前言 碧口水电站在发电初期,由于泄洪建筑物尚未配套建成,迫于汛期在不利的调泄方式下过洪,尾水区域形成较大回流,以及其他等原因,使原厂房尾水渠右导墙末端至过木道之间的护岸工程经受不住水流冲淘遭致不同程度的破坏。进而威胁着右岸进厂公路及220千伏开关站的基础稳定。因此,必须进行补强处理,以确保电站正常发电。经广开思路,大胆设想,本着防护效果好,投资省,施工切实可行的原则,结合现实条件,在有关单位的协作下,终于找到一种既不影响发电经济效益,又能获得一定工程经济效果的水中投放预制混凝土四面体的护岸型式。通过一九八三年九月至一九八四年五月的间断性施工实践。
Preface Bikou hydropower station in the early stage of power generation, due to the flood discharge has not yet completed supporting structures, forced flood season under unfavorable flood control mode, the tail water area to form a greater return, and other reasons, The bank protection project between the end and the overpass can not withstand the current of water erosion to varying degrees. Which in turn threatens the stability of the foundation on the right bank into the highway and the 220 kV switchyard. Therefore, the reinforcement must be done to ensure that the plant is generating electricity normally. With the idea of wide openning and bold assumption, based on the principle of good protective effect, investment saving and construction practicable under realistic conditions, with the cooperation of relevant units, we have finally found a project that will not affect the economic benefits of power generation and obtain certain projects Economic effect of the water cast precast concrete tetrahedron bank protection type. Passed the intermittent construction practice from September 1983 to May 1984.
