Description

A road slope measurement tool

technical field

The utility model relates to a road side slope measuring tool.

Background technique

The slope of the road is generally expressed by the percentage method, that is, the percentage of the elevation difference between two points and its horizontal distance. The calculation formula is as follows: slope = (elevation difference/horizontal distance) × 100%. For example, if the slope is 30%, it means that when the horizontal distance advances 100 meters, the vertical height rises another 30 meters. During highway construction, it is inevitable to measure the slope, especially when measuring the slope of the gutter, usually at least two people are required to cooperate. One person uses a rod to measure the horizontal length, and the other measures the vertical height of the slope. It is convenient and inaccurate, which not only increases the difficulty of measurement, but also reduces the work efficiency of road construction, which is time-consuming and labor-intensive. In addition, what is used in the prior art is to first measure the angle of the slope with the help of an angle measurement tool, and then check the angle table to calculate the slope. The calculation is cumbersome and abstract, and the efficiency is low.

detailed description

In order to clearly illustrate the technical features of this solution, the utility model will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

As shown in Fig. 1, this embodiment highway side slope surveying instrument comprises a horizontal reference ruler 1, and an end of the horizontal reference ruler 1 is hinged with a side slope positioning ruler 2, and the outside of the side slope positioning ruler 2 and the horizontal reference ruler 1 The end is connected by a slope measuring ruler 3 vertically arranged with the horizontal reference ruler 1, the upper end of the slope measuring ruler 3 is fixedly connected with the slope positioning ruler 2, and the lower end of the slope measuring ruler 3 is slidingly connected with the horizontal reference ruler 1, and the slope measurement The inner side of the right angle formed by the ruler 3 and the horizontal reference ruler 1 is connected by an angle fixing mechanism, and a spirit level 4 is embedded on the horizontal reference ruler 1 along the length direction of the horizontal reference ruler 1, and the connection between the horizontal reference ruler 1 and the slope positioning ruler 2 The point is marked as point A, the connection point between slope positioning ruler 2 and slope measuring ruler 3 is marked as point B, the connection point between slope measuring ruler 3 and horizontal reference ruler 1 is marked as point C, and the slope measuring ruler 3 is provided with the following Point C is the scale 5 of the starting point, and each scale on the slope measuring ruler 3 takes the distance between point A and point C as the unit. Therefore, the scale value on the slope measuring ruler 3 is the slope of the side slope.

During use, the anchor rod 10 is inserted on the ground next to the highway, and the insertion depth of the anchor rod 10 is adjusted so that the bubbles in the spirit level 4 on the level gauge 1 are positioned in the middle of the level gauge 4, ensuring that the level gauge 1 is placed horizontally. Then, hold the outer end of the slope positioning ruler 2, adjust the angle between the slope positioning ruler 2 and the horizontal reference ruler 1, so that the slope positioning ruler 2 is placed on the surface of the slope, that is, the slope positioning ruler 2 is parallel to Slope placement.
