Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of station construction, in particular to a shared pile structure for an assembled station main body and auxiliary entrances and exits. Background Art
[0002] Prefabricated station construction technology offers significant advantages in improving project quality, increasing construction efficiency, reducing construction risks, and reducing labor requirements. Piled-arch stations, in particular, are gradually being adopted in rail transit construction. Due to construction limitations, prefabricated components cannot be placed closely alongside shared retaining structure piles in pile-supported prefabricated stations. A certain amount of assembly space is required, and after assembly, the prefabricated station is backfilled with plain concrete. When station entrances and exits share piles with the main structure, the prefabricated station is subject to horizontal forces transmitted from the attached steel supports. Because prefabricated stations are assembled from lateral rings, uneven horizontal loads can cause relative displacement and deformation at the joints between the rings, significantly impacting the structural load. At the interface between the main structure and its accessories, reasonable measures must be taken during the pile breaking process to resist lateral soil and water pressure and overload from the main structure, while also ensuring that soil does not fall into the backfilled fertilizer trough on the main structure, compromising construction safety.

[0004] Furthermore, the top pressure beam is located at a position on the common enclosure structure corresponding to the second steel support, and the top pressure beam is in an inverted L shape.
[0005] Furthermore, the top pressure beam, the common enclosure structure and the second steel support form a stable force-bearing system, ensuring the stability and safety of the pile construction, while preventing the backfill soil above the main body from falling.
