平原灌区水闸的闸下防冲是多年来困扰灌区工程技术人员和水利科研工作者的一项技术难题。一直未能在既有效防冲 ,又不过分提高消能设计标准的双重约束条件下有所进展。其中海漫的进一步消能和调整流速分布的功能没有充分发挥是原因之一 ,海漫柔性增糙技术在不改变水闸工程原有其它消能设施的情况下 ,只在海漫段布设柔性增糙体 (废旧轮胎 ) ,就可以很好地实现闸下防冲的目的 ,而且造价低廉。下面系统地介绍了这一新技术的原理、方法、特点及效果 The flood control gate sluice under the flood plain is a technical problem that has plagued the irrigation engineers and water conservancy researchers over the years. It has not been able to make any progress under the dual constraints of not only making effective anti-rush measures but also not excessively improving the energy-saving design standards. Among them, the function of further energy dissipation and adjustment of velocity distribution in the sea is not fully exerted. One of the reasons is that, without changing other existing energy dissipation facilities in the sluice project, Rough (waste tires), you can well under the gate to achieve the purpose of anti-red, and low cost. The following systematically introduces the principle of this new technology, methods, features and effects
