Embodiment

[0013] refer to Figure 1-Figure 3 , a specific embodiment of the flexible wrapping structure of the tram track of the present invention includes a grooved rail 1, the bottom of the grooved rail 1 is provided with a rail bottom sheath 2, and both sides of the grooved rail 1 are provided with rail waist flexible materials .

[0014] The rail waist flexible material is a double-block structure composed of a "┓┏"-shaped inner layer of flexible material 3 and an outer layer of flexible material 4 .

[0015] The inner layer of flexible material 3 is glued on both sides of the rail waist of the grooved rail 1 .

[0016] The outer layer flexible material 4 is clamped at the groove of the inner layer flexible material 3 .

[0017] like image 3 As shown, the inner layer flexible material 3 and the outer layer flexible material 4 are connected in a staggered connection manner.

[0018] The inner layer of flexible material 3 is a solid material, the outer layer of flexible material ...

Abstract

The invention relates to the technical field of novel rails of tramcars, in particular to a tramcar rail flexible coating structure. The structure comprises a groove-shaped rail, the bottom of the groove-shaped rail is provided with a rail flange protective sleeve, the waists of two sides of the groove-shaped rail are provided with a rail waist flexible material, an adhesion agent is arranged between the groove-shaped rail and the rail waist flexible material to adhere the groove-shaped rail with the rail waist flexible material, the rail waist flexible material is internally provided with a cavity, the cross-sectional area of the cavity is less than or equal to 25% of the cross-sectional area of the rail waist flexible material, the rail waist flexible material is provided with a rail topsealant, and the top face of the rail top sealant is lower than the top face of the groove-shaped rail. The tramcar rail flexible coating structure has the advantages that from the perspective of theinsulating property, pressure resistance and airtightness, targeted novel designs are carried out in terms of cross section, longitudinal connection and performance index of a flexible coating system, the cross section design of the rail waist flexible material improves the location of an internal cavity of the coating structure, the insulating property and the waterproofness are improved, the inner layer and the outer layer are in break joint connection, so that the airtightness of the system is improved.

Description

technical field [0001] The invention relates to the technical field of novel tracks for modern trams, in particular to a flexible wrapping structure of tram tracks. Background technique [0002] The tram basically walks on the urban road, the track structure is embedded, and the surface is covered with greening, asphalt concrete, brick and other pavements. The flexible wrapping system is an important part of the tramway structure, which can reduce the vibration and noise caused by the operation of tramcars. , but also to improve passenger comfort. However, from the perspective of existing projects, due to the unreasonable structural type of the flexible wrapping system, the asphalt pavement and wrapping materials are prone to cracking, resulting in problems such as poor sealing and insulation of the rail. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned defects of the prior art, the technical purpose of the present invention is to provide a flexible wrapp...
