1. How to connect double-walled pipes

The pipes produced by the company are in the form of head couplers and their connection is done from one side. For connection, the end of the tube (male) and the inside of the coupler (female) should be cleaned, and then the relevant washer should be placed right on the end of the tube, and then it should be lubricated by soap, water or other substance.

Using Tefur, insert the tube into the coupler, being careful not to spin the rubber gasket on the tube, as this will not seal it.

A) corrugate pipe trenches

According to the standards, the width of the trench should not be more than what is used for compaction and earthworks on both sides of the pipe. In fact, the width of the trench will depend on the embankment materials, compaction method and pipe diameter.

Typical width for pipes with a diameter of 250 to 600 mm is twice the diameter of the outlet, but pipes with a diameter of 700 to 900 mm are usually equal to the outside diameter plus 0.6 meters, and for pipes above 1000 mm and above, the width of the trench is equal to the outside diameter plus one meter. . Trench width can vary depending on the type of embankment material and compaction method.

Sometimes two or more corrugated pipes are placed next to each other, the distance between the pipes is changed according to the table below.


B) Infrastructure

Substructure is a part of the embankment complex that is built directly on the foundation and in the path of the path construction should be enough to create a strong support for the ladder and maintain the grade of the pipe, usually the minimum common depth of floor construction (_) .

C) Muscl building

The pollen range of the pipe in the embankment complex provides the highest resistance to open soil and traffic. The embankment material should be layered or phased and uniformly on both sides of the pipe and the material should be pushed under the pipe to fill the gaps. If compaction is required, this should be done so that the pipe path is changed. Do not and prevent the compaction device from being placed directly on the pipe. The embankment does not extend to the center line of the pipe to complete the muscle building area around the pipe


D) Primary embankment

The initial embankment distributes the loads within the pollen area of the pipe, which is at least 0.15 m from the crown of the pipe to the center line of the pipe.


D) The final embankment

The final embankment extends from the initial embankment layer to the ground surface. This embankment is not a direct support based on the pipe. But it plays an important role in the distribution on the pipe, in busy places, the height of the initial and final embankment should be at least 0.3 meters.
