The invention discloses a method for reducing river bottom adsorption force through a seabed directional drilling machine, and belongs to the technical field of salvaging. According to the method, the directional drilling machine is used for conveying a drill rod or a hose to the lower portion of a sunken ship or a seabed device to jet high-pressure air, and therefore the foundation of the seabed adsorption force is broken; and adverse effects such as uncertainty of seabed adsorption force during salvage of seabed devices such as shipwrecks and the like are reduced.

    本发明公开了一种利用海底定向钻机减少江底吸附力的方法,属于打捞技术领域,本方法利用定向钻机,送钻杆或软管到沉船或海底装置的下部喷射高压空气,从而破除海底吸附力的基础,减少沉船等海底装置打捞时海底吸附力的不确定性等不利影响。
