METHOD AND APPARATUS FOR BLOCKING PIPES |
摘要 |
<p>Apparatus for blocking the bore of a pipe (1) comprises a plurality of elongate shutter members (15-17) pivotably mounted to an elongate support member (3/3a) for insertion through a pre-drilled aperture (8) in the pipe wall. Actuating means (14) are provided for pivoting the shutter members (15-17) from an insertion configuration in which they are substantially aligned with said support member (3a) and a deployed configuration in which they are fanned out across the bore of the pipe (1). Each shutter member (15-17) is pivoted about a point (9) located towards one end thereof and towards the insertion end of the support member (3a) so as in use to lie between the axis of the bore of the pipe and the wall of the pipe (1) opposite the location of said aperture.</p> |
