一种盾构管片拆除气囊辅助施工方法
By using airbag-assisted construction, pressure sensors inside and outside the airbag are used to control the air pressure to counteract the weight of the tunnel segments, enabling rapid and safe dismantling and recycling of the tunnel segments. This solves the problem of the inability to dismantle and recycle tunnel segments, reduces project costs, and achieves sustainable development.

AI Technical Summary
In existing technologies, tunnel lining segments cannot be effectively dismantled and recycled within the station area, leading to increased project costs and energy waste.
The airbag-assisted construction method is adopted. By arranging airbags on the inner circumference of the tunnel segment and connecting them to the hoisting head, the inflation volume and bonding pressure are monitored by pressure sensors inside and outside the airbags. The air pressure inside the airbags is controlled to counteract the weight of the tunnel segment, so as to achieve rapid and safe dismantling of the tunnel segment.
It enables rapid and safe dismantling of tunnel segments, facilitating subsequent recycling and reuse, reducing project costs, minimizing energy waste, and improving construction efficiency.
