Power transmission tower settlement correction method
The invention discloses a power transmission tower settlement deviation rectifying method, relates to the technical field of power transmission tower deviation rectifying, solves the problems that deviation rectifying construction of an existing power transmission tower is difficult, and the settlement risk still exists, improves the firmness and stability of a plate type foundation, and reduces the cost, and adopts the specific scheme as follows: arranging four-side protection stay wires for the power transmission tower; foundation pits are sequentially excavated below the four corners of a plate type foundation at the bottom of a to-be-jacked supporting leg of the power transmission tower, after each foundation pit is excavated, a spiral anchor is installed in the foundation pit, a steel beam is installed at the top end of the spiral anchor, a hydraulic jack is placed on the steel beam to support the corners of the plate type foundation, and then subsequent foundation pit excavation and corner supporting are conducted; after the plate-type foundation is jacked to the specified height through the hydraulic jack, the hydraulic jack is replaced with the cushion block; and after all the hydraulic jacks are taken out, grouting and backfilling are conducted in the foundation pit.
本发明公开了一种输电塔沉降纠偏方法，涉及输电塔纠偏技术领域，解决了现有输电塔纠偏施工难且仍存在沉降风险的问题，提高了板式基础的牢固性和稳定性，降低了成本，具体方案如下：对输电塔设置四方防护拉线；在输电塔待顶升支腿底部的板式基础的四个边角下方依次开挖基坑，每个基坑开挖完成后先在基坑内安装螺旋锚，在螺旋锚的顶端安装钢梁，并在钢梁上放置液压千斤顶以支撑板式基础边角，然后再进行后续基坑的开挖及边角支撑；通过液压千斤顶将板式基础顶升至指定高度后利用垫块替换液压千斤顶；待所有液压千斤顶取出后，在基坑内灌浆并回填。
