Description

Technical Field

[0001] The utility model relates to the technical field of subway pipe segments, in particular to a device for plastering the outer arc surface of a subway pipe segment. Background Art

[0002] The shield method is a fully mechanized construction method in dark excavation construction. It has the characteristics of fast construction speed, stable tunnel quality, and less impact on surrounding buildings. This method has been widely used, and the development of related technologies is also increasingly rapid. The shield segment is the main assembly component of the shield method construction. The quality of the segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. The production process of the shield segment for the subway tunnel is as follows: after the concrete material is loaded into the steel mold and vibrated, the operator will perform water collection and finishing work on the outer arc surface of the segment, pat the concrete surface, and scrape off the excess concrete, and finish and finish the concrete surface. After the concrete solidifies, the arc surface of the segment is polished. The traditional smoothing method is that the operator holds a smoothing tool to smooth the arc surface. The flatness of the manually smoothed arc surface is not high, and the quality of the segment is poor, which affects the overall quality and safety of the tunnel. In addition, it takes a long time to manually polish the arc surface of the segment, and the efficiency is low.

[0003] When the traditional subway segment outer arc surface plastering device is used for plastering, a trowel plate is generally used for plastering. When the trowel plate is plastered, excess concrete will be scraped off by the trowel plate, and the scraped concrete will slide along the trowel plate to both sides of the trowel plate, causing the concrete to slide to the periphery of the subway segment mold base, affecting work efficiency and not allowing staff to clean up.
