Top tunneling machine for long-distance tunneling and construction method thereof

Abstract

The invention discloses a top tunneling machine for long-distance tunneling and a construction method thereof. The top tunneling machine comprises a machine head, a rack, and a plurality of spiral casing devices, wherein the machine head is used for heading and drilling, and the machine head is provided with a knife disc and a main drive for driving the knife disc; the rack is provided with a maintop device for pushing the machine head; and the spiral casing devices are used for supporting and discharging slag, the main top device is connected with the fixing part of the machine head by the spiral casing devices connected successively, the spiral casing devices are connected with the machine head and main top device in a disassembly mode, and the spiral casing devices are provided with main drives independent of the knife disc and a spiral driving device to realize deslagging. According to the top tunneling machine for long-distance tunneling and the construction method thereof, the tunneling structure is arranged as the detachable sectional structure of the machine head and spiral casing devices, the spiral casing devices for discharging the slag are independent of the drive of the cutter disc, thus the tunneling distance is not limited by a power plant, and the applicable range of the tunneling length of the tunneling machine. The construction method can realize continuous extension of the top tunneling machine into the interior of the excavation part, and is suitable for long-distance tunnel construction.

Description

Technical field [0001] The invention relates to the technical field of tunnel construction, and more specifically, to a jacking machine for long-distance tunneling and a construction method thereof. Background technique [0002] Tunnel construction often encounters projects that require very high construction efficiency and long driving distances, such as coal mines or tunnel collapse rescue. [0003] At present, similar construction equipment on the market mainly includes mud-water / earth pressure balance pipe jacking machine and spiral pipe jacking machine, but these equipments have many limitations at present. The mud-water / earth pressure balance pipe jacking machine requires a lot of auxiliary equipment, the construction takes up a lot of space, and the construction efficiency is slow. Although the spiral pipe jacking machine has greatly improved the construction efficiency compared with the mud water / earth pressure balance pipe jacking machine, the main driving device of the e...

AI Technical Summary

Problems solved by technology

Although the screw pipe jacking machine has greatly improved the construction efficiency compared with the muddy water / earth pressure balance pipe jacking machine, the current existing screw pipe jacking technology, the main drive device is located on the originating side, and a single main drive in the center is used. This driving form determines that the equipment cannot realize long-distance excavation

[0004] With the continuous emergence of difficult pipeline projects, when encountering projects that require high driving efficiency, long-distance driving, high precision steering and deviation correction, rock / large-grained rock formations, and no receiving wells, the existing The top excavator technology has been powerless
