High-speed rail ballastless track base plate construction method
The invention provides a high-speed rail ballastless track base plate construction method. The construction method of a high-speed rail ballastless track base plate comprises the following steps: S1,roughening a beam surface; S2, binding a reinforcing mesh; S3, installing a side formwork; S4, performing concrete pouring, and performing mechanical automatic leveling; S5, carrying out mechanical automatic surface finishing and calendaring of the concrete; S6, carrying out maintenance and form removal; and S7, limiting the groove, and mechanically and automatically slotting the expansion joint.The construction process of limiting groove formwork installation and expansion joint formwork installation is omitted, so mechanical automatic construction of leveling, surface finishing and calendaring operation of base plate concrete is achieved.
本发明提供了一种高铁无砟轨道底座板施工方法。所述高铁无砟轨道底座板施工方法包括如下步骤：步骤S1、梁面凿毛；步骤S2、钢筋网片绑扎；步骤S3、侧模板安装；步骤S4、混凝土浇筑、机械自动化整平；步骤S5、混凝土机械自动化收面及压光；步骤S6、养护及拆模；步骤S7、限位凹槽、伸缩缝机械自动化开槽。本发明取消限位凹槽模板安装及伸缩缝模板安装的施工流程，从而使得底座板混凝土的整平、收面、压光作业实现了机械自动化施工。
