Abstract

The invention discloses a multi-cutter-disk heading machine which comprises an outer shell. A drive system is arranged at the front end of the outer shell and is connected with an excavation mechanism; the excavation mechanism is provided with a deslagging system and a muck conveying system; the excavation mechanism comprises a plurality of cutter disks; the multiple cutter disks are arranged at the front end of the outer shell in parallel; the orthographic projections of the cutter disks form a shape consistent to the cross section of the outer shell; a gap between each two adjacent cutter disks and a gap between each cutter disk and the outer shell are excavation blind areas; a blind area conical plate is arranged at the position, opposite to each excavation blind area, on the outer shell; the deslagging system comprises a blind area screw conveyer; a rock breaking structure opposite to each excavation blind area is arranged at the front end of the blind area screw conveyer; and theblind area screw conveyer is connected with the muck conveying system. The multi-cutter-disk heading machine provided by the invention not only can achieve the maximum effects of excavation and stirring, but also plays a role in supporting a palm surface to prevent collapse. Meanwhile, the geological application scope of the extra-large rectangular section heading equipment over 14 meters is expanded.

Description

technical field

[0001] The invention belongs to the technical field of tunnel excavation in sand and pebble layers, in particular to a multi-cutter heading machine. Background technique

[0002] With the continuous acceleration of the urbanization process, in the urban underground space construction projects, underground underground excavation mechanical construction has become a trend. Among them, the rectangular tunnel boring machine is used more and more because of its advantages of high space utilization, suitable for shallow covering soil, relatively low construction cost and less impact on the surrounding environment. At present, rectangular tunnel boring machines are mainly used for the construction of subway entrances and exits, street passages, double-lane underpass highways, sidewalks, and comprehensive pipe corridors, but the equipment used is all rectangular sections below 10 meters.

[0003] At present, the tunnel section is developing towards a larger and wide...
