Roadbed monitoring device

Abstract

The embodiment of the invention provides a roadbed monitoring device, which comprises: a plurality of displacement sensors respectively arranged at each to-be-measured point of a surface layer and a substrate layer of a roadbed, the displacement sensors located on the surface layer of the roadbed are connected to form a surface layer measuring line, and the displacement sensors located on the substrate layer of the roadbed are connected to form a substrate layer measuring line; a substrate layer reference satellite coordinate sensor arranged above the first displacement sensor located on the substrate layer of the roadbed; a substrate layer checking satellite coordinate sensor arranged above the second displacement sensor located on the substrate layer of the roadbed; a surface layer reference satellite coordinate sensor arranged above the third displacement sensor positioned on the surface layer of the roadbed; a surface layer checking satellite coordinate sensor arranged above the fourth displacement sensor located on the surface layer of the roadbed; processing equipment electrically connected with each displacement sensor and each satellite coordinate sensor; a power supply device. According to the roadbed monitoring device provided by the embodiment of the invention, the roadbed settlement monitoring precision can be improved.

Description

technical field [0001] The present application relates to roadbed monitoring technology, in particular to a roadbed monitoring device. Background technique [0002] The roadbed is the foundation of railway facilities, and the stability of the roadbed determines whether the railway operation is safe. During the construction of railway facilities and the operation of the railway, it is necessary to monitor the subgrade. When the subsidence of the subgrade is detected, corresponding measures must be taken to avoid serious impact on the operation of the railway. [0003] At present, the monitoring of the subgrade usually adopts a plurality of differential pressure static levels distributed at various points of the subgrade to be measured, so as to monitor the settlement of the points to be measured. figure 1 It is a structural schematic diagram of the roadbed monitoring device used in the related art to monitor the roadbed. Such as figure 1 As shown, a static level 11 is prov...
