High-speed rail ballastless track roadbed pavement structure in seasonal frozen soil region
The invention discloses a high-speed rail ballastless track roadbed pavement structure in a seasonal frozen soil region, which is used for inhibiting roadbed frost heaving, and relates to the technical field of high-speed rail ballastless tracks in the seasonal frozen soil region, the high-speed rail ballastless track roadbed pavement structure comprises a pavement structure main body, the pavement structure main body comprises a filler layer and a concrete cover layer covering the outer side of the filler layer, a ventilation opening is formed in the top of the pavement structure main body, penetrates through the concrete cover layer and is communicated with the filler layer, so that water vapor generated in the subgrade in summer is discharged, and the ventilation opening is provided with a waterproof ventilation structure. High-temperature water vapor generated in the subgrade in summer can be discharged and prevented from being gathered and condensed into water on the upper portion of the subgrade, so that the'pot cover effect 'of a ballastless track of the high-speed railway subgrade is restrained, and the purpose of reducing frost heaving in winter is achieved.
本发明公开了一种季节冻土区高铁无砟轨道路基路面结构，用于抑制路基冻胀，涉及季节冻土区高铁路基无砟轨道技术领域，包括路面结构主体，所述路面结构主体包括填料层以及覆盖于所述填料层外侧的混凝土盖层，所述路面结构主体的顶部开设有透气口，所述透气口贯穿所述混凝土盖层，并与所述填料层连通，以使夏季路基内产生的水汽排出，且所述透气口设置有防水透气结构。本发明能够使夏季路基内产生的高温水汽排出，防止水汽在路基上部汇集凝结成水，从而抑制高铁路基无砟轨道的“锅盖效应”，达到冬季减小冻胀的目的。
