Deep well dewatering is a common method used to remove excess water from construction sites, mines, and other areas where water infiltration poses a problem. This technique involves drilling deep wells into the ground and using pumps to extract water from the surrounding soil and rock.
The process of deep well dewatering begins with a thorough site assessment to determine the depth and location of the wells. This information is essential for designing an effective dewatering system. Once the wells are drilled, submersible pumps are installed at strategic intervals to maximize water extraction.
Deep well dewatering has several advantages over other dewatering methods. Firstly, it can handle large volumes of water and is suitable for sites with high water tables. The depth of the wells allows for more efficient water extraction, as deeper wells can access layers of saturated soil that shallow wells cannot reach.
Additionally, deep well dewatering is a more sustainable solution compared to other techniques. By extracting water from deeper layers, it reduces the risk of contaminating nearby surface water sources. This is particularly important in environmentally sensitive areas where water quality is a concern.
Water supply by wells at the new place
For successful drainage of the place, it is necessary to take into account factors such as the depth and number of wells that will need to be drilled to achieve the desired level of groundwater lowering.
It is also necessary to take into account the peculiarities of the hydrogeological terrain, such as soil characteristics and conditions for the movement of groundwater.
The planning of pumping equipment installation points also plays an important role in this process.
The duration of the water treatment works depends on the amount of work required and the estimated time it will take to drain the site.
Before starting the construction of the facility, it is necessary to ensure the stability of the soil, which can be achieved by organizing an effective water supply system. This is especially important when working on the construction of various infrastructure facilities, such as trenches for communications, tunnels for railways, cars or mines.
However, deep well dewatering also has its limitations. The drilling and installation process can be time-consuming and costly, especially for large projects or sites with complex geology. In some cases, multiple wells may be required to adequately dewater the site, further adding to the overall cost.
Deep water reduction
The deep water supply system ensures the safety of construction through the use of filtration wells with centrifugal pumps. Drainage takes place inside a depression funnel formed when pumping water from a planned underground mine. High-quality sand and gravel sprinkling plays a key role in this system, preventing groundwater seepage through the slopes and the bottom of the pit. The depth of the filtration wells is more than 20 meters, which ensures effective water supply throughout the entire period of construction of the structure.
In conclusion, deep well dewatering is an effective method for removing excess water from construction sites and other areas. It offers numerous advantages, including the ability to handle large volumes of water, sustainability, and versatility in different soil conditions. However, it also comes with some limitations, such as high costs and the need for ongoing maintenance. Overall, deep well dewatering should be considered as a viable option for dewatering projects where other methods may be insufficient.
