Frost damage prevention and vibration resistance reinforced roadbed structure
The invention discloses a frost damage prevention and vibration resistance reinforced roadbed structure which comprises a coarse-grained soil cushion layer at the bottommost part. A reinforced aluminum matrix composite particle gravel cushion layer, a bell pile lime waste concrete filler cushion layer and a reinforced solidified soil filler cushion layer are included and are sequentially arrangedon the coarse-grained soil cushion layer from bottom to top. A construction method of a dumbbell pile lime waste concrete filler cushion layer comprises the following steps that lime, waste concrete and a filler are mixed and stirred uniformly according to a weight ratio of 4-12: 10-18: 100 and then are laid, and a plurality of dumbbell piles are horizontally buried in the cushion layer at equal intervals. Problems of frost damage and vibration sinking of a heavy haul railway roadbed in a seasonally frozen soil area are solved. Line smoothness is improved, roadbed stability can be kept, roadbed differential settlement is avoided, roadbed damage is reduced, and railway train running safety is guaranteed.
本发明公开一种防冻害与抗振加固路基结构，包括最底部的粗粒土垫层，并且在所述的粗粒土垫层上面从下至上依次还包括加筋铝基复合材料颗粒碎石垫层、铃桩石灰废旧混凝土填料垫层和加筋固化土填料垫层；所述的哑铃桩石灰废旧混凝土填料垫层的构筑方法如下：将石灰、废旧混凝土、填料按重量比4‑12：10‑18：100混合搅拌均匀后铺设，并且在该垫层内部按等间距水平埋设多个哑铃桩，本发明解决季节冻土区重载铁路路基冻害与振陷问题，提高线路平顺性，能够保持路基稳定、避免路基不均匀沉降，减少了路基损伤，保证了铁路列车行驶安全。
