Pavement subbase layer cushion construction method based on precast beam yard concrete panel
The invention provides a pavement subbase layer cushion layer construction method based on a precast beam yard concrete panel, which comprises the following steps: S1, in a beam yard construction stage, paving a broken stone cushion layer on a roadbed layer, pouring a concrete panel on the broken stone cushion layer, and arranging a breaking joint and an expansion joint; s2, after the small box girder is prefabricated, a pedestal and a track pedestal are broken and removed, and a concrete panel is reserved; s3, the concrete panel is checked, breaking joints and expansion joints on the concrete panel are further cleaned, chippings in notches are removed, the breaking joints are filled with water stop belts, filling materials are embedded into the expansion joints, and waterproof treatment is completed; and S4, paving a water-stable subbase layer on the concrete panel. Materials and manpower in the highway construction process can be saved, construction noise and dust are reduced, the bearing capacity of the pavement structure is improved, the service life of the pavement structure is prolonged, and the later maintenance cost is reduced.
本发明提供了一种基于预制梁场混凝土面板的路面底基层垫层施工方法，包括以下步骤：S1.在梁场建设阶段，在路基层上铺设碎石垫层，在碎石垫层上浇筑混凝土面板，并设置断缝和伸缩缝；S2.在小箱梁预制完成后，对台座及轨道台座进行破除，保留混凝土面板；S3.对混凝土面板进行检查，并进一步对混凝土面板上的断缝和伸缩缝进行清理，去除切口内的碎屑，在断缝内填充止水带，伸缩缝内嵌入填充材料，并完成防水处理；S4.在混凝土面板上摊铺水稳底基层。本发明能够节约公路施工过程中的材料和人力，减少施工噪音和粉尘，提高路面结构的承载力和使用寿命，降低了后期维护费用。
