Abstract

The invention discloses a spraying and painting integration tunnel construction device. The construction device comprises a spraying gun head, a screeding roller, a screeding brush, a rotating platform, a platform gear, a moving platform, an arc-shaped rail, a covneying pipe, a track gear, a ground rail, an inclined supporting frame, a stirrer, a screw propeller and an air pump. Raw materials are arranged in the stirrer, and newly-stirred sprayed concrete is conveyed to the screw propeller; under the pushing of the air pump, the concrete is conveyed to the spraying gun head through the conveying pipe and then is sprayed to the inner side of a tunnel through the spraying gun head; and the moving platform can move on the arc-shaped rail, and in the moving process, the screeding roller and the screeding brush can level concrete sprayed to the wall. One-section work is completed, then the whole arc-shaped rail can advance by a certain distance along the ground rail in the tunnel advancing direction, and next-section work continues to be completed. The device can effectively improve the construction efficiency of the sprayed concrete of the wall inside the tunnel, the construction effect is good, and the device is suitable for multiple tunnels.

Description

technical field [0001] The invention relates to a tunnel construction device, in particular to an integrated tunnel construction device for concrete spraying and smearing. Background technique [0002] Shotcrete technology is a construction method of spraying and pouring fine stone concrete with a pressure spray gun. It is often used for filling tunnel linings, walls, ceilings and other thin-walled structures or linings of other structures and protective layers of steel structures. [0003] Shotcrete technology has been used in construction for many years, and construction specifications and related technical regulations have been relatively mature. The application of spraying technology in concrete construction makes the construction of bridges and tunnel tops efficient and feasible. [0004] Despite the development and spraying of various concretes, up to now, in building construction, the concrete leveling on the top of buildings (including tunnels, bridges, etc.) still...
