Still not completely free from the impact of concrete sleepers on trains
[0003] A long part of the concrete sleeper still remains on the concrete slab below the rails, and the slabs between adjacent stacks are smooth. When the train is running, the hurricane that moves in the same direction as the train hits the stacks under the rails and rolls up in reverse. , thus seriously hindering the train operation

Embodiment Construction
[0012] The invention is composed of a reinforced concrete patch 1, a stainless steel guide plate 3, an elastic cushion 2, expansion screws, gaskets and the like.
[0013] A group of vertical expansion screw through holes 4 are respectively arranged on both sides of the reinforced concrete patch 1 and the rail 5, and an elastic cushion such as rubber is arranged between the patch 1 and the adjacent high-strength concrete slab and its stacking block 6 2. There is a stainless steel guide plate 3 between the elastic cushion layer 2 and the patch 1. After the elastic cushion 2, the guide backing plate 3 and the patch 1 are put in place in sequence, they are fixedly connected to the railway concrete slab through the expansion screw assembly, and the elastic cushion 2 is flat with the stacking blocks 6 on both sides.
[0014] The lower middle part of the concrete patch 1 is prefabricated with water dripping holes perpendicular to the rail.

The invention relates to a high-speed railway patch. The high-speed railway patch comprises a reinforced concrete patch, a stainless steel guide backing plate, an elastic cushion layer, expansion screws and gaskets, wherein the reinforced concrete patch and accessories of the reinforced concrete patch are arranged to fill empty space between two adjacent pile blocks on a high-speed railway concrete plate. According to the high-speed railway patch, the empty space between two adjacent pile blocks below steel rails through the patch and the accessories of the patch, flow guidance is greatly facilitated, resistance reduction and energy conservation are greatly facilitated, the structure is concise, and the cost is very low.
Description
technical field [0001] The invention belongs to the technical field of railway construction. Background technique [0002] Regardless of whether it is an existing line reconstruction or a new line, the lines that EMUs run are generally ballasted railways. However, after the speed of the EMUs reaches 250 kilometers per hour, a strong cyclone will be formed at the rear of the car, and the gravel will fall. It was lifted up, which caused great danger to the train operation, so the steel rails were directly laid on the high-strength concrete slab. This is a big improvement, but mainly it only solves the appearance that the gravel will be lifted up, and the original shape of the concrete pillow is still preserved. The impact of concrete sleepers on trains has not been completely eliminated. [0003] A long part of the concrete sleeper still remains on the concrete slab below the rails, and the slabs between adjacent stacks are smooth. When the train is running, the hurricane th...
