For drainage of the site drainage or drainage systems are used. Independently it is possible to drain only surface layers of the soil on which the abundant amount of moisture from thawing of snow or precipitation accumulates. Only experts in the field as for optimum effect engineering and geodetic calculations are necessary can make the system of withdrawal of underground waters.
It is required to you
- - shovel;
- - crushed stone or gravel;
- - pipes;
- - well.
Instruction
1. For drainage of the site by means of drainage or drainage system it is necessary to make the exact plan in the period of abundant rains or thawing of snow. Draw the scheme according to which you will carry out drainage works. Note the most flooded places.
2. According to the plan dig through drainage ditches with bias towards well or ditch. Their depth needs to be done not less than 50 cm. Carry out bias so that the accumulated moisture, without being late, flew down in well or ditch.
3. Drainage ditches can be equipped with sewer pipes both to dig or leave open and to cement or pour out crushed stone. The most convenient the option with laying of pipes, but this quite expensive construction is considered. Open drains can grass and cope badly with the task, they should be cleaned constantly from garbage and grass, and during thawing of snow to remove the formed ice.
4. If you have decided to install drainage system with the equipped pipes, then establish sewer. Other types of pipes will not cope with problem of water drainage.
5. In certain cases, if the site very crude, then in dry weather it is possible to remove all fertile soil layer, to move away him aside. To pour out bottom crushed stone or gravel and again to fill up with fertile soil layer. Only after the performed work it is necessary to carry out drainage ditches and to equip in their way stated above, that is to leave open or to make closed, with laying of pipes. It is very effective method of drainage of the site, but very labor-consuming, he demands big material investments.
6. If your site crude because of close groundwater occurrance, then as it was already stated above, invite experts for exact calculation of deep drainage. Independently with this task to cope very difficult.
