Walter Zink, Nürtingen .*....* *..* : ..**..* Recycling-Substrat für extensive Dachbegrünungen Beschreibung:Walter Zink, Nürtingen .*....* *..* : ..**..* Recycled substrate for extensive green roofs Description:

Die Erfindung betrifft ein mittels Druckluft förderbares Substrat auf der Basis von mineralischen Recycling-Leichtbaustoffen - angereichert durch speziell ausgesiebte organische Bestandteile welches vorwiegend für extensive Dachbegrünungen eingesetzt wird.The invention relates to a substrate that can be conveyed using compressed air based on mineral recycled lightweight building materials - enriched by specially screened organic components, which is mainly used for extensive green roofs.

Substrate für extensive Dachbegrünungen bestehen heute größtenteils aus in der Natur abgebauten Schüttstoffen oder Schüttstoffgemischen, wie Lava, Bims, etc. oder aus energieaufwendig hergestellten Granulaten, wie beispielsweise Blähton- oder Blähschiefer. Diese Stoffe werden vor dem Einsatz entsprechend gebrochen und ausgesiebt.Today, substrates for extensive green roofs consist largely of bulk materials or bulk material mixtures mined in nature, such as lava, pumice, etc. or of granulates produced using high energy consumption, such as expanded clay or expanded slate. These materials are broken down and sieved accordingly before use.

In diese rein mineralischen Schüttstoffe, die mittels Druckluft und Schlauch- bzw. Rohrleitungen aus Silofahrzeugen auf Dächer gefördert werden können, werden entweder Ballenpflanzen eingesetzt oder Sproßteile, die im Laufe der Zeit Wurzeln bilden, bzw. Saatgut aufgebracht. Das Wachstum der Pflanzen wird sichergestellt durch entsprechende Düngung bzw. durch Abstreuen mit humosen Stoffen. Either balled plants or shoots that form roots over time or seeds are placed in these purely mineral bulk materials, which can be transported from silo vehicles to roofs using compressed air and hoses or pipes. The growth of the plants is ensured by appropriate fertilization or by sprinkling with humus-rich substances.

Wird Humus in gewohnter Form sofort dem mineralischen Granulat beigemischt, bereitet die Substrat-Förderung mittels Druckluft erhebliche Probleme, da es sehr häufig zum Verschluß der Rohrbzw. Schlauchleitungen infolge von Klumpenbildung kommt. Das Aufbringen einer separaten humosen Mulchlage ist wiederum ein Kostenfaktor bei der Anlage einer Dachbegrünung, genauso wie die regelmäßige Düngung, die zu höheren Unterhaltungskosten führt.If humus is immediately mixed into the mineral granulate in its usual form, the substrate conveyance using compressed air causes considerable problems, as the pipes or hoses often become blocked due to the formation of clumps. Applying a separate humus-rich mulch layer is in turn a cost factor when installing a green roof, as is regular fertilization, which leads to higher maintenance costs.

Die Neuerung betrifft nun ein Substrat, welches den Vorteil der Förderbarkeit mittels Druckluft vereinigt mit günstigen Wachstumsbedingungen für die Pflanzen. Es wird auf der Basis speziell aufbereiteter Recycling-Leichtbaustoffe (1), wie Tonziegel- und Bimssteinbruch hergestellt, denen zur Einhaltung der erforderlichen chemischen und physikalischen Parameter nach Bedarf geringe Mengen mineralischer Zuschlagstoffe beigefügt werden (2). Diese Zuschlagstoffe können regional unterschiedlich sein (Schlacken, Tuff,...). Zur biologischen Anregung wird dem Substrat ferner ein bestimmter Anteil kompostierter Rinden- und Holzstückchen (3) zugegeben. Diese sind so ausgesiebt, daß die Förderbarkeit mittels Druckluft gewährleistet bleibt. Über die Größe der kompostierten Holz- und Rindenstückchen wird im wesentlichen die Dauer des Zersetzungsprozesses festgelegt. Dadurch daß im vorliegenden Fall relativ große Partikel zugegeben werden, wird eine langhaltende Nährstoffabgabe erzielt.The innovation now concerns a substrate that combines the advantage of being able to be pumped using compressed air with favorable growth conditions for plants. It is made from specially prepared recycled lightweight building materials (1), such as clay bricks and pumice, to which small amounts of mineral additives are added as required to comply with the required chemical and physical parameters (2). These additives can vary from region to region (slag, tuff, etc.). A certain proportion of composted bark and wood pieces (3) are also added to the substrate to stimulate the biological process. These are sieved in such a way that they can still be pumped using compressed air. The size of the composted wood and bark pieces essentially determines the duration of the decomposition process. By adding relatively large particles in this case, a long-lasting release of nutrients is achieved.

Die Kornuntergrenze der mineralischen Stoffe liegt bei 2-6 mm, die Kornobergrenze bei 12 - 16 mm. Der Anteil der mineralischen Bestandteile an der Gesamtmischung beträgt etwa 70 bis 90 Vol.-%, hiervon der überwiegende Teil aus dem Baustoff-Recycling. Die organischen Bestandteile weisen eine Kornuntergrenze von 8 - 12 mm und eine Kornobergrenze von 20 - 28 mm auf.The lower grain size limit of the mineral substances is 2-6 mm, the upper grain size limit is 12 - 16 mm. The proportion of mineral components in the total mixture is around 70 to 90 vol.%, the majority of which comes from recycled building materials. The organic components have a lower grain size limit of 8 - 12 mm and an upper grain size limit of 20 - 28 mm.

Der Vorteil der Erfindung liegt darin, daß durch die Verwendung von Recyclingmaterialien natürliche Ressourcen geschont und beträchtliche Mengen an Energie eingespart werden. Die rationelle Aufbringtechnik bleibt aufgrund der speziellen Sieblinie und Stoffzusammensetzung gewahrt; der Zuschlag organischer Stoffe fördert das Anwachsen und die langfristige Entwicklung der Pflanzen. Die organischen Bestandteile bewirken eine höhere Adsorptionskapazität als sie rein mineralische Schüttstoffgemische besitzen; dies verbessert die Nährstoffspeicherung und macht zusätzliche Düngung überflüssig. Ebenso wird die Wasserhaltung verbessert.The advantage of the invention is that the use of recycled materials conserves natural resources and saves considerable amounts of energy. The efficient application technique is maintained due to the special grading curve and material composition; the addition of organic materials promotes the growth and long-term development of the plants. The organic components have a higher adsorption capacity than purely mineral bulk material mixtures; this improves nutrient storage and makes additional fertilization unnecessary. Water retention is also improved.

Bedingt durch die Korngrößenverteilung besitzt das beschriebene Substrat sehr gute Dräneigenschaften, so daß es auch für großflächige Extensivbegrünungen in Einschichtbauweise (ohne separate Dränschicht) geeignet ist.Due to the grain size distribution, the described substrate has very good drainage properties, so that it is also suitable for large-scale extensive greening in a single-layer construction (without a separate drainage layer).

Dies zusammen ermöglicht erhebliche Kosteneinsparungen beim Bau und beim Unterhalt extensiv begrünter Dächer.This together enables significant cost savings in the construction and maintenance of extensively green roofs.
