Flexible box type grid ecological bridge pier bottom protection structure
The invention discloses a flexible box type grid ecological bridge pier bottom protection structure which comprises a bridge pier, a bearing platform arranged below the bridge pier and a plurality of pile foundations used for supporting the bearing platform, an annular water-permeable grid box corresponding to the bridge pier in shape is arranged on the outer side of the bridge pier, and the inner side size of the water-permeable grid box corresponds to the outer side size of the bridge pier. The permeable grating box is arranged on the bearing platform, and the top surface of the permeable grating box is flush with a corresponding river bed; stone is filled in the water-permeable grating box, a plurality of fish nest bricks are fixedly embedded in grids formed by the top face and the outer side face of the water-permeable grating box at intervals, the outer surfaces of all the fish nest bricks are lower than the corresponding face of the water-permeable grating box, and therefore a plurality of pits are formed in the top face and the side face of the water-permeable grating box. The bottom protection structure can effectively slow down the water flow velocity near the bridge pier, weaken scouring, avoid bridge body instability caused by the fact that the bottom of the bridge pier is scoured by descending water flow and a vortex system, provide a spawning site and a predator site for benthic organisms and fishes, and make up the negative influence of bridge pier construction on the ecological environment of a water system.
本发明公开了一种柔性箱式格栅生态桥墩护底结构，包括桥墩、设于桥墩下方的承台以及用于支撑承台的若干桩基，在桥墩外侧设有与桥墩形状对应的环状透水格栅箱，且透水格栅箱内侧尺寸和桥墩外侧尺寸对应，透水格栅箱设置在承台上且透水格栅箱顶面与对应河流河床平齐；透水格栅箱内填充有石料，在透水格栅箱顶面和外侧面格栅形成的方格内间隔嵌设固定有若干鱼巢砖，所有鱼巢砖外表面低于透水格栅箱对应面，从而在透水格栅箱顶面和侧面形成若干凹坑。该护底结构能有效减缓桥墩附近的水流流速，减弱冲刷，避免桥墩被下降水流及涡旋体系冲刷底部导致的桥体失稳，同时还能底栖生物、鱼类提供产卵场与捕食场，弥补桥墩建设对水系生态环境造成的负面影响。
