METHOD FOR INVERTING THE CONVEX CONFIGURATION OF A LIQUID-PRODUCT STORAGE-TANK BOTTOM

摘要

This invention relates to a method for inverting the convex configuration of a liquid-product storage-tank bottom with a view to providing greater efficiency in the operations of removing the undesirable materials which normally accumulate in the tank bottom (5). A layer of material having, plastic properties, is placed over the conventional tank bottom (7), except for one part from the centre of the tank base to the edges. The material with plastic properties hardens over time, thus producing a new bottom (7) whose centre (11) is at a level below the level of the edges. The part over which material having plastic properties was not placed forms a flow gutter (9) which leads the liquids and sediments which have to be drained off to the edges.
