[0003] At present, the conventional underwater drilling construction technology adopts the "two pipes and one drill" drilling method: "two pipes" refers to the casing and drill pipe, and "one drill" refers to the impact drill bit. After the construction personnel control the drilling device on the ship to drill holes in the underwater rock formation, they need to withdraw the impact drill bit and drill pipe to send explosives into the hole. When the water surface fluctuates greatly, the position of the drill hole is easy to be lost, and it is difficult to bury the explosives, which affects the efficiency of rock breaking. Therefore, we proposed an underwater rock breaking device to solve the above problems. Summary of the invention
