Anti-jamming single-shield TBM main machine structure and anti-jamming method thereof

Abstract

The invention discloses an anti-jamming single-shield TBM main machine structure and an anti-jamming method thereof. The anti-jamming single-shield TBM main machine structure and the anti-jamming method thereof are used for solving the technical problem that in the prior art, jamming is easily caused on single-shield TBM faults, crushed zones and other poor stratums. The anti-jamming single-shield TBM main machine structure comprises a cutterhead. The cutterhead is connected with a shield body. The shield body comprises a front shield, a middle shield and a tail shield which are sequentially connected. Multiple detachable front shield check pulp brushes are arranged at the front end of the front shield, multiple upper tail brushes and multiple lower tail brushes are arranged on the shield wall of the rear end of the tail shield, the upper tail brushes correspond to the front shield check pulp brushes, multiple trigger mud connectors are arranged on the shield walls in the front shield and the tail shield, the trigger mud connectors are connected with a mud storage tank through a mud pipe, and a mud conveying pump is arranged on the mud pipe. The positions between dug cavity walls and the shield body are filled with trigger mud, a stress field generated after the cavity walls are dug is converted into a tertiary stress state from a secondary stress field, the stratum deformation rate is reduced accordingly, a single-shield TBM can smoothly and stably pass through a crushed stratum, and construction quality and construction safety are guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction of a full-face rock tunnel boring machine, in particular to an anti-jamming machine single-shield TBM host structure and an anti-jamming machine method. Background technique [0002] The full-section rock tunnel boring machine is called TBM for short. Its construction has the characteristics of safety, high efficiency, high degree of automation, and one-time forming of the entire tunnel section. It is currently one of the most advanced equipment for large-scale mechanized supporting tunnel construction. It has been widely used in railways, municipal In the construction of water conservancy and other projects, it is extremely important for the performance improvement and optimization of TBM equipment, and it is also the trend of excellent industrial development. [0003] Single-shield TBM is one of the models of hard rock tunnel boring machines. The host machine mainly includes cutter head, ma...
