Description
Technical Field
The invention relates to the technical field of deep-sea steel pipe pile recovery, in particular to a deep-sea steel pipe pile separation recovery device and a construction method.
Background
With the development of technology and the need of national integral interests, the construction of cross-sea bridges has become an urgent problem to be solved in bridge engineering. The construction of the cross-sea bridge requires the construction of a temporary use platform in the deep sea, and the most common temporary foundation form is a steel pipe pile. Steel pipe pile recovery is usually performed by underwater cutting operation, but when deep sea operation with a water depth exceeding 30m is encountered, diving cutting cannot be performed, and even in shallow water, cutting operation has a large safety problem because the seawater flow force is large and the flow direction is not easily grasped. Another common method is pile pulling through barge and pile pulling equipment, but the steel pipe pile is large in rock depth, the sea water is deeper, and the pile is not easy to pull out.
To the above-mentioned problem, a new steel-pipe pile form appears, and the steel-pipe pile is divided into two parts, through threaded connection, but through crane rotation recovery part, carries out whole recovery during the recovery. However, this method has a number of problems: first, the crane rotation cannot provide enough torque to separate the two pile shafts. In addition, when the whole pile is recovered, the general pile body is longer in a deep sea environment, and the whole pile body cannot be recovered in place once due to the limitation of the length of hoisting equipment and a barge. Finally, after the pile body is separated, the pile body is partially subjected to larger ocean current force in the sea water, and the pile body is lifted only at the pile top, so that the state of the pile in the water is extremely unstable, and accidents such as the pile body crashes into a barge or the side turning of lifting equipment are greatly caused.
