Tech/Engineering - Construction / Civil Engineering / Watertightness tests on sheet piling
Italian term or phrase: battente idraulico
"La pressione nella camera dipende quindi dal carico applicato e dal battente idraulico sulla presa di mandata alla camera."
This is a watertight chamber attached to a sheet pile along the banks of a canal in Venice, with the aim of testing that the connections between one sheet pile and the next are watertight.
Can anyone suggest what a battente idraulico is? (I have put hydraulic head but don't really understand what this means). Many thanks

water head
Explanation:
You can call it Hydraulic head if you want by water head is the usual term

It is about water pressure underground. On the surface you have Atmospheric pressure (14lb per sq inch) the weight of all that air on your "head". Go down ten metres underwater and that pressure double because of the extra water.

If you drill a hole in the ground let's say after at a depth of one metre you see water at the bottom. Go down two metres and you have one metre of water a Head of one metre.

Sometimes with a tunnel under a mountain the water head can be hundreds of metres with fantastic pressure 200 bar (that is 200 times the atmospheric pressure) like Niagara falls in the tunnel, if they don't drain it or block it well.

agree  Gad Kohenov: water head can be explained as colonna d'acqua
4 hrs

agree  Gian: yes; in this case it is a positive water head (negative w, h. in on the suction side)
5 hrs

agree  gvag: with reserve. To be precise, head and pressure coincide only under hydrostatic (no flow) conditions. The total hydraulic head is composed of pressure head, velocity head and elevation head. See http://en.wikipedia.org/wiki/Head_(hydraulic)
