Description

Elastomeric boots and elastic pad assemblies for ballastless tracks and ballastless tracks

technical field

The invention relates to the technical field of ballastless tracks, in particular to an elastic boot and an elastic backing assembly for the ballastless track and the ballastless track.

Background technique

The structure of ballastless track is accepted by high-speed railways all over the world because of its high smoothness, high stability, high durability and high reliability. With the rapid development of my country's railway industry, my country's ballastless track construction and operation mileage has ranked first in the world, and has accumulated rich experience in the research and design, construction and operation of ballastless track structures. Among them, the ballastless track types adopted by high-speed railways mainly include CRTSⅠ, CRTSⅡ slab type, double-block type, CRTSⅢ slab type, long sleeper buried type and slab ballastless track in the turnout area, etc. At present, the track structure has basically matured and gradually formed. General reference map.

At present, ballast track structure is mostly used in passenger and freight collinear railways and heavy-haul railways at home and abroad. On the one hand, as the traffic volume of passenger and freight collinear railways and heavy-duty railway ballast tracks at home and abroad increases year by year, the number of damages to rails, welded joints and turnouts has increased significantly, the residual deformation of the ballast bed has increased, and the ballast bed has become pulverized and hardened. The increasing rigidity intensifies the damage of the train to the foundation under the track and the deterioration of the geometric state of the track, forming a vicious circle of track state degradation. On the other hand, with the increase of traffic density and loading capacity, track maintenance work is more frequent, but the rate of skylights is getting lower and lower on busy main line railways. The maintenance time is short, and it is difficult to repair the line disease in time. Especially in long tunnels, maintenance of ballasted track structures is more difficult. Therefore, it is recommended to use ballastless track structure in tunnels with passenger and freight collinear railways and heavy-haul railways with a length greater than 1 km. Domestically, theoretical calculations and analyzes have been carried out for commonly used ballastless track structures, and a comprehensive comparison and analysis has been carried out in combination with the characteristics of different track structures and the operating conditions of passenger and freight collinear railways and heavy-haul railways. It is considered that: (1) In general, under the premise that the lower foundation meets the laying conditions of ballastless track, all kinds of ballastless track structures can be applied to passenger-cargo railways by adjusting the type size, strengthening structural reinforcement, and improving material properties. And heavy haul railway bearing requirements. (2) Unit slab ballastless track structure: the adaptability of the cement-emulsified asphalt mortar under the track slab to the operating conditions of passenger-cargo railways and heavy-haul railways with large axle loads still needs to be studied, and the construction of the track structure in the tunnel should be considered. Convenience, professional maintenance and technical economy, the use of unit slab ballastless track structure in the tunnel has no advantages. (3) The elastic long-pillar ballastless track structure has been laid in a small amount of subway lines in my country, and it has only been laid on passenger transport and subway operating lines in foreign countries. It is mainly considered as a vibration-reducing structure for urban rail transit. Rubber boots are easily polluted by dust and difficult to maintain. (4) Both the double-block type and the long-pillar buried ballastless track are cast-in-place pillow-type integral ballast bed structures. The stress systems of the two are the same, and the comprehensive performance is good. They have certain application experience in my country's passenger and freight lines. , the current overall use status is good, but all the vibration damping performance is realized by the fastener system, which is difficult. In view of the urgent need for a ballastless track with good applicability, good durability, strong repairability, good construction performance, economical and reasonable performance, and certain vibration damping performance in my country's passenger and freight collinear railways and heavy-duty railway tunnels form.

When the ballastless track is in use, dust and moisture will enter between the ballast bed plate and the elastic support block assembly through the gap between the ballast bed plate and the elastic support block assembly, which will affect the elasticity and stability of the ballastless track.

The first block 211 of the support block is an inverted trapezoid with a large top and a small bottom, so that the support block 21 can be taken out during maintenance in the future. The length, height, width, weight and buried depth of the short sleeper in the ballast bed can be adjusted arbitrarily according to user needs. To adapt to the requirements of different forms of railway track structures for the strength of the sleeper and the stability of the track structure; the upper and lower parts of the support block 21 have convex edges to prevent water or other sundries from directly penetrating into rubber elastic boots; the sleeper passes through the embedded parts (pre-embedded parts) Buried iron seat, casing or other connection devices) are connected with the fastener system, which improves the lateral bearing capacity of the ballastless track structure; the rail bearing surface of the support block 21 can be adapted to different types of railways and set different slopes, and can adapt to different fasteners at the same time The system sets limit structures such as shoulders, or does not set any limit structure of rubber pads under the rails. The limit of the rubber pads under the rails is mainly provided by embedded iron seats or other connecting devices. The center line of the pre-embedded iron seat, sleeve or other connecting device on the sleeper can coincide with the center line of the short sleeper, or its center line deviates from the center line of the short sleeper to both sides (inside or outside) by about 0 ~ 100mm, further strengthening the short sleeper The anti-tipping ability; the support block 21 can meet the requirements of the ballastless track of the heavy-duty railway with an axle load of 30t and above in addition to ordinary railways, high-speed railways, subways and light rails, and is suitable for laying 60kg/ m, 68kg/m, 75kg/m or other light and heavy rails.

