Novel arched rigid frame bridge and lateral rotation construction method thereof
The invention discloses a novel arched rigid frame bridge and a lateral rotation construction method thereof, and relates to the technical field of arched rigid frame bridges, according to the technical scheme, the novel arched rigid frame bridge comprises a V-shaped rigid frame section and a pier foundation, the V-shaped rigid frame section comprises a side arch section, a middle arch section and a bridge road beam, a bottom face is arranged on the side, away from the bridge road beam, of the joint of the side arch section and the middle arch section, and a spherical hinge is arranged at one end of the bottom face; the pier foundation is provided with side horizontal grooves corresponding to the side arch sections and the middle arch sections and fixing grooves corresponding to the connecting positions of the side arch sections and the middle arch sections, and spherical hinge grooves rotationally connected with spherical hinges are further formed in the intersecting positions of the two side horizontal grooves and the fixing grooves. The joint of the side arch section and the middle arch section is inserted into the fixing groove, and the spherical hinge is inserted into the spherical hinge groove and rotationally connected with the spherical hinge groove. During swivel construction, a temporary construction tower and a support do not need to be arranged, a large bridge pier foundation bearing platform does not need to occupy the floor area, and the bridge pier foundation is simple in structure and low in construction difficulty and has a good application prospect in small-span arch bridge construction.
一种新型拱形刚构桥及其侧向转体施工方法，涉及拱形刚构桥技术领域，所采用的技术方案包括V形刚构节段、桥墩基础，V形刚构节段包括边拱段、中拱段和桥道梁，边拱段、中拱段连接处远离桥道梁的一侧设置有底面，底面一端设置有球铰；桥墩基础设置有分别与边拱段、中拱段对应的侧卧槽，以及与边拱段、中拱段连接处对应的固定槽，两侧卧槽与固定槽相交处还设置有与球铰转动连接的球铰槽；边拱段、中拱段连接处插入固定槽，球铰插入球铰槽且与球铰槽转动连接。本发明在转体施工时无需设置临时施工塔架、支架，也无需较大的桥墩基础承台占地面积，且桥墩基础结构简单，施工难度低，在小跨径的拱桥施工中具有较好的应用前景。
