During the past two decades, with development and innovation of new methods of production in the field of molding and manufacturing plastic parts, especially big and very big parts, replacing polyethylene manholes instead of concrete ones have been prevalent.
1. With regard to an earthquake-prone condition of Iran, this type of manhole due to its flexibility is consistent with small movements of the earth and as a result of small movements; it is not cracked and seamy.
2. Trench opens and closes easily in one day, and this means avoiding to waste time and reducing high cost.
3. Polyethylene is light and its installation and transportation takes place easily. Meanwhile, less equipment is applied for putting the manhole in a proper position.
4. Its perfectly smooth surfaces prevent the materials from sticking to the walls. This manhole is resistant to violent garbage caused by domestic and industrial discharges.
