Description

Technical Field

[0001] The utility model relates to the technical field of tunnel waterproof construction, in particular to an auxiliary device for laying a tunnel waterproof board. Background Art

[0002] Tunnel waterproofing requires laying waterproof panels. Their primary function is to prevent groundwater from eroding the tunnel interior. The panels are laid in sections, welded adjacent to each other, and then formed into a single piece. The panels are laid with appropriate tightness to ensure they fit snugly within the initial support structure and allow for sufficient clearance to accommodate deformation.

[0003] When using a hot-melt welding machine to perform double-seam welding on waterproof panels, manual assistance is required at the overlap due to the lack of a positioning device in the weld area before welding. Manual assistance is prone to displacement or shaking, resulting in inaccurate welding positions, and quality defects such as discontinuity and incompleteness in the welds. In order to prevent the waterproof panels from being displaced or damaged due to thermal deformation or external forces during the welding process, an auxiliary device for laying tunnel waterproof panels is proposed.
