Shield tunneling machine capable of simultaneously carrying out tunneling and assembling and construction method

Abstract

The invention discloses a shield tunneling machine capable of simultaneously carrying out tunneling and assembling and a construction method. The shield tunneling machine includes a shield tunneling machine body, an inner tube which can move in the axial direction of the shield tunneling machine body is arranged in a tail shield of the shield tunneling machine body, and the inner tube is providedwith an action performing device which enables the shield tunneling machine body to carry out tunneling and assembling simultaneously. According to the shield tunneling machine capable of simultaneously carrying out tunneling and assembling and the construction method, the synergistic effect of a plurality of tunneling jacks and assembling jacks is utilized by the shield tunneling machine to enable tunneling and segment assembling to be carried out simultaneously, the rapid tunneling of a shield tunnel can be realized, and the construction period of the shield tunnel is shortened; the inner tube in the tail shield of the shield tunneling machine separates the tunneling operation area and the segment assembling operation area independently, so that the safety of the operation areas is greatly improved; and when the construction method that tunneling and assembling are carried out simultaneously is not adopted and the tunneling jacks are not used, the assembling jacks can be exclusivelyused, and the traditional shield tunneling method can be recovered, namely the shield tunneling and the segment assembling can be operated alternately.
