Furthermore, it is advantageous if a layer of incombustible, poorly heat-conducting plastics, glass fibers or graphite fibers is arranged between the inner shell and the outer shell.
- the suspension devices of the concrete container are advantageously connected to the reinforcement of the inner shell via links and / or deformation elements forming predetermined breaking points. In addition, they can also be connected to the reinforcement of the outer shell. It has also proven to be advantageous if the links and the deformation elements are embedded in concrete or other damping material, for which purpose a concrete is used which has the concrete quality of the outer shell.

Description
Gegenstand der Erfindung ist ein Betonbehälter mit Stahlbewehrung zur Aufnahme bioschädlicher Stoffe, insbesondere zur Aufnahme radioaktiver Abfälle, bestehend aus einem Grundkörper mit Deckel sowie Aufhängeeinrichtungen.The invention relates to a concrete container with steel reinforcement for receiving bio-harmful substances, in particular for receiving radioactive waste, consisting of a base body with a lid and suspension devices.
Bioschädliche Stoffe, wie gefährlicher Industriemüll und insbesondere radioaktive Abfälle aus kerntechnischen Anlagen, Industrie und Krankenhäusern, müssen entsprechend den gesetzlichen Erfordernissen verpackt werden, ehe sie in einer geeigneten Deponie gelagert werden dürfen. Vielfach werden dazu Betonbehälter verwendet, in denen die meist von Blechemballagen umschlossenen bioschädlichen Stoffe eingebracht werden. Die Betonbehälter müssen stabil ausgelegt sein und fallweise radioaktive Strahlung abschirmen, damit die Sicherheit der Biosphäre bei der Handhabung, dem Transport und bei der Zwischen- und Endlagerung gewährleistet ist. Das gilt besonders auch für Unfallsituationen.Bio-harmful substances, such as hazardous industrial waste and in particular radioactive waste from nuclear facilities, industry and hospitals, must be packed according to the legal requirements before they can be stored in a suitable landfill. Concrete containers are often used for this purpose, in which the bio-harmful substances usually enclosed by sheet metal packaging are introduced. The concrete containers must be designed to be stable and, in some cases, shield radioactive radiation so that the safety of the biosphere during handling, transport and during intermediate and final storage is guaranteed. This applies particularly to accident situations.
Bekannte Betonbehälter, wie in den DE-GM 77 36411 und DE-GM 79 20 754 beschrieben, besitzen den Nachteil, daß sie stoßempfindlich sind und bei unsachgemäßer Handhabung gravierende Abplatzungen und Ausbrüche sowie durchgehende Risse im Beton entstehen können, so daß die Integrität der Behälter nicht sichergestellt bleibt. Vor allem bei Transportunfällen, wie Absturz bzw. Fall aus mehreren Metern Höhe und Bränden, können erhebliche Schäden an den Betonbehältern auftreten, wodurch eine Gefährdung der Umgebung durch das bioschädliche Behälterinventar, z. B. durch radioaktive Strahlung, erfolgen kann.Known concrete containers, as described in DE-GM 77 36411 and DE-GM 79 20 754, have the disadvantage that they are sensitive to impact and, if handled improperly, serious chipping and chipping as well as continuous cracks in the concrete can occur, so that the integrity of the container remains unsafe. Especially in the event of transport accidents, such as falling or falling from a height of several meters and fires, considerable damage can occur to the concrete containers, thereby endangering the environment through the bio-harmful container inventory, e.g. B. can be done by radioactive radiation.
Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, einen Betonbehälter mit Stahlbewehrung zur Aufnahme bioschädlicher Stoffe, insbesondere zur Aufnahme radioaktiver Abfälle, zu schaffen, bestehend aus einem Grundkörper mit Deckel sowie Aufhängeeinrichtungen, der auch bei unsachgemäßer Handhabung, Unfällen und Schadensfeuer den sicheren Einschluß des Behälterinventars ohne Gefährdung der Umgebung ermöglicht.The present invention was therefore based on the object of creating a concrete container with steel reinforcement for receiving bio-harmful substances, in particular for receiving radioactive waste, consisting of a base body with a lid and suspension devices which, even in the event of improper handling, accidents and damage fire, ensure the safe containment of the container inventory enables without endangering the environment.
