Description

Technical Field

[0001] The invention relates to an automatic lamination control device for a tunnel lining surface, belonging to the technical field of tunnel detection and maintenance. Background Art

[0002] To improve the mechanization and automation of tunnel operations, some organizations have developed trolleys for operations such as lining maintenance and waterproofing sheet installation. These trolleys are primarily constructed of arches and equipped with corresponding operating devices and structures. The arches are often designed to resemble typical lining cross-sections, such as a round arch or horseshoe. These operations, such as lining maintenance, waterproofing sheet installation, and lining inspection, typically require the operating devices to operate circumferentially, aligned with the lining surface. However, the cross-sectional shape and size of different tunnels vary, significantly impacting the trolley's performance and effectiveness.

[0003] Taking lining curing as an example, mechanized curing trolleys cure the lining concrete using spraying or misting. To ensure effective curing, it is recommended that the curing working surface maintain a fixed, close distance from the lining surface. However, curing trolleys typically have a fixed arch shape and dimensions, resulting in varying distances from the tunnel's crown, spandrels, and haunches. This limits their effectiveness in curing operations in tunnels of varying cross-sectional shapes and dimensions. Summary of the Invention
