摘要
在河床边滩较宽、水位落差大的情况下,常规的固定式浮码头其前沿线伸缩较小,高水位时影响通航安全,其使用和推广受到了一定制约。拆装式浮码头作为一种新颖的浮码头型式,可依据水位的变化,通过增加或减少活动钢引桥的数量,调节码头前沿位置,可有效地解决码头布置与通航要求之间的矛盾。结合工程实例,系统地介绍了拆装式浮码头设计方案及使用效果,对今后类似工程的设计具有一定的指导意义。
For the condition of wider river beach and larger water level drop, the regular fixed floating dock will influence navigation safety in the case of high water level for its smaller frontal extending space, which limits the application of regular fixed floating dock. The assembly -type floating dock is a new one and its application can regulate the frontal location of dock through increasing or decreasing the movable steel bridge approach according to water level variation and effectively solve the contradiction between dock layout and navigation. With the combination of practical case, the design scheme and practical operation effect of assembly - type floating dock are systematically presented, which has some guidance significance for similar projects in future.
