Description

Segmental Block-faced Retaining Wall System

The present invention relates to a reinforcement earth retaining wall, and more particularly to an assembly for reinforcement earth retaining wall for preventing slope slope collapse due to earth pressure.

Generally, reinforcement soil retaining wall is a wall that prevents soil from collapsing due to soil pressure, and it is the ground that occurs when the slope of the ground becomes steeper than that. It is a structure in which a plurality of reinforcement retaining wall assemblies are combined to prevent collapse.

1 is a view showing the assembly for a general reinforced earth retaining wall.

As shown in FIG. 1, a general reinforcement soil retaining wall assembly includes a plurality of elliptical through holes 10-1 and first and second circular coupling grooves 10-3 and 10-4 on the upper side thereof. And a "yo" -shaped retaining wall block (10) for supporting a slope or a normal surface of an incision formed by a civil works such as a dike, a riverbank, a landscaping wall, and preventing soil from being collapsed, and the "yo" -shaped retaining wall block (10). It is inserted into and fixed in the first coupling groove (10-3) or the second coupling groove (10-4) of the geogrid 30 of the geogrid 30 to be described later is passed through one side of the geogrid (30) Rod-shaped connecting pin 20 to increase frictional force, pull resistance, and shear stress with soil, and connects a plurality of horizontal bars 30-3 and vertical bars 30-5 to form an elliptical fastening hole 30-1. Geogrid for forming a friction force with the soil, pull-out resistance, shear stress by forming a close contact with the connecting pin 20 to the fastening hole (30-1) ( Geogrid).

2 and 3 are views showing a state in which the retaining wall is installed using the reinforcement soil retaining wall assembly of FIG.

As shown in Figs. 2 and 3, the first layer is stacked by placing the "yo" retaining wall block 10 on the bottom of the foundation having good drainage.

Then, the rod-shaped connecting pin 20 is fixedly inserted into the first circular coupling groove 10-3 or the second circular coupling groove 10-4 formed in the “yo” -shaped retaining wall block 10.

Thereafter, the connecting pin 20 is inserted into close contact with the fastening hole (30-1) of the geogrid (30).

On the other hand, the "yo" shaped retaining wall block 10 of the second layer is stacked on the upper surface of the "yo" shaped retaining wall block 10 of the first layer.

N layer "Y" shaped retaining wall blocks have two inclination angles, which are sequentially placed on the upper surface of the "yo" retaining wall block of the first layer. There was a problem in that it is not possible to install retaining walls having various slopes.

Therefore, when the retaining wall is stacked with the conventional reinforcement earth retaining wall assembly, the retaining wall inclination angle is limited to only two according to the conditions of the area to be stacked (according to the wide and narrow area of the site). There was a problem that flexibility is extremely limited.

In addition, as shown in Figure 4, in order to increase the frictional force, pullout resistance, and shear stress with the backfilling soil (reinforced soil) of the retaining wall, the connecting pin is inserted into the fastening hole of the geogrid, but the connecting pin is connected to one side bar of the fastening hole There was a problem that the friction, pullout resistance, and shear stress with the backfill soil of the retaining wall did not increase significantly because they did not adhere to the vertical bars.

For this reason, there is a problem that the retaining wall is often collapsed by the reinforcement soil.

In particular, the handle is not installed on the "yo" retaining wall block, so that when the user carries the "yo" retaining wall block, there is a problem that a very large amount of power is consumed.

Therefore, the present invention has been proposed to solve the above problems according to the prior art, an object of the present invention to provide a reinforcement soil retaining wall assembly for preventing slope slope due to earth pressure.
