Reinforcing method of existing operating railway overpass
According to the reinforcing method of the existing operating railway flyover, the soil body in the reinforcing area is reinforced through the first reinforcing slurry, the raft foundation connected with the bridge foundation is manufactured, and the frame culvert is poured to jack the bottom of the bridge, so that comprehensive reinforcing of the flyover is achieved; the influence of disturbance deformation of the stratum on the railway line and the overpass during construction of the shield underneath passing the railway overpass is eliminated, normal operation of the railway line is not affected, the construction period can be guaranteed, and the reinforcing method is wide in application range, easy to construct, low in cost, high in safety and suitable for popularization and application. A soil body reinforcing measure and a bridge foundation reinforcing measure can be reserved and fully utilized, the old overpass is permanently reinforced, and the operation safety of subsequent railways and subway lines is guaranteed.
本申请提供有一种既有运营铁路立交桥的加固方法，通过对加固区域内的土体用第一加固浆料加固，制作与桥基础连接的筏板基础，并浇制框架涵顶托桥梁底部，实现对立交桥的全面加固，消除在盾构下穿铁路立交桥施工时地层的扰动变形对铁路路线和立交桥的影响，既不影响铁路线路的正常运行又可以保证施工工期，而且本申请加固方法适用范围广、施工简单、成本低、安全性高，土体加固措施及桥基础加固措施还可以保留下来充分利用，永久加固老旧立交桥，保证后续铁路及地铁线路的运行安全。
