Abstract

The invention relates to the technical field of tunnel construction, in particular to a tunnel supporting device and method, a first telescopic rod is rotatably arranged on a foundation platform, a supporting assembly is arranged at the other end of the first telescopic rod, and meanwhile the supporting assembly and a to-be-supported tunnel wall are arranged in a spaced mode; in addition, the shotcreting and anchoring assembly is arranged on the supporting assembly. By controlling the telescopic length of the first telescopic rod, the supporting assembly and the to-be-supported tunnel wall can be arranged in a spaced mode, the to-be-supported space is formed, then concrete is sprayed into the to-be-supported space through the shotcreting and anchoring assembly, a supporting structure is formed, it can be guaranteed that the concrete sprayed to the to-be-supported tunnel wall stays on the to-be-supported tunnel face, and the supporting effect is improved. The defect that concrete is wasted due to splashing is overcome, and the defects that concrete is splashed when the tunnel wall to be supported is supported in a concrete spraying mode, concrete is splashed, concrete is excessively consumed, and the concrete is excessively consumed are overcome.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel support device and a support method. Background technique [0002] When building a tunnel, it needs to go through excavation, initial support, secondary lining and other processes. In the related art, when the tunnel is initially supported, there is a serious problem of excessive consumption of shotcrete in the tunnel. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a tunnel support device and a support method, aiming at solving the technical problem of serious over-consumption of tunnel shotcrete during initial support of the tunnel. [0004] In order to achieve the above object, in a first aspect, the present invention proposes a tunnel support device, wherein the tunnel includes a tunnel wall to be supported and a face that is in contact with the tunnel wall to be supported; [0005] The tunnel support device i...
