Problems solved by technology

However, this method of mechanical rotary cutting and rock breaking is often affected by external factors such as rock hardness. Especially under extreme working conditions, the excavation speed is extremely slow, and the cutting tool is in contact with the rock. The probability of tool damage is high. It also increases the construction cost

Abstract

The invention discloses a horizontal tunneling device which comprises a tunneling device host machine, at least one electric pulse drill bit and an electric pulse generator, wherein the tunneling device host machine comprises a front shield tube body; a front separation plate and a back separation plate are arranged in the front shield tube body; the electric pulse drill bits are used for crushingrock through mechanical effects of plasma channels, jet flow or pulse waves generated through pulse power discharging, and are all fixed onto the front separation plate and the back separation plate;and the electric pulse generator is connected with the electric pulse drill bit and is used for providing high-voltage electric pulse for the electric pulse drill bit. The horizontal tunneling devicecan realize the rock crushing without the rotation of the electric pulse drill bit; the drill bit cannot easily be abraded; and the pulse discharging energy of the electric pulse drill bits is used for crushing the rock. Compared with mechanical cutting rock crushing through hobbing cutters, the horizontal tunneling device has the advantages that the influence by external factors such as rock hardness is small, so that the efficient rock crushing under the extreme work conditions can be realized; and the rock crushing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of excavation equipment, in particular to a horizontal excavation device. Background technique [0002] Full-face hard rock tunnel boring machines and shield machines, as the main tunnel construction equipment, are widely used in the construction of infrastructure such as urban underground rail transit, railways and road (including underwater) tunnels. [0003] The full-section hard rock tunnel boring machine and shield machine in the prior art usually include a main drive, and the output end of the main drive is provided with a cutter head, and the full-face hard rock tunnel boring machine and shield machine mainly use the The cutter mechanically cuts or breaks the ground to achieve full-face excavation. However, this method of mechanical rotary cutting and rock breaking is often affected by external factors such as rock hardness. Especially under extreme working conditions, the excavation speed is extreme...
