Crossing the Ba Mountain, this tunnel is fearless "Shu Dao Difficulty"!

In recent years, with the continuous extension of the road network to the western mountains and offshore deep -water areas, the length and depth of the road tunnel in my country have continued to increase. Essence For the growth of the growing tunnel project, it is mainly reflected in the complexity of the construction ventilation and drainage, the difficulty of supply guarantee of machinery and materials, complex geological conditions, and decreased construction efficiency. The growth of the highway tunnel is often a key project that restricts the progress of the entire project. The construction progress and quality of construction determine the progress of the entire project. Therefore, it is important how to complete the tunnel construction quickly and quickly. The book "Technical Innovation and Practice of the Construction and Practice of the Construction Technology Innovation and Practice" published by the People's Transportation Publishing House Co., Ltd., relying on the Makuangshan Specialties Tunnel Project of the Basan -Shaanxi Expressway, combined with the results of scientific research innovation and technological research, the system sorted out and summarized. Key technical issues built by the Tunnel of Special Highway. The Makangshan Special Highway Tunnel is located at the junction of Sichuan and Shaanxi. It is a controlled project from G85 Yinchuan to Kunming Highway. The total length of the tunnel is 13.8 kilometers. It mainly crosses sandy rocks, Baiyun rock and quartz glittering long rocks. There are bad geology such as gas and rocky solid. For long -distance monopoly excavation during the tunnel construction, the construction disposal of rock explosion section, long -distance monopoly excavation construction ventilation and hydrogen sulfide disposal, deep large ventilation vertical well construction, underground aircraft room and connection channel construction, tunnel construction to the water environment of the water environment For key technical issues such as influence, the author of this book has carried out a number of theoretical research and technical research, adhering to the principles of security, efficient, innovative and practical, and established the rapid construction organization and mechanical supporting system of Makangshan Special Highway Tunnel, forming a strong rock explosion Duan Weizun monitoring and disposal technology system proposed the construction technology of deep large ventilation vertical wells, and realized the safe and fast construction of the Makangshan Special Highway Tunnel. The main contents of this book include fast construction organization and mechanical facilities, strong rock explosive micro -seismic monitoring and disposal technology, medium -weak rock explosion section flexible protection network rapid construction technology, long -range monopoly excavation construction ventilation and hydrogen sulfide treatment technology, deep large, large large, large and large The construction technology of ventilation vertical well construction, underground aircraft room and connection lane, the impact and evaluation of tunnel construction on the water environment, and the application and innovation of other "four new technologies".
