<p>PURPOSE:To let relative intervals be maintained without restraining a laying main body from being moved in the axial direction, and thereby prevent it from being damaged by using a spacer means composed of a spacer in a clamp form held by the under water laying main body, and of a connecting member in a string form. CONSTITUTION:A spacer 18 in a clamp form is provided wherein two pieces divided type half clamps 24A and 24B held by a laying article 16 are monolithically formed with circumferential face members 26A and 26B the outer diameter D2 of which is equal to or more than that two times as large as the outer diameter D1 of a laying article main body 16. Then, the spacer 18 adjacent to one another are connected with connecting members 20 in a string form so that a spacer means 14 is formed. And intervals between the laying article main bodies 16 are set up by the spacer 18 and the connecting members 20, contact is made only by the adjacent spacer 18, and moreover, the spacer 18 is relatively free in movement. And the laying article main body 16 is so designed not to be subjected to violent load, even if a floating body is tilted by a pitching motion.</p> |
