To provide a net stretching method having high workability and versatility and enabling an operator to easily and safely stretch a net with a relatively small number of materials without entering a cylindrical structure.SOLUTION: A net N is disposed outside an opening Z. The rear ends A2, A2 of ropes A, A exposed through the opening Z are locked to ring members R2, R4 attached to the corners of the front edge N1 side of the net N. The front ends B1, B1 of ropes B,B exposed through the opening Z are locked to ring members R1, R3 attached to the corners of the rear edge N2 side of the net N. The net N deformed so as to pass through the opening Z is received through the opening Z in a cylindrical structure 1. Then, the front ends A1, A1 of the ropes A, A exposed from through-holes X2, Y2 to the outside of a front wall W1 and the rear ends B2, B2 of the ropes B, B exposed from through-holes X1, Y1 to the outside of a rear wall W2 are respectively pulled in a direction away from the outside of a peripheral wall W, and the net N is spread in a space S.SELECTED DRAWING: Figure 8
【課題】筒状構造物内に作業者が入ることなく、比較的少ない資材で容易且つ安全にネットを張設することができ、作業性及び汎用性にも優れたネット張設方法を提供する。【解決手段】開口部Ｚの外側にネットＮを配備し、ネットＮの前縁部Ｎ１側の角隅部に取り付けられたリング部材Ｒ２，Ｒ４に、開口部Ｚから露出したロープＡ，Ａの後端部Ａ２，Ａ２を係止し、ネットＮの後縁部Ｎ２側の角隅部に取り付けられたリング部材Ｒ１，Ｒ３に、開口部Ｚから露出したロープＢ，Ｂの前端部Ｂ１，Ｂ１を係止し、開口部Ｚ内を通過可能な状態に変形させたネットＮを、開口部Ｚを経由して筒状構造物１内に収容した後、貫通孔Ｘ２，Ｙ２から前壁部Ｗ１外に露出するロープＡ，Ａの前端部Ａ１，Ａ１側、並びに、貫通孔Ｘ１，Ｙ１から後壁部Ｗ２外に露出するロープＢ，Ｂの後端部Ｂ２，Ｂ２側を、それぞれ周壁Ｗ外から離れる方向へ引っ張り、空間Ｓ内にてネットＮを広げる。【選択図】図８
