[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0024] Reference Figure 1 - Figure 4A subway tunnel support structure includes an arc-shaped support plate 1 and an arc-shaped support plate 2: an installation unit 3 is provided on the lower inner wall of the arc-shaped support plate 1 and the arc-shaped support plate 2, a slot 4 is provided on the right side of the arc-shaped support plate 1, and an insert block 5 is fixedly connected to the left side of the arc-shaped support plate 2, which is adapted to the slot 4. The arc-shaped support plate 1 and the arc-shaped support plate 2 are connected together through the provided slot 4 and the insert block 5, and are limited by the connecting screw 1 302. A nut is provided on the outside of the connecting screw 1 302 to facilitate limiting the connecting screw 1 302.

[0025] The mounting unit 3 includes a bottom plate 301, which is arranged on the lower inner wall of the arc-shaped support plate 1 and the arc-shaped support plate 2, and two side plates 303 are fixedly connected to the left and right sides of the bottom plate 301. A plurality of support rods 304 are fixedly connected between the two side plates 303, and a plurality of connecting screws 306 are arranged on the outer side of the side plates 303. A connecting screw 2 305 is arranged on the outer side of the bottom plate 301, and the connecting screw 2 305 is threadedly connected to the arc-shaped support plate 1 and the arc-shaped support plate 2, and the upper ends of the connecting screw 2 305 pass through the upper sides of the arc-shaped support plate 1 and the arc-shaped support plate 2, and the upper ends of the connecting screw 306 pass through the upper sides of the arc-shaped support plate 1 and the arc-shaped support plate 2, The connecting screws 306 are all threadedly connected to the arc support plate 1 and the arc support plate 2.
