Method for producing a leak-proofing lining on an existing, single-walled steel tank, and tank produced according to the method

摘要

In this method, which is suitable specifically for rehabilitating tanks installed in the ground, the individual sheets (23, 29, 31) for producing the leak-proofing lining are introduced through the manhole (5) of the existing steel tank (1) and are fitted together there. Lugs (22) or spacer plates (33) serve for forming a gap (17) between the leak-proofing lining forming a second tank (11) and the existing steel tank (1). A tank produced in this manner can be equipped with a leak-proofing device. IMAGE
