Treatment method for bridge pile bottom ultra-deep karst fissures
The invention discloses a bridge pile bottom ultra-deep karst fissure treatment method which comprises the following steps that S1, mountain cutting rock ballast is backfilled into a pile foundation bottom ultra-deep fissure through an original pile foundation hole till the pile foundation bottom ultra-deep fissure is backfilled to a preset position, and an adjacent pile foundation is further buried in an area adjacent to an original pile foundation; s2, the original pile foundation is continuously backfilled with concrete, and the concrete is backfilled to the rock surface of the top of the rock layer; s3, after the concrete is solidified, holes are drilled in the concrete surface, rock anchor rods are inserted and anchored through the drilled holes, and the upper ends of the rock anchor rods are exposed out of the rock surface and the concrete surface; s4, concrete continues to be poured on the rock surface and the concrete surface, a first-layer bearing platform is formed, and the first-layer bearing platform and the rock anchor rod are fixed into a whole; and pouring is continued on the first-layer bearing platform to form a second-layer bearing platform, and a ground tie beam is poured between the second-layer bearing platform and the original pile foundation. The method has the advantages of being convenient to construct, high in economical efficiency, high in treatment quality, wide in application range and high in construction operation safety.
本发明公开了一种桥梁桩底超深岩溶裂隙的处理方法，包括以下步骤：S1、通过原桩基孔口向桩基底部超深裂隙内回填开山石渣，直至回填至预设位置，原桩基临近区域还埋设有临近桩基；S2、继续向原桩基内回填混凝土，混凝土回填至岩石层顶部的岩石面处；S3、待混凝土固化之后，在混凝土面上钻孔，并通过钻孔插入并锚固岩石锚杆，且使得岩石锚杆上端露出岩石面和混凝土面；S4、继续向岩石面和混凝土面上浇筑混凝土，形成第一层承台，第一层承台和岩石锚杆固定为一体；再继续在第一层承台上方浇筑，形成第二层承台，在第二层承台和原桩基之间浇筑地系梁。本专利方法具有施工方便、经济性高、处理质量高、适用范围广及施工作业安全性高的优点。
