Protecting Technique by Shotcrete-anchor-mat for Deep Excavation of Tall Building

The shotcrete-anchor-mat reinforcement is a new protecting technique for tall building foundation-pit. It gives a new design and construction approaches for deep excavation based on the basic principle,design calculation, engineering constructions and so on. It is proved that is reliable in technique, quick in construction, low in construction cost. This technique will have a wide landscape of development in the future.
