Circular combined cofferdam of seasonal water area bridge rock-socketed foundation and construction method
The invention discloses a circular combined cofferdam for seasonal water area bridge rock-socketed foundation and a construction method. The circular combined cofferdam comprises a circular secant pile cofferdam, a top beam at the tops of secant piles and a circular double-wall steel cofferdam body arranged on the top beam. The circular secant pile cofferdam is formed by arranging secant piles A and secant piles B in a staggered mode. The top beam is of a reinforced concrete structure, the secant piles A and the secant piles B are connected into a whole through anchor bars reserved at the topsof the secant piles, the double-wall steel cofferdam is of a traditional structure in the prior art, the bottom of the double-wall steel cofferdam is hollow and connected with the top beam, and shearreinforcements are arranged on the connecting section and used for pouring bin clamping concrete to stop water. The secant piles A are plain concrete piles with anchor bars at the tops or reinforcedconcrete piles with rectangular reinforcement cages, and the secant piles B are reinforced concrete piles with circular reinforcement cages or reinforced concrete piles with rectangular reinforcementcages. The method is short in construction period, low in construction risk, low in resource consumption and low in engineering cost.
本发明公开了一种用于季节性水域桥梁嵌岩基础施工的圆形组合围堰及施工方法，包括圆形咬合桩围堰、咬合桩顶部的冠梁和设置于冠梁上的圆形双壁钢围堰。所述圆形咬合桩围堰由咬合桩A和咬合桩B交错排列组成，所述冠梁为钢筋混凝土结构，通过咬合桩顶部预留的锚筋将咬合桩A和咬合桩B连成整体，所述双壁钢围堰为现有技术传统结构，底部中空并与冠梁连接，连接段设置剪力钢筋并浇筑夹仓混凝土止水。所述咬合桩A为顶部设锚筋的素混凝土桩或设置矩形钢筋笼的钢筋混凝土桩，所述咬合桩B为设置圆形钢筋笼的钢筋混凝土桩或设置矩形钢筋笼的钢筋混凝土桩。本发明施工周期短，施工风险降低，资源消耗少，工程造价低。
