Frame reinforcing system and method for channel underneath passing high-speed rail pier pile foundation
The invention discloses a frame reinforcing system and method for a channel underneath passing high-speed rail pier pile foundation. The method comprises the steps of reinforcing a channel underneathpassing section base, reinforcing a channel underneath passing section support, reinforcing the pier pile foundation, excavating a foundation pit under a bridge, paving and reinforcing a riverbed bottom and providing anti-collision facilities. The frame reinforcing system is designed from the three aspects of lateral displacement prevention, scouring prevention and collision prevention of the foundation, the displacement of the pier top of a pier is controlled within the deformation control standard in the construction period, the bridge structure and high-speed rail operation safety are not affected by channel excavation, and the pier is not impacted by ships in the channel operation process. The frame reinforcing system and method have the advantages that the reinforcing depth is large,the reinforcing effect is reliable, the water stopping performance is good, recycling is convenient, and the influence on the high-speed rail pier pile foundation and the environment is reduced to themaximum extent.
本发明公开了一种航道下穿高铁桥墩桩基的框架加固体系和加固方法，包括航道下穿段基底加固、航道下穿段支撑加固、桥墩桩基加固、桥下基坑开挖、河床底铺砌和加固和防撞设施。本发明从基础防侧向位移、防冲刷和防撞三方面进行设计，形成一种框架加固体系，确保桥墩墩顶位移在施工期间控制在变形控制标准内，不因航道开挖而影响桥梁结构及高铁运营安全，并在航道运营过程中确保桥墩不受船舶撞击。本发明具有加固深度大、加固效果可靠、止水性好、便于回收利用并最大程度减少对高铁桥墩桩基和环境的影响等优点。
