With the continuous development of urban construction, the demand for underwater engineering is increasing. As an important underwater operation method, frogman diving cutting and demolition plays an increasingly important role in urban construction. This article will introduce the basic principles, application scope, construction process and precautions of frogman diving cutting and demolition, so that readers can better understand this field.
First, the basic principle of frogman diving cutting and demolition.
Frogman diving cutting and demolition refers to the process of cutting and dismantling structures by frogman divers using special cutting tools in the water. In frogman diving cutting and demolition, the main cutting tools used include flame cutting, laser cutting, plasma cutting and waterjet cutting. These tools use different principles to cut the structure for the purpose of demolition.
Second, the application scope of frogman diving cutting and dismantling.
Frogman diving cutting and demolition is widely used in various underwater projects, such as bridges, docks, docks, tunnels, pipelines, etc. In these works, dismantling and replacement are required due to the deterioration and damage of the structure. With frogman diving cut and dismantling, these tasks can be completed quickly and efficiently while reducing the impact on the surrounding environment.
3. The construction process of frogman diving cutting and demolition.
1.Preparation: First of all, it is necessary to investigate and analyze the underwater environment, determine the location and extent of the cut. At the same time, you need to prepare the required equipment and tools, such as frogman diving equipment, cutting tools, etc.
2.Diving operations: Frogman divers need to put on diving equipment and enter the water for diving operations. In the course of the operation, it is necessary to maintain contact with the command personnel on the surface to ensure the safety and smooth progress of the operation.
3.Cutting operation: After determining the cutting position, the frogman diver uses a special cutting tool to cut the structure. During the cutting process, it is necessary to pay attention to controlling the speed and depth of cutting to avoid affecting the surrounding structure.
4.Demolition Operations: After the cutting is completed, the frogman diver needs to dismantle the cut structure. During the demolition process, it is necessary to pay attention to maintaining the safety and stability of the operation and avoiding the impact on the surrounding environment.
5.Floating: After the demolition is completed, the frogman diver needs to surface for subsequent treatment and cleanup. In the process of operation, it is necessary to pay attention to maintaining contact with the command personnel on the water surface to ensure the safety and smooth progress of the operation.
Fourth, the precautions for frogman diving cutting and dismantling.
1.Safety first: Safety must be a top priority when performing frogman diving cutting demolitions. Before the operation, it is necessary to conduct a full investigation and analysis of the underwater environment, and formulate a detailed operation plan and safety measures. At the same time, it is necessary to select experienced frogman divers to carry out the operation to ensure the safety and smooth progress of the operation.
2.Control the underwater environment: When performing frogman diving cutting and demolition, you need to control the underwater environment. There are various uncertainties in the underwater environment, such as water flow, temperature, pressure, etc. Therefore, it is necessary to conduct a full investigation and analysis of the underwater environment before carrying out the operation, and formulate a detailed operation plan and safety measures. At the same time, it is necessary to pay attention to controlling the changes in the underwater environment during the operation to avoid affecting the operation.
3.Comply with relevant regulations: When performing frogman diving cutting and dismantling, you need to comply with relevant regulations and laws and regulations. Before carrying out the operation, it is necessary to fully understand and analyze the relevant regulations, laws and regulations to ensure the legality and compliance of the operation. At the same time, it is necessary to pay attention to comply with relevant regulations and the requirements of laws and regulations during the operation to avoid affecting the surrounding environment.
4.Keep records and summaries: Record and summarize when performing frogman diving cutting and demolition. In the process of operation, it is necessary to record and analyze the operation in detail, including the operation time, place, personnel, equipment, etc., and at the same time, it is necessary to summarize and analyze the problems and deficiencies in the operation process, so as to better improve the efficiency and safety of the operation.
