Pipe jacking is a construction process for the no-dig laying of pipes. Successful pipe jacking demands low skin friction between the ground and the jacked pipe. This is achieved with bentonite lubrication. The bentonite slurry fed into the annular gap fulfils several purposes. It stabilises the annular gap by supporting the surrounding ground and reduces friction contact between ground and jacked pipe. The Bentonite Handbook deals comprehensibly with the relevant aspects of annular gap lubrication: starting with the ground conditions, which are of decisive importance for lubrication, through the rheological properties of the bentonite slurry to the technical components of lubrication technology and lubrication strategy. The use of standardised measuring apparatus is described as well as mixing equipment and the automatic lubrication system. Overview tables with calculations and suggested values for bentonite consumption quantities depending on the prevailing ground conditions and the pipe jacking parameters complete the recommendations.

Abstract: The book deals with almost all aspects of annular gap lubrication in pipe jacking - from ground conditions, through the properties of bentonite to the technical aspects. There is also a collection of calculations and suggested values for bentonite consumption quantities.

Civil works for hydroelectric facilities: guidelines for life extension and upgrade
Author(s)/Editor(s): ASCE Hydropower Task Committee | Size: 26 MB | Format:PDF | Quality:Scanner | Publisher: American Society of Civil Engineers (ASCE) | Year: 2016 | pages: 490 | ISBN: 0-7844-0923-4
''Civil Works for Hydroelectric Facilities: Guidelines for Life Extension and Upgrade'' explores methodologies and techniques for applying rehabilitation engineering to aging hydroelectric infrastructure. This report provides guidelines for life extension and upgrade of hydroelectric works for use by owners, operators, regulators, and engineers considering infrastructure rehabilitation or replacement. Presented by the Hydropower Task Committee of ASCE's Energy Division, this book features relevant case studies that illustrate solutions for improving the performance and extending the service life of civil works of dams and hydroelectric plants.

The "EAU 2012" takes into account the new generation of standards, which is shortly to be introduced into the building control system; it consists of Eurocode 7, the associated national application documents and additional national regulations (DIN 1054:2010). In certain cases, partial safety factors are determined differently based on experience in practice. This means that the safety standard of sea and port buildings remains in place; the recommendations nevertheless satisfy the requirements for international recognition and application regarding the planning, design, specification, tender procedure, construction and monitoring, as well as the handover of - and cost accounting for - port and waterway systems under uniform criteria.

Fire safety is a fundamental requirement of any building, and is of concern to several professions which contribute to the construction process. Following on from the success of the previous three editions, Paul Stollard has returned to update and expand this classic introduction to the theoretical basis of fire-safety engineering and risk assessment.
Avoiding complex calculations and specifications, Fire From First Principles is written with architects, building control officers and other construction professionals without fire engineering backgrounds in mind. By tackling an overview of the factors which contribute to fire risk, and how building design can limit these, the reader will gain a fuller understanding of the science behind fire regulations, safe design, and construction solutions.
All regulations content is fully updated, and has been expanded to cover the USA and China as well as the UK. Ideal for students of architecture and construction subjects, as well as practitioners from all built environment fields learning about fire safety for the first time.
