The invention provides a method for detecting the irregularity of a temporary transportation track of an overlong TBM (
Tunnel Boring Machine)
tunnel under construction, which is applied to a track irregularity detection
evaluation system and aims to solve the problem of low detection capability of track irregularity detection in the prior art, and comprises the following steps of: (1) running a rail
train with a sensor on an initially paved temporary track according to different speeds; acquiring amplitudes of vehicles passing through track joints under different vehicle speed working conditions as initial values, and establishing a standard
database; (2) acquiring data such as speed, amplitude, mileage and the like during operation of the rail
train, comparing and analyzing the data with a standard
database, and evaluating the irregularity of each contact, each section of rail and each kilometer of rail; and (3) reminding a driver of vehicle deceleration through a vehicle-mounted
display device, and reminding a manager of temporary track maintenance through a
background data report. The method has the advantages that real-time detection and evaluation can be achieved through double-track measurement, manual inspection is reduced, the detection frequency is improved, and the temporary railway
vehicle driving risk is effectively reduced.