Aus der FR-A-1 411 473 ist ein zweischaliger Behälter zum Aufnehmen radioaktiver Abfälle bekannt, wobei die innere Schale druckfester ausgebildet ist.From FR-A-1 411 473 a two-shell container for receiving radioactive waste is known, the inner shell being designed to be more pressure-resistant.
Diese Aufgabe wurde erfindungsgemäß dadurch gelöst, daß zumindest der Grundkörper aus einer inneren Schale und einer äußeren Schale besteht, wobei der Beton der dünneren äußeren Schale eine geringer Druckfestigkeit als der Beton der innere Schale besitzt und die inneren Schale mit der äußeren Schale durch Sollbruchstellen und Verformungsbereich aufweisende Anker verbunden ist. Auch der Deckel des Behälters kann entsprechend aufgebaut sein.This object was achieved in that at least the base body consists of an inner shell and an outer shell, the concrete of the thinner outer shell having a lower compressive strength than the concrete of the inner shell and the inner shell with the outer shell due to predetermined breaking points and deformation area having anchors is connected. The lid of the container can also be constructed accordingly.
Vorzugsweise beträgt die Dicke der äußeren Schale 2 bis 6 cm und ist aus einem porösen Beton gefertigt. Es ist auch günstig, wenn der Beton der äußeren Schale geschäumte Kunststoffkügelchen enthält. Weiterhin ist es vorteilhaft, wenn zwischen der inneren Schale und der äußeren Schale eine Schicht aus nicht brennbaren schlecht wärmeleitenden Kunststoffen, Glasfasern oder Grafitfasern angeordnet ist.The thickness of the outer shell is preferably 2 to 6 cm and is made of a porous concrete. It is also beneficial if the concrete of the outer shell contains foamed plastic beads. Furthermore, it is advantageous if a layer of incombustible, poorly heat-conducting plastics, glass fibers or graphite fibers is arranged between the inner shell and the outer shell.
Die Aufhängeeinrichtungen des Betonbehälters sind vorteilhafterweise über Sollbruchstellen bildende Verknüpfungen und/oder Verformungselemente mit der Bewehrung der inneren Schale verbunden. Zusätzlich können sie auch noch mit der Bewehrung der äußeren Schale verbunden sein. Als günstig hat es sich außerdem erwiesen, wenn die Verknüpfungen und die Verformungselemente in Beton oder anderes Dämpfungsmaterial eingebettet sind, wobei hierzu ein Beton verwendet wird, der die Betonqualität der äußeren Schale besitzt.The suspension devices of the concrete container are advantageously connected to the reinforcement of the inner shell via links and / or deformation elements forming predetermined breaking points. In addition, they can also be connected to the reinforcement of the outer shell. It has also proven to be advantageous if the links and the deformation elements are embedded in concrete or other damping material, for which purpose a concrete is used which has the concrete quality of the outer shell.
Die Abbildungen bis IV zeigen schematisch einen erfindungsgemäßen Betonbehälter in beispielhafter Ausführungsform, wobei Abbildung 1 einen Längsschnitt, Abbildung 11 die Details zwischen innerer und äußerer Schale und die Abbildungen 111 und IV die Anordnung der Aufhängeeinrichtungen wiedergeben.Figures to IV schematically show a concrete container according to the invention in an exemplary embodiment, Figure 1 showing a longitudinal section, Figure 11 the details between the inner and outer shell and Figures 111 and IV the arrangement of the suspension devices.
