Acoustic tube is a commonly used testing equipment in large buildings such as bridges and subways, which is used to test the concrete strength and integrity of structures. Here's how to use the acoustic tube:
1. Preparation before installation.
Before the installation of the acoustic tube, a series of preparations need to be carried out. First of all, it is necessary to carefully check whether the specifications, models and quantities of acoustic tubes meet the design requirements, and check whether the acoustic tubes are damaged or deformed. At the same time, you need to be prepared with the tools and materials required for installation, such as wrenches, pliers, screwdrivers, sealants, etc.
2. Pretreatment before installation.
Before installing the acoustic tube, the reinforcement cage needs to be pre-treated. In general, the reinforcement cage needs to be fixed on the formwork, and the acoustic tube needs to be fixed on the reinforcement cage. Therefore, it is necessary to position and fix the reinforcement cage first. At the same time, it is necessary to measure and locate the installation position of the acoustic tube to ensure that the position of the acoustic tube is accurate.
3. Install the acoustic tube.
When installing the acoustic tube, one end of the acoustic tube needs to be fixed on the reinforcement cage and the other end is placed freely. Then, insert the free end of the acoustic tube into the detection instrument, and adjust the position and angle of the acoustic tube. When connecting the acoustic tube, it is necessary to seal and fix it with accessories such as sealing rings and fixing clips. During the installation process, you need to pay attention to the following points:
1.It is necessary to ensure that the position and angle of the acoustic tube are accurate to avoid deviations
2.It is necessary to ensure the tightness and stability of the acoustic tube to avoid slurry leakage or shaking;
3.During the installation process, it is necessary to check whether the acoustic tube is blocked or deformed at any time, and if there is any abnormality, it should be dealt with in time.
Fourth, testing and debugging.
After installation, the acoustic tube needs to be inspected and commissioned. First of all, it is necessary to check whether the acoustic tube is installed firmly and whether there is any leakage or deformation. Then, the acoustic tube needs to be pressure tested and debugged to ensure the tightness and stability of the acoustic tube. During the detection process, the following points need to be noted:
1.It is necessary to ensure the accuracy and reliability of the testing instrument;
2.It is necessary to ensure that the detection environment is quiet and stable;
3.It is necessary to avoid secondary damage to the acoustic tube during the detection process.
5. Maintenance and use.
When using and maintaining acoustic tubes, the following points need to be noted:
1.It is necessary to regularly check the tightness and stability of the acoustic tube to avoid slurry leakage or shaking
2.During use, it is necessary to avoid excessive shock and vibration to the acoustic tube;
3.When cleaning and maintaining, it is necessary to use appropriate detergents and tools for cleaning and maintenance;
4.It is necessary to ensure that the storage environment of the acoustic tube is dry and well-ventilated
5.During use, it is necessary to comply with the relevant safety operation procedures.
In short, the use of acoustic tubes needs to pay attention to many aspects, including pre-installation preparation, pretreatment, installation, testing and commissioning, maintenance and use. Only by mastering the correct use method can the accuracy and reliability of the acoustic tube be guaranteed, so as to provide a guarantee for the quality of the building.
