摘要

充水式橡胶坝在充水后坝袋内顶部常有积气无法彻底排除,塌坝泄洪时坝袋底部常有尾水无法彻底排除。为解决这两项常见故障,在分析故障产生的原因及可能引发的一系列后果的基础上,发明了橡胶坝积气和尾水抽排系统,提出了抽排管路、抽排动力装置和控制系统的概念设计原理和方法。通过典型应用实例验证了该系统能有效排除积气和尾水故障及其引发的一系列问题,保障橡胶坝工程能够以最大高度蓄水,以最大过水断面泄洪,为橡胶坝工程精细化设计及改进传统设计方案提供了创新思路。

Abstract

In water-filled rubber dams, air often accumulates at the top of the dam bag following water filling, which is challenging to completely remove. Similarly, when the rubber dam collapses and discharges water, residual tailwater frequently remains at the bottom of the dam bag, resisting complete discharge. To tackle these common problems, a system for efficiently pumping and discharging accumulated air and tailwater in rubber dams has been developed. Based on an analysis of the underlying causes and potential consequences of these problems, this paper introduces conceptual design principles and methodologies for the pumping and discharging pipeline, power device, and control system. Through verification via typical application examples, it has been demonstrated that this system effectively mitigates faults caused by accumulated air and tailwater along with associated challenges, and also ensures the rubber dam impounds at maximum water level and discharges at maximum discharge section. This innovation offers valuable insights for the meticulous design of rubber dam projects and the enhancement of traditional design approaches.
