Abstract
The invention relates to the technical field of road and bridge construction, and concretely discloses a shield prefabricated segment which can be used in tunnel construction. The main body of the shield prefabricated segment is poured by concrete and is arched as a whole. The shield prefabricated segment includes an inner surface and an outer surface. A convex platform is arranged on the inner surface. Reinforcement in the concrete used for pouring the shield prefabricated segment adopts a glass fiber reinforced polymer. Compared with conventional concrete reinforcement which adopts steel bars, the shield prefabricated segment adopts the glass fiber reinforced polymer as the reinforcement which has corrosion resistance, can prolong the whole life of the shield prefabricated segment, has high tensile strength which is about twice the load of ordinary steel bars of the same specification, and is light in weight which is only one quarter of the weight of the steel bars of the same specification. Therefore, shield prefabricated segment greatly reduces the labor intensity of workers, reduces the transportation cost, can be easily cut so as to avoid damages to cutting heads in the production process, and can save time and cost.
