The impact of small buildings adjacent to the building. As the soil nail construction using a small step by section excavation, and in the excavation after the timely provision of soil nail and surface structure, so that the surface layer and the excavation slope close integration. Soil nails and the surrounding soil firmly bonded to the soil slope of the soil less disturbed, the impact of adjacent buildings.
Construction tools are simple and flexible construction. The equipment used for the provision of soil nails and the spraying of concrete equipment are all mobile small machinery, mobile and flexible, the required space is also small. Such machinery vibration is small, low noise, in the urban area construction has obvious superiority. Soil nailing construction speed, in the excavation process easier to adapt to different soil conditions and construction procedures.
Good economic returns. According to Western European statistics, soil nailing support than the anchor wall support program can save 10% to 30% investment in the United States, according to its soil nailing excavation patent report can save about 30% of investment. According to statistical analysis of the domestic economy 9 soil nailing works that investment can save 30% to 50%.
