Anti-scouring underwater pile foundation structure
The invention relates to an anti-scouring underwater pile foundation structure, and belongs to the technical field of bridge engineering. A protective sleeve of the anti-scouring underwater pile foundation structure is of a barrel structure formed by splicing and combining a plurality of splicing barrels; a concrete pile is filled and poured in the protective sleeve; a positioning groove which is used for installing a positioning block is formed in the outer edges of the splicing barrels, a high-strength steel wire bundle is arranged on the end surface of the positioning block, and the high-strength steel wire bundle extends into the poured concrete pile; and a positioning groove bottom hole through which the high-strength steel wire bundle passes is formed in the positioning groove. According to the anti-scouring underwater pile foundation structure, the structure is different from an existing protection thought of reinforcement after discovery, the protective sleeve is assembled and combined to the upper end surface of the pile foundation in the concrete pile foundation pouring process, the possibility that the underwater pile foundation is abraded and damaged is fundamentally avoided, and the pile foundation which is expected to be located below a riverbed can be reinforced, so that the problem that the pile body is exposed to be scoured and abraded due to the riverbed position change is prevented.
本发明涉及一种防冲刷水下桩基结构，属于桥梁工程技术领域。防冲刷水下桩基结构的保护套筒由若干个拼接筒体相互拼接组合形成筒体结构；保护套筒内填充浇筑混凝土桩；所述的拼接筒体的外缘设有用于安装定位块的定位凹槽，定位块上的端面设有高强钢丝束，高强钢丝束延伸至浇筑的混凝土桩内；定位凹槽内设有供高强钢丝束穿过的定位凹槽底孔。本发明提供的防冲刷水下桩基结构，结构不同于现有发现后加固的保护思路，而是在混凝土桩基浇筑过程中将保护套筒拼装结合到桩基上端表面，从根本上避免了水下桩基磨蚀损伤发生的可能，并可以加固预期处于河床以下范围的桩基，从而防止河床位置变化导致桩身外露遭到冲刷磨蚀的问题。
