Method for rectifying deviation of power transmission line tower in coal mine goaf
The invention provides a correction method for a power transmission line tower in a coal mine goaf, and belongs to the technical field of power transmission line foundation adjusting.The method comprises the steps that according to the actually measured settlement value of a tower leg foundation, a steel tower foot structure completely matched with a correction tower leg is designed and manufactured, and stay wires are arranged on the periphery and the bottom of the tower to be corrected for protection; a hoisting connecting plate is installed through a bolt of a connecting plate at the joint of a tower leg main material, after the tower leg is lifted, a newly-machined tower foot structure is replaced, finally, the tower leg main material is connected through a high-strength bolt, the tower bolt is tightened again after installation is completed, and the inclination rate of the tower is measured again. The method is wide in technical adjustment range, particularly suitable for deviation rectification of large displacement caused by settlement of a tower foundation, free of influence on an original tower structure and the out-buckling length of an original foundation bolt, high in practicability and remarkable in deviation rectification effect.
本发明提供一种煤矿采空区输电线路杆塔纠偏方法，属于输电线路基础调整技术领域，所述方法根据塔腿基础实测沉降值，设计和制造与纠偏塔腿完全匹配的钢制塔脚结构，在待纠偏的杆塔四周和底部设置拉线保护，利用塔腿主材接头处连接板的螺栓安装起吊连接板，抬起塔腿后，更换新加工的塔脚结构，最后通过高强度螺栓与原杆塔塔腿主材连接，安装完成后复紧杆塔螺栓，复测杆塔倾斜率。本发明技术调节范围广，尤其可适用于杆塔基础发生沉降大位移的纠偏，对原杆塔结构不产生影响，不影响原地脚螺栓的出扣长度，且可实施性强，纠偏效果显著。
