Key Properties and Benefits
Astral Drain Hulk manhole chambers and inspection chambers are designed with advanced features that set them apart from conventional drainage systems. Here are some of the key properties and benefits:
The availability of ready-made inspection chambers, long lengths of lighter-weight pipes, and various components make the installation of the Drain Hulk system fast and convenient. This flexibility is crucial in reducing installation time and labour costs. This makes it an efficient solution for large-scale projects.
Astral Drain Hulk ensures trouble-free performance with joints that prevent blockages and leakage. This feature of the manhole chamber is vital for maintaining high standards of hygiene, especially in environments where sanitation is of utmost importance, such as hospitals and residential complexes.
- Perfect Hydraulic Properties
The chambers are designed with an in-built slope that enhances the hydraulic capabilities of the system. This design ensures efficient water flow, which reduces the risk of water stagnation and associated problems like odour and sediment buildup.
Thanks to the simple joining technique, the trench width required for installation can be kept to a minimum. Additionally, the smoother bore of the pipes allows for high flow rates at relatively flatter gradients, further reducing excavation and installation costs.
The connection between the pipe, riser, or shaft and the chamber base is watertight, which ensures that there are no leaks. The design of the pipe joints with a click ring and sealing ring makes the system completely leak-proof, which is essential in preventing groundwater contamination.
The system’s optimum functional qualities, good hydraulic properties, and smooth surface finish reduce the need for regular maintenance, such as jetting. This feature not only lowers operational costs but also ensures that the system remains functional and reliable for an extended period.
- Great Strength & Durability
Astral Drain Hulk is sufficiently durable to meet site loading requirements. This makes it suitable for both on-road and off-road installations. The system’s strength ensures that it can withstand heavy loads and challenging environmental conditions without compromising its integrity.
- Longer Life and Overall Economy
Due to superior chemical resistance and durability, Astral Drain Hulk offers a long service life and trouble-free operation. This longevity, combined with the system’s efficiency and low maintenance requirements, makes it a cost-effective choice for long-term drainage solutions.
Installation Guidelines for Astral Inspection Chambers
Proper installation of inspection chambers is important to ensure the system’s effectiveness and longevity. Here is a step-by-step guide to installing Astral inspection chambers:
Begin by excavating the trench according to the specified dimensions. The trench should be 300 mm wider on all sides of the chamber and 150 mm deeper than the chamber invert depth. Compact the excavated base layer to 95% and lay a PCC (Plain Cement Concrete) layer of 150 mm height.
- Installing the Chamber Base
Place the inspection chamber base on the PCC layer and fill the gaps below the base with PCC. Ensure that the chamber is horizontally aligned by checking the levelling.
Drill the hole for the inlet pipe at the pre-marked positions using an Astral cup saw. Insert the inlet rubber seal and push the plain (spigot) end of the PVC pipe into the seal for a watertight connection. No glue or silicon is needed, making the process straightforward and efficient.
The outlet connection is a spigot type. Slip the socket end of the PVC ring fit pipe onto the outlet connection and apply lubricant for smooth insertion. If necessary, cut off any unnecessary spigot at a right angle with a saw to ensure a proper fit.
- Assembly, Backfilling & Compaction
Ensure the chamber is level and aligned with the connecting pipes. Backfill around the chamber in layers of 300 mm, compacting each layer to 95% with a mechanical vibrating stamper. For greater stability, use gravel or sand for backfilling, as these materials have high permeability and absorb lateral thrust.
- Height Adjustment and Cover Installation
Adjust the chamber height on-site by cutting the upper edge of the chamber if necessary. Install the PE cover for non-traffic areas or a concrete load-bearing ring for traffic areas. The load should be absorbed by the frame and cover, not the chamber itself, to prevent damage.
Installation Guidelines for Astral Manhole Chambers
Installation of manhole chambers is an important process that must be done with precision to ensure the system’s long-term functionality. Here’s an overview of the installation procedure for Astral manhole chambers:
Excavate a trench 300 mm wider on all sides of the manhole chamber and 150 mm deeper than the manhole invert depth. Compact the excavated base layer to 95% and lay a 150 mm PCC layer on it. Place the manhole chamber on the PCC and fill the gaps below the base with PCC, ensuring horizontal alignment.
To connect the inlet pipe, drill the appropriate diameter hole at the pre-marked positions, insert the inlet rubber seal, and push the plain end of the PVC pipe into the seal for a watertight connection. Astral seals allow for 5° movement in all directions, accommodating site constraints.
The outlet connection is a spigot type. Slip the socket end of the PVC ringfit pipe onto the outlet connection and apply lubricant for smooth insertion. If required, trim the spigot for a proper fit.
- Assembly, Backfilling & Compaction
Check the levelling and alignment of the manhole chamber and connecting pipes. Backfill around the manhole chamber in 300 mm layers, compacting each layer to 95%. For increased load-bearing capacity, use gravel or sand as backfill material, as these materials absorb lateral thrust.
- Height Adjustment and Cover Installation
Adjust the height of the manhole chamber by cutting the upper edge if necessary. For traffic areas, install a concrete load-bearing ring around the neck of the chamber, avoiding direct contact with PCC and RCC. The frame and cover should absorb the traffic load, not the manhole chamber itself, to ensure durability.
