In the field of water networks, corbelling refers to a construction technique in which a pipe is installed protruding from the bare surface of a wall or existing structure. This method is particularly useful for wastewater conveyance networks, such as the one recently installed in Martignat (01).
Advantages of corbelling for force mains :
Corbelling offers several advantages for wastewater conveyance systems:
High-density polyethylene PE100 is the ideal material for corbelled pipes, especially in its pre-channelled version. Here's why:
PE100 offers improved resistance to chlorinated disinfectants, even at high temperatures. This feature is crucial for wastewater networks, where operating conditions can be extreme.
This material offers excellent resistance to impact and slow cracking, ensuring longer pipe life.
PE100 pipes can be laid without a sand bed, which considerably simplifies installation, especially in corbelled configurations.
Available in bars of various lengths (up to 12 meters), PE100 is perfectly suited to the specific constraints of corbelling projects.
The pre-sleeved version facilitates connections, reducing installation time and the risk of leaks.
PE100 offers total resistance to chemical aggression, a major advantage for wastewater networks.
The use of PE100 for corbelled pipes represents an advanced technical solution for wastewater force mains. Its unique combination of strength, durability and ease of installation makes it a wise choice for modern hydraulic infrastructure projects, such as the one at Martignat. This innovative approach not only optimizes wastewater management, but also reduces the environmental impact of construction sites, while ensuring a longer service life for installations.
