Collection shaft 3x110/400pr/110 Prakto PIPELIFE MANHOLE

The professional left collection shaft of the world leader PIPELIFE from the specialized PRAKTO series (with a base diameter of ⌀400 mm) is a high-tech plastic bottom designed for the construction of modern inspection sewer systems. This element plays a critical role in external underground water supply networks, providing a reliable point for collecting wastewater from various branches of the installation, easy access for subsequent technical inspection and smooth change of direction of gravity pipelines. The model has a factory-configured internal chute (kineta) with three inlets and one main outlet with a diameter of 110 mm, optimized as a left collection configuration (RML) for efficient hydraulics without sediment retention.

The base of the manhole is made by precision injection molding of a high-strength polymer alloy of polypropylene (PP) and unplasticized polyvinyl chloride (PVC-U). This modern structure gives the manhole exceptional surface stiffness, elasticity and complete immunity against corrosion and the chemical influence of domestic, industrial or aggressive groundwater in a wide temperature range. The product is manufactured in full compliance with the strict requirements of European standards EN 476 and EN 13598, guaranteeing a long service life of over 50 years. Factory-fitted joints with rubber seals provide water tightness up to 0.5 atmospheres, and the upper body diameter of 400 mm offers full compatibility with standard corrugated manhole pipes, as well as plastic, cast iron or telescopic covers for any load class.

Purpose:

• For the construction of branches, collection points and inspection nodes in external gravity sewers
• For the removal and inspection of domestic waste fluids, surface rainwater and industrial flows
• For installation in yard, site, street and industrial sewage networks before discharge into the main collector
• To provide access for cleaning, diagnostic and preventive equipment (CCTV cameras) along the route

Main advantages:

• Maximum hydraulic efficiency thanks to perfectly cast internal chute to prevent sediment build-up
• Guaranteed service life of half a century without the need for expensive repairs and frequent system unblocking
• One hundred percent safety and protection against leakage during the soil settlement phase through the certified water tightness of 0.5 atm.
• Extremely easy transportation, positioning in the trench and quick fitting installation thanks to the net weight of only 7 kg
• Complete finishing flexibility through compatibility with PIPELIFE plastic, cast iron and adjustable telescopic covers
