1. Preparing materials, machines and toolsGetting ready the requiired machines and tools for construction, like shovels, generators, steel drivers and so on. If the soil on the spot is rocky, the organically mixed soil need to be transported from other place for filling into the geotextile bag.
| Figure 1: the soil for filling in |
2.How to install the stocking-shaped geotextile bag Firstly,ship the filling soil by shovel onto the top of the hill. Hang down the bag from the top of the hill vertically and put the soil into the bag by conveyor belt. Than push a steel every 100cm on the bag until the bag is fully filled. Shown in figure 2-4.

3. Slope repaiingr and digging After the stoking-shaped bag is installed, go on to install the geotextiles bag. Firstly, the slope must be repaired and foundation be digged to the depth in which one bag can be holded.( see figure 5 , 6)
| | Figure 5: repairing the slope | | | | Figure 6: Digging | |
4.To install geotextile bag onto the foundation The bag which is installed to the doundation is filled with gravel soil and sealed by the binding band so that to have drainage effect. Then stack the bag in order in a vertical direction(lenthways) and push the steel onto the bag to reinforce them. (As shown in figure 7, 8,and 9).

5. Stack layer by layer When the base layer is complete, put Jianchibao project fasterner on the top, and stack the geotextile bag which is filled with organically mixed soil (as shown in pic 10). Compact the bag when each layer is finished stacking. To strenthen the connection between the bag and slope, place a bag vertically to the slope on each two levelly placed bags, ,meanwhil,dig intothe slope to hold the bag and push the steel onto it to enhance its stability.(As shown in figure 12,13) | | Figure 10 : Stack layer by layer | Figure 11: Compacting on each layer |

Firstly, place the waterproofing membrane, on which stack the bag vertically ( as shown in figure 14). Then the steels are pushed onto it to enhance connection force between the two. The waterproofing membrane plays a role of preventing water entering into the bags and slopes so as to prevent slope sliding, thus insuring the security of the structure. | Figure 14: the waterproofing membrane and the view of the bag on the top |

7.Spraying the seeds of grass Mix seeds of grass with organic fertilizer then spray them onto the slope directly( as shown in frgure 16).
