Impact-resistant and wear-resistant surface protection structure of hydraulic release structure and construction method
The invention discloses an impact-resistant and wear-resistant surface protection structure of a hydraulic release structure and a construction method. I-shaped steel is arranged at the bottom of the surface protection structure, and arranged on lower structural concrete at certain intervals in the water flow direction and connected with the lower structural concrete through n-shaped joint bars; rails are arranged on the upper part of the I-shaped steel, the axis direction of the rails is the same as the water flow direction, and the rails are arranged in the axis direction of the I-shaped steel at certain intervals and reliably welded to the I-shaped steel at the intersection positions; and flat steel is arranged in the rail gap, is arranged at a certain interval in the water flow direction, is perpendicular to the concrete surface of the lower structure, and is reliably welded to the I-shaped steel or the joint bars. Concrete is backfilled in gaps between the rails and the I-shaped steel and poured to a position with a certain distance from the top surfaces of the rails; and epoxy concrete is a gap filling material between the rails with a certain thickness, and the top surface of the epoxy concrete is flush with the top surfaces of the rails. The impact-resistant and wear-resistant surface protection structure is good in toughness, high in impact resistance, convenient to construct, low in later maintenance cost and capable of effectively resisting impact damage of large-particle-size bed loads.
本发明公开了一种水工泄水建筑物抗冲耐磨护面结构及施工方法，工字钢设置于护面结构底部，沿水流方向间隔一定距离布置于下部结构混凝土之上，通过“ㄇ”型插筋与下部混凝土连接；钢轨设置于工字钢上部，钢轨轴线方向与水流方向相同，沿工字钢轴线方向间隔一定距离布置且在相交部位与工字钢可靠焊接；扁钢设置于钢轨间隙内并沿水流方向间隔一定距离布置，扁钢与下部结构混凝土表面垂直，扁钢应与工字钢或插筋可靠焊接。在钢轨及工字钢间隙内回填混凝土，浇注至距钢轨顶面一定距离处；环氧混凝土为一定厚度的钢轨间填缝材料，顶面与钢轨顶面齐平。该结构韧性好、抗冲击性能强、施工方便、后期维护成本低，可有效抵抗大粒径推移质的冲击破坏。
