Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunneling, in particular to a disc type rock tunneling machine. BACKGROUND

[0002] Under the background of the development of urban underground space to deep and complex geology, the efficiency bottleneck of traditional cantilever tunneling technology is increasingly prominent.

[0003] In the face of hard rock geological conditions, cantilever tunneling machines are difficult to meet the needs of modern engineering for high efficiency and safe construction due to low cutting efficiency and severe equipment wear, and there is an urgent need to innovate tunneling technology to adapt to complex hard rock environments. With the scale-up of national water conservancy and hydropower, subway tunnel and underground space development projects, tunneling machine research and manufacturing technology continues to iterate, and engineering practice puts forward higher requirements for the cross-section adaptability of tunneling equipment. However, the existing cantilever tunneling machine still has significant defects: Whether it is a cannon head equipped with pick teeth or a conical cutter head, the single cutting or rolling rock breaking mode is inefficient and the tool wear is astonishing, making it difficult to perform hard rock tunneling tasks. In addition, the existing tunneling machine cannot realize simultaneous tunneling and anchoring in hard rock working scenarios, and the supporting process lags behind the excavation progress, not only prolonging the construction period, but also possibly causing safety hazards, which seriously restricts the overall construction efficiency. These technical problems need to be solved to promote the leap-forward development of underground space tunneling technology.

[0004] Current hard rock roadway construction mainly relies on full-face hard rock tunnel boring machines (TBM), drill-and-blast methods, and cantilever tunneling machines. Although TBM has gradually gained popularity due to its domestic promotion and application, it is still difficult to take advantage of its size, mobility, construction preparation, auxiliary systems, long manufacturing cycle, and complex shape of the roadway and curved and undulating roadways. The drill-and-blast method is tedious, with large damage to surrounding rock from blasting vibrations, and subsequent support work is time-consuming and inefficient. Although the cantilever tunneling machine has some mobility, its rock breaking efficiency is low, and the tunneling and anchoring processes are separate, resulting in a long cycle and inability to achieve efficient continuous production. In view of the shortcomings and deficiencies of cantilever pick-type tooth rock breaking technology, full-face TBM roller rock breaking technology, and drill-and-blast rock breaking technology in dealing with hard rock tunneling, the development of new hard rock breaking technology for irregular cross-sections will greatly improve efficiency, safety, environmental protection, and economy. From the existing technical achievements, it is necessary to realize the industry's difficult problem of breaking hard rock in irregular cross-sections quickly and to realize continuous operation without blasting, such as It is necessary to efficiently and reliably improve the efficiency of roadway rock breaking.
