若干年来,一种采用连续钢质承压条兼作刚性止水的新的人字门型被引进并首先应用于葛洲坝船闸。经过运行,在高水头、多泥沙和岩基的条件下, 已显示出一系列优越性,例如闸首门墩承受人字门横梁传来的不是集中力而是分布力,减小了门墩和底板的弯矩;在高水头多泥沙条件下,刚性止水比橡胶柔性止水耐用,并减少了大量的检修时间。但是采用这种门型也有其不利的一面:其一是顶、底枢和承压条的制作安装要求很
For a number of years, a new type of gable that uses continuous steel pressure strips as rigid water stop is introduced and first applied to the Gezhouba Dam lock. After operation, a series of superiorities have been shown under high head, sediment and rock foundation conditions. For example, the pier at the gate of a gate does not concentrate but distributes force to bear the beam, Bottom plate bending moment; Under the conditions of high water head and sediment, the rigid water stop is more durable than the flexible rubber water stop, and reduces a lot of maintenance time. However, the use of this type of door also has its downside: one is the top, bottom pivot and the pressure of the production of the installation requirements are
