摘要
介绍了长江重要堤防隐蔽工程建设的规模及堤防地基的地质条件和险情 ,着重就防渗处理的垂直防渗墙方案设计中考虑的一些主要问题 ,防渗墙施工的深搅法、置换法、挤压法和高喷法四种方法进行了较详细的讨论。最后 ,对改进防渗工程的施工设备、施工方法和环境保护 ,完善施工质量检测手段以及降低施工单价等方面提出了建议。
The engineering scales, geologic conditions of levee foundation and hidden dangerous states of Changjiang's major levees in flood season are introduced. Relatively detailed discussions on some primary problems to be considered in the design schemes of vertical impermeable wall for seepage prevention treatment and four kinds of methods adopted in the construction of impermeable wall, i.e., deep layer mixing method, replacement method, compression method and high pressure injection method, are emphatically conducted. Lastly, some suggestions on improving construction equipments,renovating construction methods and taking note of environment protection in the impermeable wall construction, amending construction quality detection measures, and reducing unit cost price etc., are proposed.
