Problems solved by technology

Tram projects are generally built in the city area, and there are many level crossings. The construction of traditional level crossings takes a long time from the completion of the construction of the subgrade support layer to complete the subsequent track construction. People's transportation has a great impact

Embodiment 1

[0039] see figure 1 , the present embodiment proposes a rapid construction method for a level crossing track, which specifically includes the following steps:

[0040] S1. Prefabricated track integrated unit and crossing plate, wherein the crossing plate is formed with mortar pouring holes;

[0041] S2, at the construction site, carry out the subgrade support layer construction;

[0042] S3. Transport the prefabricated track integrated unit and crossing plate to the construction site, and lay the prefabricated track integrated unit and crossing plate on the subgrade support layer;

[0043] S4, pouring and forming a mortar adjustment layer at the bottom of the prefabricated track integration unit and the crossing plate through the mortar pouring hole;

[0044] S5. After the mortar adjustment layer is cured, a road pavement layer is laid on the top of the track slab dust collection unit and the crossing slab.

[0045] In this embodiment, prefabricated track integrated units a...

Embodiment 2

[0057] See figure 2 and image 3 , Embodiment 2 is roughly the same as Embodiment 1, but the construction objects targeted by the two are different. The construction object targeted by this embodiment is a two-way embedded track, which includes two lines, and crossing plates are laid between the two lines and on the outside of the two lines.

Embodiment 3

[0059] See Figure 4 and Figure 5 , Embodiment 3 is substantially the same as Embodiment 1, but in Embodiment 3, the prefabricated track integration unit includes: a prefabricated track slab and a rail assembly, the rail assembly includes fasteners and rails, and the rails are connected by fasteners Fixed on top of prefabricated track slabs.

Abstract

The invention discloses a rapid construction method for a level crossing rail, relates to the technical field of rail construction methods, and mainly adopts a prefabricated rail integration unit anda crossing plate to form most of rail structures in advance. In the construction site, implementation personnel only need to correspondingly construct the roadbed supporting layer, the mortar adjusting layer and the pavement paving layer, the cast-in-place amount of the whole construction site is reduced, and therefore the construction speed of a project is increased.

Description

technical field [0001] The invention relates to the technical field of track construction methods, in particular to a rapid track construction method at level crossings. Background technique [0002] In recent years, with the increasing development of the rail transit industry, modern trams have become an important component of urban rail transit by virtue of their advantages such as energy saving, environmental protection, low noise, and large passenger capacity. trend. Tram projects are generally built in the city area, and there are many level crossings. The construction of traditional level crossings takes a long time from the completion of the construction of the subgrade support layer to complete the subsequent part of the track construction. People's traffic travel has brought a greater impact. Therefore, how to accelerate the construction rate of the level crossing track becomes a technical problem to be solved urgently. Contents of the invention [0003] The in...
