1.1 This specification covers the manufacturing requirements for precast reinforced concrete monolithic box sections that are intended to be installed using jacking techniques. The typical use of this type of product is for the construction of culverts and for the conveyance of storm water, industrial wastes and sewage.
1.2 The requirements of this specification are intended to supplement the existing manufacturing standards for precast reinforced concrete box sections and provide the additional manufacturing details required for box sections that will be installed using jacking techniques. The parent manufacturing standard for the precast reinforced concrete box sections is denoted as the “designated precast reinforced concrete box section manufacturing standard” throughout this document. The requirements included within shall supplement and supersede the designated precast reinforced concrete box section manufacturing standard when the box sections are to be used for jacking.
Note 1: This specification is a manufacturing and purchase specification for precast reinforced concrete box sections installed using jacking techniques, to be utilized in conjunction with the designated precast reinforced concrete box section manufacturing standard. It is possible that such box sections will require a special design to withstand the anticipated longitudinal loading. Additional calculations and information beyond what are required for a non-jacked installed box section are required to establish maximum jacking forces. For calculating allowable jacking forces, ASCE 28 may be referenced.
Note 2: This standard may be used to supplement existing standards for precast reinforced concrete box sections when the box sections will be installed using trenchless methods. Such “designated precast reinforced concrete box section manufacturing standards” include, but are not limited, to ASTM C1433, ASTM C1577, and AASHTO M259.
1.3 Units—The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
