Abstract (en)
[origin: EP0405520A1] The invention relates to a method of making preferably cylindrical, hollow structural bodies, in particular shafts, which as a rule are used for irrigation or drainage, as an inspection part or for the installation of fittings, a water-tight plate (12) being produced at the works, which plate (12) is assembled together with a water-tight basic body (14) likewise at the works. The basic body (14) is preferably provided with recesses (114) and/or openings, in the course of which, during assembly of these parts at the works, a gap (16) which arises is grouted with material for joints resistant to tension and compression, and a sealing gap (18) which arises is sealed off with a permanently elastic material. <IMAGE>
