With the acceleration of urbanization, the maintenance and renewal of pipelines and facilities has become one of the important projects. In these pipeline works, pipe diving installation is a common method. This article will introduce the basic knowledge and techniques of pipeline diving installation, as well as the things that need to be paid attention to during the pipeline diving installation process.
1. Basic knowledge and technology of pipeline diving installation.
Pipeline diving installation refers to a technique used by divers to install and repair pipes in the water. In pipeline diving installation, divers need to master the basic knowledge and skills of underwater construction, including underwater measurement, underwater cutting, underwater welding, underwater plugging, etc.
1.Underwater measurements.
Underwater measurement is one of the important aspects of pipeline diving installation. Divers need to use measuring instruments to measure the underwater topography, water depth, flow velocity, etc., in order to determine the location and depth of the pipe. During the survey, divers need to pay attention to safety to avoid being swept away by the current or other injuries.
2.Underwater cutting.
Underwater cutting is another important part of the installation of pipeline diving. During the installation of the pipeline, the old pipe needs to be cut and removed for the installation of the new pipeline. Divers need to use specialized underwater cutting equipment, such as plasma cutters or oxyacetylene cutters, to perform underwater cutting operations. During the cutting process, divers need to pay attention to safety and avoid injury due to improper handling.
3.Underwater welding.
Underwater welding is one of the key technologies for pipeline submersible installation. During the installation of the pipe, the new pipe needs to be welded. Divers need to master the basic knowledge and skills of underwater welding, such as welding current, welding angle, welding speed, etc. During the welding process, divers need to pay attention to safety and avoid injury due to improper operation.
4.Underwater plugging.
Underwater plugging is one of the necessary aspects of pipeline diving installation. During pipeline installation, the pipeline vulnerabilities need to be plugged. Divers need to master the basic knowledge and skills of underwater plugging, such as the selection of plugging materials and the determination of plugging methods. During the plugging process, divers need to pay attention to safety and avoid injury due to improper operation.
2. Precautions for pipeline diving installation.
During the installation of pipeline diving, the following things need to be noted:
1.Safety first.
Safety is paramount during the installation of a pipe submersible. Divers need to master the basic safety knowledge and skills of underwater construction, such as the use of diving equipment, emergency response, etc. At the same time, during the construction process, it is necessary to follow the relevant safety regulations and operating procedures to ensure the safety and quality of construction.
2.Preparation before construction.
Adequate preparation is required prior to the installation of the pipeline dive. These preparations include surveying the construction site, inspecting and maintaining the diving equipment, training and technical disclosure of the construction personnel, etc. These preparations can ensure the smooth progress of the construction process and the guarantee of construction quality.
3.Arrange the construction sequence reasonably.
In the process of pipeline diving installation, it is necessary to reasonably arrange the construction sequence according to the actual situation of the construction site and the requirements of the construction task. When arranging the construction sequence, it is necessary to consider factors such as the safety, quality and progress of the construction to ensure the smooth progress of the construction process and the timely completion of the construction task.
4.Pay attention to environmental protection.
During the installation of pipeline diving, attention needs to be paid to environmental protection. Divers need to avoid discharging waste and pollutants into the water to avoid adverse effects on aquatic life and the environment. At the same time, during the construction process, it is necessary to pay attention to the protection of the surrounding vegetation and environment to ensure the environmental protection and sustainable development of the construction process.
In short, pipeline diving installation is an important engineering technology, and it is necessary to pay attention to safety, quality, environmental protection and other aspects during the construction process. Only by making adequate preparations and implementing precautions can we ensure the smooth progress of the construction process and the smooth completion of the construction task.
