Description

Technical Field

[0002] During road slope construction, surveyors are often required to cooperate with engineering machinery to check the slope and direct the machine operators to dig and fill the earth. Although this form of operation can complete the work, its work efficiency is low and the operation is difficult. However, there is currently no special measuring instrument suitable for slope inspection during construction.

[0003] Although other instruments for measuring slope used in field geological exploration or engineering construction can also be used for slope inspection, their applications are mostly limited: 1) Conventional semicircular slope meters determine angles through a vertical line, are large in size, and the external weight line is easily pulled and hung, and the dial is easily dirty. Handheld observation requires side observation and cannot record. 2) Special infrared observation instruments can only emit in a horizontal straight line and cannot set the emission angle according to the vertical direction. They are large in size, heavy, and expensive.

[0004] Therefore, it is of great practical significance to develop a road slope detection device with easy operation, simple structure, small size and low cost. Utility Model Content
