Permafrost region prefabricated hollow slab base course pavement structure capable of increasing the construction speed
The invention discloses a permafrost region prefabricated hollow slab base course pavement structure capable of increasing the construction speed. The permafrost region prefabricated hollow slab basecourse pavement structure comprises a graded gravel cushion layer, a prefabricated hollow slab base course, a graded broken stone layer and an asphalt surface layer which are sequentially laid from bottom to top. The prefabricated hollow slab base layer comprises prefabricated hollow slabs arranged in an N * M matrix; H hollow holes are formed in each prefabricated hollow plate at equal intervals;in the longitudinal direction of the road, polygonal cast-in-place belts with the same width are formed between every two of the N prefabricated hollow plates in each column, and the number of the Nprefabricated hollow plates in each column is made to form a whole by pouring cement-based grouting materials; and in the transverse direction of the road, every two of the M prefabricated hollow slabs in each row are attached and spliced, the H hollow holes of the M prefabricated hollow slabs are aligned, and heat dissipation through holes communicating with the ambient atmosphere are formed. Thehollow holes are adopted to conduct heat, the effect of protecting frozen soil is achieved, the prefabricated hollow slabs can improve the construction speed and stability, and the prefabricated hollow slabs can be widely applied to highway construction in permafrost regions.
本发明公开了一种能加快施工速度的多年冻土区预制空心板基层路面结构，包括从下至上依次铺设的级配砂砾垫层、预制空心板基层、级配碎石层和沥青面层；预制空心板基层包括呈N*M矩阵排列的预制空心板；每块预制空心板中均等距设有H个空心孔；沿道路纵向，每列中的N块预制空心板块两两之间均形成等宽的多边形现浇带，通过浇筑水泥基灌浆料，使得每列中的N块预制空心板块数形成一个整体；沿道路横向，每行中的M块预制空心板两两之间均相贴合拼接，M块预制空心板的H个空心孔均对齐，形成与环境大气相连通的散热通孔。本发明采用空心孔疏导热量，具有保护冻土的作用，预制空心板能够提高施工速度和稳定性，能广泛应用于多年冻土区公路建设中。
