Abstract

The invention relates to a road tunnel engineering construction method. The road tunnel engineering construction method adopts the following tunnel engineering construction device. The tunnel engineering construction device comprises a bottom plate, a rotating motor, a rotating shaft, a rotating support plate, an arc-shaped rotating plate, a rotating connecting frame and a cleaning mechanism. Thecleaning mechanism comprises a cleaning wheel, a cleaning shaft, a cleaning support plate, a sliding body, a sliding spring, a cover plate and a cleaning lifting rod. The construction method for roadtunnel engineering construction by adopting the tunnel engineering construction device comprises the following steps: S1, placing the bottom plate; S2, cleaning the side wall of the tunnel; S3, scraping by the cleaning mechanism; and S4, lifting the cleaning lifting rod. The problems that when pumice stones on the side wall of the tunnel are cleaned, certain safety hidden danger exists when the side wall of the tunnel is cleaned manually, the efficiency of cleaning the pumice stones manually is low, the pumice stones are not cleaned thoroughly and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a construction method for road tunnel engineering. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. The tunnel is constructed by manual excavation. After the tunnel is excavated, the side wall needs to be cleaned of pumice. The pumice on the side wall of the tunnel will fall during the tunnel spraying operation, causing safety hazards. [0003] When cleaning the pumice on the side wall of the tunnel, the pumice is often scraped off manually with a drill. The existing problems in cleaning the pumice on the side wall of the tunnel are as follows: [0004] There will be certain potential safety hazards when manually cleaning the side wall of the tunnel, and the efficiency of manual pumice cleaning is low, the pumice cleaning is not thorough, and the pumice in the concave position ...
