西江干流堤防护岸加固防渗技术应用

Application of Reinforcement and Seepage Prevention Technology for Embankment Protection in the Main Stream of Xijiang River

山堤防加固工程作为水利工程的重要组成部分之一,其防渗加固技术对保证工程的安全稳定具有重要意义。因此,如何利用好堤防加固施工技术,促进水利工程安全稳定运行,成为当前水利堤防工程的关键研究方向。文章以西江干流大堤除险工程为例,研究大型堤防的防渗护坡加固技术。根据堤防的防洪现状说明除险加固的必要性。随后详细探讨了堤防除险工程在贺江封开段护岸护坡采用的土工模袋混凝土和抛石护岸加固技术,德城大堤段石堤段采用摆喷防渗墙,土堤段采用垂直混凝土防渗墙,加固后进行工程安全稳定复核。在此基础上又提出了堤防安全监测方案,将有效增强堤防的防渗能力和整体安全稳定性,为其长期安全运行提供了坚实的保障,为水利工程堤防加固工程建设提供相关参考。

As one of the important components of water conservancy project,the reinforcement engineering of mountain embankments has significant importance in ensuring the safety and stability of the project through its anti-seepage and reinforcement technology.Therefore,how to make good use of levee strengthening construction technology to promote the safe and stable operation of water conservancy projects has become the key research direction of current water conservancy dike projects.This paper takes Xijiang main stream levee removal project as an example to study the seepage prevention and slope protection technology of large levees.According to the current situation of flood control of levees,the necessity of reinforcement is explained.Then,the paper discusses in detail the geofabriform concrete and riprap bank reinforcement technology used in Hejiang Fengkai section of the embankment protection,the pendulum spray cure-off wall used in the stone embankment section of Decheng embankment section,and the vertical concrete cure-off wall used in the earth embankment section.After reinforcement,the project safety and stability were checked.On this basis,the safety monitoring scheme of dike is put forward.It will effectively enhance the seepage prevention capacity and overall safety and stability of the dike,which will provide a solid guarantee for its long-term safe operation,and provide relevant reference for the construction of water conservancy engineering dike reinforcement projects.
