Abstract

The invention relates to a subway duct piece arc surface troweling device. A three-dimensional movement mechanism is installed on a portal frame, a troweling machine head is installed on the three-dimensional movement mechanism, the troweling machine head is provided with a troweling flat plate, the troweling flat plate is a circular arc-shaped plate which is the same as the circular arc surface of a subway duct piece, and the three-dimensional movement mechanism drives the troweling flat plate to be arranged coaxial with the circular arc surface of the subway duct piece; and after the troweling flat plate is driven to move in the width direction of the arc surface of the subway duct piece, the arc surface of the subway pipe piece is troweled in the moving process of the troweling plate, the width of the same subway iron pipe piece is far less than that of the arc length, the troweling time of the subway pipe piece is shortened, the production time of the subway pipe piece is shortened, and the production efficiency of the subway pipe piece is further improved.

Description

technical field [0001] The invention relates to the technical field of subway segment production equipment, in particular to a smoothing device for the arc surface of a subway segment. Background technique [0002] The shield tunneling method is a fully mechanized construction method in underground 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 advancing rapidly. The shield segment is the main assembly component of the shield tunneling method. 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. [0003] The manufacturing process of the shield segment for subway tunnels is as follows: after the concrete material is loaded into the steel mold and the vibration is completed, the operato...
