Level transportation in shaft and side drift construction
Shaft and side drift construction, also known as tunnel driving, is a mode of construction that excavates and constructs a tunnel by digging out a large hole geological structure in the direction of the transportation route. Level transportation is an important part of tunnel construction. Its main features are the construction of support and waterproof structure, the use of shield machine and the automated operation of the operation platform.
Compared with other excavation modes, shaft and side drift construction has the advantages of less affected by the terrain and the ability to construct a straight tunnel sure no tunnels elsewhere. The transportation of level is usually the first step in this form of construction. Proper organization of level transport can make the entire project advance smoothly and ensure that the safety of the adjacent environment is not affected.
The main purpose of tunnel level transportation is to transport the excavated earth, stones and other construction materials from the working surface to the upper or lower working surface, or from the tunnel. It is an important part of tunnel construction transportation, and it has certain requirements for the comprehensive performance of construction support, waterproof structure and transportation machinery.
The most important point in level transport is the construction of the supporting and waterproof system, which requires the use of ground treatment, which can promote the surrounding soil tension, and can also increase the stability of the excavated tunnel. Shield machines and construction platforms are an integral part of level transportation, because they are responsible for the excavation, transportation and loading of the construction materials. A reasonable arrangement of the shield machine can speed up the construction progress and shorten the construction period.
In addition, level transportation in tunnel construction also has some aspects of automated operation. The operation of the platform can be fully automated. Through the combination of advanced computer equipment, a variety of signal detection and output devices and human-machine interface, the system can coordinate the on-site personnel to complete the relevant operations by itself.
Level transportation is an important part of shaft and side drift construction. Through good organization, reasonable design and coordination of personnel and machinery, the entire tunnel construction process can be completed safely and efficiently. At the same time, new technologies such as automated operation of platforms can be used to accelerate the construction process and ensure that the surrounding environment is not affected.
