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
  • 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.
  • Referring to FIG. 7, a first infill retained geocell 3 of the above structure consists of plastic plates 31. The plastic plates 31 have smooth surfaces therefore friction between the retained geocell 3 and backfill, which is contained in cells 32 formed between the plastic plates 31, is too weak to prevent the backfill from being washed away from the retained geocell 3.
  • Referring to FIG. 8, a second infill retained geocell 4 of the above structure consists of plastic plates, on which diamond-shaped veins 41 are formed by means of an embossing roller such that the friction between the retained geocell 4 and the backfill increases slightly. 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.
  • SUMMARY
  • 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.
  • BRIEF DESCRIPTION OF THE DRAWINGS

  • FIG. 1 is a perspective view of the textured geocell for retaining backfill in geotechnical structure in the present invention,
  • FIG. 2 is a perspective view of the textured geocell for retaining backfill in the present invention, in stretched honeycomb shape,

  • FIG. 4 is a view showing the second usage of the textured geocell of the present invention,
  • FIG. 5 is a view showing the third usage of the textured geocell of the present invention,

  • FIG. 8 is a perspective view of the second conventional geocell for retaining backfill in geotechnical structure as described in Background.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • 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.
  • Referring to FIG. 3, several textured geocells of the present invention are expanded into honeycomb shape, filled with backfill 2, and stacked up for use as a retaining wall or in a construction foundation.
  • Referring to FIG. 4, several textured geocells of the present invention are positioned side by side on an unstable slope in a mountainous area, expanded into honeycomb shape, and filled with backfill 2. Furthermore, trailing plants are planted on the fill 2. Because the plastic plates have rough finishes 11 with irregular projections, the filled 2 will be retained in the cells 12, and wash-away of the backfill 2 will be prevented when there is rain. And, the trailing plants on the backfill 2 will grow to help hold the backfill 2 in position. Consequently, the unstable slope will be strengthened, and stones are prevented from falling.
  • Referring to FIG. 5, several textured geocells of the present invention are positioned side by side on the ground, stretched into honeycomb shape, and filled with backfill 2, and then plants are planted on the backfill 2 to make green. Because the plastic plates have rough finishes 11 with irregular projections, the backfill 2 can be effectively retained in the cells 12, and strength of the ground increased. Consequently, the ground can remain in good shape even if people run thereon, and wash-away of the backfill 2 will be prevented when there is rain, and the trees and plants will grow well.
  • 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.
  • From the above description, it can be easily understood that the textured geocell of the present invention has better retaining capability than the conventional ones as described in Background.
