Prefabricated and cast-in-place combined anchorage foundation enclosure structure and construction method
The invention belongs to the technical field of suspension bridge anchorage construction, and particularly relates to a prefabricated and cast-in-place combined anchorage foundation enclosure structure and a construction method.The prefabricated and cast-in-place combined anchorage foundation enclosure structure comprises prestressed high-strength concrete sheet piles and a cast-in-place underground diaphragm wall; the prestressed high-strength concrete sheet piles are located on the outer side of the cast-in-place underground diaphragm wall. According to the prefabricated and cast-in-place combined anchorage foundation enclosure structure and the construction method, a traditional cast-in-place concrete underground diaphragm wall is partially replaced with the prestressed high-strength concrete sheet piles, the foundation scale is reduced, and materials and the construction cost are saved; by optimizing pile foundation arrangement, the application risk caused by infirm joints is avoided, continuous and synchronous construction is conducted on the anchorage enclosure structure in the guide groove, and the construction period is further shortened.
本发明属于悬索桥锚碇施工技术领域，尤其涉及一种预制、现浇联合锚碇基础围护结构及施工方法，所述预制、现浇联合锚碇基础围护结构包括预应力高强混凝土板桩和现浇地下连续墙，所述预应力高强混凝土板桩位于现浇地下连续墙的外侧。本发明提供一种预制、现浇联合锚碇基础围护结构及施工方法，使用预应力高强混凝土板桩部分替代传统现浇混凝土地下连续墙，减小了基础规模，节约材料和施工造价；通过优化桩基排布避免了接头不牢固所带来的应用风险，在导槽内对锚碇围护结构进行连续同步施工，进一步节约工期。
