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 measuring instrument and a method for measuring the weathering and spalling depth on the surface of short cylindrical stony cultural relics. The measuring instrument comprises a measuring curved plate and a dial indicator. The watch is used in conjunction with each other. The dial indicator includes a dial, a journal, a measuring rod, and a measuring head. The measuring head is at the front end, and the measuring rod, the journal and the dial are backward in sequence, and the measuring curved plate is in the form of a cylinder. The measuring curved plate is provided with a number of measuring holes, the lower edge of the measuring curved plate is fixedly connected to the support structure, the lower end of the support structure is fixedly connected to the short anchor rod embedded in the ground, and the journal is fixedly connected. Fixing the measuring tray, the outer surface of the measuring tray is a concave arc-shaped curved surface, and the measuring instrument has the advantages of high measurement accuracy, strong field adaptability, accurate measurement point positioning and high measurement point density after measurement.

Description

technical field [0001] 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 [0002] 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 cylindrical appear...
