Abstract
Abstract An environment protecting dike assembly is disclosed comprising interlocking, plastic, wall shaped components which can be erected as a dike wall around storage tanks or other liquid containing vessels. The components of the assembly are of modular construction, permitting dikes of different configuration and size to be constructed. When erected on a liquid impermeable substratum such as earth covered with plastic sheeting, the assembly forms an effective liquid barrier, preventing liquids contained within the assembly from escaping, as, for example, in the event of a storage tank rupture.

Claim 3
Dependent Claim
26 words
A dike assembly according to claim 1 in which said strut and corner member components, and said strut member couplers are fabricated from fiberglass reinforced plastic.
Claim 4
Dependent Claim
52 words
A portable dike assembly assording to claim 1 in which said fastening means comprise anchor members inserted into the substratum through holes in flanges forming a part of said strut and corner member components, and said strut member couplers, and said substratum is covered with a substantially liquid impermeable layer of plastic.
Claim 5
Dependent Claim
53 words
A dike assembly according to claim 3 in which said plastic layer is placed between the top of said flanges and the bottom of sealing bars, and held in that position by anchor members passed through said sealing bars, plastic layer, and flanges, into said substratum, thereby forming a substantially liquid impermeable seal.
