Page 16 - Trenchless Technology Piping Installation and Inspection

Preface

his book complements another title, Trenchless Technology:
Pipeline and Utility Design, Construction, and Renewal, published
Tby McGraw-Hill and WEF Press in 2005. The main idea for
this book came from a series of trenchless techno logy operator and
inspector training schools the author has offered since 1998. The
need for proper planning and partnering among owners, engineers,
and contractors in design, contract and project execution is especially
critical in trenchless technology projects where many uncertainties
are involved. However, development of new equipment and methods
and increased level of equipment sophistication and capabilities is
not a substitute for experience and training of operators and field
personnel, even it has increased this need. A safe and successful
trenchless project depends on skills, training, and experience of
operators, field personnel, and project inspectors. The main objec-
tive of this book is to highlight some critical aspects of trenchless
installation and inspection, and provide conceptual guidelines for
proper execution and quality control of these projects. This book
will be of use for all parties in a trenchless project as it provides
planning, design and construction, inspection, and project manage-
ment concepts.
Chapter 1 begins with an overview of buried pipe history, pipe-
soil interaction, and continues with comparison of open-cut and
trenchless method of pipe installation. A description of trenchless
installation methods, including conventional pipe jacking, utility
tunneling, horizontal earth boring (horizontal auger boring, horizon-
tal directional drilling, microtunneling, pilot-tube microtunneling,
and pipe ramming), are included. An important part of this chapter
includes characteristics and applications, including capabilities and
limitations for trenchless installation methods. This information will
be helpful to utility owners and design and consulting engineers to
properly select appropriate trenchless installation methods based on
their project specifics and site conditions. This chapter concludes
with a summary of safety considerations and potential risks/impacts
to pavements and adjacent utilities.
