Abstract
A fluid retaining structure comprising an electronic leak detection and location, ELDL, system, wherein the fluid retaining structure comprises inner and outer liners (18, 16) that form electrical isolation layers of the ELDL system, wherein an electrically conductive signal layer (10, 12) of the ELDL system provides structural rigidity to the fluid retaining structure.
Claims17
A fluid retaining structure having an electronic leak detection and location (ELDL) system, the fluid retaining structure comprising:
- electrically non-conductive inner and outer liners adapted to form electrical isolation layers for the ELDL system;
- and
- an electrically conductive signal layer located between the inner and outer liners;
- wherein
- the inner and outer liners create an environment, within an interstitial space between the inner and outer liners, that is (a) electrically isolated from an outside of the fluid retaining structure and (b) electrically isolated from an internal environment inside the fluid retaining structure,
- the electrically conductive signal layer is configured to provide structural rigidity to the fluid retaining structure,
- the electrically conductive signal layer is made of a concrete-based material with steel reinforcement;
- and wherein the outer liner is welded to the inner liner such that the outer liner passes through a wall-roof joint of the electrically conductive signal layer.
A method of retaining a fluid in a structure with an electronic leak detection and location (ELDL) system, comprising:
- providing electrically non-conductive inner and outer liners to act as electrical isolation layers for the ELDL system;
- placing an electrically conductive signal layer between the inner and outer liners, the electrically conductive signal layer being configured to provide structural rigidity for the fluid retaining structure;
- and
- retaining the fluid inside the inner liner of the ELDL system,
- wherein
- the inner and outer liners create an environment, within an interstitial space between the inner and outer liners, that is (a) electrically isolated from the outside of the fluid retaining structure and (b) electrically isolated from an internal environment inside the fluid retaining structure,
- the electronically conductive signal layer is made of a concrete-based material with steel reinforcement;
- and wherein the outer liner is welded to the inner liner such that the outer liner passes through a wall-roof joint of the electrically conductive signal layer.
A kit of parts for a fluid retaining structure having an electronic leak detection and location (ELDL) system, comprising:
- electrically non-conductive inner and outer liners adapted for forming electrical isolation layers for the ELDL system;
- and
- an electrically conductive signal layer to place between the inner and outer liners, the electrically conductive signal layer being configured to provide structural rigidity to the fluid retaining structure,
- wherein
- the inner and outer liners create an environment, within an interstitial space between the inner and outer liners, that is (a) electrically isolated from the outside of the fluid retaining structure and (b) electrically isolated from an internal environment inside the fluid retaining structure,
- the electronically conductive signal layer is made of a concrete-based material with steel reinforcement;
- and wherein the outer liner is welded to the inner liner such that the outer liner passes through a wall-roof joint of the electrically conductive signal layer.
