Embodiment Construction
[0015] Below in conjunction with the accompanying drawings, the station roof of the present invention, bottom beam (5) and inner column (4) are connected by shear pin (9), and the inner column end adopts the replacement mode. The specific implementation method is described:
[0016] according to Figure 1-3 , the present invention proposes an assembled monolithic underground structure that can replace the easily damaged parts (6) of prefabricated columns, including: prefabricated roof (1), prefabricated floor (3), prefabricated columns (4), prefabricated beams (5), Shear pin (9).
[0017] Specifically, the prefabricated side walls (2), the prefabricated floor (3), and the prefabricated roof (1) are rationally optimized, and the connection positions are connected by grouting sleeves (7) to ensure rigid connection at the connection positions. The prefabricated top and bottom beams (5) and the prefabricated columns are provided with pin holes (8), and replaceable parts are prov...
