Pier water flow resistance reducing device
The invention relates to the technical field of pier resistance reducing equipment, in particular to a pier water flow resistance reducing device. The device is characterized in that: a pre-embedded assembly is arranged on the back flow side of a pier, and a fixing plate group is used for fixing rectification cloth and is rotationally connected with the pre-embedded assembly through a supporting rod; the embedded assembly comprises a plurality of arc groove clamping blocks arranged in the vertical direction and an arc groove supporting block arranged at the bottommost portion, and the arc groove supporting block is used for supporting the supporting rod; and the fixing plate group comprises a first fixing plate and a second fixing plate, the first fixing plate and the second fixing plate are mutually pressed, one end of the fixing plate set is connected with the supporting rod, and the rectifying cloth is pressed and fixed by the other end of the fixing plate set through the first fixing plate and the second fixing plate. The rectification cloth is arranged on the back of water flow of the bridge pier, formation of water flow vortex on the back of the bridge pier can be disturbed, and the negative pressure of the back of the bridge pier is adjusted; and the flexible rectification cloth is matched with the fixing plate group to swing at the arc-shaped opening of the arc groove clamping blocks and adapt to the flow direction of the water flow, and therefore the flowing water resistance borne by the bridge pier is reduced.
本发明涉及桥墩减阻设备技术领域，尤其涉及一种桥墩水流阻力减小装置，其中，预埋组件设置在桥墩背流侧，固定板组用于固定整流布，并通过支撑杆与预埋组件转动连接；预埋组件包括沿竖直方向设置的多个弧槽夹块和设置在最下方的弧槽支撑块，弧槽支撑块用于支撑支撑杆；固定板组包括第一固定板和第二固定板，第一固定板和第二固定板相互压紧，且固定板组的一端与支撑杆相连，另一端通过第一固定板和第二固定板将整流布压紧固定。通过在桥墩的水流背向设置整流布，能够干扰桥墩背向水流旋涡的形成，调节桥墩背部负压，柔性的整流布配合固定板组能够在弧槽夹块的弧形开口处摆动并适应水流的流向，从而降低桥墩受到的流水阻力。
