Trapezoidal sleeper bottom-to-top grouting bag construction method and trapezoidal sleeper system
The invention discloses a construction method for grouting bags from bottom to top for a trapezoidal sleeper and a trapezoidal sleeper system.The construction process of the method includes the steps that a base is poured firstly, then the trapezoidal sleeper is laid, then the grouting bags are pasted and poured, grouting materials in the grouting bags are condensed and hardened, supporting is provided for the trapezoidal sleeper, and then side blocking tables are poured; the bottom of the longitudinal beam of the trapezoidal sleeper is prevented from being adhered to the concrete of the base, so that a wrapping sleeve is not required to be sleeved, the problems of voids, pitted surfaces and empty hoisting are avoided, and the phenomenon of'collision between hardness' of the sleeper bottom is more difficult to occur and the observation and maintenance of the sleeper bottom are easier due to the fact that the grouting bag adopts point-type support and the distance between the sleeper bottom and the base is farther.
本发明公开了一种梯形轨枕自下而上灌浆袋施工方法及梯形轨枕系统，该方法的施工工艺中，采用先浇筑底座而后铺装梯形轨枕，接着粘贴、灌注灌浆袋，通过灌浆袋中的灌浆料凝结硬化，为梯形轨枕提供支承，再浇筑侧边挡台的施工方式，避免了梯形轨枕纵梁底部与底座混凝土的粘连，因此不需要套装包裹套，杜绝了蜂窝麻面和空吊问题，且因灌浆袋为点式支撑，枕底与底座相距更远，因此更不易发生枕底“硬碰硬”现象、更易于枕底的观察与检修。
