Slope protection facilities are widely used for the purpose of preserving the landscape and preventing settlement of road slopes, mountainous areas, riversides / floors, and seas (shore erosion sites).

As a slope protection facility, a mat or a concrete block has been used, but the mat is not three-dimensional because it is in the form of a thin sheet, so the stiffness against the settlement is weak and the loss is severe.

In addition, the slope protection facility has a disadvantage of not being able to create a long-term vegetation environment due to difficult rooting, and the concrete block has a heavy weight, which is poor in handling and constructability (requiring a large number of manpower and large equipment) and not being environmentally friendly.

In order to solve this problem, a geo cellular (geo cellular) has been developed and used.

Geocell is a reinforcing material for civil engineering used for reinforcing soft ground. It is a three-dimensional honeycomb-type high density polyethylene (HDPE) reinforcing material manufactured by ultrasonically welding several strips having a certain width at regular intervals.

Geocell is constructed to have a three-dimensional structure by unfolding a unit body fused to both ends by overlapping at least two strips, and has the characteristic of exerting an effective particle confinement effect by a three-dimensional feature.

In the conventional geocell, a method of connecting a plurality of geocell units with a cable tie when assembling and constructing is used.

However, cable ties are not manufactured exclusively for geocells, so their strength is weak to bind them. Therefore, since the cable tie is released or disconnected, there is a limitation in that the slope of the slope collapses because the connection of the geocells is not solid in some or all sections of the slope.

In addition, it is troublesome for the worker to fix the cable tie by rotating it one unit by turning it into unit geocells, and it is difficult to bind the geocell with cable ties in a work environment where it is difficult for the operator to support themselves during slope construction. There is this.

Accordingly, there has been a need for a geocell connector capable of withstanding the external force applied to the geocell through the geocell dedicated connector and improving the connection strength between the geocells.

Therefore, in order to solve the conventional problems, the present invention is configured to form a connection hole at both ends of the geocell, and a geocell-only connector configured to bind the geocell unit through the connection hole. Therefore, it is an object to be able to increase the connection strength between the geocell units.

In addition, the present invention is configured to be rotated so that the shape of the direction in which the geocell connector is inserted into the connection hole is different from the shape of the direction after insertion.
