Permanent and temporary combined dock wall structure and construction method thereof
The invention particularly discloses a permanent and temporary combined dock wall structure and a construction method thereof.The permanent and temporary combined dock wall structure comprises a permanent structure and a temporary structure, the permanent structure is composed of a quay wall soil retaining structure and an anchorage assembly, the quay wall soil retaining structure is a front-row continuous sheet-pile wall, and the anchorage assembly comprises an anchorage structure; the anchorage structure is connected with a bearing platform at the top of the sheet-pile wall through a steel pull rod; the temporary structure is composed of an enclosing purlin and a pre-stressed anchor rod, the enclosing purlin is arranged on the near-water side of the sheet-pile wall, the pre-stressed anchor rod is anchored in a soil layer on the back-water side of the sheet-pile wall, and one end of the pre-stressed anchor rod is connected with the enclosing purlin. The construction method comprises the following steps: constructing a dock wall main body structure pile foundation; constructing an anchorage wall, a block stone prism, a dock wall bearing platform and a steel pull rod; temporary anchor rod construction; constructing a dock bottom plate and backfilling earthwork behind the wall; the anchor rod is dismantled; deformation of the sheet-pile wall structure in the construction period can be reduced, the requirement for protection of the surrounding environment is met, meanwhile, stress of the sheet-pile wall in the use period is reduced, and meanwhile stress of the sheet-pile wall in the use period is reduced.
本发明具体公开了一种永临结合的船坞坞墙结构及其施工方法，其结构包括永久结构和临时结构，其中永久结构由岸壁挡土结构和锚碇组件组成，所述岸壁挡土结构为前排连续的板桩墙，所述锚碇组件包括锚碇结构，所述锚碇结构与板桩墙顶部的承台通过钢拉杆连接；所述临时结构由围檩及预应力锚杆组成，所述围檩设置在板桩墙临水侧，所述预应力锚杆锚固在板桩墙背水侧的土层内，其一端与围檩相连；施工方法包括：坞墙主体结构桩基础施工；锚碇墙、块石棱体、坞墙承台及钢拉杆施工；临时锚杆施工；坞底板施工及墙后土方回填；锚杆拆除；可减少板桩墙结构施工期的变形，满足对周边环境的保护，同时减小板桩墙使用期受力，同时减小板桩墙使用期受力。
