Flexible grid surface type grid pier guardrail structure
The invention discloses a flexible grid surface type grating bridge pier guardrail 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, a plurality of supporting columns are evenly distributed on a riverbed corresponding to the periphery of the bridge pier, and all the supporting columns are vertically arranged. The supporting columns extend downwards, the lower ends of the supporting columns are at least flush with the upper surface of the bearing platform, a flexible steel wire net is arranged between every two adjacent supporting columns, so that an annular guardrail is formed outside the pier, and a plurality of energy dissipation blocks are stacked on the corresponding bearing platform between the pier and the guardrail. The guardrail structure can effectively reduce the flow rate of water flow around the pier, reduce or even avoid impact of solids carried in the water flow on the pier, and improve the protection effect of the pier.
本发明公开了一种柔性网格面式格栅桥墩护栏结构，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，在桥墩周围对应的河床上均匀分布有若干支撑柱，所有支撑柱竖直设置，支撑柱向下延伸且支撑柱下端至少与承台上表面平齐，在相邻两支撑柱之间设有柔性钢丝网，从而在桥墩外构成环形的护栏，并在桥墩和护栏之间对应的承台上堆放有若干消能块。该护栏结构能有效减缓桥墩周围水流流速，减小甚至避免水流中携带的固体物对桥墩造成冲击，提高桥墩的防护效果。
