Novel tunneling method and device

Abstract

The invention relates to the technical field of tunnel construction, and discloses a novel tunneling method and device. A frame-shaped drilling tool located at the front end of a barrel-shaped tunneling device is used for cutting and tunneling along the periphery of the tunnel face, and meanwhile, a soil body cut into the tunneling device is adjusted to be unearthed, so that tunneling of a tunnel is achieved. According to the novel tunneling device, the tunnel barrel-shaped tunneling device can go deep into the stratum through local soil body cutting, and then unearthed in the open space. The tunneling method and equipment are simpler, the requirement for tunneling power is low, construction energy consumption is low, and the problems caused by direct excavation of the tunnel face can be solved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a new tunnel excavation method and an excavation device. Background technique [0002] The shield tunneling method is currently a commonly used construction method for tunnel construction, with a high degree of mechanization and high safety. However, the conventional shield tunneling method is to fully excavate the entire tunnel face, and the excavated soil must be fully reconstructed and then discharged, which is likely to cause water and soil pollution; moreover, the comprehensive excavation and reconstruction of the soil increases the tunnel Construction energy consumption also makes the tunnel construction cost very high. [0003] At the same time, the structure of the existing shield equipment is complex, not only the equipment cost is high, but also the maintenance is difficult, and various types of maintenance need to be shut down. In addition, the integrity o...

Problems solved by technology

However, the conventional shield tunneling method is to fully excavate the entire tunnel face, and the excavated soil must be fully reconstructed and then discharged, which is likely to cause water and soil pollution; moreover, the comprehensive excavation and reconstruction of the soil increases the tunnel Construction energy consumption also makes the tunnel construction cost very high

[0003] At the same time, the structure of the existing shield equipment is complex, not only the equipment cost is high, but also the maintenance is difficult, and various types of maintenance need to be shut down. In addition, the integrity of the shield equipment is strong, it is difficult to assemble in the hole, and the construction convenience is poor.
