SLURRY SCATTERING PREVENTION DEVICE FOR SLURRY PUMPING TRANSPORT PIPE
To provide such a neat appearance that normally a sheet material is in close contact with a transport pipe as much as possible, while slurry such as ready-mixed concrete is prevented from scattering by reducing the impact when the transport pipe bursts.SOLUTION: After a sheet material 3 is wrapped around a transport pipe 2 to cover it, the transport pipe 2 is fixed with fastening belts 5 at a plurality of locations spaced apart at regular intervals in the pipe axis direction. Fixing of the fastening belts 5 at this time is performed by a method/mode in which after forming a ring state C1 with a circumference sufficiently longer than the outer circumference of the transport pipe 2 and fixing it with a buckle portion 8, a part of the ring C1 is short-circuited to form a ring state C2 with a shorter circumferential length, and fixed with a binding band 11 so as to maintain this state. When a force is applied to the fastening belt 5 in this state in a direction to expand the diameter of the ring C2, when the fixed limit is exceeded, the binding band 11 breaks before being fixed by the buckle portion 8, and the diameter of the fastening belt 5 expands from the ring state C2 to the ring state C1.SELECTED DRAWING: Figure 5
【課題】通常時はシート材が輸送管に可及的に密着してすっきりした外観を呈する一方、輸送管破裂時にはその衝撃を緩和して生コン等のスラリーの飛散を防止する。【解決手段】シート材３を輸送管２に巻き付けて被覆した後、輸送管２の管軸方向に沿って一定間隔を置いた複数箇所を締結ベルト５で固定する。このときの締結ベルト５の固定は、輸送管２の外周長より十分に長い周長の円環状態Ｃ１を形成してバックル部８で固定した上で、その円環Ｃ１の一部を短絡させてより周長の短い円環状態Ｃ２を形成し、この状態を維持するように結束バンド１１で固定するという方法・態様で行う。この状態の締結ベルト５に対してその円環Ｃ２を拡径させる方向に力を作用させてゆくと、一定限度を超えたときに、バックル部８による固定よりも先に結束バンド１１が破断して、締結ベルト５が円環状態Ｃ２から円環状態Ｃ１に拡径するようになっている。【選択図】図５
