Abstract

The invention discloses a high-voltage pulse discharge-mechanical combined rock-breaking full-section tunneling machine, and solves the problems of slow tunneling speed, fast tool wear and the like byadopting a prior mechanical breaking working mode in tunnel engineering. The tunneling machine comprises a tunneling machine main machine, wherein a cutter head and cutter system is arranged on the tunneling machine main machine, and an electrode is arranged on the cutter head and cutter system. The tunneling machine designs a novel electrode scraper with high-voltage pulse discharge and a scraping capability; the electrode of a high-voltage pulse discharge control system is coupled with other mechanical cutters such as a hob and the like, so that the rock breaking efficiency is improved, andthe wear of the cutter is reduced.

Description

technical field [0001] The invention relates to the field of full-section tunnel boring machines in tunnel construction, in particular to a new cutterhead for full-section tunnel boring machines based on high-voltage pulse discharge-mechanical combined rock breaking that improves rock-breaking efficiency and reduces tool wear. Background technique [0002] At present, full-face tunnel boring machines are widely used in hard rock tunnel projects such as railways, hydropower transportation, mines, and municipalities. However, the tunneling efficiency of this mechanical crushing method is often affected by external factors such as rock hardness. Especially under extreme conditions, not only the tunneling speed is extremely slow, but the probability of tool damage is also greatly increased, which brings huge economic losses to the owner and the construction party. . The high-voltage pulse discharge rock breaking method realizes rock breaking through high-voltage arc discharge b...
