Wellpointing
The wellpoint system is one of the most versatile of dewatering methods. It involves installing or jetting a series of closely placed small wells (wellpoints) spaced along a trench or around an excavation site, all connected to a common header that surrounds the excavation and attached to one or more wellpoint pumps.
This system is very effective in a wide range of soils from fine silted sand to coarse gravels, and is most suitably implemented for relatively shallow excavations up to approximately 6 metres deep in stratified soils. Due to the vacuum limitation of the pump, excavations that are deeper will require multiple stages of wellpoint systems.
At Carrier Rental Systems Asia, we understand requirements may sometimes vary drastically from one job to another. Whatever your job requirements, we have the equipment available to meet your needs.
** All equipment can be combined to provide the necessary flow capacity requirements.
Factors that must be put into considerations when designing a wellpoint system are:
- The physical layout
- Adjacent areas
- Soil conditions
- Permeability
- The amount of water to be pumped
- Depth to imperviousness
- Stratification
- Friction losses developed in the suction side system
