Expansion Device For Containing Overflows

Abstract

An expansion device for containing overflows of watercourses, floods and / or inundations and like phenomena, suitable for cooperating with further identical expansion devices for making barriers for containing overflows of watercourses, floods and / or inundations and like phenomena, comprises an enclosure suitable for allowing the water permeability through said enclosure and an expanding and absorbing material inside said enclosure and suitable for increasing in volume following the absorption of water.

Description

FIELD OF THE INVENTION[0001]The object of the present invention is an expansion device for containing overflows of watercourses, floods and / or inundations and like phenomena, suitable for cooperating with further identical expansion devices for forming barriers for the containment of overflows of watercourses, floods and / or inundations and like phenomena; moreover, the present invention generally relates to the arrangement of expansion devices for the control and containment of watercourses and / or flows, as in the case of overflows of watercourses, floods and / or inundations and like phenomena.BACKGROUND OF THE INVENTION[0002]When floods or overflows of watercourses occur, barriers, walls, banks and similar containment system is made up of bags filled with sand.[0003]Bags and sand are separately carried to the site of use, then the bags are filled with sand and arranged in the desired position or optionally, bags already filled with sand are carried to the site of use and are arrange...

AI Technical Summary

Benefits of technology

[0006]The object of the present invention is to provide an expansion device for containing overflows and like phenomena, suitable for cooperating with further identical expansion devices for forming barriers for containing overflows, which should be easy to carry, handy and storable and should allow making an effective barrier for containing overflows and like phenomena.

Problems solved by technology

The procedures described provide for the transport of bags and sands, or of bags already filled, by lorry and both require difficult operations for the preliminary arrangement of the bags themselves, or their filling, or in any case the transport of the bags themselves once filled with sand.

This is a very expensive and difficult procedure from the point of view of manual operations to carry out, since the sand bags are very heavy and cumbersome, both in the transport to the emergency site, and in their use during the making of the containment barriers and finally, in their disposal, since wet sand is heavier than dry sand.
