前言 随着水电建设的发展,水电站闸门逐步向着大孔口高水头方向迈进。为解决高水头,特别是百米以上高水头弧门的水封问题,国外巳普遍采用偏心铰弧门压紧式封水方式。我国在建的龙羊峡底孔5×7—120米工作弧门及东江二级放空洞6.4×7.5—100米工作弧门也采用了偏心铰弧门型式,使我国在水电站金属结构领域跨入了世界先进水平的行列。 本文试根据我国制造安装的具体情况,对偏心铰弧门设计中的几个问题提出某些看法以供讨论参考。
Preface With the development of hydropower construction, hydropower gate gradually toward the direction of a large head of high aperture. In order to solve the problem of water seal of high water head, especially high water head of over one hundred meters, foreign eccentric arc hinge door has been used to compress water seal. China’s under construction Longyangxia bottom hole 5 × 7-120 m working arc and Dongjiang secondary venting hole 6.4 × 7.5-100 m working arc also used eccentric hinge arch type so that our country in the field of metal structures of hydropower Into the ranks of the world’s advanced level. Based on the specific conditions of manufacture and installation in our country, this paper puts forward some views on some issues in the design of eccentric hinge arch doors for discussion and reference.
