The invention relates to an adjustable support particularly suitable for underwater pipe lying a substantial distance from the sea bed. The structure of the support is simpler and is easier to manuever than known structures, and includes two parts. The lower part has a tubular frame with a square or rectangular base provided with four slidable vertical legs of variable length carrying support plates at their lower ends which are adaptable to the slope of the sea bed. The upper part has a slab on which there is disposed a fixed half saddle with its upper part in the form of a hook, and a slidable half saddle which, by means of release and locking devices, can be brought into contact with the fixed half saddle to form a semicircular support base for the pipe. The upper and lower parts of the support are connected together by means of two hydraulic jacks and four inclined telescopic legs; it being possible to insert, between the support base for the jacks and inclined telescopic legs and the lower part, grid structures of greater or lesser height depending on the distance of the pipe from the sea bed. |
