TUNNELLING MACHINE, DEVICE FOR ALIGNMENT OF SEGMENTS OF LINING OF TUNNEL RELATIVE TO EACH OTHER, USED IN TUNNELLING MACHINE, AND METHOD OF CONTROL THEREOF Russian patent published in 2020 - IPC E21D11/40 E21D9/00 

FIELD: construction.

SUBSTANCE: present invention relates to construction machines and particularly relates to a tunnelling machine, a device for levelling the lining segments of the tunnel relative to each other, used in the tunnelling machine, and a method of controlling said tunnel machine. In tunnelling machine there installed is mounting mechanism made with possibility of movement in longitudinal direction of tunnel. Mounting mechanism is intended for installation of segments of lining of tunnel, and inner wall of tunnel is formed of multiple elements of lining segment, in series connected to each other. Mounting mechanism is equipped with a lifting element designed with the possibility of retraction pulling upwards and downwards respectively. Device for alignment of lining segments of tunnel relative to each other and mounting mechanism are located in longitudinal direction of said tunnel. Device for alignment of segments of lining of tunnel relative to each other contains support frame, at that support frame supports at least part of multiple elements of lining segment in order to level tunnel shape; support frame is equipped with fixing pins, and in the lifting member there are fixing holes intended for engagement with the locking pins. Besides, according to the present invention, a method is provided to control said device for alignment of segments of the lining of the tunnel relative to each other. According to the present invention also disclosed is a tunnelling machine comprising the above device for alignment of segments of the lining of the tunnel relative to each other.

EFFECT: this invention ensures qualitative erection of tunnel and efficiency of construction works, and also provides such advantages as simplicity and compactness of structure.
