Description

Technical Field

[0002] As the core assembly unit of shield construction, tunnel segments play a vital role. They are not only the inner protective barrier of the tunnel, but also bear multiple functions such as resisting soil layer, groundwater pressure and special loads. In order to ensure the high performance of tunnel segments, high-strength impermeable concrete is usually used in production, and concrete is poured in a strictly sealed environment with the help of professional segment molds to achieve precise shaping. This high-quality production process provides a solid guarantee for the safety and stability of the tunnel.

[0003] In the production process of precast concrete subway segments, the segment mold is an indispensable tool. The specific process is to inject concrete into the mold cavity, and after it solidifies, the concrete in the mold becomes the segment. In order to improve the quality of the segment, an important step after pouring is to smooth the surface. This process must be carried out before the initial setting of the concrete. The purpose is to smooth the outer surface of the segment and remove excess concrete on the surface to ensure the neat appearance of the segment and the accuracy of the size. This link is crucial to improving the overall quality of the segment.

[0004] Currently, segment plastering operations are mainly done manually, but manual plastering is labor-intensive, time-consuming and labor-intensive, and the overall efficiency of the process and work quality are limited. Utility Model Content
