Problems solved by technology

However, the existing embedded rails are mainly cast-in-place construction, and prefabricated slab structures are also used. The rail bearing grooves are rectangular openings, which have weak constraints on the concrete on both sides of the rails. The grooves are deep, and it is very difficult to replace the rails. The development of embedded track technology is greatly restricted, so a new type of embedded track beam is proposed

Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present invention. The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial sources.

[0022] Example:

[0023] Such as Figure 1-Figure 4 As shown, a new type of embedded track beam, the track beam 1 is composed of a rail bearing groove 4 with a bottom slope of the rail, a detachable concrete baffle 2, a ...

Abstract

The invention discloses a novel embedded track beam which is composed of a track bearing groove with a track bottom slope, a detachable concrete baffle, a check block installation embedded nut and aninstallation adjustment embedded nut, and at least two pouring holes are formed in the track bearing groove and used for different installation modes. The steel rail is fixed in the groove by the novel embedded track beam, and thus the structure is novel, the construction speed is high, and the maintenance performance is good; meanwhile, traditional fasteners are omitted, economic cost is reduced,the novel embedded track beam detachable baffle and the track beam are prefabricated and separated, respective production becomes simple and easy, a splayed structure is formed between the baffles, steel rail constraint is firmer, and concrete on the two sides is easier to detach in the maintenance process.

Description

technical field [0001] The invention relates to the technical field of rail transit engineering, in particular to a novel embedded rail beam. Background technique [0002] With the continuous growth of the scale of economic development, a large amount of materials need to be transferred from other places, and people need to flow quickly. Rail transit has the characteristics of large carrying capacity, fast safety, etc., and it is also a sign of the degree of development of a city. Local governments also use rail transit construction as a driving force. important means of urban economy. [0003] Embedded track is a form of ballastless track structure, which has the advantages of stable structure, small maintenance workload, low noise, and seamless connection with urban traffic. However, the existing embedded rails are mainly cast-in-place construction, and prefabricated slab structures are also used. The rail bearing grooves are rectangular openings, which have weak constrai...
