IDS MK II
IDSMKII access chamber system is manufactured from polypropylene 20% talc filled. The material is 100% recycled and also 100% recyclable. The material is injection moulded into a ribbed twinwall construction for superior strength while maintaining a profile which allows minimal excavation to take place. The access chamber system is made up of a duct entry section where the duct is inserted into a premoulded entry point which is freed up by the removal of a blanking cap. Where the entry points are not required then the blanking cap is left in situ. The blanking caps are ribbed and unlike other systems on the market the blanking caps are manufactured from the same material as the chamber ensuring no loss of strength at these points. IDSMKII is manufactured in a range of sizes up to 600mm2. If larger sized access chambers are required then please see our section on large size structural chambers. Product CodesThe duct entry section is specified as a 3030DE for 300mm2 and a 6060DE for 600mm2. The first 4 figures denote the size of the chamber and the DE signifies duct entry section. Similarly the raising pieces operate on the same principle in that a 6060RP denotes a 600mm2 raising piece. Installation InstructionsExcavationsExcavate the installation area to the depth of chamber plus 40mm, plus depth of base. Base of excavated area to be well compacted granular material or 100mm concrete slab. Allow enough room around the chamber for a minimum surround of 100mm. If the chamber is situated in a footpath or an area where C250 loadings are required then 10mm clean stone or as dug material can be used to surround the chamber. The IDS Mark II access chamber will achieve a C250 loading-freestanding. It is however the responsibility of the contractor to ensure that the chamber is installed in such a manner that tortional forces exerted on the cover and frame will not have an affect on the chamber in respect of any lateral movement. Installation GuidelinesInstall chamber centrally within excavation. Remove duct ports as required and fit ducting into chamber. Ensure the ducting has a minimum 40mm key within the chamber. When the chamber is located correctly, backfill the void around the chamber with surround as described above. Ensure backfilling is done around the perimeter of the chamber in equal measures on all sides to prevent movement or distortion. Fill to the height of the top lip of the chamber and concrete the frame in at the appropriate height/angle. It is strongly recommended that the frame is in-situ when installation of the chambers takes place. Raising PiecesRaising pieces are used above the duct entry base section to achieve the required height of the duct chamber. The height should be defined by the number of ducts in the chamber and the amount of safe working space within the chamber for electrical work to take place. Depth of CoverEach section is a nominal 150mm deep, therefore a chamber requiring a minimum 450mm depth of cover would consist of 1 duct entry section plus 3 no raising pieces. 600mm depth of cover would consist of 1 product entry section plus 4 no raising pieces. 750mm depth of cover would consist of 1 duct entry section plus 5 no raising pieces. IDSMKII Access Chamber System Specification ClauseThe access chambers shall be made of recyclable polypropylene consisting of a twinwall ribbed construction which will comply with the loadings of C250 when installed and backfilled with 10mm clean compacted stone surround. There shall be no drilling or cutting required for insertion of 110mm ducting. The blanking caps shall be made of the same material as the chamber to ensure uniform rigidity and strength. The access chamber shall suffer no deformation due to climatic changes between temperatures of -40°c to +100°c. |
