shafts have these requirements. There is a disadvantage that the resistance to water pressure falls.

Furthermore, the concrete retaining wall is one of the most commonly used structures at present, but there is a shortage of professional manpower in the construction market, resulting in higher labor costs, difficulty in quality control for cast-in-place concrete, and structural wall weakness when the retaining wall height increases. There are many problems such as an increase in construction cost.

In order to improve these problems, a variety of new retaining wall construction methods have been developed and put into practice in recent years, and the most typical construction method is a retaining wall block construction method using blocks.

An object of the present invention is to construct the first concrete layer and the second concrete layer for reinforcing wall to be inclined finely toward the front from the inclined ground so that the rainwater is permeated through the reinforced soil or the inclined ground, the first concrete layer and the first concrete layer It is to provide a retaining wall block construction method that can be flowed forward by the concrete layer 2 to flow underground through the rubble for drainage of groups 1 to 3.

An object of the present invention is to pile up blocks to install crushed stone or soil in the hollow portion to enhance mutual support, and to make the appearance more beautiful as a combination of vertical stacking and stacking, while being exposed to the outside during stacking The present invention provides a method of constructing a retaining wall block in which a landscape plant is planted in a hollow part to enable environmental improvement.

The first concrete layer and the second concrete layer buried in the rubble for drainage of the first to third groups are characterized in that the drain hole is formed in the vertical direction through the technical method.

According to the present invention, when the first concrete layer and the second concrete layer for reinforcing wall reinforcement are inclined toward the front from the inclined ground, the first concrete layer and the second concrete when the rainwater penetrates through the reinforced soil or the inclined ground It is possible to naturally flow forward by the layer so that it can flow underground through the 1st to 3rd group of rubble for drainage, thereby preventing the ground from weakening or the collapse of the ground. .

The present invention is formed by penetrating the drain hole in the vertical direction in the first concrete layer and the second concrete layer buried in the rubble for drainage of groups 1 to 3 so that the rain flows downward through the drain hole naturally. It works.

The present invention can alternately horizontally spread a synthetic mesh (MESH; geogrid) between the blocks of groups 1 to 3, and the rubble and reinforcement soils of groups 1 to 3 to increase mutual traction and support. In addition, there is an advantage that allows the landscaping by planting the flowers in the hollow exposed to the outside by selectively stacking the blocks of the group 2 and 3 in accordance with the slope of the inclined ground.

The present invention has the effect of laying the soil in the hollow portion of the block made of piles to enable the vegetation of flowers, and by installing crushed stone in the hollow portion of the block other than the soil block is installed to promote a firm interlocking have.
