Prefabricated concrete pavement and construction method
The invention provides a prefabricated concrete pavement and a construction method. A prefabricated pier foundation and a pier top positioning plate are adopted to provide support for a platform sliding rail and a pavement side mold, and a platform sliding beam can provide support for a scraper supporting beam and a vibrating supporting beam. Oblique prestress tie bars are adopted. When a cast-in-place surface layer is poured, pouring vibration and surface scraping can be synchronously carried out. An inserting type vibrating rod and a plane vibrator are adopted to cooperatively conduct concrete vibrating construction. A jig frame vertical die is connected with a jig frame bottom plate through a vertical die rotating hinge. A ductile transition layer is arranged between a prefabricated panel and a pavement base layer. Hoisting construction of the prefabricated panel is conducted through combination of rigid suspenders and special-shaped supporting plates. Penetrating positioning ribs are arranged in a prestressed rib penetrating pipe, and the prefabricated panel can be accurately positioned through a position control body transverse support and a position control body vertical support. An anchoring groove sealing body is made of a micro-expansion concrete material. The difficulty of cast-in-place surface layer pouring and prefabricated panel hoisting and positioning construction can be reduced, and the stress performance of the pavement structure is improved.
本发明提供预制装配式混凝土路面及施工方法，采用预制墩基础及墩顶调位板为平台滑轨及路面侧模提供支撑，其平台滑梁可为刮板撑梁和振捣撑梁提供支撑；采用斜向预应力拉筋；现浇面层浇筑时，可同步进行浇筑振捣和表面刮平；采用插入式振捣棒与平面振捣器协同进行混凝土振捣施工；胎架立模与胎架底板通过立模转动铰连接；在预制面板与路面基层之间设置了延性过渡层；采用刚性吊杆与异形撑板组合进行预制面板吊装施工；在预应力筋穿设管内设置了穿设定位筋，并可通过控位体横撑和控位体竖撑对预制面板进行精确控位；锚固槽封闭体采用微膨胀混凝土材料。本发明可降低现浇面层浇筑和预制面板吊装定位施工的难度、改善路面结构的受力性能。
