We previously discussed the requirements before starting underwater leakage plugging projects. As you all know, underwater leakage plugging is a highly complex underwater operation. Negligence during the work could lead to pollutant leaks, and in severe cases, it could even pollute the surrounding environment. It is, therefore, a very meticulous task. Today, we want to share some key points to pay attention to when conducting underwater repair work.

Firstly, familiarize yourself with the pool's structure. To minimize time spent underwater during maintenance work, each staff member must be well-versed in the underwater environment prior to diving. They should also have a detailed understanding of the engineering structure to be repaired. Additionally, they should be thoroughly familiar with the entire maintenance process. This way, once underwater, staff can quickly carry out the maintenance tasks.

Before diving, divers must be well-informed about the local hydrological conditions, particularly the underwater environment, temperature, and flow rates. This knowledge helps staff select appropriate equipment to prevent unexpected underwater incidents.

Three, underwater sealing operations must be handled with caution. When performing underwater cutting, welding, and other destructive or repair actions, it is crucial to take appropriate protective measures to prevent internal wastewater leakage during maintenance from harming the surrounding natural environment.

Ensure thorough confirmation upon completion of underwater work. It is crucial to double-check repairs to leaks or other engineering structures to avoid the need for a second repair.
