Description

Retaining wall block with improved bonding strength {RETAINING WALL BLOCK WITH IMPROVED COHESION}

The present invention relates to a retaining wall block having improved bonding force, and more particularly, to a retaining wall block having improved bonding strength by installing each coupling part on each retaining wall block to easily bind it, and securing an adhesive area for each bonding part.

In general, a retaining wall (擁壁, retaining wall) is a structure to prevent the soil from collapsing by masonry on the slope of the roadside, embankment, coast, or cut-off site formed by civil engineering works such as landscape wall surface, topographical factors and construction After that, it will be constructed considering the pressure distribution applied to the retaining wall.

In the conventional retaining wall, reinforcing bars forming the skeleton of the retaining wall are arranged in a certain shape on the embankment surface or the cut surface, the reinforcing bars are wrapped with a form, and then concrete is poured and cured between the formwork to form the wall, and then the wall is formed. It was built in such a way that the back side of the building was filled with reinforcing soil containing soil, crushed stone, and rubble.

Reinforced concrete retaining walls constructed using reinforcing bars and concrete as described above have a very complicated construction process and consume a lot of construction period, which requires enormous construction costs, and has disadvantages in that the appearance is extremely monotonous and dreary.

Accordingly, recently, in order to solve the problems of reinforced concrete retaining walls, a method of constructing retaining walls by building blocks is widely used. The construction is performed by filling the reinforcing soil, and reinforcing members such as mesh grids, geogrids and anchors are inserted between the retaining wall blocks to prevent collapse due to horizontal earth pressure to prevent the collapse of the retaining wall due to earth pressure.

In order to overcome this problem, Republic of Korea Utility Model Registration No. 340648 (hereinafter referred to as "prior art") has been disclosed.

The prior art is interposed between the concrete retaining wall block body 10 in which the soil filling hole 16 is formed at the front end and the rear end, and the retaining wall block body 10 stacked in a row to prevent separation of the retaining wall block body 10 At the same time, the retaining wall block body 10 has a structure in which a fixing pin 10 for supporting the upper retaining wall block body 10 is provided so that the retaining wall block body 10 is stacked at a predetermined angle.

However, in the case of the conventional retaining wall block configured as described above, there is an advantage in that the retaining wall block body to be built on the upper side using the fixing pin is prevented from being pushed forward due to the continuous earth pressure, but the rear side of the block is the side Since no components are provided to prevent lateral flow, the block cannot be masonry stably as the rear side of the block flows laterally when a lateral pressure is applied.

In addition, since the masonry is made only when the rear wall of the soil filling hole of the upper block is in close contact with the fixing pin of the lower block when the block is masonry, the inclination of the blocks is always the same regardless of the height of the retaining wall to be built. there is. That is, when the retaining wall is low, it is preferable to make the inclination of the retaining wall almost vertical to allow more soil to be incorporated into the retaining wall, but the inclination of the retaining wall cannot be adjusted according to the height of the retaining wall with conventional blocks.

In addition, the conventional retaining wall blocks have a problem in that the durability of the retaining wall blocks is deteriorated as the retaining wall blocks are installed misaligned or installed misaligned due to the gap between the retaining wall blocks or the poor coupling force when the retaining wall blocks are loaded.
