Specific internal wiring works of sewerage

Mounting the horizontal collectors

Installation is apparently horizontal collectors and / or buried.

In buildings that are technically underground sewerage pipes are mounted on the console and apparently metal bracelets.

If buildings are not technically underground, but normal land, installation will run horizontal drain fitting collectors buried in the ground floor under the floor.

If the land is that is sensitive to macroscopic softening when installing horizontal drain collectors under floor ground floor will be executed in concrete channels for interventions and controls.

Issues that must necessarily resolved during horizontal piping installation:

1. compliance specified in the project drain slope

2.. Correspondence between the close scrutiny share of output pipe of the building and outdoor sanitation

Horizontal collectors are placed at the bottom of the sewerage and sewage pipes are thus the first domestic installation of the mounts, taking into account any building that runs from the bottom up.

After collecting duct will be installed and the final column connections to sanitary, so installation will be done in reverse flow.

The horizontal collector in each column will be set right many a branch which connects the drain and collector vertical columns

The collectors are mounted bends, parts cleaning and elbows.

Branches connected to the collector columns.

Connection column will run with branches with angle 45 °, thus eliminating the danger of clogging is because once installed can not walk the ramifications.

Branches are allowed only in exceptional cases with the angle of 70 ° (67 ° 30 ‘  if the material is PP.)

In this case, the main pipe after each branch is mounted a tube placed in cleaning manholes.

Because branches clogging double favors they will not use the horizontal collector.

Parts cleaning is mounted to steering at branch points with the possibility of clogging and straight paths at distances between 6 and 15 m.

Elbows and reducers are mounted to the respective section lines change direction.

Collector pipe bends should be as large, will not provide change of direction with angles greater than 45 °.

Mounting columns sewerage

Columns collector is connected to the branch pipe 45 ° or T mounted on the pipe collectors.

Provide parts cleaning is required every two levels but the first and top floor.

For plaster or hidden columns are buried under leaves to cover the possibility of visiting cleaning tubes.

Cleaning parts mounted on columns placed 800 mm above finished floor to floor in question, that way if desfundarii column, the water drain tube does not flood the floor cleaning and can manage the sanitary branch of the column.                                                           If collecting pipes mounted under the ceiling basement, ground floor cleaning tube serves for cleaning the pipe collectors.

Optimal position fixing are fastened bracelet that is as plug columns, where due to the shape of the tube, pipe bracelet securely.

Installation of sanitary drain connections

Sanitary drain connections of the columns can be mounted as follows:

-Along the wall on which are located sanitary apparently buried or disguised as constructive system or the comfort allows.                                                                                                                      -Buried in the floor thickness, solution used for toilets          

Sections of sewer will be buried under the floor and pictures on a bed of sand filling, moist and well compacted, with respect for the position and slopes of the project.

-Sub floor that is mounted sanitary apparently masked by a beam or false.

Crossing concrete floors will be used provided the project goals and crossing pieces.
