Flood protection method for high-fall water level construction trestle
The invention relates to a high-fall water level construction trestle flood protection method which comprises the following steps: during construction of a construction trestle, after steel pipe piles are sequentially driven into soil at the bottom of a river, steel bars are driven into a soil layer, and the piles are grouted and concrete is poured; a circular steel pipe connecting system is adopted as a parallel connection to connect two adjacent steel pipe piles; three pull lugs are uniformly welded on the side wall of the upper part of the steel pipe pile at the normal water level elevation on the upstream face from top to bottom, and then an upper structure of the construction trestle is mounted; anchor bridge hole guiding construction is conducted, and after hole guiding is completed, an anchor bridge body is placed at the corresponding position, and then underwater concrete is poured; flood control inhaul cables are installed between the corresponding pull lugs and the corresponding anchorage devices, and one anchorage device is connected with the three flood control inhaul cables on the same steel pipe pile; and when the flood period comes, the flood control pull net is tensioned, and the set height of the top of the flood control pull net is flush with the flood level elevation. The stability of the high-fall water level construction trestle under the flood effect can be effectively improved, and the construction trestle is prevented from being washed away under the flood effect.
本发明是一种高落差水位施工栈桥洪水防护方法，包括以下步骤：在施工栈桥施工时，钢管桩依次打入到河流底部泥土中后，将钢筋打入土层并灌桩浇筑混凝土；采用圆钢管连接系作为平联对相邻两个钢管桩进行连接；在迎水面的钢管桩位于常水位标高的上部侧壁由上到下均匀焊接三个拉耳，然后安装施工栈桥上部结构；进行锚啶引孔施工，引孔完成后将锚啶体下放置对应位置后浇筑水下混凝土；在对应的拉耳和锚具之间安装防洪拉索，一个锚具与同一根钢管桩上的三个防洪拉索连接；待洪水期来临时张拉防洪拉网，防洪拉网顶部设置高度与洪水位标高平齐。本发明可有效提高洪水作用下高落差水位施工栈桥的稳定性，防止洪水作用下施工栈桥被冲垮。
