Construction method of framing reinforcing system for frame bridge underneath passing existing operation line under traffic keeping condition
The invention provides a framing reinforcement system construction method for a frame bridge to pass through an existing operation line under a traffic keeping condition, which comprises the following steps of: S1, closing a road, and keeping the unblocked road unblocked; s2, supporting blocks are laid on the ballast bed along the two sides of the rail, and overhead auxiliary beams are installed on the supporting blocks; s3, constructing a first support body and a second support body below the overhead auxiliary beams on the two sides of the road, constructing a middle support body in the center of the road, constructing a left temporary support body within the width range of a new frame bridge pre-constructed on the closed road, and constructing a fourth temporary support body on the side, away from the closed road, of the guaranteed channel road; and S4, the original frame bridge of the blocked road is dismantled, a first new frame bridge is jacked, the left side temporary supporting body is dismantled step by step, and the first new frame bridge replaces the left side temporary supporting body step by step to support the overhead temporary beam. According to the method, frame bridge construction under the traffic keeping condition is achieved, and the stability of the rail on the overhead temporary beam after the temporary supporting body on the left side is dismantled is guaranteed.
本发明提供一种保通条件下框架桥下穿既有运营线分幅加固体系施工方法，包括以下步骤：S1、封闭一幅道路，保持未封闭道路的畅通；S2、在道床上沿铁轨两侧铺设支撑块，在支撑块上安装架空便梁；S3、在道路两侧架空便梁下方施工第一支撑体和第二支撑体，在道路中央施工中部支撑体，在封闭道路预施工的新框架桥的宽度范围内施工左侧临时支撑体，在保通道路远离封闭道路一侧施工第四临时支撑体；S4、拆除封闭道路的原框架桥，进行第一新框架桥的顶进，逐步拆除左侧临时支撑体，并逐步由第一新框架桥替代左侧临时支撑体对架空便梁进行支撑。该方法实现了保通条件下的框架桥施工，保证了左侧临时支撑体拆除后架空便梁上铁轨的稳定性。
