Description

Technical Field

[0001] The utility model relates to the technical field of displacement meters, in particular to a quick-installation base for displacement meter accessories. Background Art

[0002] A displacement meter is a monitoring instrument for measuring the internal deformation of rock mass. The multi-point displacement meter is mainly composed of an anchor head, a transfer rod, a displacement sensor, a measuring base, a signal transmission cable, etc. It is widely used in geotechnical engineering and is generally installed by drilling holes in the rock.

[0003] At present, there are still some problems in the use of displacement meters. That is, the displacement meters are usually installed one by one as modular accessories, and then put into use. However, during this period, when the base is installed on the displacement meter, it is usually connected by direct insertion. The connection effect of this method is relatively general, and the base cannot be installed on the displacement meter quickly and reliably, resulting in separation when the base is subsequently inserted into the foundation pit. For this reason, we propose a displacement meter accessory quick installation base to solve the above problems. Utility Model Content
