Ballastless track structure foundation settlement repairing method
The invention discloses a ballastless track structure foundation settlement repairing method. The method comprises the following steps: determining a settlement area range, and measuring settlement data of a settlement area; digging construction planes with set depths above and below the foundations on the two sides of the settlement area, and enabling the construction planes to extend into the lower end of the base plate by a set width; casting a concrete supporting platform in place on the construction plane, and performing curing and hardening; installing a lifting device on the concrete supporting platform to support the base plate; lifting the base plate by a set height through a lifting device, and forming mechanical support for the state of the lifting device through a mechanical self-locking assembly on the lifting device; pouring mortar between the lifted base plate and the foundation, and curing and hardening the poured mortar; and repeating the steps S5-S6 till the foundation and the ballastless track structure meet the design requirement, then dismantling the lifting device, backfilling the construction plane on the foundation to the initial state, and compacting backfilled soil.
本发明公开了一种无砟轨道结构地基沉降修复方法，本发明包括如下步骤：确定沉降区域范围，并测量沉降区域的沉降数据；在沉降区域两侧的地基上下挖设定深度的施工平面，并让施工平面伸入到底座板下端设定宽度；在施工平面上现浇混凝土支撑平台，并进行养护硬化；在混凝土支撑平台上安装抬升装置，对底座板形成支撑；通过抬升装置对底座板进行抬升设定高度，并通过抬升装置上的机械自锁组件对抬升装置的状态形成机械支撑；在抬升后的底座板与地基之间灌注砂浆，并对灌注的砂浆进行养护硬化；重复步骤S5‑S6，直至地基和无砟轨道结构满足设计要求后，拆除抬升装置，对地基上的施工平面进行回填至初始状态，并对回填土进行压实。
