Referring to the attached drawings 1 to 6 of the invention, an improved double-block sleeper according to an embodiment of the invention comprises connecting rods 1 and sleeper blocks 2 which are pairwise arranged oppositely in groups, wherein reinforcing frames 3 are arranged in the sleeper blocks 2 and are formed by pouring concrete, the connecting rods 1 are pairwise arranged horizontally in groups and are integrally formed between two adjacent sleeper blocks 2, and two ends of each connecting rod respectively extend out of the outer side walls of the corresponding sleeper blocks 2 one by one; the connecting rod 1 is a basalt fiber composite section.
Specifically, the basalt fiber composite section is formed by compounding basalt fibers and a resin matrix, the proportion of the basalt fibers, the resin matrix and an additive is 3:6:1, and the basalt fibers, the resin matrix and the additive are mixed, stirred and extruded to form the basalt fiber composite section. The tensile strength of the basalt fiber composite section is higher than that of a common steel bar, and the basalt fiber composite section can be restored to the original shape when large deformation occurs.
More specifically, the basalt fiber composite profile has main components including silica and iron oxide having good natural insulating properties.
The basalt fiber composite section has low degradation rate in acid, alkali, salt and moisture environments and has good durability. Ordinary steel bars are easy to corrode, and because corrosion causes cracks of the steel bars, the structural stability of the double-block sleeper is influenced.
The fatigue resistance of the basalt fiber composite section bar is equivalent to that of a steel bar, and the requirement of the double-block sleeper on the fatigue resistance can be met.
In other embodiments, the connecting rod 1 is a hollow round rod structure, and the connecting rod 1 is filled with a reinforcing material, and the specific reinforcing material may be self-compacting concrete.
The basalt fiber composite section bar has low elastic modulus, so the rigidity of the member is relatively low, the connecting rod 1 is of a hollow tube structure, corresponding reinforcing materials can be poured into the tube, and the rigidity and the stability of the connecting rod are improved.
Specifically, the inner diameter of the connecting rod 1 is 30mm, and the outer diameter is 50 mm.
In other embodiments, the outer surface of the tie rod 1 is provided with a plurality of ribs along its axial spacer ring, the spacing between which is 20mm, to improve the tightness of the connection with the tie blocks.
The invention also discloses a track plate, which comprises a track plate body and a plurality of double-block sleepers, wherein the track plate body is formed by pouring concrete, the double-block sleepers are arranged at intervals along the length direction and fixedly connected on the track plate body, the side wall of the connecting rod 1 is provided with a plurality of through connecting holes 5, fixing steel bars 4 are connected in the connecting holes 5, the fixing steel bars 4 are of a bent structure in a shape like a Chinese character 'men', two vertical sections of the fixing steel bars are respectively and correspondingly and fixedly connected in the connecting holes on the connecting rods adjacent to the two adjacent double-block sleepers, so that the double-block sleepers are conveniently connected and fixed, and the double-block sleepers are connected and fixed with the track plate body.
The invention also discloses a track system, wherein a plurality of track plate bodies are arranged in a length direction, and the rail is correspondingly arranged on the rail bearing surface of the rail pillow block in the plurality of double-block sleepers.
The connecting rod used in the invention is a basalt fiber composite profile, which is a high-performance composite material prepared by taking basalt fibers as main raw materials, and compared with common steel bars, the connecting rod has the characteristics of good insulating property, good corrosion resistance, high tensile strength, light weight and the like. The basalt fiber is used as the main component, and the basalt fiber contains 99% of basalt, belongs to naturally existing objects, does not generate toxic waste in the production process, has outstanding environmental protection performance compared with other fibers, and meets the requirement of environmental protection. And the service life of the basalt is hundreds of years or even thousands of years, the basalt can meet the design requirement of the same service life as the main structure of the ballastless track, and meanwhile, the basalt does not cause pollution to the environment.
The basalt fiber composite section is formed by compounding continuous basalt fibers (or high-strength fibers such as glass fibers) and a resin matrix material. The common resin matrix materials mainly comprise epoxy resin, vinyl ester resin, polyamide resin and the like, and the common auxiliary agents mainly comprise an initiator and an accelerant; the usual process is mainly pultrusion.
Furthermore, the acidity coefficient (SiO2+ Al2O3)/(CaO + MgO) of the basalt fiber is relatively large and is basically more than 5, so that the durability and the corrosion resistance are good, meanwhile, the corrosion resistance of the basalt fiber is influenced by FeO and Fe2O3 contained in the basalt fiber, and the K2O, MgO and TiO2 can improve the waterproof performance and the corrosion resistance, so that the durability of the double-block sleeper is improved. The volume specific resistance of the basalt fiber is higher than that of E-glass fiber and carbon fiber and is 1 multiplied by 1012 omega.m; the volume resistivity is higher than that of the electrically insulated E glass fiber by one order of magnitude, the dielectric loss angle is higher by 50 percent, and the insulativity of the double-block sleeper profile is further improved.
The specific gravity of the basalt fiber composite section is generally between 1.3 and 1.7 and is about 1/4-1/6 of steel. The self-weight of the structure can be effectively reduced, the transportation or the hoisting in site construction is easy, and the construction efficiency is improved.
Two-by-two connecting rods which are horizontally arranged in groups are connected with the sleeper blocks, so that the stability and symmetry of the structure are enhanced.
At present, continuous basalt fiber composite profiles are mostly formed by continuous extrusion, so that the hollow connecting rod with a circular structure is convenient to process. The tensile strength of the basalt fiber composite section is higher than that of a common steel bar, and the strength requirement of the double-block sleeper truss can be met by using a simpler structure.
Specifically, set up the reinforcement reinforcing bar of many equidirectionals between two adjacent sleepers on the track board, concrete door type muscle is tied up fixedly with the reinforcement reinforcing bar that connecting rod and track board bottom set up.
