  • Geocell Retaining Wall Method

Features

1. High weather resistance and chemical resistance

The raw material for geocell is high-density polyethylene, and the surface sheet is a 1.5 mm thick sheet with texture processing (0.2 mm), so it has sufficient weather resistance. It also has excellent chemical resistance and is suitable for all soils, including acidic and alkaline soils.

2. Lightweight and compact

The Terrace Cell used in the geocell retaining wall method is lightweight at about 4 kg per sheet, so it can be easily transported. In addition, it is stored in a compact state, so it does not require a large space to store the material.

3. Easy and quick construction

It uses few materials, and the construction method involves repeated work of unfolding, filling, and compacting, so the construction period can be shortened. Therefore, it is effective in small sites and disaster recovery. In addition, since it does not use concrete, there is no need for a curing period, and the construction period can be shortened.

4. Various filling materials can be used

Since geocell has a honeycomb structure, various filling materials such as local soil and crushed stone can be used according to the situation by constraining the filling material.

5. High adaptability and flexibility according to the site

The wall slope is 1:0.1 to 1.0, and can be used for wall heights up to 8m, making it easy to work on curved sections and change the slope according to local conditions. In addition, because it is a flexible material, foundation concrete is not required and it can follow a certain degree of uneven ground settlement.

6. Greening is possible

By using a filling material that can be planted, it is possible to plant plants in the setback areas and green the area by attracting native species.

Installation example

Construction procedure

1. Geocell deployment

The terracell is deployed to the specified size on the auxiliary frame.

2. Leveling the foundation ground and installing the geocell

The deployed geocell is installed at the specified gradient. For corner construction and folding construction, an auxiliary frame for corners is used.

3. Geocell connection

The geocells are joined together with connection screws and cell locks.

4. Spreading and compacting the soil

The filler material is spread and compacted.

5. Installation of suction prevention material

An anti-suction cloth is installed as a separator between the crushed stone layer and the generated soil, or as a drainage material.

6. Casting auxiliary rebars

In order to increase the integration of the top and bottom, cast rebars D19 (L=1.0m) at 2 bars/m every 6 levels (90cm).

7. Installing crack suppression material

Install long fiber nonwoven Trepp TT-3S.

8. Installing geocell bags (sandbags)

Secure the geocell bags with resin anchor pins to protect the top edge, and the work is complete.
