格宾生态防护结构在宁夏河道及沟道治理工程中的应用技术指标

Index of application for gabion ecological protective structure in Ningxia river and gully contrul project

宁夏河道和沟道治理中传统采用的铅丝石笼护坡、护脚易因铅丝锈蚀而散架垮塌,干砌石护坡稳定性差、寿命短,给河道防洪安全和沟道排水造成了严重威胁.宁夏引进技术先进、性能优良的格宾结构并应用于河道及沟道岸坡治理工程中,提出了格宾结构的应用范围和原则、选型方法、施工工艺.苦水河格宾岸坡历经30年罕见的洪水后,无垮塌现象,结构完整稳定,运行正常,充分证实了格宾结构用于岸坡防护的良好工程性能.

Traditional iron wire gabion revetment and shield coUapsed easily because of wire rust which was used in river and drainage canals management in Ningxia, and then, dry stone paving is poorly stability and short service life, it caused serious threat to river flood safety and channel drainage. Ningxia introduced gabion with advanced technology and excellent performance structure to project application of river channel revetment and drainage canals regulation. Application technology was researched, and application range of gabion structure and principle, selection method and construction technology were proposed. Gabion structure of Kushui river＇s bank slope withstand rare flood of 30-year return, there is no collapse phenomenon, it＇s structure is complete and stable and running is normal. Gabion structure demonstrated that its good engineering properties and adaptability can be used in riverbank slope protection.
