Fiber-reinforced prestressed reinforced concrete sleeper
Disclosed is a fiber-reinforced prestressed reinforced concrete sleeper. The sleeper is integrally pouring molded and comprises: a sleeper body (3) and rail bearing areas (2), wherein steel rail clamping seats are arranged on the surfaces of the rail bearing areas (2), and there are two rail bearing areas (2) respectively located under a steel rail on two sides of the sleeper and located above the sleeper body (3). A fiber-reinforced material is only added into the rail bearing areas (2), reinforcement ribs are configured in the sleeper body (3) and the fiber-reinforced material is mainly disposed in a main stressed area under a steel rail bearing face. The fiber material is designed to be added into a specific area during the production of a concrete sleeper, thereby improving the wear-resistant property and the crack-resistant property of concrete, being well-adapted to a stressed condition of the sleeper, so that the service life of the concrete sleeper is increased and the stability of running of a railway is improved.
