Shackle and retainer combined sleeve type pier scour prevention device and method
The invention discloses a shackle and retainer combined sleeve type anti-scouring device for a pier. The anti-scouring device comprises a supporting sleeve, an upper protective part, a lower protective part and a protective surrounding ring. The inner circumferential edges of the upper protection piece and the lower protection piece are fixed to the top end and the bottom end of the supporting sleeve respectively. The protective surrounding ring is fixed to the outer circumferential edge of the upper protective piece. In the working process, the supporting sleeve, the upper protection piece and the lower protection piece are arranged on the outer side of the bottom of the pier in a sleeving mode. The upper protection part is used for blocking downward jet flow formed when water flow impacts on the pier, and the protection surrounding ring is used for blocking the jet flow impacted on the upper protection part from flowing to the outer end. The protective surrounding ring is arranged at the edge of the upper protective part and used for blocking water flow flowing along the surface of the upper protective ring, and the situation that jet flow above the upper protective part moves out of the range of the upper protective ring, is affected by water flow below and continues to move downwards, and consequently impact damage is caused to gravel in a riverbed below is avoided.
本发明公开了一种钩环护圈组合套筒型桥墩防冲刷装置，其包括支撑套筒、上防护件、下防护件和防护围环。上防护件和下防护件均呈环形，且内圆周边缘分别固定在支撑套筒的顶端和底端。防护围环固定在上防护件的外圆周边缘。工作过程中，支撑套筒、上防护件和下防护件套置在桥墩底部的外侧；上防护件用于阻挡水流冲击在桥墩上形成的向下的射流，防护围环用于阻挡冲击在上防护件上的射流向外端流动。本发明通过在上防护件的边缘处设置防护围环，用于阻挡沿着上护圈表面进行流动的水流，避免上防护件上方的射流运动至上护圈范围以外时，受下方的水流影响，继续下行，从而对下方河床中的沙石产生冲击损伤。
