In-situ pouring replacement method for elastic supporting block sleeve shoe
The invention discloses an in-situ pouring replacement method for an elastic supporting block sleeve shoe. The in-situ pouring replacement method comprises the steps that the damaged position of the elastic supporting block sleeve shoe is determined; the fasteners, corresponding to the peripheries of the elastic supporting blocks, of the damaged sleeve shoes are detached; the steel rails are lifted by a preset height, and meanwhile the corresponding elastic supporting blocks are lifted; taking out or removing the damaged and invalid sleeve shoe, and fixing an elastic cushion plate and an elastic cushion strip at the bottom of the elastic supporting block; the steel rails and the supporting blocks are descended in place, and the fasteners are installed again and fine adjustment is carried out; and a sleeve shoe pouring auxiliary tool is installed, a liquid sleeve shoe material is injected into a cavity formed between the supporting block and the ballast bed through the sleeve shoe pouring auxiliary tool, and after the material is solidified to form a sleeve shoe again, the sleeve shoe pouring auxiliary tool is dismantled. By means of the technical scheme, the construction organization is optimized, the construction efficiency is improved, the problem that according to a traditional method, the number of skylight procedures is large, the procedure connection time is long, and consequently the overall replacement efficiency is low is solved, and the boot repairing quality of the elastic supporting block is guaranteed.
本发明公开了一种弹性支承块套靴的原位浇筑更换方法，包括：确定弹性支承块套靴的损坏位置；将损坏套靴对应弹性支承块周边的扣件拆除；将钢轨提升预设高度，同时将对应弹性支承块提起；取出或拆除伤损失效套靴，并在弹性支承块底部固定弹性垫板和弹性垫条；将钢轨和支承块降落就位，重新安装扣件并进行精调；安装套靴浇筑辅助工装，并将液体套靴材料通过套靴浇筑辅助工装注入支承块与道床之间形成的空腔内，材料固化重新形成套靴后，拆除套靴浇筑辅助工装。通过本发明的技术方案，优化了施工组织，提高了施工效率，解决了传统方法存在的天窗工序较多以及工序衔接时间长导致的整体更换效率较低的问题，保证了弹性支承块的套靴修复质量。
