Rock Grouting by Friedrich-Karl Ewert Pdf

Fifteen years have passed since I was working at a dam site super vising grouting work. That was not the first time that I had to car ry out engineering geological investigations for several similar projects, which always included testing programmes to find out the permeability of the rock, and often I was in charge of grouting work. It thus attracted my attention when this particular grouting programme did not run as intended: most of the grout holes took only very little grout! It could not be the aim of the invested work simply to drill holes and fill them again without bringing about any further improvement. Fortunately, I had the chance to be en gaged in many other grouting programmes in the following years and used all these examples to analyse as thoroughly as possible the permeability of the rocks being treated in view of their grout ability. The more I studied, the stronger my conviction grew that our rules which had decided the grouting of rock for many de cades should be developed further, and therefore I occupied my self with contributing some ideas for a new basis to investigation and judgment of permeability of rock and for a more adequate application of this technology.

Rock Grouting at Dam Sites by Friedrich-Karl Ewert,Ulrich Hungsberg Pdf

This book focuses on the permeability of the foundation of dams, how to determine their state and how to tighten permeable rock to achieve safe foundations for large dams. It includes theoretical fundamentals as well as lessons learned in their application in practical construction work in eminent projects. It also discusses aspects such as the permeability of the rock mass at the dam site, including the hydraulic characteristics of water conducting openings and their effect on the reliability of water pressure test (WPT) results; the influence of particular geological factors on the hydrogeological regime at the site, as well as the hydrofracturing behavior and individual groutability; and the relationship between quantities of grout takes and the degree of impermeabilization.

Rock Grouting and Diaphragm Wall Construction by J. Verfel Pdf

The foundation of structures and the construction of underground railways in urban areas would be impossible without the use of diaphragm walls, grouting, anchors, micropiles, slender retaining walls, etc. Based on the author's own experience and taking into account the findings of various other authors, this book explains these methods in an intelligible manner, enabling the reader to judge for himself their suitability in construction practice.The aim of the book is to instruct experts in the correct application of grouting methods, and the correct choice of drilling systems and tools. It provides mainly practical information, and describes the most suitable, up-to-date technology available. Grouting applications in Czechoslovakia and abroad are illustrated by a series of practical examples.The book is designed for students of civil engineering faculties specializing in structural foundation, specialists of building companies, and experts in structural foundation. It will also be appreciated by experts in underground railway and tunnel construction, in structural engineering and urban development (landslides), as well as by manufacturers of the respective technology.

Practical Guide to Grouting of Underground Structures by Raymond W. Henn Pdf

Practical Guide to Grouting of Underground Structures presents a hands-on discussion of grouting fundamentals and provides a foundation for the development of practical specifications and field procedures. Employing a pragmatic approach to the subject of grouting, Raymond W. Henn concentrates on areas such as the types of drilling, mixing and pumping equipment, and their application. The book focuses on how cementitious grouting is used in conjunction with the excavation and lining of tunnels, shafts, and underground caverns in rock. Overviews of cementitious grouting in soils and chemical grouting are also provided. Topics covered range from record keeping to quality control and testing requirements, field operations, and production rates. Practical Guide to Grouting of Underground Structures is written as a useful handbook for engineers, construction supervisors, inspectors, and other professionals involved in the planning, design, and implementation of underground grouting programs.

Grouting Theory and Practice by E. Nonveiller Pdf

Grouting is a construction process by means of which the highly erratic permeability and deformability of foundation rock and soil are homogenized. The main parameter governing the design and construction of grouting works is the permeability of the rock or soil, which is established by means of field permeability tests. This book assembles information on rock and soil grouting from various sources, together with the author's personal experience on several grouting projects. Some aspects of permeability testing of rock and soils are elaborated, and the use of theoretical ground water percolation studies for clarification of design options for grout curtains are presented. The results achieved by grouting are presented and analysed on examples of constructed grouting works (curtains, tunnels, foundations, lifting of structures).Particulars of the performance of the permeability tests and their evaluation are studied in some detail, since they can very much distort the results obtained, and thus lead to erroneous design assumptions. Systematic grouting and adjustment of the injection process to the development of grout consumption and pressure during injection is discussed in connection with the achievement of the required permeability standard. The application of grouting to reduce the permeability and the deformability of the foundation of dams and hydrotechnical structures is presented, together with a number of illustrative examples. Characteristics of contact and consolidation grouting of dam foundations and tunnel linings are described. The possibilities and examples of rock prestressing by means of grouting are reported, and the results from several applications are discussed. Examples of lifting and levelling leaning structures by means of grouting are also reviewed. The book is illustrated by 180 drawings and 20 photographs, and a list of symbols used in the formulae, plus a glossary of specific terms used in grouting, are included at the end of the book.The book is intended for organizations, civil engineers and geologists involved in the exploration, design, construction and supervision of large dams, hydroelectric power projects, tunnels and other underground works. Teachers and students of civil engineering courses in geotechnics, building and construction, rock mechanics, soil mechanics, engineering geology, and some aspects of mining engineering will also find the book useful.
