Floating arch cofferdam reinforcing construction method
The invention discloses a floating arch cofferdam reinforcing construction method, and belongs to the technical field of cofferdams. The floating arch cofferdam reinforcing construction method comprises the following steps of pre-burying buffer pipes: burying a plurality of buffer pipes in a river channel in an arc shape, and enabling the tops of the buffer pipes to be above the water surface; erecting an arch cofferdam: erecting the arch cofferdam on the tops of the buffer pipes, and deeply inserting connecting pipes at the bottom of the arch cofferdam into the buffer pipes; erecting a buffer layer: annularly erecting the buffer layer on the outer side of the arch cofferdam; and erecting a flow guide slope: annularly erecting the flow guide slope on the outer side of the buffer layer, wherein the side, close to a dam, of the flow guide slope is connected with the dam. According to the floating arch cofferdam reinforcing construction method, the impact force of water is relieved through multi-layer buffer, and the impact force of water is reduced through the flow guide structure on the outermost layer, so that the stability of the floating arch cofferdam is guaranteed, and the effect of reinforcing the floating arch cofferdam is achieved.
本发明公开了围堰技术领域的一种浮式拱围堰加固施工方法，该浮式拱围堰加固施工方法包括如下步骤：预埋缓冲管：将多个缓冲管呈弧形埋设在河道中，缓冲管的顶部在水面以上；架设拱围堰：将拱围堰架设在缓冲管的顶部，拱围堰底部的连接管深插在缓冲管的内部；缓冲层架设：将缓冲层呈环形架设在拱围堰的外侧；导流斜坡：导流斜坡呈环形架设在缓冲层的外侧，导流斜坡临近堤坝的一侧与堤坝连接在一起，本发明通过多层缓冲减缓水的冲击力，并且通过最外层的导流结构减少水的冲击力，以此保障浮式拱围堰的稳定性，起到加固浮式拱围堰的作用。
