During the construction period of the piezometer embedded inside the segmented concrete, a series of protective measures must be taken to ensure the correct installation and integrity of the piezometer. Here's a detailed description of these protections:
1. The piezometer inside all segmented concrete must be embedded when the segment is prefabricated. Before pouring concrete for the segments, the cables and waterproofing devices must be installed, and the cable connector protection box must be reserved. This protects the cable connector from damage while preventing water and other impurities from entering the cable joint.
2. In the process of segment concrete pouring, the piezometer must be tracked and protected. This includes ensuring that the concrete is poured without crushing or impacting the piezometer to avoid damage. In addition, after the segment prefabrication is complete, the sensor should be checked in good condition to ensure that it is working properly.
3. Before the segment assembly construction, the cable joint should be completely protected. This prevents damage to the cable joints during the assembly process. At the same time, personnel should be sent to track the assembly of the monitoring section, and make relevant preparations to ensure that problems can be solved in time.
4. When the piezometer outside the segment is installed, it is necessary to accurately grasp and record the accurate position of the embedded, so as to find the location of the measuring point after the template is removed. This avoids unnecessary troubles caused by not being able to find the measurement point in the later monitoring process.
5. After the piezometer is installed, the sensor readings need to be tested to ensure the integrity of the sensor. This can be done by comparing it to the expected data, and if there are any anomalous data or errors, it needs to be adjusted and fixed in a timely manner.
Through the above measures, the piezometer can be effectively protected from damage during construction, ensuring its normal operation and being able to provide accurate monitoring data for civil engineering. When carrying out civil engineering monitoring, it is necessary to pay attention to the working status of the piezometer at all times, and take corresponding protective measures in time to ensure the smooth progress of the project.
