Problems solved by technology

According to the analysis of this measurement method, the advantages are intuitive and convenient, but there are at least three shortcomings: first, the measurement accuracy of the steel needle is low
The actual measurement results show that this technology has the advantages of easy operation and low measurement cost, but there are two shortcomings: first, the measurement accuracy is not high (usually not higher than 0.5mm); The measuring surface involved in the measurement is very small (usually no more than 20cm 2 ), otherwise the measurement accuracy will be further reduced
Because the measurement surface involved in this method is usually very small, it is not only suitable for the weathering and spalling depth measurement of stone cultural relics whose overall surface shape is flat, but also can be used for the cylindrical stone cultural relics whose overall surface shape is the above-mentioned For the latter, it is difficult to complete the measurement of the weathered peeling depth of the overall surface of cylindrical stone cultural relics

Abstract

The invention relates to a measurement instrument used for the weathering stripping depth of a short cylindrical stone historical relic and a measurement method of the measurement instrument. The measurement instrument comprises a measurement bent plate and a dial indicator, wherein the measurement bent plate is matched with the dial indicator for use, the dial indicator comprises a dial plate, a shaft neck, a measurement rod and a measurement head, the measurement head is arranged at the foremost end, the measurement rod, the shaft neck and the dial plate are sequentially located behind the measurement head, the measurement bent plate is in a cylindrical shape, a plurality of measurement holes are formed in the measurement bent plate, the lower edge of the measurement bent plate is fixedly connected with a supporting structure, the lower end of the supporting structure is fixedly connected with a short anchor rod buried underground, a measurement support is fixed to the shaft neck, and the outer surface of the measurement support is a circular arc curved surface which is concave inwards. The measurement instrument has the advantages of being high in measurement precision, field adaptive capacity and measurement point density, accurate in positioning of measurement points and the like.

Description

[0001] technical field [0002] The invention relates to a measuring instrument and a measuring method for the weathering and spalling depth of the rock surface of short cylindrical stone cultural relics. Background technique [0003] For all kinds of stone relics (including short cylindrical stone relics), the peeling depth of the rock surface due to weathering is a big concern for cultural relics protection workers and engineering geoscience researchers, because the stone relics The degree of weathering and peeling of the surface and its related research will involve the long-term protection of stone artifacts made by ancient craftsmen. Considering that the cylindrical weathering spalling depth measuring instrument of the present invention is designed for short cylindrical stone relics, it is necessary to give examples of this type of stone relics for illustration: among the many stone relics in my country, there is a class with Stone cultural relics with a short cylindric...
