Vertical shaft structure and construction method thereof
The invention discloses a vertical shaft structure and a construction method thereof. The vertical shaft structure comprises a supporting and blocking structure, wherein the supporting and blocking structure comprises a shield tunnel, a lining supporting structure and a long and short combined underground continuous wall. The long and short combined underground continuous wall is designed, when the bottom of the short underground continuous wall is excavated, namely, when the short underground continuous wall is suspended, the requirements of foundation bearing capacity and stability are met by means of a rock-socketed section of the long underground continuous wall; and when the bottom of the long underground continuous wall is excavated, namely, when the long underground continuous wallis suspended, the requirements of foundation bearing capacity and stability are met by means of a combined structure of the short underground continuous wall and the lining supporting structure, and astaged stress system is realized. The vertical shaft structure and the construction method thereof can be widely applied to the technical field of deep foundation pit construction.
本发明公开了一种竖井结构及其施工方法，竖井结构包括支挡结构，支挡结构包括盾构隧道、内衬支护结构和长短结合的地下连续墙。设计长短结合的地下连续墙，当开挖至短的地下连续墙底时，即短的地下连续墙吊脚时，依靠长的地下连续墙的嵌岩段来保证地基承载力和稳定性的要求，当开挖至长的地下连续墙底时，即长的地下连续墙吊脚时，依靠短的地下连续墙结合内衬支护结构的组合结构来满足地基承载力和稳定性的要求，实现分阶段受力的体系。本发明可广泛应用于深基坑施工技术领域。
