Embodiment Construction
[0024] Embodiments of the present invention will be further described below in conjunction with examples.
[0025] Such as Figure 2-Figure 6 As shown, the device of the present invention mainly includes a structural main body 1 , an embedding rod 2 , a cylindrical rod body 3 and a restricting ring 4 .
[0026] The structural main body 1 is formed by symmetrical welding of a hollow steel pipe 15 and four connecting seats 13 with a certain thickness. Make corresponding connections. The structural main body 1 is mainly used to connect the other components and fix the relative positions between the components.
[0027] The upper end of the embedding rod 2 is provided with a semicircular sawtooth 8, and the lower end has a barb claw that can be embedded in the rock mass, and the end of the embedding rod 2 near the sawtooth 8 is provided with an embedding hole 12. During installation, the embedding rod 2 is arranged in the gap 19 of the connecting seat 13, and is connected with ...
