Driving and supporting of shaft and tunnel
Shaft and tunnel driving and supporting is an important method used in civil engineering construction and mining operations. Compared with traditional civil engineering construction, Shaft and tunnel driving and supporting has its own unique advantages, such as high construction speed, large production capacity, wide range of adaptability and flexibility, etc. In order to ensure the quality of Shaft and tunnel driving and supporting construction, the technical personnel of Shaft and tunnel driving and supporting need to think deeply, be more careful and rational, understand the corresponding knowledge and pay attention to the details in the construction.
The driving and supporting of Shaft and tunnel are two different concepts. For the driving part, Shaft and tunnel refer to the construction process from the ground to the underground. The construction of Shaft and tunnel requires not only professional technology, but also the use of construction machinery. In this part, hole tunneling machine and roadheader are the main force in construction. The hole tunneling machine is generally used for the construction of circular cross-section tunnels, while the roadheader is generally used for the construction of tunnels with large cross-section area.
The supporting part of Shaft and tunnel is mainly about the supporting technology after the driving. This part is also related to a variety of factors, such as environmental engineering and geological conditions. After Shaft and tunnel driving is completed, the supporting project immediately follows, and the construction of supporting structure is the main task. Generally speaking, the most commonly used techniques for supporting the Shaft and tunnels include steel brackets, concrete pipe supports, anchors, ceiling piers, shotcrete walls and so on.
In the driving and supporting of Shaft and tunnel, shake protection and stability are the two basic requirements. What’s more, the inspection and maintenance of Shaft and tunnel in operation is also essential. Shaft and tunnel need to be regularly maintained, overhauled and tested. In the construction process, it is necessary to strengthen the inspection and supervision, carry out daily routine inspections, and solve the problems found in time.
Shaft and tunnel driving and supporting are important links in highway engineering and mining operations and have wide application. Its quality determines the safety of mining operations. Therefore, the construction of Shaft and tunnel needs to be carefully planned, and all staff should hold the attitude of meticulous and serious work.
