Reinforced concrete surface layer construction process
The invention provides a reinforced concrete surface layer construction process which comprises the following steps: firstly, preparing a lower bearing layer, determining sample piles such as a road surface center, a road surface width and vertical and horizontal elevations according to a design file, a retest plane and an elevation control pile, then erecting a template and placing a reinforcing steel bar frame, then pouring stirred concrete into the template, and before pouring, pouring the concrete into the template; the height, lubrication and supporting stability conditions of a formwork, the flatness and lubrication conditions of a base layer and the placement position of a steel bar frame are comprehensively checked, then trimming, seam sawing and grooving are conducted on a concrete slab, and when the concrete slab reaches the design strength, traffic can be opened. Compared with a traditional technical scheme, the process has the advantages that the double-layer and integrated steel bar frame is adopted as an inner support of the reinforced concrete surface layer, so that the steel bar frame does not move or deviate, and the thickness of the concrete protection layer specified by the construction specification is achieved, and when corner steel bars and force transmission steel bars are arranged and the steel bar surface layer is laid in the construction process, the construction efficiency is greatly improved. The method is convenient and high in efficiency.
本发明提供了一种钢筋混凝土面层施工工艺，首先准备下承层，根据设计文件，复测平面和高程控制桩，据此以定出路面中心、路面宽度和纵横高程等样桩，然后架设模板并放置钢筋框架，随后将搅拌好的混凝土浇筑进模板，在浇筑前，对模板高度、润滑、支撑稳定情况和基层平整、润滑情况，以及钢筋框架的放置位置进行全面检查，随后对混凝土板修整、锯缝以及刻槽，当混凝土板达到设计强度时，可以开放交通。相较于传统技术方案，本工艺采用双层且一体的钢筋框架作为钢筋混凝土面层的内支撑，钢筋框架也就没有移动以及偏移的风险，使其达到施工规范所规定的混凝土保护层厚度，在施工过程中布置角隅钢筋、传力钢筋以及铺设钢筋面层时，也较为便捷，效率高。
