Fabricated reservation system of rail transit long-term extension interface and construction method

The invention belongs to the technical field of rail transit engineering, and provides an assembly type reservation system of a rail transit long-term extension interface and a construction method.The assembly type reservation system comprises a foundation pit support structure and a main body internal structure, and the foundation pit support structure and the main body internal structure can be prefabricated through composite fiber reinforced materials; the main body has the characteristics of light weight and large lateral flexural rigidity, and meanwhile, the internal structure of the main body can be provided with arc-shaped annular plates with different sizes in advance according to shield tunnels with different diameters in a long-term multi-level system line, so that the access conditions of the shield tunnels with different diameters can be met; and the inclusive reservation effect of the advanced rail transit project on the long-term multi-level system line can be realized. 本发明属于轨道交通工程技术领域，提供一种轨道交通远
