<p>PROBLEM TO BE SOLVED: To accurately seat an intake of a seawater intake pipe on a sea bottom seating point, smoothly pumping up seawater, prevent a collapse of the seawater intake pipe at piping time, and prevent the useless excess length from appearing in the seawater intake pipe. SOLUTION: This pipe laying method of the seawater intake pipe 1 lays the seawater intake pipe 1 on the sea bottom between a land side landing point 7 and a sea side sea bottom seating point. A laying barge 2 mounted with the seawater intake pipe 1 is stopped in an oversea position 7A near the landing point 7. After delivering and laying the seawater intake pipe 1 thereby up to the landing point 7 while pressurizing the seawater intake pipe 1 by fluid from the inside, the laying barge 2 is sailed up to the sea side sea bottom seating point or the oversea position in the vicinity, and the seawater intake pipe 1 is thereby similarly delivered and laid while pressurizing the seawater intake pipe 1 by the fluid from the inside. The intake side of the seawater intake pipe 1 removed from the laying barge 2 is precipitated up to the sea bottom seating point in a state of opening the intake in the sea side oversea position, and the seawater intake pipe 1 is laid.</p> |
