Tunneling method and tunneling machine

Abstract

The invention discloses a tunneling method and a tunneling machine. The tunneling method includes simultaneously drilling a plurality of holes in the circumferences of rock faces; simultaneously drilling a plurality of holes beside each drilled hole along the corresponding distribution circumference of the drilled hole; repeating the steps until the circumferences are perforated to form rock and soil cores, and crushing the rock and soil cores; carrying out the same steps until the tunneling depth meets preset requirements. The corresponding holes beside each drilled hole are tangential to the drilled hole or are intersected with the drilled hole. The tunneling machine comprises a framework, a drilling device and a drilling propulsion device. The drilling device is positioned at the front end of the framework and comprises a disc, a plurality of drill rods and hydraulic motors, the drill rods are positioned on the disc and are uniformly distributed along the circumference of the disc, the hydraulic motors are arranged a the tail ends of the drill rods, the various drill rods can simultaneously drill holes along a tunneling direction, and the disc can be axially and rotationally adjusted. The tunneling method and the tunneling machine have the advantages that the tunneling method is high in tunneling speed and low in engineering manufacturing cost as compared with an existing method; the tunneling machine is applicable to the tunneling method, and is low in equipment weight and simple in structure as compared with an existing tunneling machine.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a tunnel boring method and a boring machine. Background technique [0002] The 21st century is the century of underground space. With the rapid development of the national economy, my country's urbanization process is accelerating. For a long time to come, domestic urban subway tunnels, hydraulic tunnels, cross-river tunnels, railway tunnels, highway Projects such as pipelines will require a large number of tunnel construction and road boring machines for construction. [0003] Tunnel boring machine is a comprehensive equipment for continuous operation by mechanically crushing rocks, removing slag and supporting. According to the cutting process of the roadheader on the working face, it is divided into full-section roadheader and partial-section roadheader. According to different principles of rock crushing, it can be divided into rolling type (disc hob) roadheader and milli...
