River channel diversion construction method for bridge construction
The invention discloses a bridge construction riverway diversion construction method, which relates to the technical field of bridge construction, and adopts the following steps: construction preparation: carrying out on-site check and construction investigation, carrying out survey lofting according to a drawing, a working surface and the like, and determining riverway diversion and island building filling position areas; a river channel with the bottom width of about 8 m is excavated at the position 15-20 m away from the back of the bridge abutment, and the excavation gradient of the river channel is controlled according to 1: 0.75; when the shortcut passes through the river changing channel, a span steel bridge is arranged; building an island and filling a river: filling a temporary shortcut entering the construction site from the river changing river channel with building slag, starting island building and soil filling after completion, considering the lower part of an island building and soil filling material according to shale, and filling the upper part of the island building and soil filling material with continuous gravel with the thickness of 30cm; a system project guided by a river is completed in an extremely limited site, normal circulation of water flow needs to be guaranteed after an island is built, hillsides are avoided, and meanwhile a passing bridge is constructed on a transformed river.
本发明公开了一种桥梁施工河道改道施工方法，涉及桥梁施工技术领域，采用以下步骤：施工准备：进行现场核对和施工调查，根据图纸及工作面等进行测量放样、确定出改河和筑岛填筑位置区域；河道改道：在距桥台台后15m‑20m位置开挖一条底宽约8m的河道，河道开挖坡度按1：0.75控制；桥梁施工进入便道施工：便道经过改河河道时设置跨径钢桥一座；筑岛填河：从改河河道处进入施工现场的临时便道采用建渣填筑，完成后开始筑岛填土，筑岛填土材料下部按页岩考虑，上部采用30cm厚连砂石填筑；在极其有限的场地内完成了一个河流导引的一个系统工程，筑岛后需保证水流正常流通，避让山坡，同时又在改造河流上施工了一个通行用桥。
