Embodiment

[0046] The invention is suitable for settlement monitoring of structures (buildings, bridges, tunnels, etc.) in the field of engineering survey. For the convenience of description, this embodiment is as follows Figure 7 The closed leveling route shown is the description of the buried point, observation and calculation of the experimental object. The specific implementation steps are as follows:

[0047] 1. Buried subsidence monitoring signs

[0048] Firstly, common monitoring marks 2 are buried on the first subsidence monitoring object 1a, the second monitoring object 1b and the third monitoring object 1c. When embedding, it is necessary to ensure that the leveling rod 3 is suspended to facilitate leveling readings; at the same time, outside the deformation area of ​​the monitoring object Buried datum point 7.

[0049] 2. Observation and height difference calculation

[0050] The closed leveling route is observed clockwise, and there are a total of eight measuring stations...

Abstract

The invention discloses a leveling rod suspension type leveling measurement method for settlement monitoring. Hang the leveling rod with a suspension joint on the top to the monitoring mark, and carry out leveling observation after the leveling rod hangs naturally, and calculate the height difference of the station according to the different vertical ruler and hanging ruler methods of the front and rear leveling rods of the station, and then Combined with the reference points, the elevation and settlement of the monitoring marks can be calculated. The method of hanging the leveling rod of the present invention enables the measurement mark to be buried at a higher position, which solves the problem that the measurement mark is easily damaged, and also reduces the labor intensity of the work of holding the ruler during observation; at the same time, there is no need to switch the working mode of the instrument during observation, High work efficiency is guaranteed. The invention is mainly applicable to the settlement monitoring during the construction and operation of foundation projects such as building construction, tunnels and bridges.

Description

technical field [0001] The invention relates to a monitoring method for observing and obtaining settlement data by means of suspended leveling rods during the settlement monitoring process of buildings, tunnels and bridges, and belongs to the field of settlement monitoring in engineering surveying. Background technique [0002] Settlement monitoring is an important work content and safety guarantee during construction and operation of basic projects such as housing construction, tunnels and bridges. At present, geometric leveling is still the main method for the above-mentioned engineering settlement monitoring. It measures the height difference of each station and calculates the elevation of the monitoring point by combining the known elevation points, and then the settlement can be calculated. Leveling has the advantages of high precision and flexible route layout. However, there are some problems in practical applications. For example, settlement monitoring signs are usua...
