Soil nail support in subway constructionby Anna S. Optimization Specialist
Mumbai is located on Salsette Island, west coast of Maharashtra State, facing the Arabian Sea. The population in Mumbai city is about 23 million, it is a second-most populous city in India, and also one of the most populous cities in the world.
The implementation of 2 new elevated metro lines in Mumbai has been approved. This includes the 24 km Line-5 between Thane – Bhiwandi – Kalyan and the 14.5 km Line-6 between Lokhandwala – Jogeshwari – Vikhroli – Kanjurmarg.
The population in Mumbai will probably reach 30 million, but the infrastructure of urban transportation is quite hysteretic. Influenced by the geographical environment, road curves are many, and the radius of turning is small. So a series of new technologies need to be adopted to ensure the metro’s reliability and comfort.
Soil nail support in metro construction mainly reflects in the security aspect. Through self-reinforcement and combination with concrete spraying, similar gravity retaining wall will be formed to resist soil pressure behind it and then maintain the stability of the excavation face. Sinorock soil nails can be used not only for temporary support but also for the construction of permanent projects.
