Freeze-thaw damage treatment method for tower foundation
The invention provides a tower foundation freeze-thaw damage treatment method which comprises the following steps: 1, digging a groove at a crack, placing a plurality of small permanent magnets into a matrix magnet, injecting magnetic slurry, and adsorbing and converging the slurry between a magnetic block bracket and the wall of the crack groove; secondly, a freeze-thaw prevention and treatment structure layer is additionally arranged in the bearing platform and is composed of a plurality of small unit bodies, baffles are arranged on the upper face and the lower face of each cuboid steel cage, inwards-sunken rubber bags are arranged on the six faces of each cuboid steel cage, an electromagnet and an electromagnetic ultrasonic vibration rod are placed in the middle of each cuboid steel cage, and slurry can enter finer cracks through electromagnetic vibration under the action of alternating current, so that the cracks are filled compactly; and thirdly, a filling structure layer is additionally arranged in the bearing platform, the magnetized waste iron-ore slag is mixed with concrete to be mixed, filled and tamped in the steel cage, certain magnetism is achieved, and in the later use process of the structure, when cracks are generated through freezing and thawing, grouting is conducted in the cracks through a grouting nozzle. And the magnetic slurry is matched with the permanent magnet, the electromagnet and the magnetic substance for freeze-thaw repair, so that the filling effect is remarkably improved.
本发明提供了杆塔基础冻融损伤处理方法，其一，在裂缝处开凿凹槽，置入多个小块永磁体排列成矩阵磁体，注入磁性浆液，浆液吸附汇聚在磁块托架与裂缝槽壁之间；其二，在承台内加设冻融防治结构层，由多个小单元体构成，每个长方体钢笼上下两个面设有挡板，六个面均设有向内凹陷的橡胶囊，中间放入电磁铁，电磁超声波振动棒与交变电流作用下的电磁振动，浆液能进入更加细小的裂缝，填充密实；其三，在承台内加设填充结构层，充磁后的废弃铁矿渣掺入混凝土拌合填筑夯实在钢笼内，具有一定磁性，结构在后期使用过程中，冻融产生裂缝时，再通过注浆嘴向裂缝内注浆。利用磁性浆液配合永磁铁、电磁铁及磁性物质进行冻融行修复，填充效果显著提高。
