塘背圩堤防工程加固技术

Reinforcement Technology for Tangbei Embankment Engineering

塘背圩堤防现状破损严重,安全性较低,对区域防洪排涝影响较大,需要及时采取防渗加固治理措施。结合工程实际情况,对堤防工程断面进行整治,经分析后堤防整体稳定性满足要求,但仍存在渗漏风险。选取常用的防渗加固方案进行比选分析,采用冲抓套井粘土心墙方案施工简便、造价低,优势明显,作为推荐方案,可为类似工程提供参考。

The current situation of the Tangbei embankment is severely damaged,with low safety,and a significant impact on regional flood control and drainage.It is necessary to take timely anti-seepage and reinforcement measures.Based on the actual situation of the project,the cross-section of the embankment project was renovated.After analysis,the overall stability of the embankment meets the requirements,but there is still a risk of leakage.Commonly used anti-seepage reinforcement schemes for comparison and analysis is selected.The use of the flushing and grabbing well clay core wall scheme is easy to construct,low cost,and has obvious advantages.As a recommended scheme,it can provide reference for similar projects.
