摘要
以S903资兴至永兴青界山公路东江大桥工程为背景,针对裸岩河床钻孔灌注桩钢护筒筒底口卷边和串浆等问题,采用了钢护筒外植筋做辅桩预固定钢护筒,钢护筒外套套筒和套筒内浇筑水下混凝土的处治方案,实践证明,该处治方案可靠有效,可为今后类似工程的施工提供借鉴。
Taking east river bridge engineering of S903 Zixing-Yongxing Qingjie mountain highway as the background, in light of uncovered river-bed bored pile steel casing bottom curling and grout leaking problems, the paper adopts steel casing reinforcement as assistant pile pre-fixing steel casing, and introduces external steel casing and internal grouting concrete processing scheme. Practice proves the above-mentioned processing scheme is reliable and effective, which will provide some guidance for similar engineering construction in future.
