ASTM F3033-16(R2021) pdf free download.Standard Practice for Installation of a Single-Sized, Cured-In-Place Liner Utilizing an Inflatable Bladder for Resurfacing Manhole Walls of Various Shapes and Sizes
1. Scope
1.1 This practice covers requirements for the cured-in-place rehabilitation of manholes without excavation, utilizing an inflatable bladder, and not limited to sanitary sewer manholes. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 There is no similar or equivalent ISO standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability of regulatory limitations prior to use. Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions—unless otherwise indicated, definitions are in accordance with Terminology F412, and abbreviations are in accordance with Terminology D1600. 3.2 Definitions ofTerms Specific to This Standard: 3.2.1 bonded—adhered to the manhole walls. 3.2.2 chimney—the upper portion of a manhole – including the corbel section, adjusting rings, and the frame/lid. 3.2.3 CIPMH—Cured-In-Place Manhole. 3.2.4 close-fitting—fitting tightly to the manhole walls. 3.2.5 compression seal—a gasket that forms a seal between the original manhole and the cured-in-place liner. 3.2.6 design engineer—a licensed professional engineer in the state where the installation is to take place. 3.2.7 freeze/thaw cycle—occurs when an area experiences fluctuations in a temperature range from 28 °F (-2.2 °C) to 50 °F (10 °C). 3.2.8 impermeable barrier—an air-tight corrosion resistant film formed when the inflation bladder is left behind perma- nently bonded to the interior of the cured-in-place manhole, when a compatible epoxy resin system is used.3.2.9 inflation bladder—is a single sized polymer based air-tight tube that is sized equal to or less than the smallest cross section of a manhole corbel area. Discussion—The bladder is subjected to a pressur- ized fluid. It expands and presses the liner against the walls of the manhole. 3.2.10 inflation device—a device that is outfitted with an inflation bladder that when inflated presses the liner tube against the manhole walls. 3.2.11 inflow and infiltration—the intrusion of extraneous water through a manhole. 3.2.12 glass reinforcing mat—a woven roving glass mat used to increase tensile strength in the upper corbel section for increased freeze/thaw resistance. 3.2.13 single sized liner—a textile liner tube that is con- structed having expansive properties, sufficient to stretch conforming to both the barrel and the corbel sections by the action of an inflation bladder. Discussion—In the upper corbel section the textile tube may overlap and provide a more substantial wall thickness, producing a cured in place liner that resists freeze/ thaw cycles.3.2.14 small voids—a crack in the manhole walls that is no greater than 1 ⁄ 2 in. (1.3 cm) along any dimension. 3.2.15 thermoset resin— polyester, vinyl ester, epoxy, or silicate resin systems being ambient, steam, or hot water cured. Discussion—The resin of choice is selected based upon the project criteria. Criteria 1– Resurfacing the interior surface of the host man- hole; use any of the four applicable resins listed above. Criteria 2– Elimination ofinfiltration and inflow; use any ofthe four resins listed above with the inclusion of the gaskets. Criteria 3– Resurfacing the interior surface ofthe host manhole and elimination of infiltration and inflow limited to the chimney section; use the silicate resin.
