Abstract

The invention discloses a fabricated type reactive powder concrete prefabricated pavement slab without a reinforcing rib and a manufacturing method thereof. A slab body is a material plate made from reactive powder concrete; layers of horizontal steel wire gauzes are respectively spread in the reactive powder concrete material plate and are close to upper and lower surfaces; hoisting embedded parts which run through in the vertical direction are respectively arranged at the four corners, wherein the two ends of the hoisting embedded parts are connected with lifting appliances. When the fabricated type reactive powder concrete prefabricated pavement slab without the reinforcing rib is manufactured, the fluidity of the reactive powder concrete is controlled to avoid deformation of the pavement slab in the later-period manufacturing process, and the fabricated type reactive powder concrete prefabricated pavement slab without the reinforcing rib is maintained naturally indoors to ensure the total quality of the pavement slab. Compared with a common concrete pavement slab, the pavement slab has the advantages of no reinforcing rib in structure, small thickness, portability, light weight, convenience in transportation and installation, high intensity, wear resistance, high bearing capability, good anti-impact performance, good anti-fatigue performance, good weather resistance, and fast and efficient construction, repeated use, and can be widely applied to road construction of temporary building living quarters.

Description

technical field

[0001] The invention relates to the technical field of road surface construction, in particular to a high-strength active powder concrete prefabricated road slab and a manufacturing method thereof. Background technique

[0002] Reactive Powder Concrete, or RPC for short, is a new type of cement-based composite material. This material was first invented by the French Bouygues company in the 1990s. It was produced through specific methods and conditions. It has ultra-high strength and excellent durability. It has broad application prospects in petroleum, nuclear power, municipal, marine and military facilities and other projects. Foreign application projects mainly include Sherbrooke in Quebec, Canada, the world's first prestressed active powder concrete structure pedestrian bridge, Cattenom nuclear power plant in France, an arched pedestrian bridge in Seoul, South Korea, etc. In my country, it is mainly used in high-speed rail passenger dedicated line sidewalk...
