Methods and steps of underwater plugging
1. In the event of a water leak, the following measures should be taken immediately:
1.Immediately stop the relevant operations, quickly report to the superior and call the emergency ** to notify other personnel to carry out rescue;
2.Turn off the source of the leak;
3.Open the emergency drain and discharge the leaked water into the designated drainage system;
4.Clean up the leakage site to avoid secondary pollution.
Second, the leakage plugging method:
1.Direct plugging method: suitable for situations where the water pressure is not large. Adjust the plugging agent into a paste to quickly and directly plug the leakage;
2.Indirect blockage method: suitable for situations with high water pressure. Paint a layer of cement mortar, waterproof paint and other materials around the leakage, and then plug the gap with a plugging agent
3.Crack plugging method: suitable for the situation of high water pressure. Paint a layer of cement mortar, waterproof paint and other materials around the leakage, and then plug the gap with a plugging agent
4.Spraying method: spray the plugging agent on the leakage to quickly form a thin film to achieve the purpose of plugging the leakage
5.Waterproof tape plugging method: Wrap the waterproof tape around the leakage, and then plug the gap with a plugging agent.
3. Plugging steps:
1.Investigate the cause of the leak: understand the specific situation of the leak, such as the leak location, the cause of the leak, etc.;
2.Clean up the site: clean up the debris and sewage at the leakage site to create a good environment for the plugging work
3.Determine the plugging scheme: select the appropriate plugging method according to the cause of the leakage
4.Prepare plugging materials: Prepare the corresponding plugging materials according to the selected plugging method;
5.Implement plugging: plug the leak according to the selected plugging method;
6.Check the plugging effect: After the plugging is completed, observe for a period of time to ensure that the plugging effect is stable before proceeding to the next step.
4. Precautions:
1.When plugging leaks, protective equipment such as gloves, masks, glasses, etc. should be worn
2.Avoid using open flames or high-temperature items at the leakage site to avoid disasters or accidents
3.When using leakage plugging materials, they should be used in accordance with the instructions or the guidance of professionals to avoid secondary pollution or damage
4.After the leakage plugging is completed, the site should be cleaned up to keep the site clean and hygienic.
