Structure for reinforcing and repairing wharf pile foundation by comprehensively adopting basalt fibers and construction method
The invention discloses a structure for reinforcing and repairing a wharf pile foundation by comprehensively adopting basalt fibers and a construction method.The structure comprises basalt fiber longitudinal ribs, basalt fiber sleeves, sealing rubber strips and a grouting material layer, the basalt fiber longitudinal ribs are implanted into the bottom of a damaged beam, and the free ends of the basalt fiber sleeves and the free ends of the basalt fiber longitudinal ribs are both arranged on the outer side of the pile foundation; the sealing rubber strips are arranged at the bottoms of the pile foundation and the basalt fiber sleeve, and a cement-based grouting material layer is poured between the pile foundation and the basalt fiber sleeve. The construction method comprises the following steps: carrying out surface treatment on the damaged beam bottom; roughening the surface of the pile foundation; basalt fiber composite bars are constructed; mounting a basalt fiber sleeve and a sealing rubber strip; and pouring a cement-based grouting material. Reinforcing and repairing are completed by selecting the basalt fiber longitudinal ribs and the basalt fiber sleeves, and the method is not only suitable for wharf pile foundations, but also effective for hydraulic structure pile foundations; after the wharf pile foundation is reinforced and repaired through the method, re-repairing is not needed, and the pile foundation maintenance cost is saved.
本申请公开了综合采用玄武岩纤维加固修复码头桩基的结构及施工方法，该结构包括：植入受损梁底的玄武岩纤维纵向筋、玄武岩纤维套筒、密封胶条及灌浆料层，玄武岩纤维套筒及玄武岩纤维纵向筋的自由端均设置在桩基外侧，密封胶条设置在桩基及玄武岩纤维套筒的底部，在桩基与玄武岩纤维套筒之间灌注水泥基灌浆料层。该施工方法，包括：对受损梁底进行表面处理；桩基表面粗糙处理；玄武岩纤维复合筋施工；安装玄武岩纤维套筒及密封胶条；灌注水泥基灌浆料。本申请通过选用玄武岩纤维纵向筋、玄武岩纤维套筒来完成加固修复，不仅适用于码头桩基，对于水工结构桩基基础皆有效；采用本申请对码头桩基加固修复后，无需进行再修补，节约桩基维护成本。
