Description

Technical Field

[0001] The present application belongs to the technical field of initial tunnel support construction, and specifically relates to a measuring and positioning device for controlling the installation spacing of steel arch frames. Background Art

[0002] Currently, during initial tunnel support construction, when the surrounding rock mass is fractured and self-stability is poor, steel arches are often required as support structures. Multiple steel arches are typically erected simultaneously. To ensure the spacing between adjacent steel arches meets design specifications, workers typically manually measure the spacing with a tape measure after each one is erected. Because the steel arches are not temporarily fixed and workers operate arbitrarily, it's impossible to ensure the spacing between adjacent steel arches is consistent. Furthermore, moving the steel arches after measuring the distance can also change their position, making it impossible to ensure consistent longitudinal alignment. This can lead to positioning errors during operation, resulting in tunnel construction quality failing to meet design requirements and impacting construction efficiency. Utility Model Content
