Abstract

The invention concerns a hammer for driving piles underwater on ocean, sea, lake or river floors. It helps to fix piles in vertical or horizontal direction, as well as tilted at any angle to the vertical. The hammer is suitable for driving piles serving as anchors to which oil platforms are attached through cords. The hammer includes an impact part moving along guides, bottom-up and top-down, with the help of rocket engines immovably fixed to it. The rocket engines can be chemical or catalytic. In another variant, the rocket engines can be electrical using as working medium the surrounding water, no matter whether it is salt or sweet, and also a laser can be used as a source of energy for heating. The main advantage of the invention is that it proposes work underwater without hammer hermetization and ensures working in air or gaseous environment. This allows work at any depths including the deepest spots in the oceans. The use of rocket engines for moving the impact part allows reaching any blow speed as well as practically unlimited energies of the impact. The hammer proposed ensures driving of piles at an increased speed, at any angle in the space as well as realizing a complicated impact.
