Construction of Tunnel

1 Technology of Tunnel Construction Development

Along with the world in the 20th century science, technology, economic development, transportation, water conservancy, water and electricity, mining, especially in the urban underground space traffic and the use of the tunnel on the number and difficulty of the higher demand. Massive underground construction for the tunnel construction and technological progress. A lot of bolting and shotcreting support engineering practice and rock mechanics of the rapid development that has led to the modern theory of supporting the establishment On this basis a new Olympic France, Norway and France, shallow mining law more effective construction method; use modern equipment and shield tunneling machine to adapt to the soft, hard rock aquifer formation of driving conditions its reliability, durability, maneuverability and driving at a high speed, it works in the tunnel was growing wider application; impact on the bit and improve hydraulic drilling platform vehicle to the emergence of large-capacity equipment slag, slag equipment shipped to the development, New equipment of the blasting and blasting techniques are perfected, to improve conditions and rock support technology advances, greatly improving the working environment and improve the speed of excavation, drilling blasting driving technology update; submerged underwater tunnel construction technology for the development of cross rivers, the Gulf provides a new and effective means. Built in 1984 in Japan across the Tsugaru Strait Green letter tunnel (length 53.85KM) and completed in 1991 English Channel tunnel (length 50.50KM), from the scale, complexity, or the application of new technology, represent the world in the 20th century tunnel construction level.

Tunnel construction project in China has a long history, but in 1949, before the tunnel smaller scale, the construction technique is relatively backward. After the founding of the People's Republic of China, with the cause of development, the

construction of a large tunnel project, Construction technology has been greatly improved. China Mine Tunnel Construction Project has been more widespread use of the new Austrian law; rock tunnel construction in addition to drilling and blasting tunneling method, but also has started to use the TBM construction; Cities such as digging shallow tunnels dug or covered Construction began using a diaphragm wall, Excavation at the shallow and shield tunneling method has higher technical level. China has a number of railway tunnel over 4000KM, ranking first in the world. My method is to submerged underwater tunnel construction blocks one of the larger countries. With the development of highway construction, especially the high-grade highway in China rise My highway tunnel in quantity and a large-scale development, building technology, especially in overcoming the complexity of the capacity of environmental conditions, have greatly improved. 1995 started the construction of the Qinling tunnel (length 19.45KM) tunnel built in China to make new technology breakthrough. 20 half century after the construction of the tunnel technology and modern management methods, China to build for future growth Tunnel and overcome all sorts of difficulties for the tunnel project laid the foundation. China is a vast, complex geological conditions in mountainous developing countries, urbanization traffic at the initial stages. large-scale water conservancy and traffic cause is rising, the tunnel will cause greater development.

Tunnel construction of the tunnel grew up on progress of development projects and the development and utilization of underground space laid the foundation for the same time, The massive underground project will develop technology for the construction of the tunnel raised new and higher demands. In order to adapt to future large-scale tunnel project for the needs of the Prospect Tunnel Construction direction Tunnel Construction should seriously undertake the following tasks :

Strengthen the construction tunnel to work for exploration

Crossing the design stage of geological survey work on the development program is of great significance, but in normal circumstances, only the site of the

tunnel geological conditions general description of the limited, it can not guide the construction, Construction must be open to further formation of geological exploration. Therefore, the construction of geological prediction technology development and improve the exploration and development of a variety of means, to the rapid and timely access to the maximum number of geological information for a smooth start construction very important.

Mechanization accelerated tunnel construction

Construction for the construction of mechanization is to accelerate the progress of the important means is narrow and foreign tunnel construction technology gap between the important aspect. The most widely used method of drilling and blasting operations, the establishment of a drilling platform vehicle for a few pilot mechanized line (excavation, Slag from the production line; shotcrete operations; FORMWORKING concrete lining of operating lines) to enable drilling and blasting method stronger adaptability, investment returns obvious; in the use of extra-long tunnel boring machine at the core of the comprehensive mechanization technology (excavation, from slag, Lining) long tunnel construction for the high-speed, high-efficiency and high-quality breakthrough. Shen shield development and construction of the mechanization and Automation will allow Urban Underground Construction traffic and more JIANG Xin-Road to be developed faster.

Enhancing the use of new construction techniques

Construction of the tunnel using new technology to improve construction quality and progress of the acceleration has a very prominent role. At present, we should focus on the following areas of applications :

Drilling operations use more powerful drilling machine bored or car, bit more impact on the quality alloy materials and shapes to improve the bit rate accelerated drilling, development of more effective blasting large equipment; Blasting design optimization studies, programming after the computer-controlled drilling; increased drilling and blasting;

Strengthen the wet spray shotcrete and the SFRC applied research, improve construction technology, improving construction conditions, Supporting improve the quality, speed and effectiveness;

Prefab strengthen the lining of the application, the precast concrete lining to the high grade, size small error, Seal assembly for the right direction;

Further improve the auxiliary workers, particularly in strengthening grouting technology (grouting equipment, materials, processes, test), to improve against adverse geological an emergency.

Strengthen the management of the modernization construction of the tunnel

Tunnel Construction adopt modern management methods can be maximized mechanical efficiency, ensure project quality and construction safety. This is our country and abroad narrow the technology gap between the tunnel important aspect.
