Diver underwater exploration and inspection is an important work in bridge reinforcement engineering. When carrying out bridge reinforcement construction, divers need to go deep underwater to conduct exploratory inspections to determine the structural condition of the bridge and the parts that need to be reinforced. This article will introduce the process, methods and precautions for divers to explore and inspect underwater.
1. The process of underwater exploration and inspection of divers.
1.Preparation.
Thorough preparation is required before a diver's underwater exploration check can be performed. First, the diver's qualifications and experience need to be determined to ensure that they are capable of conducting underwater exploration inspections. Secondly, you need to prepare diving equipment and tools, such as wetsuits, breathing apparatus, probes, etc. Finally, divers need to be trained in safety and skills to ensure that they are able to safely carry out underwater exploration inspections.
2.Check before you get into the water.
Before a diver enters the water, diving equipment and tools need to be inspected to ensure that they are in good working order. At the same time, the diving environment needs to be evaluated, such as water temperature, water depth, flow rate, etc., to ensure that divers can safely carry out underwater exploration inspections.
3.Get out into the water.
After the divers are in the water, the bridge needs to be probed and inspected using a probe. In the process of exploration, it is necessary to carefully observe the structural condition of the bridge, including piers, bridge decks, bridge abutments and other parts. At the same time, it is necessary to observe the surrounding environment of the bridge, such as water flow, water temperature, water quality, etc., to ensure the safety and stability of the bridge.
4.Recording and analysis.
During the exploration process, the results of the exploration need to be recorded and analyzed. The contents of the record include the structural condition of the bridge, the parts that need to be reinforced, the surrounding environment, etc. The analysis includes the stability and safety assessment of the bridge, the design of the reinforcement scheme, etc.
2. Methods of underwater exploration and inspection by divers.
1.Visual inspection.
Visual inspection is one of the basic methods of underwater exploration inspection for divers. Through visual inspection, the structural condition of the bridge and the surrounding environment can be visually observed. During the visual inspection, a probe is required to make a comprehensive observation and documentation of the bridge.
2.Acoustic sounding.
Acoustic detection is another method for divers to explore and inspect underwater. Through acoustic detection, it is possible to determine the structural condition of the bridge and the parts that need to be reinforced. In the process of acoustic detection, it is necessary to use acoustic detectors to detect the bridge, and determine the structural condition and position of the bridge according to the signal reflected back by the sound waves.
3. Precautions for underwater exploration and inspection of divers.
1.Safety first.
Safety is paramount when conducting underwater exploration inspections for divers. Therefore, when choosing divers, it is necessary to choose experienced divers and conduct safety training and skill training on them. At the same time, it is necessary to strictly follow the safety regulations and operating procedures during the diving process to ensure the safety of divers.
2.Hold your horses.
It is very important to stay calm in the underwater environment. In the event of an emergency or physical discomfort, it is necessary to take timely measures to deal with it. At the same time, it is necessary to maintain concentration and patience during the dive process to avoid emotional fluctuations affecting the results of the exploration examination.
3.Take care of the environment.
Care needs to be taken to protect the environment when conducting underwater exploration inspections for divers. During the exploration process, it is necessary to avoid damage or pollution to the surrounding environment. At the same time, the waste generated needs to be properly treated and disposed of.
In short, the underwater exploration and inspection of divers is an important work in bridge reinforcement engineering. Diver exploration inspections require thorough preparation, safety, calm, and environmental protection. Through the correct operation and safety measures, the safety of divers and the accuracy of exploration results can be ensured, and reliable data support can be provided for bridge reinforcement projects.
