The interface of the cast-in-place track slab concrete and the prefabricated double-block sleeper is the bonding position of new and old concrete, the bonding effect is not ideal due to field construction, and cracks easily appear on the bonding surface under the repeated action of high-frequency train impact load and the action of natural tension such as temperature and the like. The rainfall on the earth surface infiltrates into the initial cracks, so that the bonding strength among particles on the interface surface of the concrete material is reduced under the coupling action of train load and water, and loose and softened particles appear on the surface. When a train passes through the water-cooled water bearing device at a high speed, downward instantaneous pressure is applied to a sleeper, dynamic water pressure is generated by free water in cracks, and loose and softened particles on the surface of concrete are washed away at a certain pressure and flow rate while confined water is dissipated; after the train passes through, a short negative pressure suction force appears in the gap, the seeped free water is sucked back into the gap, and the concrete loose particles at the interface can be impacted in the process of water flow suck-back. After the scouring action on the interface by 'the extrusion of the flowing water flow during the passing of the train-the suck-back of the flowing water flow after the passing of the train' for a plurality of times, loose concrete particles on the interface are scoured off and brought out of a track structure, and cracks become more severe and gradually develop to the bottom of the sleeper, so that the sleeper is separated from a track plate and is suspended in an empty way.
