According to construction quality, soil nail wall, as retaining structure, should meet regular requirement of strength, deformation, stability and durability, etc. Especially in deep foundation pit excavation, control and restraint of deformation is more important.
So, construction process should combine with local inspection. Through measured data, geological condition will be explored constantly and then direct construction for next step.
During soil nail wall construction, following tips should be tested to ensure construction quality.
1. Inspection of raw materials.
2.Inspection of grouting strength and sprayed concrete strength.
3. Thickness inspection of sprayed concrete.
4. Soil nail
