Fabricated pier anti-scouring device and method
The invention discloses an anti-scour device and method for a fabricated pier. The anti-scour device for the fabricated pier comprises a supporting cylinder, an upper protection part and a lower protection part. The inner circumferential edge of the upper protection piece is fixed to the top end of the supporting cylinder; the lower protection piece is divided into a semicircular truncated cone part and a pointed cone part; the outer surface side of the semicircular truncated cone part is in a big-end-down partial circular truncated cone surface shape; the sectional area of the pointed cone part is gradually reduced in the direction away from the semicircular truncated cone part; in the working process, the supporting cylinder, 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 semi-circular truncated cone part is opposite to the water flow direction; the upper protection piece blocks downward jet flow formed by water flow impacting on the pier; the lower protection piece provides protection for the joint of the pier and riverbed sediment; by arranging the upper protection part and the lower protection part, downward jet flow generated when water flow impacts on the pier is prevented from directly impacting the joint of the pier and a riverbed. Impact damage of jet flow to sand and stones in a riverbed is avoided, so that the upright stability of the pier is not influenced.
本发明公开了一种装配式桥墩防冲刷装置及方法，该桥墩防冲刷装置包括支撑筒、上防护件和下防护件；上防护件呈环形，且内圆周边缘分别固定在支撑筒的顶端；下防护件分为半圆台部和尖锥部；半圆台部的外面侧呈上小下大的部分圆台面状；尖锥部在远离半圆台部的方向上截面积逐渐缩小；工作过程中，支撑筒、上防护件和下防护件套置在桥墩底部的外侧；半圆台部与水流方向正对；上防护件阻挡水流冲击在桥墩上形成的向下的射流；下防护件对桥墩与河床泥沙的连接处提供防护；本发明通过设置上防护件和下防护件，用于阻挡水流冲击在桥墩上产生的向下的射流直接冲击在桥墩与河床的连接处。避免射流对河床中的沙石产生冲击损伤，从而影响桥墩直立的稳定性。
