Seawater sea sand concrete pavement structure and construction method
The invention belongs to the technical field of road engineering, and provides a seawater sea sand concrete pavement in order to solve the problems of river sand shortage, road erosion, difficult transportation of natural river sand in coastal cities and ocean engineering and the like, the seawater sea sand concrete pavement is formed by laying a base layer and a surface layer, and the surface layer is an FRP (Fiber Reinforce Plastic) bar-seawater and sea sand concrete layer. According to the seawater sea sand concrete pavement structure provided by the invention, the FRP ribs are used for weaving the rib nets in the plates, the FRP rib dowel bars are arranged in the transverse joints between the plates, the FRP rib pull rods are arranged in the longitudinal joints between the plates, and the seawater sea sand concrete is cast in place, so that the integrity and the strength of the pavement structure are improved. The FRP ribs are used for overall pavement reinforcement, the durability of the pavement is greatly improved, the mechanical property is optimized, the pavement is poured through seawater and sea sand concrete, higher early strength is achieved, the construction progress can be accelerated, the undesalted sea sand is used, and the manufacturing cost of coastal engineering and ocean engineering is remarkably reduced.
本发明属于道路工程技术领域，为解决河砂短缺、道路受侵蚀、沿海城市及海洋工程的天然河砂运输困难等问题，提供了一种海水海砂混凝土路面，其由基层和面层铺设而成，其中所述基层为水泥稳定碎石层、级配碎石层、回填碎石组成，所述面层为FRP筋‑海水海砂混凝土层。本发明提供的海水海砂混凝土路面结构，利用FRP筋编制板内筋网、板间横缝设置FRP筋传力杆、板间纵缝设置FRP筋拉杆，并现浇海水海砂混凝土，提高了路面结构的整体性和强度。利用FRP筋进行整体路面配筋，路面耐久性能得到较大提高，力学性能也得到了优化，利用海水海砂混凝土浇筑路面，具有更高的早期强度，有利于加快施工进度，并且利用了未淡化海砂，显著降低了沿海工程及海洋工程的造价。
