Ballast bed settlement transformation construction method
The invention discloses a ballast bed settlement transformation construction method, which belongs to the technical field of rail transit, and comprises the following steps: detecting a ballast bed, and determining a settlement area of the ballast bed and settlement parameters of the settlement area; the steel rails in the settlement area are dismantled; according to the settlement parameters, a groove extending in the transverse direction is formed in one side of the original sleeper in the settlement area; replacing sleepers are placed in all the grooves, and all the replacing sleepers are installed in the grooves; arranging a plurality of steel bars around the replacement sleeper; and concrete is poured in the settlement area until the poured concrete completely submerges all the steel bars, and a new ballast bed is formed after solidification. The invention provides a ballast bed settlement transformation construction method which can adapt to large-area high-settlement ballast bed settlement characteristics, synchronous construction of large-area ballast bed settlement can be achieved, accurate adjustment of ballast bed high-settlement can be guaranteed, and therefore in the limited construction skylight period, the ballast bed settlement transformation construction method is suitable for large-area high-settlement ballast bed settlement. And high-efficiency and high-accuracy transformation of a ballast bed settlement area is ensured.
本发明公开了一种道床沉降改造施工方法，属于轨道交通技术领域，包括以下步骤：检测道床，确定道床的沉降区域以及沉降区域的沉降参数；拆除沉降区域内的钢轨；根据沉降参数，在沉降区域内的原轨枕一侧开设沿横向延伸凹槽；在各个凹槽内均放入替换轨枕，将各个替换轨枕安装在凹槽中；在替换轨枕周围布置若干钢筋；在沉降区域内浇筑混凝土，直至浇筑混凝土完全淹没各钢筋，固化后形成新的道床。本发明提供了一种道床沉降改造施工方法，其能够适应大区域高沉降的道床沉降特性，不仅能够实现大区域道床沉降的同步施工，还能够确保对道床高沉降的准确调整，进而使得在有限的施工天窗期内，保证对道床沉降区域的高效率高准确度的改造。
