Overall stability of previous tetrahedron permeable framework in waterway regulation engineering is poor,and its bars are easy to take off the welding.Aiming at the deficiency,the research on the geometric shape,processing,construction technology of the new water permeable frame is carried out.The twisted double “H” permeable frame is invented and is used for the first time in the 12.5 m deep-water channel of the Yangtze River below Nanjing.The monitoring results show that its overall stability is good,and it can effectively reduce the velocity of flow and the effect of energy dissipation is obvious.
