Retaining wall using reinforcement soil blocks and constuction method of retaining wall using that at cutting ground}

The present invention relates to a retaining wall, and more particularly, to a retaining wall construction method using the same in a retaining wall and a cut ground using a reinforcing soil block for constructing a retaining wall while stacking a reinforcing soil block into a fitting groove of a support without using a reinforcing material.

In general, the slopes of roadsides where landscaping work is not properly done during the civil engineering work often caused inadvertent accidents to vehicles or people due to the collapse of soil on the roadsides due to flooding or wind damage.

Therefore, retaining walls have been installed in places where soil or stones fall from the soil having slopes on the soil silos or roadsides to the roadside.

In general, a retaining wall was constructed by placing a reinforcing bar in a mold having a retaining wall model, and then pouring concrete in which cement, sand, gravel, and water were properly mixed in a constant ratio.

However, there is a problem that the retaining wall has to be constructed through a cumbersome work process such as removing the mold structure after a certain time has elapsed by making a mold structure and putting concrete and steel into the mold structure.

In addition, the concrete retaining wall method used in the fill soil requires the excavation space on the back, and the work time is long due to curing time and work method, and the existing concrete retaining wall method used for the cut ground has many work processes. There is a problem in that the cost is increased because the time is lengthened and slope reinforcement work in parallel.

Therefore, in Korea, reinforcement soil retaining wall method is generally used instead of reinforced concrete retaining wall or stonework that was used in the past to reinforce building site construction or slope topography due to the topography.

However, reinforcement installation and drainage are essential methods in constructing retaining walls. There are various types of reinforcement used.

On the other hand, the reinforcement retaining wall method used in the fill soil requires the backfill space for installing the reinforcement, and there is a disadvantage that the pile cannot be installed in the backfill space. After cutting and slope reinforcement work, the reinforcement soil block and connecting reinforcement was installed from the bottom to the top again, there was a problem in that the cost increased and the safety fell.

In addition, the conventional reinforcement earth block is not only monotonous with the simple design and color appearing in appearance, but also could not enhance the aesthetics of the street, and even when using the vegetation block, waste materials for demolition using materials that are not environmentally friendly such as concrete There was a problem in mass production.

An object of the present invention is to solve the above problems when forming a retaining wall structure on the ground, cut ground, soft ground reinforcement earth block to build the retaining wall using only the reinforcement earth block of the support and lightweight concrete material without reinforcement In order to provide a retaining wall construction method using the same in retaining wall and cut ground.
