The installation of metal rainwater tanksÂ module
, trench excavation, digging groove depth should comply with the requirements of groove foundation area should be rain water tanks with a total area of slightly larger than laying;
Groove foundation treatment: according to the processing of different soil types were different, but must ensure that the foundation of the structure of the solid reliability, must strengthen, leveling.In China need rainwater collection system of cement or lime treatment to strengthen the foundation stiffness and anti-seepage ability.Foundation after ramming flattening, and then put a layer of thickness is 100 mm above the sand bed.
Smooth, laying geotextile, the geotextile shakedown is located in the groove on the foundation of and around, so a rainwater collection system, should be laying geotextile first, and then add a layer of impervious membrane;
RKC waalwijk rain water tank laying and installation: use the avatar horizontal fittings connect namely the metal rainwater tanksÂ equality, try to avoid in the process of installation of laying continuous vertical connection, laid the first layer, the first step by step upwards again laid, the rain water tank between layer and layer with avatar longitudinal fittings connection;
Parcel impervious membrane (rainwater collection system) : the anti-seepage film tightly wrapped in boxes around, and sealed in accordance with manufacturers recommendations;
Penetration/tank and pipeline connection pool: use special powers to fittings, with DN160/315, DN400 and DN500 pipe connection;
In order to prevent the sediment into the permeability pools/reservoir blockage feed line road and reduce the storage capacity, general advice before the suction culvert installation avatar filter unit;
Parcels geotextile, and on the top of the permeability pools/reservoir protecting covered with a layer of soil;
In penetrating pool/fill in 100 mm between reservoir and groove wall coarse sand and cement, finally the backfill on the shop.
Note: before construction shall be carried out in accordance with the relevant drawings and operation manuals.
