Description

Technical Field

[0001] This utility model relates to the field of tunnel initial flatness detection technology, and in particular to a tunnel initial support surface flatness detection ruler. Background Technology

[0002] A tunnel initial support surface flatness measuring ruler is an engineering surveying tool specifically designed to inspect the flatness of the initial support (initial support) surface of a tunnel. Its core purpose is to assess whether the flatness of the initial support surface meets design specifications, ensuring the quality and safety of subsequent construction. Main Features and Principles: Basic Principle: Measures the gap or deviation between the initial support surface and a standard plane through contact or non-contact methods. Common methods include using a ruler and feeler gauge to measure the gap value, or using a high-precision sensor to directly acquire data. Tool Types: Traditional Tools: Such as a 2-meter straightedge with a feeler gauge, suitable for general inspection, but may pose safety hazards in high-risk areas such as the tunnel arch. An existing tunnel initial support surface flatness testing ruler is not convenient for operators to adjust its actual height according to the actual ground position when operating the ruler at different work locations, thus affecting the stability and accuracy of the ruler.
