| 摘要 |
The present invention relates to a nail structure for soil nailing comprising a plurality of nails inserted into the ground in series; and a front plate for finishing the tip end of the nails. Both ends of the rod-shaped body of the nail are twisted in different directions to improve friction with the ground and rigidity. The present invention facilitates transportation and handling of the nail by lightening the nail and enables workers to safely work; is environmentally friendly by reducing the cross section to be smaller than a circular cross section and saves on raw steel materials; provides high rigidity by increasing the friction between the nail and the ground; and firmly stabilizes structures built on a rock bed or on the ground by improving the binding forces. |
