Textured geocell
A geocell for retaining infill in geotechnical structure, e.g. a protection construction on an unstable slope in mountainous areas, construction foundation, and green-making with plants, consists of several plastic plates; every two adjacent plastic plates are connected together at several spaced apart elongated joints by means of ultrasonic welding, each of which elongate joints includes several aligned points; thus, the geocell can be expanded into a honeycomb shape, and cells are formed therein for containing backfill therein; the plastic plates are formed with rough finishes so as to increase the backfill retaining capability of the present geocell.
1. Field of the Invention
The present invention relates to a geocell three-dimensional confinement system for retaining infill as a protective construction for slope protection, erosion control, ground stabilization, and retaining wall. More particularly, an infill is contained in geocells in the shape of honeycombs, which are composed of several plastic plates formed with rough surfaces for increasing the infill retaining capability of the geocell.
2. Brief Description of the Prior Art
A common geocell structure for retaining infill in geotechnical structure includes several plastic plates. Every two adjacent ones of the plastic plates are connected by ultrasonic welding or other methods together at several joints with certain ranges such that when the geocell is expanded, it will be in the shape of a honeycomb, which includes many cells for containing the infill, e.g. sand, stones, and earth, therein.

It is a main object of the present invention to provide a textured geocell to overcome the above disadvantages. Improved geotechnical structure can be a protection construction for slope protection, erosion control, ground stabilization, and retaining wall with plants.
The infill retained geocell of the present invention consists of several plastic plates, which have rough surfaces. Every two adjacent plastic plates are connected together at several joints by means of ultrasonic welding or other methods. Each of which elongate joints includes several aligned points; thus, the geocell can be expanded into a honeycomb-shaped three-dimenmsional confinement structure, and cells are formed for containing backfill therein. Because the plastic plates have rough surfaces, the backfill retaining capability has been significantly increased.
