Abstract

The invention discloses a square shield machine, which includes a shield body and an excavation part. The excavation part includes a cutter head, a cutter bar and a square formwork; the cutter bar is movably connected with the square formwork; Lello triangle; the axis of the cutter bar coincides with the axis of the cutter head and is used on the cutter bar through a square template. The axis of the cutter bar coincides with the axis of the cutter head. Therefore, the movement axis trajectory of the cutter bar can be limited and standardized. Realize the control of the cutter head movement axis, the movement of the cutter bar and the motion on the cutter head are coupled to form a Lelot triangle. When the Lelot triangle rotates, the center must be moving, otherwise, the cutter head can only tunnel to get a circular section In the tunnel, the motion envelope of the cutter head is finally square, and the shield machine construction is used to form a square section of the tunnel, which avoids secondary construction to level the bottom of the current circular section.

Description

【Technical field】 [0001] The invention belongs to the technical field of shield tunneling, in particular to a square shield tunneling machine. 【Background technique】 [0002] The principle of the current shield machine excavating the tunnel is to use the rotary motion of the cutter head around the axis to cut the geological content, equip the transportation device inside the shield machine, transport the muck out, and then realize the tunnel pipe at the back of the shield machine. The splicing of the walls finally forms the entire cylindrical tunnel structure. [0003] The shield machine is the mainstream engineering equipment of the existing tunnel engineering, and the utilization rate is extremely high. However, the current shield machine uses a cutterhead with a fixed axis, and not all the cylindrical spaces formed by the shield machine with a fixed axis cutterhead are perfect. To put it into practical use, it is necessary to re-construct and repair the tunnel completed ...
