An Angle Measuring Instrument Applicable to Soil Slope

Abstract

The invention discloses an angle measuring instrument suitable for a soil slope, which belongs to the field of surveying and mapping. The angle measuring instrument suitable for the soil slope comprises a fixed ruler; a stepping motor is mounted in the fixed ruler; a rotating wheel is fixedly connected to the power output end of the stepping motor; a movable ruler is fixedly connected to the rotating wheel; the top end of the movable ruler is fixedly connected with a fixed disc; a rotating shaft is rotationally connected to the fixed disc; a bearing is connected between the fixed disc and therotating shaft; a binding post is fixedly connected in the rotating shaft; the binding post is fixedly connected with a connecting rope; one end of the connecting rope away from the binding post is fixedly connected with a vertical cone; a laser lamp is installed in the vertical cone. The angle of the slope can be measured on the slope in two measuring and calculating modes, the obtained two setsof data are compared and verified with each other, high accuracy is achieved, the device can automatically run and can also be manually operated after being installed on the ground, and a user can conveniently smash all points on the slope for multiple times of measurement and calculation.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to an angle measuring instrument suitable for soil slopes. Background technique [0002] The side slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. The detection of the soil slope slope is a basic inspection item specified in the highway engineering quality inspection and evaluation standard. The side slope slope of the highway roadbed Depending on the geological and hydrological conditions and the height of filling and excavation of the subgrade, once the slope value is determined, if it exceeds the specified value during construction, it will cause the increase of the occupied area and the high economic cost of the cross section; if it reaches If it is less than the specified value, it will directly affect the stability of the subgrade and bury hidden dangers in quality. Therefore, accurate measurement of t...

Problems solved by technology

[0003] In the prior art, the measurement of the slope requires manual measurement with a flower rod and a tape measure to calculate the slope. Since the angles of the slope are often different, multiple measuring tools need to be equipped during the measurement, thus requiring two or more people to measure the slope. The construction personnel usually use the flower rod and the measuring tape to measure the corresponding size of the slope, and then calculate the slope according to the size. This method is inconvenient and inaccurate, time-consuming and laborious, which not only increases the difficulty of measurement, but also reduces the Improve the work efficiency of road construction
