Railway platform structure capable of reducing differential settlement of platform and construction method
The invention provides a railway platform structure capable of reducing differential settlement of a platform and a construction method, and belongs to the technical field of building construction.The railway platform structure structurally comprises embedded steel bars fixed to a platform wall cap, the lower portions of the embedded steel bars are filled with graded broken stone, and due to the reasonable configuration of graded broken stone particles, large particles form a stable framework, and therefore the stable framework is formed; large-particle gaps are filled with the secondary particles, so that the filler is compact, compared with common soil, the filler has good water permeability, the drainage consolidation speed is high in the compression process, the compression stabilization time is short, and after the graded broken stones are compacted, a skeleton structure with high shear strength, stable structure, large bearing capacity and small settlement deformation can be formed; the concrete cushion layer with a certain thickness is poured on the top of the graded broken stone, the platform bricks are laid on the concrete cushion layer, and the structure can effectively avoid differential settlement caused by conventional soil body filling.
本发明提出了一种减少站台不均匀沉降的铁路站台结构及施工方法，属于建筑施工技术领域，其结构包括固定在站台墙墙帽的预埋钢筋，预埋钢筋下方填充有级配碎石，该级配碎石由于级配碎石颗粒的合理配置，大颗粒形成稳定骨架，次颗粒填充大颗粒空隙，使填料不仅密实，与普通土相比，具有良好的透水性，在压缩过程中排水固结速度快，压缩稳定时间短，且级配碎石压实后可形成抗剪强度高，结构稳定，承载力大，沉降变形较小的骨架结构，在级配碎石顶部浇筑一定厚度的混凝土垫层，混凝土垫层上方铺设站台砖，该结构可有效的避免采用常规土体填充导致不均匀沉降。
