1. The top shield machine is capable of long-distance propulsion 2. The equipment adopts double hinge to facilitate deviation correction, and can perform small radius turning and three-dimensional turning 3, fast tunneling speed. Because pipe jacking can be carried out, compared with shield machine, cement pipes are transported in the pit during construction, and segment assembly machine is not required for assembly, so the tunneling speed is significantly accelerated 4. It can be started in sections. The starting well and receiving well occupy a small area, which is especially important in urban construction 5. Low construction cost. Compared with the pure shield, the top shield construction significantly reduces the cost and has better economical applicability.