Der zylindrische, würfel- oder quaderförmige Betonbehälter, besteht aus einem Grundkörper (1) und einem Deckel (5), die beide mit einer Stahlbewehrung (7) versehen sind. Außerdem sind am Betonbehälter Aufhängeeinrichtungen in Form von Tragösen (14) oder Eckbeschlägen (16) befestigt. Im Behälterinnern befinden sich die radioaktiven Stoffe, zumeist in einem Blechfaß (6) eingeschlossen. Der Zwischenraum zwischen Blechfaß (6), Grundkörper (1) und Deckel (5) kann ein Verfüllmaterial enthalten. Der Grundkörper (1) und gegebenenfalls auch der Deckel (5) bestehen aus einer inneren Schale (2) und einer äußeren Schale (3). Die innere Schale (2) ist aus Beton hoher Druckfestigkeit, z. B. Schwerbeton (Druckfestigkeit: 60-64 N/mm2, Dichte: 3,5-3,7 g/cm3 gefertigt und weist gegenüber der aus Beton niedrigerer Festigkeit hergestellten äußeren Schale (3) eine wesentliche größere Dicke auf. Während die Betondicke der inneren Schale (2) oft 15 bis 20 cm betragen kann, ist die Dicke der äußeren Schale (3) geringer als 10 cm. Die äußere Schale (3) ist mit einer Bewehrung (8) versehen, die im Vergleich zur starken Stahlbewehrung (7) der inneren Schale (2), welche die Sicherheits-, Trag-, Stabilitäts- und gegebenenfalls die hauptsächliche Strahlenabschirmfunktion erfüllt, von geringerer Stärke ist. Beispielsweise besteht die Bewehrung (8) aus einem Maschendrahtgeflecht, gewelltem Lochblech oder aus einer geeigneten Drahtspirale. Die äußere Schale (3) übernimmt wegen der entsprechend gewählten geringen Betongüte in Verbindung mit der geringeren Schichtdicke und der schwächeren Bewehrung energieverzehrende Stoßdämpfungs- und Sollbruchsfunktionen am Behälter.The cylindrical, cube-shaped or cuboid concrete container consists of a base body (1) and a cover (5), both of which are provided with steel reinforcement (7). In addition, suspension devices in the form of eyelets (14) or corner fittings (16) are attached to the concrete container. The radioactive substances are located inside the container, mostly enclosed in a metal barrel (6). The space between the metal barrel (6), base body (1) and cover (5) can contain a backfill material. The base body (1) and optionally also the cover (5) consist of an inner shell (2) and an outer shell (3). The inner shell (2) is made of concrete with high compressive strength, e.g. B. Heavy concrete (compressive strength: 60-64 N / mm 2 , density: 3.5-3.7 g / cm 3) and has a significantly greater thickness than the outer shell (3) made of lower strength concrete Concrete thickness of the inner shell (2) can often be 15 to 20 cm, the thickness of the outer shell (3) is less than 10 cm (7) of the inner shell (2), which fulfills the safety, carrying, stability and possibly the main radiation shielding function, is of lesser strength, for example the reinforcement (8) consists of a wire mesh, corrugated perforated plate or a suitable wire spiral The outer shell (3) takes on energy-absorbing shock absorption and, owing to the correspondingly selected low concrete quality in connection with the smaller layer thickness and the weaker reinforcement Breakage functions on the container.
Beim Schadensfall wird nur die äußere Schale (3) beschädigt oder zerbricht, ohne daß die Sicherheitsfunktionen der inneren Schale (2) beeinträchtigt werden. Das gilt auch für ein Schadensfeuer, das allenfalls die äußere Schale (2) beschädigt. Als günstig für die Stoßdämpfung hat es sich erwiesen, wenn die äußere Schale (3) eine Dicke von 3 bis 6 cm aufweist. Aus Gewichts-, Dämpfungs- und Wärmeisolationsgründen ist es vorteilhaft, als Material für die äußere Schale (3) porösen Beton zu verwenden. Dazu geeignet sind u.a. Gasbeton, Naturbimsbeton, Blähton- und Blähschieferbeton, Hüttenbimsbeton und Aschesinterbeton. Besonders vorteilhaft ist es, wenn der Beton der äußeren Schale (3) geschäumte Kunststoffkügelchen enthält.In the event of damage, only the outer shell (3) is damaged or broken without the safety functions of the inner shell (2) being impaired. This also applies to a damage fire that may damage the outer shell (2). It has proven to be favorable for shock absorption if the outer shell (3) has a thickness of 3 to 6 cm. For reasons of weight, damping and heat insulation, it is advantageous to use porous concrete as the material for the outer shell (3). Suitable for this include Gas concrete, natural pumice concrete, expanded clay and expanded slate concrete, cottage pumice concrete and ash sinter concrete. It is particularly advantageous if the concrete of the outer shell (3) contains foamed plastic balls.
