Installation of storm sewage system and its installation

Design and calculation of stormwater according to SNIP

Project home equipment surface drainage system is performed according to reference standards and regulations for storm water drains SNIP 2.04.01-85.This takes into account many factors such as the location of the geological features of the area and intensity of rainfall in the area.Moreover, data on precipitation, are taken from the SNIP 2.04.03-85.Given these figures, you can calculate the maximum flow vodoottoka this design:

V = q20 x S x D

• q20 - intensity rainfall;
• S - area of ​​the roof, ha;
• D - coefficient determining the moisture absorption material surface (according to the handbook).

As can be seen from the geographical location of the house does not affect the final result, but also the material used.

next step will be preparation of Hydroproject, which takes into account all the main factors that determine the effectiveness of the stormwater:

• climatic features;
• geological features of the site location;
• soil type;
• diameters of pipe used;

With all of these, as well as other secondary parameters are the most optimal design storm sewer.

device stormwater: the basic elements and operation

This type of drainage systems is a system composed of various elements:

• gullies - a rectangular container made of polypropylene, are connected to the sewer system;
• trays are installed in front of the house door, and just as dozhnepriemniki collect water from the roof;
• trash box with a lid, which is designed to delay the various debris;
• Linear drainage (trays, gutters) drains water from a large area.Top covered with bars to prevent falling into the waste system.The width of the gutter depends on its capacity.
• Drainage PVC pipe with a diameter of 110 mm.Used as corrugated pipes, which due to its flexibility, forming different angles and curves.
• Manholes.

The principle of stormwater: plums from the roof gutter system to transport water inlets, which collects it and then piped takes her in a special reservoir or wells.This type is called livnevki closed.

addition to different locations on the site are set trays with bars, in which precipitation drains from the territory.Passing through peskoulavlivateli that trap debris, the water falls into the same wells.This is how an open sewer system.

And then derived from wells drains out of the territory.

installation stormwater

mounting structure directly related to the house, begins with the installation of drainpipes and gutters that collect water from the roof.All components are fixed with clamps to the walls.

After that make installation of street inlets.They are fixed with a special bitumen mastic, and the joints are waterproofed.Draining is carried out in the same reservoir or drain Tray ODD open.

ground part of sewage is set as follows:

• Under certain slant digging ditches and wells.Their depth should be below the level of freezing of the earth at the lowest possible temperatures for the region;
• bottom of the trench is filled with sand or fine gravel and well compacted;It is placed
• pipeline;
• Mounted gullies and peskoulavlivateli;
• All the elements are joined together in a single system;
• install the grille, and all that is filled with soil.

use of quality materials and properly executed installation will provide uninterrupted operation stormwater decades.
