Title: SYSTEM FOR CONTAINING SPILLAGES FROM A TUBE TRANSPORTING FLUID OR MUD ACROSS DISTANCES OF SEVERAL KILOMETRES
Abstract:
The invention relates to a system for containing spillages from a tube (20) transporting fluid or mud across distances of several kilometres, in the mining, oil and/or sanitation industries, for containing a leaked fluid at a pressure in the order of atmospheric pressure, which system comprises modular chambers (11, 11') arranged in a chain or series along the tube (20), wherein each modular chamber (11, 11') is arranged around a corresponding section of the tube and comprises an upper module and a lower module which are complementary, for surrounding the tube, each module having a surrounding of plastic material and containing a filling material (7) that constitutes a porous medium, such that the leaked fluid or a portion of same, which enters through a perforation made by the tube breaking in the surrounding, can flow through the filling material (7). According to the invention, each upper module is in fluid communication with the lower module of the same modular chamber by run-off means, so that when a break in the tube projects the fluid inside the upper module, the liquid can run towards the lower module, each modular chamber being in fluid connection with contiguous modular chambers by means of flexible tubes (13) connected between the corresponding lower modules to allow evacuation by means of overflow, the upper module comprising a ventilation outlet (12) to evacuate a volume of air.
