Abstract

The invention provides a ballast track subgrade settlement monitoring device and a ballast track subgrade settlement monitoring method applying the same. The monitoring device comprises a mounting bottom plate, a settlement marker post and a protective sleeve, the mounting bottom plate is arranged on a ballast track roadbed, roadbed settlement is transmitted to the settlement marker post through the mounting bottom plate, and roadbed settlement is reflected through displacement of the top of the settlement marker post; and the protective sleeve sleeves the settlement marker post to prevent inaccurate measurement caused by extrusion of the railway ballast on the settlement marker post. Particularly, the mounting bottom plate can deform and has a folded state and an unfolded state before andafter deformation, the overall size of the mounting bottom plate is small when the mounting bottom plate is in the folded state, and the mounting bottom plate can smoothly penetrate through small gaps between ballast track sleepers and move to a roadbed.

Description

Technical field [0001] The invention relates to the technical field of rail transit safety monitoring, in particular to a ballasted track roadbed settlement monitoring device and a ballasted track roadbed settlement monitoring method. Background technique [0002] The settlement monitoring of the existing ballast track subgrade is an important means to understand the working performance of the railway subgrade in service. The settlement monitoring of the existing ballast track subgrade is difficult to implement due to the obstruction of the track structure (including rails, sleepers, fasteners and ballast, etc.) above the subgrade surface. Therefore, the settlement monitoring of the existing ballast track subgrade mainly monitors the settlement of the road shoulder, which is still quite different from the settlement of the directly loaded subgrade surface. The settling plates currently used for roadbed settlement monitoring are mainly used for newly built roadbeds, and their bot...
