Waterproof and drainage structure at elevated railway bridge column cap
The invention relates to a waterproof and drainage structure at an elevated railway bridge column cap, which comprises a water retaining ridge (10) and a drainage assembly, the water retaining ridge (10) is arranged at the top of a column cap (2) and is circumferentially closed, and the horizontal projection of the water retaining ridge (10) surrounds the horizontal projection of a vertical rail joint (5) at the top of the column cap. The drainage assembly comprises a drainage port (11) used for drainage of the area defined by the water retaining ridge (10) and a drainage pipe (12) connected with the drainage port (11). Compared with the prior art, leaked water at the joint is concentrated in a small range through the water retaining ridge, and accumulated water can be rapidly drained and prevented from flowing downwards to a waiting room due to the arrangement of the side type floor drain and the drainage pipe; the water retaining ridge and the column cap are integrally formed and are tight and seamless, and the hidden danger of water leakage is avoided; the water collecting area is open and convenient to clear and dredge; and the cost is basically not increased.
本发明涉及一种高架铁路桥柱帽处的防排水结构，包括挡水坎(10)和排水组件，挡水坎(10)设置于柱帽(2)的顶部且周向封闭，挡水坎(10)的水平投影包围在柱帽顶部垂轨向接缝(5)的水平投影外，排水组件包括用于挡水坎(10)所围区域排水的排水口(11)以及与排水口(11)连接的排水管(12)。与现有技术相比，本发明通过挡水坎将接缝处漏水集中在较小范围，侧式地漏和排水管的设置，可以快速排除积水，避免向下漫流至候车室；挡水坎与柱帽一体成型，严密无缝，无漏水隐患；集水区域开敞，清通方便；基本不增加造价。
