DN1200 Easi-Base Dimensions P27 Channel Depth (mm) Easi-Base Height (mm) Invert to Base Top (mm) 150 520 370 150mm 1200mm 200 570 420 225 620 470 250 620 470 300 670 520 Unit weights vary between 1.5 tonnes and 2.5 tonnes depending on channel diameters and channel configuration. 520mm - 670mm 5° IN 160mm Invert Height 10% 1% 150mm 5° OUT Features • The DN1200 Easi-Base is made to an internal diameter of 1200mm with tongue and groove joint profile to match standard DN1200 manhole chamber rings. • Wall thickness is 150mm. • The base has a 150mm floor thickness with the outlet invert at exactly 150mm from ground level. • A 1% fall exists across the channel toward the outlet (1:100). • A gradient of 1:10 is present at the benching with the run-off toward the channel. • The height of the DN1200 Easi-Base unit varies in accordance with the diameter of the main channel running through the unit. (Please refer to the table above for approximate heights). • The DN1200 Easi-Base unit has 5° flexibility in the seal at each pipe connection point, this can be achieved both horizontally and vertically. (This is best illustrated in the diagram below). • Additional connections can be made to a DN1200 Easi-Base unit once installed. This can be achieved either by coring into the existing unit and fitting a connection in the traditional manner; alternatively by the use of a backdrop into the manhole. • Easi-Base is a Kitemark product - manufactured and tested to BSEN 1917. • Easi-Base meets with WRc Approval. • Easi- Base is accepted for use by all major UK water companies. Note: A copy of the WRc Approval and copies of water company acceptance letters are available through our website or upon request. PT/274/0808 Easi-Base is a kitemark product, manufactured and tested to BSEN1917:2002 27 www.fpmccann.co.uk precast@fpmccann.co.uk
DN 1500 & DN 1800 Precast Concrete Easi-Base DN1500 - DN1800 Easi-Base (GRP & Unlined) P28 The Easi-Base range extends to include the larger diameter DN 1500 and DN 1800 concrete manhole bases. These bases will accommodate concrete, clay, twin wall and uPVC pipes from DN 300 to DN 900mm. Connection to the base is made on site by applying epoxy resin to a conventional socket / spigot butt before insertion into the opening of the precast manhole. Bases are traditionally constructed manually in-situ using ready mix concrete which is troweled to form the base and benching. This practice is labour intensive and requires optimum site conditions to achieve a quality result. The Easi-Base precast alternative removes many of the variable factors in the manual process. Benching and channels are generally pre-formed with concrete, but glass reinforced plastic (GRP) linings are available for special applications on request. The DN 1500 and DN 1800 units are WRc approved and offer the same construction benefits as the DN 1200 Easi-Base. PT/280/0109 (GRP) PT/279/0109 (Concrete) 28 www.fpmccann.co.uk precast@fpmccann.co.uk
