The synchronous technology of shield tunneling and assembling independently developed by Shanghai Tunnel Engineering Co., Ltd. has been successfully tested recently, and the first push-and-assemble synchronous shield machine is about to go offline. In the process of tunnel construction, the shield machine using this technology will realize the parallel operation of tunneling and assembly, which will greatly improve the construction efficiency.
In the traditional shield machine construction, the construction process is generally advancing, stopping and assembling. Every time the shield machine goes forward, it needs to stop in situ, complete the assembly of a segment, and then continue the excavation. Tunnel excavation and segment assembly are carried out in series. The parallel operation of excavation and assembly can be realized by applying the push-and-push synchronization technology. Relevant simulation tests show that the push-and-push synchronization technology will greatly reduce the operation time of each ring segment of shield machine and improve the construction efficiency by 30% to 50%.
