Abstract (en)
[origin: EP0601948A1] Plugging device for the injection and the retention of a treatment product in a masonry wall, of the type comprising a slightly frustoconical elongate hollow body (1) which is provided at its rear end with a frustoconical flaring (10) and, over its entire length, with a series of flanges. The elongate hollow body (1) includes, at its rear part (11), a series of circular flanges (2) which are regularly spaced and have a diameter greater than that of the orifice into which the device is to be introduced, with the exception of the end flange (20) which has a diameter which is smaller than the others but is nevertheless slightly greater than that of the said orifice; and it includes, at its front part (12), a series of flanges (3, 4) which are either of oblong shape or are approximately cross-shaped with wide branches, alternate flanges of this latter series including, at the border of their front faces, at least two diametrically opposite collars (43) of substantially hemiellipsoidal shape. <IMAGE>
