Method for manufacturing a transportable tray collection, as precast concrete, to collect liquids which might contaminate the waters.

摘要

The invention relates to a process for producing a CUBETA CATCHER (1) PREFABRICATED CONCRETE FOR LIQUIDS PORTABLE WATER POLLUTANTS, where CATCHER (1) CUBETA It is made into a negative ENCOFRADO (3). The new procedure is characterized by the STEPS: STRIP CHAPA CONTINUOUS (21) CAPA sealingly SIDE IN THE PLANE OF SIDE WALL WITHOUT CONTACT WITH MOLD (3), the upper edge of the metal strip (21) with a FRESH CONCRETE WITH SETTING DELAYED, FRESH CONCRETE STANDING PANEL PLATE (20) and along its edge (20 '') is welded to a sheet metal strip (21) to form a CUBETA device (2) Fresh Concrete Compressive and embedding CUVET device (2), WHERE THE DELAY SETTING OF FRESH CONCRETE IS ADJUSTED SO THAT THIS SIMULTANEOUSLY FORGE WITH FRESH CONCRETE SUBSEQUENTLY PLACED.
