DWLR
DWLR (Piezometers) are the geotechnical sensors that are used to
measure water level in the ground. It is designed
to measure water Water in the soil, earth/rock fills, foundations, and
concrete structures.
Considered one of the most important geotechnical
monitoring instruments, it’s interesting to study as well. Let’s discuss more
about piezometers, their types, working principles, applications, and functions
in detail.
Piezometers are pressure
transducers that are installed beneath the ground to measure the sub-surface
piezometric level within groundwater level, soil, or rock. Now that you are
well-versed with the piezometer definition, let’s move forward to understanding
its usage in the geotechnical domain.
Proper evaluation of pore pressure helps in monitoring
the behaviours after construction and indicates potentially dangerous
conditions that may adversely affect the stability of the structure, its
foundation, and its appurtenant.
It also provides basic data for design improvement that
will promote safer and more economical design and construction. The Casagrande piezometer is
considered the simplest form of piezometer. It consists of a Casagrande tip
connected to the lengths of the extension pipe. The water level inside the pipe
is measured using the diameter.
However, the vibrating wire piezometer is most commonly used because of accurate results and higher reliability.
