Expressway existing bridge reconstruction construction method
The invention relates to an expressway existing bridge reconstruction construction method, which comprises the following steps: supporting foundation construction: foundation supports are poured at bridge abutments and bridge piers; stress supporting: supports are installed on the foundation supports and therefore, the beam body is supported; cutting and jacking: the bridge pier is cut off through a rope saw, and then the beam body is jacked in place step by step; and support pouring: after the beam body is jacked in place, heightening supporting objects are poured on the bridge abutment and the bridge piers, the heightening supporting objects support the beam body, and therefore lifting and heightening of the bridge are completed, a new bridge is built, and the new bridge and the old bridge are spliced into a whole. The method has the effect of reducing resource waste in the old bridge transformation process.
本申请涉及一种高速公路既有桥梁改造施工方法，包括以下步骤：支撑基础施工：在桥台和桥墩处浇筑基础支撑物；受力顶撑：在基础支撑物上安装顶撑物，从而将梁体顶撑；切断顶升：使用绳锯将桥墩切断，然后将梁体分步顶升到位；顶撑浇筑：将梁体顶升到位后，在桥台和桥墩上浇筑增高支撑物，增高支撑物对梁体进行支撑，从而完成桥梁的抬升加高，建筑新桥并将新桥与旧桥拼接成为一体。本申请具有减少旧桥梁改造过程中的资源浪费的效果。
