dräneringsgångar

Dräneringsgångar, or drainage galleries, are underground structures designed to collect and convey groundwater away from sensitive areas. They are typically constructed using concrete or masonry and are characterized by perforated pipes or channels that allow water to enter. The primary purpose of dräneringsgångar is to lower the water table, thereby preventing issues such as waterlogging, soil erosion, and damage to infrastructure.

These galleries are commonly employed in civil engineering projects, including the construction of roads, railways, and buildings, particularly in areas with high groundwater levels or unstable soil conditions. They play a crucial role in maintaining the stability and longevity of these structures by reducing hydrostatic pressure and improving the load-bearing capacity of the surrounding soil. In agricultural settings, dräneringsgångar can be used to improve soil drainage, making land more suitable for cultivation and preventing crop damage due to excessive moisture.

The design and installation of dräneringsgångar require careful consideration of geological conditions, hydraulic requirements, and the specific purpose they are intended to serve. The collected water is typically channeled to a natural watercourse, a storm drain system, or a reservoir for reuse. Regular inspection and maintenance are essential to ensure the continued effectiveness of dräneringsgångar, preventing blockages and structural deterioration.
