Textured geocell

a geocell and textured technology, applied in soil conditioning compositions, excavations, applications, etc., can solve the problems of insufficient friction between the retained geocell b>4/b> and the backfill, and the height of the embossed pattern is still not enough to prevent the backfill from being washed away, so as to achieve the effect of significantly increasing the retaining capacity of the backfill

embodiment 1

[0018] Referring to FIGS. 1 and 2, a preferred embodiment 1 of a geocell for retaining infill in geotechnical structure includes several plastic plates with rough finishes 11 with irregular projections on both sides. Every two adjacent plastic plates are connected together at several spaced apart elongate joints, each of which elongate joints includes several aligned points, and in turns, the present geocell will be in the shape of a honeycomb, which includes many cells 12 for containing backfill therein, when it is expanded, as shown in FIG. 2; welding with ultrasonic wave or other methods can be used for connecting the plastic plates together. Because the plastic plates have rough finishes 11 with irregular projections, the backfill 2 can be effectively retained in the textured infill retained geocell 1 of the present invention.

[0019] Referring to FIG. 3, several textured geocells of the present invention are expanded into honeycomb shape, filled with backfill 2, and stacked up fo...

second embodiment

[0022] Referring to FIG. 6, in a second embodiment, the plastic plates of the textured geocell 1 are further formed with several through holes 13 over them.

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

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] 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. [0003] 2. Brief Description of the Prior Art [0004] 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. [0005] Referring to FIG....
