Soil foundation spillway structure with bottom expansion type anchoring column piers
The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a soil base spillway structure with bottom expansion type anchoring column piers. Bottom expansion type anchoring column piers are arranged in soil foundations below a discharge chute upstream part and a discharge chute downstream part, and the bottom expansion type anchoring column piers are connected with the discharge chute upstream part, the discharge chute downstream part and a tooth wall through an anti-vibration connecting system; when the spillway discharges flood, the discharge chute upstream part and the discharge chute downstream part vibrate up and down or slide along the water flow direction under the action of pulsating water pressure of water flow, drag force of the water flow and lifting pressure of a plate bottom, the discharge chute upstream part and the discharge chute downstream part are subjected to anchoring force transmitted by the bottom expansion type anchoring column piers, so that the discharge chute upstream part and the discharge chute downstream part are difficult to vibrate or slide; and meanwhile, the vertical settlement of the upstream part and the downstream part of the discharge chute is reduced under the vertical supporting action of the bottom expansion type anchoring column piers, the problems of up-down vibration, downstream sliding and vertical settlement of the bottom plate of the soil foundation spillway can be solved by using the structure, and meanwhile, the engineering investment is reduced.
本发明属于水利水电工程技术领域，具体涉及一种具有底扩式锚固柱墩的土基溢洪道结构。本发明在泄槽上游部、泄槽下游部下方的土质地基中布置底扩式锚固柱墩，通过抗振连接系统将底扩式锚固柱墩与泄槽上游部、泄槽下游部、齿墙连接起来；当溢洪道泄洪时，泄槽上游部、泄槽下游部在水流的脉动水压力、水流的拖曳力和板底扬压力作用下，上下振动或顺水流向滑动时，会受到底扩式锚固柱墩传来的锚固力，使泄槽上游部、泄槽下游部难以振动或滑动，同时在底扩式锚固柱墩的竖向支撑作用下降低了泄槽上游部、泄槽下游部的竖向沉降，使用该结构能解决土基溢洪道底板的上下振动、顺水流向滑动及竖向沉降问题，同时降低工程投资。
