Description

Novel string type multipoint displacement meter tube Technical Field The utility model relates to the field of string type displacement meters, in particular to a novel string type multipoint displacement meter tube. Background The string type multipoint displacement meter is suitable for being buried in structures such as earth dams, earth embankments, slopes, tunnels, foundations and the like for a long time, displacement, settlement, strain, slippage and the like of multiple parts of deep layers in the structures are measured, the temperature of buried points is synchronously measured, and the string type multipoint displacement meter can be divided into string type single-point displacement meters and string type multipoint displacement meters according to the number of measured points. A chordal multipoint displacement meter is a device that monitors multiple measurement points simultaneously. The multi-point monitoring of the structure is realized by arranging a plurality of independent string type single-point displacement meters on the same plane.
