Abstract

The invention provides a process and device for pouring concrete under pressure by a tunnel lining trolley. The device for pouring concrete under pressure by the tunnel lining trolley comprises a material distributing machine, a plurality of distributing pipes, material distributing joints and material discharging nozzles fixing devices. The distributing pipes are arranged on the lining trolley, and the distributing pipes comprise distributing pipe material feeding nozzles and distributing pipe material discharging nozzles, wherein the distributing pipe material feeding nozzles are arranged onthe rear side of the lining trolley and the distributing pipe material discharging nozzles are arranged inside the lining trolley close to working windows of the lining trolley; movable joints are arranged at the tail ends of the distributing pipes, so that material discharging nozzles can be switched and inserted into different working windows nearby; the material discharging nozzles fixing devices comprise fixing fixtures and discharge outlet fixtures; and the material distributing machine and the material distributing joints are connected together, and the material distributing joints canbe connected with the material discharging nozzles. The process and device for pouring concrete under pressure by the tunnel lining trolley has the characteristics of simple design, high degree of automation, intuitive and convenient operation and control, and has the advantages of improving working efficiency and saving working time, and thus herringbone slopes and cold seams can be effectively prevented.

Description

technical field [0001] The invention relates to a construction equipment and technology for tunnel concrete pouring, in particular to a technology and equipment for pouring concrete with a tunnel lining trolley under pressure. Background technique [0002] After the initial support of the tunnel construction is completed, the secondary lining is required, that is, pouring concrete. Since the trolley is a large-scale equipment, usually about 12 meters long, it is generally staggered on both sides of the trolley with multiple rows and rows. The windows are used for pouring concrete. Because of the easy coagulation and high density of concrete, it is usually connected to the pump of the mixer with a longer distributing pipe, and then connected to the pouring window with a shorter hose when it is close to the pouring window. In the traditional method of pouring concrete, usually after a window has poured concrete, the mixer is stopped, the pouring window is closed, and then acc...
