Description

Technical Field

[0001] The present application relates to the field of tunnel construction equipment, and in particular to a tunnel primary support flatness repair device. Background Art

[0002] Tunnels are engineering structures buried in the ground. Tunnels can be divided into traffic tunnels, hydraulic tunnels, mining tunnels and municipal tunnels. During the construction of tunnels, the flatness of the inner wall of the tunnel must be guaranteed. During the initial support shotcrete construction of the tunnel, due to the obstruction of structures such as steel mesh, steel frame and connecting steel bars, the shotcrete process cannot be carried out continuously and evenly. Therefore, under normal circumstances, the flatness of the initial support surface cannot meet the acceptance standard at one time, and flatness treatment is required.

[0003] Prior art CN216741552U discloses a tunnel initial support flatness finishing device, which includes an initial support flattening plate and an overshoe connected to the initial support flattening plate, and the overshoe is used to be installed on an installation borrowing carrier. The overshoe includes a sleeve and a fixed ring spaced apart in an upper and lower manner, the diameter of the sleeve is smaller than the diameter of the fixed ring, and the sleeve and the fixed ring are fixedly connected by a number of spaced connecting rods. The installation borrowing carrier is inserted into the overshoe through the fixed ring, and the overshoe is connected to the installation borrowing carrier by inserting two symmetrically distributed blocks between the overshoe and the installation borrowing carrier. The tunnel initial support flatness finishing device is installed on the installation borrowing carrier, and the installation borrowing carrier can be a spray gun nozzle of a wet spraying manipulator or a long rod, and the installation is convenient and quick.

[0004] With regard to the above-mentioned related technologies, the inventor believes that the above-mentioned tunnel initial support flatness finishing device will encounter resistance during the flatness finishing process, and the clamping block connected between the overshoe and the installation borrowing carrier will be displaced due to the force, thereby reducing the connection stability between the overshoe and the installation borrowing carrier, thereby reducing the efficiency of the flatness finishing.
