Device for monitoring internal deformation and fine particle loss of track roadbed

Abstract

The invention discloses a device for monitoring internal deformation and fine particle loss of a track roadbed, and relates to the field of monitoring devices. The device for monitoring internal deformation and fine particle loss of the track roadbed comprises an internal damage monitoring device arranged in a roadbed railway ballast layer; the internal damage monitoring device is connected with aresistance acquisition instrument through a wire; and the resistance acquisition instrument is wirelessly connected with a resistance signal receiver. According to the device for monitoring the internal deformation and the fine particle loss of the track roadbed, real-time continuous monitoring of the deformation and the fine particle loss in a railway roadbed under a rail traffic load under a remote condition can be realized, the device is economical and convenient, the practical value is higher.

Description

technical field [0001] The invention relates to the technical field of monitoring equipment, in particular to a monitoring device for internal deformation and fine particle loss of a track subgrade. Background technique [0002] In recent years, with the rapid development of rail transportation, the speed of trains and axle loads are constantly increasing, which greatly increases the burden on the railway subgrade, which causes the deformation of the railway subgrade to exceed expectations, which not only affects the train's Normal driving during operation also increases the cost of roadbed reinforcement and maintenance in the later period. At the same time, with the seepage of rainwater, the fine particles in the roadbed are washed away, which greatly affects the stability of the roadbed under the load of rail traffic. Therefore, timely monitoring of the internal deformation of the railway subgrade and the loss rate of internal fine particles, and reinforcement when a cert...

AI Technical Summary

Problems solved by technology

Today's monitoring methods are mainly subgrade surface settlement monitoring, and there are few monitoring methods for internal deformation of the subgrade, and the existing monitoring methods have a certain hysteresis. There are few methods for monitoring the deformation of the filling soil in the subgrade and the monitoring of the internal stress transfer of the subgrade; , it is difficult to monitor the sudden increase of internal deformation of the subgrade, which will bring great safety hazards to the safe running of trains

However, there are almost no monitoring methods for the loss rate of fine particles inside the roadbed, which brings great hidden dangers to the safe running of trains.
