Small-span rigid framework cantilever slab renovation structure suitable for upward arching of roadbed
The invention discloses a small-span rigid framework cantilever slab renovation structure suitable for upward arching of a roadbed. The small-span rigid framework cantilever slab renovation structurecomprises a column body structure and a cantilever slab beam; one part of the lower end of the column body structure is arranged below an upper arch geology, and the other part of the upper end of thecolumn body structure penetrates through the upper arch geology; the upper end of the column body structure is connected with the cantilever plate beam; a void layer is arranged between the cantilever plate beam and the surface of the roadbed; and the column body structure comprises a pile foundation and a pier column, a separation layer is arranged around the side wall of the pier column, and the separation layer is filled with emulsified asphalt. By arranging the void layer, it can be directly avoided that when the roadbed arches upwards, the surface of the roadbed possibly lifts the cantilever plate beam at first; the separation layer is arranged around the side wall of the pier column, the separation layer is filled with the emulsified asphalt, the acting force between the pier columnand the upwarp geology around the pier column can be relieved, the rock mass can be prevented from generating the lifting effect on the pier column in the continuous upwarp process, and therefore thesituation that the cantilever plate beam is lifted accordingly, and rail structure deformation is caused is avoided.
本发明公开了一种适用于路基上拱的小跨度刚构悬臂板整治结构，包括柱体结构、悬臂板梁；柱体结构的下端一部分置于上拱地质下方，柱体结构的上端另一部分穿过上拱地质设置；柱体结构的上端与悬臂板梁连接；悬臂板梁与路基表面之间设置有脱空层；柱体结构包括桩基、墩柱，围绕墩柱的侧壁设置有分隔层，在分隔层内填塞有乳化沥青。通过设置脱空层，可以直接避免在路基上拱时候路基表面首先可能对悬臂板梁造成的抬升；通过围绕墩柱的侧壁设置分隔层，并在分隔层内填塞有乳化沥青，能缓解墩柱与其周围上拱地质间的作用力，可以避免岩体在继续上拱的过程中对墩柱产生托举效应，从而避免悬臂板梁随之抬升，造成轨道结构变形。
