Detailed Description

The utility model will be further described with reference to the accompanying drawings in which:

as shown in fig. 1 and 2, a geocell for slope protection construction includes a plurality of beads 1, the plurality of beads 1 being connected to each other at a plurality of junctions to form a plurality of cells, and at each junction, two or more adjacent beads 1 of the plurality of beads 1 are inserted into each other by an insert 3. The rib belt 1 can be made of PP, PE or PET, and the length of the rib belt 1 is selected according to design specifications. At each joint, adjacent strips 1 of the plurality of strips 1 are aligned and formed with slits 2 penetrating the plurality of adjacent strips 1, the slits 2 extending in the longitudinal direction of the plurality of adjacent strips 1. And the inserts 3 pass through the slits 2 in a staggered manner in order to insert a plurality of adjacent ribs 1 together.

The plug-in components 3 are made of U-shaped stainless steel wires, the diameter of each steel wire is 1-4mm, the plug-in components 3 are made of stainless steel materials, the rusting speed can be delayed, and the service lives of the plug-in components 3 and the geocell are prolonged. The specific diameter value of the plug-in 3 is selected according to the tensile resistance, and the larger the tensile resistance is, the larger the diameter of the selected steel wire is. The length of the insert 3 is 1.5-3 times the height of the rib belt. The insert 3 is inserted along the slit 2 of the two strips 1, and the two upright parts 32 of the insert 3 are sequentially inserted through the slit 2 at intervals. The two upright parts 32 of the insert 3 are fixedly connected near the lower end of the rib belt 1, so as to prevent the insert 3 from falling off from the rib belt 1. Because the length of the plug-in component 3 is greater than the height of the rib belt 1, the plug-in component 3 is longer than the upright parts 32 outside the rib belt 1 and is bent, the bending angle is not less than 90 degrees, the bending directions of the two upright parts 32 are opposite, the upright parts 32 are bent to form the bent parts 31, and the two bent upright parts 32 penetrate into the geocell after being bent (as shown in fig. 3).

The fixing mode of the lower end of the plug-in unit 3 has various options, and can be fixed by welding or gluing or fixed and connected by a fixing piece. The preferred embodiment of the present invention is the 8-shaped fixing ring 4, and the connection method of the 8-shaped fixing ring 4 is as follows: because two holes of the 8-shaped fixing ring 4 are right opposite to two vertical parts 32 of the plug-in 3, after the plug-in 3 penetrates into the cutting seam 2, the two vertical parts 32 respectively penetrate into the holes of the 8-shaped fixing ring 4, the 8-shaped fixing ring 4 is pushed along the plug-in 3, the 8-shaped fixing ring 4 is tightly attached to the rib belt 1, then the plug-in 3 is bent, and the bent plug-in 3 provides support for the 8-shaped fixing ring 4 to prevent the 8-shaped fixing ring 4 from falling off.

As shown in fig. 4, a concrete slope protection structure, this slope protection 5 structure contains the above-mentioned geotechnological check room that is used for bank protection 5 to be under construction, and this scheme is applicable to the construction scene that the slope is less than 45 degrees. During construction, firstly, the slope body is cleaned and leveled, and then the slope body is tamped. And stretching the geocell in place along the slope body, and paving the geocell on the slope body. The fixing pins are driven into the periphery of the geocell so as to fix the geocell and prevent the geocell from retracting. If the area of the geocell is large, a proper number of fixing pins are also required to be driven into the inner position of the geocell, so that the geocell can be uniformly extended in place. It should be noted that when the geocell is laid, the bent section of the insert 3 is positioned at the bottom and clings to the slope. And then, injecting concrete into the grids of the geocell to fill the grids with the concrete, finally, carrying out leveling operation on the surface of the concrete, and finishing construction after maintenance is finished. After the concrete is solidified, the insert 3 is wrapped in the concrete, namely, the reinforcing steel bars are added into the concrete, so that the connection strength of the concrete and the geocell can be improved. Compared with the conventional slope body, the slope body has higher strength and is not easy to crack.
