INSPECTION AND VALVE MANHOLES

Manholes are made of polypropylene desks by help of welding technology, with outside supports for settling under ground (backfilling by ground). Inspection and valve manholes serve for checking of water meters and next armatures on house connection of water supply (easy access).

Manholes included: - aluminium ladder, extension around lid H = 0,3 m, inter-connections 32 mm (watertight quick sealing device) - 2 pcs., plastic rectangular lid 600/600 mm.
1) A) Valve manholes – rectangular, self-supported (cannot be under road):

Dimensions (mm)
  • 900 x 1200 x 1200
  • 900 x 1200 x 1500
B) Valve manholes – rectangular, for concrete around

Dimensions (mm)
  • 900 x 1200 x 1200
  • 900 x 1200 x 1500
 

- Self-supported type A (for backfilling by ground) is designed and calculated for settling under green areas (you can walk on them). The bearing capacity of cover is max. 0,3 m of ground. It is forbidden to drive with car above valve manhole.

2) A) Valve manholes – cylindrical, self-supported (cannot be under road):

Dimensions (mm)
  • Ø 1000, H = 1000
  • Ø 1000, H = 1200
  • Ø 1200, H = 1200
B) Valve manholes – cylindrical, for concrete around

Dimensions (mm)
  • Ø 1000, H = 1000
  • Ø 1000, H = 1200
  • Ø 1200, H = 1200

- type for concrete around B (plastic manhole serves as lost boarding) is designed for settling under roads, or when there is high level of under ground water.

ADVANTAGES:
  • fast and easy assembly
  • very high quality of plastic material and welding works
  • 100 % water-tight of manhole
