Bridge foundation structure with prefabricated shell and construction method thereof
The invention provides a bridge foundation structure with a prefabricated shell and a construction method thereof.The bridge foundation structure comprises a foundation body structure and a protection structure, the protection structure is arranged on the outer side of the foundation body structure in a surrounding mode, and the foundation body structure comprises a pile foundation unit, a bearing platform and a pier column which are sequentially connected from bottom to top; the pile foundation unit comprises two pile foundations arranged at intervals in the length direction of the bearing platform, the bearing platform is fixedly connected to the tops of the pile foundations, the pier column is fixed to the top of the bearing platform, the protection structure comprises a pile foundation shell, a bearing platform shell and a pier column shell, and the pile foundation shell is used for wrapping the pile foundations and is fixedly connected with the pile foundations; the bearing platform shell is used for wrapping the bearing platform and fixedly connected with the bearing platform, and the pier column shell is used for wrapping the pier column and fixedly connected with the pier column. Therefore, the prefabricated shell structure with high impermeability is arranged on the outer surface of the bridge foundation to enhance the crack resistance of the bridge foundation in the marine environment, and the prefabricated shell structure is connected with the common concrete structure through the steel bars, so that cooperative deformation stress can be ensured.
本发明提供一种带预制外壳的桥梁基础结构及其施工方法，包括基础主体结构及防护结构，防护结构环绕设置于基础主体结构的外侧，基础主体结构包括自下至上依次连接的桩基单元、承台及墩柱，桩基单元包括两根沿承台的长度方向间隔排布的桩基，承台固定连接于桩基的顶部，墩柱固定于承台的顶部，防护结构包括桩基外壳、承台外壳及墩柱外壳，桩基外壳用于包覆桩基并与桩基固定连接，承台外壳用于包覆承台并与承台固定连接，墩柱外壳用于包覆墩柱并与墩柱固定连接。如此通过在桥梁基础的外表面设置具有高抗渗性的预制外壳结构，以增强海洋环境中桥梁基础的抗裂性，并将预制外壳结构与普通混凝土结构通过钢筋连接，可保证协同变形受力。
