Chapter
The term pipe jacking is used to describe an installation method as well as a concept that is fundamental to a number of trenchless techniques. It is important to differentiate between the principle and technique. Pipe jacking can be described as the principle of using hydraulic rams to push preformed sections to line the hole formed by a cutting h...
Chapter
The civil engineering industry is conservative. Today’s construction is engineered to be operational far into the future, and it is normal to design new installations with a 100-year working life. Fortunately, engineers working in the nineteenth century also held this view, and their utility systems still serve us. If utilities are to accept new id...
Chapter
Operators are faced with the difficult decision of determining when it is economical to use trenchless methods over conventional technology. Trenchless methods have been historically selected for the following reasons: 1. Restoration costs are high. 2. Municipal authorities prohibit the open-cut trenching of key streets or highways. 3. The right-of...
Chapter
Instrumentation systems are available for unguided and guided boring systems. For unguided boring systems, instrumentation can provide information on tool location, even though it is out of sight of the operator. Instrumentation is required to locate, track, and steer a guided system. In this chapter we discuss a number of different types of system...
Chapter
Three general methods for creating a hole for trenchless installation are described in Table 3-1: (1) compression/displacement, (2) percussion, and (3) cutting.
Chapter
The term trenchless technology is used to describe a wide array of technologies, processes, and techniques for creating holes or renovating conduits without disturbing the surface. This wide usage can create confusion for both the regular and prospective users in this rapidly advancing field. Trenchless technology, as addressed in this book, is the...
Chapter
The best way to illustrate the successful use of trenchless construction methods is by example. A selection of case histories is presented in this chapter to provide a cross section of the wide variety of equipment and applications encountered. The cases, illustrating successful and cost-effective applications, are taken from different operating en...

Chapter
Although guided horizontal boring was first utilized for pipeline underriver crossings in the early 1960s, small-diameter steerable horizontal boring was not adapted for more common utility and construction applications for another two decades because of the cost of hardware; lack of small, easy-to-use equipment and instrumentation; and lack of a b...

Chapter
A philosopher wrote, “The man who ventures to write contemporary history must expect to be attacked, both for everything he has said and everything he has not said” (Braude 1965). History provides a data bank of experiences, and if we take heed, we should be spared the futile but often popular pastime of reinventing the wheel. History also reveals...
Chapter
The trenchless technology project can be divided into the following tasks: (1) selection of trenchless equipment; (2) planning and design of project; (3) job implementation. The operator or contractor will have to evaluate the economic, technical, and often legal aspects of each of these tasks. In many projects, three parties will be involved: the...

Chapter
Increasingly, the utility engineer is faced with the problems of replacing, upgrading, or renovating the existing pipes and cables that lie beneath the streets of cities and towns. Over the last 20 years the emphasis has changed from that on new installation in previously unserved communities to rehabilitation of the existing infrastructure.

... Further investigation may be required to determine the cost and benefit of various trenchless technologies for a particular project. This paper does not plan to provide a detailed list of available trenchless technologies and their respective advantages, which can be found in other studies (e.g., Kramer 2012;Marchant 2019;Milligan and Rogers 2001). ...
... where L = length of pipe line (m), ω = pipe weight per unit length (kN/m), σ = normal stress on the pipe surface (kN/m 2 ), f = friction coefficient between pipe and soil (f = tan φ/2), c' = adhesion between pipe and soil (kN/m 2 ). Terzaghi (1943) after Thomson (1993) suggested that: ...
... According to Harbuck (2000), horizontal directional drilling (HDD) is preferred in many urban areas of the world due to three basic reasons: (1) the costs of restoring the surface in the case of open-cut are high, (2) the municipal authorities find it very inconvenient to perform open-cut in the congested areas and business districts, (3) the right-of-way is not accessible due to other structures that have been developed over the years. In the developed countries, it's the most common method used to surrogate the open-cut method for water supply installations in areas where the latter is not desirable or not acceptable (Najafi & Gokhale, 2005). ...
... Cured-in-place linings and pipes (CIPLs and CIPPs, respectively) are reinforced polymer linings installed remotely inside existing underground pipelines and conduits with minimum environmental disturbance through trenchless construction procedures (e.g., Ampiah et al. 2010;Brown et al. 2014;Kramer et al. 1992). Although these cured-in-place systems are used primarily to rehabilitate underground lifelines for daily use, they also allow for in situ retrofitting of underground utilities against earthquake-induced transient and permanent ground deformation (Zhong et al. 2017a, b;Bouziou 2015;Zhong 2014;Bouziou et al. 2012). ...
