Bridge prefabricated drainage device and construction method thereof
The invention discloses a bridge prefabricated drainage device and a construction method thereof, the bridge prefabricated drainage device comprises: a water falling opening cup, the top of which is in an open state and the bottom of which is provided with a water outlet; the first hollow pipe is communicated with the water outlet of the water falling cup; the second hollow pipe is arranged outside the first hollow pipe in a sleeving manner, so that a mounting area for mounting a drainage pipe is formed between the first hollow pipe and the second hollow pipe; and the water stop steel ring is arranged on the second hollow pipe, so that the second hollow pipe and the water stop steel ring jointly serve as a vertical anti-seepage structure for preventing rainwater from infiltrating downwards along the outer wall of the prefabricated drainage device. By installing the prefabricated drainage device at the drainage hole and forming the prefabricated drainage device and the cast-in-place structure at a time, the rainwater grate can be directly installed through the prefabricated drainage device, the rainwater grate can be installed without digging asphalt in the later period, the integrity of the cast-in-place structure cannot be damaged, the bridge construction quality can be effectively improved, and the problems of leakage and water dripping of the drainage hole in the bridge bottom can be solved.
本发明公开了一种桥梁预制泄水装置及其施工方法，所述桥梁预制泄水装置包括：水落口杯，顶部呈开放状态，底部设置有出水口；第一空心管，与水落口杯的出水口连通；第二空心管，套设在第一空心管外，使得第一空心管与第二空心管之间形成用于安装排水管的安装区；止水钢环，设置在第二空心管上，使得第二空心管与止水钢环共同作为防止雨水沿预制泄水装置外壁下渗的竖向防渗结构。通过将预制泄水装置安装在泄水孔处，与现浇结构一次成型，即能利用预制泄水装置直接进行雨水篦子的安装，后期无需开凿沥青来安装雨水篦子，不会破坏现浇结构的整体性，能有效提升桥梁施工质量并解决桥底泄水孔渗漏滴水的问题。
