Abstract

The present invention relates to a boring machine for pressurised chutes, said machine being provided with a valve and comprising: a ring, anchoring element (16), divided into at least two segments (18, 20) that may be coupled to cover the whole final joint (7B) of the valve (7) and to hold to the relieves (14) of said valve. The machine also comprises a flange (22) that must be set on the guiding head of the boring tool of the present machine (36) and that may be closed with the anchoring device (16). Finally, a ring seal (40) is also envisaged, said seal being set and closed between said flange (22) and the final joint (7B) of the valve (7) with the closure of said flange (22) with the anchoring device (16), in order to guarantee a stable sealing.
