13、MANUALS AND REPORTS ONENGINEERING PRACTICE(As developed by the ASCE Technical Procedures Committee, July 1930,and revised March 1935, February 1962, and April 1982)A manual or report in this series consists of an orderly presentation offacts on a particular subject, supplemented by an analysis of li

14、mitationsand applications of these facts. It contains information useful to the averageengineer in his or her everyday work, rather than ndings that may beuseful only occasionally or rarely. It is not in any sense a “standard,”however; nor is it so elementary or so conclusive as to provide a “rule o

15、fthumb” for nonengineers.Furthermore, material in this series, in distinction from a paper (whichexpresses only one persons observations or opinions), is the work of acommittee or group selected to assemble and express information on aspecic topic. As often as practicable the committee is under the

16、directionof one or more of the Technical Divisions and Councils, and the productevolved has been subjected to review by the Executive Committee of theDivision or Council. As a step in the process of this review, proposedmanuscripts are often brought before the members of the TechnicalDivisions and C

17、ouncils for comment, which may serve as the basis forimprovement. When published, each work shows the names of thecommittees by which it was compiled and indicates clearly the severalprocesses through which it has passed in review, so that its merit may bedenitely understood.In February 1962 (and re

18、vised in April 1982), the Board of Directionvoted to establish a series titled “Manuals and Reports on EngineeringPractice,” to include the Manuals published and authorized to date, futureManuals of Professional Practice, and Reports on Engineering Practice. Allsuch Manual or Report material of the

19、Society would have been refereed ina manner approved by the Board Committee on Publications and would bebound, with applicable discussion, in books similar to past Manuals.Numbering would be consecutive and would be a continuation of presentManual numbers.

The pipelines arethe infrastructure that prov

34、ides our homes, our ofce buildings, ourschools, and other structures with waste removal via sanitary sewers,stormwater drainage, potable water, gas, recycled water, irrigation, elec-tricity, communication, and cable TV (as listed in order of most commoncurrent usage).These pipelines can be installed

35、 by a variety of construction methods,with the most common being open trench excavation. The pipelines can befound anywhere, but are typically installed within the rights-of-way of ourroads, streets, and highways. As new pipelines are installed below thesurface and more utilities are abandoned, the

36、density of the undergroundinfrastructure increases. As the amount of trafc increases on the roadsurfaces, access to the subsurface also decreases. Installing new infrastruc-ture and pipelines within an existing right-of-way has become moredifcult. However, not all pipelines can be installed by open

37、trenchexcavation. The pipeline industry has adopted and now offers increasinglysophisticated solutions to meet the challenges of installing pipelines incongested, urban environments around the world. Because these newconstruction solutions/methods do not rely on digging a trench, themethods are know

38、n as trenchless methods.Some of the more widely used trenchless methods for new utilityinstallations are (as listed alphabetically)Guided boring through nondisplaceable soils or rock;Guided boring using a pilot tube;Horizontal auger boring;Horizontal directional drilling (HDD);1Impact moling;Microtu

39、nneling;Pipe jacking;Pipe ramming; andUtility tunneling.Trenchless methods are often attractive to project owners and oftenrequired by regulatory agencies and property owners because they gener-ally result in fewer impacts to the surface, existing structures, and infra-structurethandotraditionalopen

40、trench excavations.Abovegroundeffectsare reducedbecauseonlyshafts,pits, or portals have to beexcavated ratherthan a continuous trench. Underground impacts are reduced because thepipe can be installed without excavating the otherwise conicting under-ground utilities or surface structures. The applica

41、tion of certain trenchlessmethodsenablesalignmentcontrolinestablishedcorridorsandrights-of-waythat are becoming more congested. In general, the benets of trenchlessconstruction methods can be summarized as follows:Safer for the public;Lowers social and economic effects;Minimizes environmental effect

42、s including carbon footprint;Reduces trafc effects;Allows for deeper installations without signicant increases in thecost;Mitigates impacts to existing surface and subsurface infrastructure;Addresses potentially challenging subsurface conditions such as softor loose soil, rock, or the groundwater ta

43、ble;Allows more freedom in alignment selection within or outside ofestablished rights-of-way; andReduces project duration or work content.Trenchless design is much more sensitive to subsurface conditions thanopen trench excavation. It is usually more difcult, costly, and time-consuming to adapt tren

44、chless methods to unexpected ground conditionsthanitistoadaptopentrenchexcavations;primarilybecausewhentrenchlessmethods are used, the material being excavated is not visible or directlyaccessible. When using trenchless methods, it is critical to conduct athorough geotechnical and subsurface investi

45、gation to determine, amongotherthings,geology,groundtypeandanticipatedbehavior,groundwater,and the presence of buried objects placed naturally or as a remnant of pastconstruction.Theanticipatedconditionsaffecttheselectionofthetrenchlessmethod, the design layout, and even the contract provisions.The

46、basic design process for a trenchless project should include identi-fying and understanding project requirements, owner design require-ments, third-party requirements, ground conditions, and risks and risk2 PILOT TUBE AND OTHER GUIDED BORING METHODStolerance. This information is then used in the des

47、ign phase to select themost suitable trenchless method; provide a well-thought-out design thatminimizes the risks; mitigate the controllable risks; identify potentialclaims and address them; and prepare contract clauses that help allocaterisks and manage disputes.The decision to use a trenchless met

48、hod, and the selection of a particularmethod from those available, should be made methodically and systemat-ically and be based on project requirements. Trenchless methods, equip-ment, and guidance systems have improved and changed over time, andcontractors have continued to apply innovative new tec

49、hniques to con-struction. Therefore, it is important for design engineers to remain currentwith all available trenchless methods to systematically evaluate options.Regardless of the trenchless method selected, adherence to the followingguidelines can reduce project cost, schedule, and risk:Use uniform outside diameters (ODs) to the extent possible;Use similar drive lengths to the extent possible;Keep drive lengths within practical limits;Minimize the number of shafts;Locate shafts at typical maintenance access points; andEvaluate alternative alignm
