Steel-concrete composite beam cable-stayed bridge
The invention discloses a steel-concrete composite beam cable-stayed bridge, and relates to the technical field of bridge construction. The bridge comprises a truss girder, wherein the truss girder is fixed by a cross beam and a longitudinal beam, a connecting inclined rod is fixed between the truss girder and the cross beam, an air inlet is formed in the surface of the longitudinal beam, a flood control device used for improving a flood control effect of the longitudinal beam is arranged in the longitudinal beam, the flood control device comprises a transmission mechanism, a surface decontamination mechanism, a filter screen cleaning mechanism and a crushing mechanism, the transmission mechanism comprises a hinged plate, a torsional spring, a first support, a vertical plate, a second support, a telescopic rod, a filter screen support, a fixed cylinder and a filter screen, one end of the hinged plate is hinged into the longitudinal beam, and the hinged position of the hinged plate is fixed to one end of the torsional spring. The air inlet of the device can ensure that the filter screen is automatically opened when a flood occurs and strong wind occurs, so that the flowability of water is improved, the impact force caused by the flood is reduced for the whole longitudinal beam, and the service life of the longitudinal beam is prolonged.
本发明公开了一种钢混组合梁斜拉桥，涉及桥梁建设技术领域。包括桁架梁，所述桁架梁通过纵梁与横梁固定，所述桁架梁与横梁之间固定有连接斜杆，所述纵梁的表面开设有进风口，所述纵梁内设置有用于提高纵梁的防洪效果的防洪装置，所述防洪装置包括传动机构、表面除污机构、过滤网清洁机构和粉碎机构，所述传动机构包括铰接板、扭簧、一号支架、竖板、二号支架、伸缩杆、过滤网支架、固定圆筒和过滤网，所述铰接板的一端铰接在纵梁内，所述铰接板铰接处与扭簧的一端固定。该装置设置的进风口能够保证在发生洪涝起大风时，自动打开过滤网，增加水的流动性，为整个纵梁减少洪水造成的冲击力，从而了纵梁的使用寿命。
