Tunnel carbon dioxide gas blasting, tunnel one-time blasting technology
With the continuous development of science and technology, the blasting technology in tunnel construction is also constantly improving. Traditional tunnel blasting technology has certain safety risks and is relatively inefficient. In order to solve these problems, the technology of carbon dioxide gas blasting in tunnels came into being. This technology uses carbon dioxide as the blasting medium, which has the advantages of safety, high efficiency and environmental protection, and has become an important technical means in tunnel construction.
The principle of tunnel carbon dioxide gas blasting technology is to use the rapid expansion of the gas produced by the instantaneous evaporation of liquid carbon dioxide, and transfer the energy of the explosive to the rock to break it. This technology is safer than traditional explosive blasting. First of all, carbon dioxide is a non-toxic and harmless gas, which does not produce harmful gases during use, and is harmless to the environment and human health. Secondly, the energy transfer process of carbon dioxide gas blasting is relatively gentle, and does not produce excessive vibration and shock waves, thus reducing the impact on the surrounding environment.
The advantages of CO2 blasting technology in tunnels are not only in terms of safety, but also in terms of construction efficiency. Due to the high pressure of carbon dioxide gas, it can quickly transfer energy, making the rock crushing more uniform, and reducing the difficulty of subsequent treatment. At the same time, this technology also has the advantages of environmental protection and energy saving, which meets the requirements of the current society for sustainable development.
However, there are certain limitations to the CO2 blasting technology in tunnels. First of all, the storage and transportation of liquid carbon dioxide requires special equipment and conditions, which increases the construction cost. Secondly, there is still a certain gap between the construction efficiency of this technology and the traditional explosive blasting, and further technical improvement and optimization are needed.
Nevertheless, with the continuous development of tunnel construction technology, it is believed that the tunnel carbon dioxide gas blasting technology will become more and more mature and popular. In the future, this technology will be applied in more tunnel construction, bringing more advantages and value to project safety, efficiency, and environmental protection.
In addition to the carbon dioxide gas blasting technology in tunnels, one-time blasting technology is also an important technical means in tunnel construction. Through accurate calculation and control, the entire tunnel section is excavated in one go, avoiding the safety hazards and inefficiencies caused by multiple excavations and blasting. One-time blasting technology has the advantages of fast construction speed, high safety performance and low cost, and has been widely used in tunnel construction at home and abroad.
In practice, one-off blasting technology requires detailed analysis and design according to the actual conditions of the tunnel. First of all, it is necessary to have a comprehensive understanding and evaluation of the geological conditions, cross-sectional dimensions, construction equipment, etc. of the tunnel. Then, through accurate calculation and control, a reasonable blasting plan and construction plan are formulated. Finally, during the construction process, it is necessary to strictly control the construction quality to ensure the successful implementation of one-time blasting.
The advantages of one-time blasting technology are not only reflected in the construction efficiency and safety, but also can effectively reduce the construction cost and improve the quality of the project. At the same time, the technology reduces the impact on the surrounding environment and meets the requirements of sustainable development. However, there are also certain limitations of one-time blasting technology, such as high requirements for geological conditions and difficult construction. Therefore, in practical applications, it is necessary to select and apply according to the specific situation.
To sum up, tunnel carbon dioxide gas blasting technology and one-time blasting technology are two important technical means in tunnel construction. These two technologies have their own advantages and scope of application, and need to be selected and applied according to the actual situation. In the future, with the continuous development of science and technology, it is believed that these two technologies will be more mature and perfect, bringing more advantages and value to tunnel construction.
