Abstract

The invention provides a double-side leveling ruler, which comprises a ruler body, wherein the ruler body comprises a first bar code leveling surface and a second bar code leveling surface arranged inthe length direction; the first bar code leveling surface and the second bar code leveling surface are respectively positioned at the two sides of the ruler body width direction; the ruler body can be used for simultaneously performing twice height measurement respectively through the first bar code leveling surface and the second bar code leveling surface arranged in the length direction; the first bar code leveling surface and the second bar code leveling surface are positioned at the two sides of the width direction of the ruler body; the two groups of measuring data can be obtained at thesame time; the observation times can be increased; through the processing on the two groups of height measuring results, the observation precision is improved; the error accumulation is avoided; themeasurement accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of engineering surveying, in particular to a double-sided leveling rod. Background technique [0002] Leveling, also known as geometric leveling, is a method of measuring the height difference between two points on the ground with a level and a leveling rod. Place a level between two points on the ground, observe the leveling rod erected on the two points, and calculate the height difference between the two points according to the reading on the ruler. Usually starting from the leveling origin or any known elevation point, the elevation of each point is measured station by station along the selected leveling route. [0003] In the traditional second-class leveling or higher-level leveling work, there is often the problem of over-limiting of the height difference closure, which cannot meet the needs of the project. For this, the method of re-testing the leveling route is usually used, which is not only time-...
