Water transfer channel

Water transfer channel

Preventing the loss and pollution of fresh water sources and its correct and safe transfer to the places of consumption without changing the quantity and quality have always been discussed in civil and geotechnical engineering. The construction of water transfer channels that are responsible for transferring fluid from the main source to the places of consumption, especially in unfavorable environmental conditions such as the condition of the bed soil, difficult access, weather conditions and many other factors that make the construction of a durable and high-quality water transfer channel necessary. has constructed.

The traditional methods of constructing a water transfer channel, whether covered with dense clay or impermeable concrete, on the one hand, are not applicable on all kinds of soils such as chalky, sandy, silty and corrosive soils, and for this reason, the heavy costs of replacing the soil It imposes on the project, and on the other hand, it is quickly destroyed by environmental factors and brings maintenance and repair costs during the system's operation period. The difficulties of compaction and correct acoustic performance of these materials, which strongly affects their permeability and durability, in addition to the sensitivity of these methods to changes in temperature and moisture percentage, ice packs, plant growth, animal attacks, microscopic factors, and many others, the need to provide a reliable method and With durability, it has made the construction of the water transfer channel inevitable.

Therefore, the construction of the water transfer channel using geosynthetic materials (geomembrane, geotextile and geocomposites) has attracted the attention of those involved in construction projects all over the world today as a substitute for traditional and well-known old methods. The construction of the water transfer channel by geosynthetics has many advantages, which will be mentioned below.

The advantages of constructing a water transfer channel by geosynthetics:

Acceleration of channel execution time

No time limit for project implementation

Considerable reduction of costs

No need to replace the soil, especially problematic soils

Ease of installation and construction in the shortest time and the highest quality

Very high impermeability and insulation

No growth of weeds, reeds, algae, and moss along the canal route

Increasing the speed and efficiency of water transfer

Construction stages of the water transfer channel

Mapping and collecting basic information of the water transfer channel

Channel design and calculation of slopes along the route of the water transmission channel

Earth operations (excavation or embankment after leveling the surface) according to the volume of water passing through the channel

Preparing the bed (regulating, compacting, etc.) and leveling the walls and floor

Piping (inlet, outlet, overflow, etc.)

Calculation of required geosynthetic materials and its transfer to the canal route

Spreading the geotextile protective layer (if needed)

Cutting polymer sheets according to the geometry and dimensions of the channel

Complete installation and sealing of the water transfer channel

Dewatering and final control of the canal
