Geocell Installation In Foundation Reinforcement

Geocell Installation In Foundation Reinforcement

1.Base Preparation

Where specified, install a suitable geotextile as a separator. A woven or nonwoven fabric is selected depending on whether strength or permeability is important. Simply unroll the geotextile directly on the subgrade, overlapping adjacent panels by 45cm (minimum).

2.Deployment of  Geocell

Position the collapsed section on the place where is determined to be first installation.

Install a series of temporary stakes or pins over which selected edge cells would be hooked. Noose the edge of the section, stretch it to maximum area and allow it relaxed. Accurate positioning for the edge cells will be able to minimize the number of working crew required for the deployment. Additional stakes may be needed along perimeter in order to get full expansion of each cell.

An installation frame may be needed where it is not practical to use stakes (over rocky soil, etc.)

3.Infill material

The fill material should be selected to meet the project and earth properties. Fill the cells with a front-end loader or dump truck (caution: Excessive drop-height might hurt the cells. Drop-height<1m is suggested) and push the fill into cells using shovels or a bull-dozer blade. Continue until all cells are filled. Never allow any equipment to drive over unfilled area. And always overfill the cells slightly to allow for consolidation.

4.Compact

It is necessary to compact the Geocell system. The most common method of compacting is through repeated passes by the road roller used the spread the infill. A versatile equipment and/or water may be required to achieve the specified compaction.

5.Assembling accessories

Screw sets

J-Pins or fiberglass anchor

Adjacent sections are installed in a similar fashion and butted with rivets, riveting every cell to cell to achieve continuous coverage.
