The soil nailing system supporting is a new supporting technology developed in recent years used for soil slope stability and the excavation.
The installation &test requirements in soil nailing field
With the deep understanding of soil nailing support and the level of the craft that make rise, the soil nails test standard need to be perfect:
1) Qualified soil nails must consider each part of the anchor rod, parts after comprehensive conclusion, can not be separated, or soil nails will appear the testing Disciplines are qualified, and the comprehensive result is unqualified;
2) testing standard of soil nails accessories need never below the yield strength to not less than the actual rod body breaking strength. If you can't meet the requirements of the above two aspects, under the condition of high stress and large deformation of surrounding rock, soil nails support can not play a proper role, and can not play a part in pressure relief effect, can't satisfy the project need, there will be huge hidden trouble.So must be used in high stress conditions such as strong soil nail, attaches great importance to the anchor production quality, to give full play to the anchor supporting role.
To stabilize the whole ground by producing resistance against collapse using reinforcement materials such as soil nails, or by protecting the surface of cut slopes and unstable natural slopes.
