Description

Technical Field

[0001] The utility model belongs to the field of building construction, and in particular relates to an assembled tunnel communication channel bracket and system. Background Art

[0002] A subway connecting passageway, located between the up and down single-track tunnels, serves as a connection, drainage, evacuation, and fire prevention mechanism. The interconnection between the two tunnels effectively reduces the risk of accidents. If a problem occurs in one tunnel, pedestrians can be transferred to the other through the connecting passageway, greatly ensuring their safety. It is therefore known as an "escape passage."

[0003] When the shield machine is constructing the connecting channel without stopping, the temporary support steel frame is set up to effectively avoid the impact of cross-operation on the shield excavation. At the same time, the tunnel inside the shield is supported and reinforced to avoid deformation and damage of the tunnel segments due to changes in surrounding rock pressure after the special segments at the connecting channel entrance are cut. At the same time, a platform for segment cutting and excavation is provided. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and the best embodiment.

[0022] Figure 1-5 A prefabricated tunnel communication channel support is shown, comprising a ring-shaped support 1 and a connecting support 2 arranged in the ring-shaped support; the ring-shaped support comprises a plurality of prefabricated ring-shaped connecting members 11 connected together; the ring-shaped connecting member comprises a ring-shaped connecting member body; the ring-shaped connecting member body connected to the connecting support further comprises a connecting member 12 (typically as Figure 2 At A in the middle, it is enlarged as Figure 4 shown).

[0023] The annular connecting member body ( Figure 3 ) is an I-shaped steel; bolt holes 13 are provided at both ends of the annular connector body; bolts are connected to the bolt holes of adjacent annular connector bodies to form an annular bracket 1. As one embodiment, the annular bracket 1 is a circle with a radius of 1.5m and weighs about 8 kilograms.
