Description :
If the construction process is temporarily suspended, observation should be conducted once during the suspension and once again during the resumption of work. If there is a sudden increase or decrease in ground load near the foundation, a large amount of water collection around the foundation, or prolonged continuous rainfall, the number of observations should be increased in a timely manner. When a building suddenly experiences significant settlement, uneven settlement, or severe cracks, continuous observations should be conducted immediately on a daily or daily basis. If the settlement is still unstable after the completion of the building, observation should continue during the use phase. Judgment of settlement stability: In general observation projects, if the settlement rate is less than 0.01-0.04mm/day, it can be considered that the settlement stability stage has been entered.
In the process of measurement and surveying, there is inevitably a need for settlement observation. Settlement observation markers, benchmark markers, etc. are all measurement markers used for settlement observation. There are many reasons that can cause errors in the measurement process. Below, we will introduce them to you. In the process of measurement and surveying, there is inevitably a need for settlement observation. Settlement observation markers, benchmark markers, etc. are all measurement markers used for settlement observation. There are many reasons that can cause errors in the measurement process. Below, we will introduce them to you.
1. Burial errors of measurement points and markers. The measurement points for settlement observation include working base points, reference points, and observation points. If these measurement points are not accurately or stably buried, errors may occur, and the burial of settlement observation targets themselves may also have errors.
2. Errors caused by environmental conditions. People are in the external environment, and changes in the environment can have a certain impact on measurements, such as wind force, atmospheric refraction, etc., which can cause errors in the line of sight during measurements.
3. Instrument error and personnel operation error. The instrument comes with certain errors during production, and the presence of personnel errors can cause measurement errors.
In the process of using settlement observation markers for measurement, instrument errors, personnel operation errors, point and marker embedding errors may all cause actual measurement errors. Therefore, when purchasing measurement markers and instruments, it is necessary to find manufacturers to purchase them.
