Abstract

The invention provides a pouring system. The pouring system comprises an upper-layer pouring device, a lower-layer pouring device, a sliding assembly, a supporting frame and a grouting main pipe, thesupporting frame is arranged on the sliding assembly in a sliding mode, the upper-layer pouring device and the lower-layer pouring device are arranged on the upper side and the lower side of the supporting frame respectively, and the upper-layer pouring device and the lower-layer pouring device move along with the supporting frame; and the grouting main pipe selectively communicates with a grouting pipe of the upper-layer pouring device or a grouting pipe of the lower-layer pouring device, so that pouring operation of the upper-layer pouring device or the lower-layer pouring device is realized. The upper-layer pouring device is configured with arch crown pouring for pouring, the lower-layer pouring device is configured with arch wall pouring for pouring, and the lining quality is guaranteed through layer-by-layer windowing pouring. The invention further provides a lining trolley. Visual management of pouring operation of the lining trolley is achieved.

Description

technical field [0001] The invention relates to the technical field of lining trolleys, in particular to a pouring system and a lining trolley. Background technique [0002] The secondary lining construction of railway and subway tunnels is an important process and link in tunnel construction. The construction level of tunnel lining directly affects the quality, construction speed, construction cost and management of the tunnel during operation. Since the lining trolley was introduced into China in the 1980s, it has effectively reduced the labor intensity and improved the operation efficiency of the secondary lining construction, and has become the main equipment for the tunnel secondary lining construction. With the advancement of science and technology in our country and the trend of increasing tunnels year by year, the development of lining trolleys has shown a trend of increasing year by year in recent years, showing great competitiveness in the field of tunnel lining co...
