柘林水利枢纽第一溢洪道位于主坝右岸,为开敝式三级底流消能河岸溢洪道。总宽42米,分三孔,每孔净宽12米,设计泄流量(P=0.1％)3310秒立米,陡槽段最大流速24米/秒。本工程于1973年建成,当年6月开闸放水。1977年江西省水电设计院在“柘林水利枢纽补强加固及收尾工程设计报告”中提出:(1)原设计没有及时发现各级消力池特别是一级消力池梳齿的空蚀问题,现应予处理;(2)陡槽段有几处止水缝渗水;(3)陡槽段,特别是陡槽中园
The first spillway of Zhelin Water Control Project is located on the right bank of the main dam, which is an open type three-stage underflow energy-dissipating bank spillway. The total width of 42 meters, divided into three holes, each hole net width of 12 meters, the design discharge (P = 0.1%) 3310 seconds legislation, chute segment maximum flow rate of 24 m / s. The project was completed in 1973, when the floodgate in June. In 1977, Jiangxi Provincial Hydropower Design Institute put forward in “Design Report of Reinforcement and Finishing Project of Gao Lin Hydraulic Complex”: (1) The original design did not find cavitation erosion The problem should be dealt with now; (2) there are several water-stop cracks in the chute section; (3) the chute section, especially the chute in the garden
