Abstract
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
The invention belongs to technical field of railway.
Background technology
No matter be existing line transformation or newly-built circuit, the circuit that motor-car travels is all generally have tiny fragments of stone, coal, etc. railway for master, but EMUs speed per hour reaches after 250 kilometers, the car abdomen tailstock can form strong cyclonic wind, blinding can be started, cause considerable risk to train operation, thus rail is directly layered on strong concrete plate.This is a much progress, but the main blinding that just solves can be started the presentation come, and still maintains concrete crosstie original state.Be not completely free of the impact of concrete crosstie on train yet.
Concrete slab below existing rail still remains the part that concrete crosstie is very long, between adjacent buttress block, plate face is level and smooth in addition, takes up the buttress block collided under rail with progressive hurricane with train and oppositely rolls, thus seriously block train operation during train operation.
Summary of the invention
The present invention is directed to above-mentioned defect, for filling below rail neutral gear between two buttress blocks, specially proposing the patch suitable with it.
The present invention guides backing plate, elastic layer and setscrew, pad etc. by steel concrete patch, stainless steel and forms.
Described steel concrete patch and rail both sides are equipped with one group of vertical setscrew through hole respectively, patch and the strong concrete plate pressed close to and pile up neatly between block and be provided with rubber and so on elastic layer, are provided with stainless steel guiding backing plate between elastic layer and patch.After elastic layer, guiding backing plate and patch put in place successively, be connected on railway concrete slab by setscrew assembly, its elastic layer and both sides are piled up neatly block and are maintained an equal level.
Under described concrete patch, Middle face is prefabricated with and drops down water hole perpendicular to rail.
The present invention by patch and annex thereof by below rail between two buttress blocks neutral gear fill, large sharp water conservancy diversion, it is energy-conservation that resistance falls in large profit, and structure is simple and clear, and cost is extremely low.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
In figure 1 be patch, 2 for elastic layer, 3 for stainless steel guiding backing plate, 4 for setscrew through hole, 5 for rail, 6 be concrete straight sheet pile block.
Detailed description of the invention
The present invention guides backing plate 3, elastic layer 2 and setscrew, pad etc. by steel concrete patch 1, stainless steel and forms.
Described steel concrete patch 1 and rail 5 both sides are equipped with one group of vertical setscrew through hole 4 respectively, patch 1 and the strong concrete plate pressed close to and pile up neatly between block 6 and be provided with rubber and so on elastic layer 2, be provided with stainless steel and guide backing plate 3 between elastic layer 2 and patch 1.After elastic layer 2, guiding backing plate 3 and patch 1 put in place successively, be connected on railway concrete slab by setscrew assembly, its elastic layer 2 and both sides are piled up neatly block 6 and are maintained an equal level.
Described concrete patch 1 time Middle face is prefabricated with and drops down water hole perpendicular to rail.
Claims (3)
1. rapid transit railway patch, be made up of steel concrete patch, stainless steel guiding backing plate, elastic layer and setscrew, pad, it is characterized in that, if the neutral gear between the adjacent two buttress blocks on rapid transit railway concrete slab is filled with steel concrete patch and annex thereof.
2. rapid transit railway patch according to claim 1, is characterized in that, patch and the strong concrete plate pressed close to and pile up neatly between block and be provided with rubber and so on elastic layer.
