Available in PDF, EPUB and Kindle. Book excerpt: This book puts forward a technological system for the construction of subsea tunnel using drilling and blasting method. Taking the water-induced disaster as the core risk, the safety guarantee system for large cross-sectional subsea tunnels is established. The composite grouting technology referred to ground reinforcement and water plugging is established, which breaks through the technical bottleneck of subsea tunnel construction in highly permeable strata. The process control theory based on water inrush mechanism is created, which gets rid of the over-dependence on engineering experience for disaster control of submarine tunnel. An active control waterproof drainage system based on the synergy of reinforcement ring and support system is invented to solve the contradiction between the control of water displacement and water pressure. The above-mentioned achievements have been successfully applied in the first three large cross-sectional subsea tunnels in China, and have played a key role in the construction safety. The proposed technological system can improve the overall construction level of subsea tunnel, which can provide reference for the design and construction of subsea tunnels, especially for those crossing through weakness zones.

Download or read book Tunnels and Underground Cities Engineering and Innovation Meet Archaeology Architecture and Art written by Daniele Peila and published by CRC Press. This book was released on 2020-06-26 with total page 810 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art. Volume 7: Long and Deep Tunnels contains the contributions presented in the eponymous Technical Session during the World Tunnel Congress 2019 (Naples, Italy, 3-9 May 2019). The use of underground space is continuing to grow, due to global urbanization, public demand for efficient transportation, and energy saving, production and distribution. The growing need for space at ground level, along with its continuous value increase and the challenges of energy saving and achieving sustainable development objectives, demand greater and better use of the underground space to ensure that it supports sustainable, resilient and more liveable cities. The contributions cover a wide range of topics, from studying tunnels in squeezing ground conditions, via case studies on the Brenner Base Tunnel, the second Gotthard Tunnel, CERN (HL-LHCand the Dubai Strategic Sewerage Tunnel, to TBM steering difficulties. The book is a valuable reference text for tunnelling specialists, owners, engineers, archaeologists, architects, artists and others involved in underground planning, design and building around the world, and for academics who are interested in underground constructions and geotechnics.

Download or read book On the Safety Lamp for Preventing Explosions in Mines Houses Lighted by Gas Spirit Warehouses Or Magazines in Ships Etc written by Humphry Davy and published by Cambridge University Press. This book was released on 2012-06-14 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-taught chemist and inventor Sir Humphry Davy (1778-1829) was one of the first professional scientists of his age. President of the Royal Society from 1820 to 1827, he was also a brilliant lecturer whose popularising of science made him famous. He also pioneered electrochemistry, isolating potassium, sodium and calcium. But Davy is best known for creating the safety lamp when he was asked to address the frequent occurrence of explosions in coal mines. He realised that firedamp - flammable gases such as methane - was ignited at high temperature by the open flames of miners' lamps. In 1815, he devised a lamp with a mesh screen that prevented ignition of firedamp; this application of science allowed miners to work in greater safety. First published in 1818 and revised in 1825, this work details the invention that cemented Davy's position as a national hero and earned him the Royal Society's Rumford Medal.

Download or read book Immersed Tunnels written by Richard Lunniss and published by CRC Press. This book was released on 2013-03-04 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immersed tunnels have been around for more than a century but remain a relatively unknown form of tunnel construction. For waterway crossings they are an effective alternative to bored tunnels and bridges, particularly in shallower waters, soft alluvial soils, and earthquake-prone areas. Successful implementation requires a thorough understanding of a wide variety of civil engineering disciplines and construction techniques. Immersed Tunnels brings together in one volume all aspects of immersed tunnels from initial feasibility and planning, through design and construction, to operation and maintenance. Get Valuable Insights into Immersed Tunnel Engineering from Expert Practitioners The book presents design and construction principles to give a full appreciation not only of what is involved in an immersed tunnel scheme but also how potential problems are dealt with and overcome. It examines important factors that have to be considered, particularly environmental implications and mechanical and electrical systems. It also gives practical examples of how specific techniques have been used in various projects and highlights issues that designers and constructors should be aware of. In addition, the book discusses operation and maintenance and reviews contractual matters. These aspects are described from the viewpoint of two experienced practitioners in the field who have a wealth of experience on immersed tunnel projects worldwide. As tunnels are increasingly being adopted as engineering solutions around the world, this unique and extensively illustrated reference explores the wide variety of immersed tunnel techniques available to designers and constructors. It provides essential insight for anyone involved, or seeking to be involved, with immersed tunnel projects.
