Construction method of downstream permanent traffic bridge of hydropower station
The invention discloses a construction method for a downstream permanent traffic bridge of a hydropower station. The construction method comprises the following steps: 1, first-stage cofferdam construction; 2, construction of a first-stage bridge substructure; 3, bridge prefabrication and first-stage bridge installation; 4, filling an artificial island in the river and transferring second-stage construction equipment; 5, filling a second-stage upstream cofferdam by using the first-stage cofferdam demolition material; 6, second-stage construction equipment is transferred to the opposite bank; seventhly, the remaining part of the second-stage cofferdam is constructed; 8, a second-stage bridge lower structure is constructed, and a second-stage bridge is installed; and 9, finishing the construction of the downstream permanent traffic bridge of the hydropower station. According to the method, the first-stage cofferdam is used for filling the artificial island in the river, the parking requirement of second-stage construction mechanical equipment is met, then the first-stage cofferdam demolition materials are used for filling the second-stage cofferdam, the artificial island is communicated with a second-stage bank slope, and the equipment parked on the artificial island is transferred to a second-stage river opposite bank for second-stage remaining cofferdam filling and second-stage bridge construction. Therefore, the traffic bridge construction channel arrangement scheme is improved, and the overall construction progress is accelerated.
本发明公开了一种水电站下游永久交通桥施工方法，包括步骤：一、一期围堰施工；二、一期桥梁下部结构施工；三、桥梁预制以及一期桥梁安装；四、河中人工岛填筑以及二期施工设备转运；五、利用一期围堰拆除料填筑二期上游围堰；六、二期施工设备转运至对岸；七、二期围堰剩余部分施工；八、二期桥梁下部结构施工以及二期桥梁安装；九、水电站下游永久交通桥施工施工完成。本发明利用一期围堰填筑河中人工岛，满足二期施工机械设备停放需要，再利用一期围堰拆除料填筑二期围堰，将人工岛与二期岸坡连通，使人工岛上停放的设备转运至二期河对岸进行二期剩余围堰填筑和二期桥梁施工，如此改善了交通桥施工通道布置方案，加快了整体施工进度。
