Deviation rectifying method for skewed ultra-high voltage transmission tower in coal mine subsidence area
The invention provides a deviation rectifying method for a skewed ultra-high voltage power transmission tower in a coal mine subsidence area. Wheel-passing adjacent anchor ground anchors are respectively embedded in power transmission towers on the upstream side and the downstream side; a temporary stay wire ground anchor is embedded in the skewed power transmission tower; power is cut off first, and then spacers on conducting wires between the adjacent power transmission towers on the two sides of the skewed power transmission tower are removed; grounding wire paying-off pulleys are respectively hung on the transmission towers on the upstream side and the downstream side, the conducting wires are moved into the pulleys from wire clamps, and wheel-passing temporary anchors and rubber hanging anchor ropes are arranged; a double-steel-wire-rope stay wire is arranged on the outer corner side of the skewed power transmission tower; steel wire rope sleeves are respectively connected to the front parts of the wire clamps on the upstream side and the downstream side of the skewed power transmission tower, and the internal tension of a single conducting wire is reduced to a set value; a winch is used for tightening the conducting wires through cables and wire clamping devices, the wire clamps are picked off, then the steel wire rope sleeves with the corresponding length are connected in series, and the winch is slowly loosened, so that the conducting wires are loosened to a specified length; and a tower foot IV, a tower foot I and a tower foot III are sequentially lifted. According to the method, the deviation rectification of the power transmission tower with large weight and uneven settlement can be realized.
本发明提供了一种煤矿沉陷区歪斜特高压输电铁塔纠偏方法，在上下游侧输电铁塔分别埋设过轮临锚地锚；在歪斜输电铁塔埋设临时拉线地锚；先停电，然后拆除歪斜输电铁塔两侧的相邻输电铁塔之间导线上的间隔棒；在上下游侧输电铁塔分别挂导地线放线滑车，将导线从线夹内移至滑车内，并设置过轮临锚和挂胶锚绳；在歪斜输电铁塔外角侧设置双钢丝绳拉线；在歪斜输电铁塔上下游侧的线夹前分别连接钢丝绳套，将单根导线的内拉力降低到设定值；利用绞车，通过缆绳和卡线器收紧导线，摘开线夹后串接相应长度的钢丝绳套，缓慢回松绞车，使导线松至规定长度；依次对塔脚四、塔脚一和塔脚三进行提升作业。该方法可以实现重量大、沉降不均匀输电铁塔的纠偏。
