Problems solved by technology

When the common open support structure is installed on the rock wall in the tunnel, the force of the open support structure is uneven, and its support performance is reduced. When the support capacity of the open support structure drops to the limit, it is easy to cause rock formation in the tunnel Dangerous situations such as body collapse will greatly threaten the safety of life and property.

Abstract

The invention relates to the field of track traffic, and particularly discloses an open-type TBM circular steel framed structure. The open-type TBM circular steel framed structure comprises a plurality of arc-shaped steel frames capable of being assembled into a circular steel frame, the arc-shaped steel frames are connected, connecting units capable of adjusting gaps between the adjacent end parts of the two adjacent arc-shaped steel frames are arranged between the arc-shaped steel frames, and the number of the connecting units is greater than or equal to 1. The open-type TBM circular steel framed structure can be tightly attached to the rock wall of a tunnel after mounting, and stable support can be carried out on the rock wall of the tunnel.

Description

technical field [0001] The invention belongs to the field of rail transit, and in particular relates to an open TBM circular steel frame structure and an installation method thereof. Background technique [0002] With the continuous development of urban construction, the demand for rail transit construction is also increasing dramatically. The infrastructure construction of the rail transit is the top priority of the rail construction. While excavating the tunnel, the safety of the construction is ensured. After the tunnel is excavated, it is necessary to reinforce the rock wall of the tunnel and support structures such as arches installation. The support structure in the tunnel usually adopts a conventional "well"-shaped steel support structure. This kind of support structure is slow to install, prestressing is difficult to operate, and the space occupies a large area. After installation, it is inconvenient for personnel to pass, and construction vehicles cannot pass throu...
