唐河定州段综合整治一期工程堤防施工技术

在唐河定州段河道综合整治一期工程中，堤防结构设计有一定的代表性，它的主体为沙堤结构，迎水坡设计有粘土防渗体，防渗体迎水面有格宾网石笼护坡和护脚；防渗体与格宾网石笼护坡之间铺设土工布，防渗体基础与格宾网石笼护脚之间铺设土工膜，结构较复杂，施工难度大。该工程施工的过程、难点、技巧在同类工程施工中具有重要的借鉴作用。

Analysis for Embankment Construction Techniques in Tanghe River Dingzhou Section Comprehensive Treatment Project Phase I

The embankment structure design is a typical representative in the first phase of Tanghe River Dingzhou section comprehensive treatment project. The main body is a sand embankment structure, upstream slope is partly constructed by clay impervious body, there is gabion mesh retaining pin in the upstream side of impervious body; the geotextile is laied between sand embankment and impervious body, geomembrane is laied between impervious body and gabion mesh gabion retaining pin. The embankment structure design is scientific, the difficulty of construction is great. This article introduces the process, difficulties and techniques in construction, it can be a reference for similar construction of embankment project.
