High bearing platform envelop enclosure for steep slope bridge border on river, and construction method
The invention discloses a high bearing platform envelop enclosure for a steep slope bridge border on a river, and a construction method. The high bearing platform envelop enclosure comprises pile foundations, a bearing platform, guard piles and an erosion protection wall, wherein the pile foundations are buried in a foundation; the bearing platform is fixedly arranged at the tops of the pile foundations; the guard piles are fixedly arranged in the position where the pile foundations are near the high side of a steep slope, of the foundation, and the tops of the guard piles are higher than thetop of the bearing platform; and the erosion protection wall is fixedly arranged in the position where the pile foundations are near one side of a river valley, of the foundation. The guard piles arearranged in the position where the pile foundations are near one side of the steep slope, of the foundation, the tops of the guard piles are higher than the top of the bearing platform, and the guardpiles are used for bearing main earth pressure of a slope, so that slope stability can be guaranteed, the excavated volume of foundation pits can be reduced, and besides, land utilization can be saved; and the erosion protection wall is arranged in the position where the pile foundations are near one side of the river valley, of the foundation, and the erosion protection wall can prevent concentrated water currents of the river valley from scouring soil mass of the pile foundations, so that horizontal deformation of bridge piers and abutments can be decreased, and the stability is increased. The high bearing platform envelop enclosure not only can prevent one sides border on the river valley, of the pile foundations from erosion by rivers, but also can reduce the excavated volume of the soil mass on one side border on the steep slope.
本发明公开了一种临河陡坡桥梁高承台围护结构及施工方法，结构包括桩基、承台、防护桩和防冲刷墙，桩基埋设在地基中，承台固定设置在桩基顶部，防护桩固定设置在桩基靠近陡坡较高一侧的地基中，防护桩的顶部高于承台的顶部，防冲刷墙固定设置在桩基靠近河谷一侧的地基。在桩基靠近陡坡一侧的地基内设置防护桩，防护桩顶部高于承台顶部，防护桩用于承担边坡主要的土压力，可以保证收坡稳定，减少基坑开挖量同时节约用地，在桩基靠近河谷一侧的地基内设置防冲刷墙，防冲刷墙能够避免河谷集中水流冲刷桩基土体，减小了桥梁墩台的水平变形，提高稳定性。该结构不仅能避免桩基临河谷一侧受到河流冲刷，还能减少临陡坡侧土体的开挖量。
