High-speed railway structure settlement monitoring device and monitoring method

Abstract

The invention discloses a high-speed railway structure settlement monitoring device and a high-speed railway structure settlement monitoring method. In the device, a seal cover is arranged on the upper part of a liquid storage device; pressure transmission liquid is filled in the lower part of the liquid storage device; the upper part of the liquid storage device is connected with a first pressure leading-in end of a pressure transmitter through an air pipe; the lower part of the liquid storage device is connected with a second pressure leading-in end of the pressure transmitter through a pressure transmission pipe; an electrical signal output end of the pressure transmitter is connected with a data acquisition and transmission system electrically; the data acquisition and transmission system is communicated with a control centre. The device has a simple structure and high precision, is convenient to operate, and can realize long-term automatic monitoring of high-speed railway structure settlement in areas with harsh environment.

Description

technical field [0001] The invention belongs to the field of surveying and mapping science and technology, in particular to a settlement monitoring device and a monitoring method for high-speed railway structures. Background technique [0002] my country's railways are developing by leaps and bounds. New high-speed passenger dedicated lines and reconstruction of existing railways are in the ascendant. High-speed driving requires the line structure to provide a track system with high ride comfort. How to accurately monitor the settlement and deformation of structures has become a key technical issue for high-speed railways. [0003] There are two main types of traditional settlement deformation monitoring methods: one is the conventional measurement method (geodetic method and photogrammetry method); the other is the physical sensor method. Conventional measurement methods have the advantages of high measurement accuracy and reliable data, but they also have disadvantages s...

Problems solved by technology

However, its observation workload is large, its anti-vibration ability is low, it is greatly affected by climate, and it is difficult to realize continuous and automatic monitoring, and it is difficult to meet the requirements of passenger dedicated line settlement observation in terms of accuracy.

Although electronic levels and total stations can accurately test the settlement and deformation of foundation buildings, ground reference points need to be set, and they are greatly affected by climate and environmental factors, which seriously affect the accuracy of on-site testing.
