Hydropower station gate underwater leaking stoppage method
According to the underwater leaking stoppage method for the hydropower station gate, leaking stoppage particles are screened, and when the leaking stoppage particles are filled, the size of the leaking stoppage particles loaded to the bottommost layer is evaluated according to the field water leakage condition. The leaking stoppage particles generally move obliquely downwards along with water flow in flowing water, and the higher the water flow speed is, the higher the movement speed is. When the leaking stoppage particles are put on the waterside of the gate, the leaking stoppage particles sink to the water bottom slowly due to the fact that the volume weight of the leaking stoppage particles is slightly larger than that of water, and when the leaking stoppage particles sink to the position near a water leakage point of the gate, the leaking stoppage particles are absorbed to the water leakage point along water flow under the action of surrounding high pressure due to the fact that pressure difference exists inside and outside the water leakage point and the pressure intensity is reduced in the water flow direction. The propeller is used for generating high-speed water flow, under the action of high pressure around a leakage point, the leaking stoppage particles are absorbed to the leakage point along the water flow and block a leakage gap, the leaking stoppage particles can enter the deep position of the gap, and the leaking stoppage quality is greatly improved.
一种水电站闸门水下堵漏方法，将堵漏颗粒进行筛选，装填堵漏颗粒时根据现场漏水情况进行评估装载到最底层的堵漏颗粒的大小。堵漏颗粒在动水中一般随水流斜向下运动，水流速度越快，运动速度也越快。当在闸门临水面投放堵漏颗粒时，由于堵漏颗粒容重比水稍大，它就慢慢向水底沉落，沉到闸门漏水点附近时，由于漏水点内外存在压差，压强沿水流方向降低，在周围高压的作用下，堵漏颗粒顺水流被吸收到漏水点，堵到漏水的缝隙上。本发明利用推进器产生高速水流，并在漏点周围高压的作用的，堵漏颗粒顺水流被吸收到漏水点，堵到漏水的缝隙上，堵漏颗粒能够进入缝隙深处，堵漏质量大大提高。
