The ship body is always occupied during cutting, and the time for cutting operation and hoisting is long, so that other tasks can not be performed during cutting.
Second kind: and (3) aiming at the ultrahigh steel pipe pile which does not affect the pile sinking of the subsequent steel pipe pile, the pile driving ship continues the pile sinking operation of the subsequent steel pipe pile, when the pile driving ship shifts to meet the safety spacing, the double-hook medium-sized crane ship is used for lifting the hanging basket to the position to be cut off in the conventional operation, and workers finish pile top hanging point tying and pipe pile redundant part cutting off in the hanging basket. The method is greatly influenced by wind waves, and medium-sized or above crane ships with strong wind wave resistance are required to be selected, so that the cost is high.
In addition, corbels are welded on the reserved section 2.1 of the pipe pile 2 and serve as a foundation of a cast-in-place concrete supporting system of the subsequent cross beam. The welding bracket is operated on an operation platform by mainly using a conventional operation cradle for hoisting a crane ship, so that the time of the ship body is further occupied.
