Embodiment 1

[0123] Embodiment 1 is a kind of soil displacement measurement device, and this soil displacement measurement device comprises:

[0124] Cylindrical hollow shell;

[0125] an outer ring magnet slidably arranged on the outer surface of the cylindrical hollow housing in such a manner that the cylindrical hollow housing is inserted through the central cavity of the outer ring magnet;

[0126] an inner magnet, the inner magnet is arranged in the cylindrical hollow shell;

[0127] a suspension assembly that retains the inner magnet relative to the cylindrical hollow housing such that the inner magnet is suspended within the interior space of the cylindrical hollow housing; and

[0128] a strain-gauge element provided to the region of the suspension assembly,

[0129] Wherein, the relative movement between the outer ring magnet and the cylindrical hollow shell along the longitudinal axis of the cylindrical hollow shell makes the outer ring magnet and the inner magnet work together...

Abstract

A soil displacement measurement device may include a cylindrical hollow housing; an outer ring-magnet slidably arranged on an exterior surface of the cylindrical hollow housing; an inner magnet disposed within the cylindrical hollow housing; a suspension arrangement suspending the inner magnet within an interior space of the cylindrical hollow housing; and a strain measurement element provided toa region of the suspension arrangement. A relative movement between the outer ring-magnet and the cylindrical hollow housing along a longitudinal axis of the cylindrical hollow housing may cause the outer ring-magnet to coact with the inner magnet in a manner such that a magnetic force between the two magnets changes a corresponding strain at the region of the suspension arrangement. The change inthe strain may be detected by the strain measurement element as a measure of the relative displacement of the outer ring-magnet along the cylindrical hollow housing.

Description

technical field [0001] Various embodiments generally relate to a soil mass displacement measurement device. In particular, various embodiments generally relate to a soil displacement measurement device for measuring horizontal soil displacement and / or vertical soil displacement. Background technique [0002] Soil displacement monitoring is very important to ensure safety, especially in construction sites. The soil displacement may be in the form of a horizontal soil displacement, such as a landslide, or a vertical soil displacement, such as settlement or heave. [0003] When monitoring horizontal soil displacements, displacement measurement tools such as inclinometers are often available. Inclinometers can be used to measure landslides due to heavy construction activity, heavy precipitation, ground settlement, etc. For example, a soil mass may experience forces from an excavation / tunneling site towards a nearby area and thus move in a certain direction. The slope of the ...
