Abstract

The invention discloses a dual-mode tunneling machine, which comprises a front shield, a telescopic outer shield, a telescopic inner shield, a supporting shield and a shield tail arranged sequentially from front to back, and the telescopic outer shield is slidably sleeved on the outer side of the telescopic inner shield; The earth pressure seal assembly is used to switch the working mode of the dual-mode roadheader to the double shield TBM mode or the earth pressure mode through the installation and removal of the earth pressure seal assembly; the earth pressure seal assembly includes a telescopic gap seal and a shield inner seal; In earth pressure mode, the telescopic gap seal is sealed and connected in the telescopic gap between the telescopic inner shield and the telescopic outer shield, and the shield inner seal is sealed and connected between the telescopic inner shield and the support shield; in the double-shield TBM mode, the soil Compression seal assembly removed from dual mode roadheader. Through the removable installation of the telescopic gap seal and the inner seal of the shield, two working modes can be realized. In the long-distance construction of complex strata, it is only necessary to switch the mode of the roadheader without replacing the equipment, which can improve the construction efficiency.

Description

Technical field [0001] The present invention relates to the field of shield construction technology, in particular to a dual-mode TBM. Background [0002] In the construction of complex formations over long distances, it may be necessary for TBM equipment with different working modes to carry out boring operations, such as earth pressure mode and TBM mode, resulting in the need to switch equipment when construction in different locations, reducing construction efficiency. [0003] Therefore, how to improve the efficiency of construction, is a technical problem that those skilled in the art currently need to solve. Contents of the Invention [0004] In view of this, the object of the present invention is to provide a dual-mode TBM, capable of achieving earth pressure, double shield TBM dual-mode tunneling, can ensure construction efficiency. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] A dual-mode TBM, comprisin...
