南水北调中线一期工程总干渠漳古段边坡塌方加固处理方法

Consolidation Method to Treat the Side Slope Landside in the Zhang-gu Canal Reach of the General Main Canal of the South-to-North Water Diversion Middle Line Project(First Phase)

南水北调中线一期总干渠漳古段工程为大型断面I等渠道工程,渠底宽22 m,设计流量220 m3/s。文中介绍了渠道桩号146+700-147+500段左岸边坡发生塌方情况,针对不同马道、坡面而采取了不同的加固处理方法,重点阐述了抗滑桩、连系梁、框格梁等主要加固工序的质量控制要点,并提出了今后对坡面易塌方段进行加固处理时应注意的事项。

The Zhang-Gu canal reach project of the general main canal of the South-to-North Water Diversion Middle Line Project is a large-sized rank I canal project.Its width of conal bottom is 22 m,and the design discharge is220 m^3/s.The situation of canal side slope landside in the left bank of canal reach,which position is located from chainage 146＋700 to chainage 147＋500,is introduced in this paper.For different berms and slope surfaces,the different consolidation and treatment methods have been used in this project.The paper emphatically narrates a set of quality control key points of consolidation measures such as antiskid pile,connecting beam and cellular beam,and puts forward some matters needing attention for consolidating and treating the landside accident of slope surface in future.
