Integrated supporting system and tunnel boring machine with same

Abstract

The invention discloses an integrated supporting system for a tunnel boring machine (TBM). The integrated supporting system comprises a duct piece / inverted arch block splicing system, an advanced drilling / reinforcing system, an anchor rod drilling machine system, a rotating system and a horizontal moving and supporting system. The duct piece / inverted arch block splicing system, the advanced drilling / reinforcing system and the anchor rod drilling machine system share the rotating system and the horizontal moving and supporting system. The invention further discloses the TBM with the integrated supporting system. The integrated supporting system for the TBM integrates the duct piece / inverted arch block splicing function, the advanced drilling / reinforcing function, the anchor rod reinforcing function and the like. Two tunnel supporting modes comprising anchor supporting and duct piece lining can be achieved, the duct piece / inverted arch block splicing system, the advanced drilling / reinforcing system and the anchor rod drilling machine system share the rotating system and the horizontal moving system due to structural optimization and reasonable arrangement, and a rotating bearing and a hydraulic electrical control system are omitted, so that the length of the TBM is reduced, the equipment manufacturing and maintaining cost is reduced, and the integrated supporting system can better adapt to tunnel construction, particularly engineering practice with the small city subway tunnel construction heading machine starting and disassembling space, and can better applicable to tunnel liming and supporting on different geological conditions.

Description

technical field [0001] The invention relates to an integrated support system, in particular to an integrated support system for a tunnel boring machine (TBM) and a tunnel boring machine (TBM) with the system. Background technique [0002] The full-face tunnel boring machine (TBM) integrates mechanical, electrical, hydraulic, control, and measurement technologies, and can realize continuous operations of tunnel excavation, ballasting, and support. Compared with the traditional drilling and blasting tunnel construction mode, tunnel boring machine (TBM) construction is safer, more reliable, more efficient, and more environmentally friendly. It has been widely used in water conservancy and hydropower, mining, rail transit, municipal, national defense and other projects. [0003] When using a roadheader for construction, geological factors should be fully considered to ensure that the roadheader has the ability to excavate quickly and pass through safely under weak geological con...

Problems solved by technology

[0005] The traditional tunnel boring machine (TBM) support system, advanced drilling / reinforcement system and bolter system use a special rotary system, which is arranged separately from the segment / invert block assembly system, which has a complex structure and takes up a lot of space. Manufacturing and maintenance The cost is high, and it cannot adapt to the engineering practice of tunnel construction, especially the construction of urban subway tunnels, where the boring machine starts, the demolition space is small, and the support lining requirements under different geological conditions
