Trestle-free overwater bridge pile foundation and bearing platform construction method
The invention discloses a trestle-free overwater bridge pile foundation and bearing platform construction method. The construction method adopts a cofferdam and floating bridge combined mode to realize trestle-free construction operation, the cofferdam encloses a construction area in water, and pile foundation and bearing platform construction is carried out in the construction area; the cofferdamis of a rhombus structure, so that water flow impact force borne by the whole cofferdam is smaller, a cofferdam and floating bridge combined mode is adopted to replace a traditional cofferdam and trestle combined mode for construction, and compared with a trestle, the floating bridge is convenient to assemble and disassemble, lower in manufacturing cost and capable of being repeatedly used.
本发明公开了一种无栈桥的水上桥梁桩基及承台施工方法，该施工方法采用围堰和浮桥相结合的方式实现无栈桥的施工作业，所述围堰在水中圈出施工区域，在施工区域的内部进行桩基和承台的施工；本发明中围堰采用菱形结构的方式，使得围堰整体受到的水流冲击力更小，采用围堰加浮桥的方式代替传统的围堰加栈桥的方式进行施工，浮桥相对于栈桥来说，不仅便于进行安装和拆卸，而且造价更低，也能够进行重复的使用。
