Problems solved by technology

[0002] In modern naval warfare and ocean development, blasting in deep water is widely used. For example, in modern naval warfare, it is often necessary to destroy underwater oil pipelines, water pipelines, underwater optical cables, cables, and underwater hydraulic structures. It is necessary to blast and remove sunken ships, abandoned oil well well pipes, and pile legs of water operation platforms; blasting reefs and deep-water cofferdams in the excavation of deep-water pipe trenches in marine development, construction of deep-water ports, and excavation of deep-water bridge pile foundation pits ; When drilling in oil wells and water wells, it is necessary to blast the drill pipe when the drill is stuck. These blasts are usually carried out in water tens of meters or even hundreds of meters deep, such as the blasting of abandoned oil well pipes in the deep sea. In recent years, there have been many blasts of this type, and there have been many successful cases. However, due to the influence of large water depths, there are also many failures. During deep water blasting, due to hydrological Due to the influence of underwater terrain and poor visibility, the operation is very difficult. Divers can only focus on diving equipment, and even need to manipulate underwater robots to perform operations. The operations are cumbersome and inefficient, and the reliability of charging and detonation network settings is poor. High, especially when destroying optical cables, cables, waste well pipes, oil pipelines and water pipelines or deepwater hydraulic structures in deep water, it is necessary to temporarily find targets and determine construction locations. These auxiliary operations are sometimes more difficult than blasting operations. For underwater destruction of unexploded torpedoes, sea mines, aerial bombs, deep bombs, etc., it is not only necessary to ensure the success of the blasting, but also to ensure that the explosives do not cause safety problems. The blasting operation is more difficult and there are more problems to be solved.
