Description

Technical Field

[0001] The utility model relates to the technical field of tunnel excavation, and more specifically to a hydraulic tunnel excavation device. Background Art

[0002] A hydraulic tunnel is a water passage dug in a mountain or underground. It can be used for irrigation, power generation, water supply, water discharge, water transfer, construction diversion and navigation. A tunnel with a free water surface is called an unpressured tunnel; a tunnel with a pressure that fills the entire cross-section and makes the tunnel wall bear a certain water pressure is called a pressurized tunnel. Coal and gas outbursts are prone to occur during the construction of water-bridge tunnels, which is rare in the construction of tunnels or tunnels of water conservancy, highways and railways under construction. Gas construction is risky but cannot stagnate or take up too much construction time. According to design requirements, gas control requires slurry stop walls, hole layout, drilling, gas extraction, effect inspection, grouting and sealing, advanced support, upper and lower steps and left and right staggered excavation of the lower step, system support, etc., among which excavation equipment is required for drilling.

[0003] After searching, the invention patent with announcement number CN105239920A discloses a peristaltic cable tunnel excavation device, which includes a chuck and a stepper motor for driving the chuck; the side wall of the chuck is evenly distributed with at least three claws in the circumferential direction; an arc-shaped top plate is installed at the end of each claw; an A base fixed on the top surface of the chuck, an A drive motor installed on the A base, an A reciprocating screw driven by the A drive motor, and a spiral excavation drill bit fixed on the top of the A reciprocating screw; the nut of the reciprocating screw A is fixedly connected to the A base; a B base fixed on the bottom surface of the chuck, a B drive motor installed on the B base, a B reciprocating screw driven by the B drive motor, and a spiral road-clearing drill bit fixed on the top of the B reciprocating screw; the spiral road-clearing drill bit and the spiral excavation drill bit are symmetrically arranged; the rotation directions of the A reciprocating screw and the B reciprocating screw are opposite; the drilling resistance is small and the drilling penetration is strong by adopting this scheme. However, the above patents have the following disadvantages: the hole has the risk of collapse after drilling, and the driving force provided by only two counter-rotating drill bits is not effective, which makes it inconvenient for the excavation device to move in the hole. Therefore, we propose a hydraulic tunnel excavation device. Utility Model Content
