Well pointing is of great importance during the execution of construction works. When carrying out construction projects, it is important to be able to carry out the work in a dry construction pit. In these cases, well pointing is usually necessary.
Every project requires specific dewatering. We rely on various methods for this and we have an extensive machine park. In addition to this, we carry out a comprehensive study via computer simulation to estimate the risk of each dewatering technique in that specific situation, and we can provide or recommend appropriate safety measures.
Well pointing using vertical drains is a technique in which vertical drains are drilled into the ground manually or mechanically around the construction site. They get connected via a common suction line to a piston pump that pumps up the incoming groundwater. This technique is mainly used for the drainage of construction pits or sewerage trenches to a depth of four meters below ground level.
This dewatering method avoids the bursting of excavation pits and can easily be combined or expanded with other methods.
For this method, a hole is bored at a depth of twenty to thirty meters below ground level. A PVC filter is built into the well hole and is poured over with filter gravel. An underwater pump is placed in the well hole.
Dewatering with deep wells is a method suitable for achieving deep groundwater reductions at large construction pits such as, for instance, underground car parks, tunnels or construction projects in an urban environment. This method is suitable for depths from 4 meters and can normally be applied to unlimited depth.
Because dewatering influence is greater with this method, the risks on the environment are also greater. That is why we always carry out a thorough preliminary investigation into the risks in order to take the necessary protection measures in time.
Deeps wells can be performed in combination with return dewatering to minimise the risk of damage to neighbouring buildings.
This method is necessary in some cases to compensate for the possible unfavorable consequences of groundwater reduction. Well pointing whereby a substantial groundwater reduction is achieved can cause considerable settlements in subsoil that is not strong enough. This can cause damage to surrounding buildings. In such cases and in order to prevent those risks, return dewatering is often used.
A portion of the pumped-up groundwater is infiltrated back into the subsurface via the so-called return wells. Groundwater level thus remains at its natural level in the at-risk zone. There are no soil settlements and consequently no damage can occur.
With this well pointing method, a drainage pipe is milled into the subsurface using a deep-draining machine. This drain is then connected to a piston pump via a flexible blind suction line. Through this method, incoming groundwater is pumped away.
This method is a great solution for pumping pipe slots in open fields, such as pipelines. It is most suitable for depths going up to 4 to 5 meters or in case of impermeable clay layers in the soil.
