Problems solved by technology

However, the support brackets in the prior art can only limit the inclined braces of the rail adjustment brackets in a construction environment with convenient support. The increased height, hereinafter referred to as the heightened section of the ballast bed structure) and the section of the bridge deck without concrete retaining walls cannot provide a good point for the rail adjustment braces, so special braces need to be processed to ensure accurate adjustment and stabilize the geometric state of the track
In either case, it will eventually lead to delays in the construction period and increased costs

Embodiment 1

[0018] Embodiment 1 Take the elevated section as an example, the elevated section lacks the force points of diagonal braces. Therefore, when setting up the construction of the rail adjustment bracket, if figure 1 As shown, brace brackets are set on both sides of the rail row. Refer to the structure of the braced bracket figure 2 and image 3 , which includes: a bracket bottom plate, a vertical support and an oblique reinforcement plate. The bottom plate of the bracket is made of 12# national standard channel steel with a length of 350mm. There are multiple bolt holes at the bottom, and the bolt holes are distributed on the front and rear sides of the bottom plate of the bracket (corresponding to image 3 The right side and the left side in the middle), are respectively 25mm, 270mm and 330mm away from the rear end, and the diameter of the bolt hole is 16mm in the present embodiment. The vertical support adopts 10# national standard channel steel, and the vertical support a...

Embodiment 2

[0019] Embodiment 2 takes the bridge deck without concrete retaining wall as an example. Such as Figure 4 As shown, also set the diagonal brackets on both sides of the rail row. The structure of the brace bracket is the same as in Embodiment 1.

[0020] In Embodiment 1 and Embodiment 2, the rail adjustment brackets can all adopt the down-loading type rail adjustment brackets, and the rail adjustment brackets can be rationally distributed according to the quality of the steel rail and the support block per unit length and the bearing capacity of the support frame. Straight line 3m, curve 2.5m spacing layout, the layout of the support frame at the rail joint can be adjusted appropriately, the existing general section is used for rail adjustment support, the force point of the diagonal brace is set on the support bracket, and the overall ballast bed construction process is the same as that of the general section .

[0021] The diagonal brace bracket is fixed on the structural...

Abstract

The invention relates to a construction method of a monolithic track bed of a track. The method comprises the step of arranging a track adjusting bracket including a track adjusting inclined strut, and is characterized in that an inclined strut bracket is arranged on one side or inclined strut brackets are arranged at two sides of a track panel. One end of the track adjusting inclined strut is propped against the inclined strut bracket, and the other end of the track adjusting inclined strut is supported on a steel rail web to form a track adjusting support system with a single section with the track adjusting bracket. The monolithic track bed construction method can be used in cooperation with an existing track adjusting supporting system, and the existing common track adjusting supporting system can be applied to elevated line track structure heightened sections or elevated line special sections without concrete retaining walls and without supporting acting points. By means of the method, the requirement of the inclined strut for the supporting face of the construction site is reduced to a large extent, and larger precise rail adjusting space positioning is further obtained.

Description

technical field [0001] The invention relates to a method for assisting in laying a track, in particular to a construction method for an integral track bed. Background technique [0002] The track laying project is a key link in the construction of rail transit projects. The completion of the track laying node will directly affect the process of system engineering and electromechanical installation, and then affect the opening period of the whole line. Effective use of convenient machinery and tools can greatly guarantee the improvement of engineering construction efficiency. [0003] At present, more and more track adjustment brackets are put into the construction of subway track laying. The track adjustment bracket is a tool used to fix the track, adjust the gauge and adjust the elevation of the track when laying the integral track bed. It can be applied to the situation where artificial loose sleepers and short sleepers are required in the construction of intercity railwa...
