Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] This embodiment discloses an overhead construction structure for existing railway basement disease rectification lines, such as Figure 1-3 As shown, taking the application in tunnel construction as an example, it includes a main beam 1 for supporting rails, and the two ends of the main beam 1 are fixed. The main beam is made of H-shaped steel, with a size of 290mm×200mm×8mm×12mm.

[0033] Specifically, as Figure 1-3 As shown, this embodiment also includes a fixed support pier 2 , and the two ends of the beam 1 are arranged above the support pier 2 . The buttresses 2 are made by vertical...

Abstract

The invention discloses a construction structure enabling a line to be overhead during existing railway foundation base disease treatment. The construction structure comprises a main cross beam used for supporting a steel rail, wherein the two ends of the main cross beam are fixed. The invention also discloses a construction method based on the construction structure. The construction method comprises the following steps: firstly, removing a steel rail; secondly, mounting a main cross beam and a secondary cross beam; thirdly, erecting a longitudinal beam; fourthly, mounting the steel rail; andfifthly, carrying out base changing construction. The invention aims at solving the problem that an existing railway foundation base disease treatment construction technology can not carry out construction without interrupting a running train and provides the construction structure enabling the line to be overhead during the existing railway foundation base disease treatment and the constructionmethod. The construction structure and the construction method have the advantages that a railway line is overhead, and thorough foundation base disease treatment can be carried out while normal running of a business line can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of railway construction, and in particular relates to an overhead construction structure of an existing railway basement disease rectification line and a construction method based on the construction structure. Background technique [0002] The design standards of the existing railways currently in operation in my country are relatively low. In recent years, due to various reasons such as railway speed increase, high traffic density, heavy-duty trains, long-term fatigue damage, winter freeze-thaw damage, and excessive groundwater pressure, etc., Damage to substrates in operation is more severe. There are more and more defects and diseases of different degrees, such as cracking, slurrying, and arching deformation of the bottom plate, which affect the stability of the line and endanger the safety of driving. The existing construction technology can only stop the operation of the railway line first, and then ca...
