BBA Dutch Dewatering Solutions

Описание: In this video you find Dutch Dewatering Solutions with a BBA Wellpoint Dewatering System.

Wellpoint systems dewater water-bearing soils, such as sand and gravel, so that excavation and construction of foundations can proceed with a dry and stable ground foundation. They keep the foundation dry during rain and flooding. In addition, wellpoints can stabilize soil, relieve pressure for dams and levees, and help supply water for municipalities and industrial plants.

A wellpoint system encompasses a series of properly sized wellpoints that surround or run parallel to the site. Wellpoints are small-diameter tubes with slots near the bottom that are inserted into the ground. Before the excavation begins, these wellpoints are inserted into the soil and placed at the calculated spacing and depth by self-jetting into the ground.

Some soil conditions require predrilling or hole-punching and sand casing before the wellpoints can be installed. This can be accomplished with a jet pump, which has a discharge that should be piped to an area where it will not interfere with the contraction. The wellpoint tubes are then connected to a header pipe with risers and swings piping. A dewatering pump is then connected to the header piping, creating a vacuum that pumps the water in the soils of the construction site to the discharge area.

The BBA wellpoint system can 24/7 until the construction project is completed to ensure a stable foundation. A BBA wellpoint system and PT150 wellpoint pump are critical for a successful project.