In manchen Anwendungsfällen ist es günstig, wenn zwischen der inneren Schale (2) und der äußeren Schale (3) eine Schicht (4) aus nicht brennbaren Kunststoffen, z. B. in geschäumter Form, Glasfasern, z. B. als Matten, oder Grafitfasern z. B. als Flies, angeordnet ist. Diese Schicht (4) verbessert wegen der elastischen Eigenschaften der genannten Materialien zusätzlich die Stoßdämpfung und Wärmeisolation.In some applications, it is advantageous if a layer (4) made of non-combustible plastics, eg, between the inner shell (2) and the outer shell (3). B. in foamed form, glass fibers, for. B. as mats, or graphite fibers such. B. is arranged as a tile. This layer (4) additionally improves shock absorption and thermal insulation because of the elastic properties of the materials mentioned.
Der erfindungsgemäße Betonbehälter ist einfach herstellbar. Zunächst kann die innere Schale (2), die außen mit Ankern (10) versehen ist, gefertigt werden. Dabei ist es gegebenenfalls möglich, den äußeren Bereich der inneren Schale (2) durch Eingießen von Matten oder Draht zu verstärken. Anschließend wird durch Ausgießen des Zwischenraumes zwischen der inneren Schale (2) und einer Betongußform die äußere Schale (3) über die Ankerbefestigungen (11) angegossen. Die Schicht (4) wird vor dem Betonieren der äußeren Schale (3) um die bereits betonierte innere Schale (2) gelegt. Auch das Aufbetonieren der äußeren Schale (3) im Deckel-und Stirnseitenbereich bereitet keine Schwierigkeiten.The concrete container according to the invention is easy to manufacture. First, the inner shell (2), which is provided with anchors (10) on the outside, can be manufactured. It may be possible to reinforce the outer area of the inner shell (2) by pouring in mats or wire. Then, by pouring out the space between the inner shell (2) and a concrete casting mold, the outer shell (3) is cast over the anchor fasteners (11). The layer (4) is placed around the already concreted inner shell (2) before concreting the outer shell (3). Concreting the outer shell (3) in the area of the cover and the end face also presents no difficulties.
Die innere Schale (2) wird mit der äußeren Schale (3) durch Sollbruchstellen (11) und Verformungsbereiche (12) aufweisende Anker (13) verbunden. Als Anker (13) mit Sollbruchstellen (11) können Eisenstäbe oder Drähte verwendet werden, deren Querschnitt an der Sollbruchstelle (11), die sich entweder innerhalb der äußeren Schale (3), innerhalb der Schicht (4) oder im Nahtstellenbereich beider Schalen befinden, entsprechend geschwächt ist. Auch sind Anker, die sich bei Überschreitung einer zulässigen Druckbeanspruchung durch Abscheren als zwei Teile ineinanderschieben, einsetzbar. Als Anker (13) mit Verformungsbereichen (12), die sich in entsprechenden Positionen wie die Sollbruchstellen (11) befinden können, sind Anker mit Sicken oder spiralfederähnliche Anker einsetzbar. Die Anker (13) nehmen entweder Verformungsenergie auf oder bewirken ein gezieltes Abplatzen der äußeren Schale (3) und deren energieverzehrendes Zerbröseln im Bedarfsfall.The inner shell (2) is connected to the outer shell (3) by predetermined breaking points (11) and deformation areas (12) having anchors (13). Iron rods or wires can be used as anchors (13) with predetermined breaking points (11), the cross-section of which at the predetermined breaking point (11), which are located either within the outer shell (3), within the layer (4) or in the interface area of the two shells, is weakened accordingly. Anchors can also be used that slide into one another as two parts when a permissible pressure load is exceeded due to shearing. Anchors (13) with deformation areas (12), which can be located in corresponding positions as the predetermined breaking points (11), can be used with anchors or beads similar to spiral springs. The anchors (13) either absorb deformation energy or cause the outer shell (3) to flake off and crumble to dissipate energy if necessary.
