Frozen soil roadbed side ditch structure and construction method
A permafrost roadbed side ditch structure comprises a permafrost base layer, a roadbed base layer and a roadbed surface layer are sequentially arranged on the permafrost base layer, the permafrost roadbed side ditch structure further comprises a foundation trench, a rigid partition plate set and a side ditch body, the foundation trench is supported on the permafrost base layer, the foundation trench is filled with an inverted filter layer, a drainage pipe is arranged in the inverted filter layer, and the rigid partition plate set comprises an outer side partition plate and an inner side partition plate. The outer side partition plate is arranged on the inverted filter layer, the inner side partition plate is fixedly arranged on the frozen soil base layer and attached to the side walls of the roadbed base layer and the roadbed surface layer, a plurality of water seepage holes are formed in the inner side partition plate, a plurality of capillary tubes extending in the height direction are arranged between the inner side partition plate and the outer side partition plate, and the lower ends of the capillary tubes extend to the inverted filter layer. A sand and gravel piling layer is arranged on the inverted filter layer, and the side ditch body is supported on the sand and gravel piling layer and connected with the top of the outer side partition plate. The structure is simple, construction is convenient, and long-time normal use of the frozen soil roadbed can be guaranteed.
一种冻土路基边沟结构，包括冻土基层，冻土基层上依次设置有路基基层、路基表层，还包括基槽、刚性隔板组、边沟本体，基槽支承在冻土基层上，基槽中填充设置反滤层，且反滤层中布置排水管，刚性隔板组包括外侧隔板、内侧隔板，外侧隔板设置在反滤层上，内侧隔板固定设置在冻土基层上，且与路基基层、路基表层的侧壁贴合，内侧隔板上设置若干渗水孔，内侧隔板、外侧隔板之间排布有若干沿高度延伸的毛细管，各毛细管的下端延伸至反滤层，反滤层上设置砂卵石堆砌层，边沟本体支承在砂卵石堆砌层上，且与外侧隔板的顶部相连。本发明结构简单、施工方便，可保证冻土路基长时间正常使用。
