基辅公路学院水力学教研室研制成功一种涵洞出口河床柔性加固结构。它是用合成材料铺设在整平天然土上的一层柔性防护结构,防护层的一边固定在洞口混凝土铺底的端部(见图)。这种柔性加固代替传统的刚性加固,可把材料用量降低到原来的1/100,工程造价 Kiev Highway College Department of Hydraulic successfully developed a culvert outlet flexible reinforcement structure. It is made of synthetic material laid on the leveling of a layer of natural protective layer of flexible structure, one side of the protective layer is fixed to the end of the concrete laying hole (see photo). This flexible reinforcement instead of the traditional rigid reinforcement, the amount of material can be reduced to the original 1/100, the project cost
