Problems solved by technology
[0004] The purpose of the present invention is to provide a method for removing a TBM cutterhead in a tunnel. The technical solution provided by the present invention removes the cutterhead in the tunnel, and the tunnel between the cutterhead and the TBM shield can be used as a large part for maintenance or replacement. The working space solves the technical problems of high replacement cost and low efficiency of traditional maintenance or replacement methods, and at the same time, it is also difficult to repair or replace due to the limitation of the buried depth of the TBM

Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0028] The maintenance or replacement of large parts of the existing TBM requires the excavation of shafts, circuitous pilot tunnels or enlarged tunnels. The maintenance or replacement costs are high and the efficiency is low. At the same time, it is also technically difficult to repair or replace due to the limitation of the buried depth of the TBM.
[0029] In order to solve the above technical problems, the present invention provides a method for dismantli...

The invention relates to the technical field of TBM equipment, in particular to a method for removing a TBM cutter head in a tunnel. The method comprises the following steps that in the TBM tunnelingprocess, supporting construction is conducted on surrounding rock; a TBM is receded to the preposition, and a working area is formed between the TBM and a tunnel face; supporting construction is conducted on surrounding rock in the working area, and construction of an anchor cable for locking the TBM cutter head is conducted on the tunnel face; the TBM is jacked to the tunnel face again, and the cutter head is fixed to an anchor cable; the cutter head is removed, so that the cutter head and a TBM shield body are separated; and the TBM shield body is receded to the preposition, and an operationspace is formed between the cutter head and the TBM shield body. According to the technical scheme of the method for removing the TBM cutter head in the tunnel, the cutter head is removed in the tunnel, thus the tunnel between the cutter head and the TBM shield body can serve as the operation space for repairing or replacing large parts, and the technical problems that a traditional repairing orreplacing method is high in replacing cost and low is efficiency, and meanwhile, repairing or replacing is difficult due to limitation of the TBM buried depth condition are solved.
Description
technical field [0001] The invention relates to the technical field of TBM equipment, in particular to a method for removing a TBM cutterhead in a tunnel. Background technique [0002] With the development of my country's economy and society, there are more and more major underground construction projects such as long railways, highway tunnels, water diversion tunnels, and urban subways. The construction technology of tunnels with special lengths, large sections, and complex geological conditions is becoming more and more difficult. The requirements for excavation speed, safety, environmental protection, quality and efficiency are getting higher and higher. Therefore, TBM is more and more used in long tunnels. Shield tunneling is a kind of machine used for underground excavation of tunnels in soft soil. Hard rock tunnel boring machine, also known as rock tunnel boring machine, is generally called TBM in China, that is, full-face rock tunnel boring machine, which takes rock s...
