Substation equipment foundation repairing device and method
The invention belongs to the field of substation equipment foundation repair, and particularly relates to a substation equipment foundation repairing device and method. The repairing device comprises a steel chisel arranged on a concrete foundation and located above the ground plane, an I-shaped steel beam arranged above the steel chisel, hydraulic jacks arranged on the ground plane, located at the two ends of the I-shaped steel beam and used for supporting the I-shaped steel beam, and a steel wire rope sleeve connected between the steel chisel and the I-shaped steel beam. And at least one grouting pipe is arranged between each of two depth positions at the bottom of the concrete foundation and the ground plane. High polymer materials and expansive concrete are injected twice before and after the repairing device lifts the concrete foundation through the grouting pipes at different positions, filling is compact, repairing is accurate, rigidity is large, and the effect of stabilizing the concrete foundation is good; and the problems that the upper portion of the transformer substation concrete foundation is electrified, the excavation and reconstruction period is long, and large mechanical equipment cannot work are solved, non-excavation minimally-invasive foundation settlement and inclination treatment is achieved, the treatment cost is low, and rapidness and effectiveness are achieved.
本发明属于变电站设备基础修复领域，具体涉及一种变电站设备基础修复装置和方法，所述修复装置包括设置在混凝土基础上且位于地平面上方的钢钎、设置在钢钎上方的工字钢梁、设置在地平面上且位于工字钢梁两端用于支撑工字钢梁的液压千斤顶，钢钎和工字钢梁之间连接钢丝绳套，混凝土基础底部两个深度位置与地平面之间分别布置至少一根注浆管。本发明通过不同位置的注浆管并且在修复装置抬升混凝土基础前后两次注入高聚物材料和膨胀混凝土，填充密实，修复精准，钢度大，稳固混凝土基础效果好，而且解决变电站混凝土基础上部带电、开挖重建周期长、大型机械设备无法作业问题，实现非开挖微创治理基础沉降、倾斜问题，治理成本低，快速有效。
