Detailed explanation of the installation steps of the subgrade settlement plate observation pile
1. Preparations.
Sufficient preparation is required before the installation of subgrade settlement plate observation piles. First of all, it is necessary to understand the specific situation of the project, including the scale of the roadbed, geological conditions, construction environment, etc. Based on this information, a reasonable installation plan and emergency plan are formulated. At the same time, it is necessary to ensure that the required equipment and materials are complete, including settlement plate observation piles, measuring instruments, installation tools, etc. And quality inspection of these equipment and materials is carried out to ensure that their performance meets the requirements.
2. Site cleaning and measurement lofting.
Before installation, it is necessary to clean up the debris and obstacles in the installation area to ensure that the site is flat and clean. At the same time, it is necessary to carry out measurement and lofting to determine the specific position of the settlement plate observation pile. When lofting, it is necessary to take into account the layout requirements and observation accuracy of the observation points to ensure that each observation point can accurately reflect the settlement of the roadbed.
3. Inspection of installation equipment and materials.
During the installation process, various equipment needs to be used, such as cranes, pile drivers, etc. These devices need to be inspected to ensure that they are performing well, safely and reliably. At the same time, the settlement plate observation pile should be inspected to ensure that its quality meets the requirements and there is no damage or deformation.
Fourth, the installation process.
In the installation process, it is necessary to operate in the order of first positioning the plate and then installing the settlement observation rod. First of all, the positioning plate should be fixed to ensure that its position is accurate and stable. Then, the settlement observation rod is to be installed, which is firmly connected to the positioning plate. During the installation process, it is necessary to ensure that the connection of each component is tight and stable to avoid loosening and falling off. At the same time, pay attention to the direction of the observation pole and make sure that it is perpendicular to the ground.
5. Adjustment and calibration.
After the installation is completed, the settlement plate observation pile needs to be adjusted and calibrated. The adjustment is mainly to adjust the height of the observation rod so that it is perpendicular to the ground. Calibration adjusts the position and accuracy of the observation point through actual measurement and calculation to ensure that it meets the requirements. In the calibration process, measuring instruments such as levels and total stations can be used to measure and calibrate parameters such as elevation and angle.
6. Daily maintenance and maintenance.
After the installation of the settlement plate observation pile is completed, regular maintenance and maintenance are required. This includes inspection, cleaning, maintenance, etc. of the observation equipment. At the same time, it is necessary to collect and analyze the settlement data on a regular basis, and find and deal with abnormal situations in time. During the maintenance process, it is necessary to pay attention to keeping the equipment dry and tidy to avoid damage and rust. For the parts that have problems, they should be replaced or repaired in time to ensure that they perform well.
7. Data collection and analysis.
The main function of the settlement plate observation pile is to monitor the settlement of the roadbed, so the collection and analysis of data is very important. Settlement data should be collected on a regular basis, either automatically or manually. After the collection is completed, the data should be analyzed and processed to understand the settlement trend and law of the subgrade. Abnormal data should be discovered and processed in time to avoid affecting the safety and quality of the project.
To sum up, the installation of subgrade settlement plate observation pile is a highly technical work, which needs to follow certain steps and requirements. In practice, it is necessary to strictly abide by the relevant norms and standards to ensure that the installation quality and observation accuracy meet the requirements. At the same time, it is necessary to strengthen daily maintenance and maintenance work to ensure the long-term stable operation of the equipment. Through scientific data collection and analysis methods, the settlement of the roadbed can be effectively monitored, and the safety and quality of the project can be guaranteed.
