Description
技术领域:
本发明涉及一种降低压路机对现浇混凝土挡块路缘石多次碾压造成不可修复性破坏的施工方法。
背景技术:
国内外道路基本以沥青砼路面道路为主,而对道路工程中路面砼路面工序需在路缘石施工完成后才能施工,但在沥青砼施工过程中需要对路缘石成品加以保护,常规的施工方法:
依托上述作业形式有以下弊端:
首先第一条直接摊铺、碾压至路缘石边缘部位,在摊铺过程中会对路缘石产生污染,后期需清理,另外在碾压过程中必定会大范围的对路缘石造成不可修复性破坏,后续需更换被破坏的路缘石,更换难度及造价相当大。国家大力提倡的“降本提效”方针是今后所有工程项目乃至所有行业必须遵守且也应该自发性努力推行的方向。显然,目前施工工艺不够完善,与国家大力提倡的“降本提效”方针相差甚远。
发明内容:
为克服现有技术的缺陷,本发明的目的在于提供一种降低压路机对现浇混凝土挡块路缘石多次碾压造成不可修复性破坏的施工方法,在沥青路面碾压时对路缘石起到保护作用。
本发明解决技术问题采用如下技术方案:
降低压路机对现浇混凝土挡块路缘石多次碾压造成不可修复性破坏的施工方法,其包括如下步骤:
1)、现场准备,路面基层整平压实养生,之后安装路缘石;
2)、安装混凝土挡块模板,并对其进行支撑使其达到浇筑条件,确定使砼顶面标高与沥青上面层底面标高一致;
3)、进行混凝土挡块的浇筑;
4)、浇筑完成后,进行混凝土养护使其达到标准强度;
5)、进行沥青砼中、下面层施工;
6)、再进行沥青砼上面层施工。
作为优选,进一步地,所述混凝土挡块模板设置于路缘石的内侧,混凝土挡块浇筑成型后沥青中下面层与路缘石具有间距。
作为优选,进一步地,所述现场准备的步骤中,包括测量放线步骤,测量放线过程中在路缘石的内侧预留15cm的宽度用于浇筑混凝土挡块。
作为优选,进一步地,在步骤3)中,混凝土浇筑时在混凝土出料口设置减速装置,确保挡块混凝土的浇筑质量并且不冲击到路缘石。
与已有技术相比,本发明的有益效果体现在:
本发明成果面对大规模公路、市政道路路网建设施工时,为减少对成品路缘石的损坏和后期的观感质量,“沥青砼上面层下现浇混凝土挡块减少压路机对路缘石多次碾压造成不可修复性破坏”工艺能大大减少压路机多次碾压对路缘石造成的破坏的后期更换产生的人工及材料费用。本发明能够有效提高施工效率,在大规模公路、市政路网施工过程中能够有效提高施工进度和减少工程成本。
本发明研究实施充分体现企业管理降本提效工作理念,充分发挥工程项目施工管理因地制宜优势,在保证工程质量的前提下优化施工生产管理,提升机械使用效率,缩短工序用时,降低工程成本,具有较大推广前景。

1)、现场准备,路面基层整平压实养生,之后安装路缘石;
2)、安装混凝土挡块模板,并对其进行支撑使其达到浇筑条件,确定使砼顶面标高与沥青上面层底面标高一致;
3)、进行混凝土挡块的浇筑;
