Construction method of semi-sunken self-balancing fusiform double-arch fabricated overpass
The invention discloses a construction method of a semi-sunken self-balancing fusiform double-arch fabricated overpass, which belongs to the technical field of roads and bridges, and is arranged at a crossroad. The method comprises the following steps that A, site preparation is performed; B, the lower arch prefabricated parts are hoisted to the designated position, and then the lower arch prefabricated parts are connected to form a second arch bridge; C, the supporting column is hoisted to the designated position and connected with the lower arch prefabricated part; and D, the upper arch prefabricated part is hoisted to a designated position, then the upper arch prefabricated part is connected with the supporting columns to form a first arch bridge, and the prefabricated parts at the two ends of the first arch bridge and the second arch bridge are connected through mortise and tenon joint structures. By adopting a double-arch form, passing of vehicles and pedestrians in all directions cannot be affected at the crossroad, an existing traffic light system can be omitted, and rapid passing of the vehicles and the pedestrians is achieved; and the second arch bridge is a sunken structure, the first arch bridge can be prevented from being too high, the bridge floor is prefabricated in a factory and installed on site, and rapid construction can be achieved.
本发明公开了一种半下沉式自平衡梭形双拱装配式立交桥的施工方法，属于道路桥梁技术领域，设置在十字路口，包括以下步骤：步骤A、场地整理；步骤B、吊装下拱预制件至指定位置，然后连接各下拱预制件形成第二拱桥；步骤C、吊装支撑柱至指定位置并与下拱预制件连接；步骤D、吊装上拱预制件至指定位置，然后将上拱预制件与支撑柱相连形成第一拱桥，第一拱桥和第二拱桥两端的预制件通过榫卯结构相连。本发明通过采用双拱的形式，在十字路口不会影响各方向车辆和行人的通行，可以省去现有的红绿灯系统，实现车辆和行人的快速通行；第二拱桥采用下沉式的结构，可以避免第一拱桥过高，桥面采用工厂预制、现场安装的方式，可以实现快速施工。
