Abstract
The utility model belongs to the technical field of railway pavement and discloses a ballast-free railway in order to solve the problem of pool stability of an existing high-speed railway under great impact force. The ballast-free railway comprises a concrete road base layer, an asphalt damping layer, a sleeper, a pair of steel rails, a pair of positioning portions and a pair of strengthening portions. The asphalt damping layer is paved on the concrete road base layer, the sleeper is evenly paved on the asphalt damping layer, the steel rails are fixed on the sleeper, one positioning portion and one strengthening portion are tightly sequentially arranged on each of two sides of the sleeper, the positioning portions are located on the upper surface of the asphalt damping layer, and the strengthening portions are respectively fixed on two sides of the concrete road base layer and the asphalt damping layer. A notch is formed in the middle of the bottom surface of the sleeper. The ballast-free railway is used as the high-speed railway.
Description
Technical field
The utility model relates to without tiny fragments of stone, coal, etc. railway, belongs to railway laying technology field.
Background technology
At present, railroad train constantly raises speed, these bullet trains in the process of moving due to the existence of resistance very easily road pavement cause damage, and then the safety of train driving is reduced, and can increase the maintenance work of railway.Therefore, high-speed train track is had higher requirement.
High-speed railway rail, due to the water conservancy diversion weak effect to resistance, makes railway have the potential safety hazard of being opened by shake now; Meanwhile, the setting of existing track, when facing large impact force, stability is poor.
Summary of the invention
The utility model is in order to solve existing high-speed railway rail when being subject to large impact force, and the problem of poor stability provides a kind of without tiny fragments of stone, coal, etc. railway.
Described in the utility model without tiny fragments of stone, coal, etc. railway, it comprises concrete road basic unit, and it also comprises pitch buffer layer, sleeper, a pair of rail, a pair of location division and a pair of reinforcing portion,
Described concrete road basic unit upper berth is provided with pitch buffer layer, on pitch buffer layer, evenly lay sleeper, on sleeper, fix a pair of rail, the both sides of sleeper closely arrange respectively a location division and a reinforcing portion successively, described a pair of position point is in pitch buffer layer upper surface, and a pair of reinforcing portion is fixed on the both sides of concrete road basic unit and pitch buffer layer;
The middle part of described sleeper bottom surface is provided with breach.
It also comprises positioning screw,
This positioning screw through behind the center and pitch buffer layer of sleeper, is fixed in concrete road basic unit successively.
Advantage of the present utility model: the water conservancy diversion without tiny fragments of stone, coal, etc. railway described in the utility model is effective, it can effectively reduce traditional railway when train resistance is large, and the generation of road pavement damage makes railway avoid being shaken out, and has improved the safety of train driving.Meanwhile, it is provided with location division and reinforcing portion in the both sides of sleeper, makes sleeper better be fixed on original position, makes the stability of railway better, and then effectively reduces the recruitment of safeguarding of railway, has saved spending.
Accompanying drawing explanation
Fig. 1 is the structural representation without tiny fragments of stone, coal, etc. railway described in the utility model.
The specific embodiment
The specific embodiment one: below in conjunction with Fig. 1, present embodiment is described, without tiny fragments of stone, coal, etc. railway, it comprises concrete road basic unit 1 described in present embodiment, and it also comprises pitch buffer layer 2, sleeper 3, a pair of rail 4, a pair of location division 5 and a pair of reinforcing portion 6,
In described concrete road basic unit 1, be equipped with pitch buffer layer 2, on pitch buffer layer 2, evenly lay sleeper 3, on sleeper 3, fix a pair of rail 4, the both sides of sleeper 3 closely arrange respectively a location division 5 and a reinforcing portion 6 successively, described a pair of location division 5 is positioned at pitch buffer layer 2 upper surfaces, and a pair of reinforcing portion 6 is fixed on the both sides of concrete road basic unit 1 and pitch buffer layer 2;
The middle part of described sleeper 3 bottom surfaces is provided with breach 3-1.
In present embodiment, pitch buffer layer 2 can also be rubber cushion layer.
The setting of sleeper 3 bottom surface breach 3-1, the lateral force that is conducive to sleeper 3 to bear is better delivered to pitch buffer layer 2, makes train operation safer.
The specific embodiment two: below in conjunction with Fig. 1, present embodiment is described, present embodiment is described further embodiment one, and present embodiment also comprises positioning screw 7,
This positioning screw 7 through behind the center and pitch buffer layer 2 of sleeper 3, is fixed in concrete road basic unit 1 successively.
Positioning screw 7 in present embodiment is conducive to better ensure the stability of railway, in the process of positioning screw 7 location, can be combined with cementing agent and be poured in the hole that in sleeper 3, pitch buffer layer 2 and concrete road basic unit 1, corresponding positioning screw 7 passes.
For effectively reducing the noise in train driving process, can adopt damping material to cover sleeper 3, damping material can adopt cement and pitch to mix.
