Vertical guided measurement device and guided measurement method thereof

Abstract

The invention relates to measurement equipment on a reservoir dam, in particular to a vertical guided measurement device and a guided measurement method thereof. According to the device, a measurement applying ladder and a measured ladder are respectively mounted on a measured plumb wall surface; the measurement applying ladder is provided with a plurality of measurement applying platforms for placing digital leveling instruments; a plurality of measurement points are mounted on the plumb wall surface, which is closed to the measured ladder, from bottom to top; level bar code rulers are arranged on the measurement points in a measurement process. The method comprises the following steps of: mounting a plurality of the measurement points on the measured plumb wall surface and starting to place the level bar code rulers from the bottommost measurement point; utilizing the same digital leveling instrument to measure readings obtained by respectively placing the level bar code rulers on the two adjacent measurement points; subtracting the two reading values to obtain a height difference between the two adjacent measurement points; sequentially measuring the height difference between the two residual adjacent measurement points and adding all height difference values to obtain the height difference between the uppermost end and the bottommost end of the measured plumb wall surface. The device provided by the invention is simple in structure, is not influenced by weather and has a good protective effect; and the method provided by the invention has the advantages of simplicity in operation, low cost and accuracy in measurement.

Description

technical field [0001] The invention relates to measuring equipment on a reservoir dam, in particular to a vertical measuring device and a measuring method. Background technique [0002] With the advancement of technology and the continuous improvement of management level, digital level has become an instrument that is widely used in the measurement of many reservoirs. [0003] Reservoir dam construction often has a vertical plane structure. In order to monitor the safety of the dam construction, especially the needs of deformation monitoring, a tower ruler or an ordinary steel ruler and an optical level are usually used for manual reading measurement; The indium steel ruler cannot play a role in this structure (especially when the height difference is greater than the ruler length), or in this specific dam construction structure, the bar level bar code ruler and digital level cannot play their electronic measurement. The function and accuracy can only be measured by manual...
