TECHNICAL & INSTALLATION INFORMATION

1. Technical System of TechnodrainThe channel represents the technology of Technodrain from Asoplast, demonstrating decades of experience by their designers in the field of drainage. All solutions techniques and construction details were marked to provide an end –user product that is light, safe and easy to install. Technodrain wins the challenge compared to traditional systems, thanks to its versatility and affordability of installation, strength and durability of its structure. The HDPE (High Density Polyethylene) makes it light weight and immune to chemical attack.

2. Advantages over Traditional Systems • Light weight compared to size, cost of transport and installation. • Robust,unbreakabletobumpsandfalls. • Technodraincanbeusedinthefieldtemperaturefrom-60°Cto+100°Cwithout damage. • Chemicallyresistsawiderangeofacids,saltsandhydrocarbons.Technodraincan also be used in special environments such as chemical plants, workshops and service stations and is particularly suitable for roads with use of intensive salt anti-freeze,destructivetomosttraditionalsystems. • SurfaceresistancetomoldandmicroorganismsmeansTechnodraincanbeusedin all structures that require high hygiene such as flooring in kitchens, food processing industries, hospitals, etc. • Coefficientofpeakflows,thesurfaceareaoftheTechnodraindoesnotcreate barriers to water flow and minimizes the storage of aggregates. • Thesystemisveryversatileasthesamechannelcanbeinstalledwithdifferent grateoptionsfromClassAtoClassD. • Preformeddischargeoutletslocatedonthebottomandsidepanelsofthechannel, allow quick and simple connection to storm water discharge pipes. • Thepossibilityofmountinggrooveswiththefixedgrate,makesitextremelyfastto install.

ADVICE FOR THE INSTALLATION OF TECHNODRAIN DRAINAGE SYSTEM

Step1.LoadClassRequestThe first step in designing a drainage system is the choice of grate.These choices are based on the characteristics of load resistance the channel grate must endure, the architectural finish preferred, and the surface water capture characteristics in relation to thesizeofthegrate.TheloadclassesforthegrateoptionsarespecifiedinAS:3996.

The Specifier should also pay attention to potential future changes of use of an area which may be subject to heavy or construction loads (e.g.: Semi Trailers or earthmoving equipment) which may necessitate selecting grates suitable for higher load class rating.

ClassLoadingsasperAS:3996arelistedbelow

Class Peferred Usage of drainage systemA 15kN Pedestrian areas and cycle paths

B80kN Areas including footways, accessible to light vehicles.

C150kN Mallsandareasopentoslowandmovingcommercialvehicles.D210kN Carriagewaysofroadsandareasopentocommercialvehicles.E400kN General docks, carriageway roads, aircraft pavements.F600kN Docks and aircraft pavements subject to high wheel loads.

G900kN Docks and aircraft pavements subject to very high wheel loads.

Step 2. Design of drainage systemThe collection and drainage system should be sized according to the rainfall and meteorological characteristics of the site concerned, size, shape and slope of the catchment area, type of surface used (asphalt, concrete, paving, lawn, etc.), and the properties of the runoff liquid being captured.

Attention should also be paid to access roads or roofs that may concentrate water into the catchment area being considered as the total flow to disposal will be the summation of all these components.

Step 3. Laying

The Technodrain channel and grate system requires a base of concrete thick enough to spreadtheverticalandhorizontalthrustloadsinaccordancewiththeClassratingofthegrate selected.

A. Preparing the ground for installation: The excavation for the installation of the drainage system Technodrain must be dimensioned taking into account the channel selected and thickness of concrete required fortheabutmentandthesubstrateasgivenintable1.Inadditiontothesethicknesses(Rand S) the excavation should allow for the possible passage of pipes to the final drain connection. The natural ground the drain is being laid in must have a bearing capacity sufficienttosupporttheloadclassesselected.Itmaybenecessarytoincreasethebearing capacity by tamping down the foundation or providing some form of ground or soil reinforcement. In particularly soft sub grades may be necessary to make the concrete foundation wider to provide a greater support area.

Figure 1:

B.ConcretebaseThe bedding must be prepared to provide for a concrete base thickness of S. The oncrete to be used for the base of Technodrain must have flow properties conducive to the filling of all cavities formed by the ribs external reinforcement channel for the same reason the size of aggregatesinconcretecontentshouldnotexceedthediameterof15-18mm.

The minimum strength class of concrete for the foundation and abutment must be between 25 to 30MPaforgrateloadclasses(A10,B80,D210)and38to40MPafortheheavierloadclasses(E400,F600,G900).ThereareanumberofpremixedmortarsinthemarketthatmaybeusedsuchasMapegroutSVSikagrout312EmacoUltraRapidorsimilar.Forinstallationsincoldtemperatures,Emaco Fast or similar can be used.

C.InstallationofchannelFor the proper installation of the Technodrain channel, begin the installation from the point of discharge (well), connecting the outlet to the stormwater system.

Pro200HChannel&Grate:Ensure that the galvanized clamps are embedded into the ubstrate or foundation of the concrete envelope around the channel.

MagnumCity300Channel&Grate:For better anchorage of the channel, the insertion of steel rods of 8 to 12mm in diameter into the connections located on the outside of the channel and embedded into the substrate or foundation of the concrete envelope around the channel.
