Segmental prefabricated concrete string arch bridge
The invention provides a segmental precast concrete string arch bridge which comprises an arch bridge body of an arc-shaped structure, the arch bridge body is formed by splicing a plurality of arch bridge sections of the arc-shaped structure, the two sides of the arch bridge body in the length direction are each provided with a bridge pier, and a plurality of horizontal and parallel steel bar inhaul cables are arranged below the arch bridge body in the length direction of the arch bridge body. The steel bar inhaul cable is in a tensioned state, the two ends of the steel bar inhaul cable are fixedly connected to the bridge piers, a plurality of vertically-arranged supporting rods are arranged on the steel bar inhaul cable in the length direction of the steel bar inhaul cable, and the top ends of the supporting rods are located at the joint of the arch bridge sections. Compared with a traditional arch bridge, the arch bridge body composed of the prefabricated arch bridge sections is directly spliced and installed on site, and cost is low. The lower side of the arch bridge body is supported through the supporting rods, force is transmitted to the bridge piers through the steel bar inhaul cables, the problem that supporting force is insufficient due to the fact that the bridge piers cannot be arranged in the middle of a large-span arch bridge is effectively solved, and compared with a traditional arch bridge, the arch bridge is firmer and more durable.
本发明提供了一种节段预制混凝土张弦拱桥，包括呈弧形结构的拱桥体，所述拱桥体由多个呈弧形结构的拱桥段拼接构成，拱桥体长度方向的两侧各设有一个桥墩，拱桥体的下方沿其长度方向设有多根呈水平且相互平行设置的钢筋拉索，所述钢筋拉索呈拉紧状态，钢筋拉索的两端固定连接于桥墩上，钢筋拉索上沿其长度方向设有多个呈竖直设置的支撑杆，所述支撑杆的顶端位于拱桥段拼接处。本发明设置由预制拱桥段构成的拱桥体，相较于传统拱桥，直接在现场拼接安装即可，成本低廉。通过支撑杆对拱桥体下侧进行支撑，并将力量通过钢筋拉索传递至桥墩，有效克服了大跨距拱桥因中部无法设置桥墩造成的支撑力不足问题，相较于传统拱桥更加结实耐用。
