Railway ballastless track temporary transition supporting structure and ballastless track dismounting and replacing method
The invention discloses a railway ballastless track temporary transition supporting structure and a ballastless track dismounting and replacing method, belongs to the field of track construction, and aims to guarantee normal operation and wide application range. The temporary sleepers are supported on the lower foundation through the supporting supports, so that the ballastless track supporting layer and the lower structure are detached and replaced under the condition that the track is not broken, and the influence on driving is small. The supporting seats used for supporting the temporary sleepers are connected to the lower foundation of the ballastless track through the anchor bolts, so that the integrity and the stability of the temporary transition track structure are improved. The temporary sleepers are directly supported by the supporting supports, the supporting supports between the adjacent temporary sleepers are mutually independent, and the temporary sleepers and the supporting supports are adjustable in the vertical direction. The temporary sleeper can adapt to special sections of ballastless tracks such as small-radius curves, sections with ultrahigh curves, telescopic adjusters or turnout zones and the like by adjusting the height between the temporary sleeper ends and the supporting supports, is wide in application range, and is applicable to ballastless track diseases and lower structure diseases.
本发明铁路无砟轨道临时过渡支撑结构及无砟轨道拆换方法，属于轨道施工领域，目的是保证正常运营同时确保适用范围广。临时轨枕通过支撑支座支撑于下部基础上，实现了在不断道的情况下对无砟轨道支撑层以及下部结构进行拆换，对行车影响小。用于支撑临时轨枕的支撑支座通过锚固螺栓连接于无砟轨道的下部基础上，提高了临时过渡轨道结构的整体性和稳定性。支撑支座直接支撑临时轨枕，且相邻临时轨枕之间的支撑支座相互独立，且临时轨枕沿竖向与支撑支座可调，可通过临时轨枕端头与支撑支座之间的高度调节来适应如小半径曲线、曲线超高地段落、伸缩调节器或道岔区等无砟轨道特殊地段，使用范围广，且无砟轨道病害以及下部结构发生的病害均适用。
