ZHANG YU / CHEN AILONG / ZHANG XIANHAI

The invention belongs to the technical field of backfill reinforcement, and particularly relates to an ore extraction ecological restoration backfill reinforcement method which comprises the following steps: S1, foundation pit opening: excavating a foundation pit in a to-be-restored and backfilled area by utilizing excavating equipment, and compacting the pit wall of the foundation pit after the excavation is completed; s2, drainage treatment, wherein water in the foundation pit is pumped out; s3, a steel casing and a steel casing base are poured, specifically, the shapes of the steel casing and the steel casing base are prefabricated through steel bars, and then pouring treatment is conducted on the steel bars; s4, a steel casing is driven, specifically, the steel casing is driven into the foundation pit; s5, steel casing base splicing is conducted, specifically, the steel casing base is placed into the steel casing so that the steel casing base can make close contact with the bottom of the foundation pit, and then edge sealing treatment is conducted on the joint of the steel casing base and the steel casing; and S6, reinforcing the steel casing, wherein a steel bar frame is erected in the steel casing. The reinforcing method is simple and convenient, the stability of ore mining ecological restoration backfill reinforcing is guaranteed, and the cost is controllable.

本发明属于回填加固技术领域，尤其为一种矿石开采生态修复回填加固方法，包括以下步骤：S1：基坑开设：利用挖掘设备在待修复回填区域挖掘基坑，在挖掘完成后对基坑的坑壁进行压实；S2：排水处理：将基坑内的水抽出；S3：浇筑钢护筒和钢护筒底座：通过钢筋预制钢护筒和钢护筒底座的外形，然后对钢筋进行浇筑处理；S4：打入钢护筒：将钢护筒打入到基坑内；S5：钢护筒底座拼接：将钢护筒底座放入到钢护筒内，使得钢护筒底座与基坑底部紧密接触，然后对钢护筒底座与钢护筒连接处进行封边处理；S6：钢护筒加强：在钢护筒内部搭设钢筋架。本发明加固方法简单便捷，保证矿石开采生态修复回填加固的稳定性，并且成本是可控的。
