A Simple Monitoring Method for Building Displacement and Attitude

Abstract

The invention discloses a method for carrying out simple monitoring on the displacement postures of buildings. The invention belongs to the technical field of building posture monitoring. A method for carrying out simple monitoring on the displacement postures of buildings is characterized by comprising the following monitoring steps of arranging a measure point positioning component on a moved building or an underpinning structure thereof, setting a monitoring line between building measure points, applying a pretension force to the monitoring line, so that the monitoring line is kept in a horizontal state, and arranging a displacement sensor at each building measure point; and when the building is moved, monitoring the displacement of the building measure points through the displacement sensors, and according to the displacement range and change data of the building measure points, carrying out real-time monitoring on the displacement postures of the building. The method disclosed by the invention has the advantages of simple facilities, easiness for operation, simple method, low cost, intuitive results, and the like, and can be widely applied to the simple and rapid real-time monitoring on the displacement postures of buildings.

Description

technical field [0001] The invention belongs to the technical field of building posture monitoring, in particular to a simple monitoring method for building displacement and posture. Background technique [0002] At present, with the large-scale development of urban planning and renovation, many existing buildings with preservation value can be moved to the planned new site through the overall building displacement technology. The overall building displacement technology is a technology with considerable technical difficulty and risk. In order to ensure the safety of the building during the displacement process, it is very necessary to carry out comprehensive real-time monitoring. [0003] The most important monitoring parameters include the uneven settlement of the house, the difference in the movement of each measuring point and the torsion of the house. These monitoring parameters can intuitively reflect the overall posture of the house. At present, the commonly used obs...

Problems solved by technology

At present, the commonly used observations of settlement and settlement difference in engineering use level instruments, theodolite observations or level pipe observations. The use of level instruments and theodolite observations for settlement observation takes a long time, and the data of each measuring point changes at any time during the displacement process, so the data collection is not at the same time; Observation accuracy is low by leveling tube, and the result is affected by the diameter of the tube, whether it is bent or not, etc.

The movement formation difference is tested by pasting the ruler on the track, or collecting the sensor readings in the PLC automatic control system. It is convenient to read the pasted ruler, but it is necessary to read all the data to compare the stroke difference of each measuring point. For the rotation and displacement, all the measured Point values ​​are converted into radians for comparison; the displacement sensor in the PLC system is convenient for reading, but there are technical problems such as the cumulative displacement cannot be given, and the cumulative displacement cannot reflect the real posture of the house.
