小型水库除险加固工程施工技术研究

Research on Construction Technology of Small Reservoir Reinforcement Engineering

水库是防洪的重要屏障,在水利工程建设与运行中发挥着重要的作用。为增强小型水库防洪抗汛的能力,应进行除险加固,增强其牢固性与稳定性,有效降低小型水库运行中的安全隐患。文章简要论述了小型水库病险的主要类型及其危害,重点从帷幕灌浆、土石坝坝体灌浆、坝体填筑、混凝土浇筑、综合防渗、库岸失稳防治6大方面分析了小型水库除险加固工程的常用施工技术,旨在为小型水库除险加固工作的开展提供思路与方法。

Reservoir is an important barrier for flood control and plays an important role in the construction and operation of water conservancy projects.In order to enhance the flood control and anti flood ability of small reservoirs,danger removal and reinforcement should be carried out to enhance their firmness and stability,and effectively reduce the potential safety hazards in the operation of small reservoirs.This paper briefly discusses the main types and hazards of small reservoirs,and mainly analyzes the common construction technologies of small reservoirs'risk elimination and reinforcement engineering from six aspects:curtain grouting,earth rock dam dam grouting,dam filling,concrete pouring,comprehensive seepage prevention,and reservoir bank instability prevention,so as to provide ideas and methods for the development of small reservoirs'risk elimination and reinforcement work.
