Ecol-Unicon specialises in producing high-quality modular precast reinforced concrete chambers used in storm water drainage, sanitary and industrial sewage systems. Many years of experience in different construction industry branches and advanced technology used have enabled designing functional and reliable production solutions. High-class materials and constant parameter monitoring at all production facilities guarantee high quality of product, resistance to any kind of damage and ability to be used in difficult soil and water environment. All products have all necessary certificates and comply with rigorous construction norms. The durability and dead load of concrete are the advantages of using concrete products, which guarantee long life of the whole construction. Ecol-Unicon offers a wide range of concrete chambers, which basic reference is their internal diameter – ID.

DZB CHAMBERS CHARACTERISTS

  • Modular design - > customised shape configuration and customised dimensions suited to Client's needs
  • Can be located in overrun areas (load class complying with PN-85/S10030 and DIN 1072) or green areas
  • Tight connections – seals and steel swages
  • Easy to clean
  • Resistant to live loads
Heavy weight – less sensitive to groundwater buoyancy and changing its location -> does not require additional foundation slabs  

CONSTRUCTION

Every DZB chamber consists of semi-circular or EU-MD flat chamber base closing elements, EU-MN superstructure elements, EU-MP cover and EU-U extension element. The chambers come in different heights, widths and lengths and are made of different materials with parameters depending on customer requirements. They can come with access steps or ladders made from stainless steel, access chimneys, inside baffles, sumps etc. The chambers come in different heights, widths and lengths and are made of different materials with parameters depending on customer requirements.

TYPES OF CHAMBERS

Modular precast reinforced concrete chambers are products with oval, circular and cudoidal cross-section ( ID = 4600, 5000, 5600, 6000, 8000 mm) made from reinforced concrete (according to PN-EN 206-1). Depending on their construction, all chambers produced by Ecol-Unicon can be divided into vertical (Fig. 1) and longitudinal (Fig. 2). Przykład pionowego zbiornika DZB Ecol-Unicon

VERTICAL CHAMBERS

Vertical chambers are made of two EU-MD base closing elements, EU-MN top element depending on chamber height and EU-MP slab (Fig. 7).

Advantages of vertical chambers:
  • foundation – up to 10 m below ground level;
  • chamber height – up to 10 m;
  • chambers can be installed above ground level, below ground level or partially in the ground.
 

LONGITUDINAL CHAMBERS

Longitudinal chambers are made of EU-MD oval or flat closing elements, EU-MP top elements, EU-MU extension elements and EU-MP slab (Fig. 8). Using extension elements allows constructing chambers of different length, depending on Customer's needs.   Elementy zbiornika DZB 2

Advantages of DZB longitudinal chambers: – great internal height – up to 6.0 m – big chamber length – up to 100 m – big storage capacity – up to 4000 m3 – possibility to assemble chambers parallelly - wall to wall.           x                            
DZB chambers are used in water sewage systems as:
  • chambers functioning as pre-treatment installations (settling tanks, separators, pre-treatment chambers and pumping stations) [for more information see chapter: Retention and Reuse]
  • dry chambers (housing of pumping stations, hydrophore plants, water meter chambers)
  • speading basins
  • potable water reservoirs
  • storm water reservoirs
  • septic tanks
  • fire water tanks
  • gate valve chamber
  • wastewater separation chambers
  • liquid manure tanks
