Horizontal multi-point settlement monitoring device and monitoring method based on hydraulic measurement

Abstract

The invention discloses a horizontal multipoint settlement monitoring device and a monitoring method thereof based on hydraulic measurement, which are used for settlement monitoring of buildings such as roadbeds or bridges. The monitoring device comprises a liquid storage tank arranged at a datum point part, monitoring containers, silicon micro differential pressure sensors, settlement collecting instruments and a settlement plate used for anchoring the silicon micro differential pressure sensors, wherein the monitoring containers, the silicon micro differential pressure sensors and the settlement collecting instruments are arranged at the datum point part and monitoring point parts; the liquid storage tank and the monitoring containers are communicated through communication pipes; membranes of the silicon micro differential pressure sensors are in contact with the liquid levels in the monitoring containers; the output ends of the silicon micro differential pressure sensors are connected with the input ends of the settlement collecting instruments; and all the silicon micro differential pressure sensors are communicated with the same air pipe. The monitoring method is achieved via the monitoring device; and according to the monitoring method, the pressure of the monitoring points and the datum point is detected through the silicon micro differential pressure sensors to obtain elevation changes of the monitoring points relative to the datum points, and then settlement changes are obtained through calculation. The monitoring device has the advantages of high measurement precision, good stability and simpleness and convenience in field mounting; and automatic monitoring is easily realized.

Description

technical field [0001] The invention relates to settlement monitoring of roadbeds or bridges and similar buildings, in particular a horizontal multi-point settlement monitoring device based on hydraulic measurement and a monitoring method thereof, which is especially suitable for differential settlement monitoring at joints of roads, bridges or road tunnels. Background technique [0002] The high-speed running of high-speed railway and passenger dedicated line needs to provide a high smoothness and stability of the sub-rail foundation. Since the high-speed railway passenger dedicated line is very sensitive to longitudinal uneven settlement, it is required that the high-speed railway and passenger dedicated line have strict control of subgrade settlement. [0003] At present, subsidence monitoring usually uses a level instrument or a total station for manual monitoring, but the railway passenger dedicated line has a long line, many monitoring sections, and a large amount of me...

AI Technical Summary

Problems solved by technology

[0003] At present, subsidence monitoring usually uses a level instrument or a total station for manual monitoring, but the railway passenger dedicated line has a long line, many monitoring sections, and a large amount of measuring point data. Manual monitoring is time-consuming, laborious, heavy workload, and the monitoring results are greatly affected by human factors. shortcoming

The static level measures the elevation change by the position of the liquid level, the long-term stability is relatively poor, the anti-interference ability is poor, and it is difficult to realize the automatic monitoring of multi-point settlement
