Rock tunnel driving method

Abstract

The invention discloses a rock tunnel driving method. The rock tunnel driving method comprises the steps that (1) geological exploration is conducted on a to-be-driven tunnel section, and a geologicalexploration report is formed; (2) tunnel construction design is conducted according to a rock tunnel engineering section in the geological exploration report obtained in the step (1), and a tunnel construction design report is formed; (3) according to the tunnel construction design report obtained in the step (2), a rock tunnel driving device is used for tunnel excavation on a to-be-constructed rock mass; (4) anchor rod spraying-protection support construction is conducted on a tunnel excavated through the step (3); and (5) later construction treatment is conducted on the tunnel subjected tospraying-protection support through the step (4). Drilling explosion is not used so as to ensure construction safety, therefore, structural damage to a mountain or a whole stratum (rock mass) in the construction process can be reduced, the stability of the mountain or the stratum is ensured, the construction efficiency can be further improved, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to the field of tunnel excavation, in particular to a rock tunnel excavation device. Background technique [0002] The traditional tunnel excavation construction mostly adopts the blasting method and the shield method. Existing shield tunneling machines are only suitable for tunnel construction with loose pebbles and mudstones. For rocky tunnel construction, the construction progress of shield tunnel boring machines is slow, the cost is extremely high, and the shield machine is bulky. Difficult to transport, not suitable for complex terrain. The existing rock tunnel construction mostly adopts the mining method, and the mining method mostly needs to be excavated by drilling and blasting, so it is also called the drilling and blasting method. Because this method uses explosives to remove slag after blasting, the tunnel walls formed by blasting are uneven, requiring a lot of manual repairs, and the blasting will inevitably cause da...

AI Technical Summary

Problems solved by technology

Because this method uses explosives to remove slag after blasting, the tunnel walls formed by blasting are uneven, requiring a lot of manual repairs, and the blasting will inevitably cause damage to the mountain and rock structures, resulting in poor stability of the mountain. During the process, there will be dead bodies caused by the delayed explosion of the detonator, and in the case of poor mountain structures, landslides are likely to occur, which endangers the safety of construction personnel and equipment, and the cost of manpower and other materials invested in tunnel construction to ensure safety continues to increase.