Besonders günstig ist es, wenn die Aufhängeeinrichtungen (14, 16) über Sollbruchstellen bildende Verknüpfungen (15, 19) und/oder Verformungselemente (18) mit der Bewehrung (7) verbunden sind, wobei die Verknüpfungen (15, 19) bzw. die Verformungselemente (18) von Beton (20), dessen Qualität der Betonqualität der äußeren Schicht (3) entspricht, oder von anderem Dämpfungsmaterial umgeben sind. Vorteilhafterweise werden die Aufhängeeinrichtungen (14, 16) zusätzlich mit der Bewehrung (8) der äußeren Schale (3) verbunden.It is particularly favorable if the suspension devices (14, 16) are connected to the reinforcement (7) via links (15, 19) and / or deformation elements (18) forming predetermined breaking points, the links (15, 19) or the deformation elements (18) of concrete (20), the quality of which corresponds to the concrete quality of the outer layer (3), or are surrounded by other damping material. Advantageously, the suspension devices (14, 16) are additionally connected to the reinforcement (8) of the outer shell (3).
Bei einem Fall oder starken Stoß auf die Tragösen (14) oder auf die ebenfalls als Aufhängeeinrichtungen dienenden Eckbeschläge (16), letztere meist bei würfel- oder quaderförmigen Betonbehältern verwendet, deckel- und auch oft bodenseitig angebracht, wird die Energie über die Sollbruchstellen bildende Verknüpfungen (15), oder Verformungselemente (18) verzehrt.In the event of a fall or a strong impact on the lifting eyes (14) or on the corner fittings (16), which also serve as suspension devices, the latter mostly used for cube-shaped or cuboid concrete containers, attached to the lid and often on the bottom, the energy is created via the links forming the predetermined breaking points (15), or deformation elements (18) consumed.
So ist es beispielsweise möglich, die Tragösen (14) an die Bewehrung (7) der inneren Schale (2) seitlich z. B. durch eine Schweißnaht zu verbinden, daß diese Verknüpfung (15) als Sollbruchstelle bei unzulässiger Belastung wirksam wird. Der in einer Schutzhülse (17) befindliche Beton (20) wirkt dann als stoßdämpfender Puffer. Die innere Schale (2) wird auf diese Weise geschützt. Die Tragöse (14) kann auch zusätzlich an der Bewehrung (8) befestigt sein. Erfolgt ein starker Stoß oder Sturz auf die Eckbeschläge (16), wird die zu verzehrende Energie teils über die Bewehrung (8) der äußeren Schale (3) teils über Verformungselemente (18) bzw. als Sollbruchstellen ausgebildete Verknüpfungen (19) analog der Sollbruchstelle an den Tragösen (14) auf den dann zerbröckelnden Beton (20) übertragen und vernichtet. Anstatt des Betons (20) ist auch anderes geeignetes Dämpfungsmaterial verwendbar.For example, it is possible to attach the eyelets (14) to the reinforcement (7) of the inner shell (2) laterally, e.g. B. to connect by a weld that this link (15) is effective as a predetermined breaking point with impermissible load. The concrete (20) located in a protective sleeve (17) then acts as a shock-absorbing buffer. The inner shell (2) is protected in this way. The lifting eye (14) can also be attached to the reinforcement (8). If there is a strong impact or fall on the corner fittings (16), the energy to be consumed is partly analogous to the predetermined breaking point via the reinforcement (8) of the outer shell (3) partly via deformation elements (18) or links (19) designed as predetermined breaking points the lifting eyes (14) transferred to the then crumbling concrete (20) and destroyed. Instead of the concrete (20), other suitable damping material can also be used.
Mit seiner äußeren Schale (3) besitzt der erfindungsgemäße Betonbehälter einen wirksamen und billigen Schutz der Integrität der inneren Schale (2) bei Fall, Stoß und Brand. Kosten-, Material- und Handhabungsaufwand sind gering. In vielen Anwendungsfällen kann der erfindungsgemäße Betonbehälter sogar aufwendige und teure Stahlbehälter ersetzen.With its outer shell (3), the concrete container according to the invention has an effective and inexpensive protection of the integrity of the inner shell (2) in the event of a fall, impact or fire. Costs, materials and handling are low. In many applications, the concrete container according to the invention can even replace complex and expensive steel containers.
