东平湖八里湾闸改建工程设计综述

Introduction to Re-construction Design of Baliwan Lockgate in Dongpinghu Lake

摘要:

通过对老湖调洪计算,合理确定东平湖八里湾闸南排设计起始排水位和相应设计泄洪流量;根据改建工程需要,满足南排、新老两湖共用、灌溉和排涝等不同的功能需要;采用桩基开敞式,减少了闸室沉陷量,抗滑稳定性好,运行更为安全可靠;闸室布置了1个低孔和6个高孔,高孔采用折线型底板,消能工采用二级平底消力坎式消能,节省工程投资;首次采用往复式高压喷射灌浆新技术解决了闸室垂直防渗和两岸的绕渗;胸墙的分块设计减小了结构尺寸和配筋数量;首次把钉板型铜塑复合材料应用在平面钢闸门滑块设计中,解决了水电工程平面钢闸门滑动支承所要求的低摩擦系数、抗磨耗和使用寿命长的问题。

Abstract:

Through measurement for regulating flood ability of old and new lakes,initial discharge level and related flood discharge amount to south part of Baliwan Lockgate are determined reasonably.It can meet the demand of many functions,such as flood discharge to south part,old and new lakes sharing,irrigating and draining flooded fields.By using opening fundation,subsidence amount of lockgate can be reduced with stable resistance of sliding and run safetly.1 low hole and 6 high holes are arranged in lockgate,and ...
