Textured geocell

Abstract

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.

Description

REFERENCE TO RELATED APPLICATIONS [0001] This Patent Application is a Continuation-in-Part Application based on U.S. patent application Ser. No. 11 / 024,694, filed on 30 Dec. 2004, currently pending.BACKGROUND OF THE INVENTION [0002] 1. Field of the invention [0003] 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. [0004] 2. Brief Description of the Prior Art [0005] 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 range...

AI Technical Summary

Benefits of technology

[0011] 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.

Problems solved by technology

However, the asperity height of the embossed pattern is still not enough, usually lower than 0.3 mm.

Consequently, the friction between the retained geocell 4 and the backfill still is not large enough to prevent the backfill from being washed away from the retained geocell 4.

The manufacturing cost of the texturized cell material will increase because rollers have to be pressed against and moved along the plate-shaped main body in addition to the extrusion step.

Consequently, backfill can't closely fit in the space between the regular projections, and the friction between the texturized cell material and the backfill isn't large enough to prevent the backfill from being washed away from the cell material.
