Bridge and culvert extension side line protection structure and construction method
The invention relates to the technical field of bridge and culvert construction, and discloses a bridge and culvert extension side line protection structure and a construction method.The bridge and culvert extension side line protection structure comprises an existing box-type bridge wing wall, an advanced small guide pipe is arranged on the roadbed soil side of the existing box-type bridge wing wall 1, a mounting groove is formed in the existing box-type bridge wing wall, and a corrugated steel plate retaining wall is fixedly mounted in the mounting groove; one end of the bottom of the mounting groove is fixedly connected with a blocking steel plate, and the blocking steel plate and the bottom of the mounting groove define an anchoring cavity; according to the method, a seamless track does not need to be cut, the corrugated steel plate retaining wall is used for replacing an existing wing wall part cut by a rope saw, roadbed filling soil is effectively supported and retained, a roadbed soil volley surface formed after the existing wing wall is cut is supported, the construction safety of the lengthened box bridge and the operation safety of the track are ensured, the operation of the existing track is not influenced, and the construction period is shortened. And the defects of long construction period, high investment and requirement on speed-limiting operation of the existing line are overcome.
本发明涉及桥涵施工技术领域，公开了一种桥涵接长侧线路防护结构及施工方法，包括既有箱型桥翼墙，既有箱型桥翼墙1的路基土侧设置有超前小导管，既有箱型桥翼墙上开设有安装槽，安装槽内固定安装有波纹钢板挡墙，安装槽底部一端固定连接有封堵钢板，封堵钢板与所述安装槽的底部合围成锚固腔体；本发明无需对无缝线路进行切割，利用波纹钢板挡墙替代绳锯所切割的既有翼墙部分，具有对路基填土的有效支挡，实现了对既有翼墙切割后形成路基土凌空面的支护，确保接长箱型桥施工安全以及线路的运营安全，不影响既有线的运营，还克服了施工周期长，投资大，要求既有线限速运行的缺点。
