Erläuterung:Explanation:
Praxisi Practice i
Im Falle eines Leekens oder Berstens von Behältern aas Kunststoff oder Metall dienen Wannen zum Auffangen der eingelagertes. Medien.In the event of a leak or bursting of plastic or metal containers, trays are used to collect the stored media.
Bei größeren Anlagen sind sogenannte Auf fangwannen oder Behälterlager meistens in Stahlbeton hergestellt.In larger plants, so-called collecting trays or container storage areas are usually made of reinforced concrete.
Bas neugefaßte Wasserhaushaltgesetz vom Jan. 87 bringt für die Betreiber von Behälterlagern und Wannen aus Stahlbeton die Auflage einenThe revised Water Resources Act of January 87 imposes on operators of tank storage facilities and tanks made of reinforced concrete the requirement to
Dichtheits-Hachweis (nach WHG § 19) zu führen.Proof of tightness (according to WHG § 19) must be provided.
Stahlbetonwände und -Bodenplatten älterer Anlagen haben oft Zwäng- oder Spaltrisse. Sie unter Auflage des WE-Gesetzes abgedichteten Anlagen( mit Polyuretan oder Bpoxin verpreSto Bisse oder Anlagen) erfordern einen Prüfnachweis.Reinforced concrete walls and floor slabs of older systems often have stress or split cracks. The systems sealed under the WE Act (with polyurethane or pressed concrete) require proof of testing.
Bas vorgestellte Gerät ermöglicht ein netaunabhängiges überprüfen der Dichtheit b*i Stahlbetonbodenplatten ,-Wänden und in Biseebftreichen in allen Lagen und Höhen*The device presented enables network-independent checking of the tightness of reinforced concrete floor slabs, walls and in areas with low pressure in all positions and heights*
Nach Entfernen der Bichtungskappe wird Wasser (Einfgrbuag sinnvollI) in den Behälter (2) eingefüllt. After removing the sealing cap, water (insertion advisable) is poured into the container (2).
Das Befüllen erfolgt bei geschlossenem Dw?ohgang#~ ventil (8) bis zu etwa 4/9 des oa. 4o ml-Behältera. »aoh Teraohrauben der Behälterd4,ohtungekappe vird mittels Luftpump« (fahrrad-ffußpufltpe) über das Ventil (1) der erforderliehe Druck aufgefenut*Filling is carried out with the pressure relief valve (8) closed up to about 4/9 of the above-mentioned 40 ml container. The required pressure is created by unscrewing the container's 4 -valve cap using an air pump (bicycle foot pump) via the valve (1).

Due to the discoloration of the test liquid, leaks can be easily identified, even if liquid is leaking.
Darüber hinaus können auoh Eindringt!efen bei Stahlbetonteilen durch Aufstemmen oder Nachbohren durch die farbliche Markierung nach der "Druckprüfung11 leichter kontrolliert werden.In addition, penetration depths in reinforced concrete parts can also be more easily checked by prying or re-drilling thanks to the colour marking after the "pressure test 11" .
