Description

Slope Gauge

technical field

The utility model relates to a tool for measuring the gradient of an inclined surface, which is mainly used for measuring the gradient of inclined surfaces with slopes such as roadbeds, embankments, ditches and mountains.

Background technique

The slope of roadbed, embankment, ditches and other slopes is an important control and detection index in both construction and maintenance construction in the future. At present, the method of measuring the slope generally adopts the ruler method and the level method. The ruler measurement method is relatively simple and intuitive, but it is greatly affected by human estimation and has low measurement accuracy. The data measured by the level meter method is more accurate. The specific method is: first use a steel tape to measure the slope length of the measured slope, and then use a level gauge and a tower ruler to measure the height of the two ends of the slope length, and calculate the height of the top and bottom of the slope length. Then use the Pythagorean theorem of the right triangle to calculate the horizontal projection of the oblique length, and the ratio of the horizontal projection to the height difference is the slope value. The level method measurement is also restricted by many factors. The longer the slope and the steeper the slope, the more difficult the measurement and the more workload. For example, there are obstacles on the slope such as trees and rocks that hinder the sight or passage. The accuracy of the measurement will also decrease. At the same time, the level method also has some other disadvantages. If it is necessary to use multiple tools including a level, a tower ruler, a steel tape measure, and a calculator, it takes up a lot of people and the measurement efficiency is low. The level method is difficult to apply to high-frequency measurement occasions, and in the construction of roadbeds, embankments, ditches, etc., in order to keep the slope in a controlled state from time to time, frequent detection of the slope slope is just indispensable.
