混凝土四面六边透水框架群技术在河道整治、护岸及抢险中的应用

Application of Tetrahedron-Like Concrete Penetrating Frames in River Improvement,Bank Protection and Emergency Work

混凝土四面六边透水框架是一种新型江河透水护岸工程技术.通过室内试验,研究了四面六边透水框架淤滩固脚护岸的可行性,以及透水框架布设方式、结构尺寸对减速落淤的影响.在室内试验研究成果的基础上,将四面六边透水框架用于实际护岸工程中.室内试验和实际工程应用均表明,这种新型的透水框架具有十分明显的减速落淤效果,护岸效果优于传统的护岸工程技术,是一项值得大力推广的护岸新技术.

The probability of using tetrahedron-like concrete penetrating frame for bank protection, the effects of its space layout and structural dimension on decelerating flow and promoting sedimentation were studied by experiments in the laboratory. Based on the experimental results, the tetrahedron-like penetrating frame was used in actual projects. Studies in the laboratory and actual projects show that this type of frame has evident functions in decelerating flow and promoting sedimentation. Moreover, it has a better effect on bank protection than traditional technologies, so it is a new technology worth generalizing.
