Repair method for port wharf steel pipe pile
The invention relates to a repairing method for a port wharf steel pipe pile. The repairing method comprises the steps of surface treatment; the surface is coated with an epoxy zinc-rich priming coat, and the surface of the epoxy zinc-rich priming coat is polished; a first cloth layer is pasted outside the epoxy zinc-rich primer, the first cloth layer comprises first carbon fiber cloth and first glass fiber cloth which are glued, and the outer side face of the first carbon fiber cloth is attached to and combined with the surface of the epoxy zinc-rich primer; the first glass fiber cloth is coated with a first anti-corrosion coating and dried; the first anticorrosive coating comprises the following components: 80-100 parts of a waterborne polyurethane emulsion, 60-70 parts of glass flakes, 5-8 parts of a coalescing agent, 1-3 parts of a flatting agent, 1-2 parts of a defoaming agent and 1-2 parts of a thickening agent. The effects of seawater corrosion resistance, permeation resistance, acid and alkali resistance, salt mist resistance, mechanical property improvement and the like can be achieved through simple design and technology, repairing of the steel pipe pile can be achieved, and corrosion prevention and reinforcement of the steel pipe pile can also be achieved.
本发明涉及一种港口码头钢管桩的修复方法，包括：表面处理；在表面涂布环氧富锌底涂层，并在环氧富锌底涂层表面打磨；在环氧富锌底涂层外粘贴第一布层，第一布层包括胶接的第一碳纤维布和第一玻璃纤维布，第一碳纤维布的外侧面贴靠并结合于环氧富锌底涂料的表面上；在第一玻璃纤维布外涂刷第一防腐涂料并烘干；第一防腐涂料包括以下组分：80‑100份水性聚氨酯乳液，60‑70份玻璃鳞片，成膜助剂5‑8份，流平剂1‑3份，消泡剂1‑2份，增稠剂1‑2份。本发明采用简单的设计和工艺即可实现抗海水腐蚀、抗渗透、抗酸碱、耐盐雾和提升力学性能等功效，既可实现对钢管桩的修补，又可实现对钢管桩的防腐和加固。
