Abstract

The invention provides a hard rock tunneling device and a hard rock tunneling method. The hard rock tunneling device comprises a cutter head, a driving device, a cutter, and an auxiliary mechanism; the driving device is arranged on a first surface of the cutter head and is used for driving the cutter head to rotate; the cutter is arranged on the second surface, opposite to the first surface, of the cutter head and is used for cutting rocks; and the auxiliary mechanism is arranged on the cutter head and used for assisting the cutter in cutting the rocks. According to the hard rock tunneling device and the hard rock tunneling method, the auxiliary mechanism assists the cutter in cutting the rocks, so that the rocks can be effectively cut, the rock breaking capacity of the hard rock tunnelingdevice is improved, the loss of the cutter is avoided, the service life of the cutter is prolonged, the replacement frequency of the cutter is reduced, the rock breaking efficiency and the construction efficiency are greatly improved, especially for high-strength rocks, and the rocks can be cut more efficiently.

Description

technical field [0001] The invention relates to the technical field of hard rock excavation, in particular to a hard rock excavation device and a hard rock excavation method. Background technique [0002] In the field of hard rock excavation, the commonly used rock breaking device is the shield machine (TBM). Due to the high excavation efficiency of the shield machine, and the safety is much higher than that of the drill and blast method, more and more mountain tunnels are constructed using the shield machine. However, when encountering high-strength rocks, such as granite, marble, etc., the rock-breaking ability of the shield machine decreases, the excavation efficiency drops significantly, the tool wears out quickly, and the tool needs to be replaced frequently, which reduces the utilization rate. According to estimates, the cost of tool loss accounts for about 30% of the construction cost, and the downtime of the shield machine caused by tool inspection and replacement a...
