Abstract

The invention discloses a self-feeding continual tunneling device and method for a rock tunnel, belonging to the construction field of underground excavating rock tunnels or pipelines. According to the invention, the method comprises the following steps of: firstly, drilling an advance borehole in a rock in front of the tunneling device; secondly, screwing in a tapping bit to the formed rock borehole to form inner threads of the rock; and finally, screwing in a helical tube to the threads of the rock, wherein the helical tube pulls the rear tunneling device which is connected with the helical tube by a thrust bearing to move forwards while screwing in to the threads, so that the tunneling device continually tunnels to achieve the continual tunneling of the rock tunnel while being cut by a cutter head in front of the tunneling device of the rock tunnel.

Description

technical field

[0001] The invention relates to a rock tunnel excavation method, which adopts the method of firstly drilling an advanced drilling hole in the rock and soil body, then tapping the rock in the advanced drilling hole to form a spiral pattern, and then using a screw rod or a spiral tube to screw in along the spiral pattern. , so as to drive the cutter head at the rear end of the screw rod or helical tube to cut and ream the hole to form the tunneling device and tunneling method of the rock tunnel, which provides a new type of tunneling device and tunneling device that can continuously move forward in the rock for the underground tunnel construction technology. The method provides technical support for more fully developing and utilizing the underground space, and belongs to the construction field of excavating rock tunnels or pipelines underground. Background technique

[0002] At present, the rock tunnel boring device (TBM-Tunnel Boring Method) used in the const...
