Description

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

The present invention relates to a retaining wall block with improved bonding strength, and more particularly, to a retaining wall block that can be easily bonded by installing each coupling portion on each retaining wall block, and improves the bonding strength by securing the adhesive area of each adhesive portion.

In general, retaining walls are structures to prevent sediment from collapsing due to masonry such as slopes of roads, levees, coastal areas, and landscaping areas formed by civil engineering works. The construction is carried out in consideration of the distribution of pressure applied to the retaining wall afterwards.

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

As such, the reinforced concrete retaining wall constructed using reinforced concrete and reinforced concrete has a disadvantage in that the construction process is very complicated and the construction period is consumed a lot, which incurs enormous construction costs, as well as an extremely monotonous and desolate appearance.

Accordingly, recently, in order to solve the problems of reinforced concrete retaining walls, a method of constructing a retaining wall by constructing a block has been widely used.This block construction method involves stacking a plurality of retaining wall blocks in several stages in the transverse direction, and then on the rear surface thereof. The construction is performed by filling the reinforcement 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 collapse of the retaining wall due to earth pressure.

In order to overcome this problem, Korean Utility Model Registration No. 340648 (hereinafter referred to as "conventional technology") has been disclosed.

The prior art is interposed between the concrete retaining wall block body 10 with the soil filling hole 16 formed at the front and rear ends and the retaining wall block body 10 stacked in a row to prevent the retaining wall block body 10 from being separated. At the same time, the retaining wall block body 10 has a structure in which a fixing pin 10 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, although it has the advantage of preventing the retaining wall block body mounted on the upper part from being pushed forward due to continuous earth pressure using a fixing pin, the rear side of the block is side Since components that prevent the flow in the direction are not provided, when pressure in the lateral direction is applied, the block cannot be stably built as the rear side of the block flows in the lateral direction.

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

In addition, the conventional retaining wall block has a problem that the durability of the retaining wall block is deteriorated because the retaining wall block is installed misaligned or displaced because the retaining wall block is displaced between the retaining wall blocks or when the retaining wall block is loaded.
