Temporary supporting grouting bag and temporary supporting method for operating ballastless track of high-speed rail
The invention discloses a temporary supporting grouting bag and a temporary supporting method for operating a ballastless track of a high-speed railway, in the temporary supporting grouting bag, bag bodies and connecting sleeves of a joint limb grouting bag are continuously distributed and connected at intervals to form a joint limb structure, and the bag bodies and the connecting sleeves are communicated with each other, so that each bag body can be filled with grouting slurry, and the grouting efficiency is improved. The width of the connecting sleeve is comprehensively determined according to the width of the bag body and the sleeper spacing of the ballastless track, so that the lower part of the corresponding sleeper is supported by the bag body filled with slurry; a central vertical bag of the multi-limb grouting bag is vertically arranged, at least three bag limbs are transversely distributed and connected to the periphery of the central vertical bag to form a multi-limb structure, and the central vertical bag is communicated with the bag limbs, so that slurry poured into the central vertical bag can be filled into each bag limb. According to the technical scheme, scientific and reasonable stress supporting on the track structure is achieved, meanwhile, the size and the number of the grouting bags are optimized, and the using convenience and the dismounting convenience of the grouting bags are improved.
本发明公开了一种运营高铁无砟轨道的临时支撑灌浆袋及临时支撑方法，临时支撑灌浆袋中，节肢灌浆袋的袋体和连接袖间隔连续分布连接形成节肢结构，袋体和连接袖之间相互贯通，使得灌入浆体能够充入每个袋体，连接袖的宽度根据袋体的宽度和无砟轨道的轨枕间距综合确定，使得相应轨枕下方都由灌入浆体的袋体进行支撑；多肢灌浆袋的中心竖袋竖直设置，至少三个袋肢横置分布连接于中心竖袋的周围形成多肢结构，中心竖袋与袋肢相互贯通，使得灌入中心竖袋的浆体能够充入每个袋肢。通过本发明的技术方案，实现了对轨道结构科学合理受力支撑，同时优化了灌浆袋的尺寸和数量，提高了灌浆袋的使用便利性和拆除便利性。
