Failure renovation method suitable for sleeper-free ballast bed directly-buried base plate

Abstract

The invention discloses a failure renovation method suitable for a sleeper-free ballast bed direct-buried base plate, which belongs to the field of ballast bed disease renovation, and comprises the following steps of: measuring a track parameter of a disease position of the sleeper-free ballast bed direct-buried base plate, and comparing the track parameter with an initial design parameter of a line to correspondingly generate a parameter statistical table of failure renovation; and the thin sleepers of the corresponding models are selected according to the standard, and failure improvement of the sleeper-free track bed direct-buried base plate is achieved through the solution that the thin sleepers are locally added for transition. The failure renovation method suitable for the sleeper-free ballast bed direct-buried base plate is simple in step, simple and convenient in operation process, capable of effectively achieving disease renovation of the sleeper-free ballast bed direct-buried base plate and improving the setting stability of the sleeper-free ballast bed direct-buried base plate, and the renovation scheme designed through the thin sleeper is high in flexibility, high in compatibility and high in practicability. The method can meet the treatment of different field conditions, shortens the period of failure treatment of the directly-buried backing plate, reduces the cost of failure treatment, and has a better application prospect and popularization value.

Description

technical field [0001] The invention belongs to the field of disease treatment of ballast beds, and in particular relates to a failure treatment method suitable for directly buried backing plates of pillowless ballast beds. Background technique [0002] With the continuous development of my country's rail transit industry, the design forms of rail transit structures are becoming more and more diverse, including rail transit forms that use pillowless integral ballast beds to set up track structures. [0003] Among the pillowless monolithic track beds, the most widely used product is the steel spring floating slab track bed, which has good vibration and noise reduction effects, and is therefore widely used in urban rail transit. However, due to the particularity and complexity of urban rail transit, after a period of operation and use of the steel spring floating slab track bed, some problems and deficiencies will inevitably occur, resulting in the failure of the pillowless in...

Problems solved by technology

Such methods are not only costly, time-consuming, and expensive, but also difficult to construct and have a long construction period. However, the skylight points of urban rail transit are generally short, making it difficult for existing methods to meet the renovation needs of existing lines.
