Problems solved by technology

[0008] The purpose of the present invention is to: in the construction process of the existing long sleeper buried ballastless track, it is necessary to assemble the rail row on site first, and then use the support bracket to position and adjust on site and pour it into the cast-in-place bed slab. In view of the problems of low efficiency, long construction period and high construction cost, we provide a rail row type long sleeper embedded ballastless track and its construction method, which can not only improve the construction efficiency of the sleeper, shorten the construction period and reduce the cost, but also improve Integrity of ballastless track

Embodiment 1

[0060] The present embodiment provides a long-row rail sleeper buried ballastless track, such as figure 1 and figure 2 Shown, comprises a base plate 6, and is provided in situ on the base channel deck plate 4, 6, the pouring channel 4 in the deck unit length between three sleepers embedded in a plurality of said sleeper 3, a plurality of sleeper track panel formed by the connection mechanism, the rail-row long sleeper buried ballastless track comprising a rail mounted on a further 1 to 3 and sleeper fastening system (not shown), fastening the rail system in a fixed on the rail. A plurality of connection mechanism using the sleepers 3 are connected integrally to form a track panel, unitary structure, to solve the track panel construction assembly and adjustment positioning site present in the prior art when the sleepers embedded in a cast channel 3 deck 4 inefficiencies, comprising a plurality of one-time installation sleeper sleeper track panel 3, since the relative position has b...

Embodiment 2

[0072] The present embodiment provides a construction method for long-row rail sleeper buried ballastless track, such as Figure 1-6 , In the construction of such long-row rail sleeper buried ballastless track in the embodiment of Example 1, the main construction comprises:

[0073] a, factory prefabricated concrete sleeper 3, 31 and truss reinforced sleepers 3 are assembled into rows rail sleeper;

[0074] B, according to the measurement data track work, pouring concrete base plate 6 and the retaining groove 61 at the construction site, after the completion of pouring conservation;

[0075] C, the elastic cushion 51 laid on the retaining groove 6, and the laying of the separating layer 2 and the stopper surface of the surface recess 61 of the base plate 6;

[0076] d, erection sleeper track panel, and adjust, after pouring the concrete track bed board formwork, pouring channel thereby forming deck 4 and the stopper boss 5, while the deck 4 and the channel stopper cast bosses 5 con...

Abstract

The invention relates to the technical field of rail transit, in particular to a track panel type long sleeper embedded ballastless track and a construction method thereof. The ballastless track comprises a base plate and a cast-in-place roadbed slab arranged on the base plate, and a plurality of sleepers are embedded in the cast-in-place roadbed slab within the unit length; a sleeper track panelis formed among the sleepers through connecting mechanisms, steel rails and fastener systems are installed on the sleepers, the sleepers are connected into a whole through truss reinforcing steel barsto form a track panel type whole structure, track panel assembling and adjusting positioning on site are avoided, and due to the fact that the relative positions of the sleepers are adjusted in advance, when the sleeper track panel is buried in a cast-in-place roadbed slab, a plurality of sleepers can be in place only by one-time adjustment, so that the installation efficiency of the sleepers isgreatly improved, the construction period can be shortened, the cost can be reduced, and meanwhile, the integrity and durability of the ballastless track are further enhanced by the connecting mechanism for forming the track panel type sleepers.

Description

Technical field [0001] The present invention relates to the field of rail transportation technology, particularly to a long-row rail sleeper buried ballastless track construction method thereof. Background technique [0002] Ballastless track has high smoothness, high stability, durability characteristics, has become the common Slab Track high-speed rail passenger line. Long sleeper buried ballastless track structure is one of the main non-ballasted track, long sleeper buried ballastless track is a new track structure to adapt to my country's railway high-speed driving, high-speed rail development needs of research and development, with strength, stability and other technical features. Long sleeper buried ballastless track rail and the fastening consists essentially of, sleepers, said bed plate and the base plate. Because of the long sleeper buried ballastless track in a short time to promote our country, therefore, the structure and construction technology of long sleeper buried...
