Wellpoint systems are used to lower groundwater levels to provide stable working conditions in excavations and are particularly suited to dewatering for shallow foundations and trench works. This method is capable of dealing with a wide variety of ground conditions, particulary suited to non-cohesive soils.
A wellpoint system consists of a closely spaced series of small-diameter shallow wells. The wellpoints are connected to a common headermain and are pumped with a high-efficiency vacuum dewatering pump.
The well points are usually installed using a jetting tube and pump. The two combined are a rapid and cost effective method of installing disposable wellpoints; the use of filters reduces undermining and produces clean discharge water, this system can be designed to suit most excavations.
The well point system is suitable for many types of civil works such as:
- Excavations for basements and foundations of Buildings
- Foundations of Bridges & Underground tanks
- Laying of deep sewer lines
- Excavations and lining works for canals and channels etc
- Tunnel work
- Sub-ways (Tube Railway etc.)
- Reclamation of land
- Water supply
- Excavations for basements and foundations of Buildings
