Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, specifically an auxiliary device for measuring the height of a prism. Background Technology

[0002] In engineering construction in mountainous areas with significant topographic relief, the accurate establishment of elevation benchmarks is crucial. Due to the large variations in mountainous terrain, trigonometric leveling is commonly used to establish high-precision elevation benchmarks.

[0003] In field surveying, total stations are frequently used in conjunction with prisms for trigonometric leveling control measurements. During the surveying process, the prism height needs to be accurately measured and entered into the instrument or handheld device for subsequent operations. Since prisms are typically erected directly above the control points using a base and legs, accurately measuring their height presents significant challenges. Therefore, it is essential to utilize a portable tool for precise measurement of the prism's vertical height.

[0004] The traditional method for measuring prism height involves aligning and leveling the prism base, then using a steel tape measure to measure the centerline from the top of the measuring point to the side of the prism target. Since the measured dimension is the slant height of the prism center rather than the vertical height, this method is inaccurate and introduces errors into the accuracy of elevation control measurements. Furthermore, because the steel tape measure is flexible, it can twist and deform when passing over the base, requiring operators to constantly adjust the direction of the prism target, making the operation inconvenient. Therefore, an auxiliary device for measuring prism height is proposed. Utility Model Content
