Multifunctional nested sand discharging hole
The invention discloses a multifunctional nested sand discharging hole, and relates to the technical field of sand discharging. The multifunctional nested sand discharging hole comprises a reservoir, a high hole, a first low hole and a second low hole, wherein the high hole is formed in the water retaining end face of the reservoir, the first low hole and the second low hole are formed below the two sides of the high hole respectively, the high hole, the first low hole and the second low hole form delta-shaped sand discharging holes with the transverse interval of 35 mm and the longitudinal nesting of 7.5 mm, and the high hole, the first low hole and the second low hole are in communication to a sand discharging tunnel through pipelines respectively. According to the multifunctional nested sand discharging hole, the high hole and the low hole are nested in an elevation mode to form a mutual-assistance sand pulling mechanism, when normal work of the low hole is affected by sediment deposition, sediment deposition on the low hole can be reduced through a sand pulling funnel formed by sand discharging of the high hole based on the mutual-assistance sand pulling mechanism, the sediment pressure is reduced, the corresponding gate opening force is reduced, and the service life of a gate is prolonged.
本发明公开了一种多功能套叠排沙孔，它涉及排沙技术领域。包括水库、高孔、第一低孔、第二低孔，水库的挡水端面设置有高孔，高孔两侧下方分别设置有第一低孔、第二低孔，高孔、第一低孔、第二低孔形成横向间隔35mm，纵向嵌套7.5mm的品字形排沙孔，且高孔、第一低孔、第二低孔分别通过管道连通至排沙洞。本发明通过高孔与低孔之间高程嵌套形成一种互助拉沙机制，在泥沙淤积影响到低孔正常工作时，可以基于互助拉沙机制，利用高孔排沙形成的拉沙漏斗减少低孔上泥沙的淤积，减小泥沙压力，降低相应的启门力，提升闸门的使用寿命。
