A measuring ruler and measuring method for measuring slope angles of different slopes

Abstract

The invention relates to a measuring ruler and a measuring method for measuring different slope angles. The measuring ruler includes a box body, a pulley, an iron ball, a power supply box, and a timing box. The top of the pulley is connected with the top plate of the box body, and the bottom plate of the box body is a magnet. Type conductive sheet, the pulley is wrapped with a conductive rope, one end of the conductive rope is fixed on the iron ball, the other end is connected to one end of the internal circuit of the power box through an external wire, and the other end of the internal circuit of the power box is connected to the external wire through an external wire. The bottom plate is connected, when the iron ball is in contact with the bottom plate, the internal circuit of the power supply box is connected, and the internal circuit of the timing box is disconnected. The top position of the box is provided with a pull-out pad to fix the iron ball, and the pulley is provided with a manual Rocking handle, the hand cranking handle extends out of the box. The measuring ruler of the present invention is simple in structure, simple and fast in operation, and easy to popularize. It can be used in high-frequency measurement occasions, so that the slope construction process is always in a controlled state, thereby ensuring the quality of the project.

Description

technical field [0001] The invention belongs to the field of engineering measuring instruments, and in particular relates to a measuring scale and a measuring method for measuring slope angles of different slopes. Background technique [0002] In civil engineering, water conservancy, transportation and other projects, such as the construction of highways, railways, airports, ports, dams and other projects, slope problems will be encountered. If the slope problem is not handled well, it will leave hidden dangers for the project. Once the damage occurs, it will bring huge losses to human life and property, which makes the slope stability analysis very important. In soil mechanics, whether the slope is unstable or not is determined by the slope stability coefficient, which is greatly dependent on the slope angle of the slope. Therefore, the measurement and control of the slope angle during construction is an important standard to ensure the quality and safety of the project. o...

Problems solved by technology

[0003] At present, theodolite or total station is often used in China to measure the slope angle, but this type of instrument has the following defects: 1. There are some unavoidable observation errors when operating the instrument, which reduces the measurement accuracy; 2. The measuring instrument requires professionals to operate. It is not easy to promote and use; 3. The operation of the above-mentioned measuring instruments is complicated, and when the workload is large, the efficiency is low
