Orifice flood discharge structure in concrete dam
The invention relates to the technical field of concrete dams, in particular to an orifice flood discharge structure in a concrete dam. The structure comprises an orifice steel liner arranged along awater flow direction, wherein a concrete structure is poured around the orifice steel liner, the orifice steel liner comprises a plurality of steel liner sections which are sequentially connected andarranged, and the steel liner sections each comprise a top plate, a left side plate, a bottom plate, a right side plate, a first connecting folded plate, a second connecting folded plate, a third connecting folded plate and a fourth connecting folded plate. Welding seams formed by welding of the components are butt welding seams, the butt welding seams are more convenient for groove cutting and welding construction compared with fillet welding seams formed by welding in the prior art, the thickness of the periphery of the butt welding seams is consistent, the welding quality and reliability are improved, a detection operation surface is a plane, and the detection of the welding quality is also convenient. Moreover, the four corner edges of the steel liner sections are not right angles, sothat the problem of stress concentration at the four right-angle corner edges is avoided, the concrete structure is more favorable for vibrating and compacting, and the construction quality is improved.
本发明公开涉及混凝土坝技术领域，尤其涉及一种混凝土坝内的孔口泄洪结构，其包括沿水流方向设置的孔口钢衬，孔口钢衬的四周浇筑有混凝土结构，孔口钢衬包括多个依次连接设置的钢衬节，钢衬节包括顶板、左侧板、底板、右侧板、第一连接折板、第二连接折板、第三连接折板、第四连接折板，各部件采用焊接形成的焊缝为对接焊缝，对接焊缝相对于现有技术中焊接所形成的角焊缝，更加方便切坡口和焊接施工，对接焊缝周边厚度一致，焊接质量及可靠性均得到提高，检测作业面为平面，也便于焊接质量检测。并且，钢衬节的四个角缘处不是直角，避免了四个直角角缘处应力集中的问题，更加利于混凝土结构振捣密实，提高施工质量。
