Reinforcing process for composite material of power transmission tower
The invention relates to the technical field of power transmission line operation and maintenance and tower reinforcement optimization, and discloses a power transmission tower composite material reinforcement process which comprises the following steps: step 1, firstly, primarily selecting a part of cementing materials capable of being used for reinforcing a carbon fiber composite material; and 2, carrying out a cementing agent body performance test and a bonding performance test between the cementing agent and the steel material on the cementing material in the step 1. According to the reinforcing process for the composite material of the power transmission tower, the surface of the weak part of the tower material of the iron tower is coated with the special adhesive, and the carbon fiber sheet is adhered to the surface, needing to be reinforced, of the angle steel tower material, so that a part of load is transmitted to the carbon fiber sheet through the adhesive layer; by utilizing the characteristics of high strength, small density and strong plasticity of the carbon fiber composite material, the stress level of the weak part of the angle steel is reduced, the iron tower material and the carbon fiber are bonded into a whole to coordinate deformation and work together, the bearing capacity and the fatigue performance of the iron tower are improved, and the service life of the iron tower is prolonged.
本发明涉及输电线路运维及杆塔补强优化技术领域，且公开了输电铁塔复合材料加固工艺，包括以下步骤：步骤一：首先初选一部分可用于碳纤维复合材料加固的胶结材料；步骤二：对步骤一中的胶结材料进行胶结剂本体的性能试验和胶结剂与钢材之间的粘结性能试验。该输电铁塔复合材料加固工艺，通过利用在铁塔塔材薄弱部位表面涂覆特制的胶粘剂，将碳纤维片材粘贴到角钢塔材需要加固补强的表面，使一部分荷载通过胶层传递到碳纤维片材上，利用碳纤维复合材料高强度、密度小和可塑性强的特性，降低角钢薄弱部位的应力水平，将铁塔塔材和碳纤维粘接成整体，协调变形、共同工作，提高铁塔承载能力和改善其疲劳性能，延长铁塔使用寿命。
