Book excerpt: Excerpt from Shield and Compressed Air Tunneling Tunneling is a branch of Engineering, therefore, which the student, whether still in college or grown gray in bending the forces of nature to the use and benefit of mankind, cannot and must not neglect. N o matter what his special branch may be, the engineer may be called upon to take his part in the construe tion of a tunnel or in deciding whether he shall or shall not build a tunnel, and if so, by what method he shall build it. He may be the chief on whose shoulders rest the responsibilities of making the final decision and of directing the efforts of a staff of experts, or he may be a youngster fresh from college, serving his first term as a draftsman, inspector or rodman on the design or construction of such a tunnel.

This book was released on 2015-08-06 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Tunnel Shields and the Use of Compressed Air in Subaqueous Works Although the employment of a shield, with or without the aid of compressed air, in tunnelling operations is of English origin, and the length of tunnels so constructed in this country is many times greater than the total amount of similar work elsewhere, the subject is nowhere dealt with in Engineering text books written in English, except in Simms' Practical Tunnelling and Prelini and Hills' Tunnelling, which, however, touch only slightly on it as a part of the general history of tunnelling. Except for a few pages in these works, no account in English of shield-work exists save in the form of papers printed in the Proceeding of the Institution of Civil Engineers and some description of current works which have from time to time appeared in the technical journals. In French two books only on the subject have appeared: the very complete work by M. Legouez, L' Kmploi du Boueiier dans la Construction des Souterrains, and M. Philippe's Le Boudier, which gives some interesting information on recent French tunnel works. The Author hopes, therefore, that a history of recent developments in shield-work may be found of some use to his profenuona) brethren, if only by collecting in one volume a mass of information hitherto scattered through many publications, and consequently difficult and troublesome of access. He has treated as briefly as possible the early records of the shields, and of compressed air working, holding, indeed, that only with Mr. Greathead and his Tower subway shield the history of practical tunnelling by shield really commences, but of the developments witnessed since he has endeavoured to present as clear a record as the limit* of one volume will permit. Of the Great head shield work, the "assisted shield" method of tunnelling, and the various subaqueous tunnels recently built in and around London, he may claim to write from personal knowledge, supplemented by information generously placed at his disposal by the Engineers engaged in the various undertakings described.

Download or read book Mechanised Shield Tunnelling written by Bernhard Maidl and published by John Wiley & Sons. This book was released on 1996-12-16 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its early beginnings in 1806, this type of tunnelling has become one of the most important techniques. While Japan's current pioneering role cannot be denied, the state of development in Europe has reached a high level of international recognition. This book explains the history of this construction method, outlining basic information and presenting the various types of shields and linings with the corresponding equipment and range of applications. It examines various projects, including not only such large ones as the Channel or the Belt tunnel, but also small, equally interesting projects such as underground railways. The problems involved as well the technology used to confront them are fully described, and the text is structured in such a way that readers are led from the basics of this construction method, via the essential functional elements of the shield machines and on to the different types of shields. The universality of the book is guaranteed by the three expert authors, a researcher, machine manufacturer and contractor respectively. Invaluable for current and future tunnelling projects and a must for all those working in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Uses of Compressed Air: With Illustrations The most important application of compressed air in the past has been that to rock drills in tunnels and mines, and in both these fields of activity the drill has accomplished wonders within a decade. America can claim, at Hoosac Tunnel, the first general application of the rock drill, followed by the work at Hell Gate, and in all the tunnels of the Alps, and in our own and other countries. The New York Aqueduct, 30 miles in length, was made with such remarkable speed only by the use of compressed air driving the rock borers. Another instance of rapid tunnelling by the use of compressed air is cited in the work at Niagara Falls, where 50 feet of tunnel was excavated in the short space of six months, and it is to be observed that, in locations permitting the use of shafts at frequent intervals, a tunnel ten miles in length can be constructed as quickly as that of one mile.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The City and South London Railway, Vol. 1: With Some Remarks Upon Subaqueous Tunnelling, by Shield and Compressed Air There are three pairs of pumping engines, so arranged that each can be worked independently of, or jointly with, either of or both the others, and controlled automatically by the accumulator in the usual way. Permanent Way - It was thought to be very desirable to avoid the introduction of ballast on this line with a view to the comfort of travellers, having regard to the strong air currents set up by the trains, and to the durability of rolling stock, especially of the electric locomotives, and of the way itself. The rails, weighing 60 lbs. Per yard, are placed upon cross Sleepers resting directly upon the cast-iron segments of the tunnel, Figs. 14 and 15, Plate 3. The rails, it will be observed, are single-headed and are set some distance from the ends of the Sleepers. This permanent way, though subject to the disadvantage of increasing the resonance in the tunnel, gives remarkably good results as regards repairs and maintenance.
