slotted bucket meaning in English

齿槽式挑流鼻坎

Abstract : for high arch dams in valleys with the characteristics of high water head , large discharge and large power , the problems of energy dissipation and scour prevention are serious . based on scientific studies , new comprehensive measures are proposed , including dispersion of discharge to waken wallop of the current , and reinforcement of riverbed to enhance the erosion - resistance . the measures can be used to solve the problem of energy dissipation properly . a typical layout scheme has been proposed in which slotted bucket with diversion teeth , double deck with pores , and cushion pool are considered practice has proved that the scheme is reliable and the effect of energy dissipation is obvious
文摘:高拱坝泄洪消能的特点是坝高落差大，流量大，功率大，位于河谷狭窄地区，泄洪消能与防冲问题突出.经科学研究，采用“分散泄洪，削弱水流冲击力，加固河床，增强河道抗冲能力”的综合治理措施，较好地解决泄洪消能布置问题.提出了表孔大差动坎加分流齿、双层多孔、水流撞击、下设水垫塘联合消能的典型布置方案，经实践证明，方案可靠，消能效果好
