Railway settlement monitoring system and online monitoring method

Abstract

The invention provides a railway settlement monitoring system and an online monitoring method. The monitoring system comprises a data collection station, a benchmark hydrostatic level gage and a monitoring hydrostatic level gage, wherein the data collection station, the benchmark hydrostatic level gage and the monitoring hydrostatic level gage are respectively provided with a cable connector, and the cable connector on the benchmark hydrostatic level gage and the cable connector on the monitoring hydrostatic level gage are connected with the data collection station through a cable after being serially connected with each other; the benchmark hydrostatic level gage and the monitoring hydrostatic level gage are respectively provided with a ventilation pipe connector and a liquid pipe connector, the ventilation pipe connectors on the benchmark hydrostatic level gage and the monitoring hydrostatic level gage are serially connected with each other through a gas pipe, and the liquid pipe connectors on the benchmark hydrostatic level gage and the monitoring hydrostatic level gage are serially connected with each other through a liquid pipe. The automatic monitoring of the settlement situation of a railway foundation, bridges and culverts, tunnels and transitional sections can be realized on the basis of the inductance frequency regulation principle and the intelligent monitoring method, the manual intervention factor is effectively eliminated, the measuring precision is improved, and the labor intensity of workers can be alleviated.

Description

technical field [0001] The invention belongs to the field of basic engineering monitoring such as railways and highway subgrades, and in particular relates to a railway settlement monitoring system and an online monitoring method. Background technique [0002] Land subsidence is also known as ground subsidence or ground subsidence. In the "Regulations on the Prevention and Control of Geological Disasters", it is defined as "slowly varying geological disasters". , a local downward movement (or engineering geological phenomenon) that causes the elevation of the crustal surface to decrease. The subgrade surface of railways and highways, especially the transitional sections of roads and bridges, will cause subsidence, bridges, tunnels, and transitional sections to settle due to loads, construction quality, and regional settlement (groundwater mining, surrounding construction, etc.) during the construction process and after the completion of the construction. At present, the met...

AI Technical Summary

Problems solved by technology

[0003] (1) The measurement accuracy is low: the measurement equipment needs to be checked and calibrated regularly; the measurement accuracy is greatly affected by the quality of technicians and professional technical level;

[0004] (2) Greatly affected by weather factors: manual measurement is greatly affected by weather factors, and has high requirements for climatic conditions such as visibility, temperature, and humidity;

[0005] (3) Manual participation is required to manually record the data and enter the data into the database, which cannot realize unattended measurement around the clock;

[0006] (4) During the operation of the railway, it is difficult to guarantee the continuity, accuracy and real-time performance of the above artificial settlement observation method
