Problems solved by technology
[0002] At present, concrete feeding pipes are installed on both sides and top of the trolley for tunnel lining construction, and the concrete in the concrete pump truck is sent to the feeding pipe on the trolley through the pipeline to line the tunnel. The trolley needs to be equipped with a pouring trolley To drive the pipes to connect with different feeding pipes, the pipes used in ordinary tunnel lining trolleys use steel pipes. Due to the heavy weight of steel pipes, the pouring trolley needs to use rotating tools to drive the pipe outlets to connect with different feeding pipes on both sides and top of the trolley respectively. However, the steel pipe is heavy and has no elasticity or stretchability, which makes it difficult for the pouring trolley to drive the pipeline to move and rotate, so that the tunnel lining efficiency is not high; in addition, because there are many feeding pipes and their positions are different, the pouring trolley needs to be equipped with telescopic The pump tube is extended through the pump tube to connect with the feed pipe to connect to the feed pipeline. The pump tube is usually two sections of inner and outer tubes, and the outer tube is extended or retracted relative to the inner tube to realize the pump tube. During the distributing process, concrete is easy to enter the gap between the inner and outer pipe sections, which will wear the pipe section and cause difficulty in expansion and contraction, thus affecting the durability and stability of the pump pipe
