Underwater operation reinforcing method for glass fiber sleeve
The invention discloses a glass fiber sleeve underwater operation reinforcement method in the field of pier column reinforcement. The method comprises the following steps: S1, pier column surface treatment: carrying out surface treatment on different types of pier columns, including removal of microorganisms on the surfaces of the pier columns, removal of loose concrete, treatment of the rusted surface of steel and cleaning of mud at the bottoms of the pier columns; S2, pretreatment of the glass fiber sleeve: injecting plate glue into a lock catch groove of the sleeve, opening the sleeve and wrapping the pier columns, according to different projects, enabling the length of the sleeve to extend 50-60 cm above and below a damaged area respectively, temporarily fixing the sleeve by using a fastening belt, and fastening a lock catch of the sleeve by using a stainless steel self-tapping screw every 15 cm; according to the method, repairing is completed by selecting a high-strength epoxy grouting material and a GRP sleeve, and the method is effective for all types of pier columns; the corrosion resistance is good, and future structural damage is prevented; the investment is only needed for a time, and long-term maintenance is avoided; a cofferdam does not need to be built, the construction difficulty is low, the navigation channel safety risk is reduced, and use by people is facilitated.
本发明公开了墩柱加固领域的一种玻纤维套筒水下作业加固方法，包括以下步骤：S1：墩柱表面处理：对不同类型的墩柱进行表面处理，包括清除墩柱表面的微生物、除去松散的砼、处理钢材锈蚀表面和清理墩柱底部的泥浆；S2：玻纤套筒预处理：在套筒的锁扣槽内注入板材胶，将套筒撑开并包裹墩柱，根据不同项目，套筒的长度是在损坏区域上下各延长50‑60cm，使用紧固带临时固定套筒，每隔15cm处，用不锈钢自攻螺丝紧固套筒锁扣处。本发明中，通过选用高强度环氧灌浆料和GRP套筒来完成修复，对所有类型的墩柱都有效；防腐性能好，预防未来结构破坏；一次性投入，免长期维护；且不需要搭建围堰，施工难度低，降低航道安全风险，有利于人们的使用。
