A monitoring system and method for subgrade settlement

Abstract

The invention discloses a monitoring system and method of subgrade settlement. The monitoring system is characterized by comprising the monitoring system comprises reference pegs arranged on base rocks of the two ends of a section of subgrade, several settlement pegs are arranged at the portion, between two reference pegs, of the subgrade at equal intervals, a guide rail is erected on the reference pegs and the settlement pegs through several supporting rods, and a position marker is arranged at the portion, opposite to each settlement peg, of the guide rail; a monitoring vehicle comprises a vehicle body and a monitoring vehicle controller, an electric guide wheel assembly connected with the monitoring vehicle controller is installed on the vehicle body, the vehicle body is erected on theguide rail through the electric guide wheel assembly and is provided with a position detector, a height detection device and a communication module, the position detector is connected with the monitoring vehicle controller to be used for detecting the position markers on the guide rail, the height detection device is connected with the monitoring vehicle controller to be used for obtaining vehiclebody height values when the vehicle body stops on the position markers one by one, and the communication module is used for sending the obtained vehicle body height values to a monitoring center.

Description

technical field [0001] The invention relates to the field of roadbed settlement monitoring, in particular to a monitoring system and method for roadbed settlement. Background technique [0002] Subgrade is an important part of railway line engineering. It is the basis for bearing the weight of track structure and train load, and it is also the weakest and most unstable link in line engineering. During the construction and after the completion of the project, the subgrade will inevitably deform under the action of load and other factors, resulting in uniform or uneven settlement. Post-construction settlement, especially uneven settlement, is likely to cause cracking, skewing and damage to the main structure of the railway, and may also have a certain impact on the surrounding buildings and underground pipelines. Therefore, considering the quality and safety of railway engineering, it is necessary to monitor and control subgrade settlement. [0003] Currently, the commonly u...

However, it is difficult to place the magnetic ring correctly, and the expansion and contraction of the scale itself affects the accuracy and interferes with the filling construction

[0004] Therefore, when faced with the settlement measurement of the straight section of the railway subgrade, the above methods are all traditional civil engineering methods, which generally have low measurement accuracy, require manual operation, slow information transmission speed, and can only measure the settlement of a single location. And disadvantages such as inconvenient use are not conducive to real-time monitoring of large-scale subgrade settlement
