Construction method of fabricated bridge
The invention discloses a construction method of a fabricated bridge. The construction method comprises the following steps that arch foot supports, stiff skeleton supports and arch rib supports are installed; a cross beam is mounted at the top ends of the arch foot bracket and the stiff skeleton bracket; mounting the stiff skeleton on the cross beam; arch rib shells are synchronously installed from the two ends of the arch bridge to the middle; mounting the tie bar bottom die on the stiff skeleton to form an initial bridge; the initial bridge frame is hoisted and installed on a tied-arch bridge support; arch feet are formed on the stiff framework in a pouring mode; the arch foot supports are dismantled, and concrete is poured into the arch rib shells to form arch ribs; a tie bar is formed by pouring in the tie bar bottom die; performing bridge floor construction to form a bridge floor; guardrails are installed on the bridge floor, asphalt is laid, and the tied-arch bridge is formed. According to the method, the initial bridge frame is formed through pre-installation outside the river channel, then the initial bridge frame is hoisted to the preset installation position to complete construction, the construction speed on the land is high, the installation period is short, and the influence on the river reach where the preset installation position is located is reduced.
本发明公开了一种装配式桥梁的施工方法，包括以下步骤：安装拱脚支架、劲性骨架支架和拱肋支架；在拱脚支架和劲性骨架支架的顶端安装横梁；将劲性骨架安装在横梁上；自拱桥的两端向中间同步安装拱肋壳体；将系杆底模安装在劲性骨架上，形成初始桥架；将初始桥架吊装并安装至系杆拱桥支架；在劲性骨架上浇筑形成拱脚；拆除拱脚支架，并在拱肋壳体内浇筑混凝土形成拱肋；并在系杆底模内浇筑形成系杆；进行桥面施工形成桥面；在桥面上安装护栏，铺设沥青，形成系杆拱桥。本发明通过在河道外预先安装形成初始桥架，再将初始桥架吊装至预设安装位置完成施工，在陆地上施工速度快，安装周期短，减小了预设安装位置所在河段收到的影响。
