specific Embodiment approach

[0039] Specific implementation methods, such as Figure 1-3 as shown,

[0040] A track alignment control method for a multi-track high-speed railway bridge: comprising the steps of:

[0041] A: Determine the construction sequence of railway lines: determine the construction period of each railway line of the multi-line railway;

[0042] B: foundation construction: build the girder body and bridge deck of the high-speed railway bridge, and pour the ballast bed 1 on the bridge deck and set the sleeper 2 on the ballast bed 1, the ballast bed 1 in this step is the ballast bed 1 of all railway lines, in this step The sleeper 2 is the sleeper 2 of all railway lines;

[0043] C: Construction of Annex 3: Arrange other Annex 3 at the design position except for the track and the components used to fix the track. The Annex 3 is a dead-load component located on the foundation in the railway line;

[0044] D: Laying of track 4: According to the construction period of the railway line de...

Embodiment approach

[0046] Further, as an implementation mode, the step A includes the following steps:

[0047] A1: Modeling and analysis of the degree of influence of the later laid track 4 on the line shape of the earlier laid track 4: establish a corresponding model, design different railway line construction sequences, and analyze the construction sequence of various railway lines, the latter laying of the earlier railway line The degree of influence of the track 4 alignment of the railway line;

[0048] A2: Determine the construction sequence: According to the degree of influence of each railway line determined in step A1, sort from high to low to obtain the laying sequence of each railway line.

[0049] In the above method, the multi-line high-speed railway bridge is modeled and analyzed, and then the construction sequence of each railway line is obtained. The track 4 of the railway line that has the greatest influence on the alignment of the laid track 4 is laid first, and the laid track ...

Abstract

The invention belongs to the technical field of bridge engineering and particularly relates to a rail linear control method for a multi-line high speed railway bridge. The method comprises the following steps of A, railway line construction sequence determining, B, foundation constructing, C, accessory construction and D, rail paving. According to the rail linear control method for the multi-line high speed railway bridge, specifically, all railway lines can be successively opened to traffic for the multi-line high speed railway bridge according to the traffic opening time sequence requirements of the step A, the railway line which is firstly opened to the traffic is put into use in advance, thus the condition that railways are put into use as soon as possible is ensured, and therefore economical performance in the railway construction process is ensured; and the linear influence of follow-up rail paving work on paved rails is also greatly reduced, and therefore the condition that all line rails have good line shapes is ensured.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a track alignment control method for multi-line high-speed railway bridges. Background technique [0002] With the rapid development of economy and society and the rapid progress of science and technology, the transportation industry has also made great progress. In the entire transportation industry, railway transportation is due to its high accuracy, strong continuity, large transportation volume, and low transportation costs. And other advantages, it has become an extremely important mode of transportation. [0003] In the current field of railway design and construction technology, the application of various new equipment and new construction methods has overcome traditional construction difficulties and further improved the construction level of railway lines. In order to meet higher transportation efficiency, two On the one hand, the design idea is t...
