犁湾河工程河道导流与防渗墙施工要点

Key Points of River Diversion and Cut-off Wall Construction of Liwan River Project

在河道治理工程中,导流和防渗墙是两个重要的工程项目,必须保证其施工的质量。目前,中国的防渗墙技术日趋成熟,在水利、电力等各个工程领域里广泛应用,尤其在河道治理工程中发挥着极其重要的作用。特别是最近几年,新技术、新工艺、新材料不断涌现,更加完善了混凝土防渗墙技术,显著提升了整体工程的质量。文章主要介绍了犁湾河工程河道导流与防渗墙施工要点,该河段以下游汇入大塘水河口处(桩号K0+000)为起点,一直到侯山村附近(桩号K3+862)结束,治理工程改善河道行洪状况,稳定了岸坡,为后续工程积累了经验.

In the river regulation project,diversion and cut-off wall are two important engineering projects,and the construction quality must be guaranteed.At present,the technology of cut-off wall in China is becoming more and more mature,which is widely used in various engineering fields such as water conservancy and electric power,especially in river regulation engineering.Especially in recent years,new technologies,new processes and new materials have been emerging,which has further improved the concrete cut-off wall technology and significantly improved the quality of the overall project.This paper mainly studies the key points of river diversion and cut-off wall construction of Liwan River project.The starting point of the river section is at the downstream confluence into Datangshui estuary(chainage K0 + 000) and ends near Houshan Village(chainage K3 + 862).The treatment works improve the flood discharge condition of the river and stabilize the bank slope,which has accumulated experience for subsequent works.
