Technical Field

[0001] The utility model relates to a garbage clearing and transporting device in shield construction, in particular to a sprocket type electric garbage clearing and transporting trolley used in the shield construction process. Background Art

[0002] Considering the internal structural design of ultra-large diameter shield tunnels, a box culvert structure is generally set up at the bottom of the tunnel. In order to reduce the overall weight of the box culvert and the bonding effect between the box culvert and the pipe segments, the bottom surface of the box culvert is designed to be a hollow structure, that is, a plurality of arc-shaped hollow grooves are opened on the bottom surface. Concrete needs to be filled in the hollow area later, and the concrete filling time is after the shield has advanced a certain distance. When pouring concrete, in order to ensure the pouring quality, the mud on the bottom surface of the box culvert and the hollow area needs to be cleaned before pouring concrete. Since the bottom surface of the box culvert is equipped with multiple grooves at intervals and is not a flat surface, conventional transport carts cannot move normally on the bottom surface of the box culvert. The wheels are easily stuck in the groove area, and it may also cause rollover, resulting in the inability to efficiently transport the cleaned garbage. In order to improve construction efficiency and safety, it is necessary to design a special garbage collection and transfer cart. Summary of the Invention
