In the work of the settling plate manufacturer, the laying of the working base point mark is a very important part. The working base point marker is the reference point used to determine the position and elevation of the settlement plate, and is the starting point for settlement observation. The following points need to be paid attention to when laying the working base point mark:
1.Determines the location of the datum point.
In settlement observation, the location of the datum point is very important. The datum point should be selected in a relatively stable place, such as a wall around a building or on a load-bearing column. At the same time, the height of the reference point should be the same as the height of the settlement plate for easy observation and calculation.
2.Determine the shape and size of the logo.
The shape and size of the working base point marker should be determined according to the specific situation of the settlement plate and the observation requirements. In general, signs should be in the shape of a circle or square to facilitate observation and recording. The size should also be selected according to the actual situation, generally using a circle with a diameter of about 100mm or a square with a side length of about 200mm.
3.The method of embedding the sign.
The following points need to be paid attention to when burying the working base point marker:
Before burial, the buried position should be cleaned and leveled to ensure the stability and accuracy of the mark.
The sign should be buried perpendicular to the ground to ensure the accuracy of the observations.
Attention should be paid to the protection of the sign when burying to avoid damage or contamination.
4.Observation and recording.
When observing and recording, the following points need to be noted:
The position of the datum point and the settlement plate should be measured and recorded before the observation.
High-precision measuring instruments, such as total stations or laser rangefinders, should be used for observation.
Data should be recorded in a timely manner after each observation, and data processing and analysis should be carried out.
In short, settlement plate manufacturers need to pay attention to details and accuracy when laying the working base point markers to ensure the accuracy and reliability of settlement observation. At the same time, it is also necessary to be careful and careful when observing and recording data, and to process and analyze data in a timely manner, so as to provide accurate reference data for the project.
