[0033] Working principle:

[0034] Step 1: After the steel beam construction is completed, remove the bottom seat and adjustment block of the steel beam by cutting or lifting with a jack.

[0035] Step 2: Weld temporary lifting lugs, use hand winch to lift the distribution beam, and then use this tool to cut the connection between the distribution beam and the steel pipe column. Just put this tool on the steel pipe column, and then use the reel 2 to control the annular drive 5 and the flame cutting assembly 4 to move to the cutting position and then cut.

[0036] Step 3: Remove the connection system between the steel beams.

[0037] Step 4: Use a floating crane to pull out piles. If the floating crane cannot pull out piles, use underwater cutting. Similarly, just move the tool to the position where the steel beam needs to be cut, and cut the steel pipe piles underwater at the riverbed. The cut steel pipe piles are temporarily stabilized by a ship and transported by ship after cutting.
