Piezometers

The installation of piezometers is used to control water quality, vents of steam, groundwater levels and estimated / actual thicknesses of overdrained chemical elements. The main features of these piezometers are as follows:

• Drilling diameter: 98 mm minimum. It should ensure sufficient annular space between the pipe and drilling of groundwater for siliceous gravel filter.
• Piezometric slotted pipe section with light from 0.25 to 0.50 mm and blind stretch. The unions are threaded sections without altering the exterior or interior diameters. Diameters of 1 “, 1½”, 2 “, 2 ½”, 3 “and 4”.
• Installing screw plug on bottom and head.
• Filling the annular space between the pipe and the walls piezometric survey with siliceous gravel or 3-5 mm H grooving and bentonite pellets in the blind stretch stretch.
• Possibility of prefilter attached to the tube gravel.
•  Sealing the well with a layer of bentonite and cement mortar rest.
• Installation of watertight manhole cover dichromate anticorrosive steel finish that will allow the passage of vehicles.
• Piezometers development by self-priming pump, submersible pump type Waterra Whale or another suitable system at the underground water level detected. It includes suction discharge pipe and adequate pumping system according to the piezometer diameter.