The elastic backing plate 23 adopts a microporous foam structure type. In the past, the elastic backing plate 23 in trunk railways usually adopts a common rubber backing plate structure, and grooves are provided on the upper and lower surfaces to provide elasticity. During operation, pollutants are easy to enter the grooves and affect the elasticity.

The elastic boots 22 wrap the support block 21 and the elastic backing plate 23, which is convenient for construction and maintenance, so that the support block 21 can be slightly displaced relative to the ballast bed slab 10; the lateral (horizontal and longitudinal) elasticity of the track is provided, so that the wheel-rail load can be Distributed over a long range in the longitudinal direction.

Support block 21, elastic backing plate 23, elastic boot 22 form elastic support block assembly, two rows of elastic support block assemblies are put into formwork, pour concrete to form track bed slab 10, track bed slab 10 and elastic support block assembly form an integrated structure.

After the track bed plate 10 is solidified and stable, a sealing strip is provided around the supporting block 21. The sealing strip is a material with certain elasticity and sealing function such as polysulfide material, silicone material or polyurethane material, and is in contact with the supporting block 21 and the track bed plate 10. The exposed part of the elastic boot 22 is sealed to prevent pollutants from entering the elastic boot 22 and affecting the elasticity of the elastic backing plate 23, thereby affecting the elastic performance and stability of the overall structure. A certain degree of elasticity of the sealing strip will not affect the lateral and longitudinal displacement of the support block 21 under a stressed state, and will not be easily damaged due to dynamic loads.

Within the range of 200m from the tunnel entrance, the track bed slab 10 is poured in blocks, and the track bed slab 10 is poured vertically and continuously outside the range of 200m from the tunnel entrance. In case of deformation joints in the tunnel structure, the track bed slab 10 is correspondingly provided with a 20 mm wide transverse expansion joint, and the center of the expansion joint is aligned with the center of the deformation joint. Properly adjust the node spacing of the fastener before and after the expansion joint so that the expansion joint is located in the middle of the spacing of the elastic support block assembly 20 (composed of the support block 21, the elastic boot 22, and the elastic backing plate 23, the same below), and the adjustment range of the node spacing of the fastener is 575-650mm . Filled with polyethylene foam board, the upper layer is poured with resin waterproof caulking glue. The sub-block track bed slab within 200m from the tunnel entrance is connected with the tunnel inverted arch backfill layer or the structural floor through pre-embedded steel bars. A row of pre-embedded steel bars is arranged within the interval of each elastic support block assembly 20, and each row is 4, located in the middle of the interval of the elastic support block assembly 20. The pre-embedded reinforcement adopts an "L" shape, with a total height of 400mm, of which the length of the implanted lower tunnel structure is 200mm, and the length of the exposed straight section is 100mm. Continually pour the invert backfill layer at the end of the track bed slab before and after the expansion joint of the track bed greater than 200m from the tunnel entrance or implant eight rows of threaded steel bars into the structural bottom plate, four in each row, located in the middle of the elastic support block assembly 20 . The track bed slab 10 is connected with the substructure to form an integrated structure by implanting steel bars, so as to enhance the integrity and stability of the track system.

The track bed slab 10 is equipped with ordinary steel bars, and the steel bars can adopt measures such as resin steel bars or insulating coatings, insulating cards, etc., to meet the technical requirements of track circuit insulation. As an alternative and particularly advantageous form, a prestressed structure combining ordinary steel bars and prestressed steel bars can be used to effectively prevent cracks in the track slab.

The elastic bearing block assembly type ballastless track system of the present application also has good adaptability to curves and vertical curves. The two rows of elastic support block assemblies arranged above the track slab can be adjusted vertically or horizontally during the manufacturing process of the track bed slab 10, which will be very beneficial to the adaptability of the track system in different track directions.

In a preferred embodiment, for curved sections, two rows of elastic support block assemblies 20 can be arranged symmetrically along the curve, at this time, the distance between each elastic support block assembly in one row of elastic support block assemblies 20 is greater than that of the other row The spacing between each elastic support block assembly in the elastic support block assembly reduces the number of elastic support block assemblies 20 on the premise of not affecting the running stability of the track, thereby saving cost.

When the track bed slab 10 is manufactured, according to the setting requirements of the superelevation of the curve, the heights of the two rows of elastic support block assemblies 20 and 20 arranged on the top surface of the track slab are adjusted to realize the superelevation change of the curved section and the adjustment of the track direction, and can reduce the The workload of track fine-tuning in the later stage.

Of course, as those skilled in the art know, the gauge between one row of elastic support block assemblies 20 and another row of elastic support block assemblies 20 is variable. In this way, it can adapt to the use of part of the gauge widening section.

From the above description, it can be seen that the above-mentioned embodiments of the present invention have achieved the following technical effects:
