The reservoir drainage

typology of drainage systems

Besides spoiling the surrounding landscape, the presence of excessive ground moisture around the building can lead to the following consequences: flooding waters of the foundation, the penetration of moisture in the basement, which, in turn, leads to a gradual destruction of the structure of the building.All these factors underscore the need for a high drainage area, close to the building.

Depending on the product of the mechanism of excessive moisture migration from the soil drainage is divided into such types:

• Formation drainage.
• Ring drainage.
• trim drainage.

Each of the above types of this process has its own specific features.It will be a detailed analysis of each type of drainage process.

Formation drainage

This type of drainage is used in the most difficult areas, often as a supporting element for other types of drainage.Indicators for reservoir drainage can be:

• Availability pressure of groundwater.
• When other types of drainage systems can not provide a sufficient level of drainage.
• In the case where the ground water have a layered structure.
• When a building is determined the presence of a water lens.Produced

drainage system is also used in the case where the structure present in the room, which for its normal functioning, require maximum protection from excessive moisture.This may be the basements and other underground structures.

Also, this type of drainage system may be used as a preventive measure, even in the soil, which, according to its figures minimally exposed to groundwater.

Formation drain created by the following technologies.In places the necessary drying of the soil creates a layer whose thickness is about 300 mm.In some cases, the presence of moderate groundwater layer consists of gravel.In more complex cases, added to the layer of crushed stone sand layer in the proportions of 150 to 150 mm.

annular drainage system

This type of drainage used in areas without an explicit presence of groundwater.The purpose of using a circular drain drainage of melt and rain water during seasonal floods or rains.

Mount Technology annular drainage system:

• around the building to dig trench depth below the depth of the foundation and a thickness of not less than seventy centimeters.
• bottom of the pit should be at an angle based on the rate of 1 cm per meter.
• lower part of the pit is covered with sand and compacted.
• Then, the bottom of the trench is placed on top of the geotextile sand.
• the top layer of gravel is applied.After
• stacked pipes.The pipe must be below the foundation base.
• top of the tube is filled with rubble, and the fabric are wrapped with a layer of gravel inside the pipe.
• remainder of the trench is filled with sand and compacted.

should pay particular attention to the selection of pipes for the drainage of the ring.The strength of the outer skin must be quite high, and the diameter of at least 110 mm.Also do not forget that this type of drainage systems require a large number of inspection chambers.

This method of drainage is pretty easy to install and virtually no effect on the shaping of the landscape.The annular drainage system can serve as an auxiliary element, increasing Formation drainage.

MULTIDECK

drainage system is used in the presence of clay or silty soil.Construction of the drainage system is similar in its technology to the ring drainage.They take all the same manipulation in the ring system with the exception of some aspects:

• system is laid at a distance of 0.5 - 1 meter away from the house foundation.
• depth should correspond to the foundation thereof.
• All drainage pipes are connected and are discharged into the drain collector.

This type of drainage may be an additional element reinforcing the Formation drainage.

Thus, the article described types of drainage systems, their specific features and characteristics.There were also describes methods of installation of each type of drainage.
