THE TUNNEL STURUCTURE FOR NONE OPEN CUT TYPE TUNNEL PRESSING

摘要

The present invention relates to a front tip structure for trenchless tunneling and, more specifically, to a front tip structure for trenchless tunneling, on which a chain excavator is mounted and therefore which can easily enter underground and has excellent workability. The front tip structure for trenchless tunneling, which forms a tunnel structure by a trenchless construction method, includes: a structure body with a certain length formed after the shape of a tunnel; a front injection part including multiple hydraulic motors installed inside the structure body, a chain gear installed at the front of each of the hydraulic motors, and a chain unit installed at the chain gear and rotated by rotation of the hydraulic motors; a length adjustment support part connecting the multiple hydraulic motors to each other and adjusting a distance between the hydraulic motors; and an inner body installed in the inside of the front injection part and the length adjustment support part. The front tip structure for trenchless tunneling according to the present invention can be easily injected to form a tunnel, thereby reducing the construction period and construction costs for construction of the tunnel.
