Bridge main pier bearing platform foundation pit supporting structure and construction method thereof
The invention relates to the field of building construction, and particularly discloses a bridge main pier bearing platform foundation pit supporting structure and a construction method thereof. The foundation pit supporting structure comprises a plurality of mutually-connected steel sheet piles, the mutually-connected steel sheet piles form a foundation pit supporting wall, and each steel sheet pile comprises a steel sheet pile body, a first sealing connection assembly arranged on one side of the steel sheet pile body and a second sealing connection assembly arranged on the other side of the steel sheet pile body. During forming of the foundation pit supporting wall, every two adjacent steel sheet pile bodies are buckled in the reverse direction, the first sealing connection assembly of one steel sheet pile body and the second sealing connection assembly of the adjacent steel sheet pile body are engaged with each other, the connection sealing performance is guaranteed, and meanwhile the connection strength is also guaranteed. In addition, at the corner of the bridge main pier bearing platform foundation pit, the two perpendicular foundation pit supporting walls are connected in a sealed mode through a corner connecting plate, the corner connecting plate guarantees the sealing performance and strength of connection of the steel sheet piles at the ends of the two foundation pit supporting walls, and the anti-seepage effect is good.
本申请涉及建筑施工领域，具体公开了一种桥梁主墩承台基坑支护结构及其施工方法。其中，基坑支护结构包括多个相互衔接的钢板桩，相互衔接的钢板桩形成基坑支护墙，所述钢板桩包括钢板桩主体，设置在钢板桩主体一侧的第一密封衔接组件以及设置在所述钢板桩主体另一侧的第二密封衔接组件，基坑支护墙成型时，相邻的两个钢板桩主体反向扣合，钢板桩主体的第一密封衔接组件与相邻钢板桩主体的第二密封衔接组件相互咬合，保证了衔接的密封性，同时也保证了衔接的强度。另外，桥梁主墩承台基坑拐角处，两个垂直的基坑支护墙通过拐角衔接板密封衔接，拐角衔接板保证了两个基坑支护墙端部钢板桩连接的密封性和强度，抗渗效果好。
