Spill containment system and soft crossing device

Abstract

A reusable liquid containment system to capture and control spills or run-offs of hazardous liquids. The containment system consists of a reusable berm device which forms a perimeter dimension and conforms to various terrain elevations. The berm device consists of uniform elongated rectangular shaped foam units having an elastic memory, a rigid base, all encased in a fluid resistant protective cover with grommet protected openings to provide for horizontal and vertical connection. The berm devices are positioned in a single or multiple course to achieve appropriate elevation, with tapered berm devices to address varying topographic elevations. The containment system also consists of a draped containment liner or woven, knitted or braided fabric, or thermo-plastic material. The containment system allows wheeled vehicles and related equipment to cross without compromising the integrity of the perimeter berm and liner.

Description

[0001]The following Utility Patent Application Specification is hereby submitted by the named inventors as a non-provisional utility application following the filing of a Provisional Utility Patent Application on Jul. 9, 2012, Application No. 61 / 669,172.FIELD OF INVENTION[0002]This invention generally relates to the field of devices used to contain liquids, and especially such devices used as a secondary containment system to capture and control spills or run-offs of hazardous liquids and other substances which are dangerous to the environment. More particularly, this invention relates to such devices which provide a portable, transportable and reusable berm device and containment liner to accommodate a potential hazardous spill and which can be assembled in a quick and easy manner forming a containment barrier of a desired perimeter dimension and adaptable to various terrain elevations experienced in the field. Further, this invention relates to devices which permit wheeled vehicle...

Benefits of technology

[0009]The present invention, as described below, addresses the shortcomings of the prior confinement systems by providing a portable, easily configurable, economic, re-usable and transportable berm device...

Problems solved by technology

As a practical matter, most work sites do not have a permanent spill containment system in place at the time of the initial construction.

While many sites are graded prior to installation of such containment systems, many times such grading is inferior, not level, or the surface issues require height variations not know until the time of installation.

However, all previous attempts fail to address the height and grade variations necessary to construct and efficient and workable containment system.

In addition, the ability to recycle the berm material, as well as other economic and safety considerations, hav...
