Applications

Applications

The EZIpit® is a polypropylene inspection and maintenance structure (Maintenance Shaft, Maintenance Chamber or Maintenance Hole) designed for buried gravity sewer applications. It supplements our plastic pipeline systems and is used for inspecting and maintaining sewer network systems. It consists of a base, a single wall corrugated riser, a reducing cone for maintenance holes and a range of covers designed for trafficable and non-trafficable areas. The design allows safe access to the sewer from the surface.

Access Shafts, Chambers and Maintenance Holes are used (where practicable) at every:

  • Change of alignment
  • Junction
  • Change in the size of a sewer

In addition they are used at specified intervals for inspection and maintenance. National Sewer Standards and Codes specify requirements for the location and spacing of Inspection Shafts and Chambers.

Advantages

The benefits of polypropylene in gravity sewer or sewerage systems include high resistance to sulphuric acid erosion, low specific weight and high modulus, producing a stiff light weight structure and resistant to abrasion, resistance surface wear.

The overall benefits of the EZIpit® system include:

Features Benefits
Flexiblity The base includes adjustable pipe sockets which allow the pipe grade or angle to be adjusted up to 7.5o in any direction in the trench.
Long Service Life Polypropylene base and riser for chernical resistance in sewer environments.
Robust & Flexible Riser Flexible corrugated riser accommodates ground movement and dynamic traffic loads without cracking or breaking. The riser is easily cut on site for height adjustment.
In-ground Performance Fully resistant to external loads up to a depth of 6 metres and waterright up to 5 metres.
Ease of Installation Light-weight modular components for ease of handling in deep trenching.
Safety Performance Can be assembled and backfilled at the same time as the sewer pipe. reducing costs in plant, labour and the risks associated with open excavation.

FAQ

Frequently Asked Questions

How deep can you bury the EZIpit® ?

The EZIpit® can be buried to a maximum installation depth of 5m and a minimum depth of 1.2m to invert.

Why is the shaft corrugated?

The corrugated shaft provides further flexibility and as a result can deflect and absorb dynamic traffic loads without cracking.

Can the EZIpit® be installed in a roadway?

Yes. The EZIpit® is designed to resist loading and can be supplied with a Class D cover arrangement, which complies with AS 3996.

Will the EZIpit® resist flotation when buried in water charged ground?

Yes, the corrugated wall will key into the compacted embedment material resisting any up thrust. Tests in the field have been successfully conducted, confirming the unit doesn’t float.

Can you use SewerMAX® pipe with the EZIpit®?

Yes, but only in DN225. The DN225 SewerMAX® spigot x socket pipe adaptor allows connection to the base when using SewerMAX® pipe.

Can the EZIpit® be supplied with an internal or external drop structure?

Yes. The EZIpit® shaft can be supplied with a polypropylene spigot welded into the side of the shaft allowing connection to PVC DWV Sewer Pipe. The welded spigot ensures a watertight connection.

Is the EZIpit® frame and cover gas tight?

Yes, the frame and cover is gas and watertight and complies with AS 3996.

Why does the EZIpit® system have a cap and lid?

The cap and lid was designed to prevent personnel entry.

Can you install an access ladder in the shaft?

No, The EZIpit® is an inspection and maintenance chamber and not a manhole. Therefore it has been designed to prevent personnel entry into the confined space. The cap and shaft do allow inspection with CCTV and blockage clearance with water jets.

Do I need a crane to install the EZIpit®?

No, The EZipit® has been designed for ease of handling and installation.

Is the EZIpit® suitable for stormwater applications?

Yes, the EZIpit® is suitable for storm-water drainage applications provided the minimum cover is not less than 1.2m’s to invert.

Yes, The shaft is one continuous length with no joints eliminating any potential points for root intrusion.

The rubber ring joint connecting the shaft to the base is also resistant to root intrusion and complies with AS/NZS 1260 and AS/NZS 5065 with respect to joint performance.
