Abstract

The invention belongs to the technical field of tunneling construction equipment, and discloses a cutting part, tunneling equipment and further discloses a tunneling method. The cutting part is arranged in the front of a machine body of the tunneling equipment, and includes a middle part rotary tool holder, cutting arms arranged in the circumferential direction of the middle part rotary tool holder, a first driving part and a second driving part, and cutting power heads are arranged at the ends of the cutting arms; the first driving part drives the action of the middle part rotary tool holder;and the second driving part drives the actions of cutting arms and the cutting power heads. The tunneling equipment comprises the machine body, a cutting part body and a conveying system, a walking part is arranged on the lower part of the machine body, and a power system and a control system are arranged on the machine body, and the cutting part body is arranged at the front end of the machine body. According to the cutting part, the tunneling equipment and the tunneling method, the overall structure is reasonable in design; and by configuring the two cutting power heads and the large middlepart rotary tool holder, a new tunneling construction technology is realized, the cutting efficiency is high, and the requirements of operation under specific geological conditions can be met.

Description

technical field [0001] The invention belongs to the technical field of tunnel excavation construction equipment, and in particular relates to a cutting part, tunnel excavation equipment and an excavation method. Background technique [0002] At present, in the construction of tunnels, especially in the construction of short-distance tunnels, cantilever roadheaders are gradually used for excavation operations. In the case of low geological hardness, the construction technology adopts the reserved core soil excavation method, and cantilever roadheaders are used for construction. , the efficiency of the equipment is low, and a special equipment is needed to adapt to partially adopt the reserved core geotechnical method and greatly improve the efficiency of construction and excavation. Contents of the invention [0003] The object of the present invention is to address the above existing problems and deficiencies, to provide a cutting section, tunnel boring equipment and tunne...
