It is critical to remove surplus groundwater from your construction site. It not only provides a safe working environment for the workers, but it also aids in the security of the building under construction. Construction sites can be time-consuming and expensive to dewater. However, it is one of those things that cannot be avoided, particularly on a flooded building site.
It is critical to have a competent construction dewatering plan. It will aid in keeping the project under budget and on schedule.
A construction site can be dewatered using a variety of methods. Every job has a method, and each method should be carefully evaluated before being chosen. Choosing the appropriate dewatering process can be difficult, but with the right guidance, it should be a piece of cake.
What exactly is dewatering?
Dewatering is the process of removing surface water, sometimes known as groundwater, from a construction site. This is accomplished by lowering the water table. Due to accumulated water in holes and trenches, construction dewatering is commonly utilised on building sites. This pooled water can also be found in areas with a low water table or a low slope. To ensure worker safety, this gathered water must be evacuated.
To remove groundwater from your construction site, you can use one or a combination of the following methods:
The method of well-points
This is one of the most efficient ways to remove groundwater. Several wells are aligned along the excavated area in this manner. The well point is linked to a riser pipe, which is linked to a common header pipe and vacuum pump. Water is released from the site after sufficient treatment to remove contaminated and hazardous contaminants. The depth of the well must be up to 5 or 6 metres for this system to function properly.
Wells, Eductor
The eductor well method and the well-point method are similar. The key distinction is that eductor wells employ high-pressure water to extract water from the well-points rather than a vacuum. The eductors circulate high-pressure water in the bottom of each well, causing a pressure drop that draws water through the rider pipe.
When the ground has a poor permeability material, the eductor well approach is best applied. Eductors are primarily utilised to help stabilise the excavation area’s side slopes and soil.
Method of Flood Control
If a heavy shower of rain and storms causes problems at your construction site, this strategy is frequently used. Flood control is a means of reducing or preventing the adverse impacts of floods, such as runoff and excessive rainfall. As a construction, tunnelling, or mine site manager, you must be prepared for potential site flooding.
The ground becomes sodden and unstable as the water table rises, posing a safety danger to construction workers.
It is critical that construction companies have adequate flood protection and are prepared to act promptly in these situations.
Conclusion
Construction professionals must learn about industry laws and regulations and be skilled enough to complete construction projects in order to grow and survive in an environment where more and more buildings are developed and erected.
