Specification for Tightness Testing of Environmental Engineering Concrete Containment Structures (ACI 350.1-10) and Commentary
|Publication Date:||1 January 2010|
Work specified-This Specification covers tightness testing of liquid and gaseous environmental containment structures designed to resist liquid or gaseous loads. Provisions of this Specification shall govern except where other provisions are specified in Contract Documents.
These test methods are for the tightness testing of concrete environmental engineering liquid and gaseous containment structures. The included tests are:
(a)Hydrostatic tightness test for open or covered containment structures.
(b)Surcharged hydrostatic tightness test for closed containment structures.
(c)Pneumatic tightness test for closed containment structures.
(d) Combination hydrostatic-pneumati
The tightness testing procedures and requirements contained herein are applicable to reservoirs, basins, and tanks constructed of concrete or a combination of concrete and other materials. Preparatory items indicated are required, unless otherwise specified, but the waiver of such items shall not change the test criteria.
Each cell of multi-cell containment structures shall be considered a single containment structure and tested individually unless otherwise permitted.
The hydrostatic tightness testing procedures and requirements herein are also applicable for tightness testing of open concrete liquid transmission structures such as castin- place concrete channels and conduits.
The hydrostatic tightness testing procedures and requirements herein, where applicable, can be used for tightness testing of concrete paved structures, such as channels and impoundments.
Work not specified-These provisions are not intended for hazardous material primary or secondary containment structures, cryogenic storage structures, highpressure gas tanks, or miscellaneous precast concrete structures such as culverts, pipes, and manholes.
