Embodiment Construction

[0029] 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.

[0030] Since large components can only enter the tunnel from the end or side of the TBM, the replacement of large components between the cutter head and the TBM shield cannot be completed. Due to the limited space in the tunnel, the maintenance or replacement of large parts of TBM in the tunnel often adopts the method of excavating shafts or digging circuitous pilot tunnels and expanding the tunnels, resulting in technical problems such as difficult transport...

Abstract

The invention relates to the technical field of TBM equipment, in particular to a method for conveying large parts of a TBM in a tunnel. The method includes the following steps that in the tunneling process of the TBM, surrounding rock is supported and constructed; the TBM retreats to a preset position, and a working area is formed between the TBM and a tunnel face; supporting construction is carried out on the surrounding rock in the working area; side hole excavation and hanging point construction are performed on the side wall of the working area; the TBM is jacked to the tunnel face again;the large parts are transported from the tail end of the TBM and placed in the side holes; the TBM is moved to positions, corresponding to the maintenance position of the large parts, of the side holes. The method for conveying the large parts of the TBM in the tunnel, the side holes used for containing the large parts are excavated in the inner side wall of the tunnel, so that the technical problems that the large parts are difficult to transport, high in replacement cost and low in efficiency are solved.

Description

technical field [0001] The invention relates to the technical field of TBM equipment, in particular to a method for transporting large parts of a TBM 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 take...
