In addition, when rolling stock goes on curve, by the radial load of radial direction acceleration generation, i.e. centrifugal force.Because radius is more little, centrifugal force is big more; And the lateral force that the rolling stock that centrifugal force is bigger, track receives operation is transmitted is just big more, and is also big more naturally to the destruction of track.Like this, not only increase the physical labor intensity of field worker in construction, and caused heavy haul railway transportation production to have serious potential safety hazard.
Summary of the invention
The purpose of the utility model is to overcome the little difficult construction of non-fragment orbit radius in the above-mentioned prior art; And bear the shortcoming of centrifugal force difference; And a kind of no tiny fragments of stone, coal, etc. curve track is provided, through selecting the track plate of respective numbers for use, can connect into the track of required orbit radius easily.
Realize that the technical scheme that the utility model purpose adopts is: a kind of no tiny fragments of stone, coal, etc. curve track, comprise sole-plate and the rail that is installed in the sole-plate upper surface at least, said sole-plate closely is formed by connecting through waist some track plates that are isosceles trapezoid successively.
Further, said track intralamellar part is provided with horizontal direction and the cross one another structure muscle of vertical direction, and the structure muscle of said vertical direction stretches out the soffit of track plate, and is connected as a single entity through cementitious material and ground pedestal.
Further, the structure muscle of said vertical direction connects through the power muscle at the external part direction along ng a path of track plate soffit.
Further, said rail is installed in the upper surface of sole-plate through fastener.
The sole-plate of the utility model is is closely connected and composed through waist by some track plates that are isosceles trapezoid successively; When the quantity of used track plate many more; The broken line that its inner side edge connects into more is tending towards being inscribed within a circle, thereby is connected to form a curve track by a plurality of track plates.Therefore, the utility model is particularly useful for the railway of sharp radius curve.
The utility model is simple in structure, and construction is simple.In addition, because interior employing level of track plate and the cross-coupled structure muscle of vertical direction, thereby bear the lateral force that the rolling stock operation is transmitted effectively, slow down the destruction of lateral force to track.
