一种无砟轨道板充填层线上多功能作业装备
技术领域
本发明涉及一种无砟轨道板充填层线上多功能作业装备,能实现自密实混凝土自动搅拌灌注的作业装备,属于高速铁路施工技术领域。
背景技术
为了适应中国铁路“走出去”战略需要,必须提升中国无砟轨道技术的自主创新,打造中国无砟轨道的自身品牌。为此,在总结我国既有无砟轨道研究与应用经验的基础上,结合无砟轨道再创新研究成果,研发并铺设了具有完全自主知识产权的板式无砟轨道。
板式无砟轨道结构,采用自密实混凝土作为充填层材料,利用充填层自密实混凝土灌注工艺方法,将具有大的流动性、间隙通过性和抗离析性混凝土灌注至嵌有U形钢筋和钢筋网片的板腔中。自密实混凝土强度等级为C40,要求具有高流动度、不离析、填充均匀性和稳定性的性能,浇筑时依靠其自重流动,无需振捣而达到密实的混凝土,其自有收缩率应小于万分之三。在搅拌站制备后,通过罐车运输至线下,利用中转斗将自密实混凝土吊至线上灌注点实施灌注。但自密实混凝土在搅拌、运输、灌注过程中存在混凝土坍落度损失大,易离析、泌水等、包裹性差和浮浆等现象,灌注质量难以控制,造成了严重浪费。
发明内容
