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.

Embodiment Construction

[0041] Such as Figure 1 to Figure 7 As shown, a new tunnel excavation method of the present invention uses the frame-shaped drilling tool 4 located at the front end of the cylindrical excavation device to cut and excavate along the outer periphery of the tunnel face 9, and at the same time adjust the excavation of the soil cut into the excavation device. To realize tunnel excavation. The soil cut into the tunneling device is on the rear end side of the tunneling direction, and the axial stress is applied forward by the stress applying device to form a soil plug that promotes the stability of the face 9; while tunneling, the rear end of the soil plug is exposed. unearthed. Specifically include the following steps:

[0042] Step 1. Site preparation;

[0043] In this step, in addition to hardening the site and ensuring that the relevant hard conditions of the site meet the construction requirements, a reasonable equipment installation plan should be formulated according to th...

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...
