Different from traditional excavation, underwater excavation faces a series of difficulties. First of all, the resistance of water itself will increase the difficulty of excavation. If the angle and intensity are not well controlled, you will get twice the result with half the effort if you are not careful. This requires more sophisticated equipment and more exquisite operation technology, and the training is becoming more and more difficult. Secondly, the underwater environment is completely different from that on land. A slight rotation may cause a large range of sediment to become turbid, so the operation speed will also decrease. Coupled with some troubles such as low visibility, inconvenient maintenance, and the need to supplement oxygen, every link is more complicated and the requirements for each worker are higher. When you see an underwater project, don't think it's just that simple to dig. After all, excavators on land are already difficult to operate.
Although the troubles have increased, the technology is also improving. From the traditional open-pit excavator to the safer carriage that appeared later, the underwater excavator has been assembled more closely now. People's hearts are because "water can conduct electricity, is it dangerous to start the machine?" Underwater operation is playing a role in more and more fields, and it is believed that various devices and measures will be more and more perfect, so that underwater operators can have better working conditions. After all, the underwater world is getting closer and closer to our life now. In its embrace, there are not only convenient and stable traffic arteries, but also countless rich energy treasures. I believe that with the leap of science and technology in the future, mankind will be able to create a more convenient and livable living environment without causing damage.
