[0028] Example 1:
[0029] by figure 1 , figure 2 , image 3 It can be seen that a drainage anchor rod includes an anchor bar or cable 4 connected with an external anchor steel plate. The anchor bar or cable 4 is covered with a geobag 7, and the inside of the geobag 7 and the outside of the geobag 7 are respectively poured with impervious concrete And permeable concrete to form an anchor rod including impervious reinforced concrete anchor 5 and permeable concrete anchor 6; the outer anchor steel plate 9 and the anchor bar or anchor cable 4 are poured with impervious concrete and permeable concrete to form the outer anchor Pier 10.
[0030] In order to improve the bite force between the anchor solid and the rock and soil, the geobag 7 of the present invention is provided with a bulging pocket 8 as an anchor rod upside down. The bulging pocket 8 has a sharp top corner and a bottom connected with the geobag. Cone body, the height of the cone body is 10 cm ~ 20 cm, the height of the...
