Drainage tunnel is designed to collect and discharge storm and sewer (previously treated) water. The design is lightweight and can be installed in one or more rows to form a large drainage field space. Additionally, plastic perforated wells can be used, which are filled with a layer of expanded clay to increase the degree of wastewater treatment.
Dignity
Drainage tunnels and blocks have many advantages, among which the following are worth noting:
- Plastic construction is not affected by chemical aggressive compounds, rotting and corrosive phenomena.
- Due to its low weight, there are no significant costs for transportation and installation, and it is also worth noting that there is no need for a lot of excavation.
- Simple installation is ensured by preliminary calculation of the configuration, volume of products and selection interms and conditions.
- Devices differ in capacity and the ability to transport a large amount of storm and sewer drains.
- Free air exchange that does not interfere with the vital activity of bacteria.
- High structural strength, making it possible to use in areas with traffic load.
Installation
A large amount of precipitation and the proximity of the aquifer can lead to the destruction of buildings and the death of plants on the site. Carrying out appropriate measures can protect against the negative effects of excessive moisture. The drainage tunnel provides high-quality drainage of the territory. Installation does not cause any particular difficulties and consists of the following steps:
- Dig a trench of suitable length, into which a layer of sand and gravel is poured.
- Next, the required number of blocks is stacked.
- In some cases, additional insulation is made with special materials, after which the structure is covered with soil.
Application
At present, there are no alternative devices that are highly effective. The drainage tunnel is suitable for agricultural and landscaping applications, and is also used in low-rise and high-rise construction and road construction. It has gained the greatest distribution among the owners of suburban areas as a method of draining the territory.
The need for a closedthe drainage system occurs when the site is in a lowland or in case of high waterlogging. Its arrangement is also recommended when planning the construction of a house with a basement. According to many experts, drainage is required in most areas in the middle zone of our country. To increase efficiency, Graf and Drening drainage tunnels are installed as part of the drainage system.
What you need to know
The drainage system is being designed simultaneously with the arrangement of the suburban area. In this case, it is necessary to take into account the main factors, including the presence of a basement and an underground garage, the type of soil, the location of natural reservoirs in the area, the average rainfall, and the relief.
Drainage of the territory is possible through two methods:
- Deep drainage system. It consists of underground channels and is designed to divert water beyond the boundaries of the site and reduce the amount of groundwater.
- Surface drainage is a point and linear drainage system that collects melt, rainwater and consists of modular channels. It allows you to quickly remove precipitation from a large area. The calculation of the number of drainage tunnels is made taking into account the height differences on the site, soil type, soil filtration coefficient and other parameters.
Features
Self-arrangement of drainage is within the power of any person, due to the fact that it does not require the usespecial tools. Convenience of application is reached by spaciousness, simple installation and easy transportation. Infiltration blocks, used in conjunction with plastic septic tanks, also allow the liquid to be diverted to a special drainage space. Before purchasing products, you need to calculate the total water load. After joining the structures, a system is obtained that has high efficiency and the ability to form in various volumes and shapes. An extensive range of products allows you to choose the right option for playgrounds, adjoining areas and parking lots. The drainage tunnel is equipped with regular places for pipes and special plugs located on both sides of the structure. It should be noted that when used under parking lots, the products must be covered with soil, the layer of which is at least 50 cm. When used in pedestrian areas, the minimum layer is within 25 cm.
