First, the background of the project.
With the continuous development of water conservancy engineering, diver underwater installation and demolition technology has become an important construction method. In some specific underwater projects, such as reservoir dams, ship locks, sluices, etc., concrete mold bag construction is a widely used construction technology. Divers carry out installation and dismantling work in the water, and can efficiently complete the underwater concrete mold bag construction task.
2. Underwater installation and dismantling technology for divers.
The underwater installation and removal technology of divers mainly includes two links: underwater installation and demolition. During the installation process, divers need to accurately and quickly install the concrete mold bags in their intended location and ensure the quality and safety of the installation. During the dismantling process, divers need to remove the concrete mold bags that have been damaged or need to be repaired, and transport them to a safe place for disposal.
3. Technical difficulties and solutions.
1.Low Underwater Visibility: Poor underwater visibility is a challenge for divers to install and dismantle techniques underwater. To solve this problem, the reservoir can be adequately drained and ventilated before construction to improve underwater visibility. At the same time, measures such as local lighting, increasing the number of divers and technical exchanges can be taken in the construction to improve work efficiency and construction quality.
2.Current Impact: Current is another difficulty in the diver's underwater installation and removal technique. In order to overcome the effects of water flow, the reservoir can be measured and evaluated before construction, determining the speed and direction of the water flow. At the same time, appropriate measures can be taken during construction, such as changing the diver's posture and breathing pattern, to reduce the impact of water flow on the installation and demolition work.
3.Complex operating environment: The underwater operating environment is complex and changeable, and various unforeseen circumstances may be encountered. In order to cope with this situation, it is necessary to conduct comprehensive training and assessment of divers to improve their skills and psychological quality. At the same time, safety measures need to be taken during construction, such as the use of equipment such as safety ropes and life jackets, to ensure the safety and health of divers.
Fourth, the application prospects.
With the continuous development of water conservancy engineering, the application prospect of diver underwater installation and demolition technology in water conservancy engineering is becoming more and more broad. Especially in some water conservancy projects in deep water areas and complex waters, diver underwater installation and demolition technology has an irreplaceable role. In the future, with the continuous progress of technology and the continuous expansion of the application range, the underwater installation and removal technology of divers will be more widely used and developed.
V. Conclusions. Diver underwater installation and dismantling technology is an important construction method in hydraulic engineering. In concrete mold bag construction, divers can complete the installation and dismantling work through skilled technology and rich experience, and overcome difficulties such as low underwater visibility and the influence of water currents. With the continuous development of water conservancy engineering, the application prospect of underwater installation and demolition technology for divers will become more and more broad.
