Method and device for reinforcing ecological restoration backfill area of mining area for land improvement
The invention discloses a mining area ecological restoration backfill area reinforcing method and device for land renovation in the technical field of ecological restoration, and the method comprises the following steps: 1, foundation pit opening: excavating a foundation pit in a restoration area by utilizing excavating equipment, enabling the foundation pit to be circular, pumping accumulated water in the foundation pit by utilizing a water pump after the foundation pit is excavated, and enabling the foundation pit to be circular; and the depth of accumulated water in the foundation pit does not exceed 20 centimeters. The outer end of the movable conical rod is inserted into a soil layer on the side face of the foundation pit, and after the movable conical rod moves, concrete in the injection cylinder is continuously pushed and pressed, so that the concrete flows into a backfill layer through a conveying hole of the movable conical rod and a side hole in the side face of a sleeve, and it is guaranteed that the concrete is conveyed into the backfill layer after backfill is completed; the fixing effect in the backfill layer is improved, the structural stability of the backfill layer is guaranteed, collapse of the backfill layer caused by factors such as rainwater is avoided, the stability of the backfill layer is greatly improved, the collapse probability is reduced, the ecological restoration effect is improved, and the use effect is good.
本发明公开了生态修复技术领域的一种国土整治用开采区生态修复回填区域加固方法及装置，包括以下流程：第一步、基坑开设：利用挖掘设备在修复区域挖掘基坑，并使得基坑为圆形，在基坑挖掘后利用水泵进行基坑内积水的抽吸，使得基坑内积水深度不超过二十公分。本发明通过使得活动锥杆外端插入基坑侧面的泥土层中，并在活动锥杆移动后，继续推压注入筒中的混凝土，使得混凝土通过活动锥杆的输送孔和套管侧面的侧孔流入回填层内部，使得回填完毕后保证混凝土输送至回填层内部，提高回填层内部的固定效果，保证回填层的结构稳定，避免随着雨水等因素造成的回填层塌陷，大大提高回填层的稳定性，减小塌陷几率，提高生态修复效果，使用效果好。
