Repair of storm water drain

Maintenance of drainage in the cold season

Maintenance, as well as maintenance of the system, include regular maintenance, which aims to monitor the system and diagnose its stability after heavy rains and floods, as well as thorough cleaning, which involves removing contaminants from drainage wells and repairing storm sewage inif necessary.

When there is soil icing, scarce runoff and actual lack of groundwater in winter, there is practically no water in the drainage canalization. If you adhere to some recommendations, you can avoid system conservation:

• Laying drainage pipes to a depth that is below the freezing depth of
• . If the pipes work in gravity, this can prevent them from breaking in the cold season.
• You need to equip the rubble around the drainage. This will protect the pipelines from freezing, and gravel and air will work as a thermal insulation.

In the event of cold weather from the uninsulated drainage well, the pump set must be removed. Back to install it is necessary before the work of drainage canalization, that is, in March or April.

Maintenance of the drainage system of the sewerage system

During the use of storm sewerage, pipes and manholes are fitted with manholes and plugs to prevent debris and dirt from getting into the system.

1. Regular maintenance. The work of the drainage system assumes the accumulation of mud, mud and debris at the bottom of the wells, which is carried into the pipelines. If you control the level of pollution of the well, you can avoid clogging up the entire sewage system. If the sediment level is sufficiently large, it is necessary to clean the well. It is produced with the help of a drain pump and a hose supplying clean water. Pollution forms an emulsion with water, which is pumped out by the pump.
2. Capital cleaning and repair of storm sewage. Every 10-15 years, it is necessary to carry out system diagnostics and thorough flushing of pipelines to remove sediments and sediments.

In order for the cleaning to be optimally organized, it is necessary to construct drainage wells first and at the end of each pipeline, as well as at every second turn.

Flushing has both direct and reverse character: from the end of the pipe to the beginning, and then vice versa. Drainage is cleaned by water, supplied under pressure, only after cleaning the drainage well.

Proper use of drainage and timely organization of maintenance and repair work extends the life of pipelines to 50 years. Then, the polymeric materials that make up the pipes wear out, but the system's suitability is still about 20 years.

Repair of storm catchers

The storm sewer repair begins after its diagnostics and determination of the system's operability. If the ability to pass precipitation deteriorates, determine which parts of the system have become unusable. Then it is necessary to check the sewerage and after that it can be put into operation, but it should be remembered that in order to avoid flooding of the site, repair work should be carried out in the shortest possible time.

1. The peculiarity of the rain shower is that it mainly consists of metal pipes, which means that it can be corroded.
2. Repair involves the replacement of metal pipes with a diameter of 0.1 m on polymeric pipes of the same diameter, except for the outlet of the pipe, located after the hydraulic shutter, which must be steel. This extends the life of the system to 50 years
3. For external drainage pipes made of steel, coated with zinc, are used. Since air is circulating in it and it does not come into contact with the ground, its useful life is sufficiently long.
4. To prevent a drainage rupture in winter, it is necessary to equip the

Heating of the storm shower

The storm sewer can be heated by means of an electric cable that is laid on the inner walls of the pipes or wrapped around the outside, and additionally insulated.

The most effective is the use for such purposes of a self-regulating electric cable, which contributes to energy savings due to automatic reduction of the degree of heating depending on the ambient temperature. Its use will make the storm system defrosting quick and convenient.

It should be remembered that the timely care of drainage and its cleaning, as well as the repair of storm sewage, will allow to extend the life of the systems on site, as well as to reduce material costs arising from unexpected breakages that appear if you do not pay proper attention to these things.
