ASTM C1885-23(Specification)
Standard Specification for Circular Precast Concrete Culvert, Storm Drain, and Sewer Pipe for Pipe Jacking

SCOPE
1.1 This specification covers the manufacturing requirements for circular concrete pipe that is intended to be installed using pipe jacking techniques. The typical use of this type of pipe is for the conveyance of sewage, industrial wastes, storm water, utilities, or personnel.  
1.2 The requirements of this specification are intended to supplement the existing manufacturing standards for precast concrete pipe and provide the additional manufacturing details required for pipe that will be installed using jacking techniques. The parent manufacturing standard for the concrete pipe is denoted as the “designated concrete pipe manufacturing standard” throughout this document. The requirements included within shall supplement the designated concrete pipe manufacturing standard when the concrete pipe is to be used for jacking.
Note 1: This specification is a manufacturing and purchase specification for concrete pipe installed using jacking techniques, to be utilized in conjunction with the designated concrete pipe manufacturing standard. It is possible that such pipe will require a special design to withstand the anticipated longitudinal loading. Additional calculations and information beyond what is required for a direct bury pipe are required to establish maximum jacking forces. For calculating allowable jacking forces, ASCE 27 may be referenced.
Note 2: This standard may be used to supplement existing standards for precast concrete pipe when the pipe will be installed using trenchless methods. Such “designated concrete pipe standards” include, but are not limited to: C14, C76, C361, C655, C985, C1417, C1765, and C1846/C1846M.  
1.3 There are many forms of pipe jacking. The most advanced of these, and in a category all its own, is microtunneling pipe. With the highly accurate guidance systems used in microtunneling, the pipes are utilized in longer push lengths and more challenging configurations and soil conditions. This standard does not address concrete pipe used for microtunneling. For concrete pipe used in microtunneling, the engineer, producer, and installer are encouraged to work together in establishing the specific needs of each project.  
1.4 There are applications where concrete pipe is utilized as a carrier pipe and is pushed through a casing after the soil has already been removed. These applications are not specifically addressed by this standard since the requirements for these types of installations differ from those for a typical jacking installation.  
1.5 Units—The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 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.

ASTM C1840/C1840M-22(Practice)
Standard Practice for Inspection and Acceptance of Installed Reinforced Concrete Culvert, Storm Drain, and Storm Sewer Pipe

SIGNIFICANCE AND USE
4.1 The inspection of installed reinforced concrete pipe verifies proper installation of the product and establishes thresholds for comparison further evaluation.  
4.2 This practice is useful as a reference by an owner in preparing project specifications and to identify, evaluate and interpret observations during post installation inspections of pipe.
SCOPE
1.1 This practice covers the requirements for inspection and acceptance of installed reinforced concrete pipe by either person-entry, or remote inspection as shown in Figs. 1 and 2, respectively.
FIG. 1 Person Entry Inspection  
FIG. 2 Remote Inspection Camera  
1.2 The scope of this specification is intended for installation related observations and assumes that pre-installation inspection has been completed.  
1.3 The reinforced concrete culvert, storm drain and storm sewer pipe shall be manufactured in accordance with Specification C76, C506, C507, C655, C1417, or C1846/C1846M and accepted in accordance with AASHTO R 73. This specification shall only be used for gravity, non-pressure storm drainage applications.  
1.4 Person Entry shall be used unless extenuating circumstances preclude this type inspection. Remote inspection is acceptable for use for pipe diameters of 30 in. [750 mm] and smaller unless otherwise specified by owner or engineer.  
1.5 Access of installed pipe for manual inspection shall follow OSHA 29 CFR PART 1926 SUBPART AA regulations for confined space entry. However, 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 and health practices and determine the applicability of regulatory limitations prior to use.  
1.6 This practice does not cover deformation or deflection assessment. Concrete pipe is classified as a rigid structure because they do not bend or deflect appreciably under load before cracking. Due to these facts shape evaluation are of little or no value when evaluating concrete pipe.  
1.7 The values stated in either Imperial/US or [SI units] are to be regarded separately as standard. The SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.  
1.8 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.
