Guidelines for underwater inspection construction
I. Introduction. Underwater inspection is an important task in engineering construction, which plays a vital role in ensuring the quality and safety of the project. However, due to the complex and changeable underwater environment, underwater inspection is difficult and dangerous. Therefore, this guide is intended to provide some practical advice and guidance to help construction crews carry out underwater inspection work and ensure that the project runs smoothly.
2. Overview of underwater inspection.
Underwater inspection refers to the process of observing, detecting, and evaluating buildings, equipment, etc., in or under water. The purpose of underwater inspection is to discover potential safety hazards and problems in a timely manner, and to provide a basis for subsequent repair and emergency repair work. When conducting underwater inspections, specialized equipment and techniques are required, while safety needs to be taken into account.
3. Underwater inspection equipment.
1.Diving equipment: including wetsuits, goggles, respirators, diving shoes, etc. These devices protect the diver's body and respiratory system while providing better visual and auditory effects.
2.Underwater photography equipment: including underwater cameras, lights, tripods, etc. These devices help divers record underwater conditions and details.
3.Measuring equipment: including sounder, water thermometer, water pressure gauge, etc. These devices can measure parameters such as depth, temperature, and pressure under water, providing a basis for assessing the underwater environment and the state of buildings.
4.Other equipment: According to the actual needs, it can also be equipped with diving knives, lifesaving ropes, locators and other equipment.
Fourth, underwater inspection technology.
1.Diving technology: Divers need to master the basic skills and knowledge of diving, including the formulation of diving plans, the operation and maintenance of diving equipment, and the knowledge of diving medicine.
2.Underwater Photography Techniques: Divers need to master the basic skills and knowledge of underwater photography, including the operation and maintenance of photographic equipment, underwater composition, and light control.
3.Measurement techniques: Divers need to master the use and maintenance of measuring equipment, including depth gauges, water thermometers, water pressure gauges, etc.
4.Other technologies: According to actual needs, you can also learn Xi underwater navigation, underwater salvage and other technologies.
5. Underwater inspection process.
1.Formulate an inspection plan: According to the needs of the project and the actual situation, formulate a detailed inspection plan, including the time, place, personnel and equipment of the inspection.
2.Prepare the inspection equipment: According to the plan, prepare the corresponding inspection equipment and technology.
3.Conduct underwater inspections: According to the plan, divers carry out underwater inspection work, recording the results and details of the inspections.
4.Analyze the inspection results: Analyze and evaluate the inspection results to identify potential safety hazards and problems.
5.Carry out repair work: According to the analysis results, carry out corresponding repair and emergency repair work.
6.Regular review: After the restoration work is completed, a regular review is carried out to ensure the quality and safety of the project.
6. Precautions.
1.Safety first: When conducting underwater inspections, always put safety first. Ensure that divers have the appropriate skills and knowledge to use reliable equipment and instruments.
2.Compliance: Comply with relevant diving regulations and operating procedures to ensure the safety of divers and water workers.
3.Protecting the environment: When conducting underwater inspections, pay attention to protecting the marine environment and avoid causing damage to marine life and coral reefs.
4.Detailed records: Detailed records of the inspection results, including the ** and video recordings. This information can provide a basis for subsequent analysis and evaluation. At the same time, it can also be used as part of the project dossier for future reference and use.
