It is used for the concrete lining construction of the inner wall of the tunnel. Concrete lining trolley is an indispensable non-standard product for the secondary lining in the tunnel construction process. It mainly includes simple lining trolley, full hydraulic automatic walking lining trolley and grid lining trolley. Full hydraulic lining trolley can be divided into side top arch type, full round needle beam type, bottom mold needle beam type, full round walking type, etc. In the construction of hydraulic tunnels and bridges, lifting slipforms, jacking slipforms and flip molds are also commonly used; at present, the rotary casting system or longitudinal casting trolley system is a widely popular casting method. The pipeline in the trolley is aligned by the telescopic tube, and the window or arch can be specified to be pressed to feed the material. This method is more efficient and the concrete diagram does not produce separation, but the pipeline is complicated, the later cleaning work is very cumbersome, and the left-right symmetrical material distribution cannot be implemented, which easily causes the trolley to be overloaded, thus forming a potential safety risk. The material distribution hopper needs to be frequently replaced before longitudinal walking, and the work efficiency is low. Utility Model Content
