Abstract

The invention provides a mud-water open double-mode tunnel boring machine. The mud-water open double-mode tunnel boring machine comprises a shield. The shield comprises a front bin and a rear bin. A main driver is arranged in the middle of the shield and connected with a cutterhead, a detachable scum board is arranged on the cutterhead, a detachable residue gliding groove is formed in the front portion of the main driver, a detachable conveying device is arranged in the middle of the shield, the conveying device penetrates through the main driver, and a detachable cutterhead center partition plate is arranged on the cutterhead. The mud-water open double-mode tunnel boring machine has the advantages that one tunnel boring machine can achieve an open type boring mode and a mud-water balancemode at the same time, the adaptation of the tunnel boring machine to the stratum is improved through switching use of the two boring modes, and efficient, rapid and safe boring construction and the remote hard rock local water-rich stratum is achieved.

Description

technical field [0001] The invention relates to a tunnel boring machine, in particular to a mud-water open dual-mode tunnel boring machine. Background technique [0002] Open TBM and mud-water balance shield are two common tunnel boring machines. The basic principle of open TBM is that the TBM is connected with the excavation surface without forming pressure support. The slag is scraped up by the cutter head scraper and enters the belt conveyor of the main machine, and then transferred to the supporting belt conveyor and subsequent slag discharge system until it is transported to the ground slag yard. The open TBM has high construction efficiency and long excavation distance, but in strong Difficult and inefficient excavation in water-rich formations are industry-specific problems. The basic principle of the mud-water balance shield is that the host part of the shield machine is isolated from the ground, and a closed compartment is formed in front of the front shield and re...
